improve Lua lexer

teest file added. codetree-class-init.zip

questions for who knows Lua. @Artem3213212 @dinkumoil @davidhealey

1. file has many “self:mmmm” so maybe hilite word “self”? in which style- keyword (bold black) or std word (purple)?

1b. hilite “self” in all lines?

  self:reset()
  self.filename = filename
  self.lines = {}

1. file has many “function Doc:mmm()” so maybe move all funcs for Doc: to new code tree node “Doc”?

2. Lua allows more “:” chars in func name? eg “Doc:nnn:mmm”, “Doc:aa:bb:cc:dd”?

Yes, unnamed or anonymous functions should be invisible in code tree. In your example nn = function(x) return x end the function is anonymous, so don’t show it.

any more notes, pls?

No, everything seems to be fine. Thank you!
