Is this possible in one regex expression?
Yes, assuming you're using 1.1b12 you can name the captures, this is done like this: match = "(\b(function)\s+()[a-zA-Z_]\w*)\s*\([^\)]*(\))"; captures = { 1 = { name = "storage.type"; }; 3 = { name = "storage.type"; }; };
That way capture #1 and #3 gets “storage.type” as the name.
Is there some way to match something by looking for a leading (or trailing) indicator without including the indicator in the match?
You can both use look-ahead and look-behind assertions in the regular expression.
E.g.: match = "foo(?=bar); or match = "(?<=foo)bar;
The first one matches foo, when followed by bar. The second matches bar, when preceded by foo.
I'm currently using this regex to successfully capture the whole thing: match = "\b(function)\s+([a-zA-Z_]\w*)\s*\([^\)]*\)";
Another approach is to use begin/end matches. E.g.: begin = "\b(function)\s+([a-zA-Z_]\w*)\s*\("; end = "\)";
You'd still need to put a capture around these patterns and name that capture (to get a name associated only to these two things), but it allows you to provide a new set of rules for the stuff between the begin/end patterns using e.g.: patterns = ( { name = "support.class"; match = "\b(String|MenuItem|...)\ \b"; }, ... );
