Does any Ruby parser exist ?

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.

FG> Ripper has been merged into 1.9 and is part of the windows one-click
FG> installer -- its grammar rules will thus always be up-to-date in the future.

How compatible are these rules with 1.8 ?

FG> I think that Ripper will do what you want, but I think you will have to

Okay i will see if i can use Ripper, as i must add it to a running
1.8.2 ruby system.

FG> That aside there is also a few lexers like the IRB one and the one used
FG> by the syntax library that does Ruby code highlighting.

They are all ugly hacks that are just doing a fraction of the ruby
grammer. Good for there special purpose but i need something
different. And none of them can give me line/column positions of an
indentifier.

Really? Where?

Please respond directly, or better, file a bug at http://
rubyforge.org/projects/parsetree/

Thanks anyway for your help
