In order to handle tests when input lines are enormously long, pcretest has + been re-factored so that it automatically extends its buffers when + necessary. The code is crude, but this _is_ just a test program. The + default size has been increased from 32K to 50K. + + 2. The code in pcre_study() was using the value of the re argument before + testing it for NULL. (Of course, in any sensible call of the function, it + won't be NULL.) + + 3. The memmove() emulation function in pcre_internal.h, which is used on + systems that lack both memmove() and bcopy() - that is, hardly ever - + was missing a "static" storage class specifier. + + 4. When UTF-8 mode was not set, PCRE looped when compiling certain patterns + containing an extended class (one that cannot be represented by a bitmap + because it contains high-valued characters or Unicode property items, e.g. + [\pZ]). Almost always one would set UTF-8 mode when processing such a + pattern, but PCRE should not loop if you do not (it no longer does). + [Detail: two cases were found: (a) a repeated subpattern containing an + extended class; (b) a recursive reference to a subpattern that followed a + previous extended class. It wasn't skipping over the extended class + correctly when UTF-8 mode was not set.] + + 5. A negated single-character class was not being recognized as fixed-length + in lookbehind assertions such as (?<=[^f]), leading to an incorrect + compile error "lookbehind assertion is not fixed length". + + 6. The RunPerlTest auxiliary script was showing an unexpected difference + between PCRE and Perl for UTF-8 tests. It turns out that it is hard to + write a Perl script that can interpret lines of an input file either as + byte characters or as UTF-8, which is what "perltest" was being required to + do for the non-UTF-8 and UTF-8 tests, respectively. Essentially what you + can't do is switch easily at run time between having the "use utf8;" pragma + or not. In the end, I fudged it by using the RunPerlTest script to insert + "use utf8;" explicitly for the UTF-8 tests. + + 7. In multiline (/m) mode, PCRE was matching ^ after a terminating newline at + the end of the subject string, contrary to the documentation and to what + Perl does. This was true of both matching functions. Now it matches only at + the start of the subject and immediately after *internal* newlines. + + 8. A call of pcre_fullinfo() from pcretest to get the option bits was passing + a pointer to an int instead of a pointer to an unsigned long int. This + caused problems on 64-bit systems. + + 9. Applied a patch from the folks at Google to pcrecpp.cc, to fix "another + instance of the 'standard' template library not being so standard". + +10. There was no check on the number of named subpatterns nor the maximum + length of a subpattern name. The product of these values is used to compute + the size of the memory block for a compiled pattern. By supplying a very + long subpattern name and a large number of named subpatterns, the size + computation could be caused to overflow. This is now prevented by limiting + the length of names to 32 characters, and the number of named subpatterns + to 10,000. + +11. Subpatterns that are repeated with specific counts have to be replicated in + the compiled pattern. The size of memory for this was computed from the + length of the subpattern and the repeat count. The latter is limited to + 65535, but there was no limit on the former, meaning that integer overflow + could in principle occur. The compiled length of a repeated subpattern is + now limited to 30,000 bytes in order to prevent this. + +12. Added the optional facility to have named substrings with the same name. + +13. Added the ability to use a named substring as a condition, using the + Python syntax: (?(name)yes|no). This overloads (?(R)... and names that + are numbers (not recommended). Forward references are permitted. + +14. Added forward references in named backreferences (if you see what I mean). + +15. In UTF-8 mode, with the PCRE_DOTALL option set, a quantified dot in the + pattern could run off the end of the subject. For example, the pattern + "(?s)(.{1,5})"8 did this with the subject "ab". + +16. If PCRE_DOTALL or PCRE_MULTILINE were set, pcre_dfa_exec() behaved as if + PCRE_CASELESS was set when matching characters that were quantified with ? + or *. + +17. A character class other than a single negated character that had a minimum + but no maximum quantifier - for example [ab]{6,} - was not handled + correctly by pce_dfa_exec(). It would match only one character. + +18. A valid (though odd) pattern that looked like a POSIX character + class but used an invalid character after [ (for example [[,abc,]]) caused + pcre_compile() to give the error "Failed: internal error: code overflow" or + in some cases to crash with a glibc free() error. This could even happen if + the pattern terminated after [[ but there just happened to be a sequence of + letters, a binary zero, and a closing ] in the memory that followed. + +19. Perl's treatment of octal escapes in the range \400 to \777 has changed + over the years. Originally (before any Unicode support), just the bottom 8 + bits were taken. Thus, for example, \500 really meant \100. Nowadays the + output from "man perlunicode" includes this: + + The regular expression compiler produces polymorphic opcodes. That + is, the pattern adapts to the data and automatically switches to + the Unicode character scheme when presented with Unicode data--or + instead uses a traditional byte scheme when presented with byte + data. + + Sadly, a wide octal escape does not cause a switch, and in a string with + no other multibyte characters, these octal escapes are treated as before. + Thus, in Perl, the pattern /\500/ actually matches \100 but the pattern + /\500|\x{1ff}/ matches \500 or \777 because the whole thing is treated as a + Unicode string. + + I have not perpetrated such confusion in PCRE. Up till now, it took just + the bottom 8 bits, as in old Perl. I have now made octal escapes with + values greater than \377 illegal in non-UTF-8 mode. In UTF-8 mode they + translate to the appropriate multibyte character. + +29. Applied some refactoring to reduce the number of warnings from Microsoft + and Borland compilers. This has included removing the fudge introduced + seven years ago for the OS/2 compiler (see 2.02/2 below) because it caused + a warning about an unused variable. + +21. PCRE has not included VT (character 0x0b) in the set of whitespace + characters since release 4.0, because Perl (from release 5.004) does not. + [Or at least, is documented not to: some releases seem to be in conflict + with the documentation.] However, when a pattern was studied with + pcre_study() and all its branches started with \s, PCRE still included VT + as a possible starting character. Of course, this did no harm; it just + caused an unnecessary match attempt. + +22. Removed a now-redundant internal flag bit that recorded the fact that case + dependency changed within the pattern. This was once needed for "required + byte" processing, but is no longer used. This recovers a now-scarce options + bit. Also moved the least significant internal flag bit to the most- + significant bit of the word, which was not previously used (hangover from + the days when it was an int rather than a uint) to free up another bit for + the future. + +23. Added support for CRLF line endings as well as CR and LF. As well as the + default being selectable at build time, it can now be changed at runtime + via the PCRE_NEWLINE_xxx flags. There are now options for pcregrep to + specify that it is scanning data with non-default line endings. + +24. Changed the definition of CXXLINK to make it agree with the definition of + LINK in the Makefile, by replacing LDFLAGS to CXXFLAGS. + +25. Applied Ian Taylor's patches to avoid using another stack frame for tail + recursions. This makes a big different to stack usage for some patterns. + +26. If a subpattern containing a named recursion or subroutine reference such + as (?P>B) was quantified, for example (xxx(?P>B)){3}, the calculation of + the space required for the compiled pattern went wrong and gave too small a + value. Depending on the environment, this could lead to "Failed: internal + error: code overflow at offset 49" or "glibc detected double free or + corruption" errors. + +27. Applied patches from Google (a) to support the new newline modes and (b) to + advance over multibyte UTF-8 characters in GlobalReplace. + +28. Change free() to pcre_free() in pcredemo.c. Apparently this makes a + difference for some implementation of PCRE in some Windows version. + +29. Added some extra testing facilities to pcretest: + + \q<number> in a data line sets the "match limit" value + \Q<number> in a data line sets the "match recursion limt" value + -S <number> sets the stack size, where <number> is in megabytes + + The -S option isn't available for Windows. + + +Version 6.6 06-Feb-06 +--------------------- + + 1. Change 16(a) for 6.5 broke things, because PCRE_DATA_SCOPE was not defined + in pcreposix.h. I have copied the definition from pcre.h. + + 2. Change 25 for 6.5 broke compilation in a build directory out-of-tree + because pcre.h is no longer a built file. + + 3. Added Jeff Friedl's additional debugging patches to pcregrep. These are + not normally included in the compiled code. + + +Version 6.5 01-Feb-06 +--------------------- + + 1. When using the partial match feature with pcre_dfa_exec(), it was not + anchoring the second and subsequent partial matches at the new starting + point. This could lead to incorrect results. For example, with the pattern + /1234/, partially matching against "123" and then "a4" gave a match. + + 2. Changes to pcregrep: + + (a) All non-match returns from pcre_exec() were being treated as failures + to match the line. Now, unless the error is PCRE_ERROR_NOMATCH, an + error message is output. Some extra information is given for the + PCRE_ERROR_MATCHLIMIT and PCRE_ERROR_RECURSIONLIMIT errors, which are + probably the only errors that are likely to be caused by users (by + specifying a regex that has nested indefinite repeats, for instance). + If there are more than 20 of these errors, pcregrep is abandoned. + + (b) A binary zero was treated as data while matching, but terminated the + output line if it was written out. This has been fixed: binary zeroes + are now no different to any other data bytes. + + (c) Whichever of the LC_ALL or LC_CTYPE environment variables is set is + used to set a locale for matching. The --locale=xxxx long option has + been added (no short equivalent) to specify a locale explicitly on the + pcregrep command, overriding the environment variables. + + (d) When -B was used with -n, some line numbers in the output were one less + than they should have been. + + (e) Added the -o (--only-matching) option. + + (f) If -A or -C was used with -c (count only), some lines of context were + accidentally printed for the final match. + + (g) Added the -H (--with-filename) option. + + (h) The combination of options -rh failed to suppress file names for files + that were found from directory arguments. + + (i) Added the -D (--devices) and -d (--directories) options. + + (j) Added the -F (--fixed-strings) option. + + (k) Allow "-" to be used as a file name for -f as well as for a data file. + + (l) Added the --colo(u)r option. + + (m) Added Jeffrey Friedl's -S testing option, but within #ifdefs so that it + is not present by default. + + 3. A nasty bug was discovered in the handling of recursive patterns, that is, + items such as (?R) or (?1), when the recursion could match a number of + alternatives. If it matched one of the alternatives, but subsequently, + outside the recursion, there was a failure, the code tried to back up into + the recursion. However, because of the way PCRE is implemented, this is not + possible, and the result was an incorrect result from the match. + + In order to prevent this happening, the specification of recursion has + been changed so that all such subpatterns are automatically treated as + atomic groups. Thus, for example, (?R) is treated as if it were (?>(?R)). + + 4. I had overlooked the fact that, in some locales, there are characters for + which isalpha() is true but neither isupper() nor islower() are true. In + the fr_FR locale, for instance, the \xAA and \xBA characters (ordmasculine + and ordfeminine) are like this. This affected the treatment of \w and \W + when they appeared in character classes, but not when they appeared outside + a character class. The bit map for "word" characters is now created + separately from the results of isalnum() instead of just taking it from the + upper, lower, and digit maps. (Plus the underscore character, of course.) + + 5. The above bug also affected the handling of POSIX character classes such as + [[:alpha:]] and [[:alnum:]]. These do not have their own bit maps in PCRE's + permanent tables. Instead, the bit maps for such a class were previously + created as the appropriate unions of the upper, lower, and digit bitmaps. + Now they are created by subtraction from the [[:word:]] class, which has + its own bitmap. + + 6. The [[:blank:]] character class matches horizontal, but not vertical space. + It is created by subtracting the vertical space characters (\x09, \x0a, + \x0b, \x0c) from the [[:space:]] bitmap. Previously, however, the + subtraction was done in the overall bitmap for a character class, meaning + that a class such as [\x0c[:blank:]] was incorrect because \x0c would not + be recognized. This bug has been fixed. + + 7. Patches from the folks at Google: + + (a) pcrecpp.cc: "to handle a corner case that may or may not happen in + real life, but is still worth protecting against". + + (b) pcrecpp.cc: "corrects a bug when negative radixes are used with + regular expressions". + + (c) pcre_scanner.cc: avoid use of std::count() because not all systems + have it. + + (d) Split off pcrecpparg.h from pcrecpp.h and had the former built by + "configure" and the latter not, in order to fix a problem somebody had + with compiling the Arg class on HP-UX. + + (e) Improve the error-handling of the C++ wrapper a little bit. + + (f) New tests for checking recursion limiting. + + 8. The pcre_memmove() function, which is used only if the environment does not + have a standard memmove() function (and is therefore rarely compiled), + contained two bugs: (a) use of int instead of size_t, and (b) it was not + returning a result (though PCRE never actually uses the result). + + 9. In the POSIX regexec() interface, if nmatch is specified as a ridiculously + large number - greater than INT_MAX/(3*sizeof(int)) - REG_ESPACE is + returned instead of calling malloc() with an overflowing number that would + most likely cause subsequent chaos. + +10. The debugging option of pcretest was not showing the NO_AUTO_CAPTURE flag. + +11. The POSIX flag REG_NOSUB is now supported. When a pattern that was compiled + with this option is matched, the nmatch and pmatch options of regexec() are + ignored. + +12. Added REG_UTF8 to the POSIX interface. This is not defined by POSIX, but is + provided in case anyone wants to the the POSIX interface with UTF-8 + strings. + +13. Added CXXLDFLAGS to the Makefile parameters to provide settings only on the + C++ linking (needed for some HP-UX environments). + +14. Avoid compiler warnings in get_ucpname() when compiled without UCP support + (unused parameter) and in the pcre_printint() function (omitted "default" + switch label when the default is to do nothing). + +15. Added some code to make it possible, when PCRE is compiled as a C++ + library, to replace subject pointers for pcre_exec() with a smart pointer + class, thus making it possible to process discontinuous strings. + +16. The two macros PCRE_EXPORT and PCRE_DATA_SCOPE are confusing, and perform + much the same function. They were added by different people who were trying + to make PCRE easy to compile on non-Unix systems. It has been suggested + that PCRE_EXPORT be abolished now that there is more automatic apparatus + for compiling on Windows systems. I have therefore replaced it with + PCRE_DATA_SCOPE. This is set automatically for Windows; if not set it + defaults to "extern" for C or "extern C" for C++, which works fine on + Unix-like systems. It is now possible to override the value of PCRE_DATA_ + SCOPE with something explicit in config.h. In addition: + + (a) pcreposix.h still had just "extern" instead of either of these macros; + I have replaced it with PCRE_DATA_SCOPE. + + (b) Functions such as _pcre_xclass(), which are internal to the library, + but external in the C sense, all had PCRE_EXPORT in their definitions. + This is apparently wrong for the Windows case, so I have removed it. + (It makes no difference on Unix-like systems.) + +17. Added a new limit, MATCH_LIMIT_RECURSION, which limits the depth of nesting + of recursive calls to match(). This is different to MATCH_LIMIT because + that limits the total number of calls to match(), not all of which increase + the depth of recursion. Limiting the recursion depth limits the amount of + stack (or heap if NO_RECURSE is set) that is used. The default can be set + when PCRE is compiled, and changed at run time. A patch from Google adds + this functionality to the C++ interface. + +18. Changes to the handling of Unicode character properties: + + (a) Updated the table to Unicode 4.1.0. + + (b) Recognize characters that are not in the table as "Cn" (undefined). + + (c) I revised the way the table is implemented to a much improved format + which includes recognition of ranges. It now supports the ranges that + are defined in UnicodeData.txt, and it also amalgamates other + characters into ranges. This has reduced the number of entries in the + table from around 16,000 to around 3,000, thus reducing its size + considerably. I realized I did not need to use a tree structure after + all - a binary chop search is just as efficient. Having reduced the + number of entries, I extended their size from 6 bytes to 8 bytes to + allow for more data. + + (d) Added support for Unicode script names via properties such as \p{Han}. + +19. In UTF-8 mode, a backslash followed by a non-Ascii character was not + matching that character. + +20. When matching a repeated Unicode property with a minimum greater than zero, + (for example \pL{2,}), PCRE could look past the end of the subject if it + reached it while seeking the minimum number of characters. This could + happen only if some of the characters were more than one byte long, because + there is a check for at least the minimum number of bytes. + +21. Refactored the implementation of \p and \P so as to be more general, to + allow for more different types of property in future. This has changed the + compiled form incompatibly. Anybody with saved compiled patterns that use + \p or \P will have to recompile them. + +22. Added "Any" and "L&" to the supported property types. + +23. Recognize \x{...} as a code point specifier, even when not in UTF-8 mode, + but give a compile time error if the value is greater than 0xff. + +24. The man pages for pcrepartial, pcreprecompile, and pcre_compile2 were + accidentally not being installed or uninstalled. + +25. The pcre.h file was built from pcre.h.in, but the only changes that were + made were to insert the current release number. This seemed silly, because + it made things harder for people building PCRE on systems that don't run + "configure". I have turned pcre.h into a distributed file, no longer built + by "configure", with the version identification directly included. There is + no longer a pcre.h.in file. + + However, this change necessitated a change to the pcre-config script as + well. It is built from pcre-config.in, and one of the substitutions was the + release number. I have updated configure.ac so that ./configure now finds + the release number by grepping pcre.h. + +26. Added the ability to run the tests under valgrind. + + +Version 6.4 05-Sep-05 +--------------------- + + 1. Change 6.0/10/(l) to pcregrep introduced a bug that caused separator lines + "--" to be printed when multiple files were scanned, even when none of the + -A, -B, or -C options were used. This is not compatible with Gnu grep, so I + consider it to be a bug, and have restored the previous behaviour. + + 2. A couple of code tidies to get rid of compiler warnings. + + 3. The pcretest program used to cheat by referring to symbols in the library + whose names begin with _pcre_. These are internal symbols that are not + really supposed to be visible externally, and in some environments it is + possible to suppress them. The cheating is now confined to including + certain files from the library's source, which is a bit cleaner. + + 4. Renamed pcre.in as pcre.h.in to go with pcrecpp.h.in; it also makes the + file's purpose clearer. + + 5. Reorganized pcre_ucp_findchar(). + + +Version 6.3 15-Aug-05 +--------------------- + + 1. The file libpcre.pc.in did not have general read permission in the tarball. + + 2. There were some problems when building without C++ support: + + (a) If C++ support was not built, "make install" and "make test" still + tried to test it. + + (b) There were problems when the value of CXX was explicitly set. Some + changes have been made to try to fix these, and ... + + (c) --disable-cpp can now be used to explicitly disable C++ support. + + (d) The use of @CPP_OBJ@ directly caused a blank line preceded by a + backslash in a target when C++ was disabled. This confuses some + versions of "make", apparently. Using an intermediate variable solves + this. (Same for CPP_LOBJ.) + + 3. $(LINK_FOR_BUILD) now includes $(CFLAGS_FOR_BUILD) and $(LINK) + (non-Windows) now includes $(CFLAGS) because these flags are sometimes + necessary on certain architectures. + + 4. Added a setting of -export-symbols-regex to the link command to remove + those symbols that are exported in the C sense, but actually are local + within the library, and not documented. Their names all begin with + "_pcre_". This is not a perfect job, because (a) we have to except some + symbols that pcretest ("illegally") uses, and (b) the facility isn't always + available (and never for static libraries). I have made a note to try to + find a way round (a) in the future. + + +Version 6.2 01-Aug-05 +--------------------- + + 1. There was no test for integer overflow of quantifier values. A construction + such as {1111111111111111} would give undefined results. What is worse, if + a minimum quantifier for a parenthesized subpattern overflowed and became + negative, the calculation of the memory size went wrong. This could have + led to memory overwriting. + + 2. Building PCRE using VPATH was broken. Hopefully it is now fixed. + + 3. Added "b" to the 2nd argument of fopen() in dftables.c, for non-Unix-like + operating environments where this matters. + + 4. Applied Giuseppe Maxia's patch to add additional features for controlling + PCRE options from within the C++ wrapper. + + 5. Named capturing subpatterns were not being correctly counted when a pattern + was compiled. This caused two problems: (a) If there were more than 100 + such subpatterns, the calculation of the memory needed for the whole + compiled pattern went wrong, leading to an overflow error. (b) Numerical + back references of the form \12, where the number was greater than 9, were + not recognized as back references, even though there were sufficient + previous subpatterns. + + 6. Two minor patches to pcrecpp.cc in order to allow it to compile on older + versions of gcc, e.g. 2.95.4. + + +Version 6.1 21-Jun-05 +--------------------- + + 1. There was one reference to the variable "posix" in pcretest.c that was not + surrounded by "#if !defined NOPOSIX". + + 2. Make it possible to compile pcretest without DFA support, UTF8 support, or + the cross-check on the old pcre_info() function, for the benefit of the + cut-down version of PCRE that is currently imported into Exim. + + 3. A (silly) pattern starting with (?i)(?-i) caused an internal space + allocation error. I've done the easy fix, which wastes 2 bytes for sensible + patterns that start (?i) but I don't think that matters. The use of (?i) is + just an example; this all applies to the other options as well. + + 4. Since libtool seems to echo the compile commands it is issuing, the output + from "make" can be reduced a bit by putting "@" in front of each libtool + compile command. + + 5. Patch from the folks at Google for configure.in to be a bit more thorough + in checking for a suitable C++ installation before trying to compile the + C++ stuff. This should fix a reported problem when a compiler was present, + but no suitable headers. + + 6. The man pages all had just "PCRE" as their title. I have changed them to + be the relevant file name. I have also arranged that these names are + retained in the file doc/pcre.txt, which is a concatenation in text format + of all the man pages except the little individual ones for each function. + + 7. The NON-UNIX-USE file had not been updated for the different set of source + files that come with release 6. I also added a few comments about the C++ + wrapper. + + +Version 6.0 07-Jun-05 +--------------------- + + 1. Some minor internal re-organization to help with my DFA experiments. + + 2. Some missing #ifdef SUPPORT_UCP conditionals in pcretest and printint that + didn't matter for the library itself when fully configured, but did matter + when compiling without UCP support, or within Exim, where the ucp files are + not imported. + + 3. Refactoring of the library code to split up the various functions into + different source modules. The addition of the new DFA matching code (see + below) to a single monolithic source would have made it really too + unwieldy, quite apart from causing all the code to be include in a + statically linked application, when only some functions are used. This is + relevant even without the DFA addition now that patterns can be compiled in + one application and matched in another. + + The downside of splitting up is that there have to be some external + functions and data tables that are used internally in different modules of + the library but which are not part of the API. These have all had their + names changed to start with "_pcre_" so that they are unlikely to clash + with other external names. + + 4. Added an alternate matching function, pcre_dfa_exec(), which matches using + a different (DFA) algorithm. Although it is slower than the original + function, it does have some advantages for certain types of matching + problem. + + 5. Upgrades to pcretest in order to test the features of pcre_dfa_exec(), + including restarting after a partial match. + + 6. A patch for pcregrep that defines INVALID_FILE_ATTRIBUTES if it is not + defined when compiling for Windows was sent to me. I have put it into the + code, though I have no means of testing or verifying it. + + 7. Added the pcre_refcount() auxiliary function. + + 8. Added the PCRE_FIRSTLINE option. This constrains an unanchored pattern to + match before or at the first newline in the subject string. In pcretest, + the /f option on a pattern can be used to set this. + + 9. A repeated \w when used in UTF-8 mode with characters greater than 256 + would behave wrongly. This has been present in PCRE since release 4.0. + +10. A number of changes to the pcregrep command: + + (a) Refactored how -x works; insert ^(...)$ instead of setting + PCRE_ANCHORED and checking the length, in preparation for adding + something similar for -w. + + (b) Added the -w (match as a word) option. + + (c) Refactored the way lines are read and buffered so as to have more + than one at a time available. + + (d) Implemented a pcregrep test script. + + (e) Added the -M (multiline match) option. This allows patterns to match + over several lines of the subject. The buffering ensures that at least + 8K, or the rest of the document (whichever is the shorter) is available + for matching (and similarly the previous 8K for lookbehind assertions). + + (f) Changed the --help output so that it now says + + -w, --word-regex(p) + + instead of two lines, one with "regex" and the other with "regexp" + because that confused at least one person since the short forms are the + same. (This required a bit of code, as the output is generated + automatically from a table. It wasn't just a text change.) + + (g) -- can be used to terminate pcregrep options if the next thing isn't an + option but starts with a hyphen. Could be a pattern or a path name + starting with a hyphen, for instance. + + (h) "-" can be given as a file name to represent stdin. + + (i) When file names are being printed, "(standard input)" is used for + the standard input, for compatibility with GNU grep. Previously + "<stdin>" was used. + + (j) The option --label=xxx can be used to supply a name to be used for + stdin when file names are being printed. There is no short form. + + (k) Re-factored the options decoding logic because we are going to add + two more options that take data. Such options can now be given in four + different ways, e.g. "-fname", "-f name", "--file=name", "--file name". + + (l) Added the -A, -B, and -C options for requesting that lines of context + around matches be printed. + + (m) Added the -L option to print the names of files that do not contain + any matching lines, that is, the complement of -l. + + (n) The return code is 2 if any file cannot be opened, but pcregrep does + continue to scan other files. + + (o) The -s option was incorrectly implemented. For compatibility with other + greps, it now suppresses the error message for a non-existent or non- + accessible file (but not the return code). There is a new option called + -q that suppresses the output of matching lines, which was what -s was + previously doing. + + (p) Added --include and --exclude options to specify files for inclusion + and exclusion when recursing. + +11. The Makefile was not using the Autoconf-supported LDFLAGS macro properly. + Hopefully, it now does. + +12. Missing cast in pcre_study(). + +13. Added an "uninstall" target to the makefile. + +14. Replaced "extern" in the function prototypes in Makefile.in with + "PCRE_DATA_SCOPE", which defaults to 'extern' or 'extern "C"' in the Unix + world, but is set differently for Windows. + +15. Added a second compiling function called pcre_compile2(). The only + difference is that it has an extra argument, which is a pointer to an + integer error code. When there is a compile-time failure, this is set + non-zero, in addition to the error test pointer being set to point to an + error message. The new argument may be NULL if no error number is required + (but then you may as well call pcre_compile(), which is now just a + wrapper). This facility is provided because some applications need a + numeric error indication, but it has also enabled me to tidy up the way + compile-time errors are handled in the POSIX wrapper. + +16. Added VPATH=.libs to the makefile; this should help when building with one + prefix path and installing with another. (Or so I'm told by someone who + knows more about this stuff than I do.) + +17. Added a new option, REG_DOTALL, to the POSIX function regcomp(). This + passes PCRE_DOTALL to the pcre_compile() function, making the "." character + match everything, including newlines. This is not POSIX-compatible, but + somebody wanted the feature. From pcretest it can be activated by using + both the P and the s flags. + +18. AC_PROG_LIBTOOL appeared twice in Makefile.in. Removed one. + +19. libpcre.pc was being incorrectly installed as executable. + +20. A couple of places in pcretest check for end-of-line by looking for '\n'; + it now also looks for '\r' so that it will work unmodified on Windows. + +21. Added Google's contributed C++ wrapper to the distribution. + +22. Added some untidy missing memory free() calls in pcretest, to keep + Electric Fence happy when testing. + + + +Version 5.0 13-Sep-04 +--------------------- + + 1. Internal change: literal characters are no longer packed up into items + containing multiple characters in a single byte-string. Each character + is now matched using a separate opcode. However, there may be more than one + byte in the character in UTF-8 mode. + + 2. The pcre_callout_block structure has two new fields: pattern_position and + next_item_length. These contain the offset in the pattern to the next match + item, and its length, respectively. + + 3. The PCRE_AUTO_CALLOUT option for pcre_compile() requests the automatic + insertion of callouts before each pattern item. Added the /C option to + pcretest to make use of this. + + 4. On the advice of a Windows user, the lines + + #if defined(_WIN32) || defined(WIN32) + _setmode( _fileno( stdout ), 0x8000 ); + #endif /* defined(_WIN32) || defined(WIN32) */ + + have been added to the source of pcretest. This apparently does useful + magic in relation to line terminators. + + 5. Changed "r" and "w" in the calls to fopen() in pcretest to "rb" and "wb" + for the benefit of those environments where the "b" makes a difference. + + 6. The icc compiler has the same options as gcc, but "configure" doesn't seem + to know about it. I have put a hack into configure.in that adds in code + to set GCC=yes if CC=icc. This seems to end up at a point in the + generated configure script that is early enough to affect the setting of + compiler options, which is what is needed, but I have no means of testing + whether it really works. (The user who reported this had patched the + generated configure script, which of course I cannot do.) + + LATER: After change 22 below (new libtool files), the configure script + seems to know about icc (and also ecc). Therefore, I have commented out + this hack in configure.in. + + 7. Added support for pkg-config (2 patches were sent in). + + 8. Negated POSIX character classes that used a combination of internal tables + were completely broken. These were [[:^alpha:]], [[:^alnum:]], and + [[:^ascii]]. Typically, they would match almost any characters. The other + POSIX classes were not broken in this way. + + 9. Matching the pattern "\b.*?" against "ab cd", starting at offset 1, failed + to find the match, as PCRE was deluded into thinking that the match had to + start at the start point or following a newline. The same bug applied to + patterns with negative forward assertions or any backward assertions + preceding ".*" at the start, unless the pattern required a fixed first + character. This was a failing pattern: "(?!.bcd).*". The bug is now fixed. + +10. In UTF-8 mode, when moving forwards in the subject after a failed match + starting at the last subject character, bytes beyond the end of the subject + string were read. + +11. Renamed the variable "class" as "classbits" to make life easier for C++ + users. (Previously there was a macro definition, but it apparently wasn't + enough.) + +12. Added the new field "tables" to the extra data so that tables can be passed + in at exec time, or the internal tables can be re-selected. This allows + a compiled regex to be saved and re-used at a later time by a different + program that might have everything at different addresses. + +13. Modified the pcre-config script so that, when run on Solaris, it shows a + -R library as well as a -L library. + +14. The debugging options of pcretest (-d on the command line or D on a + pattern) showed incorrect output for anything following an extended class + that contained multibyte characters and which was followed by a quantifier. + +15. Added optional support for general category Unicode character properties + via the \p, \P, and \X escapes. Unicode property support implies UTF-8 + support. It adds about 90K to the size of the library. The meanings of the + inbuilt class escapes such as \d and \s have NOT been changed. + +16. Updated pcredemo.c to include calls to free() to release the memory for the + compiled pattern. + +17. The generated file chartables.c was being created in the source directory + instead of in the building directory. This caused the build to fail if the + source directory was different from the building directory, and was + read-only. + +18. Added some sample Win commands from Mark Tetrode into the NON-UNIX-USE + file. No doubt somebody will tell me if they don't make sense... Also added + Dan Mooney's comments about building on OpenVMS. + +19. Added support for partial matching via the PCRE_PARTIAL option for + pcre_exec() and the \P data escape in pcretest. + +20. Extended pcretest with 3 new pattern features: + + (i) A pattern option of the form ">rest-of-line" causes pcretest to + write the compiled pattern to the file whose name is "rest-of-line". + This is a straight binary dump of the data, with the saved pointer to + the character tables forced to be NULL. The study data, if any, is + written too. After writing, pcretest reads a new pattern. + + (ii) If, instead of a pattern, "<rest-of-line" is given, pcretest reads a + compiled pattern from the given file. There must not be any + occurrences of "<" in the file name (pretty unlikely); if there are, + pcretest will instead treat the initial "<" as a pattern delimiter. + After reading in the pattern, pcretest goes on to read data lines as + usual. + + (iii) The F pattern option causes pcretest to flip the bytes in the 32-bit + and 16-bit fields in a compiled pattern, to simulate a pattern that + was compiled on a host of opposite endianness. + +21. The pcre-exec() function can now cope with patterns that were compiled on + hosts of opposite endianness, with this restriction: + + As for any compiled expression that is saved and used later, the tables + pointer field cannot be preserved; the extra_data field in the arguments + to pcre_exec() should be used to pass in a tables address if a value + other than the default internal tables were used at compile time. + +22. Calling pcre_exec() with a negative value of the "ovecsize" parameter is + now diagnosed as an error. Previously, most of the time, a negative number + would have been treated as zero, but if in addition "ovector" was passed as + NULL, a crash could occur. + +23. Updated the files ltmain.sh, config.sub, config.guess, and aclocal.m4 with + new versions from the libtool 1.5 distribution (the last one is a copy of + a file called libtool.m4). This seems to have fixed the need to patch + "configure" to support Darwin 1.3 (which I used to do). However, I still + had to patch ltmain.sh to ensure that ${SED} is set (it isn't on my + workstation). + +24. Changed the PCRE licence to be the more standard "BSD" licence. + + +Version 4.5 01-Dec-03 +--------------------- + + 1. There has been some re-arrangement of the code for the match() function so + that it can be compiled in a version that does not call itself recursively. + Instead, it keeps those local variables that need separate instances for + each "recursion" in a frame on the heap, and gets/frees frames whenever it + needs to "recurse". Keeping track of where control must go is done by means + of setjmp/longjmp. The whole thing is implemented by a set of macros that + hide most of the details from the main code, and operates only if + NO_RECURSE is defined while compiling pcre.c. If PCRE is built using the + "configure" mechanism, "--disable-stack-for-recursion" turns on this way of + operating. + + To make it easier for callers to provide specially tailored get/free + functions for this usage, two new functions, pcre_stack_malloc, and + pcre_stack_free, are used. They are always called in strict stacking order, + and the size of block requested is always the same. + + The PCRE_CONFIG_STACKRECURSE info parameter can be used to find out whether + PCRE has been compiled to use the stack or the heap for recursion. The + -C option of pcretest uses this to show which version is compiled. + + A new data escape \S, is added to pcretest; it causes the amounts of store + obtained and freed by both kinds of malloc/free at match time to be added + to the output. + + 2. Changed the locale test to use "fr_FR" instead of "fr" because that's + what's available on my current Linux desktop machine. + + 3. When matching a UTF-8 string, the test for a valid string at the start has + been extended. If start_offset is not zero, PCRE now checks that it points + to a byte that is the start of a UTF-8 character. If not, it returns + PCRE_ERROR_BADUTF8_OFFSET (-11). Note: the whole string is still checked; + this is necessary because there may be backward assertions in the pattern. + When matching the same subject several times, it may save resources to use + PCRE_NO_UTF8_CHECK on all but the first call if the string is long. + + 4. The code for checking the validity of UTF-8 strings has been tightened so + that it rejects (a) strings containing 0xfe or 0xff bytes and (b) strings + containing "overlong sequences". + + 5. Fixed a bug (appearing twice) that I could not find any way of exploiting! + I had written "if ((digitab[*p++] && chtab_digit) == 0)" where the "&&" + should have been "&", but it just so happened that all the cases this let + through by mistake were picked up later in the function. + + 6. I had used a variable called "isblank" - this is a C99 function, causing + some compilers to warn. To avoid this, I renamed it (as "blankclass"). + + 7. Cosmetic: (a) only output another newline at the end of pcretest if it is + prompting; (b) run "./pcretest /dev/null" at the start of the test script + so the version is shown; (c) stop "make test" echoing "./RunTest". + + 8. Added patches from David Burgess to enable PCRE to run on EBCDIC systems. + + 9. The prototype for memmove() for systems that don't have it was using + size_t, but the inclusion of the header that defines size_t was later. I've + moved the #includes for the C headers earlier to avoid this. + +10. Added some adjustments to the code to make it easier to compiler on certain + special systems: + + (a) Some "const" qualifiers were missing. + (b) Added the macro EXPORT before all exported functions; by default this + is defined to be empty. + (c) Changed the dftables auxiliary program (that builds chartables.c) so + that it reads its output file name as an argument instead of writing + to the standard output and assuming this can be redirected. + +11. In UTF-8 mode, if a recursive reference (e.g. (?1)) followed a character + class containing characters with values greater than 255, PCRE compilation + went into a loop. + +12. A recursive reference to a subpattern that was within another subpattern + that had a minimum quantifier of zero caused PCRE to crash. For example, + (x(y(?2))z)? provoked this bug with a subject that got as far as the + recursion. If the recursively-called subpattern itself had a zero repeat, + that was OK. + +13. In pcretest, the buffer for reading a data line was set at 30K, but the + buffer into which it was copied (for escape processing) was still set at + 1024, so long lines caused crashes. + +14. A pattern such as /[ab]{1,3}+/ failed to compile, giving the error + "internal error: code overflow...". This applied to any character class + that was followed by a possessive quantifier. + +15. Modified the Makefile to add libpcre.la as a prerequisite for + libpcreposix.la because I was told this is needed for a parallel build to + work. + +16. If a pattern that contained .* following optional items at the start was + studied, the wrong optimizing data was generated, leading to matching + errors. For example, studying /[ab]*.*c/ concluded, erroneously, that any + matching string must start with a or b or c. The correct conclusion for + this pattern is that a match can start with any character. + + +Version 4.4 13-Aug-03 +--------------------- + + 1. In UTF-8 mode, a character class containing characters with values between + 127 and 255 was not handled correctly if the compiled pattern was studied. + In fixing this, I have also improved the studying algorithm for such + classes (slightly). + + 2. Three internal functions had redundant arguments passed to them. Removal + might give a very teeny performance improvement. + + 3. Documentation bug: the value of the capture_top field in a callout is *one + more than* the number of the hightest numbered captured substring. + + 4. The Makefile linked pcretest and pcregrep with -lpcre, which could result + in incorrectly linking with a previously installed version. They now link + explicitly with libpcre.la. + + 5. configure.in no longer needs to recognize Cygwin specially. + + 6. A problem in pcre.in for Windows platforms is fixed. + + 7. If a pattern was successfully studied, and the -d (or /D) flag was given to + pcretest, it used to include the size of the study block as part of its + output. Unfortunately, the structure contains a field that has a different + size on different hardware architectures. This meant that the tests that + showed this size failed. As the block is currently always of a fixed size, + this information isn't actually particularly useful in pcretest output, so + I have just removed it. + + 8. Three pre-processor statements accidentally did not start in column 1. + Sadly, there are *still* compilers around that complain, even though + standard C has not required this for well over a decade. Sigh. + + 9. In pcretest, the code for checking callouts passed small integers in the + callout_data field, which is a void * field. However, some picky compilers + complained about the casts involved for this on 64-bit systems. Now + pcretest passes the address of the small integer instead, which should get + rid of the warnings. + +10. By default, when in UTF-8 mode, PCRE now checks for valid UTF-8 strings at + both compile and run time, and gives an error if an invalid UTF-8 sequence + is found. There is a option for disabling this check in cases where the + string is known to be correct and/or the maximum performance is wanted. + +11. In response to a bug report, I changed one line in Makefile.in from + + -Wl,--out-implib,.libs/lib@WIN_PREFIX@pcreposix.dll.a \ + to + -Wl,--out-implib,.libs/@WIN_PREFIX@libpcreposix.dll.a \ + + to look similar to other lines, but I have no way of telling whether this + is the right thing to do, as I do not use Windows. No doubt I'll get told + if it's wrong... + + +Version 4.3 21-May-03 +--------------------- + +1. Two instances of @WIN_PREFIX@ omitted from the Windows targets in the + Makefile. + +2. Some refactoring to improve the quality of the code: + + (i) The utf8_table... variables are now declared "const". + + (ii) The code for \cx, which used the "case flipping" table to upper case + lower case letters, now just substracts 32. This is ASCII-specific, + but the whole concept of \cx is ASCII-specific, so it seems + reasonable. + + (iii) PCRE was using its character types table to recognize decimal and + hexadecimal digits in the pattern. This is silly, because it handles + only 0-9, a-f, and A-F, but the character types table is locale- + specific, which means strange things might happen. A private + table is now used for this - though it costs 256 bytes, a table is + much faster than multiple explicit tests. Of course, the standard + character types table is still used for matching digits in subject + strings against \d. + + (iv) Strictly, the identifier ESC_t is reserved by POSIX (all identifiers + ending in _t are). So I've renamed it as ESC_tee. + +3. The first argument for regexec() in the POSIX wrapper should have been + defined as "const". + +4. Changed pcretest to use malloc() for its buffers so that they can be + Electric Fenced for debugging. + +5. There were several places in the code where, in UTF-8 mode, PCRE would try + to read one or more bytes before the start of the subject string. Often this + had no effect on PCRE's behaviour, but in some circumstances it could + provoke a segmentation fault. + +6. A lookbehind at the start of a pattern in UTF-8 mode could also cause PCRE + to try to read one or more bytes before the start of the subject string. + +7. A lookbehind in a pattern matched in non-UTF-8 mode on a PCRE compiled with + UTF-8 support could misbehave in various ways if the subject string + contained bytes with the 0x80 bit set and the 0x40 bit unset in a lookbehind + area. (PCRE was not checking for the UTF-8 mode flag, and trying to move + back over UTF-8 characters.) + + +Version 4.2 14-Apr-03 +--------------------- + +1. Typo "#if SUPPORT_UTF8" instead of "#ifdef SUPPORT_UTF8" fixed. + +2. Changes to the building process, supplied by Ronald Landheer-Cieslak + [ON_WINDOWS]: new variable, "#" on non-Windows platforms + [NOT_ON_WINDOWS]: new variable, "#" on Windows platforms + [WIN_PREFIX]: new variable, "cyg" for Cygwin + * Makefile.in: use autoconf substitution for OBJEXT, EXEEXT, BUILD_OBJEXT + and BUILD_EXEEXT + Note: automatic setting of the BUILD variables is not yet working + set CPPFLAGS and BUILD_CPPFLAGS (but don't use yet) - should be used at + compile-time but not at link-time + [LINK]: use for linking executables only + make different versions for Windows and non-Windows + [LINKLIB]: new variable, copy of UNIX-style LINK, used for linking + libraries + [LINK_FOR_BUILD]: new variable + [OBJEXT]: use throughout + [EXEEXT]: use throughout + <winshared>: new target + <wininstall>: new target + <dftables.o>: use native compiler + <dftables>: use native linker + <install>: handle Windows platform correctly + <clean>: ditto + <check>: ditto + copy DLL to top builddir before testing + + As part of these changes, -no-undefined was removed again. This was reported + to give trouble on HP-UX 11.0, so getting rid of it seems like a good idea + in any case. + +3. Some tidies to get rid of compiler warnings: + + . In the match_data structure, match_limit was an unsigned long int, whereas + match_call_count was an int. I've made them both unsigned long ints. + + . In pcretest the fact that a const uschar * doesn't automatically cast to + a void * provoked a warning. + + . Turning on some more compiler warnings threw up some "shadow" variables + and a few more missing casts. + +4. If PCRE was complied with UTF-8 support, but called without the PCRE_UTF8 + option, a class that contained a single character with a value between 128 + and 255 (e.g. /[\xFF]/) caused PCRE to crash. + +5. If PCRE was compiled with UTF-8 support, but called without the PCRE_UTF8 + option, a class that contained several characters, but with at least one + whose value was between 128 and 255 caused PCRE to crash. + + +Version 4.1 12-Mar-03 +--------------------- + +1. Compiling with gcc -pedantic found a couple of places where casts were +needed, and a string in dftables.c that was longer than standard compilers are +required to support. + +2. Compiling with Sun's compiler found a few more places where the code could +be tidied up in order to avoid warnings. + +3. The variables for cross-compiling were called HOST_CC and HOST_CFLAGS; the +first of these names is deprecated in the latest Autoconf in favour of the name +CC_FOR_BUILD, because "host" is typically used to mean the system on which the +compiled code will be run. I can't find a reference for HOST_CFLAGS, but by +analogy I have changed it to CFLAGS_FOR_BUILD. + +4. Added -no-undefined to the linking command in the Makefile, because this is +apparently helpful for Windows. To make it work, also added "-L. -lpcre" to the +linking step for the pcreposix library. + +5. PCRE was failing to diagnose the case of two named groups with the same +name. + +6. A problem with one of PCRE's optimizations was discovered. PCRE remembers a +literal character that is needed in the subject for a match, and scans along to +ensure that it is present before embarking on the full matching process. This +saves time in cases of nested unlimited repeats that are never going to match. +Problem: the scan can take a lot of time if the subject is very long (e.g. +megabytes), thus penalizing straightforward matches. It is now done only if the +amount of subject to be scanned is less than 1000 bytes. + +7. A lesser problem with the same optimization is that it was recording the +first character of an anchored pattern as "needed", thus provoking a search +right along the subject, even when the first match of the pattern was going to +fail. The "needed" character is now not set for anchored patterns, unless it +follows something in the pattern that is of non-fixed length. Thus, it still +fulfils its original purpose of finding quick non-matches in cases of nested +unlimited repeats, but isn't used for simple anchored patterns such as /^abc/. + + +Version 4.0 17-Feb-03 +--------------------- + +1. If a comment in an extended regex that started immediately after a meta-item +extended to the end of string, PCRE compiled incorrect data. This could lead to +all kinds of weird effects. Example: /#/ was bad; /()#/ was bad; /a#/ was not. + +2. Moved to autoconf 2.53 and libtool 1.4.2. + +3. Perl 5.8 no longer needs "use utf8" for doing UTF-8 things. Consequently, +the special perltest8 script is no longer needed - all the tests can be run +from a single perltest script. + +4. From 5.004, Perl has not included the VT character (0x0b) in the set defined +by \s. It has now been removed in PCRE. This means it isn't recognized as +whitespace in /x regexes too, which is the same as Perl. Note that the POSIX +class [:space:] *does* include VT, thereby creating a mess. + +5. Added the class [:blank:] (a GNU extension from Perl 5.8) to match only +space and tab. + +6. Perl 5.005 was a long time ago. It's time to amalgamate the tests that use +its new features into the main test script, reducing the number of scripts. + +7. Perl 5.8 has changed the meaning of patterns like /a(?i)b/. Earlier versions +were backward compatible, and made the (?i) apply to the whole pattern, as if +/i were given. Now it behaves more logically, and applies the option setting +only to what follows. PCRE has been changed to follow suit. However, if it +finds options settings right at the start of the pattern, it extracts them into +the global options, as before. Thus, they show up in the info data. + +8. Added support for the \Q...\E escape sequence. Characters in between are +treated as literals. This is slightly different from Perl in that $ and @ are +also handled as literals inside the quotes. In Perl, they will cause variable +interpolation. Note the following examples: + + Pattern PCRE matches Perl matches + + \Qabc$xyz\E abc$xyz abc followed by the contents of $xyz + \Qabc\$xyz\E abc\$xyz abc\$xyz + \Qabc\E\$\Qxyz\E abc$xyz abc$xyz + +For compatibility with Perl, \Q...\E sequences are recognized inside character +classes as well as outside them. + +9. Re-organized 3 code statements in pcretest to avoid "overflow in +floating-point constant arithmetic" warnings from a Microsoft compiler. Added a +(size_t) cast to one statement in pcretest and one in pcreposix to avoid +signed/unsigned warnings. + +10. SunOS4 doesn't have strtoul(). This was used only for unpicking the -o +option for pcretest, so I've replaced it by a simple function that does just +that job. + +11. pcregrep was ending with code 0 instead of 2 for the commands "pcregrep" or +"pcregrep -". + +12. Added "possessive quantifiers" ?+, *+, ++, and {,}+ which come from Sun's +Java package. This provides some syntactic sugar for simple cases of what my +documentation calls "once-only subpatterns". A pattern such as x*+ is the same +as (?>x*). In other words, if what is inside (?>...) is just a single repeated +item, you can use this simplified notation. Note that only makes sense with +greedy quantifiers. Consequently, the use of the possessive quantifier forces +greediness, whatever the setting of the PCRE_UNGREEDY option. + +13. A change of greediness default within a pattern was not taking effect at +the current level for patterns like /(b+(?U)a+)/. It did apply to parenthesized +subpatterns that followed. Patterns like /b+(?U)a+/ worked because the option +was abstracted outside. + +14. PCRE now supports the \G assertion. It is true when the current matching +position is at the start point of the match. This differs from \A when the +starting offset is non-zero. Used with the /g option of pcretest (or similar +code), it works in the same way as it does for Perl's /g option. If all +alternatives of a regex begin with \G, the expression is anchored to the start +match position, and the "anchored" flag is set in the compiled expression. + +15. Some bugs concerning the handling of certain option changes within patterns +have been fixed. These applied to options other than (?ims). For example, +"a(?x: b c )d" did not match "XabcdY" but did match "Xa b c dY". It should have +been the other way round. Some of this was related to change 7 above. + +16. PCRE now gives errors for /[.x.]/ and /[=x=]/ as unsupported POSIX +features, as Perl does. Previously, PCRE gave the warnings only for /[[.x.]]/ +and /[[=x=]]/. PCRE now also gives an error for /[:name:]/ because it supports +POSIX classes only within a class (e.g. /[[:alpha:]]/). + +17. Added support for Perl's \C escape. This matches one byte, even in UTF8 +mode. Unlike ".", it always matches newline, whatever the setting of +PCRE_DOTALL. However, PCRE does not permit \C to appear in lookbehind +assertions. Perl allows it, but it doesn't (in general) work because it can't +calculate the length of the lookbehind. At least, that's the case for Perl +5.8.0 - I've been told they are going to document that it doesn't work in +future. + +18. Added an error diagnosis for escapes that PCRE does not support: these are +\L, \l, \N, \P, \p, \U, \u, and \X. + +19. Although correctly diagnosing a missing ']' in a character class, PCRE was +reading past the end of the pattern in cases such as /[abcd/. + +20. PCRE was getting more memory than necessary for patterns with classes that +contained both POSIX named classes and other characters, e.g. /[[:space:]abc/. + +21. Added some code, conditional on #ifdef VPCOMPAT, to make life easier for +compiling PCRE for use with Virtual Pascal. + +22. Small fix to the Makefile to make it work properly if the build is done +outside the source tree. + +23. Added a new extension: a condition to go with recursion. If a conditional +subpattern starts with (?(R) the "true" branch is used if recursion has +happened, whereas the "false" branch is used only at the top level. + +24. When there was a very long string of literal characters (over 255 bytes +without UTF support, over 250 bytes with UTF support), the computation of how +much memory was required could be incorrect, leading to segfaults or other +strange effects. + +25. PCRE was incorrectly assuming anchoring (either to start of subject or to +start of line for a non-DOTALL pattern) when a pattern started with (.*) and +there was a subsequent back reference to those brackets. This meant that, for +example, /(.*)\d+\1/ failed to match "abc123bc". Unfortunately, it isn't +possible to check for precisely this case. All we can do is abandon the +optimization if .* occurs inside capturing brackets when there are any back +references whatsoever. (See below for a better fix that came later.) + +26. The handling of the optimization for finding the first character of a +non-anchored pattern, and for finding a character that is required later in the +match were failing in some cases. This didn't break the matching; it just +failed to optimize when it could. The way this is done has been re-implemented. + +27. Fixed typo in error message for invalid (?R item (it said "(?p"). + +28. Added a new feature that provides some of the functionality that Perl +provides with (?{...}). The facility is termed a "callout". The way it is done +in PCRE is for the caller to provide an optional function, by setting +pcre_callout to its entry point. Like pcre_malloc and pcre_free, this is a +global variable. By default it is unset, which disables all calling out. To get +the function called, the regex must include (?C) at appropriate points. This +is, in fact, equivalent to (?C0), and any number <= 255 may be given with (?C). +This provides a means of identifying different callout points. When PCRE +reaches such a point in the regex, if pcre_callout has been set, the external +function is called. It is provided with data in a structure called +pcre_callout_block, which is defined in pcre.h. If the function returns 0, +matching continues; if it returns a non-zero value, the match at the current +point fails. However, backtracking will occur if possible. [This was changed +later and other features added - see item 49 below.] + +29. pcretest is upgraded to test the callout functionality. It provides a +callout function that displays information. By default, it shows the start of +the match and the current position in the text. There are some new data escapes +to vary what happens: + + \C+ in addition, show current contents of captured substrings + \C- do not supply a callout function + \C!n return 1 when callout number n is reached + \C!n!m return 1 when callout number n is reached for the mth time + +30. If pcregrep was called with the -l option and just a single file name, it +output "<stdin>" if a match was found, instead of the file name. + +31. Improve the efficiency of the POSIX API to PCRE. If the number of capturing +slots is less than POSIX_MALLOC_THRESHOLD, use a block on the stack to pass to +pcre_exec(). This saves a malloc/free per call. The default value of +POSIX_MALLOC_THRESHOLD is 10; it can be changed by --with-posix-malloc-threshold +when configuring. + +32. The default maximum size of a compiled pattern is 64K. There have been a +few cases of people hitting this limit. The code now uses macros to handle the +storing of links as offsets within the compiled pattern. It defaults to 2-byte +links, but this can be changed to 3 or 4 bytes by --with-link-size when +configuring. Tests 2 and 5 work only with 2-byte links because they output +debugging information about compiled patterns. + +33. Internal code re-arrangements: + +(a) Moved the debugging function for printing out a compiled regex into + its own source file (printint.c) and used #include to pull it into + pcretest.c and, when DEBUG is defined, into pcre.c, instead of having two + separate copies. + +(b) Defined the list of op-code names for debugging as a macro in + internal.h so that it is next to the definition of the opcodes. + +(c) Defined a table of op-code lengths for simpler skipping along compiled + code. This is again a macro in internal.h so that it is next to the + definition of the opcodes. + +34. Added support for recursive calls to individual subpatterns, along the +lines of Robin Houston's patch (but implemented somewhat differently). + +35. Further mods to the Makefile to help Win32. Also, added code to pcregrep to +allow it to read and process whole directories in Win32. This code was +contributed by Lionel Fourquaux; it has not been tested by me. + +36. Added support for named subpatterns. The Python syntax (?P<name>...) is +used to name a group. Names consist of alphanumerics and underscores, and must +be unique. Back references use the syntax (?P=name) and recursive calls use +(?P>name) which is a PCRE extension to the Python extension. Groups still have +numbers. The function pcre_fullinfo() can be used after compilation to extract +a name/number map. There are three relevant calls: + + PCRE_INFO_NAMEENTRYSIZE yields the size of each entry in the map + PCRE_INFO_NAMECOUNT yields the number of entries + PCRE_INFO_NAMETABLE yields a pointer to the map. + +The map is a vector of fixed-size entries. The size of each entry depends on +the length of the longest name used. The first two bytes of each entry are the +group number, most significant byte first. There follows the corresponding +name, zero terminated. The names are in alphabetical order. + +37. Make the maximum literal string in the compiled code 250 for the non-UTF-8 +case instead of 255. Making it the same both with and without UTF-8 support +means that the same test output works with both. + +38. There was a case of malloc(0) in the POSIX testing code in pcretest. Avoid +calling malloc() with a zero argument. + +39. Change 25 above had to resort to a heavy-handed test for the .* anchoring +optimization. I've improved things by keeping a bitmap of backreferences with +numbers 1-31 so that if .* occurs inside capturing brackets that are not in +fact referenced, the optimization can be applied. It is unlikely that a +relevant occurrence of .* (i.e. one which might indicate anchoring or forcing +the match to follow \n) will appear inside brackets with a number greater than +31, but if it does, any back reference > 31 suppresses the optimization. + +40. Added a new compile-time option PCRE_NO_AUTO_CAPTURE. This has the effect +of disabling numbered capturing parentheses. Any opening parenthesis that is +not followed by ? behaves as if it were followed by ?: but named parentheses +can still be used for capturing (and they will acquire numbers in the usual +way). + +41. Redesigned the return codes from the match() function into yes/no/error so +that errors can be passed back from deep inside the nested calls. A malloc +failure while inside a recursive subpattern call now causes the +PCRE_ERROR_NOMEMORY return instead of quietly going wrong. + +42. It is now possible to set a limit on the number of times the match() +function is called in a call to pcre_exec(). This facility makes it possible to +limit the amount of recursion and backtracking, though not in a directly +obvious way, because the match() function is used in a number of different +circumstances. The count starts from zero for each position in the subject +string (for non-anchored patterns). The default limit is, for compatibility, a +large number, namely 10 000 000. You can change this in two ways: + +(a) When configuring PCRE before making, you can use --with-match-limit=n + to set a default value for the compiled library. + +(b) For each call to pcre_exec(), you can pass a pcre_extra block in which + a different value is set. See 45 below. + +If the limit is exceeded, pcre_exec() returns PCRE_ERROR_MATCHLIMIT. + +43. Added a new function pcre_config(int, void *) to enable run-time extraction +of things that can be changed at compile time. The first argument specifies +what is wanted and the second points to where the information is to be placed. +The current list of available information is: + + PCRE_CONFIG_UTF8 + +The output is an integer that is set to one if UTF-8 support is available; +otherwise it is set to zero. + + PCRE_CONFIG_NEWLINE + +The output is an integer that it set to the value of the code that is used for +newline. It is either LF (10) or CR (13). + + PCRE_CONFIG_LINK_SIZE + +The output is an integer that contains the number of bytes used for internal +linkage in compiled expressions. The value is 2, 3, or 4. See item 32 above. + + PCRE_CONFIG_POSIX_MALLOC_THRESHOLD + +The output is an integer that contains the threshold above which the POSIX +interface uses malloc() for output vectors. See item 31 above. + + PCRE_CONFIG_MATCH_LIMIT + +The output is an unsigned integer that contains the default limit of the number +of match() calls in a pcre_exec() execution. See 42 above. + +44. pcretest has been upgraded by the addition of the -C option. This causes it +to extract all the available output from the new pcre_config() function, and to +output it. The program then exits immediately. + +45. A need has arisen to pass over additional data with calls to pcre_exec() in +order to support additional features. One way would have been to define +pcre_exec2() (for example) with extra arguments, but this would not have been +extensible, and would also have required all calls to the original function to +be mapped to the new one. Instead, I have chosen to extend the mechanism that +is used for passing in "extra" data from pcre_study(). + +The pcre_extra structure is now exposed and defined in pcre.h. It currently +contains the following fields: + + flags a bitmap indicating which of the following fields are set + study_data opaque data from pcre_study() + match_limit a way of specifying a limit on match() calls for a specific + call to pcre_exec() + callout_data data for callouts (see 49 below) + +The flag bits are also defined in pcre.h, and are + + PCRE_EXTRA_STUDY_DATA + PCRE_EXTRA_MATCH_LIMIT + PCRE_EXTRA_CALLOUT_DATA + +The pcre_study() function now returns one of these new pcre_extra blocks, with +the actual study data pointed to by the study_data field, and the +PCRE_EXTRA_STUDY_DATA flag set. This can be passed directly to pcre_exec() as +before. That is, this change is entirely upwards-compatible and requires no +change to existing code. + +If you want to pass in additional data to pcre_exec(), you can either place it +in a pcre_extra block provided by pcre_study(), or create your own pcre_extra +block. + +46. pcretest has been extended to test the PCRE_EXTRA_MATCH_LIMIT feature. If a +data string contains the escape sequence \M, pcretest calls pcre_exec() several +times with different match limits, until it finds the minimum value needed for +pcre_exec() to complete. The value is then output. This can be instructive; for +most simple matches the number is quite small, but for pathological cases it +gets very large very quickly. + +47. There's a new option for pcre_fullinfo() called PCRE_INFO_STUDYSIZE. It +returns the size of the data block pointed to by the study_data field in a +pcre_extra block, that is, the value that was passed as the argument to +pcre_malloc() when PCRE was getting memory in which to place the information +created by pcre_study(). The fourth argument should point to a size_t variable. +pcretest has been extended so that this information is shown after a successful +pcre_study() call when information about the compiled regex is being displayed. + +48. Cosmetic change to Makefile: there's no need to have / after $(DESTDIR) +because what follows is always an absolute path. (Later: it turns out that this +is more than cosmetic for MinGW, because it doesn't like empty path +components.) + +49. Some changes have been made to the callout feature (see 28 above): + +(i) A callout function now has three choices for what it returns: + + 0 => success, carry on matching + > 0 => failure at this point, but backtrack if possible + < 0 => serious error, return this value from pcre_exec() + + Negative values should normally be chosen from the set of PCRE_ERROR_xxx + values. In particular, returning PCRE_ERROR_NOMATCH forces a standard + "match failed" error. The error number PCRE_ERROR_CALLOUT is reserved for + use by callout functions. It will never be used by PCRE itself. + +(ii) The pcre_extra structure (see 45 above) has a void * field called + callout_data, with corresponding flag bit PCRE_EXTRA_CALLOUT_DATA. The + pcre_callout_block structure has a field of the same name. The contents of + the field passed in the pcre_extra structure are passed to the callout + function in the corresponding field in the callout block. This makes it + easier to use the same callout-containing regex from multiple threads. For + testing, the pcretest program has a new data escape + + \C*n pass the number n (may be negative) as callout_data + + If the callout function in pcretest receives a non-zero value as + callout_data, it returns that value. + +50. Makefile wasn't handling CFLAGS properly when compiling dftables. Also, +there were some redundant $(CFLAGS) in commands that are now specified as +$(LINK), which already includes $(CFLAGS). + +51. Extensions to UTF-8 support are listed below. These all apply when (a) PCRE +has been compiled with UTF-8 support *and* pcre_compile() has been compiled +with the PCRE_UTF8 flag. Patterns that are compiled without that flag assume +one-byte characters throughout. Note that case-insensitive matching applies +only to characters whose values are less than 256. PCRE doesn't support the +notion of cases for higher-valued characters. + +(i) A character class whose characters are all within 0-255 is handled as + a bit map, and the map is inverted for negative classes. Previously, a + character > 255 always failed to match such a class; however it should + match if the class was a negative one (e.g. [^ab]). This has been fixed. + +(ii) A negated character class with a single character < 255 is coded as + "not this character" (OP_NOT). This wasn't working properly when the test + character was multibyte, either singly or repeated. + +(iii) Repeats of multibyte characters are now handled correctly in UTF-8 + mode, for example: \x{100}{2,3}. + +(iv) The character escapes \b, \B, \d, \D, \s, \S, \w, and \W (either + singly or repeated) now correctly test multibyte characters. However, + PCRE doesn't recognize any characters with values greater than 255 as + digits, spaces, or word characters. Such characters always match \D, \S, + and \W, and never match \d, \s, or \w. + +(v) Classes may now contain characters and character ranges with values + greater than 255. For example: [ab\x{100}-\x{400}]. + +(vi) pcregrep now has a --utf-8 option (synonym -u) which makes it call + PCRE in UTF-8 mode. + +52. The info request value PCRE_INFO_FIRSTCHAR has been renamed +PCRE_INFO_FIRSTBYTE because it is a byte value. However, the old name is +retained for backwards compatibility. (Note that LASTLITERAL is also a byte +value.) + +53. The single man page has become too large. I have therefore split it up into +a number of separate man pages. These also give rise to individual HTML pages; +these are now put in a separate directory, and there is an index.html page that +lists them all. Some hyperlinking between the pages has been installed. + +54. Added convenience functions for handling named capturing parentheses. + +55. Unknown escapes inside character classes (e.g. [\M]) and escapes that +aren't interpreted therein (e.g. [\C]) are literals in Perl. This is now also +true in PCRE, except when the PCRE_EXTENDED option is set, in which case they +are faulted. + +56. Introduced HOST_CC and HOST_CFLAGS which can be set in the environment when +calling configure. These values are used when compiling the dftables.c program +which is run to generate the source of the default character tables. They +default to the values of CC and CFLAGS. If you are cross-compiling PCRE, +you will need to set these values. + +57. Updated the building process for Windows DLL, as provided by Fred Cox. + + +Version 3.9 02-Jan-02 +--------------------- + +1. A bit of extraneous text had somehow crept into the pcregrep documentation. + +2. If --disable-static was given, the building process failed when trying to +build pcretest and pcregrep. (For some reason it was using libtool to compile +them, which is not right, as they aren't part of the library.) + + +Version 3.8 18-Dec-01 +--------------------- + +1. The experimental UTF-8 code was completely screwed up. It was packing the +bytes in the wrong order. How dumb can you get? + + +Version 3.7 29-Oct-01 +--------------------- + +1. In updating pcretest to check change 1 of version 3.6, I screwed up. +This caused pcretest, when used on the test data, to segfault. Unfortunately, +this didn't happen under Solaris 8, where I normally test things. + +2. The Makefile had to be changed to make it work on BSD systems, where 'make' +doesn't seem to recognize that ./xxx and xxx are the same file. (This entry +isn't in ChangeLog distributed with 3.7 because I forgot when I hastily made +this fix an hour or so after the initial 3.7 release.) + + +Version 3.6 23-Oct-01 +--------------------- + +1. Crashed with /(sens|respons)e and \1ibility/ and "sense and sensibility" if +offsets passed as NULL with zero offset count. + +2. The config.guess and config.sub files had not been updated when I moved to +the latest autoconf. + + +Version 3.5 15-Aug-01 +--------------------- + +1. Added some missing #if !defined NOPOSIX conditionals in pcretest.c that +had been forgotten. + +2. By using declared but undefined structures, we can avoid using "void" +definitions in pcre.h while keeping the internal definitions of the structures +private. + +3. The distribution is now built using autoconf 2.50 and libtool 1.4. From a +user point of view, this means that both static and shared libraries are built +by default, but this can be individually controlled. More of the work of +handling this static/shared cases is now inside libtool instead of PCRE's make +file. + +4. The pcretest utility is now installed along with pcregrep because it is +useful for users (to test regexs) and by doing this, it automatically gets +relinked by libtool. The documentation has been turned into a man page, so +there are now .1, .txt, and .html versions in /doc. + +5. Upgrades to pcregrep: + (i) Added long-form option names like gnu grep. + (ii) Added --help to list all options with an explanatory phrase. + (iii) Added -r, --recursive to recurse into sub-directories. + (iv) Added -f, --file to read patterns from a file. + +6. pcre_exec() was referring to its "code" argument before testing that +argument for NULL (and giving an error if it was NULL). + +7. Upgraded Makefile.in to allow for compiling in a different directory from +the source directory. + +8. Tiny buglet in pcretest: when pcre_fullinfo() was called to retrieve the +options bits, the pointer it was passed was to an int instead of to an unsigned +long int. This mattered only on 64-bit systems. + +9. Fixed typo (3.4/1) in pcre.h again. Sigh. I had changed pcre.h (which is +generated) instead of pcre.in, which it its source. Also made the same change +in several of the .c files. + +10. A new release of gcc defines printf() as a macro, which broke pcretest +because it had an ifdef in the middle of a string argument for printf(). Fixed +by using separate calls to printf(). + +11. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure +script, to force use of CR or LF instead of \n in the source. On non-Unix +systems, the value can be set in config.h. + +12. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an +absolute limit. Changed the text of the error message to make this clear, and +likewise updated the man page. + +13. The limit of 99 on the number of capturing subpatterns has been removed. +The new limit is 65535, which I hope will not be a "real" limit. + + +Version 3.4 22-Aug-00 +--------------------- + +1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *. + +2. Diagnose condition (?(0) as an error instead of crashing on matching. + + +Version 3.3 01-Aug-00 +--------------------- + +1. If an octal character was given, but the value was greater than \377, it +was not getting masked to the least significant bits, as documented. This could +lead to crashes in some systems. + +2. Perl 5.6 (if not earlier versions) accepts classes like [a-\d] and treats +the hyphen as a literal. PCRE used to give an error; it now behaves like Perl. + +3. Added the functions pcre_free_substring() and pcre_free_substring_list(). +These just pass their arguments on to (pcre_free)(), but they are provided +because some uses of PCRE bind it to non-C systems that can call its functions, +but cannot call free() or pcre_free() directly. + +4. Add "make test" as a synonym for "make check". Corrected some comments in +the Makefile. + +5. Add $(DESTDIR)/ in front of all the paths in the "install" target in the +Makefile. + +6. Changed the name of pgrep to pcregrep, because Solaris has introduced a +command called pgrep for grepping around the active processes. + +7. Added the beginnings of support for UTF-8 character strings. + +8. Arranged for the Makefile to pass over the settings of CC, CFLAGS, and +RANLIB to ./ltconfig so that they are used by libtool. I think these are all +the relevant ones. (AR is not passed because ./ltconfig does its own figuring +out for the ar command.) + + +Version 3.2 12-May-00 +--------------------- + +This is purely a bug fixing release. + +1. If the pattern /((Z)+|A)*/ was matched agained ZABCDEFG it matched Z instead +of ZA. This was just one example of several cases that could provoke this bug, +which was introduced by change 9 of version 2.00. The code for breaking +infinite loops after an iteration that matches an empty string was't working +correctly. + +2. The pcretest program was not imitating Perl correctly for the pattern /a*/g +when matched against abbab (for example). After matching an empty string, it +wasn't forcing anchoring when setting PCRE_NOTEMPTY for the next attempt; this +caused it to match further down the string than it should. + +3. The code contained an inclusion of sys/types.h. It isn't clear why this +was there because it doesn't seem to be needed, and it causes trouble on some +systems, as it is not a Standard C header. It has been removed. + +4. Made 4 silly changes to the source to avoid stupid compiler warnings that +were reported on the Macintosh. The changes were from + + while ((c = *(++ptr)) != 0 && c != '\n'); +to + while ((c = *(++ptr)) != 0 && c != '\n') ; + +Totally extraordinary, but if that's what it takes... + +5. PCRE is being used in one environment where neither memmove() nor bcopy() is +available. Added HAVE_BCOPY and an autoconf test for it; if neither +HAVE_MEMMOVE nor HAVE_BCOPY is set, use a built-in emulation function which +assumes the way PCRE uses memmove() (always moving upwards). + +6. PCRE is being used in one environment where strchr() is not available. There +was only one use in pcre.c, and writing it out to avoid strchr() probably gives +faster code anyway. + + +Version 3.1 09-Feb-00 +--------------------- + +The only change in this release is the fixing of some bugs in Makefile.in for +the "install" target: + +(1) It was failing to install pcreposix.h. + +(2) It was overwriting the pcre.3 man page with the pcreposix.3 man page. + + +Version 3.0 01-Feb-00 +--------------------- + +1. Add support for the /+ modifier to perltest (to output $` like it does in +pcretest). + +2. Add support for the /g modifier to perltest. + +3. Fix pcretest so that it behaves even more like Perl for /g when the pattern +matches null strings. + +4. Fix perltest so that it doesn't do unwanted things when fed an empty +pattern. Perl treats empty patterns specially - it reuses the most recent +pattern, which is not what we want. Replace // by /(?#)/ in order to avoid this +effect. + +5. The POSIX interface was broken in that it was just handing over the POSIX +captured string vector to pcre_exec(), but (since release 2.00) PCRE has +required a bigger vector, with some working space on the end. This means that +the POSIX wrapper now has to get and free some memory, and copy the results. + +6. Added some simple autoconf support, placing the test data and the +documentation in separate directories, re-organizing some of the +information files, and making it build pcre-config (a GNU standard). Also added +libtool support for building PCRE as a shared library, which is now the +default. + +7. Got rid of the leading zero in the definition of PCRE_MINOR because 08 and +09 are not valid octal constants. Single digits will be used for minor values +less than 10. + +8. Defined REG_EXTENDED and REG_NOSUB as zero in the POSIX header, so that +existing programs that set these in the POSIX interface can use PCRE without +modification. + +9. Added a new function, pcre_fullinfo() with an extensible interface. It can +return all that pcre_info() returns, plus additional data. The pcre_info() +function is retained for compatibility, but is considered to be obsolete. + +10. Added experimental recursion feature (?R) to handle one common case that +Perl 5.6 will be able to do with (?p{...}). + +11. Added support for POSIX character classes like [:alpha:], which Perl is +adopting. + + +Version 2.08 31-Aug-99 +---------------------- + +1. When startoffset was not zero and the pattern began with ".*", PCRE was not +trying to match at the startoffset position, but instead was moving forward to +the next newline as if a previous match had failed. + +2. pcretest was not making use of PCRE_NOTEMPTY when repeating for /g and /G, +and could get into a loop if a null string was matched other than at the start +of the subject. + +3. Added definitions of PCRE_MAJOR and PCRE_MINOR to pcre.h so the version can +be distinguished at compile time, and for completeness also added PCRE_DATE. + +5. Added Paul Sokolovsky's minor changes to make it easy to compile a Win32 DLL +in GnuWin32 environments. + + +Version 2.07 29-Jul-99 +---------------------- + +1. The documentation is now supplied in plain text form and HTML as well as in +the form of man page sources. + +2. C++ compilers don't like assigning (void *) values to other pointer types. +In particular this affects malloc(). Although there is no problem in Standard +C, I've put in casts to keep C++ compilers happy. + +3. Typo on pcretest.c; a cast of (unsigned char *) in the POSIX regexec() call +should be (const char *). + +4. If NOPOSIX is defined, pcretest.c compiles without POSIX support. This may +be useful for non-Unix systems who don't want to bother with the POSIX stuff. +However, I haven't made this a standard facility. The documentation doesn't +mention it, and the Makefile doesn't support it. + +5. The Makefile now contains an "install" target, with editable destinations at +the top of the file. The pcretest program is not installed. + +6. pgrep -V now gives the PCRE version number and date. + +7. Fixed bug: a zero repetition after a literal string (e.g. /abcde{0}/) was +causing the entire string to be ignored, instead of just the last character. + +8. If a pattern like /"([^\\"]+|\\.)*"/ is applied in the normal way to a +non-matching string, it can take a very, very long time, even for strings of +quite modest length, because of the nested recursion. PCRE now does better in +some of these cases. It does this by remembering the last required literal +character in the pattern, and pre-searching the subject to ensure it is present +before running the real match. In other words, it applies a heuristic to detect +some types of certain failure quickly, and in the above example, if presented +with a string that has no trailing " it gives "no match" very quickly. + +9. A new runtime option PCRE_NOTEMPTY causes null string matches to be ignored; +other alternatives are tried instead. + + +Version 2.06 09-Jun-99 +---------------------- + +1. Change pcretest's output for amount of store used to show just the code +space, because the remainder (the data block) varies in size between 32-bit and +64-bit systems. + +2. Added an extra argument to pcre_exec() to supply an offset in the subject to +start matching at. This allows lookbehinds to work when searching for multiple +occurrences in a string. + +3. Added additional options to pcretest for testing multiple occurrences: + + /+ outputs the rest of the string that follows a match + /g loops for multiple occurrences, using the new startoffset argument + /G loops for multiple occurrences by passing an incremented pointer + +4. PCRE wasn't doing the "first character" optimization for patterns starting +with \b or \B, though it was doing it for other lookbehind assertions. That is, +it wasn't noticing that a match for a pattern such as /\bxyz/ has to start with +the letter 'x'. On long subject strings, this gives a significant speed-up. + + +Version 2.05 21-Apr-99 +---------------------- + +1. Changed the type of magic_number from int to long int so that it works +properly on 16-bit systems. + +2. Fixed a bug which caused patterns starting with .* not to work correctly +when the subject string contained newline characters. PCRE was assuming +anchoring for such patterns in all cases, which is not correct because .* will +not pass a newline unless PCRE_DOTALL is set. It now assumes anchoring only if +DOTALL is set at top level; otherwise it knows that patterns starting with .* +must be retried after every newline in the subject. + + +Version 2.04 18-Feb-99 +---------------------- + +1. For parenthesized subpatterns with repeats whose minimum was zero, the +computation of the store needed to hold the pattern was incorrect (too large). +If such patterns were nested a few deep, this could multiply and become a real +problem. + +2. Added /M option to pcretest to show the memory requirement of a specific +pattern. Made -m a synonym of -s (which does this globally) for compatibility. + +3. Subpatterns of the form (regex){n,m} (i.e. limited maximum) were being +compiled in such a way that the backtracking after subsequent failure was +pessimal. Something like (a){0,3} was compiled as (a)?(a)?(a)? instead of +((a)((a)(a)?)?)? with disastrous performance if the maximum was of any size. + + +Version 2.03 02-Feb-99 +---------------------- + +1. Fixed typo and small mistake in man page. + +2. Added 4th condition (GPL supersedes if conflict) and created separate +LICENCE file containing the conditions. + +3. Updated pcretest so that patterns such as /abc\/def/ work like they do in +Perl, that is the internal \ allows the delimiter to be included in the +pattern. Locked out the use of \ as a delimiter. If \ immediately follows +the final delimiter, add \ to the end of the pattern (to test the error). + +4. Added the convenience functions for extracting substrings after a successful +match. Updated pcretest to make it able to test these functions. + + +Version 2.02 14-Jan-99 +---------------------- + +1. Initialized the working variables associated with each extraction so that +their saving and restoring doesn't refer to uninitialized store. + +2. Put dummy code into study.c in order to trick the optimizer of the IBM C +compiler for OS/2 into generating correct code. Apparently IBM isn't going to +fix the problem. + +3. Pcretest: the timing code wasn't using LOOPREPEAT for timing execution +calls, and wasn't printing the correct value for compiling calls. Increased the +default value of LOOPREPEAT, and the number of significant figures in the +times. + +4. Changed "/bin/rm" in the Makefile to "-rm" so it works on Windows NT. + +5. Renamed "deftables" as "dftables" to get it down to 8 characters, to avoid +a building problem on Windows NT with a FAT file system. + + +Version 2.01 21-Oct-98 +---------------------- + +1. Changed the API for pcre_compile() to allow for the provision of a pointer +to character tables built by pcre_maketables() in the current locale. If NULL +is passed, the default tables are used. + + +Version 2.00 24-Sep-98 +---------------------- + +1. Since the (>?) facility is in Perl 5.005, don't require PCRE_EXTRA to enable +it any more. + +2. Allow quantification of (?>) groups, and make it work correctly. + +3. The first character computation wasn't working for (?>) groups. + +4. Correct the implementation of \Z (it is permitted to match on the \n at the +end of the subject) and add 5.005's \z, which really does match only at the +very end of the subject. + +5. Remove the \X "cut" facility; Perl doesn't have it, and (?> is neater. + +6. Remove the ability to specify CASELESS, MULTILINE, DOTALL, and +DOLLAR_END_ONLY at runtime, to make it possible to implement the Perl 5.005 +localized options. All options to pcre_study() were also removed. + +7. Add other new features from 5.005: + + $(?<= positive lookbehind + $(?<! negative lookbehind + (?imsx-imsx) added the unsetting capability + such a setting is global if at outer level; local otherwise + (?imsx-imsx:) non-capturing groups with option setting + (?(cond)re|re) conditional pattern matching + + A backreference to itself in a repeated group matches the previous + captured string. + +8. General tidying up of studying (both automatic and via "study") +consequential on the addition of new assertions. + +9. As in 5.005, unlimited repeated groups that could match an empty substring +are no longer faulted at compile time. Instead, the loop is forcibly broken at +runtime if any iteration does actually match an empty substring. + +10. Include the RunTest script in the distribution. + +11. Added tests from the Perl 5.005_02 distribution. This showed up a few +discrepancies, some of which were old and were also with respect to 5.004. They +have now been fixed. + + +Version 1.09 28-Apr-98 +---------------------- + +1. A negated single character class followed by a quantifier with a minimum +value of one (e.g. [^x]{1,6} ) was not compiled correctly. This could lead to +program crashes, or just wrong answers. This did not apply to negated classes +containing more than one character, or to minima other than one. + + +Version 1.08 27-Mar-98 +---------------------- + +1. Add PCRE_UNGREEDY to invert the greediness of quantifiers. + +2. Add (?U) and (?X) to set PCRE_UNGREEDY and PCRE_EXTRA respectively. The +latter must appear before anything that relies on it in the pattern. + + +Version 1.07 16-Feb-98 +---------------------- + +1. A pattern such as /((a)*)*/ was not being diagnosed as in error (unlimited +repeat of a potentially empty string). + + +Version 1.06 23-Jan-98 +---------------------- + +1. Added Markus Oberhumer's little patches for C++. + +2. Literal strings longer than 255 characters were broken. + + +Version 1.05 23-Dec-97 +---------------------- + +1. Negated character classes containing more than one character were failing if +PCRE_CASELESS was set at run time. + + +Version 1.04 19-Dec-97 +---------------------- + +1. Corrected the man page, where some "const" qualifiers had been omitted. + +2. Made debugging output print "{0,xxx}" instead of just "{,xxx}" to agree with +input syntax. + +3. Fixed memory leak which occurred when a regex with back references was +matched with an offsets vector that wasn't big enough. The temporary memory +that is used in this case wasn't being freed if the match failed. + +4. Tidied pcretest to ensure it frees memory that it gets. + +5. Temporary memory was being obtained in the case where the passed offsets +vector was exactly big enough. + +6. Corrected definition of offsetof() from change 5 below. + +7. I had screwed up change 6 below and broken the rules for the use of +setjmp(). Now fixed. + + +Version 1.03 18-Dec-97 +---------------------- + +1. A erroneous regex with a missing opening parenthesis was correctly +diagnosed, but PCRE attempted to access brastack[-1], which could cause crashes +on some systems. + +2. Replaced offsetof(real_pcre, code) by offsetof(real_pcre, code[0]) because +it was reported that one broken compiler failed on the former because "code" is +also an independent variable. + +3. The erroneous regex a[]b caused an array overrun reference. + +4. A regex ending with a one-character negative class (e.g. /[^k]$/) did not +fail on data ending with that character. (It was going on too far, and checking +the next character, typically a binary zero.) This was specific to the +optimized code for single-character negative classes. + +5. Added a contributed patch from the TIN world which does the following: + + + Add an undef for memmove, in case the the system defines a macro for it. + + + Add a definition of offsetof(), in case there isn't one. (I don't know + the reason behind this - offsetof() is part of the ANSI standard - but + it does no harm). + + + Reduce the ifdef's in pcre.c using macro DPRINTF, thereby eliminating + most of the places where whitespace preceded '#'. I have given up and + allowed the remaining 2 cases to be at the margin. + + + Rename some variables in pcre to eliminate shadowing. This seems very + pedantic, but does no harm, of course. + +6. Moved the call to setjmp() into its own function, to get rid of warnings +from gcc -Wall, and avoided calling it at all unless PCRE_EXTRA is used. + +7. Constructs such as \d{8,} were compiling into the equivalent of +\d{8}\d{0,65527} instead of \d{8}\d* which didn't make much difference to the +outcome, but in this particular case used more store than had been allocated, +which caused the bug to be discovered because it threw up an internal error. + +8. The debugging code in both pcre and pcretest for outputting the compiled +form of a regex was going wrong in the case of back references followed by +curly-bracketed repeats. + + +Version 1.02 12-Dec-97 +---------------------- + +1. Typos in pcre.3 and comments in the source fixed. + +2. Applied a contributed patch to get rid of places where it used to remove +'const' from variables, and fixed some signed/unsigned and uninitialized +variable warnings. + +3. Added the "runtest" target to Makefile. + +4. Set default compiler flag to -O2 rather than just -O. + + +Version 1.01 19-Nov-97 +---------------------- + +1. PCRE was failing to diagnose unlimited repeat of empty string for patterns +like /([ab]*)*/, that is, for classes with more than one character in them. + +2. Likewise, it wasn't diagnosing patterns with "once-only" subpatterns, such +as /((?>a*))*/ (a PCRE_EXTRA facility). + + +Version 1.00 18-Nov-97 +---------------------- + +1. Added compile-time macros to support systems such as SunOS4 which don't have +memmove() or strerror() but have other things that can be used instead. + +2. Arranged that "make clean" removes the executables. + + +Version 0.99 27-Oct-97 +---------------------- + +1. Fixed bug in code for optimizing classes with only one character. It was +initializing a 32-byte map regardless, which could cause it to run off the end +of the memory it had got. + +2. Added, conditional on PCRE_EXTRA, the proposed (?>REGEX) construction. + + +Version 0.98 22-Oct-97 +---------------------- + +1. Fixed bug in code for handling temporary memory usage when there are more +back references than supplied space in the ovector. This could cause segfaults. + + +Version 0.97 21-Oct-97 +---------------------- + +1. Added the \X "cut" facility, conditional on PCRE_EXTRA. + +2. Optimized negated single characters not to use a bit map. + +3. Brought error texts together as macro definitions; clarified some of them; +fixed one that was wrong - it said "range out of order" when it meant "invalid +escape sequence". + +4. Changed some char * arguments to const char *. + +5. Added PCRE_NOTBOL and PCRE_NOTEOL (from POSIX). + +6. Added the POSIX-style API wrapper in pcreposix.a and testing facilities in +pcretest. + + +Version 0.96 16-Oct-97 +---------------------- + +1. Added a simple "pgrep" utility to the distribution. + +2. Fixed an incompatibility with Perl: "{" is now treated as a normal character +unless it appears in one of the precise forms "{ddd}", "{ddd,}", or "{ddd,ddd}" +where "ddd" means "one or more decimal digits". + +3. Fixed serious bug. If a pattern had a back reference, but the call to +pcre_exec() didn't supply a large enough ovector to record the related +identifying subpattern, the match always failed. PCRE now remembers the number +of the largest back reference, and gets some temporary memory in which to save +the offsets during matching if necessary, in order to ensure that +backreferences always work. + +4. Increased the compatibility with Perl in a number of ways: + + (a) . no longer matches \n by default; an option PCRE_DOTALL is provided + to request this handling. The option can be set at compile or exec time. + + (b) $ matches before a terminating newline by default; an option + PCRE_DOLLAR_ENDONLY is provided to override this (but not in multiline + mode). The option can be set at compile or exec time. + + (c) The handling of \ followed by a digit other than 0 is now supposed to be + the same as Perl's. If the decimal number it represents is less than 10 + or there aren't that many previous left capturing parentheses, an octal + escape is read. Inside a character class, it's always an octal escape, + even if it is a single digit. + + (d) An escaped but undefined alphabetic character is taken as a literal, + unless PCRE_EXTRA is set. Currently this just reserves the remaining + escapes. + + (e) {0} is now permitted. (The previous item is removed from the compiled + pattern). + +5. Changed all the names of code files so that the basic parts are no longer +than 10 characters, and abolished the teeny "globals.c" file. + +6. Changed the handling of character classes; they are now done with a 32-byte +bit map always. + +7. Added the -d and /D options to pcretest to make it possible to look at the +internals of compilation without having to recompile pcre. + + +Version 0.95 23-Sep-97 +---------------------- + +1. Fixed bug in pre-pass concerning escaped "normal" characters such as \x5c or +\x20 at the start of a run of normal characters. These were being treated as +real characters, instead of the source characters being re-checked. + + +Version 0.94 18-Sep-97 +---------------------- + +1. The functions are now thread-safe, with the caveat that the global variables +containing pointers to malloc() and free() or alternative functions are the +same for all threads. + +2. Get pcre_study() to generate a bitmap of initial characters for non- +anchored patterns when this is possible, and use it if passed to pcre_exec(). + + +Version 0.93 15-Sep-97 +---------------------- + +1. /(b)|(:+)/ was computing an incorrect first character. + +2. Add pcre_study() to the API and the passing of pcre_extra to pcre_exec(), +but not actually doing anything yet. + +3. Treat "-" characters in classes that cannot be part of ranges as literals, +as Perl does (e.g. [-az] or [az-]). + +4. Set the anchored flag if a branch starts with .* or .*? because that tests +all possible positions. + +5. Split up into different modules to avoid including unneeded functions in a +compiled binary. However, compile and exec are still in one module. The "study" +function is split off. + +6. The character tables are now in a separate module whose source is generated +by an auxiliary program - but can then be edited by hand if required. There are +now no calls to isalnum(), isspace(), isdigit(), isxdigit(), tolower() or +toupper() in the code. + +7. Turn the malloc/free funtions variables into pcre_malloc and pcre_free and +make them global. Abolish the function for setting them, as the caller can now +set them directly. + + +Version 0.92 11-Sep-97 +---------------------- + +1. A repeat with a fixed maximum and a minimum of 1 for an ordinary character +(e.g. /a{1,3}/) was broken (I mis-optimized it). + +2. Caseless matching was not working in character classes if the characters in +the pattern were in upper case. + +3. Make ranges like [W-c] work in the same way as Perl for caseless matching. + +4. Make PCRE_ANCHORED public and accept as a compile option. + +5. Add an options word to pcre_exec() and accept PCRE_ANCHORED and +PCRE_CASELESS at run time. Add escapes \A and \I to pcretest to cause it to +pass them. + +6. Give an error if bad option bits passed at compile or run time. + +7. Add PCRE_MULTILINE at compile and exec time, and (?m) as well. Add \M to +pcretest to cause it to pass that flag. + +8. Add pcre_info(), to get the number of identifying subpatterns, the stored +options, and the first character, if set. + +9. Recognize C+ or C{n,m} where n >= 1 as providing a fixed starting character. + + +Version 0.91 10-Sep-97 +---------------------- + +1. PCRE was failing to diagnose unlimited repeats of subpatterns that could +match the empty string as in /(a*)*/. It was looping and ultimately crashing. + +2. PCRE was looping on encountering an indefinitely repeated back reference to +a subpattern that had matched an empty string, e.g. /(a|)\1*/. It now does what +Perl does - treats the match as successful. + +**** Added: freeswitch/trunk/libs/pcre/INSTALL ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/INSTALL Tue Dec 19 14:54:26 2006 @@ -0,0 +1,185 @@ +Basic Installation +================== + + These are generic installation instructions that apply to systems that +can run the `configure' shell script - Unix systems and any that imitate +it.

Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not supports the `VPATH' +variable, you have to compile the package for one architecture at a time +in the source code directory. After you have installed the package for +one architecture, use `make distclean' before reconfiguring for another +architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options.

+1,266 @@ +News about PCRE releases +------------------------ + +Release 6.7 04-Jul-06 +--------------------- + +The main additions to this release are the ability to use the same name for +multiple sets of parentheses, and support for CRLF line endings in both the +library and pcregrep (and in pcretest for testing). + +Thanks to Ian Taylor, the stack usage for many kinds of pattern has been +significantly reduced for certain subject strings. + + +Release 6.5 01-Feb-06 +--------------------- + +Important changes in this release: + +1. A number of new features have been added to pcregrep. + +2. The Unicode property tables have been updated to Unicode 4.1.0, and the + supported properties have been extended with script names such as "Arabic", + and the derived properties "Any" and "L&". This has necessitated a change to + the interal format of compiled patterns. Any saved compiled patterns that + use \p or \P must be recompiled. + +3. The specification of recursion in patterns has been changed so that all + recursive subpatterns are automatically treated as atomic groups. Thus, for + example, (?R) is treated as if it were (?>(?R)). This is necessary because + otherwise there are situations where recursion does not work. + +See the ChangeLog for a complete list of changes, which include a number of bug +fixes and tidies. + + +Release 6.0 07-Jun-05 +--------------------- + +The release number has been increased to 6.0 because of the addition of several +major new pieces of functionality. + +A new function, pcre_dfa_exec(), which implements pattern matching using a DFA +algorithm, has been added. This has a number of advantages for certain cases, +though it does run more slowly, and lacks the ability to capture substrings. On +the other hand, it does find all matches, not just the first, and it works +better for partial matching. The pcrematching man page discusses the +differences. + +The pcretest program has been enhanced so that it can make use of the new +pcre_dfa_exec() matching function and the extra features it provides. + +The distribution now includes a C++ wrapper library. This is built +automatically if a C++ compiler is found. The pcrecpp man page discusses this +interface. + +The code itself has been re-organized into many more files, one for each +function, so it no longer requires everything to be linked in when static +linkage is used. As a consequence, some internal functions have had to have +their names exposed. These functions all have names starting with _pcre_. They +are undocumented, and are not intended for use by outside callers. + +The pcregrep program has been enhanced with new functionality such as +multiline-matching and options for output more matching context. See the +ChangeLog for a complete list of changes to the library and the utility +programs. + + +Release 5.0 13-Sep-04 +--------------------- + +The licence under which PCRE is released has been changed to the more +conventional "BSD" licence. + +In the code, some bugs have been fixed, and there are also some major changes +in this release (which is why I've increased the number to 5.0). Some changes +are internal rearrangements, and some provide a number of new facilities. The +new features are: + +1. There's an "automatic callout" feature that inserts callouts before every + item in the regex, and there's a new callout field that gives the position + in the pattern - useful for debugging and tracing. + +2. The extra_data structure can now be used to pass in a set of character + tables at exec time. This is useful if compiled regex are saved and re-used + at a later time when the tables may not be at the same address. If the + default internal tables are used, the pointer saved with the compiled + pattern is now set to NULL, which means that you don't need to do anything + special unless you are using custom tables. + +3. It is possible, with some restrictions on the content of the regex, to + request "partial" matching. A special return code is given if all of the + subject string matched part of the regex. This could be useful for testing + an input field as it is being typed. + +4. There is now some optional support for Unicode character properties, which + means that the patterns items such as \p{Lu} and \X can now be used. Only + the general category properties are supported. If PCRE is compiled with this + support, an additional 90K data structure is include, which increases the + size of the library dramatically. + +5. There is support for saving compiled patterns and re-using them later. + +6. There is support for running regular expressions that were compiled on a + different host with the opposite endianness. + +7. The pcretest program has been extended to accommodate the new features. + +The main internal rearrangement is that sequences of literal characters are no +longer handled as strings. Instead, each character is handled on its own. This +makes some UTF-8 handling easier, and makes the support of partial matching +possible. Compiled patterns containing long literal strings will be larger as a +result of this change; I hope that performance will not be much affected. + + +Release 4.5 01-Dec-03 +--------------------- + +Again mainly a bug-fix and tidying release, with only a couple of new features: + +1. It's possible now to compile PCRE so that it does not use recursive +function calls when matching. Instead it gets memory from the heap. This slows +things down, but may be necessary on systems with limited stacks. + +2. UTF-8 string checking has been tightened to reject overlong sequences and to +check that a starting offset points to the start of a character. Failure of the +latter returns a new error code: PCRE_ERROR_BADUTF8_OFFSET. + +3. PCRE can now be compiled for systems that use EBCDIC code. + + +Release 4.4 21-Aug-03 +--------------------- + +This is mainly a bug-fix and tidying release. The only new feature is that PCRE +checks UTF-8 strings for validity by default. There is an option to suppress +this, just in case anybody wants that teeny extra bit of performance. + + +Releases 4.1 - 4.3 +------------------ + +Sorry, I forgot about updating the NEWS file for these releases. Please take a +look at ChangeLog. + + +Release 4.0 17-Feb-03 +--------------------- + +There have been a lot of changes for the 4.0 release, adding additional +functionality and mending bugs. Below is a list of the highlights of the new +functionality. For full details of these features, please consult the +documentation. For a complete list of changes, see the ChangeLog file. + +1. Support for Perl's \Q...\E escapes. + +2. "Possessive quantifiers" ?+, *+, ++, and {,}+ which come from Sun's Java +package. They provide some syntactic sugar for simple cases of "atomic +grouping". + +3. Support for the \G assertion. It is true when the current matching position +is at the start point of the match. + +4. A new feature that provides some of the functionality that Perl provides +with (?{...}). The facility is termed a "callout". The way it is done in PCRE +is for the caller to provide an optional function, by setting pcre_callout to +its entry point. To get the function called, the regex must include (?C) at +appropriate points. + +5. Support for recursive calls to individual subpatterns. This makes it really +easy to get totally confused. + +6. Support for named subpatterns. The Python syntax (?P<name>...) is used to +name a group. + +7. Several extensions to UTF-8 support; it is now fairly complete. There is an +option for pcregrep to make it operate in UTF-8 mode. + +8. The single man page has been split into a number of separate man pages. +These also give rise to individual HTML pages which are put in a separate +directory. There is an index.html page that lists them all. Some hyperlinking +between the pages has been installed. + + +Release 3.5 15-Aug-01 +--------------------- + +1. The configuring system has been upgraded to use later versions of autoconf +and libtool. By default it builds both a shared and a static library if the OS +supports it. You can use --disable-shared or --disable-static on the configure +command if you want only one of them. + +2. The pcretest utility is now installed along with pcregrep because it is +useful for users (to test regexs) and by doing this, it automatically gets +relinked by libtool. The documentation has been turned into a man page, so +there are now .1, .txt, and .html versions in /doc. + +3. Upgrades to pcregrep: + (i) Added long-form option names like gnu grep. + (ii) Added --help to list all options with an explanatory phrase. + (iii) Added -r, --recursive to recurse into sub-directories. + (iv) Added -f, --file to read patterns from a file. + +4. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure +script, to force use of CR or LF instead of \n in the source. On non-Unix +systems, the value can be set in config.h. + +5. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an +absolute limit. Changed the text of the error message to make this clear, and +likewise updated the man page. + +6. The limit of 99 on the number of capturing subpatterns has been removed. +The new limit is 65535, which I hope will not be a "real" limit. + + +Release 3.3 01-Aug-00 +--------------------- + +There is some support for UTF-8 character strings. This is incomplete and +experimental. The documentation describes what is and what is not implemented. +Otherwise, this is just a bug-fixing release. + + +Release 3.0 01-Feb-00 +--------------------- + +1. A "configure" script is now used to configure PCRE for Unix systems. It +builds a Makefile, a config.h file, and the pcre-config script. + +2. PCRE is built as a shared library by default. + +3. There is support for POSIX classes such as [:alpha:]. + +5. There is an experimental recursion feature. + +---------------------------------------------------------------------------- + IMPORTANT FOR THOSE UPGRADING FROM VERSIONS BEFORE 2.00 + +Please note that there has been a change in the API such that a larger +ovector is required at matching time, to provide some additional workspace. +The new man page has details. This change was necessary in order to support +some of the new functionality in Perl 5.005. + + IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.00 + +Another (I hope this is the last!) change has been made to the API for the +pcre_compile() function. An additional argument has been added to make it +possible to pass over a pointer to character tables built in the current +locale by pcre_maketables(). To use the default tables, this new arguement +should be passed as NULL. + + IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.05 + +Yet another (and again I hope this really is the last) change has been made +to the API for the pcre_exec() function.

These environments are Mingw32 +(http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and CygWin +(http://sourceware.cygnus.com/cygwin/). Paul comments: + + For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get + pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically + linked pgrep and pcretest. If you have /bin/sh, run RunTest (three + main test go ok, locale not supported). + +Changes to do MinGW with autoconf 2.50 were supplied by Fred Cox +<sailorFred@yahoo.com>, who comments as follows: + + If you are using the PCRE DLL, the normal Unix style configure && make && + make check && make install should just work[*]. If you want to statically + link against the .a file, you must define PCRE_STATIC before including + pcre.h, otherwise the pcre_malloc and pcre_free exported functions will be + declared __declspec(dllimport), with hilarious results. See the configure.in + and pcretest.c for how it is done for the static test. + + Also, there will only be a libpcre.la, not a libpcreposix.la, as you + would expect from the Unix version. The single DLL includes the pcreposix + interface. + +[*] But note that the supplied test files are in Unix format, with just LF +characters as line terminators. You will have to edit them to change to CR LF +terminators. + +A script for building PCRE using Borland's C++ compiler for use with VPASCAL +was contributed by Alexander Tokarev.

The distribution now includes a +set of C++ wrapper functions, courtesy of Google Inc. (see the pcrecpp man page +for details). + +Also included are a set of C wrapper functions that are based on the POSIX +API. These end up in the library called libpcreposix. Note that this just +provides a POSIX calling interface to PCRE: the regular expressions themselves +still follow Perl syntax and semantics. The header file for the POSIX-style +functions is called pcreposix.h. The official POSIX name is regex.h, but I +didn't want to risk possible problems with existing files of that name by +distributing it that way. To use it with an existing program that uses the +POSIX API, it will have to be renamed or pointed at by a link. + +If you are using the POSIX interface to PCRE and there is already a POSIX regex +library installed on your system, you must take care when linking programs to +ensure that they link with PCRE's libpcreposix library. Otherwise they may pick +up the "real" POSIX functions of the same name. + + +Documentation for PCRE +---------------------- + +If you install PCRE in the normal way, you will end up with an installed set of +man pages whose names all start with "pcre". The one that is just called "pcre" +lists all the others. In addition to these man pages, the PCRE documentation is +supplied in two other forms; however, as there is no standard place to install +them, they are left in the doc directory of the unpacked source distribution. +These forms are: + + 1. Files called doc/pcre.txt, doc/pcregrep.txt, and doc/pcretest.txt. The + first of these is a concatenation of the text forms of all the section 3 + man pages except those that summarize individual functions. The other two + are the text forms of the section 1 man pages for the pcregrep and + pcretest commands. Text forms are provided for ease of scanning with text + editors or similar tools. + + 2. A subdirectory called doc/html contains all the documentation in HTML + form, hyperlinked in various ways, and rooted in a file called + doc/index.html. + + +Contributions by users of PCRE +------------------------------ + +You can find contributions from PCRE users in the directory + + ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib + +where there is also a README file giving brief descriptions of what they are. +Several of them provide support for compiling PCRE on various flavours of +Windows systems (I myself do not use Windows). Some are complete in themselves; +others are pointers to URLs containing relevant files. + + +Building PCRE on a Unix-like system +----------------------------------- + +If you are using HP's ANSI C++ compiler (aCC), please see the special note +in the section entitled "Using HP's ANSI C++ compiler (aCC)" below. + +To build PCRE on a Unix-like system, first run the "configure" command from the +PCRE distribution directory, with your current directory set to the directory +where you want the files to be created. This command is a standard GNU +"autoconf" configuration script, for which generic instructions are supplied in +INSTALL. + +Most commonly, people build PCRE within its own distribution directory, and in +this case, on many systems, just running "./configure" is sufficient, but the +usual methods of changing standard defaults are available. For example: + +CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local + +specifies that the C compiler should be run with the flags '-O2 -Wall' instead +of the default, and that "make install" should install PCRE under /opt/local +instead of the default /usr/local. + +If you want to build in a different directory, just run "configure" with that +directory as current. For example, suppose you have unpacked the PCRE source +into /source/pcre/pcre-xxx, but you want to build it in /build/pcre/pcre-xxx: + +cd /build/pcre/pcre-xxx +/source/pcre/pcre-xxx/configure + +PCRE is written in C and is normally compiled as a C library. However, it is +possible to build it as a C++ library, though the provided building apparatus +does not have any features to support this. + +There are some optional features that can be included or omitted from the PCRE +library. You can read more about them in the pcrebuild man page. + +. If you want to suppress the building of the C++ wrapper library, you can add + --disable-cpp to the "configure" command. Otherwise, when "configure" is run, + will try to find a C++ compiler and C++ header files, and if it succeeds, it + will try to build the C++ wrapper. + +. If you want to make use of the support for UTF-8 character strings in PCRE, + you must add --enable-utf8 to the "configure" command. Without it, the code + for handling UTF-8 is not included in the library. (Even when included, it + still has to be enabled by an option at run time.) + +. If, in addition to support for UTF-8 character strings, you want to include + support for the \P, \p, and \X sequences that recognize Unicode character + properties, you must add --enable-unicode-properties to the "configure" + command. This adds about 30K to the size of the library (in the form of a + property table); only the basic two-letter properties such as Lu are + supported. + +. You can build PCRE to recognize either CR or LF or the sequence CRLF as + indicating the end of a line. Whatever you specify at build time is the + default; the caller of PCRE can change the selection at run time. The default + newline indicator is a single LF character (the Unix standard). You can + specify the default newline indicator by adding --newline-is-cr or + --newline-is-lf or --newline-is-crlf to the "configure" command, + respectively. + +. When called via the POSIX interface, PCRE uses malloc() to get additional + storage for processing capturing parentheses if there are more than 10 of + them. You can increase this threshold by setting, for example, + + --with-posix-malloc-threshold=20 + + on the "configure" command. + +. PCRE has a counter that can be set to limit the amount of resources it uses. + If the limit is exceeded during a match, the match fails. The default is ten + million. You can change the default by setting, for example, + + --with-match-limit=500000 + + on the "configure" command. This is just the default; individual calls to + pcre_exec() can supply their own value. There is discussion on the pcreapi + man page. + +. There is a separate counter that limits the depth of recursive function calls + during a matching process. This also has a default of ten million, which is + essentially "unlimited". You can change the default by setting, for example, + + --with-match-limit-recursion=500000 + + Recursive function calls use up the runtime stack; running out of stack can + cause programs to crash in strange ways. There is a discussion about stack + sizes in the pcrestack man page. + +. The default maximum compiled pattern size is around 64K. You can increase + this by adding --with-link-size=3 to the "configure" command. You can + increase it even more by setting --with-link-size=4, but this is unlikely + ever to be necessary. If you build PCRE with an increased link size, test 2 + (and 5 if you are using UTF-8) will fail. Part of the output of these tests + is a representation of the compiled pattern, and this changes with the link + size. + +. You can build PCRE so that its internal match() function that is called from + pcre_exec() does not call itself recursively. Instead, it uses blocks of data + from the heap via special functions pcre_stack_malloc() and pcre_stack_free() + to save data that would otherwise be saved on the stack. To build PCRE like + this, use + + --disable-stack-for-recursion + + on the "configure" command. PCRE runs more slowly in this mode, but it may be + necessary in environments with limited stack sizes. This applies only to the + pcre_exec() function; it does not apply to pcre_dfa_exec(), which does not + use deeply nested recursion. + +The "configure" script builds eight files for the basic C library: + +. Makefile is the makefile that builds the library +. config.h contains build-time configuration options for the library +. pcre-config is a script that shows the settings of "configure" options +. libpcre.pc is data for the pkg-config command +. libtool is a script that builds shared and/or static libraries +. RunTest is a script for running tests on the library +. RunGrepTest is a script for running tests on the pcregrep command + +In addition, if a C++ compiler is found, the following are also built: + +. pcrecpp.h is the header file for programs that call PCRE via the C++ wrapper +. pcre_stringpiece.h is the header for the C++ "stringpiece" functions + +The "configure" script also creates config.status, which is an executable +script that can be run to recreate the configuration, and config.log, which +contains compiler output from tests that "configure" runs. + +Once "configure" has run, you can run "make". It builds two libraries, called +libpcre and libpcreposix, a test program called pcretest, and the pcregrep +command. If a C++ compiler was found on your system, it also builds the C++ +wrapper library, which is called libpcrecpp, and some test programs called +pcrecpp_unittest, pcre_scanner_unittest, and pcre_stringpiece_unittest. + +The command "make test" runs all the appropriate tests. Details of the PCRE +tests are given in a separate section of this document, below. + +You can use "make install" to copy the libraries, the public header files +pcre.h, pcreposix.h, pcrecpp.h, and pcre_stringpiece.h (the last two only if +the C++ wrapper was built), and the man pages to appropriate live directories +on your system, in the normal way. + +If you want to remove PCRE from your system, you can run "make uninstall". +This removes all the files that "make install" installed. However, it does not +remove any directories, because these are often shared with other programs. + + +Retrieving configuration information on Unix-like systems +--------------------------------------------------------- + +Running "make install" also installs the command pcre-config, which can be used +to recall information about the PCRE configuration and installation. For +example: + + pcre-config --version + +prints the version number, and + + pcre-config --libs + +outputs information about where the library is installed. This command can be +included in makefiles for programs that use PCRE, saving the programmer from +having to remember too many details. + +The pkg-config command is another system for saving and retrieving information +about installed libraries. Instead of separate commands for each library, a +single command is used. For example: + + pkg-config --cflags pcre + +The data is held in *.pc files that are installed in a directory called +pkgconfig. + + +Shared libraries on Unix-like systems +------------------------------------- + +The default distribution builds PCRE as shared libraries and static libraries, +as long as the operating system supports shared libraries. Shared library +support relies on the "libtool" script which is built as part of the +"configure" process. + +The libtool script is used to compile and link both shared and static +libraries. They are placed in a subdirectory called .libs when they are newly +built. The programs pcretest and pcregrep are built to use these uninstalled +libraries (by means of wrapper scripts in the case of shared libraries). When +you use "make install" to install shared libraries, pcregrep and pcretest are +automatically re-built to use the newly installed shared libraries before being +installed themselves. However, the versions left in the source directory still +use the uninstalled libraries. + +To build PCRE using static libraries only you must use --disable-shared when +configuring it. For example: + +./configure --prefix=/usr/gnu --disable-shared + +Then run "make" in the usual way. Similarly, you can use --disable-static to +build only shared libraries. + + +Cross-compiling on a Unix-like system +------------------------------------- + +You can specify CC and CFLAGS in the normal way to the "configure" command, in +order to cross-compile PCRE for some other host. However, during the building +process, the dftables.c source file is compiled *and run* on the local host, in +order to generate the default character tables (the chartables.c file). It +therefore needs to be compiled with the local compiler, not the cross compiler. +You can do this by specifying CC_FOR_BUILD (and if necessary CFLAGS_FOR_BUILD; +there are also CXX_FOR_BUILD and CXXFLAGS_FOR_BUILD for the C++ wrapper) +when calling the "configure" command. If they are not specified, they default +to the values of CC and CFLAGS. + + +Using HP's ANSI C++ compiler (aCC) +---------------------------------- + +Unless C++ support is disabled by specifiying the "--disable-cpp" option of the +"configure" script, you *must* include the "-AA" option in the CXXFLAGS +environment variable in order for the C++ components to compile correctly. + +Also, note that the aCC compiler on PA-RISC platforms may have a defect whereby +needed libraries fail to get included when specifying the "-AA" compiler +option. If you experience unresolved symbols when linking the C++ programs, +use the workaround of specifying the following environment variable prior to +running the "configure" script: + + CXXLDFLAGS="-lstd_v2 -lCsup_v2" + + +Building on non-Unix systems +---------------------------- + +For a non-Unix system, read the comments in the file NON-UNIX-USE, though if +the system supports the use of "configure" and "make" you may be able to build +PCRE in the same way as for Unix systems. + +PCRE has been compiled on Windows systems and on Macintoshes, but I don't know +the details because I don't use those systems. It should be straightforward to +build PCRE on any system that has a Standard C compiler, because it uses only +Standard C functions. + + +Testing PCRE +------------ + +To test PCRE on a Unix system, run the RunTest script that is created by the +configuring process. There is also a script called RunGrepTest that tests the +options of the pcregrep command. If the C++ wrapper library is build, three +test programs called pcrecpp_unittest, pcre_scanner_unittest, and +pcre_stringpiece_unittest are provided. + +Both the scripts and all the program tests are run if you obey "make runtest", +"make check", or "make test". For other systems, see the instructions in +NON-UNIX-USE. + +The RunTest script runs the pcretest test program (which is documented in its +own man page) on each of the testinput files (in the testdata directory) in +turn, and compares the output with the contents of the corresponding testoutput +file. A file called testtry is used to hold the main output from pcretest +(testsavedregex is also used as a working file). To run pcretest on just one of +the test files, give its number as an argument to RunTest, for example: + + RunTest 2 + +The first file can also be fed directly into the perltest script to check that +Perl gives the same results. The only difference you should see is in the first +few lines, where the Perl version is given instead of the PCRE version. + +The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(), +pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error +detection, and run-time flags that are specific to PCRE, as well as the POSIX +wrapper API. It also uses the debugging flag to check some of the internals of +pcre_compile(). + +If you build PCRE with a locale setting that is not the standard C locale, the +character tables may be different (see next paragraph). In some cases, this may +cause failures in the second set of tests. For example, in a locale where the +isprint() function yields TRUE for characters in the range 128-255, the use of +[:isascii:] inside a character class defines a different set of characters, and +this shows up in this test as a difference in the compiled code, which is being +listed for checking. Where the comparison test output contains [\x00-\x7f] the +test will contain [\x00-\xff], and similarly in some other cases. This is not a +bug in PCRE. + +The third set of tests checks pcre_maketables(), the facility for building a +set of character tables for a specific locale and using them instead of the +default tables. The tests make use of the "fr_FR" (French) locale. Before +running the test, the script checks for the presence of this locale by running +the "locale" command. If that command fails, or if it doesn't include "fr_FR" +in the list of available locales, the third test cannot be run, and a comment +is output to say why. If running this test produces instances of the error + + ** Failed to set locale "fr_FR" + +in the comparison output, it means that locale is not available on your system, +despite being listed by "locale". This does not mean that PCRE is broken. + +The fourth test checks the UTF-8 support. It is not run automatically unless +PCRE is built with UTF-8 support. To do this you must set --enable-utf8 when +running "configure". This file can be also fed directly to the perltest script, +provided you are running Perl 5.8 or higher. (For Perl 5.6, a small patch, +commented in the script, can be be used.) + +The fifth test checks error handling with UTF-8 encoding, and internal UTF-8 +features of PCRE that are not relevant to Perl. + +The sixth and test checks the support for Unicode character properties. It it +not run automatically unless PCRE is built with Unicode property support. To to +this you must set --enable-unicode-properties when running "configure". + +The seventh, eighth, and ninth tests check the pcre_dfa_exec() alternative +matching function, in non-UTF-8 mode, UTF-8 mode, and UTF-8 mode with Unicode +property support, respectively. The eighth and ninth tests are not run +automatically unless PCRE is build with the relevant support. + + +Character tables +---------------- + +PCRE uses four tables for manipulating and identifying characters whose values +are less than 256. The final argument of the pcre_compile() function is a +pointer to a block of memory containing the concatenated tables. A call to +pcre_maketables() can be used to generate a set of tables in the current +locale. If the final argument for pcre_compile() is passed as NULL, a set of +default tables that is built into the binary is used. + +The source file called chartables.c contains the default set of tables. This is +not supplied in the distribution, but is built by the program dftables +(compiled from dftables.c), which uses the ANSI C character handling functions +such as isalnum(), isalpha(), isupper(), islower(), etc. to build the table +sources. This means that the default C locale which is set for your system will +control the contents of these default tables. You can change the default tables +by editing chartables.c and then re-building PCRE. If you do this, you should +probably also edit Makefile to ensure that the file doesn't ever get +re-generated. + +The first two 256-byte tables provide lower casing and case flipping functions, +respectively. The next table consists of three 32-byte bit maps which identify +digits, "word" characters, and white space, respectively. These are used when +building 32-byte bit maps that represent character classes. + +The final 256-byte table has bits indicating various character types, as +follows: + + 1 white space character + 2 letter + 4 decimal digit + 8 hexadecimal digit + 16 alphanumeric or '_' + 128 regular expression metacharacter or binary zero + +You should not alter the set of characters that contain the 128 bit, as that +will cause PCRE to malfunction. + + +Manifest +-------- + +The distribution should contain the following files: + +(A) The actual source files of the PCRE library functions and their + headers: + + dftables.c auxiliary program for building chartables.c + + pcreposix.c ) + pcre_compile.c ) + pcre_config.c ) + pcre_dfa_exec.c ) + pcre_exec.c ) + pcre_fullinfo.c ) + pcre_get.c ) sources for the functions in the library, + pcre_globals.c ) and some internal functions that they use + pcre_info.c ) + pcre_maketables.c ) + pcre_ord2utf8.c ) + pcre_refcount.c ) + pcre_study.c ) + pcre_tables.c ) + pcre_try_flipped.c ) + pcre_ucp_searchfuncs.c) + pcre_valid_utf8.c ) + pcre_version.c ) + pcre_xclass.c ) + ucptable.c ) + + pcre_printint.src ) debugging function that is #included in pcretest, and + ) can also be #included in pcre_compile() + + pcre.h the public PCRE header file + pcreposix.h header for the external POSIX wrapper API + pcre_internal.h header for internal use + ucp.h ) headers concerned with + ucpinternal.h ) Unicode property handling + config.in template for config.h, which is built by configure + + pcrecpp.h the header file for the C++ wrapper + pcrecpparg.h.in "source" for another C++ header file + pcrecpp.cc ) + pcre_scanner.cc ) source for the C++ wrapper library + + pcre_stringpiece.h.in "source" for pcre_stringpiece.h, the header for the + C++ stringpiece functions + pcre_stringpiece.cc source for the C++ stringpiece functions + +(B) Auxiliary files: + + AUTHORS information about the author of PCRE + ChangeLog log of changes to the code + INSTALL generic installation instructions + LICENCE conditions for the use of PCRE + COPYING the same, using GNU's standard name + Makefile.in template for Unix Makefile, which is built by configure + NEWS important changes in this release + NON-UNIX-USE notes on building PCRE on non-Unix systems + README this file + RunTest.in template for a Unix shell script for running tests + RunGrepTest.in template for a Unix shell script for pcregrep tests + config.guess ) files used by libtool, + config.sub ) used only when building a shared library + config.h.in "source" for the config.h header file + configure a configuring shell script (built by autoconf) + configure.ac the autoconf input used to build configure + doc/Tech.Notes notes on the encoding + doc/*.3 man page sources for the PCRE functions + doc/*.1 man page sources for pcregrep and pcretest + doc/html/* HTML documentation + doc/pcre.txt plain text version of the man pages + doc/pcretest.txt plain text documentation of test program + doc/perltest.txt plain text documentation of Perl test program + install-sh a shell script for installing files + libpcre.pc.in "source" for libpcre.pc for pkg-config + ltmain.sh file used to build a libtool script + mkinstalldirs script for making install directories + pcretest.c comprehensive test program + pcredemo.c simple demonstration of coding calls to PCRE + perltest Perl test program + pcregrep.c source of a grep utility that uses PCRE + pcre-config.in source of script which retains PCRE information + pcrecpp_unittest.c ) + pcre_scanner_unittest.c ) test programs for the C++ wrapper + pcre_stringpiece_unittest.c ) + testdata/testinput* test data for main library tests + testdata/testoutput* expected test results + testdata/grep* input and output for pcregrep tests + +(C) Auxiliary files for Win32 DLL + + libpcre.def + libpcreposix.def + +(D) Auxiliary file for VPASCAL + + makevp.bat + +Philip Hazel +Email local part: ph10 +Email domain: cam.ac.uk +June 2006 Added: freeswitch/trunk/libs/pcre/RunGrepTest.in ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/RunGrepTest.in Tue Dec 19 14:54:26 2006 @@ -0,0 +1,208 @@ +#! /bin/sh + +# This file is generated by configure from RunGrepTest.in.

These were not Unix-like in form, and were quite +restricted in what they could do by comparison with Perl. The interesting part +about the algorithm was that the amount of space required to hold the compiled +form of an expression was known in advance. The code to apply an expression did +not operate by backtracking, as the original Henry Spencer code and current +Perl code does, but instead checked all possibilities simultaneously by keeping +a list of current states and checking all of them as it advanced through the +subject string. In the terminology of Jeffrey Friedl's book, it was a "DFA +algorithm". When the pattern was all used up, all remaining states were +possible matches, and the one matching the longest subset of the subject string +was chosen. This did not necessarily maximize the individual wild portions of +the pattern, as is expected in Unix and Perl-style regular expressions. + +Historical note 2 +----------------- + +By contrast, the code originally written by Henry Spencer (which was +subsequently heavily modified for Perl) compiles the expression twice: once in +a dummy mode in order to find out how much store will be needed, and then for +real. (The Perl version probably doesn't do this any more; I'm talking about +the original library.) The execution function operates by backtracking and +maximizing (or, optionally, minimizing in Perl) the amount of the subject that +matches individual wild portions of the pattern. This is an "NFA algorithm" in +Friedl's terminology. + +OK, here's the real stuff +------------------------- + +For the set of functions that form the "basic" PCRE library (which are +unrelated to those mentioned above), I tried at first to invent an algorithm +that used an amount of store bounded by a multiple of the number of characters +in the pattern, to save on compiling time. However, because of the greater +complexity in Perl regular expressions, I couldn't do this. In any case, a +first pass through the pattern is needed, for a number of reasons. PCRE works +by running a very degenerate first pass to calculate a maximum store size, and +then a second pass to do the real compile - which may use a bit less than the +predicted amount of store. The idea is that this is going to turn out faster +because the first pass is degenerate and the second pass can just store stuff +straight into the vector, which it knows is big enough. It does make the +compiling functions bigger, of course, but they have become quite big anyway to +handle all the Perl stuff. + +Traditional matching function +----------------------------- + +The "traditional", and original, matching function is called pcre_exec(), and +it implements an NFA algorithm, similar to the original Henry Spencer algorithm +and the way that Perl works. Not surprising, since it is intended to be as +compatible with Perl as possible. This is the function most users of PCRE will +use most of the time. + +Supplementary matching function +------------------------------- + +From PCRE 6.0, there is also a supplementary matching function called +pcre_dfa_exec(). This implements a DFA matching algorithm that searches +simultaneously for all possible matches that start at one point in the subject +string. (Going back to my roots: see Historical Note 1 above.) This function +intreprets the same compiled pattern data as pcre_exec(); however, not all the +facilities are available, and those that are do not always work in quite the +same way. See the user documentation for details. + +Format of compiled patterns +--------------------------- + +The compiled form of a pattern is a vector of bytes, containing items of +variable length. The first byte in an item is an opcode, and the length of the +item is either implicit in the opcode or contained in the data bytes that +follow it. + +In many cases below "two-byte" data values are specified. This is in fact just +a default. PCRE can be compiled to use 3-byte or 4-byte values (impairing the +performance). This is necessary only when patterns whose compiled length is +greater than 64K are going to be processed. In this description, we assume the +"normal" compilation options. + +A list of all the opcodes follows: + +Opcodes with no following data +------------------------------ + +These items are all just one byte long + + OP_END end of pattern + OP_ANY match any character + OP_ANYBYTE match any single byte, even in UTF-8 mode + OP_SOD match start of data: \A + OP_SOM, start of match (subject + offset): \G + OP_CIRC ^ (start of data, or after \n in multiline) + OP_NOT_WORD_BOUNDARY \W + OP_WORD_BOUNDARY \w + OP_NOT_DIGIT \D + OP_DIGIT \d + OP_NOT_WHITESPACE \S + OP_WHITESPACE \s + OP_NOT_WORDCHAR \W + OP_WORDCHAR \w + OP_EODN match end of data or \n at end: \Z + OP_EOD match end of data: \z + OP_DOLL $ (end of data, or before \n in multiline) + OP_EXTUNI match an extended Unicode character + + +Repeating single characters +--------------------------- + +The common repeats (*, +, ?) when applied to a single character use the +following opcodes: + + OP_STAR + OP_MINSTAR + OP_PLUS + OP_MINPLUS + OP_QUERY + OP_MINQUERY + +In ASCII mode, these are two-byte items; in UTF-8 mode, the length is variable. +Those with "MIN" in their name are the minimizing versions. Each is followed by +the character that is to be repeated. Other repeats make use of + + OP_UPTO + OP_MINUPTO + OP_EXACT + +which are followed by a two-byte count (most significant first) and the +repeated character. OP_UPTO matches from 0 to the given number. A repeat with a +non-zero minimum and a fixed maximum is coded as an OP_EXACT followed by an +OP_UPTO (or OP_MINUPTO). + + +Repeating character types +------------------------- + +Repeats of things like \d are done exactly as for single characters, except +that instead of a character, the opcode for the type is stored in the data +byte. The opcodes are: + + OP_TYPESTAR + OP_TYPEMINSTAR + OP_TYPEPLUS + OP_TYPEMINPLUS + OP_TYPEQUERY + OP_TYPEMINQUERY + OP_TYPEUPTO + OP_TYPEMINUPTO + OP_TYPEEXACT + + +Match by Unicode property +------------------------- + +OP_PROP and OP_NOTPROP are used for positive and negative matches of a +character by testing its Unicode property (the \p and \P escape sequences). +Each is followed by two bytes that encode the desired property as a type and a +value. + +Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by +three bytes: OP_PROP or OP_NOTPROP and then the desired property type and +value. + + +Matching literal characters +--------------------------- + +The OP_CHAR opcode is followed by a single character that is to be matched +casefully. For caseless matching, OP_CHARNC is used. In UTF-8 mode, the +character may be more than one byte long. (Earlier versions of PCRE used +multi-character strings, but this was changed to allow some new features to be +added.) + + +Character classes +----------------- + +If there is only one character, OP_CHAR or OP_CHARNC is used for a positive +class, and OP_NOT for a negative one (that is, for something like [^a]). +However, in UTF-8 mode, the use of OP_NOT applies only to characters with +values < 128, because OP_NOT is confined to single bytes. + +Another set of repeating opcodes (OP_NOTSTAR etc.) are used for a repeated, +negated, single-character class. The normal ones (OP_STAR etc.) are used for a +repeated positive single-character class. + +When there's more than one character in a class and all the characters are less +than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a negative +one. In either case, the opcode is followed by a 32-byte bit map containing a 1 +bit for every character that is acceptable. The bits are counted from the least +significant end of each byte. + +The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8 mode, +subject characters with values greater than 256 can be handled correctly. For +OP_CLASS they don't match, whereas for OP_NCLASS they do. + +For classes containing characters with values > 255, OP_XCLASS is used. It +optionally uses a bit map (if any characters lie within it), followed by a list +of pairs and single characters. There is a flag character than indicates +whether it's a positive or a negative class. + + +Back references +--------------- + +OP_REF is followed by two bytes containing the reference number. + + +Repeating character classes and back references +----------------------------------------------- + +Single-character classes are handled specially (see above). This applies to +OP_CLASS and OP_REF. In both cases, the repeat information follows the base +item. The matching code looks at the following opcode to see if it is one of + + OP_CRSTAR + OP_CRMINSTAR + OP_CRPLUS + OP_CRMINPLUS + OP_CRQUERY + OP_CRMINQUERY + OP_CRRANGE + OP_CRMINRANGE + +All but the last two are just single-byte items. The others are followed by +four bytes of data, comprising the minimum and maximum repeat counts. + + +Brackets and alternation +------------------------ + +A pair of non-capturing (round) brackets is wrapped round each expression at +compile time, so alternation always happens in the context of brackets. + +Non-capturing brackets use the opcode OP_BRA, while capturing brackets use +OP_BRA+1, OP_BRA+2, etc. [Note for North Americans: "bracket" to some English +speakers, including myself, can be round, square, curly, or pointy. Hence this +usage.] + +Originally PCRE was limited to 99 capturing brackets (so as not to use up all +the opcodes). From release 3.5, there is no limit. What happens is that the +first ones, up to EXTRACT_BASIC_MAX are handled with separate opcodes, as +above. If there are more, the opcode is set to EXTRACT_BASIC_MAX+1, and the +first operation in the bracket is OP_BRANUMBER, followed by a 2-byte bracket +number. This opcode is ignored while matching, but is fished out when handling +the bracket itself. (They could have all been done like this, but I was making +minimal changes.) + +A bracket opcode is followed by LINK_SIZE bytes which give the offset to the +next alternative OP_ALT or, if there aren't any branches, to the matching +OP_KET opcode. Each OP_ALT is followed by LINK_SIZE bytes giving the offset to +the next one, or to the OP_KET opcode. + +OP_KET is used for subpatterns that do not repeat indefinitely, while +OP_KETRMIN and OP_KETRMAX are used for indefinite repetitions, minimally or +maximally respectively. All three are followed by LINK_SIZE bytes giving (as a +positive number) the offset back to the matching OP_BRA opcode. + +If a subpattern is quantified such that it is permitted to match zero times, it +is preceded by one of OP_BRAZERO or OP_BRAMINZERO. These are single-byte +opcodes which tell the matcher that skipping this subpattern entirely is a +valid branch. + +A subpattern with an indefinite maximum repetition is replicated in the +compiled data its minimum number of times (or once with OP_BRAZERO if the +minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX +as appropriate. + +A subpattern with a bounded maximum repetition is replicated in a nested +fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO +before each replication after the minimum, so that, for example, (abc){2,5} is +compiled as (abc)(abc)((abc)((abc)(abc)?)?)?. + + +Assertions +---------- + +Forward assertions are just like other subpatterns, but starting with one of +the opcodes OP_ASSERT or OP_ASSERT_NOT. Backward assertions use the opcodes +OP_ASSERTBACK and OP_ASSERTBACK_NOT, and the first opcode inside the assertion +is OP_REVERSE, followed by a two byte count of the number of characters to move +back the pointer in the subject string. When operating in UTF-8 mode, the count +is a character count rather than a byte count. A separate count is present in +each alternative of a lookbehind assertion, allowing them to have different +fixed lengths. + + +Once-only subpatterns +--------------------- + +These are also just like other subpatterns, but they start with the opcode +OP_ONCE. + + +Conditional subpatterns +----------------------- + +These are like other subpatterns, but they start with the opcode OP_COND. If +the condition is a back reference, this is stored at the start of the +subpattern using the opcode OP_CREF followed by two bytes containing the +reference number. If the condition is "in recursion" (coded as "(?(R)"), the +same scheme is used, with a "reference number" of 0xffff. Otherwise, a +conditional subpattern always starts with one of the assertions. + + +Recursion +--------- + +Recursion either matches the current regex, or some subexpression. The opcode +OP_RECURSE is followed by an value which is the offset to the starting bracket +from the start of the whole pattern. From release 6.5, OP_RECURSE is +automatically wrapped inside OP_ONCE brackets (because otherwise some patterns +broke it). OP_RECURSE is also used for "subroutine" calls, even though they +are not strictly a recursion. + + +Callout +------- + +OP_CALLOUT is followed by one byte of data that holds a callout number in the +range 0 to 254 for manual callouts, or 255 for an automatic callout. In both +cases there follows a two-byte value giving the offset in the pattern to the +start of the following item, and another two-byte item giving the length of the +next item. + + +Changing options +---------------- + +If any of the /i, /m, or /s options are changed within a pattern, an OP_OPT +opcode is compiled, followed by one byte containing the new settings of these +flags. If there are several alternatives, there is an occurrence of OP_OPT at +the start of all those following the first options change, to set appropriate +options for the start of the alternative. Immediately after the end of the +group there is another such item to reset the flags to their previous values. A +change of flag right at the very start of the pattern can be handled entirely +at compile time, and so does not cause anything to be put into the compiled +data. + +Philip Hazel +June 2006 Added: freeswitch/trunk/libs/pcre/doc/html/index.html ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/doc/html/index.html Tue Dec 19 14:54:26 2006 @@ -0,0 +1,128 @@ +<html> +<head> +<title>PCRE specification</title> +</head> +<body bgcolor="#FFFFFF" text="#00005A" link="#0066FF" alink="#3399FF" vlink="#2222BB"> +<h1>Perl-compatible Regular Expressions (PCRE)</h1> +<p> +The HTML documentation for PCRE comprises the following pages: +</p> + +<table> +<tr><td><a href="pcre.html">pcre</a></td> + <td>  Introductory page</td></tr> + +<tr><td><a href="pcreapi.html">pcreapi</a></td> + <td>  PCRE's native API</td></tr> + +<tr><td><a href="pcrebuild.html">pcrebuild</a></td> + <td>  Options for building PCRE</td></tr> + +<tr><td><a href="pcrecallout.html">pcrecallout</a></td> + <td>  The <i>callout</i> facility</td></tr> + +<tr><td><a href="pcrecompat.html">pcrecompat</a></td> + <td>  Compability with Perl</td></tr> + +<tr><td><a href="pcrecpp.html">pcrecpp</a></td> + <td>  The C++ wrapper for the PCRE library</td></tr> + +<tr><td><a href="pcregrep.html">pcregrep</a></td> + <td>  The <b>pcregrep</b> command</td></tr> + +<tr><td><a href="pcrematching.html">pcrematching</a></td> + <td>  Discussion of the two matching algorithms</td></tr> + +<tr><td><a href="pcrepartial.html">pcrepartial</a></td> + <td>  Using PCRE for partial matching</td></tr> + +<tr><td><a href="pcrepattern.html">pcrepattern</a></td> + <td>  Specification of the regular expressions supported by PCRE</td></tr> + +<tr><td><a href="pcreperform.html">pcreperform</a></td> + <td>  Some comments on performance</td></tr> + +<tr><td><a href="pcreposix.html">pcreposix</a></td> + <td>  The POSIX API to the PCRE library</td></tr> + +<tr><td><a href="pcreprecompile.html">pcreprecompile</a></td> + <td>  How to save and re-use compiled patterns</td></tr> + +<tr><td><a href="pcresample.html">pcresample</a></td> + <td>  Description of the sample program</td></tr> + +<tr><td><a href="pcrestack.html">pcrestack</a></td> + <td>  Discussion of PCRE's stack usage</td></tr> + +<tr><td><a href="pcretest.html">pcretest</a></td> + <td>  The <b>pcretest</b> command for testing PCRE</td></tr> +</table> + +<p> +There are also individual pages that summarize the interface for each function +in the library: +</p> + +<table> + +<tr><td><a href="pcre_compile.html">pcre_compile</a></td> + <td>  Compile a regular expression</td></tr> + +<tr><td><a href="pcre_compile2.html">pcre_compile2</a></td> + <td>  Compile a regular expression (alternate interface)</td></tr> + +<tr><td><a href="pcre_config.html">pcre_config</a></td> + <td>  Show build-time configuration options</td></tr> + +<tr><td><a href="pcre_copy_named_substring.html">pcre_copy_named_substring</a></td> + <td>  Extract named substring into given buffer</td></tr> + +<tr><td><a href="pcre_copy_substring.html">pcre_copy_substring</a></td> + <td>  Extract numbered substring into given buffer</td></tr> + +<tr><td><a href="pcre_dfa_exec.html">pcre_dfa_exec</a></td> + <td>  Match a compiled pattern to a subject string + (DFA algorithm;

However, this support has to be explicitly +enabled; it is not the default. +</P> +<P> +In addition to the Perl-compatible matching function, PCRE also contains an +alternative matching function that matches the same compiled patterns in a +different way. In certain circumstances, the alternative function has some +advantages. For a discussion of the two matching algorithms, see the +<a href="pcrematching.html"><b>pcrematching</b></a> +page. +</P> +<P> +PCRE is written in C and released as a C library. A number of people have +written wrappers and interfaces of various kinds. In particular, Google Inc. +have provided a comprehensive C++ wrapper. This is now included as part of the +PCRE distribution. The +<a href="pcrecpp.html"><b>pcrecpp</b></a> +page has details of this interface. Other people's contributions can be found +in the <i>Contrib</i> directory at the primary FTP site, which is: +<a href="ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre">ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre</a> +</P> +<P> +Details of exactly which Perl regular expression features are and are not +supported by PCRE are given in separate documents.

The +<a href="pcre_config.html"><b>pcre_config()</b></a> +function makes it possible for a client to discover which features are +available. The features themselves are described in the +<a href="pcrebuild.html"><b>pcrebuild</b></a> +page. Documentation about building PCRE for various operating systems can be +found in the <b>README</b> file in the source distribution. +</P> +<P> +The library contains a number of undocumented internal functions and data +tables that are used by more than one of the exported external functions, but +which are not intended for use by external callers. Their names all begin with +"_pcre_", which hopefully will not provoke any name clashes. In some +environments, it is possible to control which external symbols are exported +when a shared library is built, and in these cases the undocumented symbols are +not exported. +</P> +<br><a name="SEC2" href="#TOC1">USER DOCUMENTATION</a><br> +<P> +The user documentation for PCRE comprises a number of different sections. In +the "man" format, each of these is a separate "man page". In the HTML format, +each is a separate page, linked from the index page. In the plain text format, +all the sections are concatenated, for ease of searching.

If you want to process +regular expressions that are truly enormous, you can compile PCRE with an +internal linkage size of 3 or 4 (see the <b>README</b> file in the source +distribution and the +<a href="pcrebuild.html"><b>pcrebuild</b></a> +documentation for details). In these cases the limit is substantially larger. +However, the speed of execution will be slower. +</P> +<P> +All values in repeating quantifiers must be less than 65536. The maximum +compiled length of subpattern with an explicit repeat count is 30000 bytes. The +maximum number of capturing subpatterns is 65535. +</P> +<P> +There is no limit to the number of non-capturing subpatterns, but the maximum +depth of nesting of all kinds of parenthesized subpattern, including capturing +subpatterns, assertions, and other types of subpattern, is 200. +</P> +<P> +The maximum length of name for a named subpattern is 32, and the maximum number +of named subpatterns is 10000. +</P> +<P> +The maximum length of a subject string is the largest positive number that an +integer variable can hold. However, when using the traditional matching +function, PCRE uses recursion to handle subpatterns and indefinite repetition. +This means that the available stack space may limit the size of a subject +string that can be processed by certain patterns. For a discussion of stack +issues, see the +<a href="pcrestack.html"><b>pcrestack</b></a> +documentation. +<a name="utf8support"></a></P> +<br><a name="SEC4" href="#TOC1">UTF-8 AND UNICODE PROPERTY SUPPORT</a><br> +<P> +From release 3.3, PCRE has had some support for character strings encoded in +the UTF-8 format. For release 4.0 this was greatly extended to cover most +common requirements, and in release 5.0 additional support for Unicode general +category properties was added. +</P> +<P> +In order process UTF-8 strings, you must build PCRE to include UTF-8 support in +the code, and, in addition, you must call +<a href="pcre_compile.html"><b>pcre_compile()</b></a> +with the PCRE_UTF8 option flag. When you do this, both the pattern and any +subject strings that are matched against it are treated as UTF-8 strings +instead of just strings of bytes. +</P> +<P> +If you compile PCRE with UTF-8 support, but do not use it at run time, the +library will be a bit bigger, but the additional run time overhead is limited +to testing the PCRE_UTF8 flag in several places, so should not be very large. +</P> +<P> +If PCRE is built with Unicode character property support (which implies UTF-8 +support), the escape sequences \p{..}, \P{..}, and \X are supported. +The available properties that can be tested are limited to the general +category properties such as Lu for an upper case letter or Nd for a decimal +number, the Unicode script names such as Arabic or Han, and the derived +properties Any and L&. A full list is given in the +<a href="pcrepattern.html"><b>pcrepattern</b></a> +documentation. Only the short names for properties are supported. For example, +\p{L} matches a letter. Its Perl synonym, \p{Letter}, is not supported. +Furthermore, in Perl, many properties may optionally be prefixed by "Is", for +compatibility with Perl 5.6. PCRE does not support this. +</P> +<P> +The following comments apply when PCRE is running in UTF-8 mode: +</P> +<P> +1. When you set the PCRE_UTF8 flag, the strings passed as patterns and subjects +are checked for validity on entry to the relevant functions. If an invalid +UTF-8 string is passed, an error return is given. In some situations, you may +already know that your strings are valid, and therefore want to skip these +checks in order to improve performance. If you set the PCRE_NO_UTF8_CHECK flag +at compile time or at run time, PCRE assumes that the pattern or subject it +is given (respectively) contains only valid UTF-8 codes. In this case, it does +not diagnose an invalid UTF-8 string. If you pass an invalid UTF-8 string to +PCRE when PCRE_NO_UTF8_CHECK is set, the results are undefined. Your program +may crash. +</P> +<P> +2. An unbraced hexadecimal escape sequence (such as \xb3) matches a two-byte +UTF-8 character if the value is greater than 127. +</P> +<P> +3. Octal numbers up to \777 are recognized, and match two-byte UTF-8 +characters for values greater than \177. +</P> +<P> +4. Repeat quantifiers apply to complete UTF-8 characters, not to individual +bytes, for example: \x{100}{3}. +</P> +<P> +5. The dot metacharacter matches one UTF-8 character instead of a single byte. +</P> +<P> +6. The escape sequence \C can be used to match a single byte in UTF-8 mode, +but its use can lead to some strange effects. This facility is not available in +the alternative matching function, <b>pcre_dfa_exec()</b>. +</P> +<P> +7. The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly +test characters of any code value, but the characters that PCRE recognizes as +digits, spaces, or word characters remain the same set as before, all with +values less than 256. This remains true even when PCRE includes Unicode +property support, because to do otherwise would slow down PCRE in many common +cases. If you really want to test for a wider sense of, say, "digit", you +must use Unicode property tests such as \p{Nd}. +</P> +<P> +8. Similarly, characters that match the POSIX named character classes are all +low-valued characters. +</P> +<P> +9. Case-insensitive matching applies only to characters whose values are less +than 128, unless PCRE is built with Unicode property support. Even when Unicode +property support is available, PCRE still uses its own character tables when +checking the case of low-valued characters, so as not to degrade performance. +The Unicode property information is used only for characters with higher +values. Even when Unicode property support is available, PCRE supports +case-insensitive matching only when there is a one-to-one mapping between a +letter's cases. There are a small number of many-to-one mappings in Unicode; +these are not supported by PCRE. +</P> +<br><a name="SEC5" href="#TOC1">AUTHOR</a><br> +<P> +Philip Hazel +<br> +University Computing Service, +<br> +Cambridge CB2 3QG, England. +</P> +<P> +Putting an actual email address here seems to have been a spam magnet, so I've +taken it away.

There is +also a set of wrapper functions that correspond to the POSIX regular expression +API. These are described in the +<a href="pcreposix.html"><b>pcreposix</b></a> +documentation. Both of these APIs define a set of C function calls. A C++ +wrapper is distributed with PCRE. It is documented in the +<a href="pcrecpp.html"><b>pcrecpp</b></a> +page. +</P> +<P> +The native API C function prototypes are defined in the header file +<b>pcre.h</b>, and on Unix systems the library itself is called <b>libpcre</b>. +It can normally be accessed by adding <b>-lpcre</b> to the command for linking +an application that uses PCRE. The header file defines the macros PCRE_MAJOR +and PCRE_MINOR to contain the major and minor release numbers for the library. +Applications can use these to include support for different releases of PCRE. +</P> +<P> +The functions <b>pcre_compile()</b>, <b>pcre_compile2()</b>, <b>pcre_study()</b>, +and <b>pcre_exec()</b> are used for compiling and matching regular expressions +in a Perl-compatible manner. A sample program that demonstrates the simplest +way of using them is provided in the file called <i>pcredemo.c</i> in the source +distribution. The +<a href="pcresample.html"><b>pcresample</b></a> +documentation describes how to run it. +</P> +<P> +A second matching function, <b>pcre_dfa_exec()</b>, which is not +Perl-compatible, is also provided. This uses a different algorithm for the +matching. The alternative algorithm finds all possible matches (at a given +point in the subject). However, this algorithm does not return captured +substrings. A description of the two matching algorithms and their advantages +and disadvantages is given in the +<a href="pcrematching.html"><b>pcrematching</b></a> +documentation. +</P> +<P> +In addition to the main compiling and matching functions, there are convenience +functions for extracting captured substrings from a subject string that is +matched by <b>pcre_exec()</b>. They are: +<pre> + <b>pcre_copy_substring()</b> + <b>pcre_copy_named_substring()</b> + <b>pcre_get_substring()</b> + <b>pcre_get_named_substring()</b> + <b>pcre_get_substring_list()</b> + <b>pcre_get_stringnumber()</b> + <b>pcre_get_stringtable_entries()</b> +</pre> +<b>pcre_free_substring()</b> and <b>pcre_free_substring_list()</b> are also +provided, to free the memory used for extracted strings. +</P> +<P> +The function <b>pcre_maketables()</b> is used to build a set of character tables +in the current locale for passing to <b>pcre_compile()</b>, <b>pcre_exec()</b>, +or <b>pcre_dfa_exec()</b>. This is an optional facility that is provided for +specialist use. Most commonly, no special tables are passed, in which case +internal tables that are generated when PCRE is built are used. +</P> +<P> +The function <b>pcre_fullinfo()</b> is used to find out information about a +compiled pattern; <b>pcre_info()</b> is an obsolete version that returns only +some of the available information, but is retained for backwards compatibility. +The function <b>pcre_version()</b> returns a pointer to a string containing the +version of PCRE and its date of release. +</P> +<P> +The function <b>pcre_refcount()</b> maintains a reference count in a data block +containing a compiled pattern. This is provided for the benefit of +object-oriented applications. +</P> +<P> +The global variables <b>pcre_malloc</b> and <b>pcre_free</b> initially contain +the entry points of the standard <b>malloc()</b> and <b>free()</b> functions, +respectively. PCRE calls the memory management functions via these variables, +so a calling program can replace them if it wishes to intercept the calls. This +should be done before calling any PCRE functions. +</P> +<P> +The global variables <b>pcre_stack_malloc</b> and <b>pcre_stack_free</b> are also +indirections to memory management functions. These special functions are used +only when PCRE is compiled to use the heap for remembering data, instead of +recursive function calls, when running the <b>pcre_exec()</b> function. See the +<a href="pcrebuild.html"><b>pcrebuild</b></a> +documentation for details of how to do this. It is a non-standard way of +building PCRE, for use in environments that have limited stacks. Because of the +greater use of memory management, it runs more slowly. Separate functions are +provided so that special-purpose external code can be used for this case. When +used, these functions are always called in a stack-like manner (last obtained, +first freed), and always for memory blocks of the same size. There is a +discussion about PCRE's stack usage in the +<a href="pcrestack.html"><b>pcrestack</b></a> +documentation. +</P> +<P> +The global variable <b>pcre_callout</b> initially contains NULL. It can be set +by the caller to a "callout" function, which PCRE will then call at specified +points during a matching operation. Details are given in the +<a href="pcrecallout.html"><b>pcrecallout</b></a> +documentation. +</P> +<br><a name="SEC3" href="#TOC1">NEWLINES</a><br> +<P> +PCRE supports three different conventions for indicating line breaks in +strings: a single CR character, a single LF character, or the two-character +sequence CRLF. All three are used as "standard" by different operating systems. +When PCRE is built, a default can be specified. The default default is LF, +which is the Unix standard. When PCRE is run, the default can be overridden, +either when a pattern is compiled, or when it is matched. +<br> +<br> +In the PCRE documentation the word "newline" is used to mean "the character or +pair of characters that indicate a line break". +</P> +<br><a name="SEC4" href="#TOC1">MULTITHREADING</a><br> +<P> +The PCRE functions can be used in multi-threading applications, with the +proviso that the memory management functions pointed to by <b>pcre_malloc</b>, +<b>pcre_free</b>, <b>pcre_stack_malloc</b>, and <b>pcre_stack_free</b>, and the +callout function pointed to by <b>pcre_callout</b>, are shared by all threads. +</P> +<P> +The compiled form of a regular expression is not altered during matching, so +the same compiled pattern can safely be used by several threads at once. +</P> +<br><a name="SEC5" href="#TOC1">SAVING PRECOMPILED PATTERNS FOR LATER USE</a><br> +<P> +The compiled form of a regular expression can be saved and re-used at a later +time, possibly by a different program, and even on a host other than the one on +which it was compiled.

The three values that are supported +are: 10 for LF, 13 for CR, and 3338 for CRLF. The default should normally be +the standard sequence for your operating system. +<pre> + PCRE_CONFIG_LINK_SIZE +</pre> +The output is an integer that contains the number of bytes used for internal +linkage in compiled regular expressions. The value is 2, 3, or 4. Larger values +allow larger regular expressions to be compiled, at the expense of slower +matching. The default value of 2 is sufficient for all but the most massive +patterns, since it allows the compiled pattern to be up to 64K in size. +<pre> + PCRE_CONFIG_POSIX_MALLOC_THRESHOLD +</pre> +The output is an integer that contains the threshold above which the POSIX +interface uses <b>malloc()</b> for output vectors. Further details are given in +the +<a href="pcreposix.html"><b>pcreposix</b></a> +documentation. +<pre> + PCRE_CONFIG_MATCH_LIMIT +</pre> +The output is an integer that gives the default limit for the number of +internal matching function calls in a <b>pcre_exec()</b> execution. Further +details are given with <b>pcre_exec()</b> below. +<pre> + PCRE_CONFIG_MATCH_LIMIT_RECURSION +</pre> +The output is an integer that gives the default limit for the depth of +recursion when calling the internal matching function in a <b>pcre_exec()</b> +execution. Further details are given with <b>pcre_exec()</b> below. +<pre> + PCRE_CONFIG_STACKRECURSE +</pre> +The output is an integer that is set to one if internal recursion when running +<b>pcre_exec()</b> is implemented by recursive function calls that use the stack +to remember their state. This is the usual way that PCRE is compiled. The +output is zero if PCRE was compiled to use blocks of data on the heap instead +of recursive function calls.

For these options, the contents of the <i>options</i> argument +specifies their initial settings at the start of compilation and execution.

This is in addition to the +textual error message. Error codes and messages are listed below. +</P> +<P> +If the final argument, <i>tableptr</i>, is NULL, PCRE uses a default set of +character tables that are built when PCRE is compiled, using the default C +locale. Otherwise, <i>tableptr</i> must be an address that is the result of a +call to <b>pcre_maketables()</b>. This value is stored with the compiled +pattern, and used again by <b>pcre_exec()</b>, unless another table pointer is +passed to it. For more discussion, see the section on locale support below. +</P> +<P> +This code fragment shows a typical straightforward call to <b>pcre_compile()</b>: +<pre> + pcre *re; + const char *error; + int erroffset; + re = pcre_compile( + "^A.*Z", /* the pattern */ + 0, /* default options */ + &error, /* for error message */ + &erroffset, /* for error offset */ + NULL); /* use default character tables */ +</pre> +The following names for option bits are defined in the <b>pcre.h</b> header +file: +<pre> + PCRE_ANCHORED +</pre> +If this bit is set, the pattern is forced to be "anchored", that is, it is +constrained to match only at the first matching point in the string that is +being searched (the "subject string"). This effect can also be achieved by +appropriate constructs in the pattern itself, which is the only way to do it in +Perl. +<pre> + PCRE_AUTO_CALLOUT +</pre> +If this bit is set, <b>pcre_compile()</b> automatically inserts callout items, +all with number 255, before each pattern item. For discussion of the callout +facility, see the +<a href="pcrecallout.html"><b>pcrecallout</b></a> +documentation. +<pre> + PCRE_CASELESS +</pre> +If this bit is set, letters in the pattern match both upper and lower case +letters. It is equivalent to Perl's /i option, and it can be changed within a +pattern by a (?i) option setting. In UTF-8 mode, PCRE always understands the +concept of case for characters whose values are less than 128, so caseless +matching is always possible. For characters with higher values, the concept of +case is supported if PCRE is compiled with Unicode property support, but not +otherwise. If you want to use caseless matching for characters 128 and above, +you must ensure that PCRE is compiled with Unicode property support as well as +with UTF-8 support. +<pre> + PCRE_DOLLAR_ENDONLY +</pre> +If this bit is set, a dollar metacharacter in the pattern matches only at the +end of the subject string. Without this option, a dollar also matches +immediately before a newline at the end of the string (but not before any other +newlines). The PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is set. +There is no equivalent to this option in Perl, and no way to set it within a +pattern. +<pre> + PCRE_DOTALL +</pre> +If this bit is set, a dot metacharater in the pattern matches all characters, +including those that indicate newline. Without it, a dot does not match when +the current position is at a newline. This option is equivalent to Perl's /s +option, and it can be changed within a pattern by a (?s) option setting. A +negative class such as [^a] always matches newlines, independent of the setting +of this option. +<pre> + PCRE_DUPNAMES +</pre> +If this bit is set, names used to identify capturing subpatterns need not be +unique. This can be helpful for certain types of pattern when it is known that +only one instance of the named subpattern can ever be matched. There are more +details of named subpatterns below; see also the +<a href="pcrepattern.html"><b>pcrepattern</b></a> +documentation. +<pre> + PCRE_EXTENDED +</pre> +If this bit is set, whitespace data characters in the pattern are totally +ignored except when escaped or inside a character class. Whitespace does not +include the VT character (code 11). In addition, characters between an +unescaped # outside a character class and the next newline, inclusive, are also +ignored. This is equivalent to Perl's /x option, and it can be changed within a +pattern by a (?x) option setting. +</P> +<P> +This option makes it possible to include comments inside complicated patterns. +Note, however, that this applies only to data characters. Whitespace characters +may never appear within special character sequences in a pattern, for example +within the sequence (?( which introduces a conditional subpattern. +<pre> + PCRE_EXTRA +</pre> +This option was invented in order to turn on additional functionality of PCRE +that is incompatible with Perl, but it is currently of very little use. When +set, any backslash in a pattern that is followed by a letter that has no +special meaning causes an error, thus reserving these combinations for future +expansion. By default, as in Perl, a backslash followed by a letter with no +special meaning is treated as a literal. (Perl can, however, be persuaded to +give a warning for this.) There are at present no other features controlled by +this option. It can also be set by a (?X) option setting within a pattern. +<pre> + PCRE_FIRSTLINE +</pre> +If this option is set, an unanchored pattern is required to match before or at +the first newline in the subject string, though the matched text may continue +over the newline. +<pre> + PCRE_MULTILINE +</pre> +By default, PCRE treats the subject string as consisting of a single line of +characters (even if it actually contains newlines). The "start of line" +metacharacter (^) matches only at the start of the string, while the "end of +line" metacharacter ($) matches only at the end of the string, or before a +terminating newline (unless PCRE_DOLLAR_ENDONLY is set). This is the same as +Perl. +</P> +<P> +When PCRE_MULTILINE it is set, the "start of line" and "end of line" constructs +match immediately following or immediately before internal newlines in the +subject string, respectively, as well as at the very start and end. This is +equivalent to Perl's /m option, and it can be changed within a pattern by a +(?m) option setting. If there are no newlines in a subject string, or no +occurrences of ^ or $ in a pattern, setting PCRE_MULTILINE has no effect. +<pre> + PCRE_NEWLINE_CR + PCRE_NEWLINE_LF + PCRE_NEWLINE_CRLF +</pre> +These options override the default newline definition that was chosen when PCRE +was built. Setting the first or the second specifies that a newline is +indicated by a single character (CR or LF, respectively). Setting both of them +specifies that a newline is indicated by the two-character CRLF sequence. For +convenience, PCRE_NEWLINE_CRLF is defined to contain both bits. The only time +that a line break is relevant when compiling a pattern is if PCRE_EXTENDED is +set, and an unescaped # outside a character class is encountered. This +indicates a comment that lasts until after the next newline. +</P> +<P> +The newline option set at compile time becomes the default that is used for +<b>pcre_exec()</b> and <b>pcre_dfa_exec()</b>, but it can be overridden. +<pre> + PCRE_NO_AUTO_CAPTURE +</pre> +If this option is set, it disables the use of numbered capturing parentheses in +the pattern. Any opening parenthesis that is not followed by ? behaves as if it +were followed by ?: but named parentheses can still be used for capturing (and +they acquire numbers in the usual way). There is no equivalent of this option +in Perl. +<pre> + PCRE_UNGREEDY +</pre> +This option inverts the "greediness" of the quantifiers so that they are not +greedy by default, but become greedy if followed by "?". It is not compatible +with Perl. It can also be set by a (?U) option setting within the pattern. +<pre> + PCRE_UTF8 +</pre> +This option causes PCRE to regard both the pattern and the subject as strings +of UTF-8 characters instead of single-byte character strings. However, it is +available only when PCRE is built to include UTF-8 support. If not, the use +of this option provokes an error. Details of how this option changes the +behaviour of PCRE are given in the +<a href="pcre.html#utf8support">section on UTF-8 support</a> +in the main +<a href="pcre.html"><b>pcre</b></a> +page. +<pre> + PCRE_NO_UTF8_CHECK +</pre> +When PCRE_UTF8 is set, the validity of the pattern as a UTF-8 string is +automatically checked.

For patterns that are +not anchored, the count restarts from zero for each position in the subject +string. +</P> +<P> +The default value for the limit can be set when PCRE is built; the default +default is 10 million, which handles all but the most extreme cases. You can +override the default by suppling <b>pcre_exec()</b> with a <b>pcre_extra</b> +block in which <i>match_limit</i> is set, and PCRE_EXTRA_MATCH_LIMIT is set in +the <i>flags</i> field. If the limit is exceeded, <b>pcre_exec()</b> returns +PCRE_ERROR_MATCHLIMIT. +</P> +<P> +The <i>match_limit_recursion</i> field is similar to <i>match_limit</i>, but +instead of limiting the total number of times that <b>match()</b> is called, it +limits the depth of recursion. The recursion depth is a smaller number than the +total number of calls, because not all calls to <b>match()</b> are recursive. +This limit is of use only if it is set smaller than <i>match_limit</i>. +</P> +<P> +Limiting the recursion depth limits the amount of stack that can be used, or, +when PCRE has been compiled to use memory on the heap instead of the stack, the +amount of heap memory that can be used. +</P> +<P> +The default value for <i>match_limit_recursion</i> can be set when PCRE is +built; the default default is the same value as the default for +<i>match_limit</i>. You can override the default by suppling <b>pcre_exec()</b> +with a <b>pcre_extra</b> block in which <i>match_limit_recursion</i> is set, and +PCRE_EXTRA_MATCH_LIMIT_RECURSION is set in the <i>flags</i> field. If the limit +is exceeded, <b>pcre_exec()</b> returns PCRE_ERROR_RECURSIONLIMIT. +</P> +<P> +The <i>pcre_callout</i> field is used in conjunction with the "callout" feature, +which is described in the +<a href="pcrecallout.html"><b>pcrecallout</b></a> +documentation. +</P> +<P> +The <i>tables</i> field is used to pass a character tables pointer to +<b>pcre_exec()</b>; this overrides the value that is stored with the compiled +pattern. A non-NULL value is stored with the compiled pattern only if custom +tables were supplied to <b>pcre_compile()</b> via its <i>tableptr</i> argument. +If NULL is passed to <b>pcre_exec()</b> using this mechanism, it forces PCRE's +internal tables to be used. This facility is helpful when re-using patterns +that have been saved after compiling with an external set of tables, because +the external tables might be at a different address when <b>pcre_exec()</b> is +called. See the +<a href="pcreprecompile.html"><b>pcreprecompile</b></a> +documentation for a discussion of saving compiled patterns for later use. +</P> +<br><b> +Option bits for <b>pcre_exec()</b> +</b><br> +<P> +The unused bits of the <i>options</i> argument for <b>pcre_exec()</b> must be +zero.

If a pattern was compiled with PCRE_ANCHORED, or turned out +to be anchored by virtue of its contents, it cannot be made unachored at +matching time. +<pre> + PCRE_NEWLINE_CR + PCRE_NEWLINE_LF + PCRE_NEWLINE_CRLF +</pre> +These options override the newline definition that was chosen or defaulted when +the pattern was compiled. For details, see the description <b>pcre_compile()</b> +above. During matching, the newline choice affects the behaviour of the dot, +circumflex, and dollar metacharacters. +<pre> + PCRE_NOTBOL +</pre> +This option specifies that first character of the subject string is not the +beginning of a line, so the circumflex metacharacter should not match before +it. Setting this without PCRE_MULTILINE (at compile time) causes circumflex +never to match. This option affects only the behaviour of the circumflex +metacharacter. It does not affect \A. +<pre> + PCRE_NOTEOL +</pre> +This option specifies that the end of the subject string is not the end of a +line, so the dollar metacharacter should not match it nor (except in multiline +mode) a newline immediately before it. Setting this without PCRE_MULTILINE (at +compile time) causes dollar never to match. This option affects only the +behaviour of the dollar metacharacter. It does not affect \Z or \z. +<pre> + PCRE_NOTEMPTY +</pre> +An empty string is not considered to be a valid match if this option is set. If +there are alternatives in the pattern, they are tried. If all the alternatives +match the empty string, the entire match fails. For example, if the pattern +<pre> + a?b? +</pre> +is applied to a string not beginning with "a" or "b", it matches the empty +string at the start of the subject. With PCRE_NOTEMPTY set, this match is not +valid, so PCRE searches further into the string for occurrences of "a" or "b". +</P> +<P> +Perl has no direct equivalent of PCRE_NOTEMPTY, but it does make a special case +of a pattern match of the empty string within its <b>split()</b> function, and +when using the /g modifier. It is possible to emulate Perl's behaviour after +matching a null string by first trying the match again at the same offset with +PCRE_NOTEMPTY and PCRE_ANCHORED, and then if that fails by advancing the +starting offset (see below) and trying an ordinary match again. There is some +code that demonstrates how to do this in the <i>pcredemo.c</i> sample program. +<pre> + PCRE_NO_UTF8_CHECK +</pre> +When PCRE_UTF8 is set at compile time, the validity of the subject as a UTF-8 +string is automatically checked when <b>pcre_exec()</b> is subsequently called. +The value of <i>startoffset</i> is also checked to ensure that it points to the +start of a UTF-8 character. If an invalid UTF-8 sequence of bytes is found, +<b>pcre_exec()</b> returns the error PCRE_ERROR_BADUTF8. If <i>startoffset</i> +contains an invalid value, PCRE_ERROR_BADUTF8_OFFSET is returned. +</P> +<P> +If you already know that your subject is valid, and you want to skip these +checks for performance reasons, you can set the PCRE_NO_UTF8_CHECK option when +calling <b>pcre_exec()</b>. You might want to do this for the second and +subsequent calls to <b>pcre_exec()</b> if you are making repeated calls to find +all the matches in a single subject string. However, you should be sure that +the value of <i>startoffset</i> points to the start of a UTF-8 character. When +PCRE_NO_UTF8_CHECK is set, the effect of passing an invalid UTF-8 string as a +subject, or a value of <i>startoffset</i> that does not point to the start of a +UTF-8 character, is undefined. Your program may crash. +<pre> + PCRE_PARTIAL +</pre> +This option turns on the partial matching feature. If the subject string fails +to match the pattern, but at some point during the matching process the end of +the subject was reached (that is, the subject partially matches the pattern and +the failure to match occurred only because there were not enough subject +characters), <b>pcre_exec()</b> returns PCRE_ERROR_PARTIAL instead of +PCRE_ERROR_NOMATCH. When PCRE_PARTIAL is used, there are restrictions on what +may appear in the pattern. These are discussed in the +<a href="pcrepartial.html"><b>pcrepartial</b></a> +documentation. +</P> +<br><b> +The string to be matched by <b>pcre_exec()</b> +</b><br> +<P> +The subject string is passed to <b>pcre_exec()</b> as a pointer in +<i>subject</i>, a length in <i>length</i>, and a starting byte offset in +<i>startoffset</i>. In UTF-8 mode, the byte offset must point to the start of a +UTF-8 character. Unlike the pattern string, the subject may contain binary zero +bytes. When the starting offset is zero, the search for a match starts at the +beginning of the subject, and this is by far the most common case. +</P> +<P> +A non-zero starting offset is useful when searching for another match in the +same subject by calling <b>pcre_exec()</b> again after a previous success. +Setting <i>startoffset</i> differs from just passing over a shortened string and +setting PCRE_NOTBOL in the case of a pattern that begins with any kind of +lookbehind. For example, consider the pattern +<pre> + \Biss\B +</pre> +which finds occurrences of "iss" in the middle of words. (\B matches only if +the current position in the subject is not a word boundary.) When applied to +the string "Mississipi" the first call to <b>pcre_exec()</b> finds the first +occurrence. If <b>pcre_exec()</b> is called again with just the remainder of the +subject, namely "issipi", it does not match, because \B is always false at the +start of the subject, which is deemed to be a word boundary. However, if +<b>pcre_exec()</b> is passed the entire string again, but with <i>startoffset</i> +set to 4, it finds the second occurrence of "iss" because it is able to look +behind the starting point to discover that it is preceded by a letter. +</P> +<P> +If a non-zero starting offset is passed when the pattern is anchored, one +attempt to match at the given offset is made. This can only succeed if the +pattern does not require the match to be at the start of the subject. +</P> +<br><b> +How <b>pcre_exec()</b> returns captured substrings +</b><br> +<P> +In general, a pattern matches a certain portion of the subject, and in +addition, further substrings from the subject may be picked out by parts of the +pattern. Following the usage in Jeffrey Friedl's book, this is called +"capturing" in what follows, and the phrase "capturing subpattern" is used for +a fragment of a pattern that picks out a substring. PCRE supports several other +kinds of parenthesized subpattern that do not cause substrings to be captured. +</P> +<P> +Captured substrings are returned to the caller via a vector of integer offsets +whose address is passed in <i>ovector</i>. The number of elements in the vector +is passed in <i>ovecsize</i>, which must be a non-negative number. <b>Note</b>: +this argument is NOT the size of <i>ovector</i> in bytes. +</P> +<P> +The first two-thirds of the vector is used to pass back captured substrings, +each substring using a pair of integers. The remaining third of the vector is +used as workspace by <b>pcre_exec()</b> while matching capturing subpatterns, +and is not available for passing back information. The length passed in +<i>ovecsize</i> should always be a multiple of three. If it is not, it is +rounded down. +</P> +<P> +When a match is successful, information about captured substrings is returned +in pairs of integers, starting at the beginning of <i>ovector</i>, and +continuing up to two-thirds of its length at the most. The first element of a +pair is set to the offset of the first character in a substring, and the second +is set to the offset of the first character after the end of a substring. The +first pair, <i>ovector[0]</i> and <i>ovector[1]</i>, identify the portion of the +subject string matched by the entire pattern. The next pair is used for the +first capturing subpattern, and so on. The value returned by <b>pcre_exec()</b> +is one more than the highest numbered pair that has been set. For example, if +two substrings have been captured, the returned value is 3. If there are no +capturing subpatterns, the return value from a successful match is 1, +indicating that just the first pair of offsets has been set. +</P> +<P> +If a capturing subpattern is matched repeatedly, it is the last portion of the +string that it matched that is returned. +</P> +<P> +If the vector is too small to hold all the captured substring offsets, it is +used as far as possible (up to two-thirds of its length), and the function +returns a value of zero. In particular, if the substring offsets are not of +interest, <b>pcre_exec()</b> may be called with <i>ovector</i> passed as NULL and +<i>ovecsize</i> as zero. However, if the pattern contains back references and +the <i>ovector</i> is not big enough to remember the related substrings, PCRE +has to get additional memory for use during matching. Thus it is usually +advisable to supply an <i>ovector</i>. +</P> +<P> +The <b>pcre_info()</b> function can be used to find out how many capturing +subpatterns there are in a compiled pattern. The smallest size for +<i>ovector</i> that will allow for <i>n</i> captured substrings, in addition to +the offsets of the substring matched by the whole pattern, is (<i>n</i>+1)*3. +</P> +<P> +It is possible for capturing subpattern number <i>n+1</i> to match some part of +the subject when subpattern <i>n</i> has not been used at all. For example, if +the string "abc" is matched against the pattern (a|(z))(bc) the return from the +function is 4, and subpatterns 1 and 3 are matched, but 2 is not. When this +happens, both values in the offset pairs corresponding to unused subpatterns +are set to -1. +</P> +<P> +Offset values that correspond to unused subpatterns at the end of the +expression are also set to -1. For example, if the string "abc" is matched +against the pattern (abc)(x(yz)?)? subpatterns 2 and 3 are not matched. The +return from the function is 2, because the highest used capturing subpattern +number is 1. However, you can refer to the offsets for the second and third +capturing subpatterns if you wish (assuming the vector is large enough, of +course). +</P> +<P> +Some convenience functions are provided for extracting the captured substrings +as separate strings.

They are all selected, or deselected, by providing +options to the <b>configure</b> script that is run before the <b>make</b> +command. The complete list of options for <b>configure</b> (which includes the +standard ones such as the selection of the installation directory) can be +obtained by running +<pre> + ./configure --help +</pre> +The following sections describe certain options whose names begin with --enable +or --disable. These settings specify changes to the defaults for the +<b>configure</b> command. Because of the way that <b>configure</b> works, +--enable and --disable always come in pairs, so the complementary option always +exists as well, but as it specifies the default, it is not described. +</P> +<br><a name="SEC2" href="#TOC1">C++ SUPPORT</a><br> +<P> +By default, the <b>configure</b> script will search for a C++ compiler and C++ +header files.

