get regex from antlr grammar

Question

there is a way to get regexes from an antlr grammar file? I have a langage grammar and I need token regexes to make an ace editor?

thanks in advance

Answer 1

Sure. Build a parser for ANTLR grammars (ANTLR itself in fact already does this) that constructs a tree for the regexps.

You'll still have to translate those regexps into a form compatible for your ACE editor. Such a project is likely to take you days.

I think the effort to do this likely exceeds the cost to simply convert the regexes by hand. I already said this to you once.
