What is the status of the Ruby Grammar Project? This list is obviously
dead silent, but in reading different things I wonder if work is being
done on other related projects. For example, are people working on
Ripper? What is the status of that? What about ANTLR's Ruby bindings
themselves. ANTLR's wiki page on them makes them sound incomplete, and
the only other thing I can find is some two year old blog posts on
split-s.

Oh hey... I forgot I was on this mailing list.

Um. I should probably mention that I finished and released 1.0.0 of  
ruby_parser, implemented with racc and a pure ruby lexer. It is  
available at:

Well, I think there's generally a lack of folks interested in working on it.

I think the best bets right now are Ryan's parser and the XRuby parser 
(based on ANTLR2 with an ANTLR3 version in the works). JRuby, Ruby.NET, 
and IronRuby all have ports of the Ruby 1.8 parser to C-like language 
parser generators with hand-written lexers.

XRuby's parser unfortunately has almost nobody working on it, despite 
being the most complete LL parser I know of. I would love to see folks 
contribute to it.

I think Ryan's parser is only missing a few bits and pieces right now, yes?