You can disable this by adding +<pre> + --disable-cpp +</pre> +to the <b>configure</b> command. +</P> +<br><a name="SEC3" href="#TOC1">UTF-8 SUPPORT</a><br> +<P> +To build PCRE with support for UTF-8 character strings, add +<pre> + --enable-utf8 +</pre> +to the <b>configure</b> command. Of itself, this does not make PCRE treat +strings as UTF-8. As well as compiling PCRE with this option, you also have +have to set the PCRE_UTF8 option when you call the <b>pcre_compile()</b> +function. +</P> +<br><a name="SEC4" href="#TOC1">UNICODE CHARACTER PROPERTY SUPPORT</a><br> +<P> +UTF-8 support allows PCRE to process character values greater than 255 in the +strings that it handles. On its own, however, it does not provide any +facilities for accessing the properties of such characters. If you want to be +able to use the pattern escapes \P, \p, and \X, which refer to Unicode +character properties, you must add +<pre> + --enable-unicode-properties +</pre> +to the <b>configure</b> command. This implies UTF-8 support, even if you have +not explicitly requested it. +</P> +<P> +Including Unicode property support adds around 90K of tables to the PCRE +library, approximately doubling its size. Only the general category properties +such as <i>Lu</i> and <i>Nd</i> are supported. Details are given in the +<a href="pcrepattern.html"><b>pcrepattern</b></a> +documentation. +</P> +<br><a name="SEC5" href="#TOC1">CODE VALUE OF NEWLINE</a><br> +<P> +By default, PCRE interprets character 10 (linefeed, LF) as indicating the end +of a line. This is the normal newline character on Unix-like systems. You can +compile PCRE to use character 13 (carriage return, CR) instead, by adding +<pre> + --enable-newline-is-cr +</pre> +to the <b>configure</b> command. There is also a --enable-newline-is-lf option, +which explicitly specifies linefeed as the newline character. +<br> +<br> +Alternatively, you can specify that line endings are to be indicated by the two +character sequence CRLF. If you want this, add +<pre> + --enable-newline-is-crlf +</pre> +to the <b>configure</b> command. Whatever line ending convention is selected +when PCRE is built can be overridden when the library functions are called. At +build time it is conventional to use the standard for your operating system. +</P> +<br><a name="SEC6" href="#TOC1">BUILDING SHARED AND STATIC LIBRARIES</a><br> +<P> +The PCRE building process uses <b>libtool</b> to build both shared and static +Unix libraries by default. You can suppress one of these by adding one of +<pre> + --disable-shared + --disable-static +</pre> +to the <b>configure</b> command, as required. +</P> +<br><a name="SEC7" href="#TOC1">POSIX MALLOC USAGE</a><br> +<P> +When PCRE is called through the POSIX interface (see the +<a href="pcreposix.html"><b>pcreposix</b></a> +documentation), additional working storage is required for holding the pointers +to capturing substrings, because PCRE requires three integers per substring, +whereas the POSIX interface provides only two. If the number of expected +substrings is small, the wrapper function uses space on the stack, because this +is faster than using <b>malloc()</b> for each call. The default threshold above +which the stack is no longer used is 10; it can be changed by adding a setting +such as +<pre> + --with-posix-malloc-threshold=20 +</pre> +to the <b>configure</b> command. +</P> +<br><a name="SEC8" href="#TOC1">HANDLING VERY LARGE PATTERNS</a><br> +<P> +Within a compiled pattern, offset values are used to point from one part to +another (for example, from an opening parenthesis to an alternation +metacharacter). By default, two-byte values are used for these offsets, leading +to a maximum size for a compiled pattern of around 64K. This is sufficient to +handle all but the most gigantic patterns. Nevertheless, some people do want to +process enormous patterns, so it is possible to compile PCRE to use three-byte +or four-byte offsets by adding a setting such as +<pre> + --with-link-size=3 +</pre> +to the <b>configure</b> command. The value given must be 2, 3, or 4. Using +longer offsets slows down the operation of PCRE because it has to load +additional bytes when handling them. +</P> +<P> +If you build PCRE with an increased link size, test 2 (and test 5 if you are +using UTF-8) will fail. Part of the output of these tests is a representation +of the compiled pattern, and this changes with the link size. +</P> +<br><a name="SEC9" href="#TOC1">AVOIDING EXCESSIVE STACK USAGE</a><br> +<P> +When matching with the <b>pcre_exec()</b> function, PCRE implements backtracking +by making recursive calls to an internal function called <b>match()</b>. In +environments where the size of the stack is limited, this can severely limit +PCRE's operation. (The Unix environment does not usually suffer from this +problem, but it may sometimes be necessary to increase the maximum stack size. +There is a discussion in the +<a href="pcrestack.html"><b>pcrestack</b></a> +documentation.) An alternative approach to recursion that uses memory from the +heap to remember data, instead of using recursive function calls, has been +implemented to work round the problem of limited stack size. If you want to +build a version of PCRE that works this way, add +<pre> + --disable-stack-for-recursion +</pre> +to the <b>configure</b> command. With this configuration, PCRE will use the +<b>pcre_stack_malloc</b> and <b>pcre_stack_free</b> variables to call memory +management functions. Separate functions are provided because the usage is very +predictable: the block sizes requested are always the same, and the blocks are +always freed in reverse order. A calling program might be able to implement +optimized functions that perform better than the standard <b>malloc()</b> and +<b>free()</b> functions. PCRE runs noticeably more slowly when built in this +way. This option affects only the <b>pcre_exec()</b> function; it is not +relevant for the the <b>pcre_dfa_exec()</b> function. +</P> +<br><a name="SEC10" href="#TOC1">LIMITING PCRE RESOURCE USAGE</a><br> +<P> +Internally, PCRE has a function called <b>match()</b>, which it calls repeatedly +(sometimes recursively) when matching a pattern with the <b>pcre_exec()</b> +function. By controlling the maximum number of times this function may be +called during a single matching operation, a limit can be placed on the +resources used by a single call to <b>pcre_exec()</b>. The limit can be changed +at run time, as described in the +<a href="pcreapi.html"><b>pcreapi</b></a> +documentation. The default is 10 million, but this can be changed by adding a +setting such as +<pre> + --with-match-limit=500000 +</pre> +to the <b>configure</b> command. This setting has no effect on the +<b>pcre_dfa_exec()</b> matching function. +</P> +<P> +In some environments it is desirable to limit the depth of recursive calls of +<b>match()</b> more strictly than the total number of calls, in order to +restrict the maximum amount of stack (or heap, if --disable-stack-for-recursion +is specified) that is used. A second limit controls this; it defaults to the +value that is set for --with-match-limit, which imposes no additional +constraints. However, you can set a lower limit by adding, for example, +<pre> + --with-match-limit-recursion=10000 +</pre> +to the <b>configure</b> command. This value can also be overridden at run time. +</P> +<br><a name="SEC11" href="#TOC1">USING EBCDIC CODE</a><br> +<P> +PCRE assumes by default that it will run in an environment where the character +code is ASCII (or Unicode, which is a superset of ASCII).

The differences described here are with respect to Perl +5.8. +</P> +<P> +1. PCRE has only a subset of Perl's UTF-8 and Unicode support. Details of what +it does have are given in the +<a href="pcre.html#utf8support">section on UTF-8 support</a> +in the main +<a href="pcre.html"><b>pcre</b></a> +page. +</P> +<P> +2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl permits +them, but they do not mean what you might think. For example, (?!a){3} does +not assert that the next three characters are not "a". It just asserts that the +next character is not "a" three times. +</P> +<P> +3. Capturing subpatterns that occur inside negative lookahead assertions are +counted, but their entries in the offsets vector are never set. Perl sets its +numerical variables from any such patterns that are matched before the +assertion fails to match something (thereby succeeding), but only if the +negative lookahead assertion contains just one branch. +</P> +<P> +4. Though binary zero characters are supported in the subject string, they are +not allowed in a pattern string because it is passed as a normal C string, +terminated by zero. The escape sequence \0 can be used in the pattern to +represent a binary zero. +</P> +<P> +5. The following Perl escape sequences are not supported: \l, \u, \L, +\U, and \N. In fact these are implemented by Perl's general string-handling +and are not part of its pattern matching engine. If any of these are +encountered by PCRE, an error is generated. +</P> +<P> +6. The Perl escape sequences \p, \P, and \X are supported only if PCRE is +built with Unicode character property support. The properties that can be +tested with \p and \P are limited to the general category properties such as +Lu and Nd, script names such as Greek or Han, and the derived properties Any +and L&. +</P> +<P> +7. PCRE does support the \Q...\E escape for quoting substrings. Characters in +between are treated as literals. This is slightly different from Perl in that $ +and @ are also handled as literals inside the quotes. In Perl, they cause +variable interpolation (but of course PCRE does not have variables). Note the +following examples: +<pre> + Pattern PCRE matches Perl matches + + \Qabc$xyz\E abc$xyz abc followed by the contents of $xyz + \Qabc\$xyz\E abc\$xyz abc\$xyz + \Qabc\E\$\Qxyz\E abc$xyz abc$xyz +</pre> +The \Q...\E sequence is recognized both inside and outside character classes. +</P> +<P> +8. Fairly obviously, PCRE does not support the (?{code}) and (?p{code}) +constructions. However, there is support for recursive patterns using the +non-Perl items (?R), (?number), and (?P>name). Also, the PCRE "callout" feature +allows an external function to be called during pattern matching. See the +<a href="pcrecallout.html"><b>pcrecallout</b></a> +documentation for details. +</P> +<P> +9. There are some differences that are concerned with the settings of captured +strings when part of a pattern is repeated. For example, matching "aba" against +the pattern /^(a(b)?)+$/ in Perl leaves $2 unset, but in PCRE it is set to "b". +</P> +<P> +10. PCRE provides some extensions to the Perl regular expression facilities: +<br> +<br> +(a) Although lookbehind assertions must match fixed length strings, each +alternative branch of a lookbehind assertion can match a different length of +string. Perl requires them all to have the same length. +<br> +<br> +(b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not set, the $ +meta-character matches only at the very end of the string. +<br> +<br> +(c) If PCRE_EXTRA is set, a backslash followed by a letter with no special +meaning is faulted. Otherwise, like Perl, the backslash is ignored. (Perl can +be made to issue a warning.) +<br> +<br> +(d) If PCRE_UNGREEDY is set, the greediness of the repetition quantifiers is +inverted, that is, by default they are not greedy, but if followed by a +question mark they are. +<br> +<br> +(e) PCRE_ANCHORED can be used at matching time to force a pattern to be tried +only at the first matching position in the subject string. +<br> +<br> +(f) The PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, and PCRE_NO_AUTO_CAPTURE +options for <b>pcre_exec()</b> have no Perl equivalents. +<br> +<br> +(g) The (?R), (?number), and (?P>name) constructs allows for recursive pattern +matching (Perl can do this using the (?p{code}) construct, which PCRE cannot +support.) +<br> +<br> +(h) PCRE supports named capturing substrings, using the Python syntax. +<br> +<br> +(i) PCRE supports the possessive quantifier "++" syntax, taken from Sun's Java +package. +<br> +<br> +(j) The (R) condition, for testing recursion, is a PCRE extension. +<br> +<br> +(k) The callout facility is PCRE-specific. +<br> +<br> +(l) The partial matching facility is PCRE-specific. +<br> +<br> +(m) Patterns compiled by PCRE can be saved and re-used at a later time, even on +different hosts that have the other endianness. +<br> +<br> +(n) The alternative matching function (<b>pcre_dfa_exec()</b>) matches in a +different way and is not Perl-compatible. +</P> +<P> +Last updated: 06 June 2006 +<br> +Copyright © 1997-2006 University of Cambridge. +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> Added: freeswitch/trunk/libs/pcre/doc/html/pcrecpp.html ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/doc/html/pcrecpp.html Tue Dec 19 14:54:26 2006 @@ -0,0 +1,337 @@ +<html> +<head> +<title>pcrecpp specification</title> +</head> +<body bgcolor="#FFFFFF" text="#00005A" link="#0066FF" alink="#3399FF" vlink="#2222BB"> +<h1>pcrecpp man page</h1> +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> +<p> +This page is part of the PCRE HTML documentation.

The examples below +tend to use a const char*. You can, as in the different examples above, store +the RE object explicitly in a variable or use a temporary RE object. The +examples below use one mode or the other arbitrarily. Either could correctly be +used for any of these examples. +</P> +<P> +You must supply extra pointer arguments to extract matched subpieces. +<pre> + Example: extracts "ruby" into "s" and 1234 into "i" + int i; + string s; + pcrecpp::RE re("(\\w+):(\\d+)"); + re.FullMatch("ruby:1234", &s, &i); + + Example: does not try to extract any extra sub-patterns + re.FullMatch("ruby:1234", &s); + + Example: does not try to extract into NULL + re.FullMatch("ruby:1234", NULL, &i); + + Example: integer overflow causes failure + !re.FullMatch("ruby:1234567891234", NULL, &i); + + Example: fails because there aren't enough sub-patterns: + !pcrecpp::RE("\\w+:\\d+").FullMatch("ruby:1234", &s); + + Example: fails because string cannot be stored in integer + !pcrecpp::RE("(.*)").FullMatch("ruby", &i); +</pre> +The provided pointer arguments can be pointers to any scalar numeric +type, or one of: +<pre> + string (matched piece is copied to string) + StringPiece (StringPiece is mutated to point to matched piece) + T (where "bool T::ParseFrom(const char*, int)" exists) + NULL (the corresponding matched sub-pattern is not copied) +</pre> +The function returns true iff all of the following conditions are satisfied: +<pre> + a. "text" matches "pattern" exactly; + + b. The number of matched sub-patterns is >= number of supplied + pointers; + + c. The "i"th argument has a suitable type for holding the + string captured as the "i"th sub-pattern. If you pass in + NULL for the "i"th argument, or pass fewer arguments than + number of sub-patterns, "i"th captured sub-pattern is + ignored. +</pre> +The matching interface supports at most 16 arguments per call. +If you need more, consider using the more general interface +<b>pcrecpp::RE::DoMatch</b>. See <b>pcrecpp.h</b> for the signature for +<b>DoMatch</b>. +</P> +<br><a name="SEC4" href="#TOC1">PARTIAL MATCHES</a><br> +<P> +You can use the "PartialMatch" operation when you want the pattern +to match any substring of the text. +<pre> + Example: simple search for a string: + pcrecpp::RE("ell").PartialMatch("hello"); + + Example: find first number in a string: + int number; + pcrecpp::RE re("(\\d+)"); + re.PartialMatch("x*100 + 20", &number); + assert(number == 100); +</PRE> +</P> +<br><a name="SEC5" href="#TOC1">UTF-8 AND THE MATCHING INTERFACE</a><br> +<P> +By default, pattern and text are plain text, one byte per character. The UTF8 +flag, passed to the constructor, causes both pattern and string to be treated +as UTF-8 text, still a byte stream but potentially multiple bytes per +character. In practice, the text is likelier to be UTF-8 than the pattern, but +the match returned may depend on the UTF8 flag, so always use it when matching +UTF8 text. For example, "." will match one byte normally but with UTF8 set may +match up to three bytes of a multi-byte character. +<pre> + Example: + pcrecpp::RE_Options options; + options.set_utf8(); + pcrecpp::RE re(utf8_pattern, options); + re.FullMatch(utf8_string); + + Example: using the convenience function UTF8(): + pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8()); + re.FullMatch(utf8_string); +</pre> +NOTE: The UTF8 flag is ignored if pcre was not configured with the +<pre> + --enable-utf8 flag. +</PRE> +</P> +<br><a name="SEC6" href="#TOC1">PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE</a><br> +<P> +PCRE defines some modifiers to change the behavior of the regular expression +engine. The C++ wrapper defines an auxiliary class, RE_Options, as a vehicle to +pass such modifiers to a RE class. Currently, the following modifiers are +supported: +<pre> + modifier description Perl corresponding + + PCRE_CASELESS case insensitive match /i + PCRE_MULTILINE multiple lines match /m + PCRE_DOTALL dot matches newlines /s + PCRE_DOLLAR_ENDONLY $ matches only at end N/A + PCRE_EXTRA strict escape parsing N/A + PCRE_EXTENDED ignore whitespaces /x + PCRE_UTF8 handles UTF8 chars built-in + PCRE_UNGREEDY reverses * and *? N/A + PCRE_NO_AUTO_CAPTURE disables capturing parens N/A (*) +</pre> +(*) Both Perl and PCRE allow non capturing parentheses by means of the +"?:" modifier within the pattern itself. e.g. (?:ab|cd) does not +capture, while (ab|cd) does. +</P> +<P> +For a full account on how each modifier works, please check the +PCRE API reference page. +</P> +<P> +For each modifier, there are two member functions whose name is made +out of the modifier in lowercase, without the "PCRE_" prefix. For +instance, PCRE_CASELESS is handled by +<pre> + bool caseless() +</pre> +which returns true if the modifier is set, and +<pre> + RE_Options & set_caseless(bool) +</pre> +which sets or unsets the modifier. Moreover, PCRE_EXTRA_MATCH_LIMIT can be +accessed through the <b>set_match_limit()</b> and <b>match_limit()</b> member +functions. Setting <i>match_limit</i> to a non-zero value will limit the +execution of pcre to keep it from doing bad things like blowing the stack or +taking an eternity to return a result. A value of 5000 is good enough to stop +stack blowup in a 2MB thread stack. Setting <i>match_limit</i> to zero disables +match limiting. Alternatively, you can call <b>match_limit_recursion()</b> +which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to limit how much PCRE +recurses. <b>match_limit()</b> limits the number of matches PCRE does; +<b>match_limit_recursion()</b> limits the depth of internal recursion, and +therefore the amount of stack that is used. +</P> +<P> +Normally, to pass one or more modifiers to a RE class, you declare +a <i>RE_Options</i> object, set the appropriate options, and pass this +object to a RE constructor. Example: +<pre> + RE_options opt; + opt.set_caseless(true); + if (RE("HELLO", opt).PartialMatch("hello world")) ... +</pre> +RE_options has two constructors. The default constructor takes no arguments and +creates a set of flags that are off by default. The optional parameter +<i>option_flags</i> is to facilitate transfer of legacy code from C programs. +This lets you do +<pre> + RE(pattern, + RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str); +</pre> +However, new code is better off doing +<pre> + RE(pattern, + RE_Options().set_caseless(true).set_multiline(true)) + .PartialMatch(str); +</pre> +If you are going to pass one of the most used modifiers, there are some +convenience functions that return a RE_Options class with the +appropriate modifier already set: <b>CASELESS()</b>, <b>UTF8()</b>, +<b>MULTILINE()</b>, <b>DOTALL</b>(), and <b>EXTENDED()</b>. +</P> +<P> +If you need to set several options at once, and you don't want to go through +the pains of declaring a RE_Options object and setting several options, there +is a parallel method that give you such ability on the fly. You can concatenate +several <b>set_xxxxx()</b> member functions, since each of them returns a +reference to its class object. For example, to pass PCRE_CASELESS, +PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one statement, you may write: +<pre> + RE(" ^ xyz \\s+ .* blah$", + RE_Options() + .set_caseless(true) + .set_extended(true) + .set_multiline(true)).PartialMatch(sometext); + +</PRE> +</P> +<br><a name="SEC7" href="#TOC1">SCANNING TEXT INCREMENTALLY</a><br> +<P> +The "Consume" operation may be useful if you want to repeatedly +match regular expressions at the front of a string and skip over +them as they match. This requires use of the "StringPiece" type, +which represents a sub-range of a real string. Like RE, StringPiece +is defined in the pcrecpp namespace. +<pre> + Example: read lines of the form "var = value" from a string. + string contents = ...; // Fill string somehow + pcrecpp::StringPiece input(contents); // Wrap in a StringPiece +</PRE> +</P> +<P> +<pre> + string var; + int value; + pcrecpp::RE re("(\\w+) = (\\d+)\n"); + while (re.Consume(&input, &var, &value)) { + ...; + } +</pre> +Each successful call to "Consume" will set "var/value", and also +advance "input" so it points past the matched text. +</P> +<P> +The "FindAndConsume" operation is similar to "Consume" but does not +anchor your match at the beginning of the string. For example, you +could extract all words from a string by repeatedly calling +<pre> + pcrecpp::RE("(\\w+)").FindAndConsume(&input, &word) +</PRE> +</P> +<br><a name="SEC8" href="#TOC1">PARSING HEX/OCTAL/C-RADIX NUMBERS</a><br> +<P> +By default, if you pass a pointer to a numeric value, the +corresponding text is interpreted as a base-10 number. You can +instead wrap the pointer with a call to one of the operators Hex(), +Octal(), or CRadix() to interpret the text in another base. The +CRadix operator interprets C-style "0" (base-8) and "0x" (base-16) +prefixes, but defaults to base-10. +<pre> + Example: + int a, b, c, d; + pcrecpp::RE re("(.*) (.*) (.*) (.*)"); + re.FullMatch("100 40 0100 0x40", + pcrecpp::Octal(&a), pcrecpp::Hex(&b), + pcrecpp::CRadix(&c), pcrecpp::CRadix(&d)); +</pre> +will leave 64 in a, b, c, and d. +</P> +<br><a name="SEC9" href="#TOC1">REPLACING PARTS OF STRINGS</a><br> +<P> +You can replace the first match of "pattern" in "str" with "rewrite". +Within "rewrite", backslash-escaped digits (\1 to \9) can be +used to insert text matching corresponding parenthesized group +from the pattern. \0 in "rewrite" refers to the entire matching +text. For example: +<pre> + string s = "yabba dabba doo"; + pcrecpp::RE("b+").Replace("d", &s); +</pre> +will leave "s" containing "yada dabba doo". The result is true if the pattern +matches and a replacement occurs, false otherwise. +</P> +<P> +<b>GlobalReplace</b> is like <b>Replace</b> except that it replaces all +occurrences of the pattern in the string with the rewrite. Replacements are +not subject to re-matching. For example: +<pre> + string s = "yabba dabba doo"; + pcrecpp::RE("b+").GlobalReplace("d", &s); +</pre> +will leave "s" containing "yada dada doo". It returns the number of +replacements made. +</P> +<P> +<b>Extract</b> is like <b>Replace</b>, except that if the pattern matches, +"rewrite" is copied into "out" (an additional argument) with substitutions. +The non-matching portions of "text" are ignored. Returns true iff a match +occurred and the extraction happened successfully; if no match occurs, the +string is left unaffected. +</P> +<br><a name="SEC10" href="#TOC1">AUTHOR</a><br> +<P> +The C++ wrapper was contributed by Google Inc. +<br> +Copyright © 2005 Google Inc. +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> Added: freeswitch/trunk/libs/pcre/doc/html/pcregrep.html ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/doc/html/pcregrep.html Tue Dec 19 14:54:26 2006 @@ -0,0 +1,424 @@ +<html> +<head> +<title>pcregrep specification</title> +</head> +<body bgcolor="#FFFFFF" text="#00005A" link="#0066FF" alink="#3399FF" vlink="#2222BB"> +<h1>pcregrep man page</h1> +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> +<p> +This page is part of the PCRE HTML documentation.

The +"standard" algorithm is the one provided by the <b>pcre_exec()</b> function. +This works in the same was as Perl's matching function, and provides a +Perl-compatible matching operation. +</P> +<P> +An alternative algorithm is provided by the <b>pcre_dfa_exec()</b> function; +this operates in a different way, and is not Perl-compatible. It has advantages +and disadvantages compared with the standard algorithm, and these are described +below. +</P> +<P> +When there is only one possible way in which a given subject string can match a +pattern, the two algorithms give the same answer. A difference arises, however, +when there are multiple possibilities. For example, if the pattern +<pre> + ^<.*> +</pre> +is matched against the string +<pre> + <something> <something else> <something further> +</pre> +there are three possible answers. The standard algorithm finds only one of +them, whereas the DFA algorithm finds all three. +</P> +<br><a name="SEC2" href="#TOC1">REGULAR EXPRESSIONS AS TREES</a><br> +<P> +The set of strings that are matched by a regular expression can be represented +as a tree structure. An unlimited repetition in the pattern makes the tree of +infinite size, but it is still a tree. Matching the pattern to a given subject +string (from a given starting point) can be thought of as a search of the tree. +There are two ways to search a tree: depth-first and breadth-first, and these +correspond to the two matching algorithms provided by PCRE. +</P> +<br><a name="SEC3" href="#TOC1">THE STANDARD MATCHING ALGORITHM</a><br> +<P> +In the terminology of Jeffrey Friedl's book \fIMastering Regular +Expressions\fP, the standard algorithm is an "NFA algorithm". It conducts a +depth-first search of the pattern tree. That is, it proceeds along a single +path through the tree, checking that the subject matches what is required. When +there is a mismatch, the algorithm tries any alternatives at the current point, +and if they all fail, it backs up to the previous branch point in the tree, and +tries the next alternative branch at that level. This often involves backing up +(moving to the left) in the subject string as well. The order in which +repetition branches are tried is controlled by the greedy or ungreedy nature of +the quantifier. +</P> +<P> +If a leaf node is reached, a matching string has been found, and at that point +the algorithm stops. Thus, if there is more than one possible match, this +algorithm returns the first one that it finds. Whether this is the shortest, +the longest, or some intermediate length depends on the way the greedy and +ungreedy repetition quantifiers are specified in the pattern. +</P> +<P> +Because it ends up with a single path through the tree, it is relatively +straightforward for this algorithm to keep track of the substrings that are +matched by portions of the pattern in parentheses. This provides support for +capturing parentheses and back references. +</P> +<br><a name="SEC4" href="#TOC1">THE DFA MATCHING ALGORITHM</a><br> +<P> +DFA stands for "deterministic finite automaton", but you do not need to +understand the origins of that name. This algorithm conducts a breadth-first +search of the tree. Starting from the first matching point in the subject, it +scans the subject string from left to right, once, character by character, and +as it does this, it remembers all the paths through the tree that represent +valid matches. +</P> +<P> +The scan continues until either the end of the subject is reached, or there are +no more unterminated paths. At this point, terminated paths represent the +different matching possibilities (if there are none, the match has failed). +Thus, if there is more than one possible match, this algorithm finds all of +them, and in particular, it finds the longest. In PCRE, there is an option to +stop the algorithm after the first match (which is necessarily the shortest) +has been found. +</P> +<P> +Note that all the matches that are found start at the same point in the +subject. If the pattern +<pre> + cat(er(pillar)?) +</pre> +is matched against the string "the caterpillar catchment", the result will be +the three strings "cat", "cater", and "caterpillar" that start at the fourth +character of the subject. The algorithm does not automatically move on to find +matches that start at later positions. +</P> +<P> +There are a number of features of PCRE regular expressions that are not +supported by the DFA matching algorithm. They are as follows: +</P> +<P> +1. Because the algorithm finds all possible matches, the greedy or ungreedy +nature of repetition quantifiers is not relevant. Greedy and ungreedy +quantifiers are treated in exactly the same way. +</P> +<P> +2. When dealing with multiple paths through the tree simultaneously, it is not +straightforward to keep track of captured substrings for the different matching +possibilities, and PCRE's implementation of this algorithm does not attempt to +do this. This means that no captured substrings are available. +</P> +<P> +3. Because no substrings are captured, back references within the pattern are +not supported, and cause errors if encountered. +</P> +<P> +4. For the same reason, conditional expressions that use a backreference as the +condition are not supported. +</P> +<P> +5. Callouts are supported, but the value of the <i>capture_top</i> field is +always 1, and the value of the <i>capture_last</i> field is always -1. +</P> +<P> +6. +The \C escape sequence, which (in the standard algorithm) matches a single +byte, even in UTF-8 mode, is not supported because the DFA algorithm moves +through the subject string one character at a time, for all active paths +through the tree. +</P> +<br><a name="SEC5" href="#TOC1">ADVANTAGES OF THE DFA ALGORITHM</a><br> +<P> +Using the DFA matching algorithm provides the following advantages: +</P> +<P> +1. All possible matches (at a single point in the subject) are automatically +found, and in particular, the longest match is found. To find more than one +match using the standard algorithm, you have to do kludgy things with +callouts. +</P> +<P> +2. There is much better support for partial matching. The restrictions on the +content of the pattern that apply when using the standard algorithm for partial +matching do not apply to the DFA algorithm. For non-anchored patterns, the +starting position of a partial match is available. +</P> +<P> +3. Because the DFA algorithm scans the subject string just once, and never +needs to backtrack, it is possible to pass very long subject strings to the +matching function in several pieces, checking for partial matching each time. +</P> +<br><a name="SEC6" href="#TOC1">DISADVANTAGES OF THE DFA ALGORITHM</a><br> +<P> +The DFA algorithm suffers from a number of disadvantages: +</P> +<P> +1. It is substantially slower than the standard algorithm. This is partly +because it has to search for all possible matches, but is also because it is +less susceptible to optimization. +</P> +<P> +2. Capturing parentheses and back references are not supported. +</P> +<P> +3. The "atomic group" feature of PCRE regular expressions is supported, but +does not provide the advantage that it does for the standard algorithm. +</P> +<P> +Last updated: 06 June 2006 +<br> +Copyright © 1997-2006 University of Cambridge. +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> Added: freeswitch/trunk/libs/pcre/doc/html/pcrepartial.html ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/doc/html/pcrepartial.html Tue Dec 19 14:54:26 2006 @@ -0,0 +1,225 @@ +<html> +<head> +<title>pcrepartial specification</title> +</head> +<body bgcolor="#FFFFFF" text="#00005A" link="#0066FF" alink="#3399FF" vlink="#2222BB"> +<h1>pcrepartial man page</h1> +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> +<p> +This page is part of the PCRE HTML documentation.

Here is a run of <b>pcretest</b> that +uses the date example quoted above: +<pre> + re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/ + data> 25jun04\P + 0: 25jun04 + 1: jun + data> 25dec3\P + Partial match + data> 3ju\P + Partial match + data> 3juj\P + No match + data> j\P + No match +</pre> +The first data string is matched completely, so <b>pcretest</b> shows the +matched substrings.

Here is +an example using <b>pcretest</b>, where the \R escape sequence sets the +PCRE_DFA_RESTART option and the \D escape sequence requests the use of +<b>pcre_dfa_exec()</b>: +<pre> + re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/ + data> 23ja\P\D + Partial match: 23ja + data> n05\R\D + 0: n05 +</pre> +The first call has "23ja" as the subject, and requests partial matching; the +second call has "n05" as the subject for the continued (restarted) match. +Notice that when the match is complete, only the last part is shown; PCRE does +not retain the previously partially-matched string. It is up to the calling +program to do that if it needs to. +</P> +<P> +This facility can be used to pass very long subject strings to +<b>pcre_dfa_exec()</b>. However, some care is needed for certain types of +pattern. +</P> +<P> +1. If the pattern contains tests for the beginning or end of a line, you need +to pass the PCRE_NOTBOL or PCRE_NOTEOL options, as appropriate, when the +subject string for any call does not contain the beginning or end of a line. +</P> +<P> +2. If the pattern contains backward assertions (including \b or \B), you need +to arrange for some overlap in the subject strings to allow for this. For +example, you could pass the subject in chunks that were 500 bytes long, but in +a buffer of 700 bytes, with the starting offset set to 200 and the previous 200 +bytes at the start of the buffer. +</P> +<P> +3. Matching a subject string that is split into multiple segments does not +always produce exactly the same result as matching over one single long string. +The difference arises when there are multiple matching possibilities, because a +partial match result is given only when there are no completed matches in a +call to fBpcre_dfa_exec()\fP. This means that as soon as the shortest match has +been found, continuation to a new subject segment is no longer possible. +Consider this <b>pcretest</b> example: +<pre> + re> /dog(sbody)?/ + data> do\P\D + Partial match: do + data> gsb\R\P\D + 0: g + data> dogsbody\D + 0: dogsbody + 1: dog +</pre> +The pattern matches the words "dog" or "dogsbody". When the subject is +presented in several parts ("do" and "gsb" being the first two) the match stops +when "dog" has been found, and it is not possible to continue. On the other +hand, if "dogsbody" is presented as a single string, both matches are found. +</P> +<P> +Because of this phenomenon, it does not usually make sense to end a pattern +that is going to be matched in this way with a variable repeat. +</P> +<P> +4. Patterns that contain alternatives at the top level which do not all +start with the same pattern item may not work as expected. For example, +consider this pattern: +<pre> + 1234|3789 +</pre> +If the first part of the subject is "ABC123", a partial match of the first +alternative is found at offset 3. There is no partial match for the second +alternative, because such a match does not start at the same point in the +subject string. Attempting to continue with the string "789" does not yield a +match because only those alternatives that match at one point in the subject +are remembered. The problem arises because the start of the second alternative +matches within the first alternative.

Regular expressions are also described in the Perl +documentation and in a number of books, some of which have copious examples. +Jeffrey Friedl's "Mastering Regular Expressions", published by O'Reilly, covers +regular expressions in great detail. This description of PCRE's regular +expressions is intended as reference material. +</P> +<P> +The original operation of PCRE was on strings of one-byte characters. However, +there is now also support for UTF-8 character strings. To use this, you must +build PCRE to include UTF-8 support, and then call <b>pcre_compile()</b> with +the PCRE_UTF8 option. How this affects pattern matching is mentioned in several +places below. There is also a summary of UTF-8 features in the +<a href="pcre.html#utf8support">section on UTF-8 support</a> +in the main +<a href="pcre.html"><b>pcre</b></a> +page. +</P> +<P> +The remainder of this document discusses the patterns that are supported by +PCRE when its main matching function, <b>pcre_exec()</b>, is used. +From release 6.0, PCRE offers a second matching function, +<b>pcre_dfa_exec()</b>, which matches using a different algorithm that is not +Perl-compatible. The advantages and disadvantages of the alternative function, +and how it differs from the normal function, are discussed in the +<a href="pcrematching.html"><b>pcrematching</b></a> +page. +</P> +<P> +A regular expression is a pattern that is matched against a subject string from +left to right. Most characters stand for themselves in a pattern, and match the +corresponding characters in the subject. As a trivial example, the pattern +<pre> + The quick brown fox +</pre> +matches a portion of a subject string that is identical to itself. When +caseless matching is specified (the PCRE_CASELESS option), letters are matched +independently of case. In UTF-8 mode, PCRE always understands the concept of +case for characters whose values are less than 128, so caseless matching is +always possible. For characters with higher values, the concept of case is +supported if PCRE is compiled with Unicode property support, but not otherwise. +If you want to use caseless matching for characters 128 and above, you must +ensure that PCRE is compiled with Unicode property support as well as with +UTF-8 support. +</P> +<P> +The power of regular expressions comes from the ability to include alternatives +and repetitions in the pattern. These are encoded in the pattern by the use of +<i>metacharacters</i>, which do not stand for themselves but instead are +interpreted in some special way. +</P> +<P> +There are two different sets of metacharacters: those that are recognized +anywhere in the pattern except within square brackets, and those that are +recognized in square brackets. Outside square brackets, the metacharacters are +as follows: +<pre> + \ general escape character with several uses + ^ assert start of string (or line, in multiline mode) + $ assert end of string (or line, in multiline mode) + . match any character except newline (by default) + [ start character class definition + | start of alternative branch + ( start subpattern + ) end subpattern + ? extends the meaning of ( + also 0 or 1 quantifier + also quantifier minimizer + * 0 or more quantifier + + 1 or more quantifier + also "possessive quantifier" + { start min/max quantifier +</pre> +Part of a pattern that is in square brackets is called a "character class". In +a character class the only metacharacters are: +<pre> + \ general escape character + ^ negate the class, but only if the first character + - indicates character range + [ POSIX character class (only if followed by POSIX syntax) + ] terminates the character class +</pre> +The following sections describe the use of each of the metacharacters. +</P> +<br><a name="SEC2" href="#TOC1">BACKSLASH</a><br> +<P> +The backslash character has several uses. Firstly, if it is followed by a +non-alphanumeric character, it takes away any special meaning that character +may have. This use of backslash as an escape character applies both inside and +outside character classes. +</P> +<P> +For example, if you want to match a * character, you write \* in the pattern. +This escaping action applies whether or not the following character would +otherwise be interpreted as a metacharacter, so it is always safe to precede a +non-alphanumeric with backslash to specify that it stands for itself. In +particular, if you want to match a backslash, you write \\. +</P> +<P> +If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the +pattern (other than in a character class) and characters between a # outside +a character class and the next newline are ignored. An escaping backslash can +be used to include a whitespace or # character as part of the pattern. +</P> +<P> +If you want to remove the special meaning from a sequence of characters, you +can do so by putting them between \Q and \E. This is different from Perl in +that $ and @ are handled as literals in \Q...\E sequences in PCRE, whereas in +Perl, $ and @ cause variable interpolation. Note the following examples: +<pre> + Pattern PCRE matches Perl matches + + \Qabc$xyz\E abc$xyz abc followed by the contents of $xyz + \Qabc\$xyz\E abc\$xyz abc\$xyz + \Qabc\E\$\Qxyz\E abc$xyz abc$xyz +</pre> +The \Q...\E sequence is recognized both inside and outside character classes. +<a name="digitsafterbackslash"></a></P> +<br><b> +Non-printing characters +</b><br> +<P> +A second use of backslash provides a way of encoding non-printing characters +in patterns in a visible manner. There is no restriction on the appearance of +non-printing characters, apart from the binary zero that terminates a pattern, +but when a pattern is being prepared by text editing, it is usually easier to +use one of the following escape sequences than the binary character it +represents: +<pre> + \a alarm, that is, the BEL character (hex 07) + \cx "control-x", where x is any character + \e escape (hex 1B) + \f formfeed (hex 0C) + \n newline (hex 0A) + \r carriage return (hex 0D) + \t tab (hex 09) + \ddd character with octal code ddd, or backreference + \xhh character with hex code hh + \x{hhh..} character with hex code hhh.. +</pre> +The precise effect of \cx is as follows: if x is a lower case letter, it +is converted to upper case. Then bit 6 of the character (hex 40) is inverted. +Thus \cz becomes hex 1A, but \c{ becomes hex 3B, while \c; becomes hex +7B. +</P> +<P> +After \x, from zero to two hexadecimal digits are read (letters can be in +upper or lower case). Any number of hexadecimal digits may appear between \x{ +and }, but the value of the character code must be less than 256 in non-UTF-8 +mode, and less than 2**31 in UTF-8 mode (that is, the maximum hexadecimal value +is 7FFFFFFF). If characters other than hexadecimal digits appear between \x{ +and }, or if there is no terminating }, this form of escape is not recognized. +Instead, the initial \x will be interpreted as a basic hexadecimal escape, +with no following digits, giving a character whose value is zero. +</P> +<P> +Characters whose value is less than 256 can be defined by either of the two +syntaxes for \x. There is no difference in the way they are handled. For +example, \xdc is exactly the same as \x{dc}. +</P> +<P> +After \0 up to two further octal digits are read. If there are fewer than two +digits, just those that are present are used. Thus the sequence \0\x\07 +specifies two binary zeros followed by a BEL character (code value 7). Make +sure you supply two digits after the initial zero if the pattern character that +follows is itself an octal digit. +</P> +<P> +The handling of a backslash followed by a digit other than 0 is complicated. +Outside a character class, PCRE reads it and any following digits as a decimal +number. If the number is less than 10, or if there have been at least that many +previous capturing left parentheses in the expression, the entire sequence is +taken as a <i>back reference</i>. A description of how this works is given +<a href="#backreferences">later,</a> +following the discussion of +<a href="#subpattern">parenthesized subpatterns.</a> +</P> +<P> +Inside a character class, or if the decimal number is greater than 9 and there +have not been that many capturing subpatterns, PCRE re-reads up to three octal +digits following the backslash, ane uses them to generate a data character. Any +subsequent digits stand for themselves. In non-UTF-8 mode, the value of a +character specified in octal must be less than \400. In UTF-8 mode, values up +to \777 are permitted. For example: +<pre> + \040 is another way of writing a space + \40 is the same, provided there are fewer than 40 previous capturing subpatterns + \7 is always a back reference + \11 might be a back reference, or another way of writing a tab + \011 is always a tab + \0113 is a tab followed by the character "3" + \113 might be a back reference, otherwise the character with octal code 113 + \377 might be a back reference, otherwise the byte consisting entirely of 1 bits + \81 is either a back reference, or a binary zero followed by the two characters "8" and "1" +</pre> +Note that octal values of 100 or greater must not be introduced by a leading +zero, because no more than three octal digits are ever read. +</P> +<P> +All the sequences that define a single character value can be used both inside +and outside character classes. In addition, inside a character class, the +sequence \b is interpreted as the backspace character (hex 08), and the +sequence \X is interpreted as the character "X". Outside a character class, +these sequences have different meanings +<a href="#uniextseq">(see below).</a> +</P> +<br><b> +Generic character types +</b><br> +<P> +The third use of backslash is for specifying generic character types. The +following are always recognized: +<pre> + \d any decimal digit + \D any character that is not a decimal digit + \s any whitespace character + \S any character that is not a whitespace character + \w any "word" character + \W any "non-word" character +</pre> +Each pair of escape sequences partitions the complete set of characters into +two disjoint sets. Any given character matches one, and only one, of each pair. +</P> +<P> +These character type sequences can appear both inside and outside character +classes. They each match one character of the appropriate type. If the current +matching point is at the end of the subject string, all of them fail, since +there is no character to match. +</P> +<P> +For compatibility with Perl, \s does not match the VT character (code 11). +This makes it different from the the POSIX "space" class. The \s characters +are HT (9), LF (10), FF (12), CR (13), and space (32). (If "use locale;" is +included in a Perl script, \s may match the VT character. In PCRE, it never +does.) +</P> +<P> +A "word" character is an underscore or any character less than 256 that is a +letter or digit. The definition of letters and digits is controlled by PCRE's +low-valued character tables, and may vary if locale-specific matching is taking +place (see +<a href="pcreapi.html#localesupport">"Locale support"</a> +in the +<a href="pcreapi.html"><b>pcreapi</b></a> +page). For example, in the "fr_FR" (French) locale, some character codes +greater than 128 are used for accented letters, and these are matched by \w. +</P> +<P> +In UTF-8 mode, characters with values greater than 128 never match \d, \s, or +\w, and always match \D, \S, and \W. This is true even when Unicode +character property support is available. The use of locales with Unicode is +discouraged. +<a name="uniextseq"></a></P> +<br><b> +Unicode character properties +</b><br> +<P> +When PCRE is built with Unicode character property support, three additional +escape sequences to match character properties are available when UTF-8 mode +is selected. They are: +<pre> + \p{<i>xx</i>} a character with the <i>xx</i> property + \P{<i>xx</i>} a character without the <i>xx</i> property + \X an extended Unicode sequence +</pre> +The property names represented by <i>xx</i> above are limited to the Unicode +script names, the general category properties, and "Any", which matches any +character (including newline). Other properties such as "InMusicalSymbols" are +not currently supported by PCRE. Note that \P{Any} does not match any +characters, so always causes a match failure. +</P> +<P> +Sets of Unicode characters are defined as belonging to certain scripts. A +character from one of these sets can be matched using a script name. For +example: +<pre> + \p{Greek} + \P{Han} +</pre> +Those that are not part of an identified script are lumped together as +"Common". The current list of scripts is: +</P> +<P> +Arabic, +Armenian, +Bengali, +Bopomofo, +Braille, +Buginese, +Buhid, +Canadian_Aboriginal, +Cherokee, +Common, +Coptic, +Cypriot, +Cyrillic, +Deseret, +Devanagari, +Ethiopic, +Georgian, +Glagolitic, +Gothic, +Greek, +Gujarati, +Gurmukhi, +Han, +Hangul, +Hanunoo, +Hebrew, +Hiragana, +Inherited, +Kannada, +Katakana, +Kharoshthi, +Khmer, +Lao, +Latin, +Limbu, +Linear_B, +Malayalam, +Mongolian, +Myanmar, +New_Tai_Lue, +Ogham, +Old_Italic, +Old_Persian, +Oriya, +Osmanya, +Runic, +Shavian, +Sinhala, +Syloti_Nagri, +Syriac, +Tagalog, +Tagbanwa, +Tai_Le, +Tamil, +Telugu, +Thaana, +Thai, +Tibetan, +Tifinagh, +Ugaritic, +Yi. +</P> +<P> +Each character has exactly one general category property, specified by a +two-letter abbreviation. For compatibility with Perl, negation can be specified +by including a circumflex between the opening brace and the property name. For +example, \p{^Lu} is the same as \P{Lu}. +</P> +<P> +If only one letter is specified with \p or \P, it includes all the general +category properties that start with that letter. In this case, in the absence +of negation, the curly brackets in the escape sequence are optional; these two +examples have the same effect: +<pre> + \p{L} + \pL +</pre> +The following general category property codes are supported: +<pre> + C Other + Cc Control + Cf Format + Cn Unassigned + Co Private use + Cs Surrogate + + L Letter + Ll Lower case letter + Lm Modifier letter + Lo Other letter + Lt Title case letter + Lu Upper case letter + + M Mark + Mc Spacing mark + Me Enclosing mark + Mn Non-spacing mark + + N Number + Nd Decimal number + Nl Letter number + No Other number + + P Punctuation + Pc Connector punctuation + Pd Dash punctuation + Pe Close punctuation + Pf Final punctuation + Pi Initial punctuation + Po Other punctuation + Ps Open punctuation + + S Symbol + Sc Currency symbol + Sk Modifier symbol + Sm Mathematical symbol + So Other symbol + + Z Separator + Zl Line separator + Zp Paragraph separator + Zs Space separator +</pre> +The special property L& is also supported: it matches a character that has +the Lu, Ll, or Lt property, in other words, a letter that is not classified as +a modifier or "other". +</P> +<P> +The long synonyms for these properties that Perl supports (such as \p{Letter}) +are not supported by PCRE, nor is it permitted to prefix any of these +properties with "Is". +</P> +<P> +No character that is in the Unicode table has the Cn (unassigned) property. +Instead, this property is assumed for any code point that is not in the +Unicode table. +</P> +<P> +Specifying caseless matching does not affect these escape sequences. For +example, \p{Lu} always matches only upper case letters. +</P> +<P> +The \X escape matches any number of Unicode characters that form an extended +Unicode sequence. \X is equivalent to +<pre> + (?>\PM\pM*) +</pre> +That is, it matches a character without the "mark" property, followed by zero +or more characters with the "mark" property, and treats the sequence as an +atomic group +<a href="#atomicgroup">(see below).</a> +Characters with the "mark" property are typically accents that affect the +preceding character. +</P> +<P> +Matching characters by Unicode property is not fast, because PCRE has to search +a structure that contains data for over fifteen thousand characters. That is +why the traditional escape sequences such as \d and \w do not use Unicode +properties in PCRE. +<a name="smallassertions"></a></P> +<br><b> +Simple assertions +</b><br> +<P> +The fourth use of backslash is for certain simple assertions. An assertion +specifies a condition that has to be met at a particular point in a match, +without consuming any characters from the subject string. The use of +subpatterns for more complicated assertions is described +<a href="#bigassertions">below.</a> +The backslashed assertions are: +<pre> + \b matches at a word boundary + \B matches when not at a word boundary + \A matches at start of subject + \Z matches at end of subject or before newline at end + \z matches at end of subject + \G matches at first matching position in subject +</pre> +These assertions may not appear in character classes (but note that \b has a +different meaning, namely the backspace character, inside a character class). +</P> +<P> +A word boundary is a position in the subject string where the current character +and the previous character do not both match \w or \W (i.e. one matches +\w and the other matches \W), or the start or end of the string if the +first or last character matches \w, respectively. +</P> +<P> +The \A, \Z, and \z assertions differ from the traditional circumflex and +dollar (described in the next section) in that they only ever match at the very +start and end of the subject string, whatever options are set. Thus, they are +independent of multiline mode. These three assertions are not affected by the +PCRE_NOTBOL or PCRE_NOTEOL options, which affect only the behaviour of the +circumflex and dollar metacharacters. However, if the <i>startoffset</i> +argument of <b>pcre_exec()</b> is non-zero, indicating that matching is to start +at a point other than the beginning of the subject, \A can never match. The +difference between \Z and \z is that \Z matches before a newline at the end +of the string as well as at the very end, whereas \z matches only at the end. +</P> +<P> +The \G assertion is true only when the current matching position is at the +start point of the match, as specified by the <i>startoffset</i> argument of +<b>pcre_exec()</b>. It differs from \A when the value of <i>startoffset</i> is +non-zero. By calling <b>pcre_exec()</b> multiple times with appropriate +arguments, you can mimic Perl's /g option, and it is in this kind of +implementation where \G can be useful. +</P> +<P> +Note, however, that PCRE's interpretation of \G, as the start of the current +match, is subtly different from Perl's, which defines it as the end of the +previous match. In Perl, these can be different when the previously matched +string was empty. Because PCRE does just one match at a time, it cannot +reproduce this behaviour. +</P> +<P> +If all the alternatives of a pattern begin with \G, the expression is anchored +to the starting match position, and the "anchored" flag is set in the compiled +regular expression. +</P> +<br><a name="SEC3" href="#TOC1">CIRCUMFLEX AND DOLLAR</a><br> +<P> +Outside a character class, in the default matching mode, the circumflex +character is an assertion that is true only if the current matching point is +at the start of the subject string. If the <i>startoffset</i> argument of +<b>pcre_exec()</b> is non-zero, circumflex can never match if the PCRE_MULTILINE +option is unset. Inside a character class, circumflex has an entirely different +meaning +<a href="#characterclass">(see below).</a> +</P> +<P> +Circumflex need not be the first character of the pattern if a number of +alternatives are involved, but it should be the first thing in each alternative +in which it appears if the pattern is ever to match that branch. If all +possible alternatives start with a circumflex, that is, if the pattern is +constrained to match only at the start of the subject, it is said to be an +"anchored" pattern. (There are also other constructs that can cause a pattern +to be anchored.) +</P> +<P> +A dollar character is an assertion that is true only if the current matching +point is at the end of the subject string, or immediately before a newline +at the end of the string (by default). Dollar need not be the last character of +the pattern if a number of alternatives are involved, but it should be the last +item in any branch in which it appears. Dollar has no special meaning in a +character class. +</P> +<P> +The meaning of dollar can be changed so that it matches only at the very end of +the string, by setting the PCRE_DOLLAR_ENDONLY option at compile time. This +does not affect the \Z assertion. +</P> +<P> +The meanings of the circumflex and dollar characters are changed if the +PCRE_MULTILINE option is set. When this is the case, a circumflex matches +immediately after internal newlines as well as at the start of the subject +string. It does not match after a newline that ends the string. A dollar +matches before any newlines in the string, as well as at the very end, when +PCRE_MULTILINE is set. When newline is specified as the two-character +sequence CRLF, isolated CR and LF characters do not indicate newlines. +</P> +<P> +For example, the pattern /^abc$/ matches the subject string "def\nabc" (where +\n represents a newline) in multiline mode, but not otherwise. Consequently, +patterns that are anchored in single line mode because all branches start with +^ are not anchored in multiline mode, and a match for circumflex is possible +when the <i>startoffset</i> argument of <b>pcre_exec()</b> is non-zero. The +PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is set. +</P> +<P> +Note that the sequences \A, \Z, and \z can be used to match the start and +end of the subject in both modes, and if all branches of a pattern start with +\A it is always anchored, whether or not PCRE_MULTILINE is set. +</P> +<br><a name="SEC4" href="#TOC1">FULL STOP (PERIOD, DOT)</a><br> +<P> +Outside a character class, a dot in the pattern matches any one character in +the subject string except (by default) a character that signifies the end of a +line. In UTF-8 mode, the matched character may be more than one byte long. When +a line ending is defined as a single character (CR or LF), dot never matches +that character; when the two-character sequence CRLF is used, dot does not +match CR if it is immediately followed by LF, but otherwise it matches all +characters (including isolated CRs and LFs). +</P> +<P> +The behaviour of dot with regard to newlines can be changed. If the PCRE_DOTALL +option is set, a dot matches any one character, without exception. If newline +is defined as the two-character sequence CRLF, it takes two dots to match it. +</P> +<P> +The handling of dot is entirely independent of the handling of circumflex and +dollar, the only relationship being that they both involve newlines. Dot has no +special meaning in a character class. +</P> +<br><a name="SEC5" href="#TOC1">MATCHING A SINGLE BYTE</a><br> +<P> +Outside a character class, the escape sequence \C matches any one byte, both +in and out of UTF-8 mode. Unlike a dot, it always matches CR and LF. The +feature is provided in Perl in order to match individual bytes in UTF-8 mode. +Because it breaks up UTF-8 characters into individual bytes, what remains in +the string may be a malformed UTF-8 string. For this reason, the \C escape +sequence is best avoided. +</P> +<P> +PCRE does not allow \C to appear in lookbehind assertions +<a href="#lookbehind">(described below),</a> +because in UTF-8 mode this would make it impossible to calculate the length of +the lookbehind. +<a name="characterclass"></a></P> +<br><a name="SEC6" href="#TOC1">SQUARE BRACKETS AND CHARACTER CLASSES</a><br> +<P> +An opening square bracket introduces a character class, terminated by a closing +square bracket. A closing square bracket on its own is not special. If a +closing square bracket is required as a member of the class, it should be the +first data character in the class (after an initial circumflex, if present) or +escaped with a backslash. +</P> +<P> +A character class matches a single character in the subject. In UTF-8 mode, the +character may occupy more than one byte. A matched character must be in the set +of characters defined by the class, unless the first character in the class +definition is a circumflex, in which case the subject character must not be in +the set defined by the class. If a circumflex is actually required as a member +of the class, ensure it is not the first character, or escape it with a +backslash. +</P> +<P> +For example, the character class [aeiou] matches any lower case vowel, while +[^aeiou] matches any character that is not a lower case vowel. Note that a +circumflex is just a convenient notation for specifying the characters that +are in the class by enumerating those that are not. A class that starts with a +circumflex is not an assertion: it still consumes a character from the subject +string, and therefore it fails if the current pointer is at the end of the +string. +</P> +<P> +In UTF-8 mode, characters with values greater than 255 can be included in a +class as a literal string of bytes, or by using the \x{ escaping mechanism. +</P> +<P> +When caseless matching is set, any letters in a class represent both their +upper case and lower case versions, so for example, a caseless [aeiou] matches +"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a +caseful version would. In UTF-8 mode, PCRE always understands the concept of +case for characters whose values are less than 128, so caseless matching is +always possible. For characters with higher values, the concept of case is +supported if PCRE is compiled with Unicode property support, but not otherwise. +If you want to use caseless matching for characters 128 and above, you must +ensure that PCRE is compiled with Unicode property support as well as with +UTF-8 support. +</P> +<P> +Characters that might indicate line breaks (CR and LF) are never treated in any +special way when matching character classes, whatever line-ending sequence is +in use, and whatever setting of the PCRE_DOTALL and PCRE_MULTILINE options is +used. A class such as [^a] always matches one of these characters. +</P> +<P> +The minus (hyphen) character can be used to specify a range of characters in a +character class. For example, [d-m] matches any letter between d and m, +inclusive. If a minus character is required in a class, it must be escaped with +a backslash or appear in a position where it cannot be interpreted as +indicating a range, typically as the first or last character in the class. +</P> +<P> +It is not possible to have the literal character "]" as the end character of a +range. A pattern such as [W-]46] is interpreted as a class of two characters +("W" and "-") followed by a literal string "46]", so it would match "W46]" or +"-46]". However, if the "]" is escaped with a backslash it is interpreted as +the end of range, so [W-\]46] is interpreted as a class containing a range +followed by two other characters.

The supported class names +are +<pre> + alnum letters and digits + alpha letters + ascii character codes 0 - 127 + blank space or tab only + cntrl control characters + digit decimal digits (same as \d) + graph printing characters, excluding space + lower lower case letters + print printing characters, including space + punct printing characters, excluding letters and digits + space white space (not quite the same as \s) + upper upper case letters + word "word" characters (same as \w) + xdigit hexadecimal digits +</pre> +The "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13), and +space (32). Notice that this list includes the VT character (code 11). This +makes "space" different to \s, which does not include VT (for Perl +compatibility). +</P> +<P> +The name "word" is a Perl extension, and "blank" is a GNU extension from Perl +5.8. Another Perl extension is negation, which is indicated by a ^ character +after the colon. For example, +<pre> + [12[:^digit:]] +</pre> +matches "1", "2", or any non-digit. PCRE (and Perl) also recognize the POSIX +syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not +supported, and an error is given if they are encountered. +</P> +<P> +In UTF-8 mode, characters with values greater than 128 do not match any of +the POSIX character classes. +</P> +<br><a name="SEC8" href="#TOC1">VERTICAL BAR</a><br> +<P> +Vertical bar characters are used to separate alternative patterns. For example, +the pattern +<pre> + gilbert|sullivan +</pre> +matches either "gilbert" or "sullivan". Any number of alternatives may appear, +and an empty alternative is permitted (matching the empty string). The matching +process tries each alternative in turn, from left to right, and the first one +that succeeds is used. If the alternatives are within a subpattern +<a href="#subpattern">(defined below),</a> +"succeeds" means matching the rest of the main pattern as well as the +alternative in the subpattern. +</P> +<br><a name="SEC9" href="#TOC1">INTERNAL OPTION SETTING</a><br> +<P> +The settings of the PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and +PCRE_EXTENDED options can be changed from within the pattern by a sequence of +Perl option letters enclosed between "(?" and ")". The option letters are +<pre> + i for PCRE_CASELESS + m for PCRE_MULTILINE + s for PCRE_DOTALL + x for PCRE_EXTENDED +</pre> +For example, (?im) sets caseless, multiline matching. It is also possible to +unset these options by preceding the letter with a hyphen, and a combined +setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and +PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also +permitted. If a letter appears both before and after the hyphen, the option is +unset. +</P> +<P> +When an option change occurs at top level (that is, not inside subpattern +parentheses), the change applies to the remainder of the pattern that follows. +If the change is placed right at the start of a pattern, PCRE extracts it into +the global options (and it will therefore show up in data extracted by the +<b>pcre_fullinfo()</b> function). +</P> +<P> +An option change within a subpattern affects only that part of the current +pattern that follows it, so +<pre> + (a(?i)b)c +</pre> +matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used). +By this means, options can be made to have different settings in different +parts of the pattern. Any changes made in one alternative do carry on +into subsequent branches within the same subpattern. For example, +<pre> + (a(?i)b|c) +</pre> +matches "ab", "aB", "c", and "C", even though when matching "C" the first +branch is abandoned before the option setting. This is because the effects of +option settings happen at compile time. There would be some very weird +behaviour otherwise. +</P> +<P> +The PCRE-specific options PCRE_DUPNAMES, PCRE_UNGREEDY, and PCRE_EXTRA can be +changed in the same way as the Perl-compatible options by using the characters +J, U and X respectively. +<a name="subpattern"></a></P> +<br><a name="SEC10" href="#TOC1">SUBPATTERNS</a><br> +<P> +Subpatterns are delimited by parentheses (round brackets), which can be nested. +Turning part of a pattern into a subpattern does two things: +<br> +<br> +1. It localizes a set of alternatives. For example, the pattern +<pre> + cat(aract|erpillar|) +</pre> +matches one of the words "cat", "cataract", or "caterpillar". Without the +parentheses, it would match "cataract", "erpillar" or the empty string. +<br> +<br> +2. It sets up the subpattern as a capturing subpattern. This means that, when +the whole pattern matches, that portion of the subject string that matched the +subpattern is passed back to the caller via the <i>ovector</i> argument of +<b>pcre_exec()</b>. Opening parentheses are counted from left to right (starting +from 1) to obtain numbers for the capturing subpatterns. +</P> +<P> +For example, if the string "the red king" is matched against the pattern +<pre> + the ((red|white) (king|queen)) +</pre> +the captured substrings are "red king", "red", and "king", and are numbered 1, +2, and 3, respectively. +</P> +<P> +The fact that plain parentheses fulfil two functions is not always helpful. +There are often times when a grouping subpattern is required without a +capturing requirement. If an opening parenthesis is followed by a question mark +and a colon, the subpattern does not do any capturing, and is not counted when +computing the number of any subsequent capturing subpatterns. For example, if +the string "the white queen" is matched against the pattern +<pre> + the ((?:red|white) (king|queen)) +</pre> +the captured substrings are "white queen" and "queen", and are numbered 1 and +2. The maximum number of capturing subpatterns is 65535, and the maximum depth +of nesting of all subpatterns, both capturing and non-capturing, is 200. +</P> +<P> +As a convenient shorthand, if any option settings are required at the start of +a non-capturing subpattern, the option letters may appear between the "?" and +the ":". Thus the two patterns +<pre> + (?i:saturday|sunday) + (?:(?i)saturday|sunday) +</pre> +match exactly the same set of strings. Because alternative branches are tried +from left to right, and options are not reset until the end of the subpattern +is reached, an option setting in one branch does affect subsequent branches, so +the above patterns match "SUNDAY" as well as "Saturday". +</P> +<br><a name="SEC11" href="#TOC1">NAMED SUBPATTERNS</a><br> +<P> +Identifying capturing parentheses by number is simple, but it can be very hard +to keep track of the numbers in complicated regular expressions. Furthermore, +if an expression is modified, the numbers may change. To help with this +difficulty, PCRE supports the naming of subpatterns, something that Perl does +not provide. The Python syntax (?P<name>...) is used. References to capturing +parentheses from other parts of the pattern, such as +<a href="#backreferences">backreferences,</a> +<a href="#recursion">recursion,</a> +and +<a href="#conditions">conditions,</a> +can be made by name as well as by number. +</P> +<P> +Names consist of up to 32 alphanumeric characters and underscores. Named +capturing parentheses are still allocated numbers as well as names. The PCRE +API provides function calls for extracting the name-to-number translation table +from a compiled pattern. There is also a convenience function for extracting a +captured substring by name. +</P> +<P> +By default, a name must be unique within a pattern, but it is possible to relax +this constraint by setting the PCRE_DUPNAMES option at compile time. This can +be useful for patterns where only one instance of the named parentheses can +match. Suppose you want to match the name of a weekday, either as a 3-letter +abbreviation or as the full name, and in both cases you want to extract the +abbreviation. This pattern (ignoring the line breaks) does the job: +<pre> + (?P<DN>Mon|Fri|Sun)(?:day)?| + (?P<DN>Tue)(?:sday)?| + (?P<DN>Wed)(?:nesday)?| + (?P<DN>Thu)(?:rsday)?| + (?P<DN>Sat)(?:urday)? +</pre> +There are five capturing substrings, but only one is ever set after a match. +The convenience function for extracting the data by name returns the substring +for the first, and in this example, the only, subpattern of that name that +matched. This saves searching to find which numbered subpattern it was. If you +make a reference to a non-unique named subpattern from elsewhere in the +pattern, the one that corresponds to the lowest number is used. For further +details of the interfaces for handling named subpatterns, see the +<a href="pcreapi.html"><b>pcreapi</b></a> +documentation. +</P> +<br><a name="SEC12" href="#TOC1">REPETITION</a><br> +<P> +Repetition is specified by quantifiers, which can follow any of the following +items: +<pre> + a literal data character + the . metacharacter + the \C escape sequence + the \X escape sequence (in UTF-8 mode with Unicode properties) + an escape such as \d that matches a single character + a character class + a back reference (see next section) + a parenthesized subpattern (unless it is an assertion) +</pre> +The general repetition quantifier specifies a minimum and maximum number of +permitted matches, by giving the two numbers in curly brackets (braces), +separated by a comma. The numbers must be less than 65536, and the first must +be less than or equal to the second. For example: +<pre> + z{2,4} +</pre> +matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special +character. If the second number is omitted, but the comma is present, there is +no upper limit; if the second number and the comma are both omitted, the +quantifier specifies an exact number of required matches. Thus +<pre> + [aeiou]{3,} +</pre> +matches at least 3 successive vowels, but may match many more, while +<pre> + \d{8} +</pre> +matches exactly 8 digits. An opening curly bracket that appears in a position +where a quantifier is not allowed, or one that does not match the syntax of a +quantifier, is taken as a literal character. For example, {,6} is not a +quantifier, but a literal string of four characters. +</P> +<P> +In UTF-8 mode, quantifiers apply to UTF-8 characters rather than to individual +bytes. Thus, for example, \x{100}{2} matches two UTF-8 characters, each of +which is represented by a two-byte sequence. Similarly, when Unicode property +support is available, \X{3} matches three Unicode extended sequences, each of +which may be several bytes long (and they may be of different lengths). +</P> +<P> +The quantifier {0} is permitted, causing the expression to behave as if the +previous item and the quantifier were not present. +</P> +<P> +For convenience (and historical compatibility) the three most common +quantifiers have single-character abbreviations: +<pre> + * is equivalent to {0,} + + is equivalent to {1,} + ? is equivalent to {0,1} +</pre> +It is possible to construct infinite loops by following a subpattern that can +match no characters with a quantifier that has no upper limit, for example: +<pre> + (a?)* +</pre> +Earlier versions of Perl and PCRE used to give an error at compile time for +such patterns. However, because there are cases where this can be useful, such +patterns are now accepted, but if any repetition of the subpattern does in fact +match no characters, the loop is forcibly broken. +</P> +<P> +By default, the quantifiers are "greedy", that is, they match as much as +possible (up to the maximum number of permitted times), without causing the +rest of the pattern to fail. The classic example of where this gives problems +is in trying to match comments in C programs. These appear between /* and */ +and within the comment, individual * and / characters may appear. An attempt to +match C comments by applying the pattern +<pre> + /\*.*\*/ +</pre> +to the string +<pre> + /* first comment */ not comment /* second comment */ +</pre> +fails, because it matches the entire string owing to the greediness of the .* +item. +</P> +<P> +However, if a quantifier is followed by a question mark, it ceases to be +greedy, and instead matches the minimum number of times possible, so the +pattern +<pre> + /\*.*?\*/ +</pre> +does the right thing with the C comments. The meaning of the various +quantifiers is not otherwise changed, just the preferred number of matches. +Do not confuse this use of question mark with its use as a quantifier in its +own right. Because it has two uses, it can sometimes appear doubled, as in +<pre> + \d??\d +</pre> +which matches one digit by preference, but can match two if that is the only +way the rest of the pattern matches. +</P> +<P> +If the PCRE_UNGREEDY option is set (an option which is not available in Perl), +the quantifiers are not greedy by default, but individual ones can be made +greedy by following them with a question mark. In other words, it inverts the +default behaviour. +</P> +<P> +When a parenthesized subpattern is quantified with a minimum repeat count that +is greater than 1 or with a limited maximum, more memory is required for the +compiled pattern, in proportion to the size of the minimum or maximum. +</P> +<P> +If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent +to Perl's /s) is set, thus allowing the . to match newlines, the pattern is +implicitly anchored, because whatever follows will be tried against every +character position in the subject string, so there is no point in retrying the +overall match at any position after the first. PCRE normally treats such a +pattern as though it were preceded by \A. +</P> +<P> +In cases where it is known that the subject string contains no newlines, it is +worth setting PCRE_DOTALL in order to obtain this optimization, or +alternatively using ^ to indicate anchoring explicitly. +</P> +<P> +However, there is one situation where the optimization cannot be used. When .* +is inside capturing parentheses that are the subject of a backreference +elsewhere in the pattern, a match at the start may fail, and a later one +succeed. Consider, for example: +<pre> + (.*)abc\1 +</pre> +If the subject is "xyz123abc123" the match point is the fourth character. For +this reason, such a pattern is not implicitly anchored. +</P> +<P> +When a capturing subpattern is repeated, the value captured is the substring +that matched the final iteration. For example, after +<pre> + (tweedle[dume]{3}\s*)+ +</pre> +has matched "tweedledum tweedledee" the value of the captured substring is +"tweedledee". However, if there are nested capturing subpatterns, the +corresponding captured values may have been set in previous iterations. For +example, after +<pre> + /(a|(b))+/ +</pre> +matches "aba" the value of the second captured substring is "b". +<a name="atomicgroup"></a></P> +<br><a name="SEC13" href="#TOC1">ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS</a><br> +<P> +With both maximizing and minimizing repetition, failure of what follows +normally causes the repeated item to be re-evaluated to see if a different +number of repeats allows the rest of the pattern to match. Sometimes it is +useful to prevent this, either to change the nature of the match, or to cause +it fail earlier than it otherwise might, when the author of the pattern knows +there is no point in carrying on. +</P> +<P> +Consider, for example, the pattern \d+foo when applied to the subject line +<pre> + 123456bar +</pre> +After matching all 6 digits and then failing to match "foo", the normal +action of the matcher is to try again with only 5 digits matching the \d+ +item, and then with 4, and so on, before ultimately failing. "Atomic grouping" +(a term taken from Jeffrey Friedl's book) provides the means for specifying +that once a subpattern has matched, it is not to be re-evaluated in this way. +</P> +<P> +If we use atomic grouping for the previous example, the matcher would give up +immediately on failing to match "foo" the first time. The notation is a kind of +special parenthesis, starting with (?> as in this example: +<pre> + (?>\d+)foo +</pre> +This kind of parenthesis "locks up" the part of the pattern it contains once +it has matched, and a failure further into the pattern is prevented from +backtracking into it. Backtracking past it to previous items, however, works as +normal. +</P> +<P> +An alternative description is that a subpattern of this type matches the string +of characters that an identical standalone pattern would match, if anchored at +the current point in the subject string. +</P> +<P> +Atomic grouping subpatterns are not capturing subpatterns. Simple cases such as +the above example can be thought of as a maximizing repeat that must swallow +everything it can. So, while both \d+ and \d+? are prepared to adjust the +number of digits they match in order to make the rest of the pattern match, +(?>\d+) can only match an entire sequence of digits. +</P> +<P> +Atomic groups in general can of course contain arbitrarily complicated +subpatterns, and can be nested. However, when the subpattern for an atomic +group is just a single repeated item, as in the example above, a simpler +notation, called a "possessive quantifier" can be used. This consists of an +additional + character following a quantifier. Using this notation, the +previous example can be rewritten as +<pre> + \d++foo +</pre> +Possessive quantifiers are always greedy; the setting of the PCRE_UNGREEDY +option is ignored. They are a convenient notation for the simpler forms of +atomic group. However, there is no difference in the meaning or processing of a +possessive quantifier and the equivalent atomic group. +</P> +<P> +The possessive quantifier syntax is an extension to the Perl syntax. Jeffrey +Friedl originated the idea (and the name) in the first edition of his book. +Mike McCloskey liked it, so implemented it when he built Sun's Java package, +and PCRE copied it from there. +</P> +<P> +When a pattern contains an unlimited repeat inside a subpattern that can itself +be repeated an unlimited number of times, the use of an atomic group is the +only way to avoid some failing matches taking a very long time indeed. The +pattern +<pre> + (\D+|<\d+>)*[!?] +</pre> +matches an unlimited number of substrings that either consist of non-digits, or +digits enclosed in <>, followed by either ! or ?. When it matches, it runs +quickly. However, if it is applied to +<pre> + aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +</pre> +it takes a long time before reporting failure. This is because the string can +be divided between the internal \D+ repeat and the external * repeat in a +large number of ways, and all have to be tried. (The example uses [!?] rather +than a single character at the end, because both PCRE and Perl have an +optimization that allows for fast failure when a single character is used. They +remember the last single character that is required for a match, and fail early +if it is not present in the string.) If the pattern is changed so that it uses +an atomic group, like this: +<pre> + ((?>\D+)|<\d+>)*[!?] +</pre> +sequences of non-digits cannot be broken, and failure happens quickly. +<a name="backreferences"></a></P> +<br><a name="SEC14" href="#TOC1">BACK REFERENCES</a><br> +<P> +Outside a character class, a backslash followed by a digit greater than 0 (and +possibly further digits) is a back reference to a capturing subpattern earlier +(that is, to its left) in the pattern, provided there have been that many +previous capturing left parentheses. +</P> +<P> +However, if the decimal number following the backslash is less than 10, it is +always taken as a back reference, and causes an error only if there are not +that many capturing left parentheses in the entire pattern. In other words, the +parentheses that are referenced need not be to the left of the reference for +numbers less than 10. A "forward back reference" of this type can make sense +when a repetition is involved and the subpattern to the right has participated +in an earlier iteration. +</P> +<P> +It is not possible to have a numerical "forward back reference" to subpattern +whose number is 10 or more. However, a back reference to any subpattern is +possible using named parentheses (see below). See also the subsection entitled +"Non-printing characters" +<a href="#digitsafterbackslash">above</a> +for further details of the handling of digits following a backslash. +</P> +<P> +A back reference matches whatever actually matched the capturing subpattern in +the current subject string, rather than anything matching the subpattern +itself (see +<a href="#subpatternsassubroutines">"Subpatterns as subroutines"</a> +below for a way of doing that). So the pattern +<pre> + (sens|respons)e and \1ibility +</pre> +matches "sense and sensibility" and "response and responsibility", but not +"sense and responsibility". If caseful matching is in force at the time of the +back reference, the case of letters is relevant. For example, +<pre> + ((?i)rah)\s+\1 +</pre> +matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original +capturing subpattern is matched caselessly. +</P> +<P> +Back references to named subpatterns use the Python syntax (?P=name). We could +rewrite the above example as follows: +<pre> + (?P<p1>(?i)rah)\s+(?P=p1) +</pre> +A subpattern that is referenced by name may appear in the pattern before or +after the reference. +</P> +<P> +There may be more than one back reference to the same subpattern. If a +subpattern has not actually been used in a particular match, any back +references to it always fail. For example, the pattern +<pre> + (a|(bc))\2 +</pre> +always fails if it starts to match "a" rather than "bc". Because there may be +many capturing parentheses in a pattern, all digits following the backslash are +taken as part of a potential back reference number. If the pattern continues +with a digit character, some delimiter must be used to terminate the back +reference. If the PCRE_EXTENDED option is set, this can be whitespace. +Otherwise an empty comment (see +<a href="#comments">"Comments"</a> +below) can be used. +</P> +<P> +A back reference that occurs inside the parentheses to which it refers fails +when the subpattern is first used, so, for example, (a\1) never matches. +However, such references can be useful inside repeated subpatterns. For +example, the pattern +<pre> + (a|b\1)+ +</pre> +matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of +the subpattern, the back reference matches the character string corresponding +to the previous iteration. In order for this to work, the pattern must be such +that the first iteration does not need to match the back reference. This can be +done using alternation, as in the example above, or by a quantifier with a +minimum of zero. +<a name="bigassertions"></a></P> +<br><a name="SEC15" href="#TOC1">ASSERTIONS</a><br> +<P> +An assertion is a test on the characters following or preceding the current +matching point that does not actually consume any characters.

Consider a simple pattern +such as +<pre> + abcd$ +</pre> +when applied to a long string that does not match. Because matching proceeds +from left to right, PCRE will look for each "a" in the subject and then see if +what follows matches the rest of the pattern. If the pattern is specified as +<pre> + ^.*abcd$ +</pre> +the initial .* matches the entire string at first, but when this fails (because +there is no following "a"), it backtracks to match all but the last character, +then all but the last two characters, and so on.

However, +if the pattern is written as +<pre> + ^(?>.*)(?<=abcd) +</pre> +or, equivalently, using the possessive quantifier syntax, +<pre> + ^.*+(?<=abcd) +</pre> +there can be no backtracking for the .* item; it can match only the entire +string. The subsequent lookbehind assertion does a single test on the last four +characters. If it fails, the match fails immediately. For long strings, this +approach makes a significant difference to the processing time. +</P> +<br><b> +Using multiple assertions +</b><br> +<P> +Several assertions (of any sort) may occur in succession. For example, +<pre> + (?<=\d{3})(?<!999)foo +</pre> +matches "foo" preceded by three digits that are not "999". Notice that each of +the assertions is applied independently at the same point in the subject +string. First there is a check that the previous three characters are all +digits, and then there is a check that the same three characters are not "999". +This pattern does <i>not</i> match "foo" preceded by six characters, the first +of which are digits and the last three of which are not "999". For example, it +doesn't match "123abcfoo". A pattern to do that is +<pre> + (?<=\d{3}...)(?<!999)foo +</pre> +This time the first assertion looks at the preceding six characters, checking +that the first three are digits, and then the second assertion checks that the +preceding three characters are not "999". +</P> +<P> +Assertions can be nested in any combination. For example, +<pre> + (?<=(?<!foo)bar)baz +</pre> +matches an occurrence of "baz" that is preceded by "bar" which in turn is not +preceded by "foo", while +<pre> + (?<=\d{3}(?!999)...)foo +</pre> +is another pattern that matches "foo" preceded by three digits and any three +characters that are not "999". +<a name="conditions"></a></P> +<br><a name="SEC16" href="#TOC1">CONDITIONAL SUBPATTERNS</a><br> +<P> +It is possible to cause the matching process to obey a subpattern +conditionally or to choose between two alternative subpatterns, depending on +the result of an assertion, or whether a previous capturing subpattern matched +or not. The two possible forms of conditional subpattern are +<pre> + (?(condition)yes-pattern) + (?(condition)yes-pattern|no-pattern) +</pre> +If the condition is satisfied, the yes-pattern is used; otherwise the +no-pattern (if present) is used. If there are more than two alternatives in the +subpattern, a compile-time error occurs. +</P> +<P> +There are three kinds of condition. If the text between the parentheses +consists of a sequence of digits, or a sequence of alphanumeric characters and +underscores, the condition is satisfied if the capturing subpattern of that +number or name has previously matched. There is a possible ambiguity here, +because subpattern names may consist entirely of digits. PCRE looks first for a +named subpattern; if it cannot find one and the text consists entirely of +digits, it looks for a subpattern of that number, which must be greater than +zero. Using subpattern names that consist entirely of digits is not +recommended. +</P> +<P> +Consider the following pattern, which contains non-significant white space to +make it more readable (assume the PCRE_EXTENDED option) and to divide it into +three parts for ease of discussion: +<pre> + ( \( )? [^()]+ (?(1) \) ) +</pre> +The first part matches an optional opening parenthesis, and if that +character is present, sets it as the first captured substring. The second part +matches one or more characters that are not parentheses. The third part is a +conditional subpattern that tests whether the first set of parentheses matched +or not. If they did, that is, if subject started with an opening parenthesis, +the condition is true, and so the yes-pattern is executed and a closing +parenthesis is required. Otherwise, since no-pattern is not present, the +subpattern matches nothing. In other words, this pattern matches a sequence of +non-parentheses, optionally enclosed in parentheses. Rewriting it to use a +named subpattern gives this: +<pre> + (?P<OPEN> \( )? [^()]+ (?(OPEN) \) ) +</pre> +If the condition is the string (R), and there is no subpattern with the name R, +the condition is satisfied if a recursive call to the pattern or subpattern has +been made. At "top level", the condition is false. This is a PCRE extension. +Recursive patterns are described in the next section. +</P> +<P> +If the condition is not a sequence of digits or (R), it must be an assertion. +This may be a positive or negative lookahead or lookbehind assertion. Consider +this pattern, again containing non-significant white space, and with the two +alternatives on the second line: +<pre> + (?(?=[^a-z]*[a-z]) + \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} ) +</pre> +The condition is a positive lookahead assertion that matches an optional +sequence of non-letters followed by a letter. In other words, it tests for the +presence of at least one letter in the subject. If a letter is found, the +subject is matched against the first alternative; otherwise it is matched +against the second. This pattern matches strings in one of the two forms +dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits. +<a name="comments"></a></P> +<br><a name="SEC17" href="#TOC1">COMMENTS</a><br> +<P> +The sequence (?# marks the start of a comment that continues up to the next +closing parenthesis. Nested parentheses are not permitted. The characters +that make up a comment play no part in the pattern matching at all. +</P> +<P> +If the PCRE_EXTENDED option is set, an unescaped # character outside a +character class introduces a comment that continues to immediately after the +next newline in the pattern. +<a name="recursion"></a></P> +<br><a name="SEC18" href="#TOC1">RECURSIVE PATTERNS</a><br> +<P> +Consider the problem of matching a string in parentheses, allowing for +unlimited nested parentheses. Without the use of recursion, the best that can +be done is to use a pattern that matches up to some fixed depth of nesting. It +is not possible to handle an arbitrary nesting depth. Perl provides a facility +that allows regular expressions to recurse (amongst other things). It does this +by interpolating Perl code in the expression at run time, and the code can +refer to the expression itself. A Perl pattern to solve the parentheses problem +can be created like this: +<pre> + $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x; +</pre> +The (?p{...}) item interpolates Perl code at run time, and in this case refers +recursively to the pattern in which it appears. Obviously, PCRE cannot support +the interpolation of Perl code. Instead, it supports some special syntax for +recursion of the entire pattern, and also for individual subpattern recursion. +</P> +<P> +The special item that consists of (? followed by a number greater than zero and +a closing parenthesis is a recursive call of the subpattern of the given +number, provided that it occurs inside that subpattern. (If not, it is a +"subroutine" call, which is described in the next section.) The special item +(?R) is a recursive call of the entire regular expression. +</P> +<P> +A recursive subpattern call is always treated as an atomic group. That is, once +it has matched some of the subject string, it is never re-entered, even if +it contains untried alternatives and there is a subsequent matching failure. +</P> +<P> +This PCRE pattern solves the nested parentheses problem (assume the +PCRE_EXTENDED option is set so that white space is ignored): +<pre> + \( ( (?>[^()]+) | (?R) )* \) +</pre> +First it matches an opening parenthesis. Then it matches any number of +substrings which can either be a sequence of non-parentheses, or a recursive +match of the pattern itself (that is, a correctly parenthesized substring). +Finally there is a closing parenthesis. +</P> +<P> +If this were part of a larger pattern, you would not want to recurse the entire +pattern, so instead you could use this: +<pre> + ( \( ( (?>[^()]+) | (?1) )* \) ) +</pre> +We have put the pattern into parentheses, and caused the recursion to refer to +them instead of the whole pattern. In a larger pattern, keeping track of +parenthesis numbers can be tricky. It may be more convenient to use named +parentheses instead. For this, PCRE uses (?P>name), which is an extension to +the Python syntax that PCRE uses for named parentheses (Perl does not provide +named parentheses). We could rewrite the above example as follows: +<pre> + (?P<pn> \( ( (?>[^()]+) | (?P>pn) )* \) ) +</pre> +This particular example pattern contains nested unlimited repeats, and so the +use of atomic grouping for matching strings of non-parentheses is important +when applying the pattern to strings that do not match. For example, when this +pattern is applied to +<pre> + (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa() +</pre> +it yields "no match" quickly. However, if atomic grouping is not used, +the match runs for a very long time indeed because there are so many different +ways the + and * repeats can carve up the subject, and all have to be tested +before failure can be reported. +</P> +<P> +At the end of a match, the values set for any capturing subpatterns are those +from the outermost level of the recursion at which the subpattern value is set. +If you want to obtain intermediate values, a callout function can be used (see +the next section and the +<a href="pcrecallout.html"><b>pcrecallout</b></a> +documentation). If the pattern above is matched against +<pre> + (ab(cd)ef) +</pre> +the value for the capturing parentheses is "ef", which is the last value taken +on at the top level. If additional parentheses are added, giving +<pre> + \( ( ( (?>[^()]+) | (?R) )* ) \) + ^ ^ + ^ ^ +</pre> +the string they capture is "ab(cd)ef", the contents of the top level +parentheses. If there are more than 15 capturing parentheses in a pattern, PCRE +has to obtain extra memory to store data during a recursion, which it does by +using <b>pcre_malloc</b>, freeing it via <b>pcre_free</b> afterwards. If no +memory can be obtained, the match fails with the PCRE_ERROR_NOMEMORY error. +</P> +<P> +Do not confuse the (?R) item with the condition (R), which tests for recursion. +Consider this pattern, which matches text in angle brackets, allowing for +arbitrary nesting. Only digits are allowed in nested brackets (that is, when +recursing), whereas any characters are permitted at the outer level. +<pre> + < (?: (?(R) \d++ | [^<>]*+) | (?R)) * > +</pre> +In this pattern, (?(R) is the start of a conditional subpattern, with two +different alternatives for the recursive and non-recursive cases.

An earlier example pointed out that the +pattern +<pre> + (sens|respons)e and \1ibility +</pre> +matches "sense and sensibility" and "response and responsibility", but not +"sense and responsibility". If instead the pattern +<pre> + (sens|respons)e and (?1)ibility +</pre> +is used, it does match "sense and responsibility" as well as the other two +strings.

It is more efficient to use a character class like [aeiou] than a +set of alternatives such as (a|e|i|o|u). In general, the simplest construction +that provides the required behaviour is usually the most efficient. Jeffrey +Friedl's book contains a lot of useful general discussion about optimizing +regular expressions for efficient performance. This document contains a few +observations about PCRE. +</P> +<P> +Using Unicode character properties (the \p, \P, and \X escapes) is slow, +because PCRE has to scan a structure that contains data for over fifteen +thousand characters whenever it needs a character's property. If you can find +an alternative pattern that does not use character properties, it will probably +be faster. +</P> +<P> +When a pattern begins with .* not in parentheses, or in parentheses that are +not the subject of a backreference, and the PCRE_DOTALL option is set, the +pattern is implicitly anchored by PCRE, since it can match only at the start of +a subject string. However, if PCRE_DOTALL is not set, PCRE cannot make this +optimization, because the . metacharacter does not then match a newline, and if +the subject string contains newlines, the pattern may match from the character +immediately following one of them instead of from the very start. For example, +the pattern +<pre> + .*second +</pre> +matches the subject "first\nand second" (where \n stands for a newline +character), with the match starting at the seventh character. In order to do +this, PCRE has to retry the match starting after every newline in the subject. +</P> +<P> +If you are using such a pattern with subject strings that do not contain +newlines, the best performance is obtained by setting PCRE_DOTALL, or starting +the pattern with ^.* or ^.*? to indicate explicit anchoring. That saves PCRE +from having to scan along the subject looking for a newline to restart at. +</P> +<P> +Beware of patterns that contain nested indefinite repeats. These can take a +long time to run when applied to a string that does not match. Consider the +pattern fragment +<pre> + (a+)* +</pre> +This can match "aaaa" in 33 different ways, and this number increases very +rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4 +times, and for each of those cases other than 0, the + repeats can match +different numbers of times.) When the remainder of the pattern is such that the +entire match is going to fail, PCRE has in principle to try every possible +variation, and this can take an extremely long time. +</P> +<P> +An optimization catches some of the more simple cases such as +<pre> + (a+)*b +</pre> +where a literal character follows. Before embarking on the standard matching +procedure, PCRE checks that there is a "b" later in the subject string, and if +there is not, it fails the match immediately. However, when there is no +following literal this optimization cannot be used. You can see the difference +by comparing the behaviour of +<pre> + (a+)*\d +</pre> +with the pattern above. The former gives a failure almost instantly when +applied to a whole line of "a" characters, whereas the latter takes an +appreciable time with strings longer than about 20 characters. +</P> +<P> +In many cases, the solution to this kind of performance issue is to use an +atomic group or a possessive quantifier. +</P> +<P> +Last updated: 28 February 2005 +<br> +Copyright © 1997-2005 University of Cambridge. +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> Added: freeswitch/trunk/libs/pcre/doc/html/pcreposix.html ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/doc/html/pcreposix.html Tue Dec 19 14:54:26 2006 @@ -0,0 +1,244 @@ +<html> +<head> +<title>pcreposix specification</title> +</head> +<body bgcolor="#FFFFFF" text="#00005A" link="#0066FF" alink="#3399FF" vlink="#2222BB"> +<h1>pcreposix man page</h1> +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> +<p> +This page is part of the PCRE HTML documentation.

