The goto statement and the label definition (::labelname::) are missing. https://www.lua.org/manual/5.3/manual.html#3.3.4
The "table.member" and "table:member" references before and after the function keyword is not recognized. https://i.imgur.com/zXqJQPn.png

Good suggestions, will work on it.

Updated lexer, pls test, in GH
https://github.com/Alexey-T/CudaText/tr ... ata/lexlib

keywords (not and or....) were already OK.
symbol-operators were OK too, hilited as symbols, do you want separate style for them? why?

Fixed now, updated lex in Github.

> The "table.member" and "table:member" references before and after the function keyword is not recognized.

It will be bad if I won't hilite them as one token + code-tree won't show these items (code-tree needs one token for func name, token with .: ).
