Lua, Function List on Notepad++

New feature for the notepad++ version 6.5.2! it could shows you the function list for the currently viewed document, function list for php, c++, c, perl is supported out-of the box

For those of you Lua programmer using notepad++, here is a simple how to add Lua function list to the notepad++

1. Locate your %APP_DATA% folder, if you are using the zip distribution, go to your extraction directory
2. Open functionList.xml
3. On NotepadPlus >> functionList >> associationMap , see the commented LangID for LUA, on my installation it is 23
4. Add the following
   <association langID="23" id="lua_function"/> on that section
5. Creating the parser:
   on NotepadPlus >> functionList >> parsers add the following section
   

   <parser id="lua_function" displayName="Lua" commentExpr="((--\[\[.*--\]\])|(--.*?$))">
    <function
     mainExpr="function\s+(\w+[:\.])?(\w+\s*\(\s*[\w,\s]*\s*\))"
     displayMode="$className->$functionName">
     <functionName>
      <nameExpr expr="\w+\s*\(\s*[\w,\s]*\s*\)"/>
     </functionName>
     <className>
      <nameExpr expr="[\w]+(?=[\s]*[:.])"/>
     </className>
    </function>
   </parser>
   

6. Warning: if you copy paste xml content on line 5, please make sure that the xml properties are in one line, if they appear to be 2 line, it is because html page wordwrapping ;)
7. Restart notepad++
8. Open your lua file, open function list panel (Menu >> View >> FunctionList)

If the functions is not showing, chances are :

1. You are using Gary's mod lua lexer.. uninstalling it should overcome the problem
2. Wrong language ID noted from step 3

That's all! :)

Have fun!
