It's really sort of a meta-project, with our ultimate deliverable being a formal specification of the grammar, producing a useful ANTLR 3 reference grammar as part of that process. We've got some incomplete parsers in SVN, but none of those are "the" RubyGrammar grammar at this point. > - How does it compare to the RubyFront grammar?

The RubyFront grammar is by far the most complete of any of the ANTLR grammars I've seen. > - Is this project still being actively worked?

If JRuby also plans to use it, then you should think about either merging JRuby and XRuby, or factoring RubyFront out into a separate project so that other Ruby implementation projects could use it easily (ZeroOneInfinity and all that). If you guys do feel it's best to factor out RubyFront, I'd be happy to provide the The Ruby Grammar Project, its SVN repository, and its mailing list as a home for the effort, and provide what material assistance I can, including making people project admins. I'm just here to facilitate this Ruby Grammar thing. As long as it gets done I'm not too particular about the details. -mental