Their prototypes are defined in the <b>pcreposix.h</b> +header file, and on Unix systems the library itself is called +<b>pcreposix.a</b>, so can be accessed by adding <b>-lpcreposix</b> to the +command for linking an application that uses them. Because the POSIX functions +call the native ones, it is also necessary to add <b>-lpcre</b>. +</P> +<P> +I have implemented only those option bits that can be reasonably mapped to PCRE +native options. In addition, the option REG_EXTENDED is defined with the value +zero.

The syntax and semantics of the regular expressions themselves are +still those of Perl, subject to the setting of various PCRE options, as +described below. "POSIX-like in style" means that the API approximates to the +POSIX definition; it is not fully POSIX-compatible, and in multi-byte encoding +domains it is probably even less compatible. +</P> +<P> +The header for these functions is supplied as <b>pcreposix.h</b> to avoid any +potential clash with other POSIX libraries. It can, of course, be renamed or +aliased as <b>regex.h</b>, which is the "correct" name. It provides two +structure types, <i>regex_t</i> for compiled internal forms, and +<i>regmatch_t</i> for returning captured substrings. It also defines some +constants whose names start with "REG_"; these are used for setting options and +identifying error codes. +</P> +<P> +</P> +<br><a name="SEC3" href="#TOC1">COMPILING A PATTERN</a><br> +<P> +The function <b>regcomp()</b> is called to compile a pattern into an +internal form. The pattern is a C string terminated by a binary zero, and +is passed in the argument <i>pattern</i>. The <i>preg</i> argument is a pointer +to a <b>regex_t</b> structure that is used as a base for storing information +about the compiled regular expression. +</P> +<P> +The argument <i>cflags</i> is either zero, or contains one or more of the bits +defined by the following macros: +<pre> + REG_DOTALL +</pre> +The PCRE_DOTALL option is set when the regular expression is passed for +compilation to the native function.

Note that this does <i>not</i> mimic the +defined POSIX behaviour for REG_NEWLINE (see the following section). +<pre> + REG_NOSUB +</pre> +The PCRE_NO_AUTO_CAPTURE option is set when the regular expression is passed +for compilation to the native function. In addition, when a pattern that is +compiled with this flag is passed to <b>regexec()</b> for matching, the +<i>nmatch</i> and <i>pmatch</i> arguments are ignored, and no captured strings +are returned. +<pre> + REG_UTF8 +</pre> +The PCRE_UTF8 option is set when the regular expression is passed for +compilation to the native function. This causes the pattern itself and all data +strings used for matching it to be treated as UTF-8 strings. Note that REG_UTF8 +is not part of the POSIX standard. +</P> +<P> +In the absence of these flags, no options are passed to the native function. +This means the the regex is compiled with PCRE default semantics. In +particular, the way it handles newline characters in the subject string is the +Perl way, not the POSIX way. Note that setting PCRE_MULTILINE has only +<i>some</i> of the effects specified for REG_NEWLINE. It does not affect the way +newlines are matched by . (they aren't) or by a negative class such as [^a] +(they are). +</P> +<P> +The yield of <b>regcomp()</b> is zero on success, and non-zero otherwise.

In both PCRE and Perl, there is no way to stop +newline from matching [^a]. +</P> +<P> +The default POSIX newline handling can be obtained by setting PCRE_DOTALL and +PCRE_DOLLAR_ENDONLY, but there is no way to make PCRE behave exactly as for the +REG_NEWLINE action. +</P> +<br><a name="SEC5" href="#TOC1">MATCHING A PATTERN</a><br> +<P> +The function <b>regexec()</b> is called to match a compiled pattern <i>preg</i> +against a given <i>string</i>, which is terminated by a zero byte, subject to +the options in <i>eflags</i>.

If you are using private +tables, it is a little bit more complicated. +</P> +<P> +If you save compiled patterns to a file, you can copy them to a different host +and run them there. This works even if the new host has the opposite endianness +to the one on which the patterns were compiled. There may be a small +performance penalty, but it should be insignificant. +</P> +<br><a name="SEC2" href="#TOC1">SAVING A COMPILED PATTERN</a><br> +<P> +The value returned by <b>pcre_compile()</b> points to a single block of memory +that holds the compiled pattern and associated data. You can find the length of +this block in bytes by calling <b>pcre_fullinfo()</b> with an argument of +PCRE_INFO_SIZE. You can then save the data in any appropriate manner. Here is +sample code that compiles a pattern and writes it to a file. It assumes that +the variable <i>fd</i> refers to a file that is open for output: +<pre> + int erroroffset, rc, size; + char *error; + pcre *re; + + re = pcre_compile("my pattern", 0, &error, &erroroffset, NULL); + if (re == NULL) { ... handle errors ... } + rc = pcre_fullinfo(re, NULL, PCRE_INFO_SIZE, &size); + if (rc < 0) { ... handle errors ... } + rc = fwrite(re, 1, size, fd); + if (rc != size) { ... handle errors ... } +</pre> +In this example, the bytes that comprise the compiled pattern are copied +exactly. Note that this is binary data that may contain any of the 256 possible +byte values. On systems that make a distinction between binary and non-binary +data, be sure that the file is opened for binary output. +</P> +<P> +If you want to write more than one pattern to a file, you will have to devise a +way of separating them. For binary data, preceding each pattern with its length +is probably the most straightforward approach. Another possibility is to write +out the data in hexadecimal instead of binary, one pattern to a line. +</P> +<P> +Saving compiled patterns in a file is only one possible way of storing them for +later use. They could equally well be saved in a database, or in the memory of +some daemon process that passes them via sockets to the processes that want +them. +</P> +<P> +If the pattern has been studied, it is also possible to save the study data in +a similar way to the compiled pattern itself. When studying generates +additional information, <b>pcre_study()</b> returns a pointer to a +<b>pcre_extra</b> data block. Its format is defined in the +<a href="pcreapi.html#extradata">section on matching a pattern</a> +in the +<a href="pcreapi.html"><b>pcreapi</b></a> +documentation. The <i>study_data</i> field points to the binary study data, and +this is what you must save (not the <b>pcre_extra</b> block itself). The length +of the study data can be obtained by calling <b>pcre_fullinfo()</b> with an +argument of PCRE_INFO_STUDYSIZE. Remember to check that <b>pcre_study()</b> did +return a non-NULL value before trying to save the study data. +</P> +<br><a name="SEC3" href="#TOC1">RE-USING A PRECOMPILED PATTERN</a><br> +<P> +Re-using a precompiled pattern is straightforward. Having reloaded it into main +memory, you pass its pointer to <b>pcre_exec()</b> or <b>pcre_dfa_exec()</b> in +the usual way. This should work even on another host, and even if that host has +the opposite endianness to the one where the pattern was compiled. +</P> +<P> +However, if you passed a pointer to custom character tables when the pattern +was compiled (the <i>tableptr</i> argument of <b>pcre_compile()</b>), you must +now pass a similar pointer to <b>pcre_exec()</b> or <b>pcre_dfa_exec()</b>, +because the value saved with the compiled pattern will obviously be nonsense. A +field in a <b>pcre_extra()</b> block is used to pass this data, as described in +the +<a href="pcreapi.html#extradata">section on matching a pattern</a> +in the +<a href="pcreapi.html"><b>pcreapi</b></a> +documentation. +</P> +<P> +If you did not provide custom character tables when the pattern was compiled, +the pointer in the compiled pattern is NULL, which causes <b>pcre_exec()</b> to +use PCRE's internal tables. Thus, you do not need to take any special action at +run time in this case. +</P> +<P> +If you saved study data with the compiled pattern, you need to create your own +<b>pcre_extra</b> data block and set the <i>study_data</i> field to point to the +reloaded study data. You must also set the PCRE_EXTRA_STUDY_DATA bit in the +<i>flags</i> field to indicate that study data is present.

This calls itself recursively at branch points in the pattern, +in order to remember the state of the match so that it can back up and try a +different alternative if the first one fails. As matching proceeds deeper and +deeper into the tree of possibilities, the recursion depth increases. +</P> +<P> +Not all calls of <b>match()</b> increase the recursion depth; for an item such +as a* it may be called several times at the same level, after matching +different numbers of a's. Furthermore, in a number of cases where the result of +the recursive call would immediately be passed back as the result of the +current call (a "tail recursion"), the function is just restarted instead. +</P> +<P> +The <b>pcre_dfa_exec()</b> function operates in an entirely different way, and +hardly uses recursion at all. The limit on its complexity is the amount of +workspace it is given. The comments that follow do NOT apply to +<b>pcre_dfa_exec()</b>; they are relevant only for <b>pcre_exec()</b>. +</P> +<P> +You can set limits on the number of times that <b>match()</b> is called, both in +total and recursively. If the limit is exceeded, an error occurs. For details, +see the +<a href="pcreapi.html#extradata">section on extra data for <b>pcre_exec()</b></a> +in the +<a href="pcreapi.html"><b>pcreapi</b></a> +documentation. +</P> +<P> +Each time that <b>match()</b> is actually called recursively, it uses memory +from the process stack. For certain kinds of pattern and data, very large +amounts of stack may be needed, despite the recognition of "tail recursion". +You can often reduce the amount of recursion, and therefore the amount of stack +used, by modifying the pattern that is being matched. Consider, for example, +this pattern: +<pre> + ([^<]|<(?!inet))+ +</pre> +It matches from wherever it starts until it encounters "<inet" or the end of +the data, and is the kind of pattern that might be used when processing an XML +file. Each iteration of the outer parentheses matches either one character that +is not "<" or a "<" that is not followed by "inet". However, each time a +parenthesis is processed, a recursion occurs, so this formulation uses a stack +frame for each matched character. For a long string, a lot of stack is +required. Consider now this rewritten pattern, which matches exactly the same +strings: +<pre> + ([^<]++|<(?!inet)) +</pre> +This uses very much less stack, because runs of characters that do not contain +"<" are "swallowed" in one item inside the parentheses. Recursion happens only +when a "<" character that is not followed by "inet" is encountered (and we +assume this is relatively rare). A possessive quantifier is used to stop any +backtracking into the runs of non-"<" characters, but that is not related to +stack usage. +</P> +<P> +In environments where stack memory is constrained, you might want to compile +PCRE to use heap memory instead of stack for remembering back-up points. This +makes it run a lot more slowly, however. Details of how to do this are given in +the +<a href="pcrebuild.html"><b>pcrebuild</b></a> +documentation. +</P> +<P> +In Unix-like environments, there is not often a problem with the stack, though +the default limit on stack size varies from system to system. Values from 8Mb +to 64Mb are common. You can find your default limit by running the command: +<pre> + ulimit -s +</pre> +The effect of running out of stack is often SIGSEGV, though sometimes an error +message is given. You can normally increase the limit on stack size by code +such as this: +<pre> + struct rlimit rlim; + getrlimit(RLIMIT_STACK, &rlim); + rlim.rlim_cur = 100*1024*1024; + setrlimit(RLIMIT_STACK, &rlim); +</pre> +This reads the current limits (soft and hard) using <b>getrlimit()</b>, then +attempts to increase the soft limit to 100Mb using <b>setrlimit()</b>. You must +do this before calling <b>pcre_exec()</b>. +</P> +<P> +PCRE has an internal counter that can be used to limit the depth of recursion, +and thus cause <b>pcre_exec()</b> to give an error code before it runs out of +stack. By default, the limit is very large, and unlikely ever to operate. It +can be changed when PCRE is built, and it can also be set when +<b>pcre_exec()</b> is called. For details of these interfaces, see the +<a href="pcrebuild.html"><b>pcrebuild</b></a> +and +<a href="pcreapi.html"><b>pcreapi</b></a> +documentation. +</P> +<P> +As a very rough rule of thumb, you should reckon on about 500 bytes per +recursion. Thus, if you want to limit your stack usage to 8Mb, you +should set the limit at 16000 recursions. A 64Mb stack, on the other hand, can +support around 128000 recursions. The <b>pcretest</b> test program has a command +line option (<b>-S</b>) that can be used to increase its stack. +</P> +<P> +Last updated: 29 June 2006 +<br> +Copyright © 1997-2006 University of Cambridge. +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> Added: freeswitch/trunk/libs/pcre/doc/html/pcretest.html ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/doc/html/pcretest.html Tue Dec 19 14:54:26 2006 @@ -0,0 +1,616 @@ +<html> +<head> +<title>pcretest specification</title> +</head> +<body bgcolor="#FFFFFF" text="#00005A" link="#0066FF" alink="#3399FF" vlink="#2222BB"> +<h1>pcretest man page</h1> +<p> +Return to the <a href="index.html">PCRE index page</a>. +</p> +<p> +This page is part of the PCRE HTML documentation.

There is no limit on the length of data lines; the input +buffer is automatically extended if it is too small. +</P> +<P> +An empty line signals the end of the data lines, at which point a new regular +expression is read. The regular expressions are given enclosed in any +non-alphanumeric delimiters other than backslash, for example: +<pre> + /(a|bc)x+yz/ +</pre> +White space before the initial delimiter is ignored. A regular expression may +be continued over several input lines, in which case the newline characters are +included within it. It is possible to include the delimiter within the pattern +by escaping it, for example +<pre> + /abc\/def/ +</pre> +If you do so, the escape and the delimiter form part of the pattern, but since +delimiters are always non-alphanumeric, this does not affect its interpretation. +If the terminating delimiter is immediately followed by a backslash, for +example, +<pre> + /abc/\ +</pre> +then a backslash is added to the end of the pattern. This is done to provide a +way of testing the error condition that arises if a pattern finishes with a +backslash, because +<pre> + /abc\/ +</pre> +is interpreted as the first line of a pattern that starts with "abc/", causing +pcretest to read the next line as a continuation of the regular expression. +</P> +<br><a name="SEC4" href="#TOC1">PATTERN MODIFIERS</a><br> +<P> +A pattern may be followed by any number of modifiers, which are mostly single +characters. Following Perl usage, these are referred to below as, for example, +"the <b>/i</b> modifier", even though the delimiter of the pattern need not +always be a slash, and no slash is used when writing modifiers. Whitespace may +appear between the final pattern delimiter and the first modifier, and between +the modifiers themselves. +</P> +<P> +The <b>/i</b>, <b>/m</b>, <b>/s</b>, and <b>/x</b> modifiers set the PCRE_CASELESS, +PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED options, respectively, when +<b>pcre_compile()</b> is called. These four modifier letters have the same +effect as they do in Perl. For example: +<pre> + /caseless/i +</pre> +The following table shows additional modifiers for setting PCRE options that do +not correspond to anything in Perl: +<pre> + <b>/A</b> PCRE_ANCHORED + <b>/C</b> PCRE_AUTO_CALLOUT + <b>/E</b> PCRE_DOLLAR_ENDONLY + <b>/f</b> PCRE_FIRSTLINE + <b>/J</b> PCRE_DUPNAMES + <b>/N</b> PCRE_NO_AUTO_CAPTURE + <b>/U</b> PCRE_UNGREEDY + <b>/X</b> PCRE_EXTRA + <b>/<cr></b> PCRE_NEWLINE_CR + <b>/<lf></b> PCRE_NEWLINE_LF + <b>/<crlf></b> PCRE_NEWLINE_CRLF +</pre> +Those specifying line endings are literal strings as shown. Details of the +meanings of these PCRE options are given in the +<a href="pcreapi.html"><b>pcreapi</b></a> +documentation. +</P> +<br><b> +Finding all matches in a string +</b><br> +<P> +Searching for all possible matches within each subject string can be requested +by the <b>/g</b> or <b>/G</b> modifier. After finding a match, PCRE is called +again to search the remainder of the subject string. The difference between +<b>/g</b> and <b>/G</b> is that the former uses the <i>startoffset</i> argument to +<b>pcre_exec()</b> to start searching at a new point within the entire string +(which is in effect what Perl does), whereas the latter passes over a shortened +substring. This makes a difference to the matching process if the pattern +begins with a lookbehind assertion (including \b or \B). +</P> +<P> +If any call to <b>pcre_exec()</b> in a <b>/g</b> or <b>/G</b> sequence matches an +empty string, the next call is done with the PCRE_NOTEMPTY and PCRE_ANCHORED +flags set in order to search for another, non-empty, match at the same point. +If this second match fails, the start offset is advanced by one, and the normal +match is retried. This imitates the way Perl handles such cases when using the +<b>/g</b> modifier or the <b>split()</b> function. +</P> +<br><b> +Other modifiers +</b><br> +<P> +There are yet more modifiers for controlling the way <b>pcretest</b> +operates. +</P> +<P> +The <b>/+</b> modifier requests that as well as outputting the substring that +matched the entire pattern, pcretest should in addition output the remainder of +the subject string. This is useful for tests where the subject contains +multiple copies of the same substring. +</P> +<P> +The <b>/L</b> modifier must be followed directly by the name of a locale, for +example, +<pre> + /pattern/Lfr_FR +</pre> +For this reason, it must be the last modifier. The given locale is set, +<b>pcre_maketables()</b> is called to build a set of character tables for the +locale, and this is then passed to <b>pcre_compile()</b> when compiling the +regular expression. Without an <b>/L</b> modifier, NULL is passed as the tables +pointer; that is, <b>/L</b> applies only to the expression on which it appears. +</P> +<P> +The <b>/I</b> modifier requests that <b>pcretest</b> output information about the +compiled pattern (whether it is anchored, has a fixed first character, and +so on). It does this by calling <b>pcre_fullinfo()</b> after compiling a +pattern. If the pattern is studied, the results of that are also output. +</P> +<P> +The <b>/D</b> modifier is a PCRE debugging feature, which also assumes <b>/I</b>. +It causes the internal form of compiled regular expressions to be output after +compilation. If the pattern was studied, the information returned is also +output. +</P> +<P> +The <b>/F</b> modifier causes <b>pcretest</b> to flip the byte order of the +fields in the compiled pattern that contain 2-byte and 4-byte numbers. This +facility is for testing the feature in PCRE that allows it to execute patterns +that were compiled on a host with a different endianness. This feature is not +available when the POSIX interface to PCRE is being used, that is, when the +<b>/P</b> pattern modifier is specified. See also the section about saving and +reloading compiled patterns below. +</P> +<P> +The <b>/S</b> modifier causes <b>pcre_study()</b> to be called after the +expression has been compiled, and the results used when the expression is +matched. +</P> +<P> +The <b>/M</b> modifier causes the size of memory block used to hold the compiled +pattern to be output. +</P> +<P> +The <b>/P</b> modifier causes <b>pcretest</b> to call PCRE via the POSIX wrapper +API rather than its native API. When this is done, all other modifiers except +<b>/i</b>, <b>/m</b>, and <b>/+</b> are ignored. REG_ICASE is set if <b>/i</b> is +present, and REG_NEWLINE is set if <b>/m</b> is present. The wrapper functions +force PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set. +</P> +<P> +The <b>/8</b> modifier causes <b>pcretest</b> to call PCRE with the PCRE_UTF8 +option set. This turns on support for UTF-8 character handling in PCRE, +provided that it was compiled with this support enabled. This modifier also +causes any non-printing characters in output strings to be printed using the +\x{hh...} notation if they are valid UTF-8 sequences. +</P> +<P> +If the <b>/?</b> modifier is used with <b>/8</b>, it causes <b>pcretest</b> to +call <b>pcre_compile()</b> with the PCRE_NO_UTF8_CHECK option, to suppress the +checking of the string for UTF-8 validity. +</P> +<br><a name="SEC5" href="#TOC1">DATA LINES</a><br> +<P> +Before each data line is passed to <b>pcre_exec()</b>, leading and trailing +whitespace is removed, and it is then scanned for \ escapes.

From release 6.0, PCRE supports an +alternative matching function, <b>pcre_dfa_test()</b>, which operates in a +different way, and has some restrictions. The differences between the two +functions are described in the +<a href="pcrematching.html"><b>pcrematching</b></a> +documentation. +</P> +<P> +If a data line contains the \D escape sequence, or if the command line +contains the <b>-dfa</b> option, the alternative matching function is called. +This function finds all possible matches at a given point. If, however, the \F +escape sequence is present in the data line, it stops after the first match is +found. This is always the shortest possible match. +</P> +<br><a name="SEC7" href="#TOC1">DEFAULT OUTPUT FROM PCRETEST</a><br> +<P> +This section describes the output when the normal matching function, +<b>pcre_exec()</b>, is being used. +</P> +<P> +When a match succeeds, pcretest outputs the list of captured substrings that +<b>pcre_exec()</b> returns, starting with number 0 for the string that matched +the whole pattern. Otherwise, it outputs "No match" or "Partial match" +when <b>pcre_exec()</b> returns PCRE_ERROR_NOMATCH or PCRE_ERROR_PARTIAL, +respectively, and otherwise the PCRE negative error number. Here is an example +of an interactive <b>pcretest</b> run. +<pre> + $ pcretest + PCRE version 5.00 07-Sep-2004 + + re> /^abc(\d+)/ + data> abc123 + 0: abc123 + 1: 123 + data> xyz + No match +</pre> +If the strings contain any non-printing characters, they are output as \0x +escapes, or as \x{...} escapes if the <b>/8</b> modifier was present on the +pattern. If the pattern has the <b>/+</b> modifier, the output for substring 0 +is followed by the the rest of the subject string, identified by "0+" like +this: +<pre> + re> /cat/+ + data> cataract + 0: cat + 0+ aract +</pre> +If the pattern has the <b>/g</b> or <b>/G</b> modifier, the results of successive +matching attempts are output in sequence, like this: +<pre> + re> /\Bi(\w\w)/g + data> Mississippi + 0: iss + 1: ss + 0: iss + 1: ss + 0: ipp + 1: pp +</pre> +"No match" is output only if the first match attempt fails. +</P> +<P> +If any of the sequences <b>\C</b>, <b>\G</b>, or <b>\L</b> are present in a +data line that is successfully matched, the substrings extracted by the +convenience functions are output with C, G, or L after the string number +instead of a colon. This is in addition to the normal full list. The string +length (that is, the return from the extraction function) is given in +parentheses after each string for <b>\C</b> and <b>\G</b>. +</P> +<P> +Note that while patterns can be continued over several lines (a plain ">" +prompt is used for continuations), data lines may not. However newlines can be +included in data by means of the \n escape (or \r or \r\n for those newline +settings). +</P> +<br><a name="SEC8" href="#TOC1">OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION</a><br> +<P> +When the alternative matching function, <b>pcre_dfa_exec()</b>, is used (by +means of the \D escape sequence or the <b>-dfa</b> command line option), the +output consists of a list of all the matches that start at the first point in +the subject where there is at least one match. For example: +<pre> + re> /(tang|tangerine|tan)/ + data> yellow tangerine\D + 0: tangerine + 1: tang + 2: tan +</pre> +(Using the normal matching function on this data finds only "tang".) The +longest matching string is always given first (and numbered zero). +</P> +<P> +If \fB/g\P is present on the pattern, the search for further matches resumes +at the end of the longest match. For example: +<pre> + re> /(tang|tangerine|tan)/g + data> yellow tangerine and tangy sultana\D + 0: tangerine + 1: tang + 2: tan + 0: tang + 1: tan + 0: tan +</pre> +Since the matching function does not support substring capture, the escape +sequences that are concerned with captured substrings are not relevant. +</P> +<br><a name="SEC9" href="#TOC1">RESTARTING AFTER A PARTIAL MATCH</a><br> +<P> +When the alternative matching function has given the PCRE_ERROR_PARTIAL return, +indicating that the subject partially matched the pattern, you can restart the +match with additional subject data by means of the \R escape sequence. For +example: +<pre> + re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/ + data> 23ja\P\D + Partial match: 23ja + data> n05\R\D + 0: n05 +</pre> +For further information about partial matching, see the +<a href="pcrepartial.html"><b>pcrepartial</b></a> +documentation. +</P> +<br><a name="SEC10" href="#TOC1">CALLOUTS</a><br> +<P> +If the pattern contains any callout requests, <b>pcretest</b>'s callout function +is called during matching. This works with both matching functions. By default, +the called function displays the callout number, the start and current +positions in the text at the callout time, and the next pattern item to be +tested. For example, the output +<pre> + --->pqrabcdef + 0 ^ ^ \d +</pre> +indicates that callout number 0 occurred for a match attempt starting at the +fourth character of the subject string, when the pointer was at the seventh +character of the data, and when the next pattern item was \d.

If you want to process +regular expressions that are truly enormous, you can compile PCRE with an +internal linkage size of 3 or 4 (see the \fBREADME\fP file in the source +distribution and the +.\" HREF +\fBpcrebuild\fP +.\" +documentation for details). In these cases the limit is substantially larger. +However, the speed of execution will be slower. +.P +All values in repeating quantifiers must be less than 65536. The maximum +compiled length of subpattern with an explicit repeat count is 30000 bytes. The +maximum number of capturing subpatterns is 65535. +.P +There is no limit to the number of non-capturing subpatterns, but the maximum +depth of nesting of all kinds of parenthesized subpattern, including capturing +subpatterns, assertions, and other types of subpattern, is 200. +.P +The maximum length of name for a named subpattern is 32, and the maximum number +of named subpatterns is 10000. +.P +The maximum length of a subject string is the largest positive number that an +integer variable can hold. However, when using the traditional matching +function, PCRE uses recursion to handle subpatterns and indefinite repetition. +This means that the available stack space may limit the size of a subject +string that can be processed by certain patterns. For a discussion of stack +issues, see the +.\" HREF +\fBpcrestack\fP +.\" +documentation. +.sp +.\" HTML <a name="utf8support"></a> +. +. +.SH "UTF-8 AND UNICODE PROPERTY SUPPORT" +.rs +.sp +From release 3.3, PCRE has had some support for character strings encoded in +the UTF-8 format. For release 4.0 this was greatly extended to cover most +common requirements, and in release 5.0 additional support for Unicode general +category properties was added. +.P +In order process UTF-8 strings, you must build PCRE to include UTF-8 support in +the code, and, in addition, you must call +.\" HREF +\fBpcre_compile()\fP +.\" +with the PCRE_UTF8 option flag. When you do this, both the pattern and any +subject strings that are matched against it are treated as UTF-8 strings +instead of just strings of bytes. +.P +If you compile PCRE with UTF-8 support, but do not use it at run time, the +library will be a bit bigger, but the additional run time overhead is limited +to testing the PCRE_UTF8 flag in several places, so should not be very large. +.P +If PCRE is built with Unicode character property support (which implies UTF-8 +support), the escape sequences \ep{..}, \eP{..}, and \eX are supported. +The available properties that can be tested are limited to the general +category properties such as Lu for an upper case letter or Nd for a decimal +number, the Unicode script names such as Arabic or Han, and the derived +properties Any and L&. A full list is given in the +.\" HREF +\fBpcrepattern\fP +.\" +documentation. Only the short names for properties are supported. For example, +\ep{L} matches a letter. Its Perl synonym, \ep{Letter}, is not supported. +Furthermore, in Perl, many properties may optionally be prefixed by "Is", for +compatibility with Perl 5.6. PCRE does not support this. +.P +The following comments apply when PCRE is running in UTF-8 mode: +.P +1. When you set the PCRE_UTF8 flag, the strings passed as patterns and subjects +are checked for validity on entry to the relevant functions. If an invalid +UTF-8 string is passed, an error return is given. In some situations, you may +already know that your strings are valid, and therefore want to skip these +checks in order to improve performance. If you set the PCRE_NO_UTF8_CHECK flag +at compile time or at run time, PCRE assumes that the pattern or subject it +is given (respectively) contains only valid UTF-8 codes. In this case, it does +not diagnose an invalid UTF-8 string. If you pass an invalid UTF-8 string to +PCRE when PCRE_NO_UTF8_CHECK is set, the results are undefined. Your program +may crash. +.P +2. An unbraced hexadecimal escape sequence (such as \exb3) matches a two-byte +UTF-8 character if the value is greater than 127. +.P +3. Octal numbers up to \e777 are recognized, and match two-byte UTF-8 +characters for values greater than \e177. +.P +4. Repeat quantifiers apply to complete UTF-8 characters, not to individual +bytes, for example: \ex{100}{3}. +.P +5. The dot metacharacter matches one UTF-8 character instead of a single byte. +.P +6. The escape sequence \eC can be used to match a single byte in UTF-8 mode, +but its use can lead to some strange effects. This facility is not available in +the alternative matching function, \fBpcre_dfa_exec()\fP. +.P +7. The character escapes \eb, \eB, \ed, \eD, \es, \eS, \ew, and \eW correctly +test characters of any code value, but the characters that PCRE recognizes as +digits, spaces, or word characters remain the same set as before, all with +values less than 256. This remains true even when PCRE includes Unicode +property support, because to do otherwise would slow down PCRE in many common +cases. If you really want to test for a wider sense of, say, "digit", you +must use Unicode property tests such as \ep{Nd}. +.P +8. Similarly, characters that match the POSIX named character classes are all +low-valued characters. +.P +9. Case-insensitive matching applies only to characters whose values are less +than 128, unless PCRE is built with Unicode property support. Even when Unicode +property support is available, PCRE still uses its own character tables when +checking the case of low-valued characters, so as not to degrade performance. +The Unicode property information is used only for characters with higher +values. Even when Unicode property support is available, PCRE supports +case-insensitive matching only when there is a one-to-one mapping between a +letter's cases. There are a small number of many-to-one mappings in Unicode; +these are not supported by PCRE. +. +.SH AUTHOR +.rs +.sp +Philip Hazel +.br +University Computing Service, +.br +Cambridge CB2 3QG, England. +.P +Putting an actual email address here seems to have been a spam magnet, so I've +taken it away.

However, when using the traditional + matching function, PCRE uses recursion to handle subpatterns and indef- + inite repetition. This means that the available stack space may limit + the size of a subject string that can be processed by certain patterns. + For a discussion of stack issues, see the pcrestack documentation. + + +UTF-8 AND UNICODE PROPERTY SUPPORT + + From release 3.3, PCRE has had some support for character strings + encoded in the UTF-8 format. For release 4.0 this was greatly extended + to cover most common requirements, and in release 5.0 additional sup- + port for Unicode general category properties was added. + + In order process UTF-8 strings, you must build PCRE to include UTF-8 + support in the code, and, in addition, you must call pcre_compile() + with the PCRE_UTF8 option flag. When you do this, both the pattern and + any subject strings that are matched against it are treated as UTF-8 + strings instead of just strings of bytes. + + If you compile PCRE with UTF-8 support, but do not use it at run time, + the library will be a bit bigger, but the additional run time overhead + is limited to testing the PCRE_UTF8 flag in several places, so should + not be very large. + + If PCRE is built with Unicode character property support (which implies + UTF-8 support), the escape sequences \p{..}, \P{..}, and \X are sup- + ported. The available properties that can be tested are limited to the + general category properties such as Lu for an upper case letter or Nd + for a decimal number, the Unicode script names such as Arabic or Han, + and the derived properties Any and L&. A full list is given in the + pcrepattern documentation. Only the short names for properties are sup- + ported. For example, \p{L} matches a letter. Its Perl synonym, \p{Let- + ter}, is not supported. Furthermore, in Perl, many properties may + optionally be prefixed by "Is", for compatibility with Perl 5.6. PCRE + does not support this. + + The following comments apply when PCRE is running in UTF-8 mode: + + 1. When you set the PCRE_UTF8 flag, the strings passed as patterns and + subjects are checked for validity on entry to the relevant functions. + If an invalid UTF-8 string is passed, an error return is given. In some + situations, you may already know that your strings are valid, and + therefore want to skip these checks in order to improve performance. If + you set the PCRE_NO_UTF8_CHECK flag at compile time or at run time, + PCRE assumes that the pattern or subject it is given (respectively) + contains only valid UTF-8 codes. In this case, it does not diagnose an + invalid UTF-8 string. If you pass an invalid UTF-8 string to PCRE when + PCRE_NO_UTF8_CHECK is set, the results are undefined. Your program may + crash. + + 2. An unbraced hexadecimal escape sequence (such as \xb3) matches a + two-byte UTF-8 character if the value is greater than 127. + + 3. Octal numbers up to \777 are recognized, and match two-byte UTF-8 + characters for values greater than \177. + + 4. Repeat quantifiers apply to complete UTF-8 characters, not to indi- + vidual bytes, for example: \x{100}{3}. + + 5. The dot metacharacter matches one UTF-8 character instead of a sin- + gle byte. + + 6. The escape sequence \C can be used to match a single byte in UTF-8 + mode, but its use can lead to some strange effects. This facility is + not available in the alternative matching function, pcre_dfa_exec(). + + 7. The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly + test characters of any code value, but the characters that PCRE recog- + nizes as digits, spaces, or word characters remain the same set as + before, all with values less than 256. This remains true even when PCRE + includes Unicode property support, because to do otherwise would slow + down PCRE in many common cases. If you really want to test for a wider + sense of, say, "digit", you must use Unicode property tests such as + \p{Nd}. + + 8. Similarly, characters that match the POSIX named character classes + are all low-valued characters. + + 9. Case-insensitive matching applies only to characters whose values + are less than 128, unless PCRE is built with Unicode property support. + Even when Unicode property support is available, PCRE still uses its + own character tables when checking the case of low-valued characters, + so as not to degrade performance. The Unicode property information is + used only for characters with higher values. Even when Unicode property + support is available, PCRE supports case-insensitive matching only when + there is a one-to-one mapping between a letter's cases. There are a + small number of many-to-one mappings in Unicode; these are not sup- + ported by PCRE. + + +AUTHOR + + Philip Hazel + University Computing Service, + Cambridge CB2 3QG, England. + + Putting an actual email address here seems to have been a spam magnet, + so I've taken it away.

