I found some intrsting thing, maybe bug. I instruct mod_lua to seek for scripts in
$${script_dir}/lua:

# cat lua.conf.xml
<configuration name="lua.conf" description="LUA Configuration">
  <settings>

    <param name="module-directory" value="/usr/local/lib/lua/5.1/?.so"/>
    <param name="module-directory" value="/usr/local/lib/?.so"/>
    <param name="script-directory" value="$${script_dir}/lua/?.lua"/>

    <param name="xml-handler-script" value="gen_dir_user_xml.lua"/>
    <param name="xml-handler-bindings" value="directory"/>

  </settings>
</configuration>

But in loading process i got next error message in logfile:

freeswitch.log:
2014-10-03 17:02:05.683593 [ERR] mod_lua.cpp:203 cannot open /usr/local/share/freeswitch/scripts/gen_dir_user_xml.lua: No such file or directory

2014-10-03 17:02:05.684196 [ERR] mod_lua.cpp:269 LUA script parse/execute error!

I put my lua scripts in right place (as described in config):
# ls -la /usr/local/share/freeswitch/scripts/lua/gen_dir_user_xml.lua
-rw-r--r--  1 root  wheel  1708  3 окт 16:17 /usr/local/share/freeswitch/scripts/lua/gen_dir_user_xml.lua

But FS seek for it in $${script_dir} place, where no my script:
# ls -la /usr/local/share/freeswitch/scripts/gen_dir_user_xml.lua
ls: /usr/local/share/freeswitch/scripts/gen_dir_user_xml.lua: No such file or directory

When my FF starts, it evals path from config right:
freeswitch@voip-bsd-01.local> eval $${script_dir}/lua/
/usr/local/share/freeswitch/scripts/lua/

I can solve this problem simply by putting script to $${script_dir} (I tried, it works), but after that i loose possibility to sort my scripts.

Any thinks about?
