This does not looks right: function(varX - 1,varZ + 2, varA := 10)

to solve it: go to grammar folder>autohotkey.cson>line 79 i have this in my version: match: "(\\w+)([(])([\\w\\s\",]*)([)]) you want to leave it like this: match: "(\\w+)([(])([\\w\\s\\+\\*\",.:=-]*)([)]) and restart Atom

also there's a lot of symbols that you can't put inside the parameters, so this looks bad too: function("this is a string that has () and [ and { and ; and \ and and and and", parameter 2) I don't have enough regex knowledge to fix that