They are all selected, or dese- + lected, by providing options to the configure script that is run before + the make command. The complete list of options for configure (which + includes the standard ones such as the selection of the installation + directory) can be obtained by running + + ./configure --help + + The following sections describe certain options whose names begin with + --enable or --disable. These settings specify changes to the defaults + for the configure command. Because of the way that configure works, + --enable and --disable always come in pairs, so the complementary + option always exists as well, but as it specifies the default, it is + not described. + + +C++ SUPPORT + + By default, the configure script will search for a C++ compiler and C++ + header files. If it finds them, it automatically builds the C++ wrapper + library for PCRE. You can disable this by adding + + --disable-cpp + + to the configure command. + + +UTF-8 SUPPORT + + To build PCRE with support for UTF-8 character strings, add + + --enable-utf8 + + to the configure command. Of itself, this does not make PCRE treat + strings as UTF-8. As well as compiling PCRE with this option, you also + have have to set the PCRE_UTF8 option when you call the pcre_compile() + function. + + +UNICODE CHARACTER PROPERTY SUPPORT + + UTF-8 support allows PCRE to process character values greater than 255 + in the strings that it handles. On its own, however, it does not pro- + vide any facilities for accessing the properties of such characters. If + you want to be able to use the pattern escapes \P, \p, and \X, which + refer to Unicode character properties, you must add + + --enable-unicode-properties + + to the configure command. This implies UTF-8 support, even if you have + not explicitly requested it. + + Including Unicode property support adds around 90K of tables to the + PCRE library, approximately doubling its size. Only the general cate- + gory properties such as Lu and Nd are supported. Details are given in + the pcrepattern documentation. + + +CODE VALUE OF NEWLINE + + By default, PCRE interprets character 10 (linefeed, LF) as indicating + the end of a line. This is the normal newline character on Unix-like + systems. You can compile PCRE to use character 13 (carriage return, CR) + instead, by adding + + --enable-newline-is-cr + + to the configure command. There is also a --enable-newline-is-lf + option, which explicitly specifies linefeed as the newline character. + + Alternatively, you can specify that line endings are to be indicated by + the two character sequence CRLF. If you want this, add + + --enable-newline-is-crlf + + to the configure command. Whatever line ending convention is selected + when PCRE is built can be overridden when the library functions are + called. At build time it is conventional to use the standard for your + operating system. + + +BUILDING SHARED AND STATIC LIBRARIES + + The PCRE building process uses libtool to build both shared and static + Unix libraries by default. You can suppress one of these by adding one + of + + --disable-shared + --disable-static + + to the configure command, as required. + + +POSIX MALLOC USAGE + + When PCRE is called through the POSIX interface (see the pcreposix doc- + umentation), additional working storage is required for holding the + pointers to capturing substrings, because PCRE requires three integers + per substring, whereas the POSIX interface provides only two. If the + number of expected substrings is small, the wrapper function uses space + on the stack, because this is faster than using malloc() for each call. + The default threshold above which the stack is no longer used is 10; it + can be changed by adding a setting such as + + --with-posix-malloc-threshold=20 + + to the configure command. + + +HANDLING VERY LARGE PATTERNS + + Within a compiled pattern, offset values are used to point from one + part to another (for example, from an opening parenthesis to an alter- + nation metacharacter). By default, two-byte values are used for these + offsets, leading to a maximum size for a compiled pattern of around + 64K. This is sufficient to handle all but the most gigantic patterns. + Nevertheless, some people do want to process enormous patterns, so it + is possible to compile PCRE to use three-byte or four-byte offsets by + adding a setting such as + + --with-link-size=3 + + to the configure command. The value given must be 2, 3, or 4. Using + longer offsets slows down the operation of PCRE because it has to load + additional bytes when handling them. + + If you build PCRE with an increased link size, test 2 (and test 5 if + you are using UTF-8) will fail. Part of the output of these tests is a + representation of the compiled pattern, and this changes with the link + size. + + +AVOIDING EXCESSIVE STACK USAGE + + When matching with the pcre_exec() function, PCRE implements backtrack- + ing by making recursive calls to an internal function called match(). + In environments where the size of the stack is limited, this can se- + verely limit PCRE's operation. (The Unix environment does not usually + suffer from this problem, but it may sometimes be necessary to increase + the maximum stack size. There is a discussion in the pcrestack docu- + mentation.) An alternative approach to recursion that uses memory from + the heap to remember data, instead of using recursive function calls, + has been implemented to work round the problem of limited stack size. + If you want to build a version of PCRE that works this way, add + + --disable-stack-for-recursion + + to the configure command. With this configuration, PCRE will use the + pcre_stack_malloc and pcre_stack_free variables to call memory manage- + ment functions. Separate functions are provided because the usage is + very predictable: the block sizes requested are always the same, and + the blocks are always freed in reverse order. A calling program might + be able to implement optimized functions that perform better than the + standard malloc() and free() functions. PCRE runs noticeably more + slowly when built in this way. This option affects only the pcre_exec() + function; it is not relevant for the the pcre_dfa_exec() function. + + +LIMITING PCRE RESOURCE USAGE + + Internally, PCRE has a function called match(), which it calls repeat- + edly (sometimes recursively) when matching a pattern with the + pcre_exec() function. By controlling the maximum number of times this + function may be called during a single matching operation, a limit can + be placed on the resources used by a single call to pcre_exec(). The + limit can be changed at run time, as described in the pcreapi documen- + tation. The default is 10 million, but this can be changed by adding a + setting such as + + --with-match-limit=500000 + + to the configure command. This setting has no effect on the + pcre_dfa_exec() matching function. + + In some environments it is desirable to limit the depth of recursive + calls of match() more strictly than the total number of calls, in order + to restrict the maximum amount of stack (or heap, if --disable-stack- + for-recursion is specified) that is used. A second limit controls this; + it defaults to the value that is set for --with-match-limit, which + imposes no additional constraints. However, you can set a lower limit + by adding, for example, + + --with-match-limit-recursion=10000 + + to the configure command. This value can also be overridden at run + time. + + +USING EBCDIC CODE + + PCRE assumes by default that it will run in an environment where the + character code is ASCII (or Unicode, which is a superset of ASCII). + PCRE can, however, be compiled to run in an EBCDIC environment by + adding + + --enable-ebcdic + + to the configure command. + +Last updated: 06 June 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + +PCREMATCHING(3) PCREMATCHING(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +PCRE MATCHING ALGORITHMS + + This document describes the two different algorithms that are available + in PCRE for matching a compiled regular expression against a given sub- + ject string. The "standard" algorithm is the one provided by the + pcre_exec() function. This works in the same was as Perl's matching + function, and provides a Perl-compatible matching operation. + + An alternative algorithm is provided by the pcre_dfa_exec() function; + this operates in a different way, and is not Perl-compatible. It has + advantages and disadvantages compared with the standard algorithm, and + these are described below. + + When there is only one possible way in which a given subject string can + match a pattern, the two algorithms give the same answer. A difference + arises, however, when there are multiple possibilities. For example, if + the pattern + + ^<.*> + + is matched against the string + + <something> <something else> <something further> + + there are three possible answers. The standard algorithm finds only one + of them, whereas the DFA algorithm finds all three. + + +REGULAR EXPRESSIONS AS TREES + + The set of strings that are matched by a regular expression can be rep- + resented as a tree structure. An unlimited repetition in the pattern + makes the tree of infinite size, but it is still a tree. Matching the + pattern to a given subject string (from a given starting point) can be + thought of as a search of the tree. There are two ways to search a + tree: depth-first and breadth-first, and these correspond to the two + matching algorithms provided by PCRE. + + +THE STANDARD MATCHING ALGORITHM + + In the terminology of Jeffrey Friedl's book Mastering Regular Expres- + sions, the standard algorithm is an "NFA algorithm". It conducts a + depth-first search of the pattern tree. That is, it proceeds along a + single path through the tree, checking that the subject matches what is + required. When there is a mismatch, the algorithm tries any alterna- + tives at the current point, and if they all fail, it backs up to the + previous branch point in the tree, and tries the next alternative + branch at that level. This often involves backing up (moving to the + left) in the subject string as well. The order in which repetition + branches are tried is controlled by the greedy or ungreedy nature of + the quantifier. + + If a leaf node is reached, a matching string has been found, and at + that point the algorithm stops. Thus, if there is more than one possi- + ble match, this algorithm returns the first one that it finds. Whether + this is the shortest, the longest, or some intermediate length depends + on the way the greedy and ungreedy repetition quantifiers are specified + in the pattern. + + Because it ends up with a single path through the tree, it is rela- + tively straightforward for this algorithm to keep track of the sub- + strings that are matched by portions of the pattern in parentheses. + This provides support for capturing parentheses and back references. + + +THE DFA MATCHING ALGORITHM + + DFA stands for "deterministic finite automaton", but you do not need to + understand the origins of that name. This algorithm conducts a breadth- + first search of the tree. Starting from the first matching point in the + subject, it scans the subject string from left to right, once, charac- + ter by character, and as it does this, it remembers all the paths + through the tree that represent valid matches. + + The scan continues until either the end of the subject is reached, or + there are no more unterminated paths. At this point, terminated paths + represent the different matching possibilities (if there are none, the + match has failed). Thus, if there is more than one possible match, + this algorithm finds all of them, and in particular, it finds the long- + est. In PCRE, there is an option to stop the algorithm after the first + match (which is necessarily the shortest) has been found. + + Note that all the matches that are found start at the same point in the + subject. If the pattern + + cat(er(pillar)?) + + is matched against the string "the caterpillar catchment", the result + will be the three strings "cat", "cater", and "caterpillar" that start + at the fourth character of the subject. The algorithm does not automat- + ically move on to find matches that start at later positions. + + There are a number of features of PCRE regular expressions that are not + supported by the DFA matching algorithm. They are as follows: + + 1. Because the algorithm finds all possible matches, the greedy or + ungreedy nature of repetition quantifiers is not relevant. Greedy and + ungreedy quantifiers are treated in exactly the same way. + + 2. When dealing with multiple paths through the tree simultaneously, it + is not straightforward to keep track of captured substrings for the + different matching possibilities, and PCRE's implementation of this + algorithm does not attempt to do this. This means that no captured sub- + strings are available. + + 3. Because no substrings are captured, back references within the pat- + tern are not supported, and cause errors if encountered. + + 4. For the same reason, conditional expressions that use a backrefer- + ence as the condition are not supported. + + 5. Callouts are supported, but the value of the capture_top field is + always 1, and the value of the capture_last field is always -1. + + 6. The \C escape sequence, which (in the standard algorithm) matches a + single byte, even in UTF-8 mode, is not supported because the DFA algo- + rithm moves through the subject string one character at a time, for all + active paths through the tree. + + +ADVANTAGES OF THE DFA ALGORITHM + + Using the DFA matching algorithm provides the following advantages: + + 1. All possible matches (at a single point in the subject) are automat- + ically found, and in particular, the longest match is found. To find + more than one match using the standard algorithm, you have to do kludgy + things with callouts. + + 2. There is much better support for partial matching. The restrictions + on the content of the pattern that apply when using the standard algo- + rithm for partial matching do not apply to the DFA algorithm. For non- + anchored patterns, the starting position of a partial match is avail- + able. + + 3. Because the DFA algorithm scans the subject string just once, and + never needs to backtrack, it is possible to pass very long subject + strings to the matching function in several pieces, checking for par- + tial matching each time. + + +DISADVANTAGES OF THE DFA ALGORITHM + + The DFA algorithm suffers from a number of disadvantages: + + 1. It is substantially slower than the standard algorithm. This is + partly because it has to search for all possible matches, but is also + because it is less susceptible to optimization. + + 2. Capturing parentheses and back references are not supported. + + 3. The "atomic group" feature of PCRE regular expressions is supported, + but does not provide the advantage that it does for the standard algo- + rithm. + +Last updated: 06 June 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + +PCREAPI(3) PCREAPI(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +PCRE NATIVE API + + #include <pcre.h> + + pcre *pcre_compile(const char *pattern, int options, + const char **errptr, int *erroffset, + const unsigned char *tableptr); + + pcre *pcre_compile2(const char *pattern, int options, + int *errorcodeptr, + const char **errptr, int *erroffset, + const unsigned char *tableptr); + + pcre_extra *pcre_study(const pcre *code, int options, + const char **errptr); + + int pcre_exec(const pcre *code, const pcre_extra *extra, + const char *subject, int length, int startoffset, + int options, int *ovector, int ovecsize); + + int pcre_dfa_exec(const pcre *code, const pcre_extra *extra, + const char *subject, int length, int startoffset, + int options, int *ovector, int ovecsize, + int *workspace, int wscount); + + int pcre_copy_named_substring(const pcre *code, + const char *subject, int *ovector, + int stringcount, const char *stringname, + char *buffer, int buffersize); + + int pcre_copy_substring(const char *subject, int *ovector, + int stringcount, int stringnumber, char *buffer, + int buffersize); + + int pcre_get_named_substring(const pcre *code, + const char *subject, int *ovector, + int stringcount, const char *stringname, + const char **stringptr); + + int pcre_get_stringnumber(const pcre *code, + const char *name); + + int pcre_get_stringtable_entries(const pcre *code, + const char *name, char **first, char **last); + + int pcre_get_substring(const char *subject, int *ovector, + int stringcount, int stringnumber, + const char **stringptr); + + int pcre_get_substring_list(const char *subject, + int *ovector, int stringcount, const char ***listptr); + + void pcre_free_substring(const char *stringptr); + + void pcre_free_substring_list(const char **stringptr); + + const unsigned char *pcre_maketables(void); + + int pcre_fullinfo(const pcre *code, const pcre_extra *extra, + int what, void *where); + + int pcre_info(const pcre *code, int *optptr, int *firstcharptr); + + int pcre_refcount(pcre *code, int adjust); + + int pcre_config(int what, void *where); + + char *pcre_version(void); + + void *(*pcre_malloc)(size_t); + + void (*pcre_free)(void *); + + void *(*pcre_stack_malloc)(size_t); + + void (*pcre_stack_free)(void *); + + int (*pcre_callout)(pcre_callout_block *); + + +PCRE API OVERVIEW + + PCRE has its own native API, which is described in this document. There + is also a set of wrapper functions that correspond to the POSIX regular + expression API. These are described in the pcreposix documentation. + Both of these APIs define a set of C function calls. A C++ wrapper is + distributed with PCRE. It is documented in the pcrecpp page. + + The native API C function prototypes are defined in the header file + pcre.h, and on Unix systems the library itself is called libpcre. It + can normally be accessed by adding -lpcre to the command for linking an + application that uses PCRE. The header file defines the macros + PCRE_MAJOR and PCRE_MINOR to contain the major and minor release num- + bers for the library. Applications can use these to include support + for different releases of PCRE. + + The functions pcre_compile(), pcre_compile2(), pcre_study(), and + pcre_exec() are used for compiling and matching regular expressions in + a Perl-compatible manner. A sample program that demonstrates the sim- + plest way of using them is provided in the file called pcredemo.c in + the source distribution. The pcresample documentation describes how to + run it. + + A second matching function, pcre_dfa_exec(), which is not Perl-compati- + ble, is also provided. This uses a different algorithm for the match- + ing. The alternative algorithm finds all possible matches (at a given + point in the subject). However, this algorithm does not return captured + substrings. A description of the two matching algorithms and their + advantages and disadvantages is given in the pcrematching documenta- + tion. + + In addition to the main compiling and matching functions, there are + convenience functions for extracting captured substrings from a subject + string that is matched by pcre_exec(). They are: + + pcre_copy_substring() + pcre_copy_named_substring() + pcre_get_substring() + pcre_get_named_substring() + pcre_get_substring_list() + pcre_get_stringnumber() + pcre_get_stringtable_entries() + + pcre_free_substring() and pcre_free_substring_list() are also provided, + to free the memory used for extracted strings. + + The function pcre_maketables() is used to build a set of character + tables in the current locale for passing to pcre_compile(), + pcre_exec(), or pcre_dfa_exec(). This is an optional facility that is + provided for specialist use. Most commonly, no special tables are + passed, in which case internal tables that are generated when PCRE is + built are used. + + The function pcre_fullinfo() is used to find out information about a + compiled pattern; pcre_info() is an obsolete version that returns only + some of the available information, but is retained for backwards com- + patibility. The function pcre_version() returns a pointer to a string + containing the version of PCRE and its date of release. + + The function pcre_refcount() maintains a reference count in a data + block containing a compiled pattern. This is provided for the benefit + of object-oriented applications. + + The global variables pcre_malloc and pcre_free initially contain the + entry points of the standard malloc() and free() functions, respec- + tively. PCRE calls the memory management functions via these variables, + so a calling program can replace them if it wishes to intercept the + calls. This should be done before calling any PCRE functions. + + The global variables pcre_stack_malloc and pcre_stack_free are also + indirections to memory management functions. These special functions + are used only when PCRE is compiled to use the heap for remembering + data, instead of recursive function calls, when running the pcre_exec() + function. See the pcrebuild documentation for details of how to do + this. It is a non-standard way of building PCRE, for use in environ- + ments that have limited stacks. Because of the greater use of memory + management, it runs more slowly. Separate functions are provided so + that special-purpose external code can be used for this case. When + used, these functions are always called in a stack-like manner (last + obtained, first freed), and always for memory blocks of the same size. + There is a discussion about PCRE's stack usage in the pcrestack docu- + mentation. + + The global variable pcre_callout initially contains NULL. It can be set + by the caller to a "callout" function, which PCRE will then call at + specified points during a matching operation. Details are given in the + pcrecallout documentation. + + +NEWLINES + PCRE supports three different conventions for indicating line breaks in + strings: a single CR character, a single LF character, or the two-char- + acter sequence CRLF. All three are used as "standard" by different + operating systems. When PCRE is built, a default can be specified. The + default default is LF, which is the Unix standard. When PCRE is run, + the default can be overridden, either when a pattern is compiled, or + when it is matched. + + In the PCRE documentation the word "newline" is used to mean "the char- + acter or pair of characters that indicate a line break". + + +MULTITHREADING + + The PCRE functions can be used in multi-threading applications, with + the proviso that the memory management functions pointed to by + pcre_malloc, pcre_free, pcre_stack_malloc, and pcre_stack_free, and the + callout function pointed to by pcre_callout, are shared by all threads. + + The compiled form of a regular expression is not altered during match- + ing, so the same compiled pattern can safely be used by several threads + at once. + + +SAVING PRECOMPILED PATTERNS FOR LATER USE + + The compiled form of a regular expression can be saved and re-used at a + later time, possibly by a different program, and even on a host other + than the one on which it was compiled. Details are given in the + pcreprecompile documentation. + + +CHECKING BUILD-TIME OPTIONS + + int pcre_config(int what, void *where); + + The function pcre_config() makes it possible for a PCRE client to dis- + cover which optional features have been compiled into the PCRE library. + The pcrebuild documentation has more details about these optional fea- + tures. + + The first argument for pcre_config() is an integer, specifying which + information is required; the second argument is a pointer to a variable + into which the information is placed. The following information is + available: + + PCRE_CONFIG_UTF8 + + The output is an integer that is set to one if UTF-8 support is avail- + able; otherwise it is set to zero. + + PCRE_CONFIG_UNICODE_PROPERTIES + + The output is an integer that is set to one if support for Unicode + character properties is available; otherwise it is set to zero. + + PCRE_CONFIG_NEWLINE + + The output is an integer whose value specifies the default character + sequence that is recognized as meaning "newline". The three values that + are supported are: 10 for LF, 13 for CR, and 3338 for CRLF. The default + should normally be the standard sequence for your operating system. + + PCRE_CONFIG_LINK_SIZE + + The output is an integer that contains the number of bytes used for + internal linkage in compiled regular expressions. The value is 2, 3, or + 4. Larger values allow larger regular expressions to be compiled, at + the expense of slower matching. The default value of 2 is sufficient + for all but the most massive patterns, since it allows the compiled + pattern to be up to 64K in size. + + PCRE_CONFIG_POSIX_MALLOC_THRESHOLD + + The output is an integer that contains the threshold above which the + POSIX interface uses malloc() for output vectors. Further details are + given in the pcreposix documentation. + + PCRE_CONFIG_MATCH_LIMIT + + The output is an integer that gives the default limit for the number of + internal matching function calls in a pcre_exec() execution. Further + details are given with pcre_exec() below. + + PCRE_CONFIG_MATCH_LIMIT_RECURSION + + The output is an integer that gives the default limit for the depth of + recursion when calling the internal matching function in a pcre_exec() + execution. Further details are given with pcre_exec() below. + + PCRE_CONFIG_STACKRECURSE + + The output is an integer that is set to one if internal recursion when + running pcre_exec() is implemented by recursive function calls that use + the stack to remember their state. This is the usual way that PCRE is + compiled. The output is zero if PCRE was compiled to use blocks of data + on the heap instead of recursive function calls. In this case, + pcre_stack_malloc and pcre_stack_free are called to manage memory + blocks on the heap, thus avoiding the use of the stack. + + +COMPILING A PATTERN + + pcre *pcre_compile(const char *pattern, int options, + const char **errptr, int *erroffset, + const unsigned char *tableptr); + + pcre *pcre_compile2(const char *pattern, int options, + int *errorcodeptr, + const char **errptr, int *erroffset, + const unsigned char *tableptr); + + Either of the functions pcre_compile() or pcre_compile2() can be called + to compile a pattern into an internal form. The only difference between + the two interfaces is that pcre_compile2() has an additional argument, + errorcodeptr, via which a numerical error code can be returned. + + The pattern is a C string terminated by a binary zero, and is passed in + the pattern argument. A pointer to a single block of memory that is + obtained via pcre_malloc is returned. This contains the compiled code + and related data. The pcre type is defined for the returned block; this + is a typedef for a structure whose contents are not externally defined. + It is up to the caller to free the memory (via pcre_free) when it is no + longer required. + + Although the compiled code of a PCRE regex is relocatable, that is, it + does not depend on memory location, the complete pcre data block is not + fully relocatable, because it may contain a copy of the tableptr argu- + ment, which is an address (see below). + + The options argument contains independent bits that affect the compila- + tion. It should be zero if no options are required. The available + options are described below. Some of them, in particular, those that + are compatible with Perl, can also be set and unset from within the + pattern (see the detailed description in the pcrepattern documenta- + tion). For these options, the contents of the options argument speci- + fies their initial settings at the start of compilation and execution. + The PCRE_ANCHORED and PCRE_NEWLINE_xxx options can be set at the time + of matching as well as at compile time. + + If errptr is NULL, pcre_compile() returns NULL immediately. Otherwise, + if compilation of a pattern fails, pcre_compile() returns NULL, and + sets the variable pointed to by errptr to point to a textual error mes- + sage. This is a static string that is part of the library. You must not + try to free it. The offset from the start of the pattern to the charac- + ter where the error was discovered is placed in the variable pointed to + by erroffset, which must not be NULL. If it is, an immediate error is + given. + + If pcre_compile2() is used instead of pcre_compile(), and the error- + codeptr argument is not NULL, a non-zero error code number is returned + via this argument in the event of an error. This is in addition to the + textual error message. Error codes and messages are listed below. + + If the final argument, tableptr, is NULL, PCRE uses a default set of + character tables that are built when PCRE is compiled, using the + default C locale. Otherwise, tableptr must be an address that is the + result of a call to pcre_maketables(). This value is stored with the + compiled pattern, and used again by pcre_exec(), unless another table + pointer is passed to it. For more discussion, see the section on locale + support below. + + This code fragment shows a typical straightforward call to pcre_com- + pile(): + + pcre *re; + const char *error; + int erroffset; + re = pcre_compile( + "^A.*Z", /* the pattern */ + 0, /* default options */ + &error, /* for error message */ + &erroffset, /* for error offset */ + NULL); /* use default character tables */ + + The following names for option bits are defined in the pcre.h header + file: + + PCRE_ANCHORED + + If this bit is set, the pattern is forced to be "anchored", that is, it + is constrained to match only at the first matching point in the string + that is being searched (the "subject string"). This effect can also be + achieved by appropriate constructs in the pattern itself, which is the + only way to do it in Perl. + + PCRE_AUTO_CALLOUT + + If this bit is set, pcre_compile() automatically inserts callout items, + all with number 255, before each pattern item. For discussion of the + callout facility, see the pcrecallout documentation. + + PCRE_CASELESS + + If this bit is set, letters in the pattern match both upper and lower + case letters. It is equivalent to Perl's /i option, and it can be + changed within a pattern by a (?i) option setting. In UTF-8 mode, PCRE + always understands the concept of case for characters whose values are + less than 128, so caseless matching is always possible. For characters + with higher values, the concept of case is supported if PCRE is com- + piled with Unicode property support, but not otherwise. If you want to + use caseless matching for characters 128 and above, you must ensure + that PCRE is compiled with Unicode property support as well as with + UTF-8 support. + + PCRE_DOLLAR_ENDONLY + + If this bit is set, a dollar metacharacter in the pattern matches only + at the end of the subject string. Without this option, a dollar also + matches immediately before a newline at the end of the string (but not + before any other newlines). The PCRE_DOLLAR_ENDONLY option is ignored + if PCRE_MULTILINE is set. There is no equivalent to this option in + Perl, and no way to set it within a pattern. + + PCRE_DOTALL + + If this bit is set, a dot metacharater in the pattern matches all char- + acters, including those that indicate newline. Without it, a dot does + not match when the current position is at a newline. This option is + equivalent to Perl's /s option, and it can be changed within a pattern + by a (?s) option setting. A negative class such as [^a] always matches + newlines, independent of the setting of this option. + + PCRE_DUPNAMES + + If this bit is set, names used to identify capturing subpatterns need + not be unique. This can be helpful for certain types of pattern when it + is known that only one instance of the named subpattern can ever be + matched. There are more details of named subpatterns below; see also + the pcrepattern documentation. + + PCRE_EXTENDED + + If this bit is set, whitespace data characters in the pattern are + totally ignored except when escaped or inside a character class. White- + space does not include the VT character (code 11). In addition, charac- + ters between an unescaped # outside a character class and the next new- + line, inclusive, are also ignored. This is equivalent to Perl's /x + option, and it can be changed within a pattern by a (?x) option set- + ting. + + This option makes it possible to include comments inside complicated + patterns. Note, however, that this applies only to data characters. + Whitespace characters may never appear within special character + sequences in a pattern, for example within the sequence (?( which + introduces a conditional subpattern. + + PCRE_EXTRA + + This option was invented in order to turn on additional functionality + of PCRE that is incompatible with Perl, but it is currently of very + little use. When set, any backslash in a pattern that is followed by a + letter that has no special meaning causes an error, thus reserving + these combinations for future expansion. By default, as in Perl, a + backslash followed by a letter with no special meaning is treated as a + literal. (Perl can, however, be persuaded to give a warning for this.) + There are at present no other features controlled by this option. It + can also be set by a (?X) option setting within a pattern. + + PCRE_FIRSTLINE + + If this option is set, an unanchored pattern is required to match + before or at the first newline in the subject string, though the + matched text may continue over the newline. + + PCRE_MULTILINE + + By default, PCRE treats the subject string as consisting of a single + line of characters (even if it actually contains newlines). The "start + of line" metacharacter (^) matches only at the start of the string, + while the "end of line" metacharacter ($) matches only at the end of + the string, or before a terminating newline (unless PCRE_DOLLAR_ENDONLY + is set). This is the same as Perl. + + When PCRE_MULTILINE it is set, the "start of line" and "end of line" + constructs match immediately following or immediately before internal + newlines in the subject string, respectively, as well as at the very + start and end. This is equivalent to Perl's /m option, and it can be + changed within a pattern by a (?m) option setting. If there are no new- + lines in a subject string, or no occurrences of ^ or $ in a pattern, + setting PCRE_MULTILINE has no effect. + + PCRE_NEWLINE_CR + PCRE_NEWLINE_LF + PCRE_NEWLINE_CRLF + + These options override the default newline definition that was chosen + when PCRE was built. Setting the first or the second specifies that a + newline is indicated by a single character (CR or LF, respectively). + Setting both of them specifies that a newline is indicated by the two- + character CRLF sequence. For convenience, PCRE_NEWLINE_CRLF is defined + to contain both bits. The only time that a line break is relevant when + compiling a pattern is if PCRE_EXTENDED is set, and an unescaped # out- + side a character class is encountered. This indicates a comment that + lasts until after the next newline. + + The newline option set at compile time becomes the default that is used + for pcre_exec() and pcre_dfa_exec(), but it can be overridden. + + PCRE_NO_AUTO_CAPTURE + + If this option is set, it disables the use of numbered capturing paren- + theses in the pattern. Any opening parenthesis that is not followed by + ? behaves as if it were followed by ?: but named parentheses can still + be used for capturing (and they acquire numbers in the usual way). + There is no equivalent of this option in Perl. + + PCRE_UNGREEDY + + This option inverts the "greediness" of the quantifiers so that they + are not greedy by default, but become greedy if followed by "?". It is + not compatible with Perl. It can also be set by a (?U) option setting + within the pattern. + + PCRE_UTF8 + + This option causes PCRE to regard both the pattern and the subject as + strings of UTF-8 characters instead of single-byte character strings. + However, it is available only when PCRE is built to include UTF-8 sup- + port. If not, the use of this option provokes an error. Details of how + this option changes the behaviour of PCRE are given in the section on + UTF-8 support in the main pcre page. + + PCRE_NO_UTF8_CHECK + + When PCRE_UTF8 is set, the validity of the pattern as a UTF-8 string is + automatically checked. If an invalid UTF-8 sequence of bytes is found, + pcre_compile() returns an error. If you already know that your pattern + is valid, and you want to skip this check for performance reasons, you + can set the PCRE_NO_UTF8_CHECK option. When it is set, the effect of + passing an invalid UTF-8 string as a pattern is undefined. It may cause + your program to crash. Note that this option can also be passed to + pcre_exec() and pcre_dfa_exec(), to suppress the UTF-8 validity check- + ing of subject strings. + + +COMPILATION ERROR CODES + + The following table lists the error codes than may be returned by + pcre_compile2(), along with the error messages that may be returned by + both compiling functions. + + 0 no error + 1 \ at end of pattern + 2 \c at end of pattern + 3 unrecognized character follows \ + 4 numbers out of order in {} quantifier + 5 number too big in {} quantifier + 6 missing terminating ] for character class + 7 invalid escape sequence in character class + 8 range out of order in character class + 9 nothing to repeat + 10 operand of unlimited repeat could match the empty string + 11 internal error: unexpected repeat + 12 unrecognized character after (? + 13 POSIX named classes are supported only within a class + 14 missing ) + 15 reference to non-existent subpattern + 16 erroffset passed as NULL + 17 unknown option bit(s) set + 18 missing ) after comment + 19 parentheses nested too deeply + 20 regular expression too large + 21 failed to get memory + 22 unmatched parentheses + 23 internal error: code overflow + 24 unrecognized character after (?< + 25 lookbehind assertion is not fixed length + 26 malformed number or name after (?( + 27 conditional group contains more than two branches + 28 assertion expected after (?( + 29 (?R or (?digits must be followed by ) + 30 unknown POSIX class name + 31 POSIX collating elements are not supported + 32 this version of PCRE is not compiled with PCRE_UTF8 support + 33 spare error + 34 character value in \x{...} sequence is too large + 35 invalid condition (?(0) + 36 \C not allowed in lookbehind assertion + 37 PCRE does not support \L, \l, \N, \U, or \u + 38 number after (?C is > 255 + 39 closing ) for (?C expected + 40 recursive call could loop indefinitely + 41 unrecognized character after (?P + 42 syntax error after (?P + 43 two named subpatterns have the same name + 44 invalid UTF-8 string + 45 support for \P, \p, and \X has not been compiled + 46 malformed \P or \p sequence + 47 unknown property name after \P or \p + 48 subpattern name is too long (maximum 32 characters) + 49 too many named subpatterns (maximum 10,000) + 50 repeated subpattern is too long + 51 octal value is greater than \377 (not in UTF-8 mode) + + +STUDYING A PATTERN + + pcre_extra *pcre_study(const pcre *code, int options + const char **errptr); + + If a compiled pattern is going to be used several times, it is worth + spending more time analyzing it in order to speed up the time taken for + matching. The function pcre_study() takes a pointer to a compiled pat- + tern as its first argument. If studying the pattern produces additional + information that will help speed up matching, pcre_study() returns a + pointer to a pcre_extra block, in which the study_data field points to + the results of the study. + + The returned value from pcre_study() can be passed directly to + pcre_exec(). However, a pcre_extra block also contains other fields + that can be set by the caller before the block is passed; these are + described below in the section on matching a pattern. + + If studying the pattern does not produce any additional information + pcre_study() returns NULL. In that circumstance, if the calling program + wants to pass any of the other fields to pcre_exec(), it must set up + its own pcre_extra block. + + The second argument of pcre_study() contains option bits. At present, + no options are defined, and this argument should always be zero. + + The third argument for pcre_study() is a pointer for an error message. + If studying succeeds (even if no data is returned), the variable it + points to is set to NULL. Otherwise it is set to point to a textual + error message. This is a static string that is part of the library. You + must not try to free it. You should test the error pointer for NULL + after calling pcre_study(), to be sure that it has run successfully. + + This is a typical call to pcre_study(): + + pcre_extra *pe; + pe = pcre_study( + re, /* result of pcre_compile() */ + 0, /* no options exist */ + &error); /* set to NULL or points to a message */ + + At present, studying a pattern is useful only for non-anchored patterns + that do not have a single fixed starting character. A bitmap of possi- + ble starting bytes is created. + + +LOCALE SUPPORT + + PCRE handles caseless matching, and determines whether characters are + letters digits, or whatever, by reference to a set of tables, indexed + by character value. When running in UTF-8 mode, this applies only to + characters with codes less than 128. Higher-valued codes never match + escapes such as \w or \d, but can be tested with \p if PCRE is built + with Unicode character property support. The use of locales with Uni- + code is discouraged. + + An internal set of tables is created in the default C locale when PCRE + is built. This is used when the final argument of pcre_compile() is + NULL, and is sufficient for many applications. An alternative set of + tables can, however, be supplied. These may be created in a different + locale from the default. As more and more applications change to using + Unicode, the need for this locale support is expected to die away. + + External tables are built by calling the pcre_maketables() function, + which has no arguments, in the relevant locale. The result can then be + passed to pcre_compile() or pcre_exec() as often as necessary. For + example, to build and use tables that are appropriate for the French + locale (where accented characters with values greater than 128 are + treated as letters), the following code could be used: + + setlocale(LC_CTYPE, "fr_FR"); + tables = pcre_maketables(); + re = pcre_compile(..., tables); + + When pcre_maketables() runs, the tables are built in memory that is + obtained via pcre_malloc. It is the caller's responsibility to ensure + that the memory containing the tables remains available for as long as + it is needed. + + The pointer that is passed to pcre_compile() is saved with the compiled + pattern, and the same tables are used via this pointer by pcre_study() + and normally also by pcre_exec(). Thus, by default, for any single pat- + tern, compilation, studying and matching all happen in the same locale, + but different patterns can be compiled in different locales. + + It is possible to pass a table pointer or NULL (indicating the use of + the internal tables) to pcre_exec(). Although not intended for this + purpose, this facility could be used to match a pattern in a different + locale from the one in which it was compiled. Passing table pointers at + run time is discussed below in the section on matching a pattern. + + +INFORMATION ABOUT A PATTERN + + int pcre_fullinfo(const pcre *code, const pcre_extra *extra, + int what, void *where); + + The pcre_fullinfo() function returns information about a compiled pat- + tern. It replaces the obsolete pcre_info() function, which is neverthe- + less retained for backwards compability (and is documented below). + + The first argument for pcre_fullinfo() is a pointer to the compiled + pattern. The second argument is the result of pcre_study(), or NULL if + the pattern was not studied. The third argument specifies which piece + of information is required, and the fourth argument is a pointer to a + variable to receive the data. The yield of the function is zero for + success, or one of the following negative numbers: + + PCRE_ERROR_NULL the argument code was NULL + the argument where was NULL + PCRE_ERROR_BADMAGIC the "magic number" was not found + PCRE_ERROR_BADOPTION the value of what was invalid + + The "magic number" is placed at the start of each compiled pattern as + an simple check against passing an arbitrary memory pointer. Here is a + typical call of pcre_fullinfo(), to obtain the length of the compiled + pattern: + + int rc; + size_t length; + rc = pcre_fullinfo( + re, /* result of pcre_compile() */ + pe, /* result of pcre_study(), or NULL */ + PCRE_INFO_SIZE, /* what is required */ + &length); /* where to put the data */ + + The possible values for the third argument are defined in pcre.h, and + are as follows: + + PCRE_INFO_BACKREFMAX + + Return the number of the highest back reference in the pattern. The + fourth argument should point to an int variable. Zero is returned if + there are no back references. + + PCRE_INFO_CAPTURECOUNT + + Return the number of capturing subpatterns in the pattern. The fourth + argument should point to an int variable. + + PCRE_INFO_DEFAULT_TABLES + + Return a pointer to the internal default character tables within PCRE. + The fourth argument should point to an unsigned char * variable. This + information call is provided for internal use by the pcre_study() func- + tion. External callers can cause PCRE to use its internal tables by + passing a NULL table pointer. + + PCRE_INFO_FIRSTBYTE + + Return information about the first byte of any matched string, for a + non-anchored pattern. The fourth argument should point to an int vari- + able. (This option used to be called PCRE_INFO_FIRSTCHAR; the old name + is still recognized for backwards compatibility.) + + If there is a fixed first byte, for example, from a pattern such as + (cat|cow|coyote). Otherwise, if either + + (a) the pattern was compiled with the PCRE_MULTILINE option, and every + branch starts with "^", or + + (b) every branch of the pattern starts with ".*" and PCRE_DOTALL is not + set (if it were set, the pattern would be anchored), + + -1 is returned, indicating that the pattern matches only at the start + of a subject string or after any newline within the string. Otherwise + -2 is returned. For anchored patterns, -2 is returned. + + PCRE_INFO_FIRSTTABLE + + If the pattern was studied, and this resulted in the construction of a + 256-bit table indicating a fixed set of bytes for the first byte in any + matching string, a pointer to the table is returned. Otherwise NULL is + returned. The fourth argument should point to an unsigned char * vari- + able. + + PCRE_INFO_LASTLITERAL + + Return the value of the rightmost literal byte that must exist in any + matched string, other than at its start, if such a byte has been + recorded. The fourth argument should point to an int variable. If there + is no such byte, -1 is returned. For anchored patterns, a last literal + byte is recorded only if it follows something of variable length. For + example, for the pattern /^a\d+z\d+/ the returned value is "z", but for + /^a\dz\d/ the returned value is -1. + + PCRE_INFO_NAMECOUNT + PCRE_INFO_NAMEENTRYSIZE + PCRE_INFO_NAMETABLE + + PCRE supports the use of named as well as numbered capturing parenthe- + ses. The names are just an additional way of identifying the parenthe- + ses, which still acquire numbers. Several convenience functions such as + pcre_get_named_substring() are provided for extracting captured sub- + strings by name. It is also possible to extract the data directly, by + first converting the name to a number in order to access the correct + pointers in the output vector (described with pcre_exec() below). To do + the conversion, you need to use the name-to-number map, which is + described by these three values. + + The map consists of a number of fixed-size entries. PCRE_INFO_NAMECOUNT + gives the number of entries, and PCRE_INFO_NAMEENTRYSIZE gives the size + of each entry; both of these return an int value. The entry size + depends on the length of the longest name. PCRE_INFO_NAMETABLE returns + a pointer to the first entry of the table (a pointer to char). The + first two bytes of each entry are the number of the capturing parenthe- + sis, most significant byte first. The rest of the entry is the corre- + sponding name, zero terminated. The names are in alphabetical order. + When PCRE_DUPNAMES is set, duplicate names are in order of their paren- + theses numbers. For example, consider the following pattern (assume + PCRE_EXTENDED is set, so white space - including newlines - is + ignored): + + (?P<date> (?P<year>(\d\d)?\d\d) - + (?P<month>\d\d) - (?P<day>\d\d) ) + + There are four named subpatterns, so the table has four entries, and + each entry in the table is eight bytes long. The table is as follows, + with non-printing bytes shows in hexadecimal, and undefined bytes shown + as ??: + + 00 01 d a t e 00 ?? + 00 05 d a y 00 ?? ?? + 00 04 m o n t h 00 + 00 02 y e a r 00 ?? + + When writing code to extract data from named subpatterns using the + name-to-number map, remember that the length of the entries is likely + to be different for each compiled pattern. + + PCRE_INFO_OPTIONS + + Return a copy of the options with which the pattern was compiled. The + fourth argument should point to an unsigned long int variable. These + option bits are those specified in the call to pcre_compile(), modified + by any top-level option settings within the pattern itself. + + A pattern is automatically anchored by PCRE if all of its top-level + alternatives begin with one of the following: + + ^ unless PCRE_MULTILINE is set + \A always + \G always + .* if PCRE_DOTALL is set and there are no back + references to the subpattern in which .* appears + + For such patterns, the PCRE_ANCHORED bit is set in the options returned + by pcre_fullinfo(). + + PCRE_INFO_SIZE + + Return the size of the compiled pattern, that is, the value that was + passed as the argument to pcre_malloc() when PCRE was getting memory in + which to place the compiled data. The fourth argument should point to a + size_t variable. + + PCRE_INFO_STUDYSIZE + + Return the size of the data block pointed to by the study_data field in + a pcre_extra block. That is, it is the value that was passed to + pcre_malloc() when PCRE was getting memory into which to place the data + created by pcre_study(). The fourth argument should point to a size_t + variable. + + +OBSOLETE INFO FUNCTION + + int pcre_info(const pcre *code, int *optptr, int *firstcharptr); + + The pcre_info() function is now obsolete because its interface is too + restrictive to return all the available data about a compiled pattern. + New programs should use pcre_fullinfo() instead. The yield of + pcre_info() is the number of capturing subpatterns, or one of the fol- + lowing negative numbers: + + PCRE_ERROR_NULL the argument code was NULL + PCRE_ERROR_BADMAGIC the "magic number" was not found + + If the optptr argument is not NULL, a copy of the options with which + the pattern was compiled is placed in the integer it points to (see + PCRE_INFO_OPTIONS above). + + If the pattern is not anchored and the firstcharptr argument is not + NULL, it is used to pass back information about the first character of + any matched string (see PCRE_INFO_FIRSTBYTE above). + + +REFERENCE COUNTS + + int pcre_refcount(pcre *code, int adjust); + + The pcre_refcount() function is used to maintain a reference count in + the data block that contains a compiled pattern. It is provided for the + benefit of applications that operate in an object-oriented manner, + where different parts of the application may be using the same compiled + pattern, but you want to free the block when they are all done. + + When a pattern is compiled, the reference count field is initialized to + zero. It is changed only by calling this function, whose action is to + add the adjust value (which may be positive or negative) to it. The + yield of the function is the new value. However, the value of the count + is constrained to lie between 0 and 65535, inclusive. If the new value + is outside these limits, it is forced to the appropriate limit value. + + Except when it is zero, the reference count is not correctly preserved + if a pattern is compiled on one host and then transferred to a host + whose byte-order is different. (This seems a highly unlikely scenario.) + + +MATCHING A PATTERN: THE TRADITIONAL FUNCTION + + int pcre_exec(const pcre *code, const pcre_extra *extra, + const char *subject, int length, int startoffset, + int options, int *ovector, int ovecsize); + + The function pcre_exec() is called to match a subject string against a + compiled pattern, which is passed in the code argument. If the pattern + has been studied, the result of the study should be passed in the extra + argument. This function is the main matching facility of the library, + and it operates in a Perl-like manner. For specialist use there is also + an alternative matching function, which is described below in the sec- + tion about the pcre_dfa_exec() function. + + In most applications, the pattern will have been compiled (and option- + ally studied) in the same process that calls pcre_exec(). However, it + is possible to save compiled patterns and study data, and then use them + later in different processes, possibly even on different hosts. For a + discussion about this, see the pcreprecompile documentation. + + Here is an example of a simple call to pcre_exec(): + + int rc; + int ovector[30]; + rc = pcre_exec( + re, /* result of pcre_compile() */ + NULL, /* we didn't study the pattern */ + "some string", /* the subject string */ + 11, /* the length of the subject string */ + 0, /* start at offset 0 in the subject */ + 0, /* default options */ + ovector, /* vector of integers for substring information */ + 30); /* number of elements (NOT size in bytes) */ + + Extra data for pcre_exec() + + If the extra argument is not NULL, it must point to a pcre_extra data + block. The pcre_study() function returns such a block (when it doesn't + return NULL), but you can also create one for yourself, and pass addi- + tional information in it. The pcre_extra block contains the following + fields (not necessarily in this order): + + unsigned long int flags; + void *study_data; + unsigned long int match_limit; + unsigned long int match_limit_recursion; + void *callout_data; + const unsigned char *tables; + + The flags field is a bitmap that specifies which of the other fields + are set. The flag bits are: + + PCRE_EXTRA_STUDY_DATA + PCRE_EXTRA_MATCH_LIMIT + PCRE_EXTRA_MATCH_LIMIT_RECURSION + PCRE_EXTRA_CALLOUT_DATA + PCRE_EXTRA_TABLES + + Other flag bits should be set to zero. The study_data field is set in + the pcre_extra block that is returned by pcre_study(), together with + the appropriate flag bit. You should not set this yourself, but you may + add to the block by setting the other fields and their corresponding + flag bits. + + The match_limit field provides a means of preventing PCRE from using up + a vast amount of resources when running patterns that are not going to + match, but which have a very large number of possibilities in their + search trees. The classic example is the use of nested unlimited + repeats. + + Internally, PCRE uses a function called match() which it calls repeat- + edly (sometimes recursively). The limit set by match_limit is imposed + on the number of times this function is called during a match, which + has the effect of limiting the amount of backtracking that can take + place. For patterns that are not anchored, the count restarts from zero + for each position in the subject string. + + The default value for the limit can be set when PCRE is built; the + default default is 10 million, which handles all but the most extreme + cases. You can override the default by suppling pcre_exec() with a + pcre_extra block in which match_limit is set, and + PCRE_EXTRA_MATCH_LIMIT is set in the flags field. If the limit is + exceeded, pcre_exec() returns PCRE_ERROR_MATCHLIMIT. + + The match_limit_recursion field is similar to match_limit, but instead + of limiting the total number of times that match() is called, it limits + the depth of recursion. The recursion depth is a smaller number than + the total number of calls, because not all calls to match() are recur- + sive. This limit is of use only if it is set smaller than match_limit. + + Limiting the recursion depth limits the amount of stack that can be + used, or, when PCRE has been compiled to use memory on the heap instead + of the stack, the amount of heap memory that can be used. + + The default value for match_limit_recursion can be set when PCRE is + built; the default default is the same value as the default for + match_limit. You can override the default by suppling pcre_exec() with + a pcre_extra block in which match_limit_recursion is set, and + PCRE_EXTRA_MATCH_LIMIT_RECURSION is set in the flags field. If the + limit is exceeded, pcre_exec() returns PCRE_ERROR_RECURSIONLIMIT. + + The pcre_callout field is used in conjunction with the "callout" fea- + ture, which is described in the pcrecallout documentation. + + The tables field is used to pass a character tables pointer to + pcre_exec(); this overrides the value that is stored with the compiled + pattern. A non-NULL value is stored with the compiled pattern only if + custom tables were supplied to pcre_compile() via its tableptr argu- + ment. If NULL is passed to pcre_exec() using this mechanism, it forces + PCRE's internal tables to be used. This facility is helpful when re- + using patterns that have been saved after compiling with an external + set of tables, because the external tables might be at a different + address when pcre_exec() is called. See the pcreprecompile documenta- + tion for a discussion of saving compiled patterns for later use. + + Option bits for pcre_exec() + + The unused bits of the options argument for pcre_exec() must be zero. + The only bits that may be set are PCRE_ANCHORED, PCRE_NEWLINE_xxx, + PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, PCRE_NO_UTF8_CHECK and + PCRE_PARTIAL. + + PCRE_ANCHORED + + The PCRE_ANCHORED option limits pcre_exec() to matching at the first + matching position. If a pattern was compiled with PCRE_ANCHORED, or + turned out to be anchored by virtue of its contents, it cannot be made + unachored at matching time. + + PCRE_NEWLINE_CR + PCRE_NEWLINE_LF + PCRE_NEWLINE_CRLF + + These options override the newline definition that was chosen or + defaulted when the pattern was compiled. For details, see the descrip- + tion pcre_compile() above. During matching, the newline choice affects + the behaviour of the dot, circumflex, and dollar metacharacters. + + PCRE_NOTBOL + + This option specifies that first character of the subject string is not + the beginning of a line, so the circumflex metacharacter should not + match before it. Setting this without PCRE_MULTILINE (at compile time) + causes circumflex never to match. This option affects only the behav- + iour of the circumflex metacharacter. It does not affect \A. + + PCRE_NOTEOL + + This option specifies that the end of the subject string is not the end + of a line, so the dollar metacharacter should not match it nor (except + in multiline mode) a newline immediately before it. Setting this with- + out PCRE_MULTILINE (at compile time) causes dollar never to match. This + option affects only the behaviour of the dollar metacharacter. It does + not affect \Z or \z. + + PCRE_NOTEMPTY + + An empty string is not considered to be a valid match if this option is + set. If there are alternatives in the pattern, they are tried. If all + the alternatives match the empty string, the entire match fails. For + example, if the pattern + + a?b? + + is applied to a string not beginning with "a" or "b", it matches the + empty string at the start of the subject. With PCRE_NOTEMPTY set, this + match is not valid, so PCRE searches further into the string for occur- + rences of "a" or "b". + + Perl has no direct equivalent of PCRE_NOTEMPTY, but it does make a spe- + cial case of a pattern match of the empty string within its split() + function, and when using the /g modifier. It is possible to emulate + Perl's behaviour after matching a null string by first trying the match + again at the same offset with PCRE_NOTEMPTY and PCRE_ANCHORED, and then + if that fails by advancing the starting offset (see below) and trying + an ordinary match again. There is some code that demonstrates how to do + this in the pcredemo.c sample program. + + PCRE_NO_UTF8_CHECK + + When PCRE_UTF8 is set at compile time, the validity of the subject as a + UTF-8 string is automatically checked when pcre_exec() is subsequently + called. The value of startoffset is also checked to ensure that it + points to the start of a UTF-8 character. If an invalid UTF-8 sequence + of bytes is found, pcre_exec() returns the error PCRE_ERROR_BADUTF8. If + startoffset contains an invalid value, PCRE_ERROR_BADUTF8_OFFSET is + returned. + + If you already know that your subject is valid, and you want to skip + these checks for performance reasons, you can set the + PCRE_NO_UTF8_CHECK option when calling pcre_exec(). You might want to + do this for the second and subsequent calls to pcre_exec() if you are + making repeated calls to find all the matches in a single subject + string. However, you should be sure that the value of startoffset + points to the start of a UTF-8 character. When PCRE_NO_UTF8_CHECK is + set, the effect of passing an invalid UTF-8 string as a subject, or a + value of startoffset that does not point to the start of a UTF-8 char- + acter, is undefined. Your program may crash. + + PCRE_PARTIAL + + This option turns on the partial matching feature. If the subject + string fails to match the pattern, but at some point during the match- + ing process the end of the subject was reached (that is, the subject + partially matches the pattern and the failure to match occurred only + because there were not enough subject characters), pcre_exec() returns + PCRE_ERROR_PARTIAL instead of PCRE_ERROR_NOMATCH. When PCRE_PARTIAL is + used, there are restrictions on what may appear in the pattern. These + are discussed in the pcrepartial documentation. + + The string to be matched by pcre_exec() + + The subject string is passed to pcre_exec() as a pointer in subject, a + length in length, and a starting byte offset in startoffset. In UTF-8 + mode, the byte offset must point to the start of a UTF-8 character. + Unlike the pattern string, the subject may contain binary zero bytes. + When the starting offset is zero, the search for a match starts at the + beginning of the subject, and this is by far the most common case. + + A non-zero starting offset is useful when searching for another match + in the same subject by calling pcre_exec() again after a previous suc- + cess. Setting startoffset differs from just passing over a shortened + string and setting PCRE_NOTBOL in the case of a pattern that begins + with any kind of lookbehind. For example, consider the pattern + + \Biss\B + + which finds occurrences of "iss" in the middle of words. (\B matches + only if the current position in the subject is not a word boundary.) + When applied to the string "Mississipi" the first call to pcre_exec() + finds the first occurrence. If pcre_exec() is called again with just + the remainder of the subject, namely "issipi", it does not match, + because \B is always false at the start of the subject, which is deemed + to be a word boundary. However, if pcre_exec() is passed the entire + string again, but with startoffset set to 4, it finds the second occur- + rence of "iss" because it is able to look behind the starting point to + discover that it is preceded by a letter. + + If a non-zero starting offset is passed when the pattern is anchored, + one attempt to match at the given offset is made. This can only succeed + if the pattern does not require the match to be at the start of the + subject. + + How pcre_exec() returns captured substrings + + In general, a pattern matches a certain portion of the subject, and in + addition, further substrings from the subject may be picked out by + parts of the pattern. Following the usage in Jeffrey Friedl's book, + this is called "capturing" in what follows, and the phrase "capturing + subpattern" is used for a fragment of a pattern that picks out a sub- + string. PCRE supports several other kinds of parenthesized subpattern + that do not cause substrings to be captured. + + Captured substrings are returned to the caller via a vector of integer + offsets whose address is passed in ovector. The number of elements in + the vector is passed in ovecsize, which must be a non-negative number. + Note: this argument is NOT the size of ovector in bytes. + + The first two-thirds of the vector is used to pass back captured sub- + strings, each substring using a pair of integers. The remaining third + of the vector is used as workspace by pcre_exec() while matching cap- + turing subpatterns, and is not available for passing back information. + The length passed in ovecsize should always be a multiple of three. If + it is not, it is rounded down. + + When a match is successful, information about captured substrings is + returned in pairs of integers, starting at the beginning of ovector, + and continuing up to two-thirds of its length at the most. The first + element of a pair is set to the offset of the first character in a sub- + string, and the second is set to the offset of the first character + after the end of a substring. The first pair, ovector[0] and ovec- + tor[1], identify the portion of the subject string matched by the + entire pattern. The next pair is used for the first capturing subpat- + tern, and so on. The value returned by pcre_exec() is one more than the + highest numbered pair that has been set. For example, if two substrings + have been captured, the returned value is 3. If there are no capturing + subpatterns, the return value from a successful match is 1, indicating + that just the first pair of offsets has been set. + + If a capturing subpattern is matched repeatedly, it is the last portion + of the string that it matched that is returned. + + If the vector is too small to hold all the captured substring offsets, + it is used as far as possible (up to two-thirds of its length), and the + function returns a value of zero. In particular, if the substring off- + sets are not of interest, pcre_exec() may be called with ovector passed + as NULL and ovecsize as zero. However, if the pattern contains back + references and the ovector is not big enough to remember the related + substrings, PCRE has to get additional memory for use during matching. + Thus it is usually advisable to supply an ovector. + + The pcre_info() function can be used to find out how many capturing + subpatterns there are in a compiled pattern. The smallest size for + ovector that will allow for n captured substrings, in addition to the + offsets of the substring matched by the whole pattern, is (n+1)*3. + + It is possible for capturing subpattern number n+1 to match some part + of the subject when subpattern n has not been used at all. For example, + if the string "abc" is matched against the pattern (a|(z))(bc) the + return from the function is 4, and subpatterns 1 and 3 are matched, but + 2 is not. When this happens, both values in the offset pairs corre- + sponding to unused subpatterns are set to -1. + + Offset values that correspond to unused subpatterns at the end of the + expression are also set to -1. For example, if the string "abc" is + matched against the pattern (abc)(x(yz)?)? subpatterns 2 and 3 are not + matched. The return from the function is 2, because the highest used + capturing subpattern number is 1. However, you can refer to the offsets + for the second and third capturing subpatterns if you wish (assuming + the vector is large enough, of course). + + Some convenience functions are provided for extracting the captured + substrings as separate strings. These are described below. + + Error return values from pcre_exec() + + If pcre_exec() fails, it returns a negative number. The following are + defined in the header file: + + PCRE_ERROR_NOMATCH (-1) + + The subject string did not match the pattern. + + PCRE_ERROR_NULL (-2) + + Either code or subject was passed as NULL, or ovector was NULL and + ovecsize was not zero. + + PCRE_ERROR_BADOPTION (-3) + + An unrecognized bit was set in the options argument. + + PCRE_ERROR_BADMAGIC (-4) + + PCRE stores a 4-byte "magic number" at the start of the compiled code, + to catch the case when it is passed a junk pointer and to detect when a + pattern that was compiled in an environment of one endianness is run in + an environment with the other endianness. This is the error that PCRE + gives when the magic number is not present. + + PCRE_ERROR_UNKNOWN_NODE (-5) + + While running the pattern match, an unknown item was encountered in the + compiled pattern. This error could be caused by a bug in PCRE or by + overwriting of the compiled pattern. + + PCRE_ERROR_NOMEMORY (-6) + + If a pattern contains back references, but the ovector that is passed + to pcre_exec() is not big enough to remember the referenced substrings, + PCRE gets a block of memory at the start of matching to use for this + purpose. If the call via pcre_malloc() fails, this error is given. The + memory is automatically freed at the end of matching. + + PCRE_ERROR_NOSUBSTRING (-7) + + This error is used by the pcre_copy_substring(), pcre_get_substring(), + and pcre_get_substring_list() functions (see below). It is never + returned by pcre_exec(). + + PCRE_ERROR_MATCHLIMIT (-8) + + The backtracking limit, as specified by the match_limit field in a + pcre_extra structure (or defaulted) was reached. See the description + above. + + PCRE_ERROR_RECURSIONLIMIT (-21) + + The internal recursion limit, as specified by the match_limit_recursion + field in a pcre_extra structure (or defaulted) was reached. See the + description above. + + PCRE_ERROR_CALLOUT (-9) + + This error is never generated by pcre_exec() itself. It is provided for + use by callout functions that want to yield a distinctive error code. + See the pcrecallout documentation for details. + + PCRE_ERROR_BADUTF8 (-10) + + A string that contains an invalid UTF-8 byte sequence was passed as a + subject. + + PCRE_ERROR_BADUTF8_OFFSET (-11) + + The UTF-8 byte sequence that was passed as a subject was valid, but the + value of startoffset did not point to the beginning of a UTF-8 charac- + ter. + + PCRE_ERROR_PARTIAL (-12) + + The subject string did not match, but it did match partially. See the + pcrepartial documentation for details of partial matching. + + PCRE_ERROR_BADPARTIAL (-13) + + The PCRE_PARTIAL option was used with a compiled pattern containing + items that are not supported for partial matching. See the pcrepartial + documentation for details of partial matching. + + PCRE_ERROR_INTERNAL (-14) + + An unexpected internal error has occurred. This error could be caused + by a bug in PCRE or by overwriting of the compiled pattern. + + PCRE_ERROR_BADCOUNT (-15) + + This error is given if the value of the ovecsize argument is negative. + + +EXTRACTING CAPTURED SUBSTRINGS BY NUMBER + + int pcre_copy_substring(const char *subject, int *ovector, + int stringcount, int stringnumber, char *buffer, + int buffersize); + + int pcre_get_substring(const char *subject, int *ovector, + int stringcount, int stringnumber, + const char **stringptr); + + int pcre_get_substring_list(const char *subject, + int *ovector, int stringcount, const char ***listptr); + + Captured substrings can be accessed directly by using the offsets + returned by pcre_exec() in ovector. For convenience, the functions + pcre_copy_substring(), pcre_get_substring(), and pcre_get_sub- + string_list() are provided for extracting captured substrings as new, + separate, zero-terminated strings. These functions identify substrings + by number. The next section describes functions for extracting named + substrings. + + A substring that contains a binary zero is correctly extracted and has + a further zero added on the end, but the result is not, of course, a C + string. However, you can process such a string by referring to the + length that is returned by pcre_copy_substring() and pcre_get_sub- + string(). Unfortunately, the interface to pcre_get_substring_list() is + not adequate for handling strings containing binary zeros, because the + end of the final string is not independently indicated. + + The first three arguments are the same for all three of these func- + tions: subject is the subject string that has just been successfully + matched, ovector is a pointer to the vector of integer offsets that was + passed to pcre_exec(), and stringcount is the number of substrings that + were captured by the match, including the substring that matched the + entire regular expression. This is the value returned by pcre_exec() if + it is greater than zero. If pcre_exec() returned zero, indicating that + it ran out of space in ovector, the value passed as stringcount should + be the number of elements in the vector divided by three. + + The functions pcre_copy_substring() and pcre_get_substring() extract a + single substring, whose number is given as stringnumber. A value of + zero extracts the substring that matched the entire pattern, whereas + higher values extract the captured substrings. For pcre_copy_sub- + string(), the string is placed in buffer, whose length is given by + buffersize, while for pcre_get_substring() a new block of memory is + obtained via pcre_malloc, and its address is returned via stringptr. + The yield of the function is the length of the string, not including + the terminating zero, or one of + + PCRE_ERROR_NOMEMORY (-6) + + The buffer was too small for pcre_copy_substring(), or the attempt to + get memory failed for pcre_get_substring(). + + PCRE_ERROR_NOSUBSTRING (-7) + + There is no substring whose number is stringnumber. + + The pcre_get_substring_list() function extracts all available sub- + strings and builds a list of pointers to them. All this is done in a + single block of memory that is obtained via pcre_malloc. The address of + the memory block is returned via listptr, which is also the start of + the list of string pointers. The end of the list is marked by a NULL + pointer. The yield of the function is zero if all went well, or + + PCRE_ERROR_NOMEMORY (-6) + + if the attempt to get the memory block failed. + + When any of these functions encounter a substring that is unset, which + can happen when capturing subpattern number n+1 matches some part of + the subject, but subpattern n has not been used at all, they return an + empty string. This can be distinguished from a genuine zero-length sub- + string by inspecting the appropriate offset in ovector, which is nega- + tive for unset substrings. + + The two convenience functions pcre_free_substring() and pcre_free_sub- + string_list() can be used to free the memory returned by a previous + call of pcre_get_substring() or pcre_get_substring_list(), respec- + tively. They do nothing more than call the function pointed to by + pcre_free, which of course could be called directly from a C program. + However, PCRE is used in some situations where it is linked via a spe- + cial interface to another programming language that cannot use + pcre_free directly; it is for these cases that the functions are pro- + vided. + + +EXTRACTING CAPTURED SUBSTRINGS BY NAME + + int pcre_get_stringnumber(const pcre *code, + const char *name); + + int pcre_copy_named_substring(const pcre *code, + const char *subject, int *ovector, + int stringcount, const char *stringname, + char *buffer, int buffersize); + + int pcre_get_named_substring(const pcre *code, + const char *subject, int *ovector, + int stringcount, const char *stringname, + const char **stringptr); + + To extract a substring by name, you first have to find associated num- + ber. For example, for this pattern + + (a+)b(?P<xxx>\d+)... + + the number of the subpattern called "xxx" is 2. If the name is known to + be unique (PCRE_DUPNAMES was not set), you can find the number from the + name by calling pcre_get_stringnumber(). The first argument is the com- + piled pattern, and the second is the name. The yield of the function is + the subpattern number, or PCRE_ERROR_NOSUBSTRING (-7) if there is no + subpattern of that name. + + Given the number, you can extract the substring directly, or use one of + the functions described in the previous section. For convenience, there + are also two functions that do the whole job. + + Most of the arguments of pcre_copy_named_substring() and + pcre_get_named_substring() are the same as those for the similarly + named functions that extract by number. As these are described in the + previous section, they are not re-described here. There are just two + differences: + + First, instead of a substring number, a substring name is given. Sec- + ond, there is an extra argument, given at the start, which is a pointer + to the compiled pattern. This is needed in order to gain access to the + name-to-number translation table. + + These functions call pcre_get_stringnumber(), and if it succeeds, they + then call pcre_copy_substring() or pcre_get_substring(), as appropri- + ate. + + +DUPLICATE SUBPATTERN NAMES + + int pcre_get_stringtable_entries(const pcre *code, + const char *name, char **first, char **last); + + When a pattern is compiled with the PCRE_DUPNAMES option, names for + subpatterns are not required to be unique. Normally, patterns with + duplicate names are such that in any one match, only one of the named + subpatterns participates. An example is shown in the pcrepattern docu- + mentation. When duplicates are present, pcre_copy_named_substring() and + pcre_get_named_substring() return the first substring corresponding to + the given name that is set. If none are set, an empty string is + returned. The pcre_get_stringnumber() function returns one of the num- + bers that are associated with the name, but it is not defined which it + is. + + If you want to get full details of all captured substrings for a given + name, you must use the pcre_get_stringtable_entries() function. The + first argument is the compiled pattern, and the second is the name. The + third and fourth are pointers to variables which are updated by the + function. After it has run, they point to the first and last entries in + the name-to-number table for the given name. The function itself + returns the length of each entry, or PCRE_ERROR_NOSUBSTRING if there + are none. The format of the table is described above in the section + entitled Information about a pattern. Given all the relevant entries + for the name, you can extract each of their numbers, and hence the cap- + tured data, if any. + + +FINDING ALL POSSIBLE MATCHES + + The traditional matching function uses a similar algorithm to Perl, + which stops when it finds the first match, starting at a given point in + the subject. If you want to find all possible matches, or the longest + possible match, consider using the alternative matching function (see + below) instead. If you cannot use the alternative function, but still + need to find all possible matches, you can kludge it up by making use + of the callout facility, which is described in the pcrecallout documen- + tation. + + What you have to do is to insert a callout right at the end of the pat- + tern. When your callout function is called, extract and save the cur- + rent matched substring. Then return 1, which forces pcre_exec() to + backtrack and try other alternatives. Ultimately, when it runs out of + matches, pcre_exec() will yield PCRE_ERROR_NOMATCH. + + +MATCHING A PATTERN: THE ALTERNATIVE FUNCTION + + int pcre_dfa_exec(const pcre *code, const pcre_extra *extra, + const char *subject, int length, int startoffset, + int options, int *ovector, int ovecsize, + int *workspace, int wscount); + + The function pcre_dfa_exec() is called to match a subject string + against a compiled pattern, using a "DFA" matching algorithm. This has + different characteristics to the normal algorithm, and is not compati- + ble with Perl. Some of the features of PCRE patterns are not supported. + Nevertheless, there are times when this kind of matching can be useful. + For a discussion of the two matching algorithms, see the pcrematching + documentation. + + The arguments for the pcre_dfa_exec() function are the same as for + pcre_exec(), plus two extras. The ovector argument is used in a differ- + ent way, and this is described below. The other common arguments are + used in the same way as for pcre_exec(), so their description is not + repeated here. + + The two additional arguments provide workspace for the function. The + workspace vector should contain at least 20 elements. It is used for + keeping track of multiple paths through the pattern tree. More + workspace will be needed for patterns and subjects where there are a + lot of potential matches. + + Here is an example of a simple call to pcre_dfa_exec(): + + int rc; + int ovector[10]; + int wspace[20]; + rc = pcre_dfa_exec( + re, /* result of pcre_compile() */ + NULL, /* we didn't study the pattern */ + "some string", /* the subject string */ + 11, /* the length of the subject string */ + 0, /* start at offset 0 in the subject */ + 0, /* default options */ + ovector, /* vector of integers for substring information */ + 10, /* number of elements (NOT size in bytes) */ + wspace, /* working space vector */ + 20); /* number of elements (NOT size in bytes) */ + + Option bits for pcre_dfa_exec() + + The unused bits of the options argument for pcre_dfa_exec() must be + zero. The only bits that may be set are PCRE_ANCHORED, PCRE_NEW- + LINE_xxx, PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, PCRE_NO_UTF8_CHECK, + PCRE_PARTIAL, PCRE_DFA_SHORTEST, and PCRE_DFA_RESTART. All but the last + three of these are the same as for pcre_exec(), so their description is + not repeated here. + + PCRE_PARTIAL + + This has the same general effect as it does for pcre_exec(), but the + details are slightly different. When PCRE_PARTIAL is set for + pcre_dfa_exec(), the return code PCRE_ERROR_NOMATCH is converted into + PCRE_ERROR_PARTIAL if the end of the subject is reached, there have + been no complete matches, but there is still at least one matching pos- + sibility. The portion of the string that provided the partial match is + set as the first matching string. + + PCRE_DFA_SHORTEST + + Setting the PCRE_DFA_SHORTEST option causes the matching algorithm to + stop as soon as it has found one match. Because of the way the DFA + algorithm works, this is necessarily the shortest possible match at the + first possible matching point in the subject string. + + PCRE_DFA_RESTART + + When pcre_dfa_exec() is called with the PCRE_PARTIAL option, and + returns a partial match, it is possible to call it again, with addi- + tional subject characters, and have it continue with the same match. + The PCRE_DFA_RESTART option requests this action; when it is set, the + workspace and wscount options must reference the same vector as before + because data about the match so far is left in them after a partial + match. There is more discussion of this facility in the pcrepartial + documentation. + + Successful returns from pcre_dfa_exec() + + When pcre_dfa_exec() succeeds, it may have matched more than one sub- + string in the subject. Note, however, that all the matches from one run + of the function start at the same point in the subject. The shorter + matches are all initial substrings of the longer matches. For example, + if the pattern + + <.*> + + is matched against the string + + This is <something> <something else> <something further> no more + + the three matched strings are + + <something> + <something> <something else> + <something> <something else> <something further> + + On success, the yield of the function is a number greater than zero, + which is the number of matched substrings. The substrings themselves + are returned in ovector. Each string uses two elements; the first is + the offset to the start, and the second is the offset to the end. All + the strings have the same start offset. (Space could have been saved by + giving this only once, but it was decided to retain some compatibility + with the way pcre_exec() returns data, even though the meaning of the + strings is different.) + + The strings are returned in reverse order of length; that is, the long- + est matching string is given first. If there were too many matches to + fit into ovector, the yield of the function is zero, and the vector is + filled with the longest matches. + + Error returns from pcre_dfa_exec() + + The pcre_dfa_exec() function returns a negative number when it fails. + Many of the errors are the same as for pcre_exec(), and these are + described above. There are in addition the following errors that are + specific to pcre_dfa_exec(): + + PCRE_ERROR_DFA_UITEM (-16) + + This return is given if pcre_dfa_exec() encounters an item in the pat- + tern that it does not support, for instance, the use of \C or a back + reference. + + PCRE_ERROR_DFA_UCOND (-17) + + This return is given if pcre_dfa_exec() encounters a condition item in + a pattern that uses a back reference for the condition. This is not + supported. + + PCRE_ERROR_DFA_UMLIMIT (-18) + + This return is given if pcre_dfa_exec() is called with an extra block + that contains a setting of the match_limit field. This is not supported + (it is meaningless). + + PCRE_ERROR_DFA_WSSIZE (-19) + + This return is given if pcre_dfa_exec() runs out of space in the + workspace vector. + + PCRE_ERROR_DFA_RECURSE (-20) + + When a recursive subpattern is processed, the matching function calls + itself recursively, using private vectors for ovector and workspace. + This error is given if the output vector is not large enough. This + should be extremely rare, as a vector of size 1000 is used. + +Last updated: 08 June 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + +PCRECALLOUT(3) PCRECALLOUT(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +PCRE CALLOUTS + + int (*pcre_callout)(pcre_callout_block *); + + PCRE provides a feature called "callout", which is a means of temporar- + ily passing control to the caller of PCRE in the middle of pattern + matching. The caller of PCRE provides an external function by putting + its entry point in the global variable pcre_callout. By default, this + variable contains NULL, which disables all calling out. + + Within a regular expression, (?C) indicates the points at which the + external function is to be called. Different callout points can be + identified by putting a number less than 256 after the letter C. The + default value is zero. For example, this pattern has two callout + points: + + (?C1)eabc(?C2)def + + If the PCRE_AUTO_CALLOUT option bit is set when pcre_compile() is + called, PCRE automatically inserts callouts, all with number 255, + before each item in the pattern. For example, if PCRE_AUTO_CALLOUT is + used with the pattern + + A(\d{2}|--) + + it is processed as if it were + + (?C255)A(?C255)((?C255)\d{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255) + + Notice that there is a callout before and after each parenthesis and + alternation bar. Automatic callouts can be used for tracking the + progress of pattern matching. The pcretest command has an option that + sets automatic callouts; when it is used, the output indicates how the + pattern is matched. This is useful information when you are trying to + optimize the performance of a particular pattern. + + +MISSING CALLOUTS + + You should be aware that, because of optimizations in the way PCRE + matches patterns, callouts sometimes do not happen. For example, if the + pattern is + + ab(?C4)cd + + PCRE knows that any matching string must contain the letter "d". If the + subject string is "abyz", the lack of "d" means that matching doesn't + ever start, and the callout is never reached. However, with "abyd", + though the result is still no match, the callout is obeyed. + + +THE CALLOUT INTERFACE + + During matching, when PCRE reaches a callout point, the external func- + tion defined by pcre_callout is called (if it is set). This applies to + both the pcre_exec() and the pcre_dfa_exec() matching functions. The + only argument to the callout function is a pointer to a pcre_callout + block. This structure contains the following fields: + + int version; + int callout_number; + int *offset_vector; + const char *subject; + int subject_length; + int start_match; + int current_position; + int capture_top; + int capture_last; + void *callout_data; + int pattern_position; + int next_item_length; + + The version field is an integer containing the version number of the + block format. The initial version was 0; the current version is 1. The + version number will change again in future if additional fields are + added, but the intention is never to remove any of the existing fields. + + The callout_number field contains the number of the callout, as com- + piled into the pattern (that is, the number after ?C for manual call- + outs, and 255 for automatically generated callouts). + + The offset_vector field is a pointer to the vector of offsets that was + passed by the caller to pcre_exec() or pcre_dfa_exec(). When + pcre_exec() is used, the contents can be inspected in order to extract + substrings that have been matched so far, in the same way as for + extracting substrings after a match has completed. For pcre_dfa_exec() + this field is not useful. + + The subject and subject_length fields contain copies of the values that + were passed to pcre_exec(). + + The start_match field contains the offset within the subject at which + the current match attempt started. If the pattern is not anchored, the + callout function may be called several times from the same point in the + pattern for different starting points in the subject. + + The current_position field contains the offset within the subject of + the current match pointer. + + When the pcre_exec() function is used, the capture_top field contains + one more than the number of the highest numbered captured substring so + far. If no substrings have been captured, the value of capture_top is + one. This is always the case when pcre_dfa_exec() is used, because it + does not support captured substrings. + + The capture_last field contains the number of the most recently cap- + tured substring. If no substrings have been captured, its value is -1. + This is always the case when pcre_dfa_exec() is used. + + The callout_data field contains a value that is passed to pcre_exec() + or pcre_dfa_exec() specifically so that it can be passed back in call- + outs. It is passed in the pcre_callout field of the pcre_extra data + structure. If no such data was passed, the value of callout_data in a + pcre_callout block is NULL. There is a description of the pcre_extra + structure in the pcreapi documentation. + + The pattern_position field is present from version 1 of the pcre_call- + out structure. It contains the offset to the next item to be matched in + the pattern string. + + The next_item_length field is present from version 1 of the pcre_call- + out structure. It contains the length of the next item to be matched in + the pattern string. When the callout immediately precedes an alterna- + tion bar, a closing parenthesis, or the end of the pattern, the length + is zero. When the callout precedes an opening parenthesis, the length + is that of the entire subpattern. + + The pattern_position and next_item_length fields are intended to help + in distinguishing between different automatic callouts, which all have + the same callout number. However, they are set for all callouts. + + +RETURN VALUES + + The external callout function returns an integer to PCRE. If the value + is zero, matching proceeds as normal. If the value is greater than + zero, matching fails at the current point, but the testing of other + matching possibilities goes ahead, just as if a lookahead assertion had + failed. If the value is less than zero, the match is abandoned, and + pcre_exec() (or pcre_dfa_exec()) returns the negative value. + + Negative values should normally be chosen from the set of + PCRE_ERROR_xxx values. In particular, PCRE_ERROR_NOMATCH forces a stan- + dard "no match" failure. The error number PCRE_ERROR_CALLOUT is + reserved for use by callout functions; it will never be used by PCRE + itself. + +Last updated: 28 February 2005 +Copyright (c) 1997-2005 University of Cambridge. +------------------------------------------------------------------------------ + + +PCRECOMPAT(3) PCRECOMPAT(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +DIFFERENCES BETWEEN PCRE AND PERL + + This document describes the differences in the ways that PCRE and Perl + handle regular expressions. The differences described here are with + respect to Perl 5.8. + + 1. PCRE has only a subset of Perl's UTF-8 and Unicode support. Details + of what it does have are given in the section on UTF-8 support in the + main pcre page. + + 2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl + permits them, but they do not mean what you might think. For example, + (?!a){3} does not assert that the next three characters are not "a". It + just asserts that the next character is not "a" three times. + + 3. Capturing subpatterns that occur inside negative lookahead asser- + tions are counted, but their entries in the offsets vector are never + set. Perl sets its numerical variables from any such patterns that are + matched before the assertion fails to match something (thereby succeed- + ing), but only if the negative lookahead assertion contains just one + branch. + + 4. Though binary zero characters are supported in the subject string, + they are not allowed in a pattern string because it is passed as a nor- + mal C string, terminated by zero. The escape sequence \0 can be used in + the pattern to represent a binary zero. + + 5. The following Perl escape sequences are not supported: \l, \u, \L, + \U, and \N. In fact these are implemented by Perl's general string-han- + dling and are not part of its pattern matching engine. If any of these + are encountered by PCRE, an error is generated. + + 6. The Perl escape sequences \p, \P, and \X are supported only if PCRE + is built with Unicode character property support. The properties that + can be tested with \p and \P are limited to the general category prop- + erties such as Lu and Nd, script names such as Greek or Han, and the + derived properties Any and L&. + + 7. PCRE does support the \Q...\E escape for quoting substrings. Charac- + ters in between are treated as literals. This is slightly different + from Perl in that $ and @ are also handled as literals inside the + quotes. In Perl, they cause variable interpolation (but of course PCRE + does not have variables). Note the following examples: + + Pattern PCRE matches Perl matches + + \Qabc$xyz\E abc$xyz abc followed by the + contents of $xyz + \Qabc\$xyz\E abc\$xyz abc\$xyz + \Qabc\E\$\Qxyz\E abc$xyz abc$xyz + + The \Q...\E sequence is recognized both inside and outside character + classes. + + 8. Fairly obviously, PCRE does not support the (?{code}) and (?p{code}) + constructions. However, there is support for recursive patterns using + the non-Perl items (?R), (?number), and (?P>name). Also, the PCRE + "callout" feature allows an external function to be called during pat- + tern matching. See the pcrecallout documentation for details. + + 9. There are some differences that are concerned with the settings of + captured strings when part of a pattern is repeated. For example, + matching "aba" against the pattern /^(a(b)?)+$/ in Perl leaves $2 + unset, but in PCRE it is set to "b". + + 10. PCRE provides some extensions to the Perl regular expression facil- + ities: + + (a) Although lookbehind assertions must match fixed length strings, + each alternative branch of a lookbehind assertion can match a different + length of string. Perl requires them all to have the same length. + + (b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not set, the $ + meta-character matches only at the very end of the string. + + (c) If PCRE_EXTRA is set, a backslash followed by a letter with no spe- + cial meaning is faulted. Otherwise, like Perl, the backslash is + ignored. (Perl can be made to issue a warning.) + + (d) If PCRE_UNGREEDY is set, the greediness of the repetition quanti- + fiers is inverted, that is, by default they are not greedy, but if fol- + lowed by a question mark they are. + + (e) PCRE_ANCHORED can be used at matching time to force a pattern to be + tried only at the first matching position in the subject string. + + (f) The PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, and PCRE_NO_AUTO_CAP- + TURE options for pcre_exec() have no Perl equivalents. + + (g) The (?R), (?number), and (?P>name) constructs allows for recursive + pattern matching (Perl can do this using the (?p{code}) construct, + which PCRE cannot support.) + + (h) PCRE supports named capturing substrings, using the Python syntax. + + (i) PCRE supports the possessive quantifier "++" syntax, taken from + Sun's Java package. + + (j) The (R) condition, for testing recursion, is a PCRE extension. + + (k) The callout facility is PCRE-specific. + + (l) The partial matching facility is PCRE-specific. + + (m) Patterns compiled by PCRE can be saved and re-used at a later time, + even on different hosts that have the other endianness. + + (n) The alternative matching function (pcre_dfa_exec()) matches in a + different way and is not Perl-compatible. + +Last updated: 06 June 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + +PCREPATTERN(3) PCREPATTERN(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +PCRE REGULAR EXPRESSION DETAILS + + The syntax and semantics of the regular expressions supported by PCRE + are described below. Regular expressions are also described in the Perl + documentation and in a number of books, some of which have copious + examples. Jeffrey Friedl's "Mastering Regular Expressions", published + by O'Reilly, covers regular expressions in great detail. This descrip- + tion of PCRE's regular expressions is intended as reference material. + + The original operation of PCRE was on strings of one-byte characters. + However, there is now also support for UTF-8 character strings. To use + this, you must build PCRE to include UTF-8 support, and then call + pcre_compile() with the PCRE_UTF8 option. How this affects pattern + matching is mentioned in several places below. There is also a summary + of UTF-8 features in the section on UTF-8 support in the main pcre + page. + + The remainder of this document discusses the patterns that are sup- + ported by PCRE when its main matching function, pcre_exec(), is used. + From release 6.0, PCRE offers a second matching function, + pcre_dfa_exec(), which matches using a different algorithm that is not + Perl-compatible. The advantages and disadvantages of the alternative + function, and how it differs from the normal function, are discussed in + the pcrematching page. + + A regular expression is a pattern that is matched against a subject + string from left to right. Most characters stand for themselves in a + pattern, and match the corresponding characters in the subject. As a + trivial example, the pattern + + The quick brown fox + + matches a portion of a subject string that is identical to itself. When + caseless matching is specified (the PCRE_CASELESS option), letters are + matched independently of case. In UTF-8 mode, PCRE always understands + the concept of case for characters whose values are less than 128, so + caseless matching is always possible. For characters with higher val- + ues, the concept of case is supported if PCRE is compiled with Unicode + property support, but not otherwise. If you want to use caseless + matching for characters 128 and above, you must ensure that PCRE is + compiled with Unicode property support as well as with UTF-8 support. + + The power of regular expressions comes from the ability to include + alternatives and repetitions in the pattern. These are encoded in the + pattern by the use of metacharacters, which do not stand for themselves + but instead are interpreted in some special way. + + There are two different sets of metacharacters: those that are recog- + nized anywhere in the pattern except within square brackets, and those + that are recognized in square brackets. Outside square brackets, the + metacharacters are as follows: + + \ general escape character with several uses + ^ assert start of string (or line, in multiline mode) + $ assert end of string (or line, in multiline mode) + . match any character except newline (by default) + [ start character class definition + | start of alternative branch + ( start subpattern + ) end subpattern + ? extends the meaning of ( + also 0 or 1 quantifier + also quantifier minimizer + * 0 or more quantifier + + 1 or more quantifier + also "possessive quantifier" + { start min/max quantifier + + Part of a pattern that is in square brackets is called a "character + class". In a character class the only metacharacters are: + + \ general escape character + ^ negate the class, but only if the first character + - indicates character range + [ POSIX character class (only if followed by POSIX + syntax) + ] terminates the character class + + The following sections describe the use of each of the metacharacters. + + +BACKSLASH + + The backslash character has several uses. Firstly, if it is followed by + a non-alphanumeric character, it takes away any special meaning that + character may have. This use of backslash as an escape character + applies both inside and outside character classes. + + For example, if you want to match a * character, you write \* in the + pattern. This escaping action applies whether or not the following + character would otherwise be interpreted as a metacharacter, so it is + always safe to precede a non-alphanumeric with backslash to specify + that it stands for itself. In particular, if you want to match a back- + slash, you write \\. + + If a pattern is compiled with the PCRE_EXTENDED option, whitespace in + the pattern (other than in a character class) and characters between a + # outside a character class and the next newline are ignored. An escap- + ing backslash can be used to include a whitespace or # character as + part of the pattern. + + If you want to remove the special meaning from a sequence of charac- + ters, you can do so by putting them between \Q and \E. This is differ- + ent from Perl in that $ and @ are handled as literals in \Q...\E + sequences in PCRE, whereas in Perl, $ and @ cause variable interpola- + tion. Note the following examples: + + Pattern PCRE matches Perl matches + + \Qabc$xyz\E abc$xyz abc followed by the + contents of $xyz + \Qabc\$xyz\E abc\$xyz abc\$xyz + \Qabc\E\$\Qxyz\E abc$xyz abc$xyz + + The \Q...\E sequence is recognized both inside and outside character + classes. + + Non-printing characters + + A second use of backslash provides a way of encoding non-printing char- + acters in patterns in a visible manner. There is no restriction on the + appearance of non-printing characters, apart from the binary zero that + terminates a pattern, but when a pattern is being prepared by text + editing, it is usually easier to use one of the following escape + sequences than the binary character it represents: + + \a alarm, that is, the BEL character (hex 07) + \cx "control-x", where x is any character + \e escape (hex 1B) + \f formfeed (hex 0C) + \n newline (hex 0A) + \r carriage return (hex 0D) + \t tab (hex 09) + \ddd character with octal code ddd, or backreference + \xhh character with hex code hh + \x{hhh..} character with hex code hhh.. + + The precise effect of \cx is as follows: if x is a lower case letter, + it is converted to upper case. Then bit 6 of the character (hex 40) is + inverted. Thus \cz becomes hex 1A, but \c{ becomes hex 3B, while \c; + becomes hex 7B. + + After \x, from zero to two hexadecimal digits are read (letters can be + in upper or lower case). Any number of hexadecimal digits may appear + between \x{ and }, but the value of the character code must be less + than 256 in non-UTF-8 mode, and less than 2**31 in UTF-8 mode (that is, + the maximum hexadecimal value is 7FFFFFFF). If characters other than + hexadecimal digits appear between \x{ and }, or if there is no termi- + nating }, this form of escape is not recognized. Instead, the initial + \x will be interpreted as a basic hexadecimal escape, with no following + digits, giving a character whose value is zero. + + Characters whose value is less than 256 can be defined by either of the + two syntaxes for \x. There is no difference in the way they are han- + dled. For example, \xdc is exactly the same as \x{dc}. + + After \0 up to two further octal digits are read. If there are fewer + than two digits, just those that are present are used. Thus the + sequence \0\x\07 specifies two binary zeros followed by a BEL character + (code value 7). Make sure you supply two digits after the initial zero + if the pattern character that follows is itself an octal digit. + + The handling of a backslash followed by a digit other than 0 is compli- + cated. Outside a character class, PCRE reads it and any following dig- + its as a decimal number. If the number is less than 10, or if there + have been at least that many previous capturing left parentheses in the + expression, the entire sequence is taken as a back reference. A + description of how this works is given later, following the discussion + of parenthesized subpatterns. + + Inside a character class, or if the decimal number is greater than 9 + and there have not been that many capturing subpatterns, PCRE re-reads + up to three octal digits following the backslash, ane uses them to gen- + erate a data character. Any subsequent digits stand for themselves. In + non-UTF-8 mode, the value of a character specified in octal must be + less than \400. In UTF-8 mode, values up to \777 are permitted. For + example: + + \040 is another way of writing a space + \40 is the same, provided there are fewer than 40 + previous capturing subpatterns + \7 is always a back reference + \11 might be a back reference, or another way of + writing a tab + \011 is always a tab + \0113 is a tab followed by the character "3" + \113 might be a back reference, otherwise the + character with octal code 113 + \377 might be a back reference, otherwise + the byte consisting entirely of 1 bits + \81 is either a back reference, or a binary zero + followed by the two characters "8" and "1" + + Note that octal values of 100 or greater must not be introduced by a + leading zero, because no more than three octal digits are ever read. + + All the sequences that define a single character value can be used both + inside and outside character classes. In addition, inside a character + class, the sequence \b is interpreted as the backspace character (hex + 08), and the sequence \X is interpreted as the character "X". Outside a + character class, these sequences have different meanings (see below). + + Generic character types + + The third use of backslash is for specifying generic character types. + The following are always recognized: + + \d any decimal digit + \D any character that is not a decimal digit + \s any whitespace character + \S any character that is not a whitespace character + \w any "word" character + \W any "non-word" character + + Each pair of escape sequences partitions the complete set of characters + into two disjoint sets. Any given character matches one, and only one, + of each pair. + + These character type sequences can appear both inside and outside char- + acter classes. They each match one character of the appropriate type. + If the current matching point is at the end of the subject string, all + of them fail, since there is no character to match. + + For compatibility with Perl, \s does not match the VT character (code + 11). This makes it different from the the POSIX "space" class. The \s + characters are HT (9), LF (10), FF (12), CR (13), and space (32). (If + "use locale;" is included in a Perl script, \s may match the VT charac- + ter. In PCRE, it never does.) + + A "word" character is an underscore or any character less than 256 that + is a letter or digit. The definition of letters and digits is con- + trolled by PCRE's low-valued character tables, and may vary if locale- + specific matching is taking place (see "Locale support" in the pcreapi + page). For example, in the "fr_FR" (French) locale, some character + codes greater than 128 are used for accented letters, and these are + matched by \w. + + In UTF-8 mode, characters with values greater than 128 never match \d, + \s, or \w, and always match \D, \S, and \W. This is true even when Uni- + code character property support is available. The use of locales with + Unicode is discouraged. + + Unicode character properties + + When PCRE is built with Unicode character property support, three addi- + tional escape sequences to match character properties are available + when UTF-8 mode is selected. They are: + + \p{xx} a character with the xx property + \P{xx} a character without the xx property + \X an extended Unicode sequence + + The property names represented by xx above are limited to the Unicode + script names, the general category properties, and "Any", which matches + any character (including newline). Other properties such as "InMusical- + Symbols" are not currently supported by PCRE. Note that \P{Any} does + not match any characters, so always causes a match failure. + + Sets of Unicode characters are defined as belonging to certain scripts. + A character from one of these sets can be matched using a script name. + For example: + + \p{Greek} + \P{Han} + + Those that are not part of an identified script are lumped together as + "Common". The current list of scripts is: + + Arabic, Armenian, Bengali, Bopomofo, Braille, Buginese, Buhid, Cana- + dian_Aboriginal, Cherokee, Common, Coptic, Cypriot, Cyrillic, Deseret, + Devanagari, Ethiopic, Georgian, Glagolitic, Gothic, Greek, Gujarati, + Gurmukhi, Han, Hangul, Hanunoo, Hebrew, Hiragana, Inherited, Kannada, + Katakana, Kharoshthi, Khmer, Lao, Latin, Limbu, Linear_B, Malayalam, + Mongolian, Myanmar, New_Tai_Lue, Ogham, Old_Italic, Old_Persian, Oriya, + Osmanya, Runic, Shavian, Sinhala, Syloti_Nagri, Syriac, Tagalog, Tag- + banwa, Tai_Le, Tamil, Telugu, Thaana, Thai, Tibetan, Tifinagh, + Ugaritic, Yi. + + Each character has exactly one general category property, specified by + a two-letter abbreviation. For compatibility with Perl, negation can be + specified by including a circumflex between the opening brace and the + property name. For example, \p{^Lu} is the same as \P{Lu}. + + If only one letter is specified with \p or \P, it includes all the gen- + eral category properties that start with that letter. In this case, in + the absence of negation, the curly brackets in the escape sequence are + optional; these two examples have the same effect: + + \p{L} + \pL + + The following general category property codes are supported: + + C Other + Cc Control + Cf Format + Cn Unassigned + Co Private use + Cs Surrogate + + L Letter + Ll Lower case letter + Lm Modifier letter + Lo Other letter + Lt Title case letter + Lu Upper case letter + + M Mark + Mc Spacing mark + Me Enclosing mark + Mn Non-spacing mark + + N Number + Nd Decimal number + Nl Letter number + No Other number + + P Punctuation + Pc Connector punctuation + Pd Dash punctuation + Pe Close punctuation + Pf Final punctuation + Pi Initial punctuation + Po Other punctuation + Ps Open punctuation + + S Symbol + Sc Currency symbol + Sk Modifier symbol + Sm Mathematical symbol + So Other symbol + + Z Separator + Zl Line separator + Zp Paragraph separator + Zs Space separator + + The special property L& is also supported: it matches a character that + has the Lu, Ll, or Lt property, in other words, a letter that is not + classified as a modifier or "other". + + The long synonyms for these properties that Perl supports (such as + \p{Letter}) are not supported by PCRE, nor is it permitted to prefix + any of these properties with "Is". + + No character that is in the Unicode table has the Cn (unassigned) prop- + erty. Instead, this property is assumed for any code point that is not + in the Unicode table. + + Specifying caseless matching does not affect these escape sequences. + For example, \p{Lu} always matches only upper case letters. + + The \X escape matches any number of Unicode characters that form an + extended Unicode sequence. \X is equivalent to + + (?>\PM\pM*) + + That is, it matches a character without the "mark" property, followed + by zero or more characters with the "mark" property, and treats the + sequence as an atomic group (see below). Characters with the "mark" + property are typically accents that affect the preceding character. + + Matching characters by Unicode property is not fast, because PCRE has + to search a structure that contains data for over fifteen thousand + characters. That is why the traditional escape sequences such as \d and + \w do not use Unicode properties in PCRE. + + Simple assertions + + The fourth use of backslash is for certain simple assertions. An asser- + tion specifies a condition that has to be met at a particular point in + a match, without consuming any characters from the subject string. The + use of subpatterns for more complicated assertions is described below. + The backslashed assertions are: + + \b matches at a word boundary + \B matches when not at a word boundary + \A matches at start of subject + \Z matches at end of subject or before newline at end + \z matches at end of subject + \G matches at first matching position in subject + + These assertions may not appear in character classes (but note that \b + has a different meaning, namely the backspace character, inside a char- + acter class). + + A word boundary is a position in the subject string where the current + character and the previous character do not both match \w or \W (i.e. + one matches \w and the other matches \W), or the start or end of the + string if the first or last character matches \w, respectively. + + The \A, \Z, and \z assertions differ from the traditional circumflex + and dollar (described in the next section) in that they only ever match + at the very start and end of the subject string, whatever options are + set. Thus, they are independent of multiline mode. These three asser- + tions are not affected by the PCRE_NOTBOL or PCRE_NOTEOL options, which + affect only the behaviour of the circumflex and dollar metacharacters. + However, if the startoffset argument of pcre_exec() is non-zero, indi- + cating that matching is to start at a point other than the beginning of + the subject, \A can never match. The difference between \Z and \z is + that \Z matches before a newline at the end of the string as well as at + the very end, whereas \z matches only at the end. + + The \G assertion is true only when the current matching position is at + the start point of the match, as specified by the startoffset argument + of pcre_exec(). It differs from \A when the value of startoffset is + non-zero. By calling pcre_exec() multiple times with appropriate argu- + ments, you can mimic Perl's /g option, and it is in this kind of imple- + mentation where \G can be useful. + + Note, however, that PCRE's interpretation of \G, as the start of the + current match, is subtly different from Perl's, which defines it as the + end of the previous match. In Perl, these can be different when the + previously matched string was empty. Because PCRE does just one match + at a time, it cannot reproduce this behaviour. + + If all the alternatives of a pattern begin with \G, the expression is + anchored to the starting match position, and the "anchored" flag is set + in the compiled regular expression. + + +CIRCUMFLEX AND DOLLAR + + Outside a character class, in the default matching mode, the circumflex + character is an assertion that is true only if the current matching + point is at the start of the subject string. If the startoffset argu- + ment of pcre_exec() is non-zero, circumflex can never match if the + PCRE_MULTILINE option is unset. Inside a character class, circumflex + has an entirely different meaning (see below). + + Circumflex need not be the first character of the pattern if a number + of alternatives are involved, but it should be the first thing in each + alternative in which it appears if the pattern is ever to match that + branch. If all possible alternatives start with a circumflex, that is, + if the pattern is constrained to match only at the start of the sub- + ject, it is said to be an "anchored" pattern. (There are also other + constructs that can cause a pattern to be anchored.) + + A dollar character is an assertion that is true only if the current + matching point is at the end of the subject string, or immediately + before a newline at the end of the string (by default). Dollar need not + be the last character of the pattern if a number of alternatives are + involved, but it should be the last item in any branch in which it + appears. Dollar has no special meaning in a character class. + + The meaning of dollar can be changed so that it matches only at the + very end of the string, by setting the PCRE_DOLLAR_ENDONLY option at + compile time. This does not affect the \Z assertion. + + The meanings of the circumflex and dollar characters are changed if the + PCRE_MULTILINE option is set. When this is the case, a circumflex + matches immediately after internal newlines as well as at the start of + the subject string. It does not match after a newline that ends the + string. A dollar matches before any newlines in the string, as well as + at the very end, when PCRE_MULTILINE is set. When newline is specified + as the two-character sequence CRLF, isolated CR and LF characters do + not indicate newlines. + + For example, the pattern /^abc$/ matches the subject string "def\nabc" + (where \n represents a newline) in multiline mode, but not otherwise. + Consequently, patterns that are anchored in single line mode because + all branches start with ^ are not anchored in multiline mode, and a + match for circumflex is possible when the startoffset argument of + pcre_exec() is non-zero. The PCRE_DOLLAR_ENDONLY option is ignored if + PCRE_MULTILINE is set. + + Note that the sequences \A, \Z, and \z can be used to match the start + and end of the subject in both modes, and if all branches of a pattern + start with \A it is always anchored, whether or not PCRE_MULTILINE is + set. + + +FULL STOP (PERIOD, DOT) + + Outside a character class, a dot in the pattern matches any one charac- + ter in the subject string except (by default) a character that signi- + fies the end of a line. In UTF-8 mode, the matched character may be + more than one byte long. When a line ending is defined as a single + character (CR or LF), dot never matches that character; when the two- + character sequence CRLF is used, dot does not match CR if it is immedi- + ately followed by LF, but otherwise it matches all characters (includ- + ing isolated CRs and LFs). + + The behaviour of dot with regard to newlines can be changed. If the + PCRE_DOTALL option is set, a dot matches any one character, without + exception. If newline is defined as the two-character sequence CRLF, it + takes two dots to match it. + + The handling of dot is entirely independent of the handling of circum- + flex and dollar, the only relationship being that they both involve + newlines. Dot has no special meaning in a character class. + + +MATCHING A SINGLE BYTE + + Outside a character class, the escape sequence \C matches any one byte, + both in and out of UTF-8 mode. Unlike a dot, it always matches CR and + LF. The feature is provided in Perl in order to match individual bytes + in UTF-8 mode. Because it breaks up UTF-8 characters into individual + bytes, what remains in the string may be a malformed UTF-8 string. For + this reason, the \C escape sequence is best avoided. + + PCRE does not allow \C to appear in lookbehind assertions (described + below), because in UTF-8 mode this would make it impossible to calcu- + late the length of the lookbehind. + + +SQUARE BRACKETS AND CHARACTER CLASSES + + An opening square bracket introduces a character class, terminated by a + closing square bracket. A closing square bracket on its own is not spe- + cial. If a closing square bracket is required as a member of the class, + it should be the first data character in the class (after an initial + circumflex, if present) or escaped with a backslash. + + A character class matches a single character in the subject. In UTF-8 + mode, the character may occupy more than one byte. A matched character + must be in the set of characters defined by the class, unless the first + character in the class definition is a circumflex, in which case the + subject character must not be in the set defined by the class. If a + circumflex is actually required as a member of the class, ensure it is + not the first character, or escape it with a backslash. + + For example, the character class [aeiou] matches any lower case vowel, + while [^aeiou] matches any character that is not a lower case vowel. + Note that a circumflex is just a convenient notation for specifying the + characters that are in the class by enumerating those that are not. A + class that starts with a circumflex is not an assertion: it still con- + sumes a character from the subject string, and therefore it fails if + the current pointer is at the end of the string. + + In UTF-8 mode, characters with values greater than 255 can be included + in a class as a literal string of bytes, or by using the \x{ escaping + mechanism. + + When caseless matching is set, any letters in a class represent both + their upper case and lower case versions, so for example, a caseless + [aeiou] matches "A" as well as "a", and a caseless [^aeiou] does not + match "A", whereas a caseful version would. In UTF-8 mode, PCRE always + understands the concept of case for characters whose values are less + than 128, so caseless matching is always possible. For characters with + higher values, the concept of case is supported if PCRE is compiled + with Unicode property support, but not otherwise. If you want to use + caseless matching for characters 128 and above, you must ensure that + PCRE is compiled with Unicode property support as well as with UTF-8 + support. + + Characters that might indicate line breaks (CR and LF) are never + treated in any special way when matching character classes, whatever + line-ending sequence is in use, and whatever setting of the PCRE_DOTALL + and PCRE_MULTILINE options is used. A class such as [^a] always matches + one of these characters. + + The minus (hyphen) character can be used to specify a range of charac- + ters in a character class. For example, [d-m] matches any letter + between d and m, inclusive. If a minus character is required in a + class, it must be escaped with a backslash or appear in a position + where it cannot be interpreted as indicating a range, typically as the + first or last character in the class. + + It is not possible to have the literal character "]" as the end charac- + ter of a range. A pattern such as [W-]46] is interpreted as a class of + two characters ("W" and "-") followed by a literal string "46]", so it + would match "W46]" or "-46]". However, if the "]" is escaped with a + backslash it is interpreted as the end of range, so [W-\]46] is inter- + preted as a class containing a range followed by two other characters. + The octal or hexadecimal representation of "]" can also be used to end + a range. + + Ranges operate in the collating sequence of character values. They can + also be used for characters specified numerically, for example + [\000-\037]. In UTF-8 mode, ranges can include characters whose values + are greater than 255, for example [\x{100}-\x{2ff}]. + + If a range that includes letters is used when caseless matching is set, + it matches the letters in either case. For example, [W-c] is equivalent + to [][\\^_`wxyzabc], matched caselessly, and in non-UTF-8 mode, if + character tables for the "fr_FR" locale are in use, [\xc8-\xcb] matches + accented E characters in both cases. In UTF-8 mode, PCRE supports the + concept of case for characters with values greater than 128 only when + it is compiled with Unicode property support. + + The character types \d, \D, \p, \P, \s, \S, \w, and \W may also appear + in a character class, and add the characters that they match to the + class. For example, [\dABCDEF] matches any hexadecimal digit. A circum- + flex can conveniently be used with the upper case character types to + specify a more restricted set of characters than the matching lower + case type. For example, the class [^\W_] matches any letter or digit, + but not underscore. + + The only metacharacters that are recognized in character classes are + backslash, hyphen (only where it can be interpreted as specifying a + range), circumflex (only at the start), opening square bracket (only + when it can be interpreted as introducing a POSIX class name - see the + next section), and the terminating closing square bracket. However, + escaping other non-alphanumeric characters does no harm. + + +POSIX CHARACTER CLASSES + + Perl supports the POSIX notation for character classes. This uses names + enclosed by [: and :] within the enclosing square brackets. PCRE also + supports this notation. For example, + + [01[:alpha:]%] + + matches "0", "1", any alphabetic character, or "%". The supported class + names are + + alnum letters and digits + alpha letters + ascii character codes 0 - 127 + blank space or tab only + cntrl control characters + digit decimal digits (same as \d) + graph printing characters, excluding space + lower lower case letters + print printing characters, including space + punct printing characters, excluding letters and digits + space white space (not quite the same as \s) + upper upper case letters + word "word" characters (same as \w) + xdigit hexadecimal digits + + The "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13), + and space (32). Notice that this list includes the VT character (code + 11). This makes "space" different to \s, which does not include VT (for + Perl compatibility). + + The name "word" is a Perl extension, and "blank" is a GNU extension + from Perl 5.8. Another Perl extension is negation, which is indicated + by a ^ character after the colon. For example, + + [12[:^digit:]] + + matches "1", "2", or any non-digit. PCRE (and Perl) also recognize the + POSIX syntax [.ch.] and [=ch=] where "ch" is a "collating element", but + these are not supported, and an error is given if they are encountered. + + In UTF-8 mode, characters with values greater than 128 do not match any + of the POSIX character classes. + + +VERTICAL BAR + + Vertical bar characters are used to separate alternative patterns. For + example, the pattern + + gilbert|sullivan + + matches either "gilbert" or "sullivan". Any number of alternatives may + appear, and an empty alternative is permitted (matching the empty + string). The matching process tries each alternative in turn, from left + to right, and the first one that succeeds is used. If the alternatives + are within a subpattern (defined below), "succeeds" means matching the + rest of the main pattern as well as the alternative in the subpattern. + + +INTERNAL OPTION SETTING + + The settings of the PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and + PCRE_EXTENDED options can be changed from within the pattern by a + sequence of Perl option letters enclosed between "(?" and ")". The + option letters are + + i for PCRE_CASELESS + m for PCRE_MULTILINE + s for PCRE_DOTALL + x for PCRE_EXTENDED + + For example, (?im) sets caseless, multiline matching. It is also possi- + ble to unset these options by preceding the letter with a hyphen, and a + combined setting and unsetting such as (?im-sx), which sets PCRE_CASE- + LESS and PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, + is also permitted. If a letter appears both before and after the + hyphen, the option is unset. + + When an option change occurs at top level (that is, not inside subpat- + tern parentheses), the change applies to the remainder of the pattern + that follows. If the change is placed right at the start of a pattern, + PCRE extracts it into the global options (and it will therefore show up + in data extracted by the pcre_fullinfo() function). + + An option change within a subpattern affects only that part of the cur- + rent pattern that follows it, so + + (a(?i)b)c + + matches abc and aBc and no other strings (assuming PCRE_CASELESS is not + used). By this means, options can be made to have different settings + in different parts of the pattern. Any changes made in one alternative + do carry on into subsequent branches within the same subpattern. For + example, + + (a(?i)b|c) + + matches "ab", "aB", "c", and "C", even though when matching "C" the + first branch is abandoned before the option setting. This is because + the effects of option settings happen at compile time. There would be + some very weird behaviour otherwise. + + The PCRE-specific options PCRE_DUPNAMES, PCRE_UNGREEDY, and PCRE_EXTRA + can be changed in the same way as the Perl-compatible options by using + the characters J, U and X respectively. + + +SUBPATTERNS + + Subpatterns are delimited by parentheses (round brackets), which can be + nested. Turning part of a pattern into a subpattern does two things: + + 1. It localizes a set of alternatives. For example, the pattern + + cat(aract|erpillar|) + + matches one of the words "cat", "cataract", or "caterpillar". Without + the parentheses, it would match "cataract", "erpillar" or the empty + string. + + 2. It sets up the subpattern as a capturing subpattern. This means + that, when the whole pattern matches, that portion of the subject + string that matched the subpattern is passed back to the caller via the + ovector argument of pcre_exec(). Opening parentheses are counted from + left to right (starting from 1) to obtain numbers for the capturing + subpatterns. + + For example, if the string "the red king" is matched against the pat- + tern + + the ((red|white) (king|queen)) + + the captured substrings are "red king", "red", and "king", and are num- + bered 1, 2, and 3, respectively. + + The fact that plain parentheses fulfil two functions is not always + helpful. There are often times when a grouping subpattern is required + without a capturing requirement. If an opening parenthesis is followed + by a question mark and a colon, the subpattern does not do any captur- + ing, and is not counted when computing the number of any subsequent + capturing subpatterns. For example, if the string "the white queen" is + matched against the pattern + + the ((?:red|white) (king|queen)) + + the captured substrings are "white queen" and "queen", and are numbered + 1 and 2. The maximum number of capturing subpatterns is 65535, and the + maximum depth of nesting of all subpatterns, both capturing and non- + capturing, is 200. + + As a convenient shorthand, if any option settings are required at the + start of a non-capturing subpattern, the option letters may appear + between the "?" and the ":". Thus the two patterns + + (?i:saturday|sunday) + (?:(?i)saturday|sunday) + + match exactly the same set of strings. Because alternative branches are + tried from left to right, and options are not reset until the end of + the subpattern is reached, an option setting in one branch does affect + subsequent branches, so the above patterns match "SUNDAY" as well as + "Saturday". + + +NAMED SUBPATTERNS + + Identifying capturing parentheses by number is simple, but it can be + very hard to keep track of the numbers in complicated regular expres- + sions. Furthermore, if an expression is modified, the numbers may + change. To help with this difficulty, PCRE supports the naming of sub- + patterns, something that Perl does not provide. The Python syntax + (?P<name>...) is used. References to capturing parentheses from other + parts of the pattern, such as backreferences, recursion, and condi- + tions, can be made by name as well as by number. + + Names consist of up to 32 alphanumeric characters and underscores. + Named capturing parentheses are still allocated numbers as well as + names. The PCRE API provides function calls for extracting the name-to- + number translation table from a compiled pattern. There is also a con- + venience function for extracting a captured substring by name. + + By default, a name must be unique within a pattern, but it is possible + to relax this constraint by setting the PCRE_DUPNAMES option at compile + time. This can be useful for patterns where only one instance of the + named parentheses can match. Suppose you want to match the name of a + weekday, either as a 3-letter abbreviation or as the full name, and in + both cases you want to extract the abbreviation. This pattern (ignoring + the line breaks) does the job: + + (?P<DN>Mon|Fri|Sun)(?:day)?| + (?P<DN>Tue)(?:sday)?| + (?P<DN>Wed)(?:nesday)?| + (?P<DN>Thu)(?:rsday)?| + (?P<DN>Sat)(?:urday)? + + There are five capturing substrings, but only one is ever set after a + match. The convenience function for extracting the data by name + returns the substring for the first, and in this example, the only, + subpattern of that name that matched. This saves searching to find + which numbered subpattern it was. If you make a reference to a non- + unique named subpattern from elsewhere in the pattern, the one that + corresponds to the lowest number is used. For further details of the + interfaces for handling named subpatterns, see the pcreapi documenta- + tion. + + +REPETITION + + Repetition is specified by quantifiers, which can follow any of the + following items: + + a literal data character + the . metacharacter + the \C escape sequence + the \X escape sequence (in UTF-8 mode with Unicode properties) + an escape such as \d that matches a single character + a character class + a back reference (see next section) + a parenthesized subpattern (unless it is an assertion) + + The general repetition quantifier specifies a minimum and maximum num- + ber of permitted matches, by giving the two numbers in curly brackets + (braces), separated by a comma. The numbers must be less than 65536, + and the first must be less than or equal to the second. For example: + + z{2,4} + + matches "zz", "zzz", or "zzzz". A closing brace on its own is not a + special character. If the second number is omitted, but the comma is + present, there is no upper limit; if the second number and the comma + are both omitted, the quantifier specifies an exact number of required + matches. Thus + + [aeiou]{3,} + + matches at least 3 successive vowels, but may match many more, while + + \d{8} + + matches exactly 8 digits. An opening curly bracket that appears in a + position where a quantifier is not allowed, or one that does not match + the syntax of a quantifier, is taken as a literal character. For exam- + ple, {,6} is not a quantifier, but a literal string of four characters. + + In UTF-8 mode, quantifiers apply to UTF-8 characters rather than to + individual bytes. Thus, for example, \x{100}{2} matches two UTF-8 char- + acters, each of which is represented by a two-byte sequence. Similarly, + when Unicode property support is available, \X{3} matches three Unicode + extended sequences, each of which may be several bytes long (and they + may be of different lengths). + + The quantifier {0} is permitted, causing the expression to behave as if + the previous item and the quantifier were not present. + + For convenience (and historical compatibility) the three most common + quantifiers have single-character abbreviations: + + * is equivalent to {0,} + + is equivalent to {1,} + ? is equivalent to {0,1} + + It is possible to construct infinite loops by following a subpattern + that can match no characters with a quantifier that has no upper limit, + for example: + + (a?)* + + Earlier versions of Perl and PCRE used to give an error at compile time + for such patterns. However, because there are cases where this can be + useful, such patterns are now accepted, but if any repetition of the + subpattern does in fact match no characters, the loop is forcibly bro- + ken. + + By default, the quantifiers are "greedy", that is, they match as much + as possible (up to the maximum number of permitted times), without + causing the rest of the pattern to fail. The classic example of where + this gives problems is in trying to match comments in C programs. These + appear between /* and */ and within the comment, individual * and / + characters may appear. An attempt to match C comments by applying the + pattern + + /\*.*\*/ + + to the string + + /* first comment */ not comment /* second comment */ + + fails, because it matches the entire string owing to the greediness of + the .* item. + + However, if a quantifier is followed by a question mark, it ceases to + be greedy, and instead matches the minimum number of times possible, so + the pattern + + /\*.*?\*/ + + does the right thing with the C comments. The meaning of the various + quantifiers is not otherwise changed, just the preferred number of + matches. Do not confuse this use of question mark with its use as a + quantifier in its own right. Because it has two uses, it can sometimes + appear doubled, as in + + \d??\d + + which matches one digit by preference, but can match two if that is the + only way the rest of the pattern matches. + + If the PCRE_UNGREEDY option is set (an option which is not available in + Perl), the quantifiers are not greedy by default, but individual ones + can be made greedy by following them with a question mark. In other + words, it inverts the default behaviour. + + When a parenthesized subpattern is quantified with a minimum repeat + count that is greater than 1 or with a limited maximum, more memory is + required for the compiled pattern, in proportion to the size of the + minimum or maximum. + + If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equiv- + alent to Perl's /s) is set, thus allowing the . to match newlines, the + pattern is implicitly anchored, because whatever follows will be tried + against every character position in the subject string, so there is no + point in retrying the overall match at any position after the first. + PCRE normally treats such a pattern as though it were preceded by \A. + + In cases where it is known that the subject string contains no new- + lines, it is worth setting PCRE_DOTALL in order to obtain this opti- + mization, or alternatively using ^ to indicate anchoring explicitly. + + However, there is one situation where the optimization cannot be used. + When .* is inside capturing parentheses that are the subject of a + backreference elsewhere in the pattern, a match at the start may fail, + and a later one succeed. Consider, for example: + + (.*)abc\1 + + If the subject is "xyz123abc123" the match point is the fourth charac- + ter. For this reason, such a pattern is not implicitly anchored. + + When a capturing subpattern is repeated, the value captured is the sub- + string that matched the final iteration. For example, after + + (tweedle[dume]{3}\s*)+ + + has matched "tweedledum tweedledee" the value of the captured substring + is "tweedledee". However, if there are nested capturing subpatterns, + the corresponding captured values may have been set in previous itera- + tions. For example, after + + /(a|(b))+/ + + matches "aba" the value of the second captured substring is "b". + + +ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS + + With both maximizing and minimizing repetition, failure of what follows + normally causes the repeated item to be re-evaluated to see if a dif- + ferent number of repeats allows the rest of the pattern to match. Some- + times it is useful to prevent this, either to change the nature of the + match, or to cause it fail earlier than it otherwise might, when the + author of the pattern knows there is no point in carrying on. + + Consider, for example, the pattern \d+foo when applied to the subject + line + + 123456bar + + After matching all 6 digits and then failing to match "foo", the normal + action of the matcher is to try again with only 5 digits matching the + \d+ item, and then with 4, and so on, before ultimately failing. + "Atomic grouping" (a term taken from Jeffrey Friedl's book) provides + the means for specifying that once a subpattern has matched, it is not + to be re-evaluated in this way. + + If we use atomic grouping for the previous example, the matcher would + give up immediately on failing to match "foo" the first time. The nota- + tion is a kind of special parenthesis, starting with (?> as in this + example: + + (?>\d+)foo + + This kind of parenthesis "locks up" the part of the pattern it con- + tains once it has matched, and a failure further into the pattern is + prevented from backtracking into it. Backtracking past it to previous + items, however, works as normal. + + An alternative description is that a subpattern of this type matches + the string of characters that an identical standalone pattern would + match, if anchored at the current point in the subject string. + + Atomic grouping subpatterns are not capturing subpatterns. Simple cases + such as the above example can be thought of as a maximizing repeat that + must swallow everything it can. So, while both \d+ and \d+? are pre- + pared to adjust the number of digits they match in order to make the + rest of the pattern match, (?>\d+) can only match an entire sequence of + digits. + + Atomic groups in general can of course contain arbitrarily complicated + subpatterns, and can be nested. However, when the subpattern for an + atomic group is just a single repeated item, as in the example above, a + simpler notation, called a "possessive quantifier" can be used. This + consists of an additional + character following a quantifier. Using + this notation, the previous example can be rewritten as + + \d++foo + + Possessive quantifiers are always greedy; the setting of the + PCRE_UNGREEDY option is ignored. They are a convenient notation for the + simpler forms of atomic group. However, there is no difference in the + meaning or processing of a possessive quantifier and the equivalent + atomic group. + + The possessive quantifier syntax is an extension to the Perl syntax. + Jeffrey Friedl originated the idea (and the name) in the first edition + of his book. Mike McCloskey liked it, so implemented it when he built + Sun's Java package, and PCRE copied it from there. + + When a pattern contains an unlimited repeat inside a subpattern that + can itself be repeated an unlimited number of times, the use of an + atomic group is the only way to avoid some failing matches taking a + very long time indeed. The pattern + + (\D+|<\d+>)*[!?] + + matches an unlimited number of substrings that either consist of non- + digits, or digits enclosed in <>, followed by either ! or ?. When it + matches, it runs quickly. However, if it is applied to + + aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa + + it takes a long time before reporting failure. This is because the + string can be divided between the internal \D+ repeat and the external + * repeat in a large number of ways, and all have to be tried. (The + example uses [!?] rather than a single character at the end, because + both PCRE and Perl have an optimization that allows for fast failure + when a single character is used. They remember the last single charac- + ter that is required for a match, and fail early if it is not present + in the string.) If the pattern is changed so that it uses an atomic + group, like this: + + ((?>\D+)|<\d+>)*[!?] + + sequences of non-digits cannot be broken, and failure happens quickly. + + +BACK REFERENCES + + Outside a character class, a backslash followed by a digit greater than + 0 (and possibly further digits) is a back reference to a capturing sub- + pattern earlier (that is, to its left) in the pattern, provided there + have been that many previous capturing left parentheses. + + However, if the decimal number following the backslash is less than 10, + it is always taken as a back reference, and causes an error only if + there are not that many capturing left parentheses in the entire pat- + tern. In other words, the parentheses that are referenced need not be + to the left of the reference for numbers less than 10. A "forward back + reference" of this type can make sense when a repetition is involved + and the subpattern to the right has participated in an earlier itera- + tion. + + It is not possible to have a numerical "forward back reference" to sub- + pattern whose number is 10 or more. However, a back reference to any + subpattern is possible using named parentheses (see below). See also + the subsection entitled "Non-printing characters" above for further + details of the handling of digits following a backslash. + + A back reference matches whatever actually matched the capturing sub- + pattern in the current subject string, rather than anything matching + the subpattern itself (see "Subpatterns as subroutines" below for a way + of doing that). So the pattern + + (sens|respons)e and \1ibility + + matches "sense and sensibility" and "response and responsibility", but + not "sense and responsibility". If caseful matching is in force at the + time of the back reference, the case of letters is relevant. For exam- + ple, + + ((?i)rah)\s+\1 + + matches "rah rah" and "RAH RAH", but not "RAH rah", even though the + original capturing subpattern is matched caselessly. + + Back references to named subpatterns use the Python syntax (?P=name). + We could rewrite the above example as follows: + + (?P<p1>(?i)rah)\s+(?P=p1) + + A subpattern that is referenced by name may appear in the pattern + before or after the reference. + + There may be more than one back reference to the same subpattern. If a + subpattern has not actually been used in a particular match, any back + references to it always fail. For example, the pattern + + (a|(bc))\2 + + always fails if it starts to match "a" rather than "bc". Because there + may be many capturing parentheses in a pattern, all digits following + the backslash are taken as part of a potential back reference number. + If the pattern continues with a digit character, some delimiter must be + used to terminate the back reference. If the PCRE_EXTENDED option is + set, this can be whitespace. Otherwise an empty comment (see "Com- + ments" below) can be used. + + A back reference that occurs inside the parentheses to which it refers + fails when the subpattern is first used, so, for example, (a\1) never + matches. However, such references can be useful inside repeated sub- + patterns. For example, the pattern + + (a|b\1)+ + + matches any number of "a"s and also "aba", "ababbaa" etc. At each iter- + ation of the subpattern, the back reference matches the character + string corresponding to the previous iteration. In order for this to + work, the pattern must be such that the first iteration does not need + to match the back reference. This can be done using alternation, as in + the example above, or by a quantifier with a minimum of zero. + + +ASSERTIONS + + An assertion is a test on the characters following or preceding the + current matching point that does not actually consume any characters. + The simple assertions coded as \b, \B, \A, \G, \Z, \z, ^ and $ are + described above. + + More complicated assertions are coded as subpatterns. There are two + kinds: those that look ahead of the current position in the subject + string, and those that look behind it. An assertion subpattern is + matched in the normal way, except that it does not cause the current + matching position to be changed. + + Assertion subpatterns are not capturing subpatterns, and may not be + repeated, because it makes no sense to assert the same thing several + times. If any kind of assertion contains capturing subpatterns within + it, these are counted for the purposes of numbering the capturing sub- + patterns in the whole pattern. However, substring capturing is carried + out only for positive assertions, because it does not make sense for + negative assertions. + + Lookahead assertions + + Lookahead assertions start with (?= for positive assertions and (?! for + negative assertions. For example, + + \w+(?=;) + + matches a word followed by a semicolon, but does not include the semi- + colon in the match, and + + foo(?!bar) + + matches any occurrence of "foo" that is not followed by "bar". Note + that the apparently similar pattern + + (?!foo)bar + + does not find an occurrence of "bar" that is preceded by something + other than "foo"; it finds any occurrence of "bar" whatsoever, because + the assertion (?!foo) is always true when the next three characters are + "bar". A lookbehind assertion is needed to achieve the other effect. + + If you want to force a matching failure at some point in a pattern, the + most convenient way to do it is with (?!) because an empty string + always matches, so an assertion that requires there not to be an empty + string must always fail. + + Lookbehind assertions + + Lookbehind assertions start with (?<= for positive assertions and (?<! + for negative assertions. For example, + + (?<!foo)bar + + does find an occurrence of "bar" that is not preceded by "foo". The + contents of a lookbehind assertion are restricted such that all the + strings it matches must have a fixed length. However, if there are sev- + eral top-level alternatives, they do not all have to have the same + fixed length. Thus + + (?<=bullock|donkey) + + is permitted, but + + (?<!dogs?|cats?) + + causes an error at compile time. Branches that match different length + strings are permitted only at the top level of a lookbehind assertion. + This is an extension compared with Perl (at least for 5.8), which + requires all branches to match the same length of string. An assertion + such as + + (?<=ab(c|de)) + + is not permitted, because its single top-level branch can match two + different lengths, but it is acceptable if rewritten to use two top- + level branches: + + (?<=abc|abde) + + The implementation of lookbehind assertions is, for each alternative, + to temporarily move the current position back by the fixed width and + then try to match. If there are insufficient characters before the cur- + rent position, the match is deemed to fail. + + PCRE does not allow the \C escape (which matches a single byte in UTF-8 + mode) to appear in lookbehind assertions, because it makes it impossi- + ble to calculate the length of the lookbehind. The \X escape, which can + match different numbers of bytes, is also not permitted. + + Atomic groups can be used in conjunction with lookbehind assertions to + specify efficient matching at the end of the subject string. Consider a + simple pattern such as + + abcd$ + + when applied to a long string that does not match. Because matching + proceeds from left to right, PCRE will look for each "a" in the subject + and then see if what follows matches the rest of the pattern. If the + pattern is specified as + + ^.*abcd$ + + the initial .* matches the entire string at first, but when this fails + (because there is no following "a"), it backtracks to match all but the + last character, then all but the last two characters, and so on. Once + again the search for "a" covers the entire string, from right to left, + so we are no better off. However, if the pattern is written as + + ^(?>.*)(?<=abcd) + + or, equivalently, using the possessive quantifier syntax, + + ^.*+(?<=abcd) + + there can be no backtracking for the .* item; it can match only the + entire string. The subsequent lookbehind assertion does a single test + on the last four characters. If it fails, the match fails immediately. + For long strings, this approach makes a significant difference to the + processing time. + + Using multiple assertions + + Several assertions (of any sort) may occur in succession. For example, + + (?<=\d{3})(?<!999)foo + + matches "foo" preceded by three digits that are not "999". Notice that + each of the assertions is applied independently at the same point in + the subject string. First there is a check that the previous three + characters are all digits, and then there is a check that the same + three characters are not "999". This pattern does not match "foo" pre- + ceded by six characters, the first of which are digits and the last + three of which are not "999". For example, it doesn't match "123abc- + foo". A pattern to do that is + + (?<=\d{3}...)(?<!999)foo + + This time the first assertion looks at the preceding six characters, + checking that the first three are digits, and then the second assertion + checks that the preceding three characters are not "999". + + Assertions can be nested in any combination. For example, + + (?<=(?<!foo)bar)baz + + matches an occurrence of "baz" that is preceded by "bar" which in turn + is not preceded by "foo", while + + (?<=\d{3}(?!999)...)foo + + is another pattern that matches "foo" preceded by three digits and any + three characters that are not "999". + + +CONDITIONAL SUBPATTERNS + + It is possible to cause the matching process to obey a subpattern con- + ditionally or to choose between two alternative subpatterns, depending + on the result of an assertion, or whether a previous capturing subpat- + tern matched or not. The two possible forms of conditional subpattern + are + + (?(condition)yes-pattern) + (?(condition)yes-pattern|no-pattern) + + If the condition is satisfied, the yes-pattern is used; otherwise the + no-pattern (if present) is used. If there are more than two alterna- + tives in the subpattern, a compile-time error occurs. + + There are three kinds of condition. If the text between the parentheses + consists of a sequence of digits, or a sequence of alphanumeric charac- + ters and underscores, the condition is satisfied if the capturing sub- + pattern of that number or name has previously matched. There is a pos- + sible ambiguity here, because subpattern names may consist entirely of + digits. PCRE looks first for a named subpattern; if it cannot find one + and the text consists entirely of digits, it looks for a subpattern of + that number, which must be greater than zero. Using subpattern names + that consist entirely of digits is not recommended. + + Consider the following pattern, which contains non-significant white + space to make it more readable (assume the PCRE_EXTENDED option) and to + divide it into three parts for ease of discussion: + + ( \( )? [^()]+ (?(1) \) ) + + The first part matches an optional opening parenthesis, and if that + character is present, sets it as the first captured substring. The sec- + ond part matches one or more characters that are not parentheses. The + third part is a conditional subpattern that tests whether the first set + of parentheses matched or not. If they did, that is, if subject started + with an opening parenthesis, the condition is true, and so the yes-pat- + tern is executed and a closing parenthesis is required. Otherwise, + since no-pattern is not present, the subpattern matches nothing. In + other words, this pattern matches a sequence of non-parentheses, + optionally enclosed in parentheses. Rewriting it to use a named subpat- + tern gives this: + + (?P<OPEN> \( )? [^()]+ (?(OPEN) \) ) + + If the condition is the string (R), and there is no subpattern with the + name R, the condition is satisfied if a recursive call to the pattern + or subpattern has been made. At "top level", the condition is false. + This is a PCRE extension. Recursive patterns are described in the next + section. + + If the condition is not a sequence of digits or (R), it must be an + assertion. This may be a positive or negative lookahead or lookbehind + assertion. Consider this pattern, again containing non-significant + white space, and with the two alternatives on the second line: + + (?(?=[^a-z]*[a-z]) + \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} ) + + The condition is a positive lookahead assertion that matches an + optional sequence of non-letters followed by a letter. In other words, + it tests for the presence of at least one letter in the subject. If a + letter is found, the subject is matched against the first alternative; + otherwise it is matched against the second. This pattern matches + strings in one of the two forms dd-aaa-dd or dd-dd-dd, where aaa are + letters and dd are digits. + + +COMMENTS + + The sequence (?# marks the start of a comment that continues up to the + next closing parenthesis. Nested parentheses are not permitted. The + characters that make up a comment play no part in the pattern matching + at all. + + If the PCRE_EXTENDED option is set, an unescaped # character outside a + character class introduces a comment that continues to immediately + after the next newline in the pattern. + + +RECURSIVE PATTERNS + + Consider the problem of matching a string in parentheses, allowing for + unlimited nested parentheses. Without the use of recursion, the best + that can be done is to use a pattern that matches up to some fixed + depth of nesting. It is not possible to handle an arbitrary nesting + depth. Perl provides a facility that allows regular expressions to + recurse (amongst other things). It does this by interpolating Perl code + in the expression at run time, and the code can refer to the expression + itself. A Perl pattern to solve the parentheses problem can be created + like this: + + $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x; + + The (?p{...}) item interpolates Perl code at run time, and in this case + refers recursively to the pattern in which it appears. Obviously, PCRE + cannot support the interpolation of Perl code. Instead, it supports + some special syntax for recursion of the entire pattern, and also for + individual subpattern recursion. + + The special item that consists of (? followed by a number greater than + zero and a closing parenthesis is a recursive call of the subpattern of + the given number, provided that it occurs inside that subpattern. (If + not, it is a "subroutine" call, which is described in the next sec- + tion.) The special item (?R) is a recursive call of the entire regular + expression. + + A recursive subpattern call is always treated as an atomic group. That + is, once it has matched some of the subject string, it is never re- + entered, even if it contains untried alternatives and there is a subse- + quent matching failure. + + This PCRE pattern solves the nested parentheses problem (assume the + PCRE_EXTENDED option is set so that white space is ignored): + + \( ( (?>[^()]+) | (?R) )* \) + + First it matches an opening parenthesis. Then it matches any number of + substrings which can either be a sequence of non-parentheses, or a + recursive match of the pattern itself (that is, a correctly parenthe- + sized substring). Finally there is a closing parenthesis. + + If this were part of a larger pattern, you would not want to recurse + the entire pattern, so instead you could use this: + + ( \( ( (?>[^()]+) | (?1) )* \) ) + + We have put the pattern into parentheses, and caused the recursion to + refer to them instead of the whole pattern. In a larger pattern, keep- + ing track of parenthesis numbers can be tricky. It may be more conve- + nient to use named parentheses instead. For this, PCRE uses (?P>name), + which is an extension to the Python syntax that PCRE uses for named + parentheses (Perl does not provide named parentheses). We could rewrite + the above example as follows: + + (?P<pn> \( ( (?>[^()]+) | (?P>pn) )* \) ) + + This particular example pattern contains nested unlimited repeats, and + so the use of atomic grouping for matching strings of non-parentheses + is important when applying the pattern to strings that do not match. + For example, when this pattern is applied to + + (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa() + + it yields "no match" quickly. However, if atomic grouping is not used, + the match runs for a very long time indeed because there are so many + different ways the + and * repeats can carve up the subject, and all + have to be tested before failure can be reported. + + At the end of a match, the values set for any capturing subpatterns are + those from the outermost level of the recursion at which the subpattern + value is set. If you want to obtain intermediate values, a callout + function can be used (see the next section and the pcrecallout documen- + tation). If the pattern above is matched against + + (ab(cd)ef) + + the value for the capturing parentheses is "ef", which is the last + value taken on at the top level. If additional parentheses are added, + giving + + \( ( ( (?>[^()]+) | (?R) )* ) \) + ^ ^ + ^ ^ + + the string they capture is "ab(cd)ef", the contents of the top level + parentheses. If there are more than 15 capturing parentheses in a pat- + tern, PCRE has to obtain extra memory to store data during a recursion, + which it does by using pcre_malloc, freeing it via pcre_free after- + wards. If no memory can be obtained, the match fails with the + PCRE_ERROR_NOMEMORY error. + + Do not confuse the (?R) item with the condition (R), which tests for + recursion. Consider this pattern, which matches text in angle brack- + ets, allowing for arbitrary nesting. Only digits are allowed in nested + brackets (that is, when recursing), whereas any characters are permit- + ted at the outer level. + + < (?: (?(R) \d++ | [^<>]*+) | (?R)) * > + + In this pattern, (?(R) is the start of a conditional subpattern, with + two different alternatives for the recursive and non-recursive cases. + The (?R) item is the actual recursive call. + + +SUBPATTERNS AS SUBROUTINES + + If the syntax for a recursive subpattern reference (either by number or + by name) is used outside the parentheses to which it refers, it oper- + ates like a subroutine in a programming language. An earlier example + pointed out that the pattern + + (sens|respons)e and \1ibility + + matches "sense and sensibility" and "response and responsibility", but + not "sense and responsibility". If instead the pattern + + (sens|respons)e and (?1)ibility + + is used, it does match "sense and responsibility" as well as the other + two strings. Such references, if given numerically, must follow the + subpattern to which they refer. However, named references can refer to + later subpatterns. + + Like recursive subpatterns, a "subroutine" call is always treated as an + atomic group. That is, once it has matched some of the subject string, + it is never re-entered, even if it contains untried alternatives and + there is a subsequent matching failure. + + +CALLOUTS + + Perl has a feature whereby using the sequence (?{...}) causes arbitrary + Perl code to be obeyed in the middle of matching a regular expression. + This makes it possible, amongst other things, to extract different sub- + strings that match the same pair of parentheses when there is a repeti- + tion. + + PCRE provides a similar feature, but of course it cannot obey arbitrary + Perl code. The feature is called "callout". The caller of PCRE provides + an external function by putting its entry point in the global variable + pcre_callout. By default, this variable contains NULL, which disables + all calling out. + + Within a regular expression, (?C) indicates the points at which the + external function is to be called. If you want to identify different + callout points, you can put a number less than 256 after the letter C. + The default value is zero. For example, this pattern has two callout + points: + + (?C1)abc(?C2)def + + If the PCRE_AUTO_CALLOUT flag is passed to pcre_compile(), callouts are + automatically installed before each item in the pattern. They are all + numbered 255. + + During matching, when PCRE reaches a callout point (and pcre_callout is + set), the external function is called. It is provided with the number + of the callout, the position in the pattern, and, optionally, one item + of data originally supplied by the caller of pcre_exec(). The callout + function may cause matching to proceed, to backtrack, or to fail alto- + gether. A complete description of the interface to the callout function + is given in the pcrecallout documentation. + +Last updated: 06 June 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + +PCREPARTIAL(3) PCREPARTIAL(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +PARTIAL MATCHING IN PCRE + + In normal use of PCRE, if the subject string that is passed to + pcre_exec() or pcre_dfa_exec() matches as far as it goes, but is too + short to match the entire pattern, PCRE_ERROR_NOMATCH is returned. + There are circumstances where it might be helpful to distinguish this + case from other cases in which there is no match. + + Consider, for example, an application where a human is required to type + in data for a field with specific formatting requirements. An example + might be a date in the form ddmmmyy, defined by this pattern: + + ^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$ + + If the application sees the user's keystrokes one by one, and can check + that what has been typed so far is potentially valid, it is able to + raise an error as soon as a mistake is made, possibly beeping and not + reflecting the character that has been typed. This immediate feedback + is likely to be a better user interface than a check that is delayed + until the entire string has been entered. + + PCRE supports the concept of partial matching by means of the PCRE_PAR- + TIAL option, which can be set when calling pcre_exec() or + pcre_dfa_exec(). When this flag is set for pcre_exec(), the return code + PCRE_ERROR_NOMATCH is converted into PCRE_ERROR_PARTIAL if at any time + during the matching process the last part of the subject string matched + part of the pattern. Unfortunately, for non-anchored matching, it is + not possible to obtain the position of the start of the partial match. + No captured data is set when PCRE_ERROR_PARTIAL is returned. + + When PCRE_PARTIAL is set for pcre_dfa_exec(), the return code + PCRE_ERROR_NOMATCH is converted into PCRE_ERROR_PARTIAL if the end of + the subject is reached, there have been no complete matches, but there + is still at least one matching possibility. The portion of the string + that provided the partial match is set as the first matching string. + + Using PCRE_PARTIAL disables one of PCRE's optimizations. PCRE remembers + the last literal byte in a pattern, and abandons matching immediately + if such a byte is not present in the subject string. This optimization + cannot be used for a subject string that might match only partially. + + +RESTRICTED PATTERNS FOR PCRE_PARTIAL + + Because of the way certain internal optimizations are implemented in + the pcre_exec() function, the PCRE_PARTIAL option cannot be used with + all patterns. These restrictions do not apply when pcre_dfa_exec() is + used. For pcre_exec(), repeated single characters such as + + a{2,4} + + and repeated single metasequences such as + + \d+ + + are not permitted if the maximum number of occurrences is greater than + one. Optional items such as \d? (where the maximum is one) are permit- + ted. Quantifiers with any values are permitted after parentheses, so + the invalid examples above can be coded thus: + + (a){2,4} + (\d)+ + + These constructions run more slowly, but for the kinds of application + that are envisaged for this facility, this is not felt to be a major + restriction. + + If PCRE_PARTIAL is set for a pattern that does not conform to the + restrictions, pcre_exec() returns the error code PCRE_ERROR_BADPARTIAL + (-13). + + +EXAMPLE OF PARTIAL MATCHING USING PCRETEST + + If the escape sequence \P is present in a pcretest data line, the + PCRE_PARTIAL flag is used for the match. Here is a run of pcretest that + uses the date example quoted above: + + re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/ + data> 25jun04\P + 0: 25jun04 + 1: jun + data> 25dec3\P + Partial match + data> 3ju\P + Partial match + data> 3juj\P + No match + data> j\P + No match + + The first data string is matched completely, so pcretest shows the + matched substrings. The remaining four strings do not match the com- + plete pattern, but the first two are partial matches. The same test, + using DFA matching (by means of the \D escape sequence), produces the + following output: + + re> /^?(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)$/ + data> 25jun04\P\D + 0: 25jun04 + data> 23dec3\P\D + Partial match: 23dec3 + data> 3ju\P\D + Partial match: 3ju + data> 3juj\P\D + No match + data> j\P\D + No match + + Notice that in this case the portion of the string that was matched is + made available. + + +MULTI-SEGMENT MATCHING WITH pcre_dfa_exec() + + When a partial match has been found using pcre_dfa_exec(), it is possi- + ble to continue the match by providing additional subject data and + calling pcre_dfa_exec() again with the PCRE_DFA_RESTART option and the + same working space (where details of the previous partial match are + stored). Here is an example using pcretest, where the \R escape + sequence sets the PCRE_DFA_RESTART option and the \D escape sequence + requests the use of pcre_dfa_exec(): + + re> /^?(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)$/ + data> 23ja\P\D + Partial match: 23ja + data> n05\R\D + 0: n05 + + The first call has "23ja" as the subject, and requests partial match- + ing; the second call has "n05" as the subject for the continued + (restarted) match. Notice that when the match is complete, only the + last part is shown; PCRE does not retain the previously partially- + matched string. It is up to the calling program to do that if it needs + to. + + This facility can be used to pass very long subject strings to + pcre_dfa_exec(). However, some care is needed for certain types of pat- + tern. + + 1. If the pattern contains tests for the beginning or end of a line, + you need to pass the PCRE_NOTBOL or PCRE_NOTEOL options, as appropri- + ate, when the subject string for any call does not contain the begin- + ning or end of a line. + + 2. If the pattern contains backward assertions (including \b or \B), + you need to arrange for some overlap in the subject strings to allow + for this. For example, you could pass the subject in chunks that were + 500 bytes long, but in a buffer of 700 bytes, with the starting offset + set to 200 and the previous 200 bytes at the start of the buffer. + + 3. Matching a subject string that is split into multiple segments does + not always produce exactly the same result as matching over one single + long string. The difference arises when there are multiple matching + possibilities, because a partial match result is given only when there + are no completed matches in a call to fBpcre_dfa_exec(). This means + that as soon as the shortest match has been found, continuation to a + new subject segment is no longer possible. Consider this pcretest + example: + + re> /dog(sbody)?/ + data> do\P\D + Partial match: do + data> gsb\R\P\D + 0: g + data> dogsbody\D + 0: dogsbody + 1: dog + + The pattern matches the words "dog" or "dogsbody". When the subject is + presented in several parts ("do" and "gsb" being the first two) the + match stops when "dog" has been found, and it is not possible to con- + tinue. On the other hand, if "dogsbody" is presented as a single + string, both matches are found. + + Because of this phenomenon, it does not usually make sense to end a + pattern that is going to be matched in this way with a variable repeat. + + 4. Patterns that contain alternatives at the top level which do not all + start with the same pattern item may not work as expected. For example, + consider this pattern: + + 1234|3789 + + If the first part of the subject is "ABC123", a partial match of the + first alternative is found at offset 3. There is no partial match for + the second alternative, because such a match does not start at the same + point in the subject string. Attempting to continue with the string + "789" does not yield a match because only those alternatives that match + at one point in the subject are remembered. The problem arises because + the start of the second alternative matches within the first alterna- + tive. There is no problem with anchored patterns or patterns such as: + + 1234|ABCD + + where no string can be a partial match for both alternatives. + +Last updated: 16 January 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + +PCREPRECOMPILE(3) PCREPRECOMPILE(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +SAVING AND RE-USING PRECOMPILED PCRE PATTERNS + + If you are running an application that uses a large number of regular + expression patterns, it may be useful to store them in a precompiled + form instead of having to compile them every time the application is + run. If you are not using any private character tables (see the + pcre_maketables() documentation), this is relatively straightforward. + If you are using private tables, it is a little bit more complicated. + + If you save compiled patterns to a file, you can copy them to a differ- + ent host and run them there. This works even if the new host has the + opposite endianness to the one on which the patterns were compiled. + There may be a small performance penalty, but it should be insignifi- + cant. + + +SAVING A COMPILED PATTERN + The value returned by pcre_compile() points to a single block of memory + that holds the compiled pattern and associated data. You can find the + length of this block in bytes by calling pcre_fullinfo() with an argu- + ment of PCRE_INFO_SIZE. You can then save the data in any appropriate + manner. Here is sample code that compiles a pattern and writes it to a + file. It assumes that the variable fd refers to a file that is open for + output: + + int erroroffset, rc, size; + char *error; + pcre *re; + + re = pcre_compile("my pattern", 0, &error, &erroroffset, NULL); + if (re == NULL) { ... handle errors ... } + rc = pcre_fullinfo(re, NULL, PCRE_INFO_SIZE, &size); + if (rc < 0) { ... handle errors ... } + rc = fwrite(re, 1, size, fd); + if (rc != size) { ... handle errors ... } + + In this example, the bytes that comprise the compiled pattern are + copied exactly. Note that this is binary data that may contain any of + the 256 possible byte values. On systems that make a distinction + between binary and non-binary data, be sure that the file is opened for + binary output. + + If you want to write more than one pattern to a file, you will have to + devise a way of separating them. For binary data, preceding each pat- + tern with its length is probably the most straightforward approach. + Another possibility is to write out the data in hexadecimal instead of + binary, one pattern to a line. + + Saving compiled patterns in a file is only one possible way of storing + them for later use. They could equally well be saved in a database, or + in the memory of some daemon process that passes them via sockets to + the processes that want them. + + If the pattern has been studied, it is also possible to save the study + data in a similar way to the compiled pattern itself. When studying + generates additional information, pcre_study() returns a pointer to a + pcre_extra data block. Its format is defined in the section on matching + a pattern in the pcreapi documentation. The study_data field points to + the binary study data, and this is what you must save (not the + pcre_extra block itself). The length of the study data can be obtained + by calling pcre_fullinfo() with an argument of PCRE_INFO_STUDYSIZE. + Remember to check that pcre_study() did return a non-NULL value before + trying to save the study data. + + +RE-USING A PRECOMPILED PATTERN + + Re-using a precompiled pattern is straightforward. Having reloaded it + into main memory, you pass its pointer to pcre_exec() or + pcre_dfa_exec() in the usual way. This should work even on another + host, and even if that host has the opposite endianness to the one + where the pattern was compiled. + + However, if you passed a pointer to custom character tables when the + pattern was compiled (the tableptr argument of pcre_compile()), you + must now pass a similar pointer to pcre_exec() or pcre_dfa_exec(), + because the value saved with the compiled pattern will obviously be + nonsense. A field in a pcre_extra() block is used to pass this data, as + described in the section on matching a pattern in the pcreapi documen- + tation. + + If you did not provide custom character tables when the pattern was + compiled, the pointer in the compiled pattern is NULL, which causes + pcre_exec() to use PCRE's internal tables. Thus, you do not need to + take any special action at run time in this case. + + If you saved study data with the compiled pattern, you need to create + your own pcre_extra data block and set the study_data field to point to + the reloaded study data. You must also set the PCRE_EXTRA_STUDY_DATA + bit in the flags field to indicate that study data is present. Then + pass the pcre_extra block to pcre_exec() or pcre_dfa_exec() in the + usual way. + + +COMPATIBILITY WITH DIFFERENT PCRE RELEASES + + The layout of the control block that is at the start of the data that + makes up a compiled pattern was changed for release 5.0. If you have + any saved patterns that were compiled with previous releases (not a + facility that was previously advertised), you will have to recompile + them for release 5.0. However, from now on, it should be possible to + make changes in a compatible manner. + + Notwithstanding the above, if you have any saved patterns in UTF-8 mode + that use \p or \P that were compiled with any release up to and includ- + ing 6.4, you will have to recompile them for release 6.5 and above. + +Last updated: 01 February 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + +PCREPERFORM(3) PCREPERFORM(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +PCRE PERFORMANCE + + Certain items that may appear in regular expression patterns are more + efficient than others. It is more efficient to use a character class + like [aeiou] than a set of alternatives such as (a|e|i|o|u). In gen- + eral, the simplest construction that provides the required behaviour is + usually the most efficient. Jeffrey Friedl's book contains a lot of + useful general discussion about optimizing regular expressions for + efficient performance. This document contains a few observations about + PCRE. + + Using Unicode character properties (the \p, \P, and \X escapes) is + slow, because PCRE has to scan a structure that contains data for over + fifteen thousand characters whenever it needs a character's property. + If you can find an alternative pattern that does not use character + properties, it will probably be faster. + + When a pattern begins with .* not in parentheses, or in parentheses + that are not the subject of a backreference, and the PCRE_DOTALL option + is set, the pattern is implicitly anchored by PCRE, since it can match + only at the start of a subject string. However, if PCRE_DOTALL is not + set, PCRE cannot make this optimization, because the . metacharacter + does not then match a newline, and if the subject string contains new- + lines, the pattern may match from the character immediately following + one of them instead of from the very start. For example, the pattern + + .*second + + matches the subject "first\nand second" (where \n stands for a newline + character), with the match starting at the seventh character. In order + to do this, PCRE has to retry the match starting after every newline in + the subject. + + If you are using such a pattern with subject strings that do not con- + tain newlines, the best performance is obtained by setting PCRE_DOTALL, + or starting the pattern with ^.* or ^.*? to indicate explicit anchor- + ing. That saves PCRE from having to scan along the subject looking for + a newline to restart at. + + Beware of patterns that contain nested indefinite repeats. These can + take a long time to run when applied to a string that does not match. + Consider the pattern fragment + + (a+)* + + This can match "aaaa" in 33 different ways, and this number increases + very rapidly as the string gets longer. (The * repeat can match 0, 1, + 2, 3, or 4 times, and for each of those cases other than 0, the + + repeats can match different numbers of times.) When the remainder of + the pattern is such that the entire match is going to fail, PCRE has in + principle to try every possible variation, and this can take an + extremely long time. + + An optimization catches some of the more simple cases such as + + (a+)*b + + where a literal character follows. Before embarking on the standard + matching procedure, PCRE checks that there is a "b" later in the sub- + ject string, and if there is not, it fails the match immediately. How- + ever, when there is no following literal this optimization cannot be + used. You can see the difference by comparing the behaviour of + + (a+)*\d + + with the pattern above. The former gives a failure almost instantly + when applied to a whole line of "a" characters, whereas the latter + takes an appreciable time with strings longer than about 20 characters. + + In many cases, the solution to this kind of performance issue is to use + an atomic group or a possessive quantifier. + +Last updated: 28 February 2005 +Copyright (c) 1997-2005 University of Cambridge. +------------------------------------------------------------------------------ + + +PCREPOSIX(3) PCREPOSIX(3) + + +NAME + PCRE - Perl-compatible regular expressions. + + +SYNOPSIS OF POSIX API + + #include <pcreposix.h> + + int regcomp(regex_t *preg, const char *pattern, + int cflags); + + int regexec(regex_t *preg, const char *string, + size_t nmatch, regmatch_t pmatch[], int eflags); + + size_t regerror(int errcode, const regex_t *preg, + char *errbuf, size_t errbuf_size); + + void regfree(regex_t *preg); + + +DESCRIPTION + + This set of functions provides a POSIX-style API to the PCRE regular + expression package. See the pcreapi documentation for a description of + PCRE's native API, which contains much additional functionality. + + The functions described here are just wrapper functions that ultimately + call the PCRE native API. Their prototypes are defined in the + pcreposix.h header file, and on Unix systems the library itself is + called pcreposix.a, so can be accessed by adding -lpcreposix to the + command for linking an application that uses them. Because the POSIX + functions call the native ones, it is also necessary to add -lpcre. + + I have implemented only those option bits that can be reasonably mapped + to PCRE native options. In addition, the option REG_EXTENDED is defined + with the value zero. This has no effect, but since programs that are + written to the POSIX interface often use it, this makes it easier to + slot in PCRE as a replacement library. Other POSIX options are not even + defined. + + When PCRE is called via these functions, it is only the API that is + POSIX-like in style. The syntax and semantics of the regular expres- + sions themselves are still those of Perl, subject to the setting of + various PCRE options, as described below. "POSIX-like in style" means + that the API approximates to the POSIX definition; it is not fully + POSIX-compatible, and in multi-byte encoding domains it is probably + even less compatible. + + The header for these functions is supplied as pcreposix.h to avoid any + potential clash with other POSIX libraries. It can, of course, be + renamed or aliased as regex.h, which is the "correct" name. It provides + two structure types, regex_t for compiled internal forms, and reg- + match_t for returning captured substrings. It also defines some con- + stants whose names start with "REG_"; these are used for setting + options and identifying error codes. + + +COMPILING A PATTERN + + The function regcomp() is called to compile a pattern into an internal + form. The pattern is a C string terminated by a binary zero, and is + passed in the argument pattern. The preg argument is a pointer to a + regex_t structure that is used as a base for storing information about + the compiled regular expression. + + The argument cflags is either zero, or contains one or more of the bits + defined by the following macros: + + REG_DOTALL + + The PCRE_DOTALL option is set when the regular expression is passed for + compilation to the native function. Note that REG_DOTALL is not part of + the POSIX standard. + + REG_ICASE + + The PCRE_CASELESS option is set when the regular expression is passed + for compilation to the native function. + + REG_NEWLINE + + The PCRE_MULTILINE option is set when the regular expression is passed + for compilation to the native function. Note that this does not mimic + the defined POSIX behaviour for REG_NEWLINE (see the following sec- + tion). + + REG_NOSUB + + The PCRE_NO_AUTO_CAPTURE option is set when the regular expression is + passed for compilation to the native function. In addition, when a pat- + tern that is compiled with this flag is passed to regexec() for match- + ing, the nmatch and pmatch arguments are ignored, and no captured + strings are returned. + + REG_UTF8 + + The PCRE_UTF8 option is set when the regular expression is passed for + compilation to the native function. This causes the pattern itself and + all data strings used for matching it to be treated as UTF-8 strings. + Note that REG_UTF8 is not part of the POSIX standard. + + In the absence of these flags, no options are passed to the native + function. This means the the regex is compiled with PCRE default + semantics. In particular, the way it handles newline characters in the + subject string is the Perl way, not the POSIX way. Note that setting + PCRE_MULTILINE has only some of the effects specified for REG_NEWLINE. + It does not affect the way newlines are matched by . (they aren't) or + by a negative class such as [^a] (they are). + + The yield of regcomp() is zero on success, and non-zero otherwise. The + preg structure is filled in on success, and one member of the structure + is public: re_nsub contains the number of capturing subpatterns in the + regular expression. Various error codes are defined in the header file. + + +MATCHING NEWLINE CHARACTERS + + This area is not simple, because POSIX and Perl take different views of + things. It is not possible to get PCRE to obey POSIX semantics, but + then PCRE was never intended to be a POSIX engine. The following table + lists the different possibilities for matching newline characters in + PCRE: + + Default Change with + + . matches newline no PCRE_DOTALL + newline matches [^a] yes not changeable + $ matches \n at end yes PCRE_DOLLARENDONLY + $ matches \n in middle no PCRE_MULTILINE + ^ matches \n in middle no PCRE_MULTILINE + + This is the equivalent table for POSIX: + + Default Change with + + . matches newline yes REG_NEWLINE + newline matches [^a] yes REG_NEWLINE + $ matches \n at end no REG_NEWLINE + $ matches \n in middle no REG_NEWLINE + ^ matches \n in middle no REG_NEWLINE + + PCRE's behaviour is the same as Perl's, except that there is no equiva- + lent for PCRE_DOLLAR_ENDONLY in Perl. In both PCRE and Perl, there is + no way to stop newline from matching [^a]. + + The default POSIX newline handling can be obtained by setting + PCRE_DOTALL and PCRE_DOLLAR_ENDONLY, but there is no way to make PCRE + behave exactly as for the REG_NEWLINE action. + + +MATCHING A PATTERN + + The function regexec() is called to match a compiled pattern preg + against a given string, which is terminated by a zero byte, subject to + the options in eflags. These can be: + + REG_NOTBOL + + The PCRE_NOTBOL option is set when calling the underlying PCRE matching + function. + + REG_NOTEOL + + The PCRE_NOTEOL option is set when calling the underlying PCRE matching + function. + + If the pattern was compiled with the REG_NOSUB flag, no data about any + matched strings is returned. The nmatch and pmatch arguments of + regexec() are ignored. + + Otherwise,the portion of the string that was matched, and also any cap- + tured substrings, are returned via the pmatch argument, which points to + an array of nmatch structures of type regmatch_t, containing the mem- + bers rm_so and rm_eo. These contain the offset to the first character + of each substring and the offset to the first character after the end + of each substring, respectively. The 0th element of the vector relates + to the entire portion of string that was matched; subsequent elements + relate to the capturing subpatterns of the regular expression. Unused + entries in the array have both structure members set to -1. + + A successful match yields a zero return; various error codes are + defined in the header file, of which REG_NOMATCH is the "expected" + failure code. + + +ERROR MESSAGES + + The regerror() function maps a non-zero errorcode from either regcomp() + or regexec() to a printable message. If preg is not NULL, the error + should have arisen from the use of that structure. A message terminated + by a binary zero is placed in errbuf. The length of the message, + including the zero, is limited to errbuf_size. The yield of the func- + tion is the size of buffer needed to hold the whole message. + + +MEMORY USAGE + + Compiling a regular expression causes memory to be allocated and asso- + ciated with the preg structure. The function regfree() frees all such + memory, after which preg may no longer be used as a compiled expres- + sion. + + +AUTHOR + + Philip Hazel + University Computing Service, + Cambridge CB2 3QG, England. + +Last updated: 16 January 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + +PCRECPP(3) PCRECPP(3) + + +NAME + PCRE - Perl-compatible regular expressions. + + +SYNOPSIS OF C++ WRAPPER + + #include <pcrecpp.h> + + +DESCRIPTION + + The C++ wrapper for PCRE was provided by Google Inc. Some additional + functionality was added by Giuseppe Maxia. This brief man page was con- + structed from the notes in the pcrecpp.h file, which should be con- + sulted for further details. + + +MATCHING INTERFACE + + The "FullMatch" operation checks that supplied text matches a supplied + pattern exactly. If pointer arguments are supplied, it copies matched + sub-strings that match sub-patterns into them. + + Example: successful match + pcrecpp::RE re("h.*o"); + re.FullMatch("hello"); + + Example: unsuccessful match (requires full match): + pcrecpp::RE re("e"); + !re.FullMatch("hello"); + + Example: creating a temporary RE object: + pcrecpp::RE("h.*o").FullMatch("hello"); + + You can pass in a "const char*" or a "string" for "text". The examples + below tend to use a const char*. You can, as in the different examples + above, store the RE object explicitly in a variable or use a temporary + RE object. The examples below use one mode or the other arbitrarily. + Either could correctly be used for any of these examples. + + You must supply extra pointer arguments to extract matched subpieces. + + Example: extracts "ruby" into "s" and 1234 into "i" + int i; + string s; + pcrecpp::RE re("(\\w+):(\\d+)"); + re.FullMatch("ruby:1234", &s, &i); + + Example: does not try to extract any extra sub-patterns + re.FullMatch("ruby:1234", &s); + + Example: does not try to extract into NULL + re.FullMatch("ruby:1234", NULL, &i); + + Example: integer overflow causes failure + !re.FullMatch("ruby:1234567891234", NULL, &i); + + Example: fails because there aren't enough sub-patterns: + !pcrecpp::RE("\\w+:\\d+").FullMatch("ruby:1234", &s); + + Example: fails because string cannot be stored in integer + !pcrecpp::RE("(.*)").FullMatch("ruby", &i); + + The provided pointer arguments can be pointers to any scalar numeric + type, or one of: + + string (matched piece is copied to string) + StringPiece (StringPiece is mutated to point to matched piece) + T (where "bool T::ParseFrom(const char*, int)" exists) + NULL (the corresponding matched sub-pattern is not copied) + + The function returns true iff all of the following conditions are sat- + isfied: + + a. "text" matches "pattern" exactly; + + b. The number of matched sub-patterns is >= number of supplied + pointers; + + c. The "i"th argument has a suitable type for holding the + string captured as the "i"th sub-pattern. If you pass in + NULL for the "i"th argument, or pass fewer arguments than + number of sub-patterns, "i"th captured sub-pattern is + ignored. + + The matching interface supports at most 16 arguments per call. If you + need more, consider using the more general interface + pcrecpp::RE::DoMatch. See pcrecpp.h for the signature for DoMatch. + + +PARTIAL MATCHES + + You can use the "PartialMatch" operation when you want the pattern to + match any substring of the text. + + Example: simple search for a string: + pcrecpp::RE("ell").PartialMatch("hello"); + + Example: find first number in a string: + int number; + pcrecpp::RE re("(\\d+)"); + re.PartialMatch("x*100 + 20", &number); + assert(number == 100); + + +UTF-8 AND THE MATCHING INTERFACE + + By default, pattern and text are plain text, one byte per character. + The UTF8 flag, passed to the constructor, causes both pattern and + string to be treated as UTF-8 text, still a byte stream but potentially + multiple bytes per character. In practice, the text is likelier to be + UTF-8 than the pattern, but the match returned may depend on the UTF8 + flag, so always use it when matching UTF8 text. For example, "." will + match one byte normally but with UTF8 set may match up to three bytes + of a multi-byte character. + + Example: + pcrecpp::RE_Options options; + options.set_utf8(); + pcrecpp::RE re(utf8_pattern, options); + re.FullMatch(utf8_string); + + Example: using the convenience function UTF8(): + pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8()); + re.FullMatch(utf8_string); + + NOTE: The UTF8 flag is ignored if pcre was not configured with the + --enable-utf8 flag. + + +PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE + + PCRE defines some modifiers to change the behavior of the regular + expression engine. The C++ wrapper defines an auxiliary class, + RE_Options, as a vehicle to pass such modifiers to a RE class. Cur- + rently, the following modifiers are supported: + + modifier description Perl corresponding + + PCRE_CASELESS case insensitive match /i + PCRE_MULTILINE multiple lines match /m + PCRE_DOTALL dot matches newlines /s + PCRE_DOLLAR_ENDONLY $ matches only at end N/A + PCRE_EXTRA strict escape parsing N/A + PCRE_EXTENDED ignore whitespaces /x + PCRE_UTF8 handles UTF8 chars built-in + PCRE_UNGREEDY reverses * and *? N/A + PCRE_NO_AUTO_CAPTURE disables capturing parens N/A (*) + + (*) Both Perl and PCRE allow non capturing parentheses by means of the + "?:" modifier within the pattern itself. e.g. (?:ab|cd) does not cap- + ture, while (ab|cd) does. + + For a full account on how each modifier works, please check the PCRE + API reference page. + + For each modifier, there are two member functions whose name is made + out of the modifier in lowercase, without the "PCRE_" prefix. For + instance, PCRE_CASELESS is handled by + + bool caseless() + + which returns true if the modifier is set, and + + RE_Options & set_caseless(bool) + + which sets or unsets the modifier. Moreover, PCRE_EXTRA_MATCH_LIMIT can + be accessed through the set_match_limit() and match_limit() member + functions. Setting match_limit to a non-zero value will limit the exe- + cution of pcre to keep it from doing bad things like blowing the stack + or taking an eternity to return a result. A value of 5000 is good + enough to stop stack blowup in a 2MB thread stack. Setting match_limit + to zero disables match limiting. Alternatively, you can call + match_limit_recursion() which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to + limit how much PCRE recurses. match_limit() limits the number of + matches PCRE does; match_limit_recursion() limits the depth of internal + recursion, and therefore the amount of stack that is used. + + Normally, to pass one or more modifiers to a RE class, you declare a + RE_Options object, set the appropriate options, and pass this object to + a RE constructor. Example: + + RE_options opt; + opt.set_caseless(true); + if (RE("HELLO", opt).PartialMatch("hello world")) ... + + RE_options has two constructors. The default constructor takes no argu- + ments and creates a set of flags that are off by default. The optional + parameter option_flags is to facilitate transfer of legacy code from C + programs. This lets you do + + RE(pattern, + RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str); + + However, new code is better off doing + + RE(pattern, + RE_Options().set_caseless(true).set_multiline(true)) + .PartialMatch(str); + + If you are going to pass one of the most used modifiers, there are some + convenience functions that return a RE_Options class with the appropri- + ate modifier already set: CASELESS(), UTF8(), MULTILINE(), DOTALL(), + and EXTENDED(). + + If you need to set several options at once, and you don't want to go + through the pains of declaring a RE_Options object and setting several + options, there is a parallel method that give you such ability on the + fly. You can concatenate several set_xxxxx() member functions, since + each of them returns a reference to its class object. For example, to + pass PCRE_CASELESS, PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one + statement, you may write: + + RE(" ^ xyz \\s+ .* blah$", + RE_Options() + .set_caseless(true) + .set_extended(true) + .set_multiline(true)).PartialMatch(sometext); + + +SCANNING TEXT INCREMENTALLY + + The "Consume" operation may be useful if you want to repeatedly match + regular expressions at the front of a string and skip over them as they + match. This requires use of the "StringPiece" type, which represents a + sub-range of a real string. Like RE, StringPiece is defined in the + pcrecpp namespace. + + Example: read lines of the form "var = value" from a string. + string contents = ...; // Fill string somehow + pcrecpp::StringPiece input(contents); // Wrap in a StringPiece + + string var; + int value; + pcrecpp::RE re("(\\w+) = (\\d+)\n"); + while (re.Consume(&input, &var, &value)) { + ...; + } + + Each successful call to "Consume" will set "var/value", and also + advance "input" so it points past the matched text. + + The "FindAndConsume" operation is similar to "Consume" but does not + anchor your match at the beginning of the string. For example, you + could extract all words from a string by repeatedly calling + + pcrecpp::RE("(\\w+)").FindAndConsume(&input, &word) + + +PARSING HEX/OCTAL/C-RADIX NUMBERS + + By default, if you pass a pointer to a numeric value, the corresponding + text is interpreted as a base-10 number. You can instead wrap the + pointer with a call to one of the operators Hex(), Octal(), or CRadix() + to interpret the text in another base. The CRadix operator interprets + C-style "0" (base-8) and "0x" (base-16) prefixes, but defaults to + base-10. + + Example: + int a, b, c, d; + pcrecpp::RE re("(.*) (.*) (.*) (.*)"); + re.FullMatch("100 40 0100 0x40", + pcrecpp::Octal(&a), pcrecpp::Hex(&b), + pcrecpp::CRadix(&c), pcrecpp::CRadix(&d)); + + will leave 64 in a, b, c, and d. + + +REPLACING PARTS OF STRINGS + + You can replace the first match of "pattern" in "str" with "rewrite". + Within "rewrite", backslash-escaped digits (\1 to \9) can be used to + insert text matching corresponding parenthesized group from the pat- + tern. \0 in "rewrite" refers to the entire matching text. For example: + + string s = "yabba dabba doo"; + pcrecpp::RE("b+").Replace("d", &s); + + will leave "s" containing "yada dabba doo". The result is true if the + pattern matches and a replacement occurs, false otherwise. + + GlobalReplace is like Replace except that it replaces all occurrences + of the pattern in the string with the rewrite. Replacements are not + subject to re-matching. For example: + + string s = "yabba dabba doo"; + pcrecpp::RE("b+").GlobalReplace("d", &s); + + will leave "s" containing "yada dada doo". It returns the number of + replacements made. + + Extract is like Replace, except that if the pattern matches, "rewrite" + is copied into "out" (an additional argument) with substitutions. The + non-matching portions of "text" are ignored. Returns true iff a match + occurred and the extraction happened successfully; if no match occurs, + the string is left unaffected. + + +AUTHOR + + The C++ wrapper was contributed by Google Inc. + Copyright (c) 2005 Google Inc. +------------------------------------------------------------------------------ + + +PCRESAMPLE(3) PCRESAMPLE(3) + + +NAME + PCRE - Perl-compatible regular expressions + + +PCRE SAMPLE PROGRAM + + A simple, complete demonstration program, to get you started with using + PCRE, is supplied in the file pcredemo.c in the PCRE distribution. + + The program compiles the regular expression that is its first argument, + and matches it against the subject string in its second argument. No + PCRE options are set, and default character tables are used. If match- + ing succeeds, the program outputs the portion of the subject that + matched, together with the contents of any captured substrings. + + If the -g option is given on the command line, the program then goes on + to check for further matches of the same regular expression in the same + subject string. The logic is a little bit tricky because of the possi- + bility of matching an empty string. Comments in the code explain what + is going on. + + If PCRE is installed in the standard include and library directories + for your system, you should be able to compile the demonstration pro- + gram using this command: + + gcc -o pcredemo pcredemo.c -lpcre + + If PCRE is installed elsewhere, you may need to add additional options + to the command line. For example, on a Unix-like system that has PCRE + installed in /usr/local, you can compile the demonstration program + using a command like this: + + gcc -o pcredemo -I/usr/local/include pcredemo.c \ + -L/usr/local/lib -lpcre + + Once you have compiled the demonstration program, you can run simple + tests like this: + + ./pcredemo 'cat|dog' 'the cat sat on the mat' + ./pcredemo -g 'cat|dog' 'the dog sat on the cat' + + Note that there is a much more comprehensive test program, called + pcretest, which supports many more facilities for testing regular + expressions and the PCRE library. The pcredemo program is provided as a + simple coding example. + + On some operating systems (e.g. Solaris), when PCRE is not installed in + the standard library directory, you may get an error like this when you + try to run pcredemo: + + ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or + directory + + This is caused by the way shared library support works on those sys- + tems.

