Thanks Roland,
ParseTree and Ripper are file source parsers,
That's incorrect for ParseTree, which essentially just turned MRI's AST
into a Ruby data structure, ie. it worked at runtime without looking at
the source.
Merb had a feature, long ago, called action arguments, which used
ParseTree to get at argument names (the docu link is gone, but I wrote
about it here
http://www.infoq.com/news/2009/07/ruby192-preview1-rubyversions )
There's a JRuby version of ParseTree (oddly named 'jParseTree') that I
wrote a few years ago, but it hasn't been updated in quite a while, and
probably doesn't run in its current state (unless the JRuby AST has been
stable for the last 3 years).
Hm... come to think of it... this
http://www.infoq.com/news/2009/07/ruby192-preview1-rubyversions
mentions that Ruby 1.9.2 might get Method#parameters, which should do
what you want. No idea about the status of this right now;
