Ruby Parser

[Nathan Weston]

Are there any reasonably mature ruby parsers out there (preferably
written in ruby or with a ruby interface)?

I googled a little bit and searched RAA but I didn't come up with
much.

if you mean 'parser for the ruby syntax' I think you have to rely on
parse.y in the interpreter distribution..
Many people is looking for this

are you going to write a ruby compiler?

pseudo BNF for Ruby-1.4 is here
http://www.ruby-doc.org/docs/Manual/man-1.4/yacc.html

I guess 'jruby' has a ruby parser?

Actually, the immediate project I had in mind was a tool for searching
ruby source code -- to find, for example, the definition of a class or
method, all uses of an instance variable, etc.

I don't know if it does. But I would expect the Ruby manuals to have a
grammar for Ruby. It would then be up to you to convert it into whatever
type of grammar you require.

BTW, A VM based Ruby could be interesting.