This calls itself recursively at branch points in the pattern, + in order to remember the state of the match so that it can back up and + try a different alternative if the first one fails. As matching pro- + ceeds deeper and deeper into the tree of possibilities, the recursion + depth increases. + + Not all calls of match() increase the recursion depth; for an item such + as a* it may be called several times at the same level, after matching + different numbers of a's. Furthermore, in a number of cases where the + result of the recursive call would immediately be passed back as the + result of the current call (a "tail recursion"), the function is just + restarted instead. + + The pcre_dfa_exec() function operates in an entirely different way, and + hardly uses recursion at all. The limit on its complexity is the amount + of workspace it is given. The comments that follow do NOT apply to + pcre_dfa_exec(); they are relevant only for pcre_exec(). + + You can set limits on the number of times that match() is called, both + in total and recursively. If the limit is exceeded, an error occurs. + For details, see the section on extra data for pcre_exec() in the + pcreapi documentation. + + Each time that match() is actually called recursively, it uses memory + from the process stack. For certain kinds of pattern and data, very + large amounts of stack may be needed, despite the recognition of "tail + recursion". You can often reduce the amount of recursion, and there- + fore the amount of stack used, by modifying the pattern that is being + matched. Consider, for example, this pattern: + + ([^<]|<(?!inet))+ + + It matches from wherever it starts until it encounters "<inet" or the + end of the data, and is the kind of pattern that might be used when + processing an XML file. Each iteration of the outer parentheses matches + either one character that is not "<" or a "<" that is not followed by + "inet". However, each time a parenthesis is processed, a recursion + occurs, so this formulation uses a stack frame for each matched charac- + ter. For a long string, a lot of stack is required. Consider now this + rewritten pattern, which matches exactly the same strings: + + ([^<]++|<(?!inet)) + + This uses very much less stack, because runs of characters that do not + contain "<" are "swallowed" in one item inside the parentheses. Recur- + sion happens only when a "<" character that is not followed by "inet" + is encountered (and we assume this is relatively rare). A possessive + quantifier is used to stop any backtracking into the runs of non-"<" + characters, but that is not related to stack usage. + + In environments where stack memory is constrained, you might want to + compile PCRE to use heap memory instead of stack for remembering back- + up points. This makes it run a lot more slowly, however. Details of how + to do this are given in the pcrebuild documentation. + + In Unix-like environments, there is not often a problem with the stack, + though the default limit on stack size varies from system to system. + Values from 8Mb to 64Mb are common. You can find your default limit by + running the command: + + ulimit -s + + The effect of running out of stack is often SIGSEGV, though sometimes + an error message is given. You can normally increase the limit on stack + size by code such as this: + + struct rlimit rlim; + getrlimit(RLIMIT_STACK, &rlim); + rlim.rlim_cur = 100*1024*1024; + setrlimit(RLIMIT_STACK, &rlim); + + This reads the current limits (soft and hard) using getrlimit(), then + attempts to increase the soft limit to 100Mb using setrlimit(). You + must do this before calling pcre_exec(). + + PCRE has an internal counter that can be used to limit the depth of + recursion, and thus cause pcre_exec() to give an error code before it + runs out of stack. By default, the limit is very large, and unlikely + ever to operate. It can be changed when PCRE is built, and it can also + be set when pcre_exec() is called. For details of these interfaces, see + the pcrebuild and pcreapi documentation. + + As a very rough rule of thumb, you should reckon on about 500 bytes per + recursion. Thus, if you want to limit your stack usage to 8Mb, you + should set the limit at 16000 recursions. A 64Mb stack, on the other + hand, can support around 128000 recursions. The pcretest test program + has a command line option (-S) that can be used to increase its stack. + +Last updated: 29 June 2006 +Copyright (c) 1997-2006 University of Cambridge. +------------------------------------------------------------------------------ + + Added: freeswitch/trunk/libs/pcre/doc/pcre_compile.3 ============================================================================== --- (empty file) +++ freeswitch/trunk/libs/pcre/doc/pcre_compile.3 Tue Dec 19 14:54:26 2006 @@ -0,0 +1,69 @@ +.TH PCRE_COMPILE 3 +.SH NAME +PCRE - Perl-compatible regular expressions +.SH SYNOPSIS +.rs +.sp +.B #include <pcre.h> +.PP +.SM +.br +.B pcre *pcre_compile(const char *\fIpattern\fP, int \fIoptions\fP, +.ti +5n +.B const char **\fIerrptr\fP, int *\fIerroffset\fP, +.ti +5n +.B const unsigned char *\fItableptr\fP); +. +.SH DESCRIPTION +.rs +.sp +This function compiles a regular expression into an internal form.

There is +also a set of wrapper functions that correspond to the POSIX regular expression +API. These are described in the +.\" HREF +\fBpcreposix\fP +.\" +documentation. Both of these APIs define a set of C function calls. A C++ +wrapper is distributed with PCRE. It is documented in the +.\" HREF +\fBpcrecpp\fP +.\" +page. +.P +The native API C function prototypes are defined in the header file +\fBpcre.h\fP, and on Unix systems the library itself is called \fBlibpcre\fP. +It can normally be accessed by adding \fB-lpcre\fP to the command for linking +an application that uses PCRE. The header file defines the macros PCRE_MAJOR +and PCRE_MINOR to contain the major and minor release numbers for the library. +Applications can use these to include support for different releases of PCRE. +.P +The functions \fBpcre_compile()\fP, \fBpcre_compile2()\fP, \fBpcre_study()\fP, +and \fBpcre_exec()\fP are used for compiling and matching regular expressions +in a Perl-compatible manner. A sample program that demonstrates the simplest +way of using them is provided in the file called \fIpcredemo.c\fP in the source +distribution. The +.\" HREF +\fBpcresample\fP +.\" +documentation describes how to run it. +.P +A second matching function, \fBpcre_dfa_exec()\fP, which is not +Perl-compatible, is also provided. This uses a different algorithm for the +matching. The alternative algorithm finds all possible matches (at a given +point in the subject). However, this algorithm does not return captured +substrings. A description of the two matching algorithms and their advantages +and disadvantages is given in the +.\" HREF +\fBpcrematching\fP +.\" +documentation. +.P +In addition to the main compiling and matching functions, there are convenience +functions for extracting captured substrings from a subject string that is +matched by \fBpcre_exec()\fP. They are: +.sp + \fBpcre_copy_substring()\fP + \fBpcre_copy_named_substring()\fP + \fBpcre_get_substring()\fP + \fBpcre_get_named_substring()\fP + \fBpcre_get_substring_list()\fP + \fBpcre_get_stringnumber()\fP + \fBpcre_get_stringtable_entries()\fP +.sp +\fBpcre_free_substring()\fP and \fBpcre_free_substring_list()\fP are also +provided, to free the memory used for extracted strings. +.P +The function \fBpcre_maketables()\fP is used to build a set of character tables +in the current locale for passing to \fBpcre_compile()\fP, \fBpcre_exec()\fP, +or \fBpcre_dfa_exec()\fP. This is an optional facility that is provided for +specialist use. Most commonly, no special tables are passed, in which case +internal tables that are generated when PCRE is built are used. +.P +The function \fBpcre_fullinfo()\fP is used to find out information about a +compiled pattern; \fBpcre_info()\fP is an obsolete version that returns only +some of the available information, but is retained for backwards compatibility. +The function \fBpcre_version()\fP returns a pointer to a string containing the +version of PCRE and its date of release. +.P +The function \fBpcre_refcount()\fP maintains a reference count in a data block +containing a compiled pattern. This is provided for the benefit of +object-oriented applications. +.P +The global variables \fBpcre_malloc\fP and \fBpcre_free\fP initially contain +the entry points of the standard \fBmalloc()\fP and \fBfree()\fP functions, +respectively. PCRE calls the memory management functions via these variables, +so a calling program can replace them if it wishes to intercept the calls. This +should be done before calling any PCRE functions. +.P +The global variables \fBpcre_stack_malloc\fP and \fBpcre_stack_free\fP are also +indirections to memory management functions. These special functions are used +only when PCRE is compiled to use the heap for remembering data, instead of +recursive function calls, when running the \fBpcre_exec()\fP function. See the +.\" HREF +\fBpcrebuild\fP +.\" +documentation for details of how to do this. It is a non-standard way of +building PCRE, for use in environments that have limited stacks. Because of the +greater use of memory management, it runs more slowly. Separate functions are +provided so that special-purpose external code can be used for this case. When +used, these functions are always called in a stack-like manner (last obtained, +first freed), and always for memory blocks of the same size. There is a +discussion about PCRE's stack usage in the +.\" HREF +\fBpcrestack\fP +.\" +documentation. +.P +The global variable \fBpcre_callout\fP initially contains NULL. It can be set +by the caller to a "callout" function, which PCRE will then call at specified +points during a matching operation. Details are given in the +.\" HREF +\fBpcrecallout\fP +.\" +documentation. +. +. +.SH NEWLINES +PCRE supports three different conventions for indicating line breaks in +strings: a single CR character, a single LF character, or the two-character +sequence CRLF. All three are used as "standard" by different operating systems. +When PCRE is built, a default can be specified. The default default is LF, +which is the Unix standard. When PCRE is run, the default can be overridden, +either when a pattern is compiled, or when it is matched. +.sp +In the PCRE documentation the word "newline" is used to mean "the character or +pair of characters that indicate a line break". +. +. +.SH MULTITHREADING +.rs +.sp +The PCRE functions can be used in multi-threading applications, with the +proviso that the memory management functions pointed to by \fBpcre_malloc\fP, +\fBpcre_free\fP, \fBpcre_stack_malloc\fP, and \fBpcre_stack_free\fP, and the +callout function pointed to by \fBpcre_callout\fP, are shared by all threads. +.P +The compiled form of a regular expression is not altered during matching, so +the same compiled pattern can safely be used by several threads at once. +. +. +.SH "SAVING PRECOMPILED PATTERNS FOR LATER USE" +.rs +.sp +The compiled form of a regular expression can be saved and re-used at a later +time, possibly by a different program, and even on a host other than the one on +which it was compiled. Details are given in the +.\" HREF +\fBpcreprecompile\fP +.\" +documentation. +. +. +.SH "CHECKING BUILD-TIME OPTIONS" +.rs +.sp +.B int pcre_config(int \fIwhat\fP, void *\fIwhere\fP); +.PP +The function \fBpcre_config()\fP makes it possible for a PCRE client to +discover which optional features have been compiled into the PCRE library. The +.\" HREF +\fBpcrebuild\fP +.\" +documentation has more details about these optional features. +.P +The first argument for \fBpcre_config()\fP is an integer, specifying which +information is required; the second argument is a pointer to a variable into +which the information is placed. The following information is available: +.sp + PCRE_CONFIG_UTF8 +.sp +The output is an integer that is set to one if UTF-8 support is available; +otherwise it is set to zero. +.sp + PCRE_CONFIG_UNICODE_PROPERTIES +.sp +The output is an integer that is set to one if support for Unicode character +properties is available; otherwise it is set to zero. +.sp + PCRE_CONFIG_NEWLINE +.sp +The output is an integer whose value specifies the default character sequence +that is recognized as meaning "newline". The three values that are supported +are: 10 for LF, 13 for CR, and 3338 for CRLF. The default should normally be +the standard sequence for your operating system. +.sp + PCRE_CONFIG_LINK_SIZE +.sp +The output is an integer that contains the number of bytes used for internal +linkage in compiled regular expressions. The value is 2, 3, or 4. Larger values +allow larger regular expressions to be compiled, at the expense of slower +matching. The default value of 2 is sufficient for all but the most massive +patterns, since it allows the compiled pattern to be up to 64K in size. +.sp + PCRE_CONFIG_POSIX_MALLOC_THRESHOLD +.sp +The output is an integer that contains the threshold above which the POSIX +interface uses \fBmalloc()\fP for output vectors. Further details are given in +the +.\" HREF +\fBpcreposix\fP +.\" +documentation. +.sp + PCRE_CONFIG_MATCH_LIMIT +.sp +The output is an integer that gives the default limit for the number of +internal matching function calls in a \fBpcre_exec()\fP execution. Further +details are given with \fBpcre_exec()\fP below. +.sp + PCRE_CONFIG_MATCH_LIMIT_RECURSION +.sp +The output is an integer that gives the default limit for the depth of +recursion when calling the internal matching function in a \fBpcre_exec()\fP +execution. Further details are given with \fBpcre_exec()\fP below. +.sp + PCRE_CONFIG_STACKRECURSE +.sp +The output is an integer that is set to one if internal recursion when running +\fBpcre_exec()\fP is implemented by recursive function calls that use the stack +to remember their state. This is the usual way that PCRE is compiled. The +output is zero if PCRE was compiled to use blocks of data on the heap instead +of recursive function calls. In this case, \fBpcre_stack_malloc\fP and +\fBpcre_stack_free\fP are called to manage memory blocks on the heap, thus +avoiding the use of the stack. +. +. +.SH "COMPILING A PATTERN" +.rs +.sp +.B pcre *pcre_compile(const char *\fIpattern\fP, int \fIoptions\fP, +.ti +5n +.B const char **\fIerrptr\fP, int *\fIerroffset\fP, +.ti +5n +.B const unsigned char *\fItableptr\fP); +.sp +.B pcre *pcre_compile2(const char *\fIpattern\fP, int \fIoptions\fP, +.ti +5n +.B int *\fIerrorcodeptr\fP, +.ti +5n +.B const char **\fIerrptr\fP, int *\fIerroffset\fP, +.ti +5n +.B const unsigned char *\fItableptr\fP); +.P +Either of the functions \fBpcre_compile()\fP or \fBpcre_compile2()\fP can be +called to compile a pattern into an internal form. The only difference between +the two interfaces is that \fBpcre_compile2()\fP has an additional argument, +\fIerrorcodeptr\fP, via which a numerical error code can be returned. +.P +The pattern is a C string terminated by a binary zero, and is passed in the +\fIpattern\fP argument. A pointer to a single block of memory that is obtained +via \fBpcre_malloc\fP is returned. This contains the compiled code and related +data. The \fBpcre\fP type is defined for the returned block; this is a typedef +for a structure whose contents are not externally defined. It is up to the +caller to free the memory (via \fBpcre_free\fP) when it is no longer required. +.P +Although the compiled code of a PCRE regex is relocatable, that is, it does not +depend on memory location, the complete \fBpcre\fP data block is not +fully relocatable, because it may contain a copy of the \fItableptr\fP +argument, which is an address (see below). +.P +The \fIoptions\fP argument contains independent bits that affect the +compilation. It should be zero if no options are required. The available +options are described below. Some of them, in particular, those that are +compatible with Perl, can also be set and unset from within the pattern (see +the detailed description in the +.\" HREF +\fBpcrepattern\fP +.\" +documentation). For these options, the contents of the \fIoptions\fP argument +specifies their initial settings at the start of compilation and execution. The +PCRE_ANCHORED and PCRE_NEWLINE_\fIxxx\fP options can be set at the time of +matching as well as at compile time. +.P +If \fIerrptr\fP is NULL, \fBpcre_compile()\fP returns NULL immediately. +Otherwise, if compilation of a pattern fails, \fBpcre_compile()\fP returns +NULL, and sets the variable pointed to by \fIerrptr\fP to point to a textual +error message. This is a static string that is part of the library. You must +not try to free it. The offset from the start of the pattern to the character +where the error was discovered is placed in the variable pointed to by +\fIerroffset\fP, which must not be NULL. If it is, an immediate error is given. +.P +If \fBpcre_compile2()\fP is used instead of \fBpcre_compile()\fP, and the +\fIerrorcodeptr\fP argument is not NULL, a non-zero error code number is +returned via this argument in the event of an error. This is in addition to the +textual error message. Error codes and messages are listed below. +.P +If the final argument, \fItableptr\fP, is NULL, PCRE uses a default set of +character tables that are built when PCRE is compiled, using the default C +locale. Otherwise, \fItableptr\fP must be an address that is the result of a +call to \fBpcre_maketables()\fP. This value is stored with the compiled +pattern, and used again by \fBpcre_exec()\fP, unless another table pointer is +passed to it. For more discussion, see the section on locale support below. +.P +This code fragment shows a typical straightforward call to \fBpcre_compile()\fP: +.sp + pcre *re; + const char *error; + int erroffset; + re = pcre_compile( + "^A.*Z", /* the pattern */ + 0, /* default options */ + &error, /* for error message */ + &erroffset, /* for error offset */ + NULL); /* use default character tables */ +.sp +The following names for option bits are defined in the \fBpcre.h\fP header +file: +.sp + PCRE_ANCHORED +.sp +If this bit is set, the pattern is forced to be "anchored", that is, it is +constrained to match only at the first matching point in the string that is +being searched (the "subject string"). This effect can also be achieved by +appropriate constructs in the pattern itself, which is the only way to do it in +Perl. +.sp + PCRE_AUTO_CALLOUT +.sp +If this bit is set, \fBpcre_compile()\fP automatically inserts callout items, +all with number 255, before each pattern item. For discussion of the callout +facility, see the +.\" HREF +\fBpcrecallout\fP +.\" +documentation. +.sp + PCRE_CASELESS +.sp +If this bit is set, letters in the pattern match both upper and lower case +letters. It is equivalent to Perl's /i option, and it can be changed within a +pattern by a (?i) option setting. In UTF-8 mode, PCRE always understands the +concept of case for characters whose values are less than 128, so caseless +matching is always possible. For characters with higher values, the concept of +case is supported if PCRE is compiled with Unicode property support, but not +otherwise. If you want to use caseless matching for characters 128 and above, +you must ensure that PCRE is compiled with Unicode property support as well as +with UTF-8 support. +.sp + PCRE_DOLLAR_ENDONLY +.sp +If this bit is set, a dollar metacharacter in the pattern matches only at the +end of the subject string. Without this option, a dollar also matches +immediately before a newline at the end of the string (but not before any other +newlines). The PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is set. +There is no equivalent to this option in Perl, and no way to set it within a +pattern. +.sp + PCRE_DOTALL +.sp +If this bit is set, a dot metacharater in the pattern matches all characters, +including those that indicate newline. Without it, a dot does not match when +the current position is at a newline. This option is equivalent to Perl's /s +option, and it can be changed within a pattern by a (?s) option setting. A +negative class such as [^a] always matches newlines, independent of the setting +of this option. +.sp + PCRE_DUPNAMES +.sp +If this bit is set, names used to identify capturing subpatterns need not be +unique. This can be helpful for certain types of pattern when it is known that +only one instance of the named subpattern can ever be matched. There are more +details of named subpatterns below; see also the +.\" HREF +\fBpcrepattern\fP +.\" +documentation. +.sp + PCRE_EXTENDED +.sp +If this bit is set, whitespace data characters in the pattern are totally +ignored except when escaped or inside a character class. Whitespace does not +include the VT character (code 11). In addition, characters between an +unescaped # outside a character class and the next newline, inclusive, are also +ignored. This is equivalent to Perl's /x option, and it can be changed within a +pattern by a (?x) option setting. +.P +This option makes it possible to include comments inside complicated patterns. +Note, however, that this applies only to data characters. Whitespace characters +may never appear within special character sequences in a pattern, for example +within the sequence (?( which introduces a conditional subpattern. +.sp + PCRE_EXTRA +.sp +This option was invented in order to turn on additional functionality of PCRE +that is incompatible with Perl, but it is currently of very little use. When +set, any backslash in a pattern that is followed by a letter that has no +special meaning causes an error, thus reserving these combinations for future +expansion. By default, as in Perl, a backslash followed by a letter with no +special meaning is treated as a literal. (Perl can, however, be persuaded to +give a warning for this.) There are at present no other features controlled by +this option. It can also be set by a (?X) option setting within a pattern. +.sp + PCRE_FIRSTLINE +.sp +If this option is set, an unanchored pattern is required to match before or at +the first newline in the subject string, though the matched text may continue +over the newline. +.sp + PCRE_MULTILINE +.sp +By default, PCRE treats the subject string as consisting of a single line of +characters (even if it actually contains newlines). The "start of line" +metacharacter (^) matches only at the start of the string, while the "end of +line" metacharacter ($) matches only at the end of the string, or before a +terminating newline (unless PCRE_DOLLAR_ENDONLY is set). This is the same as +Perl. +.P +When PCRE_MULTILINE it is set, the "start of line" and "end of line" constructs +match immediately following or immediately before internal newlines in the +subject string, respectively, as well as at the very start and end. This is +equivalent to Perl's /m option, and it can be changed within a pattern by a +(?m) option setting. If there are no newlines in a subject string, or no +occurrences of ^ or $ in a pattern, setting PCRE_MULTILINE has no effect. +.sp + PCRE_NEWLINE_CR + PCRE_NEWLINE_LF + PCRE_NEWLINE_CRLF +.sp +These options override the default newline definition that was chosen when PCRE +was built. Setting the first or the second specifies that a newline is +indicated by a single character (CR or LF, respectively). Setting both of them +specifies that a newline is indicated by the two-character CRLF sequence. For +convenience, PCRE_NEWLINE_CRLF is defined to contain both bits. The only time +that a line break is relevant when compiling a pattern is if PCRE_EXTENDED is +set, and an unescaped # outside a character class is encountered. This +indicates a comment that lasts until after the next newline. +.P +The newline option set at compile time becomes the default that is used for +\fBpcre_exec()\fP and \fBpcre_dfa_exec()\fP, but it can be overridden. +.sp + PCRE_NO_AUTO_CAPTURE +.sp +If this option is set, it disables the use of numbered capturing parentheses in +the pattern. Any opening parenthesis that is not followed by ? behaves as if it +were followed by ?: but named parentheses can still be used for capturing (and +they acquire numbers in the usual way). There is no equivalent of this option +in Perl. +.sp + PCRE_UNGREEDY +.sp +This option inverts the "greediness" of the quantifiers so that they are not +greedy by default, but become greedy if followed by "?". It is not compatible +with Perl. It can also be set by a (?U) option setting within the pattern. +.sp + PCRE_UTF8 +.sp +This option causes PCRE to regard both the pattern and the subject as strings +of UTF-8 characters instead of single-byte character strings. However, it is +available only when PCRE is built to include UTF-8 support. If not, the use +of this option provokes an error. Details of how this option changes the +behaviour of PCRE are given in the +.\" HTML <a href="pcre.html#utf8support"> +.\" </a> +section on UTF-8 support +.\" +in the main +.\" HREF +\fBpcre\fP +.\" +page. +.sp + PCRE_NO_UTF8_CHECK +.sp +When PCRE_UTF8 is set, the validity of the pattern as a UTF-8 string is +automatically checked. If an invalid UTF-8 sequence of bytes is found, +\fBpcre_compile()\fP returns an error. If you already know that your pattern is +valid, and you want to skip this check for performance reasons, you can set the +PCRE_NO_UTF8_CHECK option. When it is set, the effect of passing an invalid +UTF-8 string as a pattern is undefined. It may cause your program to crash. +Note that this option can also be passed to \fBpcre_exec()\fP and +\fBpcre_dfa_exec()\fP, to suppress the UTF-8 validity checking of subject +strings. +. +. +.SH "COMPILATION ERROR CODES" +.rs +.sp +The following table lists the error codes than may be returned by +\fBpcre_compile2()\fP, along with the error messages that may be returned by +both compiling functions. +.sp + 0 no error + 1 \e at end of pattern + 2 \ec at end of pattern + 3 unrecognized character follows \e + 4 numbers out of order in {} quantifier + 5 number too big in {} quantifier + 6 missing terminating ] for character class + 7 invalid escape sequence in character class + 8 range out of order in character class + 9 nothing to repeat + 10 operand of unlimited repeat could match the empty string + 11 internal error: unexpected repeat + 12 unrecognized character after (? + 13 POSIX named classes are supported only within a class + 14 missing ) + 15 reference to non-existent subpattern + 16 erroffset passed as NULL + 17 unknown option bit(s) set + 18 missing ) after comment + 19 parentheses nested too deeply + 20 regular expression too large + 21 failed to get memory + 22 unmatched parentheses + 23 internal error: code overflow + 24 unrecognized character after (?< + 25 lookbehind assertion is not fixed length + 26 malformed number or name after (?( + 27 conditional group contains more than two branches + 28 assertion expected after (?( + 29 (?R or (?digits must be followed by ) + 30 unknown POSIX class name + 31 POSIX collating elements are not supported + 32 this version of PCRE is not compiled with PCRE_UTF8 support + 33 spare error + 34 character value in \ex{...} sequence is too large + 35 invalid condition (?(0) + 36 \eC not allowed in lookbehind assertion + 37 PCRE does not support \eL, \el, \eN, \eU, or \eu + 38 number after (?C is > 255 + 39 closing ) for (?C expected + 40 recursive call could loop indefinitely + 41 unrecognized character after (?P + 42 syntax error after (?P + 43 two named subpatterns have the same name + 44 invalid UTF-8 string + 45 support for \eP, \ep, and \eX has not been compiled + 46 malformed \eP or \ep sequence + 47 unknown property name after \eP or \ep + 48 subpattern name is too long (maximum 32 characters) + 49 too many named subpatterns (maximum 10,000) + 50 repeated subpattern is too long + 51 octal value is greater than \e377 (not in UTF-8 mode) +. +. +.SH "STUDYING A PATTERN" +.rs +.sp +.B pcre_extra *pcre_study(const pcre *\fIcode\fP, int \fIoptions\fP +.ti +5n +.B const char **\fIerrptr\fP); +.PP +If a compiled pattern is going to be used several times, it is worth spending +more time analyzing it in order to speed up the time taken for matching.

However, a \fBpcre_extra\fP block also contains other +fields that can be set by the caller before the block is passed; these are +described +.\" HTML <a href="#extradata"> +.\" </a> +below +.\" +in the section on matching a pattern. +.P +If studying the pattern does not produce any additional information +\fBpcre_study()\fP returns NULL. In that circumstance, if the calling program +wants to pass any of the other fields to \fBpcre_exec()\fP, it must set up its +own \fBpcre_extra\fP block. +.P +The second argument of \fBpcre_study()\fP contains option bits. At present, no +options are defined, and this argument should always be zero. +.P +The third argument for \fBpcre_study()\fP is a pointer for an error message. If +studying succeeds (even if no data is returned), the variable it points to is +set to NULL. Otherwise it is set to point to a textual error message. This is a +static string that is part of the library. You must not try to free it. You +should test the error pointer for NULL after calling \fBpcre_study()\fP, to be +sure that it has run successfully. +.P +This is a typical call to \fBpcre_study\fP(): +.sp + pcre_extra *pe; + pe = pcre_study( + re, /* result of pcre_compile() */ + 0, /* no options exist */ + &error); /* set to NULL or points to a message */ +.sp +At present, studying a pattern is useful only for non-anchored patterns that do +not have a single fixed starting character. A bitmap of possible starting +bytes is created. +. +. +.\" HTML <a name="localesupport"></a> +.SH "LOCALE SUPPORT" +.rs +.sp +PCRE handles caseless matching, and determines whether characters are letters +digits, or whatever, by reference to a set of tables, indexed by character +value. When running in UTF-8 mode, this applies only to characters with codes +less than 128. Higher-valued codes never match escapes such as \ew or \ed, but +can be tested with \ep if PCRE is built with Unicode character property +support. The use of locales with Unicode is discouraged. +.P +An internal set of tables is created in the default C locale when PCRE is +built. This is used when the final argument of \fBpcre_compile()\fP is NULL, +and is sufficient for many applications. An alternative set of tables can, +however, be supplied. These may be created in a different locale from the +default. As more and more applications change to using Unicode, the need for +this locale support is expected to die away. +.P +External tables are built by calling the \fBpcre_maketables()\fP function, +which has no arguments, in the relevant locale. The result can then be passed +to \fBpcre_compile()\fP or \fBpcre_exec()\fP as often as necessary. For +example, to build and use tables that are appropriate for the French locale +(where accented characters with values greater than 128 are treated as letters), +the following code could be used: +.sp + setlocale(LC_CTYPE, "fr_FR"); + tables = pcre_maketables(); + re = pcre_compile(..., tables); +.sp +When \fBpcre_maketables()\fP runs, the tables are built in memory that is +obtained via \fBpcre_malloc\fP. It is the caller's responsibility to ensure +that the memory containing the tables remains available for as long as it is +needed. +.P +The pointer that is passed to \fBpcre_compile()\fP is saved with the compiled +pattern, and the same tables are used via this pointer by \fBpcre_study()\fP +and normally also by \fBpcre_exec()\fP. Thus, by default, for any single +pattern, compilation, studying and matching all happen in the same locale, but +different patterns can be compiled in different locales. +.P +It is possible to pass a table pointer or NULL (indicating the use of the +internal tables) to \fBpcre_exec()\fP.

The fourth +argument should point to an \fBint\fP variable. If there is no such byte, -1 is +returned. For anchored patterns, a last literal byte is recorded only if it +follows something of variable length. For example, for the pattern +/^a\ed+z\ed+/ the returned value is "z", but for /^a\edz\ed/ the returned value +is -1. +.sp + PCRE_INFO_NAMECOUNT + PCRE_INFO_NAMEENTRYSIZE + PCRE_INFO_NAMETABLE +.sp +PCRE supports the use of named as well as numbered capturing parentheses. The +names are just an additional way of identifying the parentheses, which still +acquire numbers. Several convenience functions such as +\fBpcre_get_named_substring()\fP are provided for extracting captured +substrings by name. It is also possible to extract the data directly, by first +converting the name to a number in order to access the correct pointers in the +output vector (described with \fBpcre_exec()\fP below). To do the conversion, +you need to use the name-to-number map, which is described by these three +values. +.P +The map consists of a number of fixed-size entries. PCRE_INFO_NAMECOUNT gives +the number of entries, and PCRE_INFO_NAMEENTRYSIZE gives the size of each +entry; both of these return an \fBint\fP value. The entry size depends on the +length of the longest name. PCRE_INFO_NAMETABLE returns a pointer to the first +entry of the table (a pointer to \fBchar\fP). The first two bytes of each entry +are the number of the capturing parenthesis, most significant byte first. The +rest of the entry is the corresponding name, zero terminated. The names are in +alphabetical order. When PCRE_DUPNAMES is set, duplicate names are in order of +their parentheses numbers.

The +classic example is the use of nested unlimited repeats. +.P +Internally, PCRE uses a function called \fBmatch()\fP which it calls repeatedly +(sometimes recursively). The limit set by \fImatch_limit\fP is imposed on the +number of times this function is called during a match, which has the effect of +limiting the amount of backtracking that can take place. For patterns that are +not anchored, the count restarts from zero for each position in the subject +string. +.P +The default value for the limit can be set when PCRE is built; the default +default is 10 million, which handles all but the most extreme cases. You can +override the default by suppling \fBpcre_exec()\fP with a \fBpcre_extra\fP +block in which \fImatch_limit\fP is set, and PCRE_EXTRA_MATCH_LIMIT is set in +the \fIflags\fP field. If the limit is exceeded, \fBpcre_exec()\fP returns +PCRE_ERROR_MATCHLIMIT. +.P +The \fImatch_limit_recursion\fP field is similar to \fImatch_limit\fP, but +instead of limiting the total number of times that \fBmatch()\fP is called, it +limits the depth of recursion. The recursion depth is a smaller number than the +total number of calls, because not all calls to \fBmatch()\fP are recursive. +This limit is of use only if it is set smaller than \fImatch_limit\fP. +.P +Limiting the recursion depth limits the amount of stack that can be used, or, +when PCRE has been compiled to use memory on the heap instead of the stack, the +amount of heap memory that can be used. +.P +The default value for \fImatch_limit_recursion\fP can be set when PCRE is +built; the default default is the same value as the default for +\fImatch_limit\fP. You can override the default by suppling \fBpcre_exec()\fP +with a \fBpcre_extra\fP block in which \fImatch_limit_recursion\fP is set, and +PCRE_EXTRA_MATCH_LIMIT_RECURSION is set in the \fIflags\fP field. If the limit +is exceeded, \fBpcre_exec()\fP returns PCRE_ERROR_RECURSIONLIMIT. +.P +The \fIpcre_callout\fP field is used in conjunction with the "callout" feature, +which is described in the +.\" HREF +\fBpcrecallout\fP +.\" +documentation. +.P +The \fItables\fP field is used to pass a character tables pointer to +\fBpcre_exec()\fP; this overrides the value that is stored with the compiled +pattern. A non-NULL value is stored with the compiled pattern only if custom +tables were supplied to \fBpcre_compile()\fP via its \fItableptr\fP argument. +If NULL is passed to \fBpcre_exec()\fP using this mechanism, it forces PCRE's +internal tables to be used. This facility is helpful when re-using patterns +that have been saved after compiling with an external set of tables, because +the external tables might be at a different address when \fBpcre_exec()\fP is +called.

If a pattern was compiled with PCRE_ANCHORED, or turned out +to be anchored by virtue of its contents, it cannot be made unachored at +matching time. +.sp + PCRE_NEWLINE_CR + PCRE_NEWLINE_LF + PCRE_NEWLINE_CRLF +.sp +These options override the newline definition that was chosen or defaulted when +the pattern was compiled. For details, see the description \fBpcre_compile()\fP +above. During matching, the newline choice affects the behaviour of the dot, +circumflex, and dollar metacharacters. +.sp + PCRE_NOTBOL +.sp +This option specifies that first character of the subject string is not the +beginning of a line, so the circumflex metacharacter should not match before +it. Setting this without PCRE_MULTILINE (at compile time) causes circumflex +never to match. This option affects only the behaviour of the circumflex +metacharacter. It does not affect \eA. +.sp + PCRE_NOTEOL +.sp +This option specifies that the end of the subject string is not the end of a +line, so the dollar metacharacter should not match it nor (except in multiline +mode) a newline immediately before it. Setting this without PCRE_MULTILINE (at +compile time) causes dollar never to match. This option affects only the +behaviour of the dollar metacharacter. It does not affect \eZ or \ez. +.sp + PCRE_NOTEMPTY +.sp +An empty string is not considered to be a valid match if this option is set. If +there are alternatives in the pattern, they are tried. If all the alternatives +match the empty string, the entire match fails. For example, if the pattern +.sp + a?b? +.sp +is applied to a string not beginning with "a" or "b", it matches the empty +string at the start of the subject. With PCRE_NOTEMPTY set, this match is not +valid, so PCRE searches further into the string for occurrences of "a" or "b". +.P +Perl has no direct equivalent of PCRE_NOTEMPTY, but it does make a special case +of a pattern match of the empty string within its \fBsplit()\fP function, and +when using the /g modifier. It is possible to emulate Perl's behaviour after +matching a null string by first trying the match again at the same offset with +PCRE_NOTEMPTY and PCRE_ANCHORED, and then if that fails by advancing the +starting offset (see below) and trying an ordinary match again. There is some +code that demonstrates how to do this in the \fIpcredemo.c\fP sample program. +.sp + PCRE_NO_UTF8_CHECK +.sp +When PCRE_UTF8 is set at compile time, the validity of the subject as a UTF-8 +string is automatically checked when \fBpcre_exec()\fP is subsequently called. +The value of \fIstartoffset\fP is also checked to ensure that it points to the +start of a UTF-8 character. If an invalid UTF-8 sequence of bytes is found, +\fBpcre_exec()\fP returns the error PCRE_ERROR_BADUTF8. If \fIstartoffset\fP +contains an invalid value, PCRE_ERROR_BADUTF8_OFFSET is returned. +.P +If you already know that your subject is valid, and you want to skip these +checks for performance reasons, you can set the PCRE_NO_UTF8_CHECK option when +calling \fBpcre_exec()\fP. You might want to do this for the second and +subsequent calls to \fBpcre_exec()\fP if you are making repeated calls to find +all the matches in a single subject string. However, you should be sure that +the value of \fIstartoffset\fP points to the start of a UTF-8 character. When +PCRE_NO_UTF8_CHECK is set, the effect of passing an invalid UTF-8 string as a +subject, or a value of \fIstartoffset\fP that does not point to the start of a +UTF-8 character, is undefined. Your program may crash. +.sp + PCRE_PARTIAL +.sp +This option turns on the partial matching feature. If the subject string fails +to match the pattern, but at some point during the matching process the end of +the subject was reached (that is, the subject partially matches the pattern and +the failure to match occurred only because there were not enough subject +characters), \fBpcre_exec()\fP returns PCRE_ERROR_PARTIAL instead of +PCRE_ERROR_NOMATCH. When PCRE_PARTIAL is used, there are restrictions on what +may appear in the pattern. These are discussed in the +.\" HREF +\fBpcrepartial\fP +.\" +documentation. +. +.SS "The string to be matched by \fBpcre_exec()\fP" +.rs +.sp +The subject string is passed to \fBpcre_exec()\fP as a pointer in +\fIsubject\fP, a length in \fIlength\fP, and a starting byte offset in +\fIstartoffset\fP. In UTF-8 mode, the byte offset must point to the start of a +UTF-8 character. Unlike the pattern string, the subject may contain binary zero +bytes. When the starting offset is zero, the search for a match starts at the +beginning of the subject, and this is by far the most common case. +.P +A non-zero starting offset is useful when searching for another match in the +same subject by calling \fBpcre_exec()\fP again after a previous success. +Setting \fIstartoffset\fP differs from just passing over a shortened string and +setting PCRE_NOTBOL in the case of a pattern that begins with any kind of +lookbehind. For example, consider the pattern +.sp + \eBiss\eB +.sp +which finds occurrences of "iss" in the middle of words. (\eB matches only if +the current position in the subject is not a word boundary.) When applied to +the string "Mississipi" the first call to \fBpcre_exec()\fP finds the first +occurrence. If \fBpcre_exec()\fP is called again with just the remainder of the +subject, namely "issipi", it does not match, because \eB is always false at the +start of the subject, which is deemed to be a word boundary. However, if +\fBpcre_exec()\fP is passed the entire string again, but with \fIstartoffset\fP +set to 4, it finds the second occurrence of "iss" because it is able to look +behind the starting point to discover that it is preceded by a letter. +.P +If a non-zero starting offset is passed when the pattern is anchored, one +attempt to match at the given offset is made. This can only succeed if the +pattern does not require the match to be at the start of the subject. +. +.SS "How \fBpcre_exec()\fP returns captured substrings" +.rs +.sp +In general, a pattern matches a certain portion of the subject, and in +addition, further substrings from the subject may be picked out by parts of the +pattern. Following the usage in Jeffrey Friedl's book, this is called +"capturing" in what follows, and the phrase "capturing subpattern" is used for +a fragment of a pattern that picks out a substring. PCRE supports several other +kinds of parenthesized subpattern that do not cause substrings to be captured. +.P +Captured substrings are returned to the caller via a vector of integer offsets +whose address is passed in \fIovector\fP. The number of elements in the vector +is passed in \fIovecsize\fP, which must be a non-negative number. \fBNote\fP: +this argument is NOT the size of \fIovector\fP in bytes. +.P +The first two-thirds of the vector is used to pass back captured substrings, +each substring using a pair of integers. The remaining third of the vector is +used as workspace by \fBpcre_exec()\fP while matching capturing subpatterns, +and is not available for passing back information. The length passed in +\fIovecsize\fP should always be a multiple of three. If it is not, it is +rounded down. +.P +When a match is successful, information about captured substrings is returned +in pairs of integers, starting at the beginning of \fIovector\fP, and +continuing up to two-thirds of its length at the most. The first element of a +pair is set to the offset of the first character in a substring, and the second +is set to the offset of the first character after the end of a substring. The +first pair, \fIovector[0]\fP and \fIovector[1]\fP, identify the portion of the +subject string matched by the entire pattern. The next pair is used for the +first capturing subpattern, and so on. The value returned by \fBpcre_exec()\fP +is one more than the highest numbered pair that has been set. For example, if +two substrings have been captured, the returned value is 3. If there are no +capturing subpatterns, the return value from a successful match is 1, +indicating that just the first pair of offsets has been set. +.P +If a capturing subpattern is matched repeatedly, it is the last portion of the +string that it matched that is returned. +.P +If the vector is too small to hold all the captured substring offsets, it is +used as far as possible (up to two-thirds of its length), and the function +returns a value of zero. In particular, if the substring offsets are not of +interest, \fBpcre_exec()\fP may be called with \fIovector\fP passed as NULL and +\fIovecsize\fP as zero. However, if the pattern contains back references and +the \fIovector\fP is not big enough to remember the related substrings, PCRE +has to get additional memory for use during matching. Thus it is usually +advisable to supply an \fIovector\fP. +.P +The \fBpcre_info()\fP function can be used to find out how many capturing +subpatterns there are in a compiled pattern. The smallest size for +\fIovector\fP that will allow for \fIn\fP captured substrings, in addition to +the offsets of the substring matched by the whole pattern, is (\fIn\fP+1)*3. +.P +It is possible for capturing subpattern number \fIn+1\fP to match some part of +the subject when subpattern \fIn\fP has not been used at all. For example, if +the string "abc" is matched against the pattern (a|(z))(bc) the return from the +function is 4, and subpatterns 1 and 3 are matched, but 2 is not. When this +happens, both values in the offset pairs corresponding to unused subpatterns +are set to -1. +.P +Offset values that correspond to unused subpatterns at the end of the +expression are also set to -1. For example, if the string "abc" is matched +against the pattern (abc)(x(yz)?)? subpatterns 2 and 3 are not matched. The +return from the function is 2, because the highest used capturing subpattern +number is 1. However, you can refer to the offsets for the second and third +capturing subpatterns if you wish (assuming the vector is large enough, of +course). +.P +Some convenience functions are provided for extracting the captured substrings +as separate strings. These are described below. +. +.\" HTML <a name="errorlist"></a> +.SS "Error return values from \fBpcre_exec()\fP" +.rs +.sp +If \fBpcre_exec()\fP fails, it returns a negative number.

This is the error that PCRE gives when the magic number is +not present. +.sp + PCRE_ERROR_UNKNOWN_NODE (-5) +.sp +While running the pattern match, an unknown item was encountered in the +compiled pattern. This error could be caused by a bug in PCRE or by overwriting +of the compiled pattern. +.sp + PCRE_ERROR_NOMEMORY (-6) +.sp +If a pattern contains back references, but the \fIovector\fP that is passed to +\fBpcre_exec()\fP is not big enough to remember the referenced substrings, PCRE +gets a block of memory at the start of matching to use for this purpose.

The memory is +automatically freed at the end of matching. +.sp + PCRE_ERROR_NOSUBSTRING (-7) +.sp +This error is used by the \fBpcre_copy_substring()\fP, +\fBpcre_get_substring()\fP, and \fBpcre_get_substring_list()\fP functions (see +below).

For convenience, the functions +\fBpcre_copy_substring()\fP, \fBpcre_get_substring()\fP, and +\fBpcre_get_substring_list()\fP are provided for extracting captured substrings +as new, separate, zero-terminated strings. These functions identify substrings +by number. The next section describes functions for extracting named +substrings. +.P +A substring that contains a binary zero is correctly extracted and has a +further zero added on the end, but the result is not, of course, a C string. +However, you can process such a string by referring to the length that is +returned by \fBpcre_copy_substring()\fP and \fBpcre_get_substring()\fP. +Unfortunately, the interface to \fBpcre_get_substring_list()\fP is not adequate +for handling strings containing binary zeros, because the end of the final +string is not independently indicated. +.P +The first three arguments are the same for all three of these functions: +\fIsubject\fP is the subject string that has just been successfully matched, +\fIovector\fP is a pointer to the vector of integer offsets that was passed to +\fBpcre_exec()\fP, and \fIstringcount\fP is the number of substrings that were +captured by the match, including the substring that matched the entire regular +expression. This is the value returned by \fBpcre_exec()\fP if it is greater +than zero. If \fBpcre_exec()\fP returned zero, indicating that it ran out of +space in \fIovector\fP, the value passed as \fIstringcount\fP should be the +number of elements in the vector divided by three. +.P +The functions \fBpcre_copy_substring()\fP and \fBpcre_get_substring()\fP +extract a single substring, whose number is given as \fIstringnumber\fP. A +value of zero extracts the substring that matched the entire pattern, whereas +higher values extract the captured substrings. For \fBpcre_copy_substring()\fP, +the string is placed in \fIbuffer\fP, whose length is given by +\fIbuffersize\fP, while for \fBpcre_get_substring()\fP a new block of memory is +obtained via \fBpcre_malloc\fP, and its address is returned via +\fIstringptr\fP. The yield of the function is the length of the string, not +including the terminating zero, or one of +.sp + PCRE_ERROR_NOMEMORY (-6) +.sp +The buffer was too small for \fBpcre_copy_substring()\fP, or the attempt to get +memory failed for \fBpcre_get_substring()\fP. +.sp + PCRE_ERROR_NOSUBSTRING (-7) +.sp +There is no substring whose number is \fIstringnumber\fP. +.P +The \fBpcre_get_substring_list()\fP function extracts all available substrings +and builds a list of pointers to them. All this is done in a single block of +memory that is obtained via \fBpcre_malloc\fP. The address of the memory block +is returned via \fIlistptr\fP, which is also the start of the list of string +pointers. The end of the list is marked by a NULL pointer. The yield of the +function is zero if all went well, or +.sp + PCRE_ERROR_NOMEMORY (-6) +.sp +if the attempt to get the memory block failed. +.P +When any of these functions encounter a substring that is unset, which can +happen when capturing subpattern number \fIn+1\fP matches some part of the +subject, but subpattern \fIn\fP has not been used at all, they return an empty +string. This can be distinguished from a genuine zero-length substring by +inspecting the appropriate offset in \fIovector\fP, which is negative for unset +substrings. +.P +The two convenience functions \fBpcre_free_substring()\fP and +\fBpcre_free_substring_list()\fP can be used to free the memory returned by +a previous call of \fBpcre_get_substring()\fP or +\fBpcre_get_substring_list()\fP, respectively. They do nothing more than call +the function pointed to by \fBpcre_free\fP, which of course could be called +directly from a C program. However, PCRE is used in some situations where it is +linked via a special interface to another programming language that cannot use +\fBpcre_free\fP directly; it is for these cases that the functions are +provided. +. +. +.SH "EXTRACTING CAPTURED SUBSTRINGS BY NAME" +.rs +.sp +.B int pcre_get_stringnumber(const pcre *\fIcode\fP, +.ti +5n +.B const char *\fIname\fP); +.PP +.br +.B int pcre_copy_named_substring(const pcre *\fIcode\fP, +.ti +5n +.B const char *\fIsubject\fP, int *\fIovector\fP, +.ti +5n +.B int \fIstringcount\fP, const char *\fIstringname\fP, +.ti +5n +.B char *\fIbuffer\fP, int \fIbuffersize\fP); +.PP +.br +.B int pcre_get_named_substring(const pcre *\fIcode\fP, +.ti +5n +.B const char *\fIsubject\fP, int *\fIovector\fP, +.ti +5n +.B int \fIstringcount\fP, const char *\fIstringname\fP, +.ti +5n +.B const char **\fIstringptr\fP); +.PP +To extract a substring by name, you first have to find associated number. +For example, for this pattern +.sp + (a+)b(?P<xxx>\ed+)... +.sp +the number of the subpattern called "xxx" is 2. If the name is known to be +unique (PCRE_DUPNAMES was not set), you can find the number from the name by +calling \fBpcre_get_stringnumber()\fP. The first argument is the compiled +pattern, and the second is the name. The yield of the function is the +subpattern number, or PCRE_ERROR_NOSUBSTRING (-7) if there is no subpattern of +that name. +.P +Given the number, you can extract the substring directly, or use one of the +functions described in the previous section. For convenience, there are also +two functions that do the whole job. +.P +Most of the arguments of \fBpcre_copy_named_substring()\fP and +\fBpcre_get_named_substring()\fP are the same as those for the similarly named +functions that extract by number. As these are described in the previous +section, they are not re-described here. There are just two differences: +.P +First, instead of a substring number, a substring name is given. Second, there +is an extra argument, given at the start, which is a pointer to the compiled +pattern. This is needed in order to gain access to the name-to-number +translation table. +.P +These functions call \fBpcre_get_stringnumber()\fP, and if it succeeds, they +then call \fIpcre_copy_substring()\fP or \fIpcre_get_substring()\fP, as +appropriate. +. +. +.SH "DUPLICATE SUBPATTERN NAMES" +.rs +.sp +.B int pcre_get_stringtable_entries(const pcre *\fIcode\fP, +.ti +5n +.B const char *\fIname\fP, char **\fIfirst\fP, char **\fIlast\fP); +.PP +When a pattern is compiled with the PCRE_DUPNAMES option, names for subpatterns +are not required to be unique. Normally, patterns with duplicate names are such +that in any one match, only one of the named subpatterns participates. An +example is shown in the +.\" HREF +\fBpcrepattern\fP +.\" +documentation. When duplicates are present, \fBpcre_copy_named_substring()\fP +and \fBpcre_get_named_substring()\fP return the first substring corresponding +to the given name that is set. If none are set, an empty string is returned. +The \fBpcre_get_stringnumber()\fP function returns one of the numbers that are +associated with the name, but it is not defined which it is. +.sp +If you want to get full details of all captured substrings for a given name, +you must use the \fBpcre_get_stringtable_entries()\fP function. The first +argument is the compiled pattern, and the second is the name. The third and +fourth are pointers to variables which are updated by the function. After it +has run, they point to the first and last entries in the name-to-number table +for the given name. The function itself returns the length of each entry, or +PCRE_ERROR_NOSUBSTRING if there are none. The format of the table is described +above in the section entitled \fIInformation about a pattern\fP. Given all the +relevant entries for the name, you can extract each of their numbers, and hence +the captured data, if any. +. +. +.SH "FINDING ALL POSSIBLE MATCHES" +.rs +.sp +The traditional matching function uses a similar algorithm to Perl, which stops +when it finds the first match, starting at a given point in the subject. If you +want to find all possible matches, or the longest possible match, consider +using the alternative matching function (see below) instead. If you cannot use +the alternative function, but still need to find all possible matches, you +can kludge it up by making use of the callout facility, which is described in +the +.\" HREF +\fBpcrecallout\fP +.\" +documentation. +.P +What you have to do is to insert a callout right at the end of the pattern. +When your callout function is called, extract and save the current matched +substring. Then return 1, which forces \fBpcre_exec()\fP to backtrack and try +other alternatives. Ultimately, when it runs out of matches, \fBpcre_exec()\fP +will yield PCRE_ERROR_NOMATCH. +. +. +.\" HTML <a name="dfamatch"></a> +.SH "MATCHING A PATTERN: THE ALTERNATIVE FUNCTION" +.rs +.sp +.B int pcre_dfa_exec(const pcre *\fIcode\fP, "const pcre_extra *\fIextra\fP," +.ti +5n +.B "const char *\fIsubject\fP," int \fIlength\fP, int \fIstartoffset\fP, +.ti +5n +.B int \fIoptions\fP, int *\fIovector\fP, int \fIovecsize\fP, +.ti +5n +.B int *\fIworkspace\fP, int \fIwscount\fP); +.P +The function \fBpcre_dfa_exec()\fP is called to match a subject string against +a compiled pattern, using a "DFA" matching algorithm.

Nevertheless, there are +times when this kind of matching can be useful. For a discussion of the two +matching algorithms, see the +.\" HREF +\fBpcrematching\fP +.\" +documentation. +.P +The arguments for the \fBpcre_dfa_exec()\fP function are the same as for +\fBpcre_exec()\fP, plus two extras.

The other common arguments are used +in the same way as for \fBpcre_exec()\fP, so their description is not repeated +here. +.P +The two additional arguments provide workspace for the function.

All but the last three of these are +the same as for \fBpcre_exec()\fP, so their description is not repeated here. +.sp + PCRE_PARTIAL +.sp +This has the same general effect as it does for \fBpcre_exec()\fP, but the +details are slightly different. When PCRE_PARTIAL is set for +\fBpcre_dfa_exec()\fP, the return code PCRE_ERROR_NOMATCH is converted into +PCRE_ERROR_PARTIAL if the end of the subject is reached, there have been no +complete matches, but there is still at least one matching possibility. The +portion of the string that provided the partial match is set as the first +matching string. +.sp + PCRE_DFA_SHORTEST +.sp +Setting the PCRE_DFA_SHORTEST option causes the matching algorithm to stop as +soon as it has found one match.

The PCRE_DFA_RESTART +option requests this action; when it is set, the \fIworkspace\fP and +\fIwscount\fP options must reference the same vector as before because data +about the match so far is left in them after a partial match.

