I guess it sounds useful. You know, at this rate we'll need a separate section for Lua stuff. Approved.

Useful for parsing JASS files actually ; ).

I was thinking that there should have been a separate Lua section from the start : ).

Updated Find Line to run off of file header >: D.

 

[Nestharus]

And updated again :O


Updated all of the other lua resources too (just didn't reply)


UnitIndexer and UnitEvent didn't need updates >: D.

Updated to be a plain search so that things like [ could be searched for in the string.
