Is there a parser for ruby syntax that identifies the exact ranges of
characters for each nonterminal? I need this to instrument ruby code.
Just getting line numbers is not adequate.
Thanks,
Jonathan

irb has a lexer that is pretty easy to use. I think it only stores
the beginning location, though, but it should be easy to get the
range.
No example handy, sorry… if you can’t figure it out, I can assist,
though…

dunno if this helps, but you may find useful ripper
look at [ruby-talk: 86056] for the latest reference to it

Referring to example in www.ruby-talk.org/83656
If the token has an associated value, use length of value
or start position of following token.
Comments are followed by TkNL.
Strings end where the next token begins
(e.g. TkSPACE / TkCOMMA …)

Thanks but I need a parse, not a lexical scan. I am looking for all
subexpressions, not just the tokens.