They are all selected, or deselected, by providing +options to the \fBconfigure\fP script that is run before the \fBmake\fP +command. The complete list of options for \fBconfigure\fP (which includes the +standard ones such as the selection of the installation directory) can be +obtained by running +.sp + ./configure --help +.sp +The following sections describe certain options whose names begin with --enable +or --disable. These settings specify changes to the defaults for the +\fBconfigure\fP command. Because of the way that \fBconfigure\fP works, +--enable and --disable always come in pairs, so the complementary option always +exists as well, but as it specifies the default, it is not described. +. +.SH "C++ SUPPORT" +.rs +.sp +By default, the \fBconfigure\fP script will search for a C++ compiler and C++ +header files. If it finds them, it automatically builds the C++ wrapper library +for PCRE. You can disable this by adding +.sp + --disable-cpp +.sp +to the \fBconfigure\fP command. +. +.SH "UTF-8 SUPPORT" +.rs +.sp +To build PCRE with support for UTF-8 character strings, add +.sp + --enable-utf8 +.sp +to the \fBconfigure\fP command. Of itself, this does not make PCRE treat +strings as UTF-8. As well as compiling PCRE with this option, you also have +have to set the PCRE_UTF8 option when you call the \fBpcre_compile()\fP +function. +. +.SH "UNICODE CHARACTER PROPERTY SUPPORT" +.rs +.sp +UTF-8 support allows PCRE to process character values greater than 255 in the +strings that it handles. On its own, however, it does not provide any +facilities for accessing the properties of such characters. If you want to be +able to use the pattern escapes \eP, \ep, and \eX, which refer to Unicode +character properties, you must add +.sp + --enable-unicode-properties +.sp +to the \fBconfigure\fP command. This implies UTF-8 support, even if you have +not explicitly requested it. +.P +Including Unicode property support adds around 90K of tables to the PCRE +library, approximately doubling its size. Only the general category properties +such as \fILu\fP and \fINd\fP are supported. Details are given in the +.\" HREF +\fBpcrepattern\fP +.\" +documentation. +. +.SH "CODE VALUE OF NEWLINE" +.rs +.sp +By default, PCRE interprets character 10 (linefeed, LF) as indicating the end +of a line. This is the normal newline character on Unix-like systems. You can +compile PCRE to use character 13 (carriage return, CR) instead, by adding +.sp + --enable-newline-is-cr +.sp +to the \fBconfigure\fP command. There is also a --enable-newline-is-lf option, +which explicitly specifies linefeed as the newline character. +.sp +Alternatively, you can specify that line endings are to be indicated by the two +character sequence CRLF. If you want this, add +.sp + --enable-newline-is-crlf +.sp +to the \fBconfigure\fP command. Whatever line ending convention is selected +when PCRE is built can be overridden when the library functions are called. At +build time it is conventional to use the standard for your operating system. +. +.SH "BUILDING SHARED AND STATIC LIBRARIES" +.rs +.sp +The PCRE building process uses \fBlibtool\fP to build both shared and static +Unix libraries by default. You can suppress one of these by adding one of +.sp + --disable-shared + --disable-static +.sp +to the \fBconfigure\fP command, as required. +. +.SH "POSIX MALLOC USAGE" +.rs +.sp +When PCRE is called through the POSIX interface (see the +.\" HREF +\fBpcreposix\fP +.\" +documentation), additional working storage is required for holding the pointers +to capturing substrings, because PCRE requires three integers per substring, +whereas the POSIX interface provides only two. If the number of expected +substrings is small, the wrapper function uses space on the stack, because this +is faster than using \fBmalloc()\fP for each call. The default threshold above +which the stack is no longer used is 10; it can be changed by adding a setting +such as +.sp + --with-posix-malloc-threshold=20 +.sp +to the \fBconfigure\fP command. +. +.SH "HANDLING VERY LARGE PATTERNS" +.rs +.sp +Within a compiled pattern, offset values are used to point from one part to +another (for example, from an opening parenthesis to an alternation +metacharacter). By default, two-byte values are used for these offsets, leading +to a maximum size for a compiled pattern of around 64K. This is sufficient to +handle all but the most gigantic patterns. Nevertheless, some people do want to +process enormous patterns, so it is possible to compile PCRE to use three-byte +or four-byte offsets by adding a setting such as +.sp + --with-link-size=3 +.sp +to the \fBconfigure\fP command. The value given must be 2, 3, or 4. Using +longer offsets slows down the operation of PCRE because it has to load +additional bytes when handling them. +.P +If you build PCRE with an increased link size, test 2 (and test 5 if you are +using UTF-8) will fail. Part of the output of these tests is a representation +of the compiled pattern, and this changes with the link size. +. +.SH "AVOIDING EXCESSIVE STACK USAGE" +.rs +.sp +When matching with the \fBpcre_exec()\fP function, PCRE implements backtracking +by making recursive calls to an internal function called \fBmatch()\fP. In +environments where the size of the stack is limited, this can severely limit +PCRE's operation. (The Unix environment does not usually suffer from this +problem, but it may sometimes be necessary to increase the maximum stack size. +There is a discussion in the +.\" HREF +\fBpcrestack\fP +.\" +documentation.) An alternative approach to recursion that uses memory from the +heap to remember data, instead of using recursive function calls, has been +implemented to work round the problem of limited stack size. If you want to +build a version of PCRE that works this way, add +.sp + --disable-stack-for-recursion +.sp +to the \fBconfigure\fP command. With this configuration, PCRE will use the +\fBpcre_stack_malloc\fP and \fBpcre_stack_free\fP variables to call memory +management functions. Separate functions are provided because the usage is very +predictable: the block sizes requested are always the same, and the blocks are +always freed in reverse order. A calling program might be able to implement +optimized functions that perform better than the standard \fBmalloc()\fP and +\fBfree()\fP functions. PCRE runs noticeably more slowly when built in this +way. This option affects only the \fBpcre_exec()\fP function; it is not +relevant for the the \fBpcre_dfa_exec()\fP function. +. +.SH "LIMITING PCRE RESOURCE USAGE" +.rs +.sp +Internally, PCRE has a function called \fBmatch()\fP, which it calls repeatedly +(sometimes recursively) when matching a pattern with the \fBpcre_exec()\fP +function. By controlling the maximum number of times this function may be +called during a single matching operation, a limit can be placed on the +resources used by a single call to \fBpcre_exec()\fP. The limit can be changed +at run time, as described in the +.\" HREF +\fBpcreapi\fP +.\" +documentation. The default is 10 million, but this can be changed by adding a +setting such as +.sp + --with-match-limit=500000 +.sp +to the \fBconfigure\fP command. This setting has no effect on the +\fBpcre_dfa_exec()\fP matching function. +.P +In some environments it is desirable to limit the depth of recursive calls of +\fBmatch()\fP more strictly than the total number of calls, in order to +restrict the maximum amount of stack (or heap, if --disable-stack-for-recursion +is specified) that is used. A second limit controls this; it defaults to the +value that is set for --with-match-limit, which imposes no additional +constraints. However, you can set a lower limit by adding, for example, +.sp + --with-match-limit-recursion=10000 +.sp +to the \fBconfigure\fP command.

For example, if the pattern is +.sp + ab(?C4)cd +.sp +PCRE knows that any matching string must contain the letter "d".

However, with "abyd", though the result is still +no match, the callout is obeyed. +. +. +.SH "THE CALLOUT INTERFACE" +.rs +.sp +During matching, when PCRE reaches a callout point, the external function +defined by \fIpcre_callout\fP is called (if it is set). This applies to both +the \fBpcre_exec()\fP and the \fBpcre_dfa_exec()\fP matching functions. The +only argument to the callout function is a pointer to a \fBpcre_callout\fP +block.

The initial version was 0; the current version is 1. The version +number will change again in future if additional fields are added, but the +intention is never to remove any of the existing fields. +.P +The \fIcallout_number\fP field contains the number of the callout, as compiled +into the pattern (that is, the number after ?C for manual callouts, and 255 for +automatically generated callouts). +.P +The \fIoffset_vector\fP field is a pointer to the vector of offsets that was +passed by the caller to \fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP. When +\fBpcre_exec()\fP is used, the contents can be inspected in order to extract +substrings that have been matched so far, in the same way as for extracting +substrings after a match has completed. For \fBpcre_dfa_exec()\fP this field is +not useful. +.P +The \fIsubject\fP and \fIsubject_length\fP fields contain copies of the values +that were passed to \fBpcre_exec()\fP. +.P +The \fIstart_match\fP field contains the offset within the subject at which the +current match attempt started. If the pattern is not anchored, the callout +function may be called several times from the same point in the pattern for +different starting points in the subject. +.P +The \fIcurrent_position\fP field contains the offset within the subject of the +current match pointer. +.P +When the \fBpcre_exec()\fP function is used, the \fIcapture_top\fP field +contains one more than the number of the highest numbered captured substring so +far. If no substrings have been captured, the value of \fIcapture_top\fP is +one. This is always the case when \fBpcre_dfa_exec()\fP is used, because it +does not support captured substrings. +.P +The \fIcapture_last\fP field contains the number of the most recently captured +substring.

The differences described here are with respect to Perl +5.8. +.P +1. PCRE has only a subset of Perl's UTF-8 and Unicode support. Details of what +it does have are given in the +.\" HTML <a href="pcre.html#utf8support"> +.\" </a> +section on UTF-8 support +.\" +in the main +.\" HREF +\fBpcre\fP +.\" +page. +.P +2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl permits +them, but they do not mean what you might think. For example, (?!a){3} does +not assert that the next three characters are not "a". It just asserts that the +next character is not "a" three times. +.P +3. Capturing subpatterns that occur inside negative lookahead assertions are +counted, but their entries in the offsets vector are never set. Perl sets its +numerical variables from any such patterns that are matched before the +assertion fails to match something (thereby succeeding), but only if the +negative lookahead assertion contains just one branch. +.P +4. Though binary zero characters are supported in the subject string, they are +not allowed in a pattern string because it is passed as a normal C string, +terminated by zero. The escape sequence \e0 can be used in the pattern to +represent a binary zero. +.P +5. The following Perl escape sequences are not supported: \el, \eu, \eL, +\eU, and \eN. In fact these are implemented by Perl's general string-handling +and are not part of its pattern matching engine. If any of these are +encountered by PCRE, an error is generated. +.P +6. The Perl escape sequences \ep, \eP, and \eX are supported only if PCRE is +built with Unicode character property support. The properties that can be +tested with \ep and \eP are limited to the general category properties such as +Lu and Nd, script names such as Greek or Han, and the derived properties Any +and L&. +.P +7. PCRE does support the \eQ...\eE escape for quoting substrings. Characters in +between are treated as literals. This is slightly different from Perl in that $ +and @ are also handled as literals inside the quotes. In Perl, they cause +variable interpolation (but of course PCRE does not have variables). Note the +following examples: +.sp + Pattern PCRE matches Perl matches +.sp +.\" JOIN + \eQabc$xyz\eE abc$xyz abc followed by the + contents of $xyz + \eQabc\e$xyz\eE abc\e$xyz abc\e$xyz + \eQabc\eE\e$\eQxyz\eE abc$xyz abc$xyz +.sp +The \eQ...\eE sequence is recognized both inside and outside character classes. +.P +8. Fairly obviously, PCRE does not support the (?{code}) and (?p{code}) +constructions. However, there is support for recursive patterns using the +non-Perl items (?R), (?number), and (?P>name). Also, the PCRE "callout" feature +allows an external function to be called during pattern matching. See the +.\" HREF +\fBpcrecallout\fP +.\" +documentation for details. +.P +9. There are some differences that are concerned with the settings of captured +strings when part of a pattern is repeated. For example, matching "aba" against +the pattern /^(a(b)?)+$/ in Perl leaves $2 unset, but in PCRE it is set to "b". +.P +10. PCRE provides some extensions to the Perl regular expression facilities: +.sp +(a) Although lookbehind assertions must match fixed length strings, each +alternative branch of a lookbehind assertion can match a different length of +string. Perl requires them all to have the same length. +.sp +(b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not set, the $ +meta-character matches only at the very end of the string. +.sp +(c) If PCRE_EXTRA is set, a backslash followed by a letter with no special +meaning is faulted. Otherwise, like Perl, the backslash is ignored. (Perl can +be made to issue a warning.) +.sp +(d) If PCRE_UNGREEDY is set, the greediness of the repetition quantifiers is +inverted, that is, by default they are not greedy, but if followed by a +question mark they are. +.sp +(e) PCRE_ANCHORED can be used at matching time to force a pattern to be tried +only at the first matching position in the subject string. +.sp +(f) The PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, and PCRE_NO_AUTO_CAPTURE +options for \fBpcre_exec()\fP have no Perl equivalents. +.sp +(g) The (?R), (?number), and (?P>name) constructs allows for recursive pattern +matching (Perl can do this using the (?p{code}) construct, which PCRE cannot +support.) +.sp +(h) PCRE supports named capturing substrings, using the Python syntax. +.sp +(i) PCRE supports the possessive quantifier "++" syntax, taken from Sun's Java +package. +.sp +(j) The (R) condition, for testing recursion, is a PCRE extension. +.sp +(k) The callout facility is PCRE-specific. +.sp +(l) The partial matching facility is PCRE-specific. +.sp +(m) Patterns compiled by PCRE can be saved and re-used at a later time, even on +different hosts that have the other endianness. +.sp +(n) The alternative matching function (\fBpcre_dfa_exec()\fP) matches in a +different way and is not Perl-compatible. +.P +.in 0 +Last updated: 06 June 2006 +.br +Copyright (c) 1997-2006 University of Cambridge.

If pointer arguments are supplied, it copies matched sub-strings that +match sub-patterns into them. +.sp + Example: successful match + pcrecpp::RE re("h.*o"); + re.FullMatch("hello"); +.sp + Example: unsuccessful match (requires full match): + pcrecpp::RE re("e"); + !re.FullMatch("hello"); +.sp + Example: creating a temporary RE object: + pcrecpp::RE("h.*o").FullMatch("hello"); +.sp +You can pass in a "const char*" or a "string" for "text".

The +examples below use one mode or the other arbitrarily.

"text" matches "pattern" exactly; +.sp + b. The number of matched sub-patterns is >= number of supplied + pointers; +.sp + c. The "i"th argument has a suitable type for holding the + string captured as the "i"th sub-pattern. If you pass in + NULL for the "i"th argument, or pass fewer arguments than + number of sub-patterns, "i"th captured sub-pattern is + ignored. +.sp +The matching interface supports at most 16 arguments per call. +If you need more, consider using the more general interface +\fBpcrecpp::RE::DoMatch\fP. See \fBpcrecpp.h\fP for the signature for +\fBDoMatch\fP. +. +.SH "PARTIAL MATCHES" +.rs +.sp +You can use the "PartialMatch" operation when you want the pattern +to match any substring of the text. +.sp + Example: simple search for a string: + pcrecpp::RE("ell").PartialMatch("hello"); +.sp + Example: find first number in a string: + int number; + pcrecpp::RE re("(\e\ed+)"); + re.PartialMatch("x*100 + 20", &number); + assert(number == 100); +. +. +.SH "UTF-8 AND THE MATCHING INTERFACE" +.rs +.sp +By default, pattern and text are plain text, one byte per character. The UTF8 +flag, passed to the constructor, causes both pattern and string to be treated +as UTF-8 text, still a byte stream but potentially multiple bytes per +character. In practice, the text is likelier to be UTF-8 than the pattern, but +the match returned may depend on the UTF8 flag, so always use it when matching +UTF8 text. For example, "." will match one byte normally but with UTF8 set may +match up to three bytes of a multi-byte character. +.sp + Example: + pcrecpp::RE_Options options; + options.set_utf8(); + pcrecpp::RE re(utf8_pattern, options); + re.FullMatch(utf8_string); +.sp + Example: using the convenience function UTF8(): + pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8()); + re.FullMatch(utf8_string); +.sp +NOTE: The UTF8 flag is ignored if pcre was not configured with the + --enable-utf8 flag. +. +. +.SH "PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE" +.rs +.sp +PCRE defines some modifiers to change the behavior of the regular expression +engine. The C++ wrapper defines an auxiliary class, RE_Options, as a vehicle to +pass such modifiers to a RE class. Currently, the following modifiers are +supported: +.sp + modifier description Perl corresponding +.sp + PCRE_CASELESS case insensitive match /i + PCRE_MULTILINE multiple lines match /m + PCRE_DOTALL dot matches newlines /s + PCRE_DOLLAR_ENDONLY $ matches only at end N/A + PCRE_EXTRA strict escape parsing N/A + PCRE_EXTENDED ignore whitespaces /x + PCRE_UTF8 handles UTF8 chars built-in + PCRE_UNGREEDY reverses * and *? N/A + PCRE_NO_AUTO_CAPTURE disables capturing parens N/A (*) +.sp +(*) Both Perl and PCRE allow non capturing parentheses by means of the +"?:" modifier within the pattern itself. e.g. (?:ab|cd) does not +capture, while (ab|cd) does. +.P +For a full account on how each modifier works, please check the +PCRE API reference page. +.P +For each modifier, there are two member functions whose name is made +out of the modifier in lowercase, without the "PCRE_" prefix. For +instance, PCRE_CASELESS is handled by +.sp + bool caseless() +.sp +which returns true if the modifier is set, and +.sp + RE_Options & set_caseless(bool) +.sp +which sets or unsets the modifier. Moreover, PCRE_EXTRA_MATCH_LIMIT can be +accessed through the \fBset_match_limit()\fR and \fBmatch_limit()\fR member +functions. Setting \fImatch_limit\fR to a non-zero value will limit the +execution of pcre to keep it from doing bad things like blowing the stack or +taking an eternity to return a result. A value of 5000 is good enough to stop +stack blowup in a 2MB thread stack. Setting \fImatch_limit\fR to zero disables +match limiting. Alternatively, you can call \fBmatch_limit_recursion()\fP +which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to limit how much PCRE +recurses. \fBmatch_limit()\fP limits the number of matches PCRE does; +\fBmatch_limit_recursion()\fP limits the depth of internal recursion, and +therefore the amount of stack that is used. +.P +Normally, to pass one or more modifiers to a RE class, you declare +a \fIRE_Options\fR object, set the appropriate options, and pass this +object to a RE constructor. Example: +.sp + RE_options opt; + opt.set_caseless(true); + if (RE("HELLO", opt).PartialMatch("hello world")) ... +.sp +RE_options has two constructors. The default constructor takes no arguments and +creates a set of flags that are off by default. The optional parameter +\fIoption_flags\fR is to facilitate transfer of legacy code from C programs. +This lets you do +.sp + RE(pattern, + RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str); +.sp +However, new code is better off doing +.sp + RE(pattern, + RE_Options().set_caseless(true).set_multiline(true)) + .PartialMatch(str); +.sp +If you are going to pass one of the most used modifiers, there are some +convenience functions that return a RE_Options class with the +appropriate modifier already set: \fBCASELESS()\fR, \fBUTF8()\fR, +\fBMULTILINE()\fR, \fBDOTALL\fR(), and \fBEXTENDED()\fR. +.P +If you need to set several options at once, and you don't want to go through +the pains of declaring a RE_Options object and setting several options, there +is a parallel method that give you such ability on the fly. You can concatenate +several \fBset_xxxxx()\fR member functions, since each of them returns a +reference to its class object. For example, to pass PCRE_CASELESS, +PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one statement, you may write: +.sp + RE(" ^ xyz \e\es+ .* blah$", + RE_Options() + .set_caseless(true) + .set_extended(true) + .set_multiline(true)).PartialMatch(sometext); +.sp +. +. +.SH "SCANNING TEXT INCREMENTALLY" +.rs +.sp +The "Consume" operation may be useful if you want to repeatedly +match regular expressions at the front of a string and skip over +them as they match. This requires use of the "StringPiece" type, +which represents a sub-range of a real string. Like RE, StringPiece +is defined in the pcrecpp namespace. +.sp + Example: read lines of the form "var = value" from a string. + string contents = ...; // Fill string somehow + pcrecpp::StringPiece input(contents); // Wrap in a StringPiece + + string var; + int value; + pcrecpp::RE re("(\e\ew+) = (\e\ed+)\en"); + while (re.Consume(&input, &var, &value)) { + ...; + } +.sp +Each successful call to "Consume" will set "var/value", and also +advance "input" so it points past the matched text. +.P +The "FindAndConsume" operation is similar to "Consume" but does not +anchor your match at the beginning of the string. For example, you +could extract all words from a string by repeatedly calling +.sp + pcrecpp::RE("(\e\ew+)").FindAndConsume(&input, &word) +. +. +.SH "PARSING HEX/OCTAL/C-RADIX NUMBERS" +.rs +.sp +By default, if you pass a pointer to a numeric value, the +corresponding text is interpreted as a base-10 number. You can +instead wrap the pointer with a call to one of the operators Hex(), +Octal(), or CRadix() to interpret the text in another base. The +CRadix operator interprets C-style "0" (base-8) and "0x" (base-16) +prefixes, but defaults to base-10. +.sp + Example: + int a, b, c, d; + pcrecpp::RE re("(.*) (.*) (.*) (.*)"); + re.FullMatch("100 40 0100 0x40", + pcrecpp::Octal(&a), pcrecpp::Hex(&b), + pcrecpp::CRadix(&c), pcrecpp::CRadix(&d)); +.sp +will leave 64 in a, b, c, and d. +. +. +.SH "REPLACING PARTS OF STRINGS" +.rs +.sp +You can replace the first match of "pattern" in "str" with "rewrite". +Within "rewrite", backslash-escaped digits (\e1 to \e9) can be +used to insert text matching corresponding parenthesized group +from the pattern. \e0 in "rewrite" refers to the entire matching +text. For example: +.sp + string s = "yabba dabba doo"; + pcrecpp::RE("b+").Replace("d", &s); +.sp +will leave "s" containing "yada dabba doo". The result is true if the pattern +matches and a replacement occurs, false otherwise. +.P +\fBGlobalReplace\fP is like \fBReplace\fP except that it replaces all +occurrences of the pattern in the string with the rewrite. Replacements are +not subject to re-matching. For example: +.sp + string s = "yabba dabba doo"; + pcrecpp::RE("b+").GlobalReplace("d", &s); +.sp +will leave "s" containing "yada dada doo". It returns the number of +replacements made. +.P +\fBExtract\fP is like \fBReplace\fP, except that if the pattern matches, +"rewrite" is copied into "out" (an additional argument) with substitutions. +The non-matching portions of "text" are ignored. Returns true iff a match +occurred and the extraction happened successfully; if no match occurs, the +string is left unaffected. +. +. +.SH AUTHOR +.rs +.sp +The C++ wrapper was contributed by Google Inc. +.br +Copyright (c) 2005 Google Inc.

However, \fBpcregrep\fP +guarantees to have up to 8K of preceding text available for context output. +.TP +\fB-C\fP \fInumber\fP, \fB--context=\fP\fInumber\fP +Output \fInumber\fP lines of context both before and after each matching line. +This is equivalent to setting both \fB-A\fP and \fB-B\fP to the same value. +.TP +\fB-c\fP, \fB--count\fP +Do not output individual lines; instead just output a count of the number of +lines that would otherwise have been output. If several files are given, a +count is output for each of them. In this mode, the \fB-A\fP, \fB-B\fP, and +\fB-C\fP options are ignored. +.TP +\fB--colour\fP, \fB--color\fP +If this option is given without any data, it is equivalent to "--colour=auto". +If data is required, it must be given in the same shell item, separated by an +equals sign. +.TP +\fB--colour=\fP\fIvalue\fP, \fB--color=\fP\fIvalue\fP +This option specifies under what circumstances the part of a line that matched +a pattern should be coloured in the output. The value may be "never" (the +default), "always", or "auto". In the latter case, colouring happens only if +the standard output is connected to a terminal. The colour can be specified by +setting the environment variable PCREGREP_COLOUR or PCREGREP_COLOR. The value +of this variable should be a string of two numbers, separated by a semicolon. +They are copied directly into the control string for setting colour on a +terminal, so it is your responsibility to ensure that they make sense. If +neither of the environment variables is set, the default is "1;31", which gives +red. +.TP +\fB-D\fP \fIaction\fP, \fB--devices=\fP\fIaction\fP +If an input path is not a regular file or a directory, "action" specifies how +it is to be processed. Valid values are "read" (the default) or "skip" +(silently skip the path). +.TP +\fB-d\fP \fIaction\fP, \fB--directories=\fP\fIaction\fP +If an input path is a directory, "action" specifies how it is to be processed. +Valid values are "read" (the default), "recurse" (equivalent to the \fB-r\fP +option), or "skip" (silently skip the path). In the default case, directories +are read as if they were ordinary files. In some operating systems the effect +of reading a directory like this is an immediate end-of-file. +.TP +\fB-e\fP \fIpattern\fP, \fB--regex=\fP\fIpattern\fP, +\fB--regexp=\fP\fIpattern\fP Specify a pattern to be matched. This option can +be used multiple times in order to specify several patterns. It can also be +used as a way of specifying a single pattern that starts with a hyphen. When +\fB-e\fP is used, no argument pattern is taken from the command line; all +arguments are treated as file names. There is an overall maximum of 100 +patterns. They are applied to each line in the order in which they are defined +until one matches (or fails to match if \fB-v\fP is used). If \fB-f\fP is used +with \fB-e\fP, the command line patterns are matched first, followed by the +patterns from the file, independent of the order in which these options are +specified. Note that multiple use of \fB-e\fP is not the same as a single +pattern with alternatives. For example, X|Y finds the first character in a line +that is X or Y, whereas if the two patterns are given separately, +\fBpcregrep\fP finds X if it is present, even if it follows Y in the line. It +finds Y only if there is no X in the line. This really matters only if you are +using \fB-o\fP to show the portion of the line that matched. +.TP +\fB--exclude\fP=\fIpattern\fP +When \fBpcregrep\fP is searching the files in a directory as a consequence of +the \fB-r\fP (recursive search) option, any files whose names match the pattern +are excluded. The pattern is a PCRE regular expression. If a file name matches +both \fB--include\fP and \fB--exclude\fP, it is excluded. There is no short +form for this option. +.TP +\fB-F\fP, \fB--fixed-strings\fP +Interpret each pattern as a list of fixed strings, separated by newlines, +instead of as a regular expression. The \fB-w\fP (match as a word) and \fB-x\fP +(match whole line) options can be used with \fB-F\fP. They apply to each of the +fixed strings. A line is selected if any of the fixed strings are found in it +(subject to \fB-w\fP or \fB-x\fP, if present). +.TP +\fB-f\fP \fIfilename\fP, \fB--file=\fP\fIfilename\fP +Read a number of patterns from the file, one per line, and match them against +each line of input. A data line is output if any of the patterns match it. The +filename can be given as "-" to refer to the standard input. When \fB-f\fP is +used, patterns specified on the command line using \fB-e\fP may also be +present; they are tested before the file's patterns. However, no other pattern +is taken from the command line; all arguments are treated as file names. There +is an overall maximum of 100 patterns. Trailing white space is removed from +each line, and blank lines are ignored. An empty file contains no patterns and +therefore matches nothing. +.TP +\fB-H\fP, \fB--with-filename\fP +Force the inclusion of the filename at the start of output lines when searching +a single file. By default, the filename is not shown in this case. For matching +lines, the filename is followed by a colon and a space; for context lines, a +hyphen separator is used. If a line number is also being output, it follows the +file name without a space. +.TP +\fB-h\fP, \fB--no-filename\fP +Suppress the output filenames when searching multiple files. By default, +filenames are shown when multiple files are searched. For matching lines, the +filename is followed by a colon and a space; for context lines, a hyphen +separator is used. If a line number is also being output, it follows the file +name without a space. +.TP +\fB--help\fP +Output a brief help message and exit. +.TP +\fB-i\fP, \fB--ignore-case\fP +Ignore upper/lower case distinctions during comparisons. +.TP +\fB--include\fP=\fIpattern\fP +When \fBpcregrep\fP is searching the files in a directory as a consequence of +the \fB-r\fP (recursive search) option, only those files whose names match the +pattern are included. The pattern is a PCRE regular expression. If a file name +matches both \fB--include\fP and \fB--exclude\fP, it is excluded. There is no +short form for this option. +.TP +\fB-L\fP, \fB--files-without-match\fP +Instead of outputting lines from the files, just output the names of the files +that do not contain any lines that would have been output. Each file name is +output once, on a separate line. +.TP +\fB-l\fP, \fB--files-with-matches\fP +Instead of outputting lines from the files, just output the names of the files +containing lines that would have been output. Each file name is output +once, on a separate line. Searching stops as soon as a matching line is found +in a file. +.TP +\fB--label\fP=\fIname\fP +This option supplies a name to be used for the standard input when file names +are being output. If not supplied, "(standard input)" is used. There is no +short form for this option. +.TP +\fB--locale\fP=\fIlocale-name\fP +This option specifies a locale to be used for pattern matching. It overrides +the value in the \fBLC_ALL\fP or \fBLC_CTYPE\fP environment variables. If no +locale is specified, the PCRE library's default (usually the "C" locale) is +used. There is no short form for this option. +.TP +\fB-M\fP, \fB--multiline\fP +Allow patterns to match more than one line. When this option is given, patterns +may usefully contain literal newline characters and internal occurrences of ^ +and $ characters. The output for any one match may consist of more than one +line. When this option is set, the PCRE library is called in "multiline" mode. +There is a limit to the number of lines that can be matched, imposed by the way +that \fBpcregrep\fP buffers the input file as it scans it. However, +\fBpcregrep\fP ensures that at least 8K characters or the rest of the document +(whichever is the shorter) are available for forward matching, and similarly +the previous 8K characters (or all the previous characters, if fewer than 8K) +are guaranteed to be available for lookbehind assertions. +.TP +\fB-N\fP \fInewline-type\fP, \fB--newline=\fP\fInewline-type\fP +The PCRE library supports three different character sequences for indicating +the ends of lines. They are the single-character sequences CR (carriage return) +and LF (linefeed), and the two-character sequence CR, LF. When the library is +built, a default line-ending sequence is specified. This is normally the +standard sequence for the operating system. Unless otherwise specified by this +option, \fBpcregrep\fP uses the default. The possible values for this option +are CR, LF, or CRLF. This makes it possible to use \fBpcregrep\fP on files that +have come from other environments without having to modify their line endings. +If the data that is being scanned does not agree with the convention set by +this option, \fBpcregrep\fP may behave in strange ways. +.TP +\fB-n\fP, \fB--line-number\fP +Precede each output line by its line number in the file, followed by a colon +and a space for matching lines or a hyphen and a space for context lines. If +the filename is also being output, it precedes the line number. +.TP +\fB-o\fP, \fB--only-matching\fP +Show only the part of the line that matched a pattern. In this mode, no +context is shown. That is, the \fB-A\fP, \fB-B\fP, and \fB-C\fP options are +ignored. +.TP +\fB-q\fP, \fB--quiet\fP +Work quietly, that is, display nothing except error messages. The exit +status indicates whether or not any matches were found. +.TP +\fB-r\fP, \fB--recursive\fP +If any given path is a directory, recursively scan the files it contains, +taking note of any \fB--include\fP and \fB--exclude\fP settings. By default, a +directory is read as a normal file; in some operating systems this gives an +immediate end-of-file. This option is a shorthand for setting the \fB-d\fP +option to "recurse". +.TP +\fB-s\fP, \fB--no-messages\fP +Suppress error messages about non-existent or unreadable files. Such files are +quietly skipped. However, the return code is still 2, even if matches were +found in other files. +.TP +\fB-u\fP, \fB--utf-8\fP +Operate in UTF-8 mode. This option is available only if PCRE has been compiled +with UTF-8 support. Both patterns and subject lines must be valid strings of +UTF-8 characters. +.TP +\fB-V\fP, \fB--version\fP +Write the version numbers of \fBpcregrep\fP and the PCRE library that is being +used to the standard error stream. +.TP +\fB-v\fP, \fB--invert-match\fP +Invert the sense of the match, so that lines which do \fInot\fP match any of +the patterns are the ones that are found. +.TP +\fB-w\fP, \fB--word-regex\fP, \fB--word-regexp\fP +Force the patterns to match only whole words. This is equivalent to having \eb +at the start and end of the pattern. +.TP +\fB-x\fP, \fB--line-regex\fP, \fP--line-regexp\fP +Force the patterns to be anchored (each must start matching at the beginning of +a line) and in addition, require them to match entire lines. This is +equivalent to having ^ and $ characters at the start and end of each +alternative branch in every pattern. +. +. +.SH "ENVIRONMENT VARIABLES" +.rs +.sp +The environment variables \fBLC_ALL\fP and \fBLC_CTYPE\fP are examined, in that +order, for a locale. The first one that is set is used. This can be overridden +by the \fB--locale\fP option. If no locale is set, the PCRE library's default +(usually the "C" locale) is used. +. +. +.SH "NEWLINES" +.rs +.sp +The \fB-N\fP (\fB--newline\fP) option allows \fBpcregrep\fP to scan files with +different newline conventions from the default. However, the setting of this +option does not affect the way in which \fBpcregrep\fP writes information to +the standard error and output streams. It uses the string "\en" in C +\fBprintf()\fP calls to indicate newlines, relying on the C I/O library to +convert this to an appropriate sequence if the output is sent to a file. +. +. +.SH "OPTIONS COMPATIBILITY" +.rs +.sp +The majority of short and long forms of \fBpcregrep\fP's options are the same +as in the GNU \fBgrep\fP program. Any long option of the form +\fB--xxx-regexp\fP (GNU terminology) is also available as \fB--xxx-regex\fP +(PCRE terminology). However, the \fB--locale\fP, \fB-M\fP, \fB--multiline\fP, +\fB-u\fP, and \fB--utf-8\fP options are specific to \fBpcregrep\fP. +. +. +.SH "OPTIONS WITH DATA" +.rs +.sp +There are four different ways in which an option with data can be specified. +If a short form option is used, the data may follow immediately, or in the next +command line item. For example: +.sp + -f/some/file + -f /some/file +.sp +If a long form option is used, the data may appear in the same command line +item, separated by an equals character, or (with one exception) it may appear +in the next command line item. For example: +.sp + --file=/some/file + --file /some/file +.sp +Note, however, that if you want to supply a file name beginning with ~ as data +in a shell command, and have the shell expand ~ to a home directory, you must +separate the file name from the option, because the shell does not treat ~ +specially unless it is at the start of an item. +.P +The exception to the above is the \fB--colour\fP (or \fB--color\fP) option, +for which the data is optional. If this option does have data, it must be given +in the first form, using an equals character. Otherwise it will be assumed that +it has no data. +. +. +.SH MATCHING ERRORS +.rs +.sp +It is possible to supply a regular expression that takes a very long time to +fail to match certain lines. Such patterns normally involve nested indefinite +repeats, for example: (a+)*\ed when matched against a line of a's with no final +digit. The PCRE matching function has a resource limit that causes it to abort +in these circumstances. If this happens, \fBpcregrep\fP outputs an error +message and the line that caused the problem to the standard error stream. If +there are more than 20 such errors, \fBpcregrep\fP gives up. +. +. +.SH DIAGNOSTICS +.rs +.sp +Exit status is 0 if any matches were found, 1 if no matches were found, and 2 +for syntax errors and non-existent or inacessible files (even if matches were +found in other files) or too many matching errors. Using the \fB-s\fP option to +suppress error messages about inaccessble files does not affect the return +code. +. +. +.SH AUTHOR +.rs +.sp +Philip Hazel +.br +University Computing Service +.br +Cambridge CB2 3QG, England. +.P +.in 0 +Last updated: 06 June 2006 +.br +Copyright (c) 1997-2006 University of Cambridge.

See pcrepattern for a full description of syntax and semantics + of the regular expressions that PCRE supports. + + Patterns, whether supplied on the command line or in a separate file, + are given without delimiters. For example: + + pcregrep Thursday /etc/motd + + If you attempt to use delimiters (for example, by surrounding a pattern + with slashes, as is common in Perl scripts), they are interpreted as + part of the pattern. Quotes can of course be used on the command line + because they are interpreted by the shell, and indeed they are required + if a pattern contains white space or shell metacharacters. + + The first argument that follows any option settings is treated as the + single pattern to be matched when neither -e nor -f is present. Con- + versely, when one or both of these options are used to specify pat- + terns, all arguments are treated as path names. At least one of -e, -f, + or an argument pattern must be provided. + + If no files are specified, pcregrep reads the standard input. The stan- + dard input can also be referenced by a name consisting of a single + hyphen. For example: + + pcregrep some-pattern /file1 - /file3 + + By default, each line that matches the pattern is copied to the stan- + dard output, and if there is more than one file, the file name is out- + put at the start of each line. However, there are options that can + change how pcregrep behaves. In particular, the -M option makes it pos- + sible to search for patterns that span line boundaries. What defines a + line boundary is controlled by the -N (--newline) option. + + Patterns are limited to 8K or BUFSIZ characters, whichever is the + greater. BUFSIZ is defined in <stdio.h>. + + If the LC_ALL or LC_CTYPE environment variable is set, pcregrep uses + the value to set a locale when calling the PCRE library. The --locale + option can be used to override this. + + +OPTIONS + + -- This terminate the list of options. It is useful if the next + item on the command line starts with a hyphen but is not an + option. This allows for the processing of patterns and file- + names that start with hyphens. + + -A number, --after-context=number + Output number lines of context after each matching line. If + filenames and/or line numbers are being output, a hyphen sep- + arator is used instead of a colon for the context lines. A + line containing "--" is output between each group of lines, + unless they are in fact contiguous in the input file. The + value of number is expected to be relatively small. However, + pcregrep guarantees to have up to 8K of following text avail- + able for context output. + + -B number, --before-context=number + Output number lines of context before each matching line. If + filenames and/or line numbers are being output, a hyphen sep- + arator is used instead of a colon for the context lines. A + line containing "--" is output between each group of lines, + unless they are in fact contiguous in the input file. The + value of number is expected to be relatively small. However, + pcregrep guarantees to have up to 8K of preceding text avail- + able for context output. + + -C number, --context=number + Output number lines of context both before and after each + matching line. This is equivalent to setting both -A and -B + to the same value. + + -c, --count + Do not output individual lines; instead just output a count + of the number of lines that would otherwise have been output. + If several files are given, a count is output for each of + them. In this mode, the -A, -B, and -C options are ignored. + + --colour, --color + If this option is given without any data, it is equivalent to + "--colour=auto". If data is required, it must be given in + the same shell item, separated by an equals sign. + + --colour=value, --color=value + This option specifies under what circumstances the part of a + line that matched a pattern should be coloured in the output. + The value may be "never" (the default), "always", or "auto". + In the latter case, colouring happens only if the standard + output is connected to a terminal. The colour can be speci- + fied by setting the environment variable PCREGREP_COLOUR or + PCREGREP_COLOR. The value of this variable should be a string + of two numbers, separated by a semicolon. They are copied + directly into the control string for setting colour on a ter- + minal, so it is your responsibility to ensure that they make + sense. If neither of the environment variables is set, the + default is "1;31", which gives red. + + -D action, --devices=action + If an input path is not a regular file or a directory, + "action" specifies how it is to be processed. Valid values + are "read" (the default) or "skip" (silently skip the path). + + -d action, --directories=action + If an input path is a directory, "action" specifies how it is + to be processed. Valid values are "read" (the default), + "recurse" (equivalent to the -r option), or "skip" (silently + skip the path). In the default case, directories are read as + if they were ordinary files. In some operating systems the + effect of reading a directory like this is an immediate end- + of-file. + + -e pattern, --regex=pattern, + --regexp=pattern Specify a pattern to be matched. This option + can be used multiple times in order to specify several pat- + terns. It can also be used as a way of specifying a single + pattern that starts with a hyphen. When -e is used, no argu- + ment pattern is taken from the command line; all arguments + are treated as file names. There is an overall maximum of 100 + patterns. They are applied to each line in the order in which + they are defined until one matches (or fails to match if -v + is used). If -f is used with -e, the command line patterns + are matched first, followed by the patterns from the file, + independent of the order in which these options are speci- + fied. Note that multiple use of -e is not the same as a sin- + gle pattern with alternatives. For example, X|Y finds the + first character in a line that is X or Y, whereas if the two + patterns are given separately, pcregrep finds X if it is + present, even if it follows Y in the line. It finds Y only if + there is no X in the line. This really matters only if you + are using -o to show the portion of the line that matched. + + --exclude=pattern + When pcregrep is searching the files in a directory as a con- + sequence of the -r (recursive search) option, any files whose + names match the pattern are excluded. The pattern is a PCRE + regular expression. If a file name matches both --include and + --exclude, it is excluded. There is no short form for this + option. + + -F, --fixed-strings + Interpret each pattern as a list of fixed strings, separated + by newlines, instead of as a regular expression. The -w + (match as a word) and -x (match whole line) options can be + used with -F. They apply to each of the fixed strings. A line + is selected if any of the fixed strings are found in it (sub- + ject to -w or -x, if present). + + -f filename, --file=filename + Read a number of patterns from the file, one per line, and + match them against each line of input. A data line is output + if any of the patterns match it. The filename can be given as + "-" to refer to the standard input. When -f is used, patterns + specified on the command line using -e may also be present; + they are tested before the file's patterns. However, no other + pattern is taken from the command line; all arguments are + treated as file names. There is an overall maximum of 100 + patterns. Trailing white space is removed from each line, and + blank lines are ignored. An empty file contains no patterns + and therefore matches nothing. + + -H, --with-filename + Force the inclusion of the filename at the start of output + lines when searching a single file. By default, the filename + is not shown in this case. For matching lines, the filename + is followed by a colon and a space; for context lines, a + hyphen separator is used. If a line number is also being out- + put, it follows the file name without a space. + + -h, --no-filename + Suppress the output filenames when searching multiple files. + By default, filenames are shown when multiple files are + searched. For matching lines, the filename is followed by a + colon and a space; for context lines, a hyphen separator is + used. If a line number is also being output, it follows the + file name without a space. + + --help Output a brief help message and exit. + + -i, --ignore-case + Ignore upper/lower case distinctions during comparisons. + + --include=pattern + When pcregrep is searching the files in a directory as a con- + sequence of the -r (recursive search) option, only those + files whose names match the pattern are included. The pattern + is a PCRE regular expression. If a file name matches both + --include and --exclude, it is excluded. There is no short + form for this option. + + -L, --files-without-match + Instead of outputting lines from the files, just output the + names of the files that do not contain any lines that would + have been output. Each file name is output once, on a sepa- + rate line. + + -l, --files-with-matches + Instead of outputting lines from the files, just output the + names of the files containing lines that would have been out- + put. Each file name is output once, on a separate line. + Searching stops as soon as a matching line is found in a + file. + + --label=name + This option supplies a name to be used for the standard input + when file names are being output. If not supplied, "(standard + input)" is used. There is no short form for this option. + + --locale=locale-name + This option specifies a locale to be used for pattern match- + ing. It overrides the value in the LC_ALL or LC_CTYPE envi- + ronment variables. If no locale is specified, the PCRE + library's default (usually the "C" locale) is used. There is + no short form for this option. + + -M, --multiline + Allow patterns to match more than one line. When this option + is given, patterns may usefully contain literal newline char- + acters and internal occurrences of ^ and $ characters. The + output for any one match may consist of more than one line. + When this option is set, the PCRE library is called in "mul- + tiline" mode. There is a limit to the number of lines that + can be matched, imposed by the way that pcregrep buffers the + input file as it scans it. However, pcregrep ensures that at + least 8K characters or the rest of the document (whichever is + the shorter) are available for forward matching, and simi- + larly the previous 8K characters (or all the previous charac- + ters, if fewer than 8K) are guaranteed to be available for + lookbehind assertions. + + -N newline-type, --newline=newline-type + The PCRE library supports three different character sequences + for indicating the ends of lines. They are the single-charac- + ter sequences CR (carriage return) and LF (linefeed), and the + two-character sequence CR, LF. When the library is built, a + default line-ending sequence is specified. This is normally + the standard sequence for the operating system. Unless other- + wise specified by this option, pcregrep uses the default. The + possible values for this option are CR, LF, or CRLF. This + makes it possible to use pcregrep on files that have come + from other environments without having to modify their line + endings. If the data that is being scanned does not agree + with the convention set by this option, pcregrep may behave + in strange ways. + + -n, --line-number + Precede each output line by its line number in the file, fol- + lowed by a colon and a space for matching lines or a hyphen + and a space for context lines. If the filename is also being + output, it precedes the line number. + + -o, --only-matching + Show only the part of the line that matched a pattern. In + this mode, no context is shown. That is, the -A, -B, and -C + options are ignored. + + -q, --quiet + Work quietly, that is, display nothing except error messages. + The exit status indicates whether or not any matches were + found. + + -r, --recursive + If any given path is a directory, recursively scan the files + it contains, taking note of any --include and --exclude set- + tings. By default, a directory is read as a normal file; in + some operating systems this gives an immediate end-of-file. + This option is a shorthand for setting the -d option to + "recurse". + + -s, --no-messages + Suppress error messages about non-existent or unreadable + files. Such files are quietly skipped. However, the return + code is still 2, even if matches were found in other files. + + -u, --utf-8 + Operate in UTF-8 mode. This option is available only if PCRE + has been compiled with UTF-8 support. Both patterns and sub- + ject lines must be valid strings of UTF-8 characters. + + -V, --version + Write the version numbers of pcregrep and the PCRE library + that is being used to the standard error stream. + + -v, --invert-match + Invert the sense of the match, so that lines which do not + match any of the patterns are the ones that are found. + + -w, --word-regex, --word-regexp + Force the patterns to match only whole words. This is equiva- + lent to having \b at the start and end of the pattern. + + -x, --line-regex, --line-regexp + Force the patterns to be anchored (each must start matching + at the beginning of a line) and in addition, require them to + match entire lines. This is equivalent to having ^ and $ + characters at the start and end of each alternative branch in + every pattern. + + +ENVIRONMENT VARIABLES + + The environment variables LC_ALL and LC_CTYPE are examined, in that + order, for a locale. The first one that is set is used. This can be + overridden by the --locale option. If no locale is set, the PCRE + library's default (usually the "C" locale) is used. + + +NEWLINES + + The -N (--newline) option allows pcregrep to scan files with different + newline conventions from the default. However, the setting of this + option does not affect the way in which pcregrep writes information to + the standard error and output streams. It uses the string "\n" in C + printf() calls to indicate newlines, relying on the C I/O library to + convert this to an appropriate sequence if the output is sent to a + file. + + +OPTIONS COMPATIBILITY + + The majority of short and long forms of pcregrep's options are the same + as in the GNU grep program. Any long option of the form --xxx-regexp + (GNU terminology) is also available as --xxx-regex (PCRE terminology). + However, the --locale, -M, --multiline, -u, and --utf-8 options are + specific to pcregrep. + + +OPTIONS WITH DATA + + There are four different ways in which an option with data can be spec- + ified.

The +"standard" algorithm is the one provided by the \fBpcre_exec()\fP function. +This works in the same was as Perl's matching function, and provides a +Perl-compatible matching operation. +.P +An alternative algorithm is provided by the \fBpcre_dfa_exec()\fP function; +this operates in a different way, and is not Perl-compatible. It has advantages +and disadvantages compared with the standard algorithm, and these are described +below. +.P +When there is only one possible way in which a given subject string can match a +pattern, the two algorithms give the same answer. A difference arises, however, +when there are multiple possibilities. For example, if the pattern +.sp + ^<.*> +.sp +is matched against the string +.sp + <something> <something else> <something further> +.sp +there are three possible answers. The standard algorithm finds only one of +them, whereas the DFA algorithm finds all three. +. +.SH "REGULAR EXPRESSIONS AS TREES" +.rs +.sp +The set of strings that are matched by a regular expression can be represented +as a tree structure. An unlimited repetition in the pattern makes the tree of +infinite size, but it is still a tree. Matching the pattern to a given subject +string (from a given starting point) can be thought of as a search of the tree. +There are two ways to search a tree: depth-first and breadth-first, and these +correspond to the two matching algorithms provided by PCRE. +. +.SH "THE STANDARD MATCHING ALGORITHM" +.rs +.sp +In the terminology of Jeffrey Friedl's book \fIMastering Regular +Expressions\fP, the standard algorithm is an "NFA algorithm". It conducts a +depth-first search of the pattern tree. That is, it proceeds along a single +path through the tree, checking that the subject matches what is required. When +there is a mismatch, the algorithm tries any alternatives at the current point, +and if they all fail, it backs up to the previous branch point in the tree, and +tries the next alternative branch at that level. This often involves backing up +(moving to the left) in the subject string as well. The order in which +repetition branches are tried is controlled by the greedy or ungreedy nature of +the quantifier. +.P +If a leaf node is reached, a matching string has been found, and at that point +the algorithm stops. Thus, if there is more than one possible match, this +algorithm returns the first one that it finds. Whether this is the shortest, +the longest, or some intermediate length depends on the way the greedy and +ungreedy repetition quantifiers are specified in the pattern. +.P +Because it ends up with a single path through the tree, it is relatively +straightforward for this algorithm to keep track of the substrings that are +matched by portions of the pattern in parentheses. This provides support for +capturing parentheses and back references. +. +.SH "THE DFA MATCHING ALGORITHM" +.rs +.sp +DFA stands for "deterministic finite automaton", but you do not need to +understand the origins of that name. This algorithm conducts a breadth-first +search of the tree. Starting from the first matching point in the subject, it +scans the subject string from left to right, once, character by character, and +as it does this, it remembers all the paths through the tree that represent +valid matches. +.P +The scan continues until either the end of the subject is reached, or there are +no more unterminated paths. At this point, terminated paths represent the +different matching possibilities (if there are none, the match has failed). +Thus, if there is more than one possible match, this algorithm finds all of +them, and in particular, it finds the longest. In PCRE, there is an option to +stop the algorithm after the first match (which is necessarily the shortest) +has been found. +.P +Note that all the matches that are found start at the same point in the +subject. If the pattern +.sp + cat(er(pillar)?) +.sp +is matched against the string "the caterpillar catchment", the result will be +the three strings "cat", "cater", and "caterpillar" that start at the fourth +character of the subject. The algorithm does not automatically move on to find +matches that start at later positions. +.P +There are a number of features of PCRE regular expressions that are not +supported by the DFA matching algorithm. They are as follows: +.P +1. Because the algorithm finds all possible matches, the greedy or ungreedy +nature of repetition quantifiers is not relevant. Greedy and ungreedy +quantifiers are treated in exactly the same way. +.P +2. When dealing with multiple paths through the tree simultaneously, it is not +straightforward to keep track of captured substrings for the different matching +possibilities, and PCRE's implementation of this algorithm does not attempt to +do this. This means that no captured substrings are available. +.P +3. Because no substrings are captured, back references within the pattern are +not supported, and cause errors if encountered. +.P +4. For the same reason, conditional expressions that use a backreference as the +condition are not supported. +.P +5. Callouts are supported, but the value of the \fIcapture_top\fP field is +always 1, and the value of the \fIcapture_last\fP field is always -1. +.P +6. +The \eC escape sequence, which (in the standard algorithm) matches a single +byte, even in UTF-8 mode, is not supported because the DFA algorithm moves +through the subject string one character at a time, for all active paths +through the tree. +. +.SH "ADVANTAGES OF THE DFA ALGORITHM" +.rs +.sp +Using the DFA matching algorithm provides the following advantages: +.P +1. All possible matches (at a single point in the subject) are automatically +found, and in particular, the longest match is found. To find more than one +match using the standard algorithm, you have to do kludgy things with +callouts. +.P +2. There is much better support for partial matching. The restrictions on the +content of the pattern that apply when using the standard algorithm for partial +matching do not apply to the DFA algorithm. For non-anchored patterns, the +starting position of a partial match is available. +.P +3. Because the DFA algorithm scans the subject string just once, and never +needs to backtrack, it is possible to pass very long subject strings to the +matching function in several pieces, checking for partial matching each time. +. +.SH "DISADVANTAGES OF THE DFA ALGORITHM" +.rs +.sp +The DFA algorithm suffers from a number of disadvantages: +.P +1. It is substantially slower than the standard algorithm. This is partly +because it has to search for all possible matches, but is also because it is +less susceptible to optimization. +.P +2. Capturing parentheses and back references are not supported. +.P +3. The "atomic group" feature of PCRE regular expressions is supported, but +does not provide the advantage that it does for the standard algorithm. +.P +.in 0 +Last updated: 06 June 2006 +.br +Copyright (c) 1997-2006 University of Cambridge.

When this flag is set for \fBpcre_exec()\fP, the return +code PCRE_ERROR_NOMATCH is converted into PCRE_ERROR_PARTIAL if at any time +during the matching process the last part of the subject string matched part of +the pattern.

The portion of the string that provided the +partial match is set as the first matching string. +.P +Using PCRE_PARTIAL disables one of PCRE's optimizations. PCRE remembers the +last literal byte in a pattern, and abandons matching immediately if such a +byte is not present in the subject string. This optimization cannot be used +for a subject string that might match only partially. +. +. +.SH "RESTRICTED PATTERNS FOR PCRE_PARTIAL" +.rs +.sp +Because of the way certain internal optimizations are implemented in the +\fBpcre_exec()\fP function, the PCRE_PARTIAL option cannot be used with all +patterns. These restrictions do not apply when \fBpcre_dfa_exec()\fP is used. +For \fBpcre_exec()\fP, repeated single characters such as +.sp + a{2,4} +.sp +and repeated single metasequences such as +.sp + \ed+ +.sp +are not permitted if the maximum number of occurrences is greater than one. +Optional items such as \ed?

Here is a run of \fBpcretest\fP that +uses the date example quoted above: +.sp + re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/ + data> 25jun04\eP + 0: 25jun04 + 1: jun + data> 25dec3\eP + Partial match + data> 3ju\eP + Partial match + data> 3juj\eP + No match + data> j\eP + No match +.sp +The first data string is matched completely, so \fBpcretest\fP shows the +matched substrings. The remaining four strings do not match the complete +pattern, but the first two are partial matches. The same test, using DFA +matching (by means of the \eD escape sequence), produces the following output: +.sp + re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/ + data> 25jun04\eP\eD + 0: 25jun04 + data> 23dec3\eP\eD + Partial match: 23dec3 + data> 3ju\eP\eD + Partial match: 3ju + data> 3juj\eP\eD + No match + data> j\eP\eD + No match +.sp +Notice that in this case the portion of the string that was matched is made +available. +. +. +.SH "MULTI-SEGMENT MATCHING WITH pcre_dfa_exec()" +.rs +.sp +When a partial match has been found using \fBpcre_dfa_exec()\fP, it is possible +to continue the match by providing additional subject data and calling +\fBpcre_dfa_exec()\fP again with the PCRE_DFA_RESTART option and the same +working space (where details of the previous partial match are stored). Here is +an example using \fBpcretest\fP, where the \eR escape sequence sets the +PCRE_DFA_RESTART option and the \eD escape sequence requests the use of +\fBpcre_dfa_exec()\fP: +.sp + re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/ + data> 23ja\eP\eD + Partial match: 23ja + data> n05\eR\eD + 0: n05 +.sp +The first call has "23ja" as the subject, and requests partial matching; the +second call has "n05" as the subject for the continued (restarted) match. +Notice that when the match is complete, only the last part is shown; PCRE does +not retain the previously partially-matched string. It is up to the calling +program to do that if it needs to. +.P +This facility can be used to pass very long subject strings to +\fBpcre_dfa_exec()\fP. However, some care is needed for certain types of +pattern. +.P +1. If the pattern contains tests for the beginning or end of a line, you need +to pass the PCRE_NOTBOL or PCRE_NOTEOL options, as appropriate, when the +subject string for any call does not contain the beginning or end of a line. +.P +2. If the pattern contains backward assertions (including \eb or \eB), you need +to arrange for some overlap in the subject strings to allow for this. For +example, you could pass the subject in chunks that were 500 bytes long, but in +a buffer of 700 bytes, with the starting offset set to 200 and the previous 200 +bytes at the start of the buffer. +.P +3. Matching a subject string that is split into multiple segments does not +always produce exactly the same result as matching over one single long string. +The difference arises when there are multiple matching possibilities, because a +partial match result is given only when there are no completed matches in a +call to fBpcre_dfa_exec()\fP. This means that as soon as the shortest match has +been found, continuation to a new subject segment is no longer possible. +Consider this \fBpcretest\fP example: +.sp + re> /dog(sbody)?/ + data> do\eP\eD + Partial match: do + data> gsb\eR\eP\eD + 0: g + data> dogsbody\eD + 0: dogsbody + 1: dog +.sp +The pattern matches the words "dog" or "dogsbody". When the subject is +presented in several parts ("do" and "gsb" being the first two) the match stops +when "dog" has been found, and it is not possible to continue. On the other +hand, if "dogsbody" is presented as a single string, both matches are found. +.P +Because of this phenomenon, it does not usually make sense to end a pattern +that is going to be matched in this way with a variable repeat. +.P +4. Patterns that contain alternatives at the top level which do not all +start with the same pattern item may not work as expected. For example, +consider this pattern: +.sp + 1234|3789 +.sp +If the first part of the subject is "ABC123", a partial match of the first +alternative is found at offset 3. There is no partial match for the second +alternative, because such a match does not start at the same point in the +subject string. Attempting to continue with the string "789" does not yield a +match because only those alternatives that match at one point in the subject +are remembered. The problem arises because the start of the second alternative +matches within the first alternative. There is no problem with anchored +patterns or patterns such as: +.sp + 1234|ABCD +.sp +where no string can be a partial match for both alternatives. +. +. +.P +.in 0 +Last updated: 16 January 2006 +.br +Copyright (c) 1997-2006 University of Cambridge.

This description of PCRE's regular +expressions is intended as reference material. +.P +The original operation of PCRE was on strings of one-byte characters. However, +there is now also support for UTF-8 character strings. To use this, you must +build PCRE to include UTF-8 support, and then call \fBpcre_compile()\fP with +the PCRE_UTF8 option. How this affects pattern matching is mentioned in several +places below. There is also a summary of UTF-8 features in the +.\" HTML <a href="pcre.html#utf8support"> +.\" </a> +section on UTF-8 support +.\" +in the main +.\" HREF +\fBpcre\fP +.\" +page. +.P +The remainder of this document discusses the patterns that are supported by +PCRE when its main matching function, \fBpcre_exec()\fP, is used. +From release 6.0, PCRE offers a second matching function, +\fBpcre_dfa_exec()\fP, which matches using a different algorithm that is not +Perl-compatible. The advantages and disadvantages of the alternative function, +and how it differs from the normal function, are discussed in the +.\" HREF +\fBpcrematching\fP +.\" +page. +.P +A regular expression is a pattern that is matched against a subject string from +left to right. Most characters stand for themselves in a pattern, and match the +corresponding characters in the subject. As a trivial example, the pattern +.sp + The quick brown fox +.sp +matches a portion of a subject string that is identical to itself. When +caseless matching is specified (the PCRE_CASELESS option), letters are matched +independently of case. In UTF-8 mode, PCRE always understands the concept of +case for characters whose values are less than 128, so caseless matching is +always possible. For characters with higher values, the concept of case is +supported if PCRE is compiled with Unicode property support, but not otherwise. +If you want to use caseless matching for characters 128 and above, you must +ensure that PCRE is compiled with Unicode property support as well as with +UTF-8 support. +.P +The power of regular expressions comes from the ability to include alternatives +and repetitions in the pattern. These are encoded in the pattern by the use of +\fImetacharacters\fP, which do not stand for themselves but instead are +interpreted in some special way. +.P +There are two different sets of metacharacters: those that are recognized +anywhere in the pattern except within square brackets, and those that are +recognized in square brackets. Outside square brackets, the metacharacters are +as follows: +.sp + \e general escape character with several uses + ^ assert start of string (or line, in multiline mode) + $ assert end of string (or line, in multiline mode) + . match any character except newline (by default) + [ start character class definition + | start of alternative branch + ( start subpattern + ) end subpattern + ? extends the meaning of ( + also 0 or 1 quantifier + also quantifier minimizer + * 0 or more quantifier + + 1 or more quantifier + also "possessive quantifier" + { start min/max quantifier +.sp +Part of a pattern that is in square brackets is called a "character class". In +a character class the only metacharacters are: +.sp + \e general escape character + ^ negate the class, but only if the first character + - indicates character range +.\" JOIN + [ POSIX character class (only if followed by POSIX + syntax) + ] terminates the character class +.sp +The following sections describe the use of each of the metacharacters. +. +.SH BACKSLASH +.rs +.sp +The backslash character has several uses. Firstly, if it is followed by a +non-alphanumeric character, it takes away any special meaning that character +may have. This use of backslash as an escape character applies both inside and +outside character classes. +.P +For example, if you want to match a * character, you write \e* in the pattern. +This escaping action applies whether or not the following character would +otherwise be interpreted as a metacharacter, so it is always safe to precede a +non-alphanumeric with backslash to specify that it stands for itself. In +particular, if you want to match a backslash, you write \e\e. +.P +If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the +pattern (other than in a character class) and characters between a # outside +a character class and the next newline are ignored. An escaping backslash can +be used to include a whitespace or # character as part of the pattern. +.P +If you want to remove the special meaning from a sequence of characters, you +can do so by putting them between \eQ and \eE. This is different from Perl in +that $ and @ are handled as literals in \eQ...\eE sequences in PCRE, whereas in +Perl, $ and @ cause variable interpolation. Note the following examples: +.sp + Pattern PCRE matches Perl matches +.sp +.\" JOIN + \eQabc$xyz\eE abc$xyz abc followed by the + contents of $xyz + \eQabc\e$xyz\eE abc\e$xyz abc\e$xyz + \eQabc\eE\e$\eQxyz\eE abc$xyz abc$xyz +.sp +The \eQ...\eE sequence is recognized both inside and outside character classes. +. +. +.\" HTML <a name="digitsafterbackslash"></a> +.SS "Non-printing characters" +.rs +.sp +A second use of backslash provides a way of encoding non-printing characters +in patterns in a visible manner. There is no restriction on the appearance of +non-printing characters, apart from the binary zero that terminates a pattern, +but when a pattern is being prepared by text editing, it is usually easier to +use one of the following escape sequences than the binary character it +represents: +.sp + \ea alarm, that is, the BEL character (hex 07) + \ecx "control-x", where x is any character + \ee escape (hex 1B) + \ef formfeed (hex 0C) + \en newline (hex 0A) + \er carriage return (hex 0D) + \et tab (hex 09) + \eddd character with octal code ddd, or backreference + \exhh character with hex code hh + \ex{hhh..} character with hex code hhh.. +.sp +The precise effect of \ecx is as follows: if x is a lower case letter, it +is converted to upper case. Then bit 6 of the character (hex 40) is inverted. +Thus \ecz becomes hex 1A, but \ec{ becomes hex 3B, while \ec; becomes hex +7B. +.P +After \ex, from zero to two hexadecimal digits are read (letters can be in +upper or lower case). Any number of hexadecimal digits may appear between \ex{ +and }, but the value of the character code must be less than 256 in non-UTF-8 +mode, and less than 2**31 in UTF-8 mode (that is, the maximum hexadecimal value +is 7FFFFFFF). If characters other than hexadecimal digits appear between \ex{ +and }, or if there is no terminating }, this form of escape is not recognized. +Instead, the initial \ex will be interpreted as a basic hexadecimal escape, +with no following digits, giving a character whose value is zero. +.P +Characters whose value is less than 256 can be defined by either of the two +syntaxes for \ex. There is no difference in the way they are handled. For +example, \exdc is exactly the same as \ex{dc}. +.P +After \e0 up to two further octal digits are read. If there are fewer than two +digits, just those that are present are used. Thus the sequence \e0\ex\e07 +specifies two binary zeros followed by a BEL character (code value 7). Make +sure you supply two digits after the initial zero if the pattern character that +follows is itself an octal digit. +.P +The handling of a backslash followed by a digit other than 0 is complicated. +Outside a character class, PCRE reads it and any following digits as a decimal +number. If the number is less than 10, or if there have been at least that many +previous capturing left parentheses in the expression, the entire sequence is +taken as a \fIback reference\fP. A description of how this works is given +.\" HTML <a href="#backreferences"> +.\" </a> +later, +.\" +following the discussion of +.\" HTML <a href="#subpattern"> +.\" </a> +parenthesized subpatterns. +.\" +.P +Inside a character class, or if the decimal number is greater than 9 and there +have not been that many capturing subpatterns, PCRE re-reads up to three octal +digits following the backslash, ane uses them to generate a data character. Any +subsequent digits stand for themselves. In non-UTF-8 mode, the value of a +character specified in octal must be less than \e400. In UTF-8 mode, values up +to \e777 are permitted. For example: +.sp + \e040 is another way of writing a space +.\" JOIN + \e40 is the same, provided there are fewer than 40 + previous capturing subpatterns + \e7 is always a back reference +.\" JOIN + \e11 might be a back reference, or another way of + writing a tab + \e011 is always a tab + \e0113 is a tab followed by the character "3" +.\" JOIN + \e113 might be a back reference, otherwise the + character with octal code 113 +.\" JOIN + \e377 might be a back reference, otherwise + the byte consisting entirely of 1 bits +.\" JOIN + \e81 is either a back reference, or a binary zero + followed by the two characters "8" and "1" +.sp +Note that octal values of 100 or greater must not be introduced by a leading +zero, because no more than three octal digits are ever read. +.P +All the sequences that define a single character value can be used both inside +and outside character classes. In addition, inside a character class, the +sequence \eb is interpreted as the backspace character (hex 08), and the +sequence \eX is interpreted as the character "X". Outside a character class, +these sequences have different meanings +.\" HTML <a href="#uniextseq"> +.\" </a> +(see below). +.\" +. +. +.SS "Generic character types" +.rs +.sp +The third use of backslash is for specifying generic character types. The +following are always recognized: +.sp + \ed any decimal digit + \eD any character that is not a decimal digit + \es any whitespace character + \eS any character that is not a whitespace character + \ew any "word" character + \eW any "non-word" character +.sp +Each pair of escape sequences partitions the complete set of characters into +two disjoint sets. Any given character matches one, and only one, of each pair. +.P +These character type sequences can appear both inside and outside character +classes. They each match one character of the appropriate type. If the current +matching point is at the end of the subject string, all of them fail, since +there is no character to match. +.P +For compatibility with Perl, \es does not match the VT character (code 11). +This makes it different from the the POSIX "space" class. The \es characters +are HT (9), LF (10), FF (12), CR (13), and space (32). (If "use locale;" is +included in a Perl script, \es may match the VT character. In PCRE, it never +does.) +.P +A "word" character is an underscore or any character less than 256 that is a +letter or digit. The definition of letters and digits is controlled by PCRE's +low-valued character tables, and may vary if locale-specific matching is taking +place (see +.\" HTML <a href="pcreapi.html#localesupport"> +.\" </a> +"Locale support" +.\" +in the +.\" HREF +\fBpcreapi\fP +.\" +page). For example, in the "fr_FR" (French) locale, some character codes +greater than 128 are used for accented letters, and these are matched by \ew. +.P +In UTF-8 mode, characters with values greater than 128 never match \ed, \es, or +\ew, and always match \eD, \eS, and \eW.

Other properties such as "InMusicalSymbols" are +not currently supported by PCRE. Note that \eP{Any} does not match any +characters, so always causes a match failure. +.P +Sets of Unicode characters are defined as belonging to certain scripts. A +character from one of these sets can be matched using a script name.

