[Help] Function list doesn't support my language.

MAPJe71

Could you supply a code example?

SalviaSage

This is my code, already integrated into functionlist and working.

Just need to parse out the comments, so they dont appear in thefunction list.

		<!-- Basic lua parser for functionList.xml in Notepad++ 6.5.3 -->
		<!-- See http://notepad-plus-plus.org/features/function-list.html -->
		<parser id="lua_function" displayName="Lua" commentExpr="--.*?$">

				openSymbole="\{"
				closeSymbole="\}"
				displayMode="node">

				</className>
			</function>

@SalviaSage
Sigh, a Lua source code example containing function definitions in comment that the parser should not find.

SalviaSage

This one for example:

--[[
	Resize and hide any unusable bag slots in the frame.
		This function needs to know about the size and layout of the frame
--]]

“needs” here is recognized as a function because it is right after the word “function”

and here:

–this function is there so that it can be overriden

the word "is" is recognized here also.

Change the parsers header from

        <parser id="lua_function" displayName="Lua" commentExpr="--.*?$">

to

			<parser
				displayName="Lua"
				id         ="lua_function"
				commentExpr="(?x)                                               # free-spacing (see `RegEx - Pattern Modifiers`)
								(?s:                                            # Multi Line Comment
									(?&lt;!-)-{2}                               # - start-of-comment indicator with
									\x5B(?'MLCLVL'=*)\x5B                       #   ...specific level
									.*?                                         # - whatever, until
									\x5D\k'MLCLVL'\x5D                          # - end-of-comment indicator of equal level

I just entered this code into the functionlist.xml as such:

It didn’t change anything. I think I indented right.
It errors on this line <nameExpr expr=“((?<=function)[\s]+[.:\w]+)|(([.\w]+)(?=([\s]*=[\s]*function)))”/>
according to the online xml validator.

MAPJe71

Change the ?<= to ?<=.

SalviaSage

I don’t think that worked.

This one works for me (no classes/tables yet though):

I just tested this new code here, and it doesn’t catch the comments or the strings incorrectly.

Thanks a lot for this!

I am trying to combine the table support from the code above into this new code.
