Aah, a classic! I can spot it on my shelf, but it looks a bit dusty. ;-)

I dont follow you here. I'm looking into SableCC 2.14.1 so if you've
updated the AST names that wouldn't be a problem, eh? I guess I've
misunderstood something.

I've been developing rular for some time now. It's similar to SableCC but
written in (the object-oriented scripting language,
www.ruby-lang.org) Ruby. rular is acronym for RUby framework for LAnguage
Recognition. To possibly enhance my system and compare it to SableCC I
want to take a look at the SableCC sources. Before "diving in" I wanted to
ask you guys so that I don't loose myself in there... ;-)

If/when I release rular I can post a note on this list, if you think its
appropriate.
