Here is general parser/lexer I did:
http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/138450
It is quite functional right now. I see no reason you couldn't
write up the grammar for Ruby and do whatever you want to the
parse tree (during parsing or after).
I'll be renaming the project to 'grammar' and putting it on
rubyforge. The primary things on my list are some additions to
make creating a lexer easier and a better IO interface
(rubyforge project 'cursor'). The same classes will be used
for the parser and lexer - they just parse different things -
tokens vs. characters.

Hello ruby-talk,
Does any Ruby parser existother then the internal one inside
the ruby
interpreter. I found a few projects but most of them seems to
be dead.bRuby (not really a parser) and Ripper are old and not
touched since
2003. I need some positional data for the AST and a defined
way to
traverse the AST. Even the ParseTree project forgets to
traverse some
branches inside the tree.--
