One way to avoid this is to use the + 'volatile' keyword with the variable. Then the compiler must + accesss it from memory each time it is accessed. + <blockquote> + <pre> +volatile EXPRTYPE k; + +/* Add variable to the list */ +exprValListAddAddress(list, "k", (EXPRTYPE*)&k); + +k = 0.0; + +/* Evaluate expression */ +for(int x = 0; x < 100; x++) + { + exprEval(expr, &result); + + doSomething(k); + } + </pre> + </blockquote> + </li> + +</div> + +<div align="left" class="container"> + <h2><a name="Example">Example Use with Fast Variable Access</a></h2> + + <p>This is an example application of this library.

The only C++ part is the C++ Wrapper which +encapsulates the complexity of the library usage. + +ExprEval supports the parsing of multiple expressions +in a single expression string. Each sub-expression +must end with a semicolon. It also supports the use +of variables, constants, and functions. Functions +can take multiple arguments. These arguments can +also be expressions. + +ExprEval is very fast. It first parses the expression +string into a tree of actions to take. After it has +been parsed, an expression can be evaluated many times +over an over. + +Functions, variables, and constants are stored in +their own seperate lists. This makes is where the +lists can be shared among multiple expression objects. +A function list can add all the functions needed, and +then be added to each expression object, instead of +added each needed function to each object. The same +goes for constant lists. Variable lists make it where +one expression can depend on a variable set in another. + + +Saturday, July 1, 2006 +---------------------- +Version 2.6 + +* Added a new value list function 'exprValListGetNext' that can be used to + enumerate the items in a value list. Any of the items not needed (name, + value, or address) can be NULL. For example: + + char *name; + EXPRTYPE val; + void *cookie; + + cookie = exprValListGetNext(vlist, &name, &value, NULL, NULL); + while(cookie) + { + /* Do something with name and value */ + cookie = exprValListGetNext(vlist, &name, &value, NULL, cookie); + } + + You must make sure not to actually edit the returned name, because it is a + pointer into the value list to the name. This can also be used to have one + value list store globals. Global variables can be added to a value list, then + additional lists can be created, and before any variables are added + or the expression is parsed, the global list can be enumerated for name and + address and the exprValListAddAddress can be used to add them. This way, + expressions can have their own private list, but some variables may be shared + on each expression through the global list. This is useful especially if the + globals are not known at compile time, but can be adjusted by the user. + For example: + + exprValList *globals; + exprValList *v1; + exprValList *v2; + char *name; + EXPRTYPE *addr; + void *cookie; + + exprValListCreate(&globals); + /* Add variables to the list, perhaps read from a user file or something */ + + exprValListCreate(&v1); + cookie = exprValListGetNext(globals, &name, NULL, &addr, NULL); + while(cookie) + { + exprValListAddAddress(v1, name, addr); + cookie = exprValListGetNext(globals, &name, NULL, &addr, cookie); + } + + +Friday, June 30, 2006 +--------------------- +Version 2.5 + +* Added a new value list function 'exprValListAddAddress'. This function adds + a named value to the list, but uses the addresss of a stack variable. The + stack variable is then used to set/get the value instead of the internal list + value. You must ensure that the stack variable exists as long as it is used + by the expression. This can permit, for example, a value name to be shared + with two different value lists like such: + + EXPRTYPE global_value; + exprValListAddAddress(vlist, "global", &global_value); + exprValListAddAddress(vlist2, "global", &global_value); + + Like this, the value can be directly accessed by the application, and each + value list will share it. This can also be used to replace code from this: + + EXPRTYPE *a; + exprValListAdd(vlist, "var", 0.0); + exprValListGetAddress(vlist, "var", &a); + + To look like this: + + EXPRTYPE a; + exprValListAddAddress(vlist, "var", &a); +* Added a value list function exprValListSet to set the value of a variable + (using the slow search method). This is because the add functions now return + and error if the item (function/value) already exists instead of setting the + value of the item. You can still use the fast direct access method. +* Changed internal lists for function and value lists from binary trees to + linked lists. + + + + +Thursday, May 4, 2006 +--------------------- +Version 2.0 + +* All internal functions are evaluated directly in the exprEvalNode call. + This gives some speed increase. +* Removed parameter and reference count macros as well as functin creation + macro. Parameter and reference count information can be set when adding + a function solver. +* Removed exprMsgFuncType, since it is unused by the library. +* Changed much of the internal names from one-letter variable names to + more meaningful names. + +Thursday, December 1, 2005 +-------------------------- +Version 1.8 + +* Added support for the ^ operator to raise to a power. + The pow function can still be used. +* Moved basic math code (add,subtract,multiply,divide,negate,exponent) + and multiple expression support from function solvers to the exprEvalNode + function. + +Tuesday, November 22, 2005 +-------------------------- +I still haven't been keeping up with history much. + +* Removed < and > as comments. Instead use # as a + comment to the end of the line +* Added function exprGetErrorPosition to get start and + end position of parse error. + +Monday, May 3, 2004: Version 1.0 +--------------------------------- +This is a pretty bad time to start the history part since +ExprEval is pretty much up and running and very operational. + +* Added macro EXPR_MAJORVERSION +* Added macro EXPR_MINORVERSION +* Added function exprGetVersion +* Added macro to make declaring functions easy: + EXPR_FUNCTIONSOLVER(func_name) +* Added support for passing variable references to functions + with the ampersand. Example: minmax(1,2,3,&min,&max) +* Added macros for reference support: + EXPR_REQUIREREFCOUNT + EXPR_REQUIREREFCOUNTMIN + EXPR_REQUIREREFCOUNTMAX + EXPR_REQUIREREFCOUNTRANGE +* Added feature to disable assigning to a variable with the + same name as a constant. +* Added feature to enable applications to change the value of + a constant while the expression can not. You must add + any constants to the constant list BEFORE you parse the + expression.