For compatibility with Perl, negation can be specified +by including a circumflex between the opening brace and the property name. For +example, \ep{^Lu} is the same as \eP{Lu}. +.P +If only one letter is specified with \ep or \eP, it includes all the general +category properties that start with that letter. In this case, in the absence +of negation, the curly brackets in the escape sequence are optional; these two +examples have the same effect: +.sp + \ep{L} + \epL +.sp +The following general category property codes are supported: +.sp + C Other + Cc Control + Cf Format + Cn Unassigned + Co Private use + Cs Surrogate +.sp + L Letter + Ll Lower case letter + Lm Modifier letter + Lo Other letter + Lt Title case letter + Lu Upper case letter +.sp + M Mark + Mc Spacing mark + Me Enclosing mark + Mn Non-spacing mark +.sp + N Number + Nd Decimal number + Nl Letter number + No Other number +.sp + P Punctuation + Pc Connector punctuation + Pd Dash punctuation + Pe Close punctuation + Pf Final punctuation + Pi Initial punctuation + Po Other punctuation + Ps Open punctuation +.sp + S Symbol + Sc Currency symbol + Sk Modifier symbol + Sm Mathematical symbol + So Other symbol +.sp + Z Separator + Zl Line separator + Zp Paragraph separator + Zs Space separator +.sp +The special property L& is also supported: it matches a character that has +the Lu, Ll, or Lt property, in other words, a letter that is not classified as +a modifier or "other". +.P +The long synonyms for these properties that Perl supports (such as \ep{Letter}) +are not supported by PCRE, nor is it permitted to prefix any of these +properties with "Is". +.P +No character that is in the Unicode table has the Cn (unassigned) property. +Instead, this property is assumed for any code point that is not in the +Unicode table. +.P +Specifying caseless matching does not affect these escape sequences. For +example, \ep{Lu} always matches only upper case letters. +.P +The \eX escape matches any number of Unicode characters that form an extended +Unicode sequence. \eX is equivalent to +.sp + (?>\ePM\epM*) +.sp +That is, it matches a character without the "mark" property, followed by zero +or more characters with the "mark" property, and treats the sequence as an +atomic group +.\" HTML <a href="#atomicgroup"> +.\" </a> +(see below). +.\" +Characters with the "mark" property are typically accents that affect the +preceding character. +.P +Matching characters by Unicode property is not fast, because PCRE has to search +a structure that contains data for over fifteen thousand characters. That is +why the traditional escape sequences such as \ed and \ew do not use Unicode +properties in PCRE. +. +. +.\" HTML <a name="smallassertions"></a> +.SS "Simple assertions" +.rs +.sp +The fourth use of backslash is for certain simple assertions. An assertion +specifies a condition that has to be met at a particular point in a match, +without consuming any characters from the subject string. The use of +subpatterns for more complicated assertions is described +.\" HTML <a href="#bigassertions"> +.\" </a> +below. +.\" +The backslashed assertions are: +.sp + \eb matches at a word boundary + \eB matches when not at a word boundary + \eA matches at start of subject + \eZ matches at end of subject or before newline at end + \ez matches at end of subject + \eG matches at first matching position in subject +.sp +These assertions may not appear in character classes (but note that \eb has a +different meaning, namely the backspace character, inside a character class). +.P +A word boundary is a position in the subject string where the current character +and the previous character do not both match \ew or \eW (i.e. one matches +\ew and the other matches \eW), or the start or end of the string if the +first or last character matches \ew, respectively. +.P +The \eA, \eZ, and \ez assertions differ from the traditional circumflex and +dollar (described in the next section) in that they only ever match at the very +start and end of the subject string, whatever options are set. Thus, they are +independent of multiline mode. These three assertions are not affected by the +PCRE_NOTBOL or PCRE_NOTEOL options, which affect only the behaviour of the +circumflex and dollar metacharacters. However, if the \fIstartoffset\fP +argument of \fBpcre_exec()\fP is non-zero, indicating that matching is to start +at a point other than the beginning of the subject, \eA can never match. The +difference between \eZ and \ez is that \eZ matches before a newline at the end +of the string as well as at the very end, whereas \ez matches only at the end. +.P +The \eG assertion is true only when the current matching position is at the +start point of the match, as specified by the \fIstartoffset\fP argument of +\fBpcre_exec()\fP. It differs from \eA when the value of \fIstartoffset\fP is +non-zero. By calling \fBpcre_exec()\fP multiple times with appropriate +arguments, you can mimic Perl's /g option, and it is in this kind of +implementation where \eG can be useful. +.P +Note, however, that PCRE's interpretation of \eG, as the start of the current +match, is subtly different from Perl's, which defines it as the end of the +previous match. In Perl, these can be different when the previously matched +string was empty. Because PCRE does just one match at a time, it cannot +reproduce this behaviour. +.P +If all the alternatives of a pattern begin with \eG, the expression is anchored +to the starting match position, and the "anchored" flag is set in the compiled +regular expression. +. +. +.SH "CIRCUMFLEX AND DOLLAR" +.rs +.sp +Outside a character class, in the default matching mode, the circumflex +character is an assertion that is true only if the current matching point is +at the start of the subject string. If the \fIstartoffset\fP argument of +\fBpcre_exec()\fP is non-zero, circumflex can never match if the PCRE_MULTILINE +option is unset. Inside a character class, circumflex has an entirely different +meaning +.\" HTML <a href="#characterclass"> +.\" </a> +(see below). +.\" +.P +Circumflex need not be the first character of the pattern if a number of +alternatives are involved, but it should be the first thing in each alternative +in which it appears if the pattern is ever to match that branch. If all +possible alternatives start with a circumflex, that is, if the pattern is +constrained to match only at the start of the subject, it is said to be an +"anchored" pattern. (There are also other constructs that can cause a pattern +to be anchored.) +.P +A dollar character is an assertion that is true only if the current matching +point is at the end of the subject string, or immediately before a newline +at the end of the string (by default). Dollar need not be the last character of +the pattern if a number of alternatives are involved, but it should be the last +item in any branch in which it appears. Dollar has no special meaning in a +character class. +.P +The meaning of dollar can be changed so that it matches only at the very end of +the string, by setting the PCRE_DOLLAR_ENDONLY option at compile time. This +does not affect the \eZ assertion. +.P +The meanings of the circumflex and dollar characters are changed if the +PCRE_MULTILINE option is set. When this is the case, a circumflex matches +immediately after internal newlines as well as at the start of the subject +string. It does not match after a newline that ends the string. A dollar +matches before any newlines in the string, as well as at the very end, when +PCRE_MULTILINE is set. When newline is specified as the two-character +sequence CRLF, isolated CR and LF characters do not indicate newlines. +.P +For example, the pattern /^abc$/ matches the subject string "def\enabc" (where +\en represents a newline) in multiline mode, but not otherwise. Consequently, +patterns that are anchored in single line mode because all branches start with +^ are not anchored in multiline mode, and a match for circumflex is possible +when the \fIstartoffset\fP argument of \fBpcre_exec()\fP is non-zero. The +PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is set. +.P +Note that the sequences \eA, \eZ, and \ez can be used to match the start and +end of the subject in both modes, and if all branches of a pattern start with +\eA it is always anchored, whether or not PCRE_MULTILINE is set. +. +. +.SH "FULL STOP (PERIOD, DOT)" +.rs +.sp +Outside a character class, a dot in the pattern matches any one character in +the subject string except (by default) a character that signifies the end of a +line. In UTF-8 mode, the matched character may be more than one byte long. When +a line ending is defined as a single character (CR or LF), dot never matches +that character; when the two-character sequence CRLF is used, dot does not +match CR if it is immediately followed by LF, but otherwise it matches all +characters (including isolated CRs and LFs). +.P +The behaviour of dot with regard to newlines can be changed. If the PCRE_DOTALL +option is set, a dot matches any one character, without exception. If newline +is defined as the two-character sequence CRLF, it takes two dots to match it. +.P +The handling of dot is entirely independent of the handling of circumflex and +dollar, the only relationship being that they both involve newlines. Dot has no +special meaning in a character class. +. +. +.SH "MATCHING A SINGLE BYTE" +.rs +.sp +Outside a character class, the escape sequence \eC matches any one byte, both +in and out of UTF-8 mode. Unlike a dot, it always matches CR and LF. The +feature is provided in Perl in order to match individual bytes in UTF-8 mode. +Because it breaks up UTF-8 characters into individual bytes, what remains in +the string may be a malformed UTF-8 string. For this reason, the \eC escape +sequence is best avoided. +.P +PCRE does not allow \eC to appear in lookbehind assertions +.\" HTML <a href="#lookbehind"> +.\" </a> +(described below), +.\" +because in UTF-8 mode this would make it impossible to calculate the length of +the lookbehind. +. +. +.\" HTML <a name="characterclass"></a> +.SH "SQUARE BRACKETS AND CHARACTER CLASSES" +.rs +.sp +An opening square bracket introduces a character class, terminated by a closing +square bracket. A closing square bracket on its own is not special. If a +closing square bracket is required as a member of the class, it should be the +first data character in the class (after an initial circumflex, if present) or +escaped with a backslash. +.P +A character class matches a single character in the subject. In UTF-8 mode, the +character may occupy more than one byte. A matched character must be in the set +of characters defined by the class, unless the first character in the class +definition is a circumflex, in which case the subject character must not be in +the set defined by the class. If a circumflex is actually required as a member +of the class, ensure it is not the first character, or escape it with a +backslash. +.P +For example, the character class [aeiou] matches any lower case vowel, while +[^aeiou] matches any character that is not a lower case vowel. Note that a +circumflex is just a convenient notation for specifying the characters that +are in the class by enumerating those that are not. A class that starts with a +circumflex is not an assertion: it still consumes a character from the subject +string, and therefore it fails if the current pointer is at the end of the +string. +.P +In UTF-8 mode, characters with values greater than 255 can be included in a +class as a literal string of bytes, or by using the \ex{ escaping mechanism. +.P +When caseless matching is set, any letters in a class represent both their +upper case and lower case versions, so for example, a caseless [aeiou] matches +"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a +caseful version would. In UTF-8 mode, PCRE always understands the concept of +case for characters whose values are less than 128, so caseless matching is +always possible. For characters with higher values, the concept of case is +supported if PCRE is compiled with Unicode property support, but not otherwise. +If you want to use caseless matching for characters 128 and above, you must +ensure that PCRE is compiled with Unicode property support as well as with +UTF-8 support. +.P +Characters that might indicate line breaks (CR and LF) are never treated in any +special way when matching character classes, whatever line-ending sequence is +in use, and whatever setting of the PCRE_DOTALL and PCRE_MULTILINE options is +used. A class such as [^a] always matches one of these characters. +.P +The minus (hyphen) character can be used to specify a range of characters in a +character class. For example, [d-m] matches any letter between d and m, +inclusive. If a minus character is required in a class, it must be escaped with +a backslash or appear in a position where it cannot be interpreted as +indicating a range, typically as the first or last character in the class. +.P +It is not possible to have the literal character "]" as the end character of a +range. A pattern such as [W-]46] is interpreted as a class of two characters +("W" and "-") followed by a literal string "46]", so it would match "W46]" or +"-46]". However, if the "]" is escaped with a backslash it is interpreted as +the end of range, so [W-\e]46] is interpreted as a class containing a range +followed by two other characters. The octal or hexadecimal representation of +"]" can also be used to end a range. +.P +Ranges operate in the collating sequence of character values. They can also be +used for characters specified numerically, for example [\e000-\e037]. In UTF-8 +mode, ranges can include characters whose values are greater than 255, for +example [\ex{100}-\ex{2ff}]. +.P +If a range that includes letters is used when caseless matching is set, it +matches the letters in either case. For example, [W-c] is equivalent to +[][\e\e^_`wxyzabc], matched caselessly, and in non-UTF-8 mode, if character +tables for the "fr_FR" locale are in use, [\exc8-\excb] matches accented E +characters in both cases. In UTF-8 mode, PCRE supports the concept of case for +characters with values greater than 128 only when it is compiled with Unicode +property support. +.P +The character types \ed, \eD, \ep, \eP, \es, \eS, \ew, and \eW may also appear +in a character class, and add the characters that they match to the class. For +example, [\edABCDEF] matches any hexadecimal digit. A circumflex can +conveniently be used with the upper case character types to specify a more +restricted set of characters than the matching lower case type. For example, +the class [^\eW_] matches any letter or digit, but not underscore. +.P +The only metacharacters that are recognized in character classes are backslash, +hyphen (only where it can be interpreted as specifying a range), circumflex +(only at the start), opening square bracket (only when it can be interpreted as +introducing a POSIX class name - see the next section), and the terminating +closing square bracket. However, escaping other non-alphanumeric characters +does no harm. +. +. +.SH "POSIX CHARACTER CLASSES" +.rs +.sp +Perl supports the POSIX notation for character classes. This uses names +enclosed by [: and :] within the enclosing square brackets. PCRE also supports +this notation. For example, +.sp + [01[:alpha:]%] +.sp +matches "0", "1", any alphabetic character, or "%". The supported class names +are +.sp + alnum letters and digits + alpha letters + ascii character codes 0 - 127 + blank space or tab only + cntrl control characters + digit decimal digits (same as \ed) + graph printing characters, excluding space + lower lower case letters + print printing characters, including space + punct printing characters, excluding letters and digits + space white space (not quite the same as \es) + upper upper case letters + word "word" characters (same as \ew) + xdigit hexadecimal digits +.sp +The "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13), and +space (32). Notice that this list includes the VT character (code 11). This +makes "space" different to \es, which does not include VT (for Perl +compatibility). +.P +The name "word" is a Perl extension, and "blank" is a GNU extension from Perl +5.8. Another Perl extension is negation, which is indicated by a ^ character +after the colon. For example, +.sp + [12[:^digit:]] +.sp +matches "1", "2", or any non-digit. PCRE (and Perl) also recognize the POSIX +syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not +supported, and an error is given if they are encountered. +.P +In UTF-8 mode, characters with values greater than 128 do not match any of +the POSIX character classes. +. +. +.SH "VERTICAL BAR" +.rs +.sp +Vertical bar characters are used to separate alternative patterns. For example, +the pattern +.sp + gilbert|sullivan +.sp +matches either "gilbert" or "sullivan". Any number of alternatives may appear, +and an empty alternative is permitted (matching the empty string). The matching +process tries each alternative in turn, from left to right, and the first one +that succeeds is used. If the alternatives are within a subpattern +.\" HTML <a href="#subpattern"> +.\" </a> +(defined below), +.\" +"succeeds" means matching the rest of the main pattern as well as the +alternative in the subpattern. +. +. +.SH "INTERNAL OPTION SETTING" +.rs +.sp +The settings of the PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and +PCRE_EXTENDED options can be changed from within the pattern by a sequence of +Perl option letters enclosed between "(?" and ")". The option letters are +.sp + i for PCRE_CASELESS + m for PCRE_MULTILINE + s for PCRE_DOTALL + x for PCRE_EXTENDED +.sp +For example, (?im) sets caseless, multiline matching. It is also possible to +unset these options by preceding the letter with a hyphen, and a combined +setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and +PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also +permitted. If a letter appears both before and after the hyphen, the option is +unset. +.P +When an option change occurs at top level (that is, not inside subpattern +parentheses), the change applies to the remainder of the pattern that follows. +If the change is placed right at the start of a pattern, PCRE extracts it into +the global options (and it will therefore show up in data extracted by the +\fBpcre_fullinfo()\fP function). +.P +An option change within a subpattern affects only that part of the current +pattern that follows it, so +.sp + (a(?i)b)c +.sp +matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used). +By this means, options can be made to have different settings in different +parts of the pattern. Any changes made in one alternative do carry on +into subsequent branches within the same subpattern. For example, +.sp + (a(?i)b|c) +.sp +matches "ab", "aB", "c", and "C", even though when matching "C" the first +branch is abandoned before the option setting. This is because the effects of +option settings happen at compile time. There would be some very weird +behaviour otherwise. +.P +The PCRE-specific options PCRE_DUPNAMES, PCRE_UNGREEDY, and PCRE_EXTRA can be +changed in the same way as the Perl-compatible options by using the characters +J, U and X respectively. +. +. +.\" HTML <a name="subpattern"></a> +.SH SUBPATTERNS +.rs +.sp +Subpatterns are delimited by parentheses (round brackets), which can be nested. +Turning part of a pattern into a subpattern does two things: +.sp +1. It localizes a set of alternatives. For example, the pattern +.sp + cat(aract|erpillar|) +.sp +matches one of the words "cat", "cataract", or "caterpillar". Without the +parentheses, it would match "cataract", "erpillar" or the empty string. +.sp +2. It sets up the subpattern as a capturing subpattern. This means that, when +the whole pattern matches, that portion of the subject string that matched the +subpattern is passed back to the caller via the \fIovector\fP argument of +\fBpcre_exec()\fP. Opening parentheses are counted from left to right (starting +from 1) to obtain numbers for the capturing subpatterns. +.P +For example, if the string "the red king" is matched against the pattern +.sp + the ((red|white) (king|queen)) +.sp +the captured substrings are "red king", "red", and "king", and are numbered 1, +2, and 3, respectively. +.P +The fact that plain parentheses fulfil two functions is not always helpful. +There are often times when a grouping subpattern is required without a +capturing requirement. If an opening parenthesis is followed by a question mark +and a colon, the subpattern does not do any capturing, and is not counted when +computing the number of any subsequent capturing subpatterns. For example, if +the string "the white queen" is matched against the pattern +.sp + the ((?:red|white) (king|queen)) +.sp +the captured substrings are "white queen" and "queen", and are numbered 1 and +2. The maximum number of capturing subpatterns is 65535, and the maximum depth +of nesting of all subpatterns, both capturing and non-capturing, is 200. +.P +As a convenient shorthand, if any option settings are required at the start of +a non-capturing subpattern, the option letters may appear between the "?" and +the ":". Thus the two patterns +.sp + (?i:saturday|sunday) + (?:(?i)saturday|sunday) +.sp +match exactly the same set of strings. Because alternative branches are tried +from left to right, and options are not reset until the end of the subpattern +is reached, an option setting in one branch does affect subsequent branches, so +the above patterns match "SUNDAY" as well as "Saturday". +. +. +.SH "NAMED SUBPATTERNS" +.rs +.sp +Identifying capturing parentheses by number is simple, but it can be very hard +to keep track of the numbers in complicated regular expressions. Furthermore, +if an expression is modified, the numbers may change. To help with this +difficulty, PCRE supports the naming of subpatterns, something that Perl does +not provide. The Python syntax (?P<name>...) is used. References to capturing +parentheses from other parts of the pattern, such as +.\" HTML <a href="#backreferences"> +.\" </a> +backreferences, +.\" +.\" HTML <a href="#recursion"> +.\" </a> +recursion, +.\" +and +.\" HTML <a href="#conditions"> +.\" </a> +conditions, +.\" +can be made by name as well as by number. +.P +Names consist of up to 32 alphanumeric characters and underscores. Named +capturing parentheses are still allocated numbers as well as names. The PCRE +API provides function calls for extracting the name-to-number translation table +from a compiled pattern. There is also a convenience function for extracting a +captured substring by name. +.P +By default, a name must be unique within a pattern, but it is possible to relax +this constraint by setting the PCRE_DUPNAMES option at compile time. This can +be useful for patterns where only one instance of the named parentheses can +match. Suppose you want to match the name of a weekday, either as a 3-letter +abbreviation or as the full name, and in both cases you want to extract the +abbreviation. This pattern (ignoring the line breaks) does the job: +.sp + (?P<DN>Mon|Fri|Sun)(?:day)?| + (?P<DN>Tue)(?:sday)?| + (?P<DN>Wed)(?:nesday)?| + (?P<DN>Thu)(?:rsday)?| + (?P<DN>Sat)(?:urday)? +.sp +There are five capturing substrings, but only one is ever set after a match. +The convenience function for extracting the data by name returns the substring +for the first, and in this example, the only, subpattern of that name that +matched. This saves searching to find which numbered subpattern it was. If you +make a reference to a non-unique named subpattern from elsewhere in the +pattern, the one that corresponds to the lowest number is used. For further +details of the interfaces for handling named subpatterns, see the +.\" HREF +\fBpcreapi\fP +.\" +documentation. +. +. +.SH REPETITION +.rs +.sp +Repetition is specified by quantifiers, which can follow any of the following +items: +.sp + a literal data character + the . metacharacter + the \eC escape sequence + the \eX escape sequence (in UTF-8 mode with Unicode properties) + an escape such as \ed that matches a single character + a character class + a back reference (see next section) + a parenthesized subpattern (unless it is an assertion) +.sp +The general repetition quantifier specifies a minimum and maximum number of +permitted matches, by giving the two numbers in curly brackets (braces), +separated by a comma. The numbers must be less than 65536, and the first must +be less than or equal to the second. For example: +.sp + z{2,4} +.sp +matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special +character. If the second number is omitted, but the comma is present, there is +no upper limit; if the second number and the comma are both omitted, the +quantifier specifies an exact number of required matches. Thus +.sp + [aeiou]{3,} +.sp +matches at least 3 successive vowels, but may match many more, while +.sp + \ed{8} +.sp +matches exactly 8 digits. An opening curly bracket that appears in a position +where a quantifier is not allowed, or one that does not match the syntax of a +quantifier, is taken as a literal character. For example, {,6} is not a +quantifier, but a literal string of four characters. +.P +In UTF-8 mode, quantifiers apply to UTF-8 characters rather than to individual +bytes. Thus, for example, \ex{100}{2} matches two UTF-8 characters, each of +which is represented by a two-byte sequence. Similarly, when Unicode property +support is available, \eX{3} matches three Unicode extended sequences, each of +which may be several bytes long (and they may be of different lengths). +.P +The quantifier {0} is permitted, causing the expression to behave as if the +previous item and the quantifier were not present. +.P +For convenience (and historical compatibility) the three most common +quantifiers have single-character abbreviations: +.sp + * is equivalent to {0,} + + is equivalent to {1,} + ? is equivalent to {0,1} +.sp +It is possible to construct infinite loops by following a subpattern that can +match no characters with a quantifier that has no upper limit, for example: +.sp + (a?)* +.sp +Earlier versions of Perl and PCRE used to give an error at compile time for +such patterns. However, because there are cases where this can be useful, such +patterns are now accepted, but if any repetition of the subpattern does in fact +match no characters, the loop is forcibly broken. +.P +By default, the quantifiers are "greedy", that is, they match as much as +possible (up to the maximum number of permitted times), without causing the +rest of the pattern to fail. The classic example of where this gives problems +is in trying to match comments in C programs. These appear between /* and */ +and within the comment, individual * and / characters may appear. An attempt to +match C comments by applying the pattern +.sp + /\e*.*\e*/ +.sp +to the string +.sp + /* first comment */ not comment /* second comment */ +.sp +fails, because it matches the entire string owing to the greediness of the .* +item. +.P +However, if a quantifier is followed by a question mark, it ceases to be +greedy, and instead matches the minimum number of times possible, so the +pattern +.sp + /\e*.*?\e*/ +.sp +does the right thing with the C comments. The meaning of the various +quantifiers is not otherwise changed, just the preferred number of matches. +Do not confuse this use of question mark with its use as a quantifier in its +own right. Because it has two uses, it can sometimes appear doubled, as in +.sp + \ed??\ed +.sp +which matches one digit by preference, but can match two if that is the only +way the rest of the pattern matches. +.P +If the PCRE_UNGREEDY option is set (an option which is not available in Perl), +the quantifiers are not greedy by default, but individual ones can be made +greedy by following them with a question mark. In other words, it inverts the +default behaviour. +.P +When a parenthesized subpattern is quantified with a minimum repeat count that +is greater than 1 or with a limited maximum, more memory is required for the +compiled pattern, in proportion to the size of the minimum or maximum. +.P +If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent +to Perl's /s) is set, thus allowing the . to match newlines, the pattern is +implicitly anchored, because whatever follows will be tried against every +character position in the subject string, so there is no point in retrying the +overall match at any position after the first. PCRE normally treats such a +pattern as though it were preceded by \eA. +.P +In cases where it is known that the subject string contains no newlines, it is +worth setting PCRE_DOTALL in order to obtain this optimization, or +alternatively using ^ to indicate anchoring explicitly. +.P +However, there is one situation where the optimization cannot be used. When .* +is inside capturing parentheses that are the subject of a backreference +elsewhere in the pattern, a match at the start may fail, and a later one +succeed. Consider, for example: +.sp + (.*)abc\e1 +.sp +If the subject is "xyz123abc123" the match point is the fourth character. For +this reason, such a pattern is not implicitly anchored. +.P +When a capturing subpattern is repeated, the value captured is the substring +that matched the final iteration. For example, after +.sp + (tweedle[dume]{3}\es*)+ +.sp +has matched "tweedledum tweedledee" the value of the captured substring is +"tweedledee". However, if there are nested capturing subpatterns, the +corresponding captured values may have been set in previous iterations. For +example, after +.sp + /(a|(b))+/ +.sp +matches "aba" the value of the second captured substring is "b". +. +. +.\" HTML <a name="atomicgroup"></a> +.SH "ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS" +.rs +.sp +With both maximizing and minimizing repetition, failure of what follows +normally causes the repeated item to be re-evaluated to see if a different +number of repeats allows the rest of the pattern to match. Sometimes it is +useful to prevent this, either to change the nature of the match, or to cause +it fail earlier than it otherwise might, when the author of the pattern knows +there is no point in carrying on. +.P +Consider, for example, the pattern \ed+foo when applied to the subject line +.sp + 123456bar +.sp +After matching all 6 digits and then failing to match "foo", the normal +action of the matcher is to try again with only 5 digits matching the \ed+ +item, and then with 4, and so on, before ultimately failing. "Atomic grouping" +(a term taken from Jeffrey Friedl's book) provides the means for specifying +that once a subpattern has matched, it is not to be re-evaluated in this way. +.P +If we use atomic grouping for the previous example, the matcher would give up +immediately on failing to match "foo" the first time. The notation is a kind of +special parenthesis, starting with (?> as in this example: +.sp + (?>\ed+)foo +.sp +This kind of parenthesis "locks up" the part of the pattern it contains once +it has matched, and a failure further into the pattern is prevented from +backtracking into it. Backtracking past it to previous items, however, works as +normal. +.P +An alternative description is that a subpattern of this type matches the string +of characters that an identical standalone pattern would match, if anchored at +the current point in the subject string. +.P +Atomic grouping subpatterns are not capturing subpatterns. Simple cases such as +the above example can be thought of as a maximizing repeat that must swallow +everything it can. So, while both \ed+ and \ed+? are prepared to adjust the +number of digits they match in order to make the rest of the pattern match, +(?>\ed+) can only match an entire sequence of digits. +.P +Atomic groups in general can of course contain arbitrarily complicated +subpatterns, and can be nested. However, when the subpattern for an atomic +group is just a single repeated item, as in the example above, a simpler +notation, called a "possessive quantifier" can be used. This consists of an +additional + character following a quantifier. Using this notation, the +previous example can be rewritten as +.sp + \ed++foo +.sp +Possessive quantifiers are always greedy; the setting of the PCRE_UNGREEDY +option is ignored. They are a convenient notation for the simpler forms of +atomic group. However, there is no difference in the meaning or processing of a +possessive quantifier and the equivalent atomic group. +.P +The possessive quantifier syntax is an extension to the Perl syntax. Jeffrey +Friedl originated the idea (and the name) in the first edition of his book. +Mike McCloskey liked it, so implemented it when he built Sun's Java package, +and PCRE copied it from there. +.P +When a pattern contains an unlimited repeat inside a subpattern that can itself +be repeated an unlimited number of times, the use of an atomic group is the +only way to avoid some failing matches taking a very long time indeed. The +pattern +.sp + (\eD+|<\ed+>)*[!?] +.sp +matches an unlimited number of substrings that either consist of non-digits, or +digits enclosed in <>, followed by either ! or ?. When it matches, it runs +quickly. However, if it is applied to +.sp + aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +.sp +it takes a long time before reporting failure. This is because the string can +be divided between the internal \eD+ repeat and the external * repeat in a +large number of ways, and all have to be tried. (The example uses [!?] rather +than a single character at the end, because both PCRE and Perl have an +optimization that allows for fast failure when a single character is used. They +remember the last single character that is required for a match, and fail early +if it is not present in the string.) If the pattern is changed so that it uses +an atomic group, like this: +.sp + ((?>\eD+)|<\ed+>)*[!?] +.sp +sequences of non-digits cannot be broken, and failure happens quickly. +. +. +.\" HTML <a name="backreferences"></a> +.SH "BACK REFERENCES" +.rs +.sp +Outside a character class, a backslash followed by a digit greater than 0 (and +possibly further digits) is a back reference to a capturing subpattern earlier +(that is, to its left) in the pattern, provided there have been that many +previous capturing left parentheses. +.P +However, if the decimal number following the backslash is less than 10, it is +always taken as a back reference, and causes an error only if there are not +that many capturing left parentheses in the entire pattern. In other words, the +parentheses that are referenced need not be to the left of the reference for +numbers less than 10. A "forward back reference" of this type can make sense +when a repetition is involved and the subpattern to the right has participated +in an earlier iteration. +.P +It is not possible to have a numerical "forward back reference" to subpattern +whose number is 10 or more. However, a back reference to any subpattern is +possible using named parentheses (see below). See also the subsection entitled +"Non-printing characters" +.\" HTML <a href="#digitsafterbackslash"> +.\" </a> +above +.\" +for further details of the handling of digits following a backslash. +.P +A back reference matches whatever actually matched the capturing subpattern in +the current subject string, rather than anything matching the subpattern +itself (see +.\" HTML <a href="#subpatternsassubroutines"> +.\" </a> +"Subpatterns as subroutines" +.\" +below for a way of doing that). So the pattern +.sp + (sens|respons)e and \e1ibility +.sp +matches "sense and sensibility" and "response and responsibility", but not +"sense and responsibility". If caseful matching is in force at the time of the +back reference, the case of letters is relevant. For example, +.sp + ((?i)rah)\es+\e1 +.sp +matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original +capturing subpattern is matched caselessly. +.P +Back references to named subpatterns use the Python syntax (?P=name). We could +rewrite the above example as follows: +.sp + (?P<p1>(?i)rah)\es+(?P=p1) +.sp +A subpattern that is referenced by name may appear in the pattern before or +after the reference. +.P +There may be more than one back reference to the same subpattern. If a +subpattern has not actually been used in a particular match, any back +references to it always fail. For example, the pattern +.sp + (a|(bc))\e2 +.sp +always fails if it starts to match "a" rather than "bc". Because there may be +many capturing parentheses in a pattern, all digits following the backslash are +taken as part of a potential back reference number. If the pattern continues +with a digit character, some delimiter must be used to terminate the back +reference. If the PCRE_EXTENDED option is set, this can be whitespace. +Otherwise an empty comment (see +.\" HTML <a href="#comments"> +.\" </a> +"Comments" +.\" +below) can be used. +.P +A back reference that occurs inside the parentheses to which it refers fails +when the subpattern is first used, so, for example, (a\e1) never matches. +However, such references can be useful inside repeated subpatterns. For +example, the pattern +.sp + (a|b\e1)+ +.sp +matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of +the subpattern, the back reference matches the character string corresponding +to the previous iteration. In order for this to work, the pattern must be such +that the first iteration does not need to match the back reference. This can be +done using alternation, as in the example above, or by a quantifier with a +minimum of zero. +. +. +.\" HTML <a name="bigassertions"></a> +.SH ASSERTIONS +.rs +.sp +An assertion is a test on the characters following or preceding the current +matching point that does not actually consume any characters. The simple +assertions coded as \eb, \eB, \eA, \eG, \eZ, \ez, ^ and $ are described +.\" HTML <a href="#smallassertions"> +.\" </a> +above. +.\" +.P +More complicated assertions are coded as subpatterns. There are two kinds: +those that look ahead of the current position in the subject string, and those +that look behind it. An assertion subpattern is matched in the normal way, +except that it does not cause the current matching position to be changed. +.P +Assertion subpatterns are not capturing subpatterns, and may not be repeated, +because it makes no sense to assert the same thing several times. If any kind +of assertion contains capturing subpatterns within it, these are counted for +the purposes of numbering the capturing subpatterns in the whole pattern. +However, substring capturing is carried out only for positive assertions, +because it does not make sense for negative assertions. +. +. +.SS "Lookahead assertions" +.rs +.sp +Lookahead assertions start with (?= for positive assertions and (?! for +negative assertions. For example, +.sp + \ew+(?=;) +.sp +matches a word followed by a semicolon, but does not include the semicolon in +the match, and +.sp + foo(?!bar) +.sp +matches any occurrence of "foo" that is not followed by "bar". Note that the +apparently similar pattern +.sp + (?!foo)bar +.sp +does not find an occurrence of "bar" that is preceded by something other than +"foo"; it finds any occurrence of "bar" whatsoever, because the assertion +(?!foo) is always true when the next three characters are "bar". A +lookbehind assertion is needed to achieve the other effect. +.P +If you want to force a matching failure at some point in a pattern, the most +convenient way to do it is with (?!) because an empty string always matches, so +an assertion that requires there not to be an empty string must always fail. +. +. +.\" HTML <a name="lookbehind"></a> +.SS "Lookbehind assertions" +.rs +.sp +Lookbehind assertions start with (?<= for positive assertions and (?<! for +negative assertions. For example, +.sp + (?<!foo)bar +.sp +does find an occurrence of "bar" that is not preceded by "foo". The contents of +a lookbehind assertion are restricted such that all the strings it matches must +have a fixed length. However, if there are several top-level alternatives, they +do not all have to have the same fixed length. Thus +.sp + (?<=bullock|donkey) +.sp +is permitted, but +.sp + (?<!dogs?|cats?) +.sp +causes an error at compile time. Branches that match different length strings +are permitted only at the top level of a lookbehind assertion. This is an +extension compared with Perl (at least for 5.8), which requires all branches to +match the same length of string. An assertion such as +.sp + (?<=ab(c|de)) +.sp +is not permitted, because its single top-level branch can match two different +lengths, but it is acceptable if rewritten to use two top-level branches: +.sp + (?<=abc|abde) +.sp +The implementation of lookbehind assertions is, for each alternative, to +temporarily move the current position back by the fixed width and then try to +match. If there are insufficient characters before the current position, the +match is deemed to fail. +.P +PCRE does not allow the \eC escape (which matches a single byte in UTF-8 mode) +to appear in lookbehind assertions, because it makes it impossible to calculate +the length of the lookbehind. The \eX escape, which can match different numbers +of bytes, is also not permitted. +.P +Atomic groups can be used in conjunction with lookbehind assertions to specify +efficient matching at the end of the subject string. Consider a simple pattern +such as +.sp + abcd$ +.sp +when applied to a long string that does not match. Because matching proceeds +from left to right, PCRE will look for each "a" in the subject and then see if +what follows matches the rest of the pattern. If the pattern is specified as +.sp + ^.*abcd$ +.sp +the initial .* matches the entire string at first, but when this fails (because +there is no following "a"), it backtracks to match all but the last character, +then all but the last two characters, and so on. Once again the search for "a" +covers the entire string, from right to left, so we are no better off. However, +if the pattern is written as +.sp + ^(?>.*)(?<=abcd) +.sp +or, equivalently, using the possessive quantifier syntax, +.sp + ^.*+(?<=abcd) +.sp +there can be no backtracking for the .* item; it can match only the entire +string. The subsequent lookbehind assertion does a single test on the last four +characters. If it fails, the match fails immediately. For long strings, this +approach makes a significant difference to the processing time. +. +. +.SS "Using multiple assertions" +.rs +.sp +Several assertions (of any sort) may occur in succession. For example, +.sp + (?<=\ed{3})(?<!999)foo +.sp +matches "foo" preceded by three digits that are not "999". Notice that each of +the assertions is applied independently at the same point in the subject +string. First there is a check that the previous three characters are all +digits, and then there is a check that the same three characters are not "999". +This pattern does \fInot\fP match "foo" preceded by six characters, the first +of which are digits and the last three of which are not "999". For example, it +doesn't match "123abcfoo". A pattern to do that is +.sp + (?<=\ed{3}...)(?<!999)foo +.sp +This time the first assertion looks at the preceding six characters, checking +that the first three are digits, and then the second assertion checks that the +preceding three characters are not "999". +.P +Assertions can be nested in any combination. For example, +.sp + (?<=(?<!foo)bar)baz +.sp +matches an occurrence of "baz" that is preceded by "bar" which in turn is not +preceded by "foo", while +.sp + (?<=\ed{3}(?!999)...)foo +.sp +is another pattern that matches "foo" preceded by three digits and any three +characters that are not "999". +. +. +.\" HTML <a name="conditions"></a> +.SH "CONDITIONAL SUBPATTERNS" +.rs +.sp +It is possible to cause the matching process to obey a subpattern +conditionally or to choose between two alternative subpatterns, depending on +the result of an assertion, or whether a previous capturing subpattern matched +or not. The two possible forms of conditional subpattern are +.sp + (?(condition)yes-pattern) + (?(condition)yes-pattern|no-pattern) +.sp +If the condition is satisfied, the yes-pattern is used; otherwise the +no-pattern (if present) is used. If there are more than two alternatives in the +subpattern, a compile-time error occurs. +.P +There are three kinds of condition. If the text between the parentheses +consists of a sequence of digits, or a sequence of alphanumeric characters and +underscores, the condition is satisfied if the capturing subpattern of that +number or name has previously matched. There is a possible ambiguity here, +because subpattern names may consist entirely of digits. PCRE looks first for a +named subpattern; if it cannot find one and the text consists entirely of +digits, it looks for a subpattern of that number, which must be greater than +zero. Using subpattern names that consist entirely of digits is not +recommended. +.P +Consider the following pattern, which contains non-significant white space to +make it more readable (assume the PCRE_EXTENDED option) and to divide it into +three parts for ease of discussion: +.sp + ( \e( )? [^()]+ (?(1) \e) ) +.sp +The first part matches an optional opening parenthesis, and if that +character is present, sets it as the first captured substring. The second part +matches one or more characters that are not parentheses. The third part is a +conditional subpattern that tests whether the first set of parentheses matched +or not. If they did, that is, if subject started with an opening parenthesis, +the condition is true, and so the yes-pattern is executed and a closing +parenthesis is required. Otherwise, since no-pattern is not present, the +subpattern matches nothing. In other words, this pattern matches a sequence of +non-parentheses, optionally enclosed in parentheses. Rewriting it to use a +named subpattern gives this: +.sp + (?P<OPEN> \e( )? [^()]+ (?(OPEN) \e) ) +.sp +If the condition is the string (R), and there is no subpattern with the name R, +the condition is satisfied if a recursive call to the pattern or subpattern has +been made. At "top level", the condition is false. This is a PCRE extension. +Recursive patterns are described in the next section. +.P +If the condition is not a sequence of digits or (R), it must be an assertion. +This may be a positive or negative lookahead or lookbehind assertion. Consider +this pattern, again containing non-significant white space, and with the two +alternatives on the second line: +.sp + (?(?=[^a-z]*[a-z]) + \ed{2}-[a-z]{3}-\ed{2} | \ed{2}-\ed{2}-\ed{2} ) +.sp +The condition is a positive lookahead assertion that matches an optional +sequence of non-letters followed by a letter. In other words, it tests for the +presence of at least one letter in the subject. If a letter is found, the +subject is matched against the first alternative; otherwise it is matched +against the second. This pattern matches strings in one of the two forms +dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits. +. +. +.\" HTML <a name="comments"></a> +.SH COMMENTS +.rs +.sp +The sequence (?# marks the start of a comment that continues up to the next +closing parenthesis. Nested parentheses are not permitted. The characters +that make up a comment play no part in the pattern matching at all. +.P +If the PCRE_EXTENDED option is set, an unescaped # character outside a +character class introduces a comment that continues to immediately after the +next newline in the pattern. +. +. +.\" HTML <a name="recursion"></a> +.SH "RECURSIVE PATTERNS" +.rs +.sp +Consider the problem of matching a string in parentheses, allowing for +unlimited nested parentheses. Without the use of recursion, the best that can +be done is to use a pattern that matches up to some fixed depth of nesting. It +is not possible to handle an arbitrary nesting depth. Perl provides a facility +that allows regular expressions to recurse (amongst other things). It does this +by interpolating Perl code in the expression at run time, and the code can +refer to the expression itself. A Perl pattern to solve the parentheses problem +can be created like this: +.sp + $re = qr{\e( (?: (?>[^()]+) | (?p{$re}) )* \e)}x; +.sp +The (?p{...}) item interpolates Perl code at run time, and in this case refers +recursively to the pattern in which it appears. Obviously, PCRE cannot support +the interpolation of Perl code. Instead, it supports some special syntax for +recursion of the entire pattern, and also for individual subpattern recursion. +.P +The special item that consists of (? followed by a number greater than zero and +a closing parenthesis is a recursive call of the subpattern of the given +number, provided that it occurs inside that subpattern. (If not, it is a +"subroutine" call, which is described in the next section.) The special item +(?R) is a recursive call of the entire regular expression. +.P +A recursive subpattern call is always treated as an atomic group. That is, once +it has matched some of the subject string, it is never re-entered, even if +it contains untried alternatives and there is a subsequent matching failure. +.P +This PCRE pattern solves the nested parentheses problem (assume the +PCRE_EXTENDED option is set so that white space is ignored): +.sp + \e( ( (?>[^()]+) | (?R) )* \e) +.sp +First it matches an opening parenthesis. Then it matches any number of +substrings which can either be a sequence of non-parentheses, or a recursive +match of the pattern itself (that is, a correctly parenthesized substring). +Finally there is a closing parenthesis. +.P +If this were part of a larger pattern, you would not want to recurse the entire +pattern, so instead you could use this: +.sp + ( \e( ( (?>[^()]+) | (?1) )* \e) ) +.sp +We have put the pattern into parentheses, and caused the recursion to refer to +them instead of the whole pattern. In a larger pattern, keeping track of +parenthesis numbers can be tricky. It may be more convenient to use named +parentheses instead. For this, PCRE uses (?P>name), which is an extension to +the Python syntax that PCRE uses for named parentheses (Perl does not provide +named parentheses). We could rewrite the above example as follows: +.sp + (?P<pn> \e( ( (?>[^()]+) | (?P>pn) )* \e) ) +.sp +This particular example pattern contains nested unlimited repeats, and so the +use of atomic grouping for matching strings of non-parentheses is important +when applying the pattern to strings that do not match. For example, when this +pattern is applied to +.sp + (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa() +.sp +it yields "no match" quickly. However, if atomic grouping is not used, +the match runs for a very long time indeed because there are so many different +ways the + and * repeats can carve up the subject, and all have to be tested +before failure can be reported. +.P +At the end of a match, the values set for any capturing subpatterns are those +from the outermost level of the recursion at which the subpattern value is set. +If you want to obtain intermediate values, a callout function can be used (see +the next section and the +.\" HREF +\fBpcrecallout\fP +.\" +documentation). If the pattern above is matched against +.sp + (ab(cd)ef) +.sp +the value for the capturing parentheses is "ef", which is the last value taken +on at the top level. If additional parentheses are added, giving +.sp + \e( ( ( (?>[^()]+) | (?R) )* ) \e) + ^ ^ + ^ ^ +.sp +the string they capture is "ab(cd)ef", the contents of the top level +parentheses. If there are more than 15 capturing parentheses in a pattern, PCRE +has to obtain extra memory to store data during a recursion, which it does by +using \fBpcre_malloc\fP, freeing it via \fBpcre_free\fP afterwards. If no +memory can be obtained, the match fails with the PCRE_ERROR_NOMEMORY error. +.P +Do not confuse the (?R) item with the condition (R), which tests for recursion. +Consider this pattern, which matches text in angle brackets, allowing for +arbitrary nesting. Only digits are allowed in nested brackets (that is, when +recursing), whereas any characters are permitted at the outer level. +.sp + < (?: (?(R) \ed++ | [^<>]*+) | (?R)) * > +.sp +In this pattern, (?(R) is the start of a conditional subpattern, with two +different alternatives for the recursive and non-recursive cases. The (?R) item +is the actual recursive call. +. +. +.\" HTML <a name="subpatternsassubroutines"></a> +.SH "SUBPATTERNS AS SUBROUTINES" +.rs +.sp +If the syntax for a recursive subpattern reference (either by number or by +name) is used outside the parentheses to which it refers, it operates like a +subroutine in a programming language. An earlier example pointed out that the +pattern +.sp + (sens|respons)e and \e1ibility +.sp +matches "sense and sensibility" and "response and responsibility", but not +"sense and responsibility". If instead the pattern +.sp + (sens|respons)e and (?1)ibility +.sp +is used, it does match "sense and responsibility" as well as the other two +strings. Such references, if given numerically, must follow the subpattern to +which they refer. However, named references can refer to later subpatterns. +.P +Like recursive subpatterns, a "subroutine" call is always treated as an atomic +group. That is, once it has matched some of the subject string, it is never +re-entered, even if it contains untried alternatives and there is a subsequent +matching failure. +. +. +.SH CALLOUTS +.rs +.sp +Perl has a feature whereby using the sequence (?{...}) causes arbitrary Perl +code to be obeyed in the middle of matching a regular expression. This makes it +possible, amongst other things, to extract different substrings that match the +same pair of parentheses when there is a repetition. +.P +PCRE provides a similar feature, but of course it cannot obey arbitrary Perl +code. The feature is called "callout". The caller of PCRE provides an external +function by putting its entry point in the global variable \fIpcre_callout\fP. +By default, this variable contains NULL, which disables all calling out. +.P +Within a regular expression, (?C) indicates the points at which the external +function is to be called. If you want to identify different callout points, you +can put a number less than 256 after the letter C. The default value is zero. +For example, this pattern has two callout points: +.sp + (?C1)\dabc(?C2)def +.sp +If the PCRE_AUTO_CALLOUT flag is passed to \fBpcre_compile()\fP, callouts are +automatically installed before each item in the pattern. They are all numbered +255. +.P +During matching, when PCRE reaches a callout point (and \fIpcre_callout\fP is +set), the external function is called. It is provided with the number of the +callout, the position in the pattern, and, optionally, one item of data +originally supplied by the caller of \fBpcre_exec()\fP.

It is more efficient to use a character class like [aeiou] than a +set of alternatives such as (a|e|i|o|u). In general, the simplest construction +that provides the required behaviour is usually the most efficient. Jeffrey +Friedl's book contains a lot of useful general discussion about optimizing +regular expressions for efficient performance. This document contains a few +observations about PCRE. +.P +Using Unicode character properties (the \ep, \eP, and \eX escapes) is slow, +because PCRE has to scan a structure that contains data for over fifteen +thousand characters whenever it needs a character's property. If you can find +an alternative pattern that does not use character properties, it will probably +be faster. +.P +When a pattern begins with .* not in parentheses, or in parentheses that are +not the subject of a backreference, and the PCRE_DOTALL option is set, the +pattern is implicitly anchored by PCRE, since it can match only at the start of +a subject string. However, if PCRE_DOTALL is not set, PCRE cannot make this +optimization, because the . metacharacter does not then match a newline, and if +the subject string contains newlines, the pattern may match from the character +immediately following one of them instead of from the very start. For example, +the pattern +.sp + .*second +.sp +matches the subject "first\enand second" (where \en stands for a newline +character), with the match starting at the seventh character. In order to do +this, PCRE has to retry the match starting after every newline in the subject. +.P +If you are using such a pattern with subject strings that do not contain +newlines, the best performance is obtained by setting PCRE_DOTALL, or starting +the pattern with ^.* or ^.*? to indicate explicit anchoring. That saves PCRE +from having to scan along the subject looking for a newline to restart at. +.P +Beware of patterns that contain nested indefinite repeats. These can take a +long time to run when applied to a string that does not match. Consider the +pattern fragment +.sp + (a+)* +.sp +This can match "aaaa" in 33 different ways, and this number increases very +rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4 +times, and for each of those cases other than 0, the + repeats can match +different numbers of times.) When the remainder of the pattern is such that the +entire match is going to fail, PCRE has in principle to try every possible +variation, and this can take an extremely long time. +.P +An optimization catches some of the more simple cases such as +.sp + (a+)*b +.sp +where a literal character follows. Before embarking on the standard matching +procedure, PCRE checks that there is a "b" later in the subject string, and if +there is not, it fails the match immediately. However, when there is no +following literal this optimization cannot be used. You can see the difference +by comparing the behaviour of +.sp + (a+)*\ed +.sp +with the pattern above. The former gives a failure almost instantly when +applied to a whole line of "a" characters, whereas the latter takes an +appreciable time with strings longer than about 20 characters. +.P +In many cases, the solution to this kind of performance issue is to use an +atomic group or a possessive quantifier. +.P +.in 0 +Last updated: 28 February 2005 +.br +Copyright (c) 1997-2005 University of Cambridge.

In addition, the option REG_EXTENDED is defined with the value +zero. This has no effect, but since programs that are written to the POSIX +interface often use it, this makes it easier to slot in PCRE as a replacement +library. Other POSIX options are not even defined. +.P +When PCRE is called via these functions, it is only the API that is POSIX-like +in style. The syntax and semantics of the regular expressions themselves are +still those of Perl, subject to the setting of various PCRE options, as +described below. "POSIX-like in style" means that the API approximates to the +POSIX definition; it is not fully POSIX-compatible, and in multi-byte encoding +domains it is probably even less compatible. +.P +The header for these functions is supplied as \fBpcreposix.h\fP to avoid any +potential clash with other POSIX libraries. It can, of course, be renamed or +aliased as \fBregex.h\fP, which is the "correct" name. It provides two +structure types, \fIregex_t\fP for compiled internal forms, and +\fIregmatch_t\fP for returning captured substrings. It also defines some +constants whose names start with "REG_"; these are used for setting options and +identifying error codes. +.P +.SH "COMPILING A PATTERN" +.rs +.sp +The function \fBregcomp()\fP is called to compile a pattern into an +internal form. The pattern is a C string terminated by a binary zero, and +is passed in the argument \fIpattern\fP. The \fIpreg\fP argument is a pointer +to a \fBregex_t\fP structure that is used as a base for storing information +about the compiled regular expression. +.P +The argument \fIcflags\fP is either zero, or contains one or more of the bits +defined by the following macros: +.sp + REG_DOTALL +.sp +The PCRE_DOTALL option is set when the regular expression is passed for +compilation to the native function. Note that REG_DOTALL is not part of the +POSIX standard. +.sp + REG_ICASE +.sp +The PCRE_CASELESS option is set when the regular expression is passed for +compilation to the native function. +.sp + REG_NEWLINE +.sp +The PCRE_MULTILINE option is set when the regular expression is passed for +compilation to the native function. Note that this does \fInot\fP mimic the +defined POSIX behaviour for REG_NEWLINE (see the following section). +.sp + REG_NOSUB +.sp +The PCRE_NO_AUTO_CAPTURE option is set when the regular expression is passed +for compilation to the native function. In addition, when a pattern that is +compiled with this flag is passed to \fBregexec()\fP for matching, the +\fInmatch\fP and \fIpmatch\fP arguments are ignored, and no captured strings +are returned. +.sp + REG_UTF8 +.sp +The PCRE_UTF8 option is set when the regular expression is passed for +compilation to the native function. This causes the pattern itself and all data +strings used for matching it to be treated as UTF-8 strings. Note that REG_UTF8 +is not part of the POSIX standard. +.P +In the absence of these flags, no options are passed to the native function. +This means the the regex is compiled with PCRE default semantics. In +particular, the way it handles newline characters in the subject string is the +Perl way, not the POSIX way. Note that setting PCRE_MULTILINE has only +\fIsome\fP of the effects specified for REG_NEWLINE. It does not affect the way +newlines are matched by . (they aren't) or by a negative class such as [^a] +(they are). +.P +The yield of \fBregcomp()\fP is zero on success, and non-zero otherwise. The +\fIpreg\fP structure is filled in on success, and one member of the structure +is public: \fIre_nsub\fP contains the number of capturing subpatterns in +the regular expression. Various error codes are defined in the header file. +. +. +.SH "MATCHING NEWLINE CHARACTERS" +.rs +.sp +This area is not simple, because POSIX and Perl take different views of things. +It is not possible to get PCRE to obey POSIX semantics, but then PCRE was never +intended to be a POSIX engine. The following table lists the different +possibilities for matching newline characters in PCRE: +.sp + Default Change with +.sp + . matches newline no PCRE_DOTALL + newline matches [^a] yes not changeable + $ matches \en at end yes PCRE_DOLLARENDONLY + $ matches \en in middle no PCRE_MULTILINE + ^ matches \en in middle no PCRE_MULTILINE +.sp +This is the equivalent table for POSIX: +.sp + Default Change with +.sp + . matches newline yes REG_NEWLINE + newline matches [^a] yes REG_NEWLINE + $ matches \en at end no REG_NEWLINE + $ matches \en in middle no REG_NEWLINE + ^ matches \en in middle no REG_NEWLINE +.sp +PCRE's behaviour is the same as Perl's, except that there is no equivalent for +PCRE_DOLLAR_ENDONLY in Perl. In both PCRE and Perl, there is no way to stop +newline from matching [^a]. +.P +The default POSIX newline handling can be obtained by setting PCRE_DOTALL and +PCRE_DOLLAR_ENDONLY, but there is no way to make PCRE behave exactly as for the +REG_NEWLINE action. +. +. +.SH "MATCHING A PATTERN" +.rs +.sp +The function \fBregexec()\fP is called to match a compiled pattern \fIpreg\fP +against a given \fIstring\fP, which is terminated by a zero byte, subject to +the options in \fIeflags\fP. These can be: +.sp + REG_NOTBOL +.sp +The PCRE_NOTBOL option is set when calling the underlying PCRE matching +function. +.sp + REG_NOTEOL +.sp +The PCRE_NOTEOL option is set when calling the underlying PCRE matching +function. +.P +If the pattern was compiled with the REG_NOSUB flag, no data about any matched +strings is returned. The \fInmatch\fP and \fIpmatch\fP arguments of +\fBregexec()\fP are ignored. +.P +Otherwise,the portion of the string that was matched, and also any captured +substrings, are returned via the \fIpmatch\fP argument, which points to an +array of \fInmatch\fP structures of type \fIregmatch_t\fP, containing the +members \fIrm_so\fP and \fIrm_eo\fP. These contain the offset to the first +character of each substring and the offset to the first character after the end +of each substring, respectively. The 0th element of the vector relates to the +entire portion of \fIstring\fP that was matched; subsequent elements relate to +the capturing subpatterns of the regular expression. Unused entries in the +array have both structure members set to -1. +.P +A successful match yields a zero return; various error codes are defined in the +header file, of which REG_NOMATCH is the "expected" failure code. +. +. +.SH "ERROR MESSAGES" +.rs +.sp +The \fBregerror()\fP function maps a non-zero errorcode from either +\fBregcomp()\fP or \fBregexec()\fP to a printable message. If \fIpreg\fP is not +NULL, the error should have arisen from the use of that structure. A message +terminated by a binary zero is placed in \fIerrbuf\fP. The length of the +message, including the zero, is limited to \fIerrbuf_size\fP. The yield of the +function is the size of buffer needed to hold the whole message. +. +. +.SH MEMORY USAGE +.rs +.sp +Compiling a regular expression causes memory to be allocated and associated +with the \fIpreg\fP structure.

If you are using private +tables, it is a little bit more complicated. +.P +If you save compiled patterns to a file, you can copy them to a different host +and run them there.

Note that this is binary data that may contain any of the 256 possible +byte values. On systems that make a distinction between binary and non-binary +data, be sure that the file is opened for binary output. +.P +If you want to write more than one pattern to a file, you will have to devise a +way of separating them. For binary data, preceding each pattern with its length +is probably the most straightforward approach. Another possibility is to write +out the data in hexadecimal instead of binary, one pattern to a line. +.P +Saving compiled patterns in a file is only one possible way of storing them for +later use. They could equally well be saved in a database, or in the memory of +some daemon process that passes them via sockets to the processes that want +them. +.P +If the pattern has been studied, it is also possible to save the study data in +a similar way to the compiled pattern itself.

As matching proceeds deeper and +deeper into the tree of possibilities, the recursion depth increases. +.P +Not all calls of \fBmatch()\fP increase the recursion depth; for an item such +as a* it may be called several times at the same level, after matching +different numbers of a's. Furthermore, in a number of cases where the result of +the recursive call would immediately be passed back as the result of the +current call (a "tail recursion"), the function is just restarted instead. +.P +The \fBpcre_dfa_exec()\fP function operates in an entirely different way, and +hardly uses recursion at all. The limit on its complexity is the amount of +workspace it is given. The comments that follow do NOT apply to +\fBpcre_dfa_exec()\fP; they are relevant only for \fBpcre_exec()\fP. +.P +You can set limits on the number of times that \fBmatch()\fP is called, both in +total and recursively.

For certain kinds of pattern and data, very large +amounts of stack may be needed, despite the recognition of "tail recursion". +You can often reduce the amount of recursion, and therefore the amount of stack +used, by modifying the pattern that is being matched. Consider, for example, +this pattern: +.sp + ([^<]|<(?!inet))+ +.sp +It matches from wherever it starts until it encounters "<inet" or the end of +the data, and is the kind of pattern that might be used when processing an XML +file. Each iteration of the outer parentheses matches either one character that +is not "<" or a "<" that is not followed by "inet". However, each time a +parenthesis is processed, a recursion occurs, so this formulation uses a stack +frame for each matched character. For a long string, a lot of stack is +required. Consider now this rewritten pattern, which matches exactly the same +strings: +.sp + ([^<]++|<(?!inet)) +.sp +This uses very much less stack, because runs of characters that do not contain +"<" are "swallowed" in one item inside the parentheses. Recursion happens only +when a "<" character that is not followed by "inet" is encountered (and we +assume this is relatively rare). A possessive quantifier is used to stop any +backtracking into the runs of non-"<" characters, but that is not related to +stack usage. +.P +In environments where stack memory is constrained, you might want to compile +PCRE to use heap memory instead of stack for remembering back-up points. This +makes it run a lot more slowly, however. Details of how to do this are given in +the +.\" HREF +\fBpcrebuild\fP +.\" +documentation. +.P +In Unix-like environments, there is not often a problem with the stack, though +the default limit on stack size varies from system to system. Values from 8Mb +to 64Mb are common. You can find your default limit by running the command: +.sp + ulimit -s +.sp +The effect of running out of stack is often SIGSEGV, though sometimes an error +message is given. You can normally increase the limit on stack size by code +such as this: +.sp + struct rlimit rlim; + getrlimit(RLIMIT_STACK, &rlim); + rlim.rlim_cur = 100*1024*1024; + setrlimit(RLIMIT_STACK, &rlim); +.sp +This reads the current limits (soft and hard) using \fBgetrlimit()\fP, then +attempts to increase the soft limit to 100Mb using \fBsetrlimit()\fP. You must +do this before calling \fBpcre_exec()\fP. +.P +PCRE has an internal counter that can be used to limit the depth of recursion, +and thus cause \fBpcre_exec()\fP to give an error code before it runs out of +stack. By default, the limit is very large, and unlikely ever to operate. It +can be changed when PCRE is built, and it can also be set when +\fBpcre_exec()\fP is called. For details of these interfaces, see the +.\" HREF +\fBpcrebuild\fP +.\" +and +.\" HREF +\fBpcreapi\fP +.\" +documentation. +.P +As a very rough rule of thumb, you should reckon on about 500 bytes per +recursion.

Do not set \fB-m\fP with +\fB-t\fP, because you will then get the size output a zillion times, and the +timing will be distorted. +. +. +.SH DESCRIPTION +.rs +.sp +If \fBpcretest\fP is given two filename arguments, it reads from the first and +writes to the second. If it is given only one filename argument, it reads from +that file and writes to stdout. Otherwise, it reads from stdin and writes to +stdout, and prompts for each line of input, using "re>" to prompt for regular +expressions, and "data>" to prompt for data lines. +.P +The program handles any number of sets of input on a single input file. Each +set starts with a regular expression, and continues with any number of data +lines to be matched against the pattern. +.P +Each data line is matched separately and independently. If you want to do +multi-line matches, you have to use the \en escape sequence (or \er or \er\en, +depending on the newline setting) in a single line of input to encode the +newline characters. There is no limit on the length of data lines; the input +buffer is automatically extended if it is too small. +.P +An empty line signals the end of the data lines, at which point a new regular +expression is read. The regular expressions are given enclosed in any +non-alphanumeric delimiters other than backslash, for example: +.sp + /(a|bc)x+yz/ +.sp +White space before the initial delimiter is ignored. A regular expression may +be continued over several input lines, in which case the newline characters are +included within it. It is possible to include the delimiter within the pattern +by escaping it, for example +.sp + /abc\e/def/ +.sp +If you do so, the escape and the delimiter form part of the pattern, but since +delimiters are always non-alphanumeric, this does not affect its interpretation. +If the terminating delimiter is immediately followed by a backslash, for +example, +.sp + /abc/\e +.sp +then a backslash is added to the end of the pattern. This is done to provide a +way of testing the error condition that arises if a pattern finishes with a +backslash, because +.sp + /abc\e/ +.sp +is interpreted as the first line of a pattern that starts with "abc/", causing +pcretest to read the next line as a continuation of the regular expression. +. +. +.SH "PATTERN MODIFIERS" +.rs +.sp +A pattern may be followed by any number of modifiers, which are mostly single +characters. Following Perl usage, these are referred to below as, for example, +"the \fB/i\fP modifier", even though the delimiter of the pattern need not +always be a slash, and no slash is used when writing modifiers. Whitespace may +appear between the final pattern delimiter and the first modifier, and between +the modifiers themselves. +.P +The \fB/i\fP, \fB/m\fP, \fB/s\fP, and \fB/x\fP modifiers set the PCRE_CASELESS, +PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED options, respectively, when +\fBpcre_compile()\fP is called. These four modifier letters have the same +effect as they do in Perl. For example: +.sp + /caseless/i +.sp +The following table shows additional modifiers for setting PCRE options that do +not correspond to anything in Perl: +.sp + \fB/A\fP PCRE_ANCHORED + \fB/C\fP PCRE_AUTO_CALLOUT + \fB/E\fP PCRE_DOLLAR_ENDONLY + \fB/f\fP PCRE_FIRSTLINE + \fB/J\fP PCRE_DUPNAMES + \fB/N\fP PCRE_NO_AUTO_CAPTURE + \fB/U\fP PCRE_UNGREEDY + \fB/X\fP PCRE_EXTRA + \fB/<cr>\fP PCRE_NEWLINE_CR + \fB/<lf>\fP PCRE_NEWLINE_LF + \fB/<crlf>\fP PCRE_NEWLINE_CRLF +.sp +Those specifying line endings are literal strings as shown. Details of the +meanings of these PCRE options are given in the +.\" HREF +\fBpcreapi\fP +.\" +documentation. +. +. +.SS "Finding all matches in a string" +.rs +.sp +Searching for all possible matches within each subject string can be requested +by the \fB/g\fP or \fB/G\fP modifier. After finding a match, PCRE is called +again to search the remainder of the subject string. The difference between +\fB/g\fP and \fB/G\fP is that the former uses the \fIstartoffset\fP argument to +\fBpcre_exec()\fP to start searching at a new point within the entire string +(which is in effect what Perl does), whereas the latter passes over a shortened +substring. This makes a difference to the matching process if the pattern +begins with a lookbehind assertion (including \eb or \eB). +.P +If any call to \fBpcre_exec()\fP in a \fB/g\fP or \fB/G\fP sequence matches an +empty string, the next call is done with the PCRE_NOTEMPTY and PCRE_ANCHORED +flags set in order to search for another, non-empty, match at the same point. +If this second match fails, the start offset is advanced by one, and the normal +match is retried. This imitates the way Perl handles such cases when using the +\fB/g\fP modifier or the \fBsplit()\fP function. +. +. +.SS "Other modifiers" +.rs +.sp +There are yet more modifiers for controlling the way \fBpcretest\fP +operates. +.P +The \fB/+\fP modifier requests that as well as outputting the substring that +matched the entire pattern, pcretest should in addition output the remainder of +the subject string. This is useful for tests where the subject contains +multiple copies of the same substring. +.P +The \fB/L\fP modifier must be followed directly by the name of a locale, for +example, +.sp + /pattern/Lfr_FR +.sp +For this reason, it must be the last modifier. The given locale is set, +\fBpcre_maketables()\fP is called to build a set of character tables for the +locale, and this is then passed to \fBpcre_compile()\fP when compiling the +regular expression. Without an \fB/L\fP modifier, NULL is passed as the tables +pointer; that is, \fB/L\fP applies only to the expression on which it appears. +.P +The \fB/I\fP modifier requests that \fBpcretest\fP output information about the +compiled pattern (whether it is anchored, has a fixed first character, and +so on). It does this by calling \fBpcre_fullinfo()\fP after compiling a +pattern. If the pattern is studied, the results of that are also output. +.P +The \fB/D\fP modifier is a PCRE debugging feature, which also assumes \fB/I\fP. +It causes the internal form of compiled regular expressions to be output after +compilation. If the pattern was studied, the information returned is also +output. +.P +The \fB/F\fP modifier causes \fBpcretest\fP to flip the byte order of the +fields in the compiled pattern that contain 2-byte and 4-byte numbers. This +facility is for testing the feature in PCRE that allows it to execute patterns +that were compiled on a host with a different endianness. This feature is not +available when the POSIX interface to PCRE is being used, that is, when the +\fB/P\fP pattern modifier is specified. See also the section about saving and +reloading compiled patterns below. +.P +The \fB/S\fP modifier causes \fBpcre_study()\fP to be called after the +expression has been compiled, and the results used when the expression is +matched. +.P +The \fB/M\fP modifier causes the size of memory block used to hold the compiled +pattern to be output. +.P +The \fB/P\fP modifier causes \fBpcretest\fP to call PCRE via the POSIX wrapper +API rather than its native API. When this is done, all other modifiers except +\fB/i\fP, \fB/m\fP, and \fB/+\fP are ignored. REG_ICASE is set if \fB/i\fP is +present, and REG_NEWLINE is set if \fB/m\fP is present. The wrapper functions +force PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set. +.P +The \fB/8\fP modifier causes \fBpcretest\fP to call PCRE with the PCRE_UTF8 +option set. This turns on support for UTF-8 character handling in PCRE, +provided that it was compiled with this support enabled. This modifier also +causes any non-printing characters in output strings to be printed using the +\ex{hh...} notation if they are valid UTF-8 sequences. +.P +If the \fB/?\fP modifier is used with \fB/8\fP, it causes \fBpcretest\fP to +call \fBpcre_compile()\fP with the PCRE_NO_UTF8_CHECK option, to suppress the +checking of the string for UTF-8 validity. +. +. +.SH "DATA LINES" +.rs +.sp +Before each data line is passed to \fBpcre_exec()\fP, leading and trailing +whitespace is removed, and it is then scanned for \e escapes.

The +\fImatch_limit\fP number is a measure of the amount of backtracking that takes +place, and checking it out can be instructive. For most simple matches, the +number is quite small, but for patterns with very large numbers of matching +possibilities, it can become large very quickly with increasing length of +subject string.

It is recognized always. There may be +any number of hexadecimal digits inside the braces. The result is from one to +six bytes, encoded according to the UTF-8 rules. +. +. +.SH "THE ALTERNATIVE MATCHING FUNCTION" +.rs +.sp +By default, \fBpcretest\fP uses the standard PCRE matching function, +\fBpcre_exec()\fP to match each data line. From release 6.0, PCRE supports an +alternative matching function, \fBpcre_dfa_test()\fP, which operates in a +different way, and has some restrictions. The differences between the two +functions are described in the +.\" HREF +\fBpcrematching\fP +.\" +documentation. +.P +If a data line contains the \eD escape sequence, or if the command line +contains the \fB-dfa\fP option, the alternative matching function is called. +This function finds all possible matches at a given point. If, however, the \eF +escape sequence is present in the data line, it stops after the first match is +found. This is always the shortest possible match. +. +. +.SH "DEFAULT OUTPUT FROM PCRETEST" +.rs +.sp +This section describes the output when the normal matching function, +\fBpcre_exec()\fP, is being used. +.P +When a match succeeds, pcretest outputs the list of captured substrings that +\fBpcre_exec()\fP returns, starting with number 0 for the string that matched +the whole pattern. Otherwise, it outputs "No match" or "Partial match" +when \fBpcre_exec()\fP returns PCRE_ERROR_NOMATCH or PCRE_ERROR_PARTIAL, +respectively, and otherwise the PCRE negative error number. Here is an example +of an interactive \fBpcretest\fP run. +.sp + $ pcretest + PCRE version 5.00 07-Sep-2004 +.sp + re> /^abc(\ed+)/ + data> abc123 + 0: abc123 + 1: 123 + data> xyz + No match +.sp +If the strings contain any non-printing characters, they are output as \e0x +escapes, or as \ex{...} escapes if the \fB/8\fP modifier was present on the +pattern. If the pattern has the \fB/+\fP modifier, the output for substring 0 +is followed by the the rest of the subject string, identified by "0+" like +this: +.sp + re> /cat/+ + data> cataract + 0: cat + 0+ aract +.sp +If the pattern has the \fB/g\fP or \fB/G\fP modifier, the results of successive +matching attempts are output in sequence, like this: +.sp + re> /\eBi(\ew\ew)/g + data> Mississippi + 0: iss + 1: ss + 0: iss + 1: ss + 0: ipp + 1: pp +.sp +"No match" is output only if the first match attempt fails. +.P +If any of the sequences \fB\eC\fP, \fB\eG\fP, or \fB\eL\fP are present in a +data line that is successfully matched, the substrings extracted by the +convenience functions are output with C, G, or L after the string number +instead of a colon. This is in addition to the normal full list. The string +length (that is, the return from the extraction function) is given in +parentheses after each string for \fB\eC\fP and \fB\eG\fP. +.P +Note that while patterns can be continued over several lines (a plain ">" +prompt is used for continuations), data lines may not. However newlines can be +included in data by means of the \en escape (or \er or \er\en for those newline +settings). +. +. +.SH "OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION" +.rs +.sp +When the alternative matching function, \fBpcre_dfa_exec()\fP, is used (by +means of the \eD escape sequence or the \fB-dfa\fP command line option), the +output consists of a list of all the matches that start at the first point in +the subject where there is at least one match. For example: +.sp + re> /(tang|tangerine|tan)/ + data> yellow tangerine\eD + 0: tangerine + 1: tang + 2: tan +.sp +(Using the normal matching function on this data finds only "tang".) The +longest matching string is always given first (and numbered zero). +.P +If \fB/g\P is present on the pattern, the search for further matches resumes +at the end of the longest match. For example: +.sp + re> /(tang|tangerine|tan)/g + data> yellow tangerine and tangy sultana\eD + 0: tangerine + 1: tang + 2: tan + 0: tang + 1: tan + 0: tan +.sp +Since the matching function does not support substring capture, the escape +sequences that are concerned with captured substrings are not relevant. +. +. +.SH "RESTARTING AFTER A PARTIAL MATCH" +.rs +.sp +When the alternative matching function has given the PCRE_ERROR_PARTIAL return, +indicating that the subject partially matched the pattern, you can restart the +match with additional subject data by means of the \eR escape sequence. For +example: +.sp + re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/ + data> 23ja\eP\eD + Partial match: 23ja + data> n05\eR\eD + 0: n05 +.sp +For further information about partial matching, see the +.\" HREF +\fBpcrepartial\fP +.\" +documentation. +. +. +.SH CALLOUTS +.rs +.sp +If the pattern contains any callout requests, \fBpcretest\fP's callout function +is called during matching. This works with both matching functions. By default, +the called function displays the callout number, the start and current +positions in the text at the callout time, and the next pattern item to be +tested. For example, the output +.sp + --->pqrabcdef + 0 ^ ^ \ed +.sp +indicates that callout number 0 occurred for a match attempt starting at the +fourth character of the subject string, when the pointer was at the seventh +character of the data, and when the next pattern item was \ed. Just one +circumflex is output if the start and current positions are the same. +.P +Callouts numbered 255 are assumed to be automatic callouts, inserted as a +result of the \fB/C\fP pattern modifier. In this case, instead of showing the +callout number, the offset in the pattern, preceded by a plus, is output. For +example: +.sp + re> /\ed?[A-E]\e*/C + data> E* + --->E* + +0 ^ \ed? + +3 ^ [A-E] + +8 ^^ \e* + +10 ^ ^ + 0: E* +.sp +The callout function in \fBpcretest\fP returns zero (carry on matching) by +default, but you can use a \eC item in a data line (as described above) to +change this. +.P +Inserting callouts can be helpful when using \fBpcretest\fP to check +complicated regular expressions. For further information about callouts, see +the +.\" HREF +\fBpcrecallout\fP +.\" +documentation. +. +. +.SH "SAVING AND RELOADING COMPILED PATTERNS" +.rs +.sp +The facilities described in this section are not available when the POSIX +inteface to PCRE is being used, that is, when the \fB/P\fP pattern modifier is +specified. +.P +When the POSIX interface is not in use, you can cause \fBpcretest\fP to write a +compiled pattern to a file, by following the modifiers with > and a file name. +For example: +.sp + /pattern/im >/some/file +.sp +See the +.\" HREF +\fBpcreprecompile\fP +.\" +documentation for a discussion about saving and re-using compiled patterns. +.P +The data that is written is binary. The first eight bytes are the length of the +compiled pattern data followed by the length of the optional study data, each +written as four bytes in big-endian order (most significant byte first). If +there is no study data (either the pattern was not studied, or studying did not +return any data), the second length is zero. The lengths are followed by an +exact copy of the compiled pattern. If there is additional study data, this +follows immediately after the compiled pattern. After writing the file, +\fBpcretest\fP expects to read a new pattern. +.P +A saved pattern can be reloaded into \fBpcretest\fP by specifing < and a file +name instead of a pattern. The name of the file must not contain a < character, +as otherwise \fBpcretest\fP will interpret the line as a pattern delimited by < +characters. +For example: +.sp + re> </some/file + Compiled regex loaded from /some/file + No study data +.sp +When the pattern has been loaded, \fBpcretest\fP proceeds to read data lines in +the usual way. +.P +You can copy a file written by \fBpcretest\fP to a different host and reload it +there, even if the new host has opposite endianness to the one on which the +pattern was compiled. For example, you can compile on an i86 machine and run on +a SPARC machine. +.P +File names for saving and reloading can be absolute or relative, but note that +the shell facility of expanding a file name that starts with a tilde (~) is not +available. +.P +The ability to save and reload files in \fBpcretest\fP is intended for testing +and experimentation. It is not intended for production use because only a +single pattern can be written to a file. Furthermore, there is no facility for +supplying custom character tables for use with a reloaded pattern. If the +original pattern was compiled with custom tables, an attempt to match a subject +string using a reloaded pattern is likely to cause \fBpcretest\fP to crash. +Finally, if you attempt to load a file that is not in the correct format, the +result is undefined. +. +. +.SH AUTHOR +.rs +.sp +Philip Hazel +.br +University Computing Service, +.br +Cambridge CB2 3QG, England. +.P +.in 0 +Last updated: 29 June 2006 +.br +Copyright (c) 1997-2006 University of Cambridge.

This document describes the features of the test program; + for details of the regular expressions themselves, see the pcrepattern + documentation. For details of the PCRE library function calls and their + options, see the pcreapi documentation. + + +OPTIONS + + -C Output the version number of the PCRE library, and all avail- + able information about the optional features that are + included, and then exit. + + -d Behave as if each regex has the /D (debug) modifier; the + internal form is output after compilation. + + -dfa Behave as if each data line contains the \D escape sequence; + this causes the alternative matching function, + pcre_dfa_exec(), to be used instead of the standard + pcre_exec() function (more detail is given below). + + -i Behave as if each regex has the /I modifier; information + about the compiled pattern is given after compilation. + + -m Output the size of each compiled pattern after it has been + compiled. This is equivalent to adding /M to each regular + expression. For compatibility with earlier versions of + pcretest, -s is a synonym for -m. + + -o osize Set the number of elements in the output vector that is used + when calling pcre_exec() to be osize. The default value is + 45, which is enough for 14 capturing subexpressions. The vec- + tor size can be changed for individual matching calls by + including \O in the data line (see below). + + -p Behave as if each regex has the /P modifier; the POSIX wrap- + per API is used to call PCRE. None of the other options has + any effect when -p is set. + + -q Do not output the version number of pcretest at the start of + execution. + + -S size On Unix-like systems, set the size of the runtime stack to + size megabytes. + + -t Run each compile, study, and match many times with a timer, + and output resulting time per compile or match (in millisec- + onds). Do not set -m with -t, because you will then get the + size output a zillion times, and the timing will be dis- + torted. + + +DESCRIPTION + + If pcretest is given two filename arguments, it reads from the first + and writes to the second. If it is given only one filename argument, it + reads from that file and writes to stdout. Otherwise, it reads from + stdin and writes to stdout, and prompts for each line of input, using + "re>" to prompt for regular expressions, and "data>" to prompt for data + lines. + + The program handles any number of sets of input on a single input file. + Each set starts with a regular expression, and continues with any num- + ber of data lines to be matched against the pattern. + + Each data line is matched separately and independently. If you want to + do multi-line matches, you have to use the \n escape sequence (or \r or + \r\n, depending on the newline setting) in a single line of input to + encode the newline characters. There is no limit on the length of data + lines; the input buffer is automatically extended if it is too small. + + An empty line signals the end of the data lines, at which point a new + regular expression is read. The regular expressions are given enclosed + in any non-alphanumeric delimiters other than backslash, for example: + + /(a|bc)x+yz/ + + White space before the initial delimiter is ignored. A regular expres- + sion may be continued over several input lines, in which case the new- + line characters are included within it. It is possible to include the + delimiter within the pattern by escaping it, for example + + /abc\/def/ + + If you do so, the escape and the delimiter form part of the pattern, + but since delimiters are always non-alphanumeric, this does not affect + its interpretation. If the terminating delimiter is immediately fol- + lowed by a backslash, for example, + + /abc/\ + + then a backslash is added to the end of the pattern. This is done to + provide a way of testing the error condition that arises if a pattern + finishes with a backslash, because + + /abc\/ + + is interpreted as the first line of a pattern that starts with "abc/", + causing pcretest to read the next line as a continuation of the regular + expression. + + +PATTERN MODIFIERS + + A pattern may be followed by any number of modifiers, which are mostly + single characters. Following Perl usage, these are referred to below + as, for example, "the /i modifier", even though the delimiter of the + pattern need not always be a slash, and no slash is used when writing + modifiers. Whitespace may appear between the final pattern delimiter + and the first modifier, and between the modifiers themselves. + + The /i, /m, /s, and /x modifiers set the PCRE_CASELESS, PCRE_MULTILINE, + PCRE_DOTALL, or PCRE_EXTENDED options, respectively, when pcre_com- + pile() is called. These four modifier letters have the same effect as + they do in Perl. For example: + + /caseless/i + + The following table shows additional modifiers for setting PCRE options + that do not correspond to anything in Perl: + + /A PCRE_ANCHORED + /C PCRE_AUTO_CALLOUT + /E PCRE_DOLLAR_ENDONLY + /f PCRE_FIRSTLINE + /J PCRE_DUPNAMES + /N PCRE_NO_AUTO_CAPTURE + /U PCRE_UNGREEDY + /X PCRE_EXTRA + /<cr> PCRE_NEWLINE_CR + /<lf> PCRE_NEWLINE_LF + /<crlf> PCRE_NEWLINE_CRLF + + Those specifying line endings are literal strings as shown. Details of + the meanings of these PCRE options are given in the pcreapi documenta- + tion. + + Finding all matches in a string + + Searching for all possible matches within each subject string can be + requested by the /g or /G modifier. After finding a match, PCRE is + called again to search the remainder of the subject string. The differ- + ence between /g and /G is that the former uses the startoffset argument + to pcre_exec() to start searching at a new point within the entire + string (which is in effect what Perl does), whereas the latter passes + over a shortened substring. This makes a difference to the matching + process if the pattern begins with a lookbehind assertion (including \b + or \B). + + If any call to pcre_exec() in a /g or /G sequence matches an empty + string, the next call is done with the PCRE_NOTEMPTY and PCRE_ANCHORED + flags set in order to search for another, non-empty, match at the same + point. If this second match fails, the start offset is advanced by + one, and the normal match is retried. This imitates the way Perl han- + dles such cases when using the /g modifier or the split() function. + + Other modifiers + + There are yet more modifiers for controlling the way pcretest operates. + + The /+ modifier requests that as well as outputting the substring that + matched the entire pattern, pcretest should in addition output the + remainder of the subject string. This is useful for tests where the + subject contains multiple copies of the same substring. + + The /L modifier must be followed directly by the name of a locale, for + example, + + /pattern/Lfr_FR + + For this reason, it must be the last modifier. The given locale is set, + pcre_maketables() is called to build a set of character tables for the + locale, and this is then passed to pcre_compile() when compiling the + regular expression. Without an /L modifier, NULL is passed as the + tables pointer; that is, /L applies only to the expression on which it + appears. + + The /I modifier requests that pcretest output information about the + compiled pattern (whether it is anchored, has a fixed first character, + and so on). It does this by calling pcre_fullinfo() after compiling a + pattern. If the pattern is studied, the results of that are also out- + put. + + The /D modifier is a PCRE debugging feature, which also assumes /I. It + causes the internal form of compiled regular expressions to be output + after compilation. If the pattern was studied, the information returned + is also output. + + The /F modifier causes pcretest to flip the byte order of the fields in + the compiled pattern that contain 2-byte and 4-byte numbers. This + facility is for testing the feature in PCRE that allows it to execute + patterns that were compiled on a host with a different endianness. This + feature is not available when the POSIX interface to PCRE is being + used, that is, when the /P pattern modifier is specified. See also the + section about saving and reloading compiled patterns below. + + The /S modifier causes pcre_study() to be called after the expression + has been compiled, and the results used when the expression is matched. + + The /M modifier causes the size of memory block used to hold the com- + piled pattern to be output. + + The /P modifier causes pcretest to call PCRE via the POSIX wrapper API + rather than its native API. When this is done, all other modifiers + except /i, /m, and /+ are ignored. REG_ICASE is set if /i is present, + and REG_NEWLINE is set if /m is present. The wrapper functions force + PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set. + + The /8 modifier causes pcretest to call PCRE with the PCRE_UTF8 option + set. This turns on support for UTF-8 character handling in PCRE, pro- + vided that it was compiled with this support enabled. This modifier + also causes any non-printing characters in output strings to be printed + using the \x{hh...} notation if they are valid UTF-8 sequences. + + If the /? modifier is used with /8, it causes pcretest to call + pcre_compile() with the PCRE_NO_UTF8_CHECK option, to suppress the + checking of the string for UTF-8 validity. + + +DATA LINES + + Before each data line is passed to pcre_exec(), leading and trailing + whitespace is removed, and it is then scanned for \ escapes.

The match_limit_recursion number is a measure of how + much stack (or, if PCRE is compiled with NO_RECURSE, how much heap) + memory is needed to complete the match attempt. + + When \O is used, the value specified may be higher or lower than the + size set by the -O command line option (or defaulted to 45); \O applies + only to the call of pcre_exec() for the line in which it appears. + + If the /P modifier was present on the pattern, causing the POSIX wrap- + per API to be used, the only option-setting sequences that have any + effect are \B and \Z, causing REG_NOTBOL and REG_NOTEOL, respectively, + to be passed to regexec(). + + The use of \x{hh...} to represent UTF-8 characters is not dependent on + the use of the /8 modifier on the pattern. It is recognized always. + There may be any number of hexadecimal digits inside the braces. The + result is from one to six bytes, encoded according to the UTF-8 rules. + + +THE ALTERNATIVE MATCHING FUNCTION + + By default, pcretest uses the standard PCRE matching function, + pcre_exec() to match each data line. From release 6.0, PCRE supports an + alternative matching function, pcre_dfa_test(), which operates in a + different way, and has some restrictions. The differences between the + two functions are described in the pcrematching documentation. + + If a data line contains the \D escape sequence, or if the command line + contains the -dfa option, the alternative matching function is called. + This function finds all possible matches at a given point. If, however, + the \F escape sequence is present in the data line, it stops after the + first match is found. This is always the shortest possible match. + + +DEFAULT OUTPUT FROM PCRETEST + + This section describes the output when the normal matching function, + pcre_exec(), is being used. + + When a match succeeds, pcretest outputs the list of captured substrings + that pcre_exec() returns, starting with number 0 for the string that + matched the whole pattern. Otherwise, it outputs "No match" or "Partial + match" when pcre_exec() returns PCRE_ERROR_NOMATCH or PCRE_ERROR_PAR- + TIAL, respectively, and otherwise the PCRE negative error number. Here + is an example of an interactive pcretest run. + + $ pcretest + PCRE version 5.00 07-Sep-2004 + + re> /^abc(\d+)/ + data> abc123 + 0: abc123 + 1: 123 + data> xyz + No match + + If the strings contain any non-printing characters, they are output as + \0x escapes, or as \x{...} escapes if the /8 modifier was present on + the pattern. If the pattern has the /+ modifier, the output for sub- + string 0 is followed by the the rest of the subject string, identified + by "0+" like this: + + re> /cat/+ + data> cataract + 0: cat + 0+ aract + + If the pattern has the /g or /G modifier, the results of successive + matching attempts are output in sequence, like this: + + re> /\Bi(\w\w)/g + data> Mississippi + 0: iss + 1: ss + 0: iss + 1: ss + 0: ipp + 1: pp + + "No match" is output only if the first match attempt fails. + + If any of the sequences \C, \G, or \L are present in a data line that + is successfully matched, the substrings extracted by the convenience + functions are output with C, G, or L after the string number instead of + a colon. This is in addition to the normal full list. The string length + (that is, the return from the extraction function) is given in paren- + theses after each string for \C and \G. + + Note that while patterns can be continued over several lines (a plain + ">" prompt is used for continuations), data lines may not. However new- + lines can be included in data by means of the \n escape (or \r or \r\n + for those newline settings). + + +OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION + + When the alternative matching function, pcre_dfa_exec(), is used (by + means of the \D escape sequence or the -dfa command line option), the + output consists of a list of all the matches that start at the first + point in the subject where there is at least one match. For example: + + re> /(tang|tangerine|tan)/ + data> yellow tangerine\D + 0: tangerine + 1: tang + 2: tan + + (Using the normal matching function on this data finds only "tang".) + The longest matching string is always given first (and numbered zero). + + If /gP is present on the pattern, the search for further matches + resumes at the end of the longest match. For example: + + re> /(tang|tangerine|tan)/g + data> yellow tangerine and tangy sultana\D + 0: tangerine + 1: tang + 2: tan + 0: tang + 1: tan + 0: tan + + Since the matching function does not support substring capture, the + escape sequences that are concerned with captured substrings are not + relevant. + + +RESTARTING AFTER A PARTIAL MATCH + + When the alternative matching function has given the PCRE_ERROR_PARTIAL + return, indicating that the subject partially matched the pattern, you + can restart the match with additional subject data by means of the \R + escape sequence. For example: + + re> /^?(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)$/ + data> 23ja\P\D + Partial match: 23ja + data> n05\R\D + 0: n05 + + For further information about partial matching, see the pcrepartial + documentation. + + +CALLOUTS + + If the pattern contains any callout requests, pcretest's callout func- + tion is called during matching. This works with both matching func- + tions. By default, the called function displays the callout number, the + start and current positions in the text at the callout time, and the + next pattern item to be tested. For example, the output + + --->pqrabcdef + 0 ^ ^ \d + + indicates that callout number 0 occurred for a match attempt starting + at the fourth character of the subject string, when the pointer was at + the seventh character of the data, and when the next pattern item was + \d. Just one circumflex is output if the start and current positions + are the same. + + Callouts numbered 255 are assumed to be automatic callouts, inserted as + a result of the /C pattern modifier. In this case, instead of showing + the callout number, the offset in the pattern, preceded by a plus, is + output. For example: + + re> /\d?[A-E]\*/C + data> E* + --->E* + +0 ^ \d? + +3 ^ [A-E] + +8 ^^ \* + +10 ^ ^ + 0: E* + + The callout function in pcretest returns zero (carry on matching) by + default, but you can use a \C item in a data line (as described above) + to change this. + + Inserting callouts can be helpful when using pcretest to check compli- + cated regular expressions. For further information about callouts, see + the pcrecallout documentation. + + +SAVING AND RELOADING COMPILED PATTERNS + + The facilities described in this section are not available when the + POSIX inteface to PCRE is being used, that is, when the /P pattern mod- + ifier is specified. + + When the POSIX interface is not in use, you can cause pcretest to write + a compiled pattern to a file, by following the modifiers with > and a + file name. For example: + + /pattern/im >/some/file + + See the pcreprecompile documentation for a discussion about saving and + re-using compiled patterns. + + The data that is written is binary. The first eight bytes are the + length of the compiled pattern data followed by the length of the + optional study data, each written as four bytes in big-endian order + (most significant byte first). If there is no study data (either the + pattern was not studied, or studying did not return any data), the sec- + ond length is zero. The lengths are followed by an exact copy of the + compiled pattern. If there is additional study data, this follows imme- + diately after the compiled pattern. After writing the file, pcretest + expects to read a new pattern. + + A saved pattern can be reloaded into pcretest by specifing < and a file + name instead of a pattern. The name of the file must not contain a < + character, as otherwise pcretest will interpret the line as a pattern + delimited by < characters. For example: + + re> </some/file + Compiled regex loaded from /some/file + No study data + + When the pattern has been loaded, pcretest proceeds to read data lines + in the usual way. + + You can copy a file written by pcretest to a different host and reload + it there, even if the new host has opposite endianness to the one on + which the pattern was compiled. For example, you can compile on an i86 + machine and run on a SPARC machine. + + File names for saving and reloading can be absolute or relative, but + note that the shell facility of expanding a file name that starts with + a tilde (~) is not available. + + The ability to save and reload files in pcretest is intended for test- + ing and experimentation. It is not intended for production use because + only a single pattern can be written to a file. Furthermore, there is + no facility for supplying custom character tables for use with a + reloaded pattern. If the original pattern was compiled with custom + tables, an attempt to match a subject string using a reloaded pattern + is likely to cause pcretest to crash. Finally, if you attempt to load + a file that is not in the correct format, the result is undefined. + + +AUTHOR + + Philip Hazel + University Computing Service, + Cambridge CB2 3QG, England. + +Last updated: 29 June 2006 +Copyright (c) 1997-2006 University of Cambridge.

For this reason, all such +characters in testinput1 and testinput4 are escaped so that they can be used +for perltest as well as for pcretest. The special upper case pattern +modifiers such as /A that pcretest recognizes, and its special data line +escapes, are not used in these files. The output should be identical, apart +from the initial identifying banner. + +The perltest script can also test UTF-8 features. It works as is for Perl 5.8 +or higher. It recognizes the special modifier /8 that pcretest uses to invoke +UTF-8 functionality. The testinput4 file can be fed to perltest to run +compatible UTF-8 tests. + +For Perl 5.6, perltest won't work unmodified for the UTF-8 tests. You need to +uncomment the "use utf8" lines that it contains. It is best to do this on a +copy of the script, because for non-UTF-8 tests, these lines should remain +commented out. + +The other testinput files are not suitable for feeding to perltest, since they +make use of the special upper case modifiers and escapes that pcretest uses to +test some features of PCRE.

For those not familiar +// with Perl's regular expressions, here are some examples of the most +// commonly used extensions: +// +// "hello (\\w+) world" -- \w matches a "word" character +// "version (\\d+)" -- \d matches a digit +// "hello\\s+world" -- \s matches any whitespace character +// "\\b(\\w+)\\b" -- \b matches empty string at a word boundary +// "(?i)hello" -- (?i) turns on case-insensitive matching +// "/\\*(.*?)\\*/" -- .*? matches . minimum no. of times possible +// +// ----------------------------------------------------------------------- +// MATCHING INTERFACE: +// +// The "FullMatch" operation checks that supplied text matches a +// supplied pattern exactly. +// +// Example: successful match +// pcrecpp::RE re("h.*o"); +// re.FullMatch("hello"); +// +// Example: unsuccessful match (requires full match): +// pcrecpp::RE re("e"); +// !re.FullMatch("hello"); +// +// Example: creating a temporary RE object: +// pcrecpp::RE("h.*o").FullMatch("hello"); +// +// You can pass in a "const char*" or a "string" for "text". The +// examples below tend to use a const char*. +// +// You can, as in the different examples above, store the RE object +// explicitly in a variable or use a temporary RE object. The +// examples below use one mode or the other arbitrarily. Either +// could correctly be used for any of these examples. +// +// ----------------------------------------------------------------------- +// MATCHING WITH SUB-STRING EXTRACTION: +// +// You can supply extra pointer arguments to extract matched subpieces. +// +// Example: extracts "ruby" into "s" and 1234 into "i" +// int i; +// string s; +// pcrecpp::RE re("(\\w+):(\\d+)"); +// re.FullMatch("ruby:1234", &s, &i); +// +// Example: does not try to extract any extra sub-patterns +// re.FullMatch("ruby:1234", &s); +// +// Example: does not try to extract into NULL +// re.FullMatch("ruby:1234", NULL, &i); +// +// Example: integer overflow causes failure +// !re.FullMatch("ruby:1234567891234", NULL, &i); +// +// Example: fails because there aren't enough sub-patterns: +// !pcrecpp::RE("\\w+:\\d+").FullMatch("ruby:1234", &s); +// +// Example: fails because string cannot be stored in integer +// !pcrecpp::RE("(.*)").FullMatch("ruby", &i); +// +// The provided pointer arguments can be pointers to any scalar numeric +// type, or one of +// string (matched piece is copied to string) +// StringPiece (StringPiece is mutated to point to matched piece) +// T (where "bool T::ParseFrom(const char*, int)" exists) +// NULL (the corresponding matched sub-pattern is not copied) +// +// ----------------------------------------------------------------------- +// DO_MATCH +// +// The matching interface supports at most 16 arguments per call. +// If you need more, consider using the more general interface +// pcrecpp::RE::DoMatch(). See pcrecpp.h for the signature for DoMatch. +// +// ----------------------------------------------------------------------- +// PARTIAL MATCHES +// +// You can use the "PartialMatch" operation when you want the pattern +// to match any substring of the text. +// +// Example: simple search for a string: +// pcrecpp::RE("ell").PartialMatch("hello"); +// +// Example: find first number in a string: +// int number; +// pcrecpp::RE re("(\\d+)"); +// re.PartialMatch("x*100 + 20", &number); +// assert(number == 100); +// +// ----------------------------------------------------------------------- +// UTF-8 AND THE MATCHING INTERFACE: +// +// By default, pattern and text are plain text, one byte per character. +// The UTF8 flag, passed to the constructor, causes both pattern +// and string to be treated as UTF-8 text, still a byte stream but +// potentially multiple bytes per character. In practice, the text +// is likelier to be UTF-8 than the pattern, but the match returned +// may depend on the UTF8 flag, so always use it when matching +// UTF8 text. E.g., "." will match one byte normally but with UTF8 +// set may match up to three bytes of a multi-byte character. +// +// Example: +// pcrecpp::RE_Options options; +// options.set_utf8(); +// pcrecpp::RE re(utf8_pattern, options); +// re.FullMatch(utf8_string); +// +// Example: using the convenience function UTF8(): +// pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8()); +// re.FullMatch(utf8_string); +// +// NOTE: The UTF8 option is ignored if pcre was not configured with the +// --enable-utf8 flag. +// +// ----------------------------------------------------------------------- +// PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE +// +// PCRE defines some modifiers to change the behavior of the regular +// expression engine. +// The C++ wrapper defines an auxiliary class, RE_Options, as a vehicle +// to pass such modifiers to a RE class. +// +// Currently, the following modifiers are supported +// +// modifier description Perl corresponding +// +// PCRE_CASELESS case insensitive match /i +// PCRE_MULTILINE multiple lines match /m +// PCRE_DOTALL dot matches newlines /s +// PCRE_DOLLAR_ENDONLY $ matches only at end N/A +// PCRE_EXTRA strict escape parsing N/A +// PCRE_EXTENDED ignore whitespaces /x +// PCRE_UTF8 handles UTF8 chars built-in +// PCRE_UNGREEDY reverses * and *? N/A +// PCRE_NO_AUTO_CAPTURE disables matching parens N/A (*) +// +// (For a full account on how each modifier works, please check the +// PCRE API reference manual). +// +// (*) Both Perl and PCRE allow non matching parentheses by means of the +// "?:" modifier within the pattern itself. e.g. (?:ab|cd) does not +// capture, while (ab|cd) does. +// +// For each modifier, there are two member functions whose name is made +// out of the modifier in lowercase, without the "PCRE_" prefix. For +// instance, PCRE_CASELESS is handled by +// bool caseless(), +// which returns true if the modifier is set, and +// RE_Options & set_caseless(bool), +// which sets or unsets the modifier. +// +// Moreover, PCRE_EXTRA_MATCH_LIMIT can be accessed through the +// set_match_limit() and match_limit() member functions. +// Setting match_limit to a non-zero value will limit the executation of +// pcre to keep it from doing bad things like blowing the stack or taking +// an eternity to return a result. A value of 5000 is good enough to stop +// stack blowup in a 2MB thread stack. Setting match_limit to zero will +// disable match limiting. Alternately, you can set match_limit_recursion() +// which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to limit how much pcre +// recurses. match_limit() caps the number of matches pcre does; +// match_limit_recrusion() caps the depth of recursion. +// +// Normally, to pass one or more modifiers to a RE class, you declare +// a RE_Options object, set the appropriate options, and pass this +// object to a RE constructor. Example: +// +// RE_options opt; +// opt.set_caseless(true); +// +// if (RE("HELLO", opt).PartialMatch("hello world")) ... +// +// RE_options has two constructors. The default constructor takes no +// arguments and creates a set of flags that are off by default. +// +// The optional parameter 'option_flags' is to facilitate transfer +// of legacy code from C programs. This lets you do +// RE(pattern, RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str); +// +// But new code is better off doing +// RE(pattern, +// RE_Options().set_caseless(true).set_multiline(true)).PartialMatch(str); +// (See below) +// +// If you are going to pass one of the most used modifiers, there are some +// convenience functions that return a RE_Options class with the +// appropriate modifier already set: +// CASELESS(), UTF8(), MULTILINE(), DOTALL(), EXTENDED() +// +// If you need to set several options at once, and you don't want to go +// through the pains of declaring a RE_Options object and setting several +// options, there is a parallel method that give you such ability on the +// fly. You can concatenate several set_xxxxx member functions, since each +// of them returns a reference to its class object. e.g.: to pass +// PCRE_CASELESS, PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one +// statement, you may write +// +// RE(" ^ xyz \\s+ .* blah$", RE_Options() +// .set_caseless(true) +// .set_extended(true) +// .set_multiline(true)).PartialMatch(sometext); +// +// ----------------------------------------------------------------------- +// SCANNING TEXT INCREMENTALLY +// +// The "Consume" operation may be useful if you want to repeatedly +// match regular expressions at the front of a string and skip over +// them as they match. This requires use of the "StringPiece" type, +// which represents a sub-range of a real string. Like RE, StringPiece +// is defined in the pcrecpp namespace. +// +// Example: read lines of the form "var = value" from a string. +// string contents = ...; // Fill string somehow +// pcrecpp::StringPiece input(contents); // Wrap in a StringPiece +// +// string var; +// int value; +// pcrecpp::RE re("(\\w+) = (\\d+)\n"); +// while (re.Consume(&input, &var, &value)) { +// ...; +// } +// +// Each successful call to "Consume" will set "var/value", and also +// advance "input" so it points past the matched text. +// +// The "FindAndConsume" operation is similar to "Consume" but does not +// anchor your match at the beginning of the string. For example, you +// could extract all words from a string by repeatedly calling +// pcrecpp::RE("(\\w+)").FindAndConsume(&input, &word) +// +// ----------------------------------------------------------------------- +// PARSING HEX/OCTAL/C-RADIX NUMBERS +// +// By default, if you pass a pointer to a numeric value, the +// corresponding text is interpreted as a base-10 number. You can +// instead wrap the pointer with a call to one of the operators Hex(), +// Octal(), or CRadix() to interpret the text in another base. The +// CRadix operator interprets C-style "0" (base-8) and "0x" (base-16) +// prefixes, but defaults to base-10. +// +// Example: +// int a, b, c, d; +// pcrecpp::RE re("(.*) (.*) (.*) (.*)"); +// re.FullMatch("100 40 0100 0x40", +// pcrecpp::Octal(&a), pcrecpp::Hex(&b), +// pcrecpp::CRadix(&c), pcrecpp::CRadix(&d)); +// will leave 64 in a, b, c, and d. +// +// ----------------------------------------------------------------------- +// REPLACING PARTS OF STRINGS +// +// You can replace the first match of "pattern" in "str" with +// "rewrite". Within "rewrite", backslash-escaped digits (\1 to \9) +// can be used to insert text matching corresponding parenthesized +// group from the pattern. \0 in "rewrite" refers to the entire +// matching text. E.g., +// +// string s = "yabba dabba doo"; +// pcrecpp::RE("b+").Replace("d", &s); +// +// will leave "s" containing "yada dabba doo". The result is true if +// the pattern matches and a replacement occurs, or false otherwise. +// +// GlobalReplace() is like Replace(), except that it replaces all +// occurrences of the pattern in the string with the rewrite. +// Replacements are not subject to re-matching. E.g., +// +// string s = "yabba dabba doo"; +// pcrecpp::RE("b+").GlobalReplace("d", &s); +// +// will leave "s" containing "yada dada doo". It returns the number +// of replacements made. +// +// Extract() is like Replace(), except that if the pattern matches, +// "rewrite" is copied into "out" (an additional argument) with +// substitutions. The non-matching portions of "text" are ignored. +// Returns true iff a match occurred and the extraction happened +// successfully.
