name: ruby_parser
description: ruby_parser (RP) is a ruby parser written in pure ruby (utilizing
racc--which does by default use a C extension). It outputs
s-expressions which can be manipulated and converted back to ruby via
the ruby2ruby gem.

As an example:

    def conditional1 arg1
      return 1 if arg1 == 0
      return 0
    end

becomes:

    s(:defn, :conditional1, s(:args, :arg1),
      s(:if,
        s(:call, s(:lvar, :arg1), :==, s(:lit, 0)),
        s(:return, s(:lit, 1)),
        nil),
      s(:return, s(:lit, 0)))

Tested against 801,039 files from the latest of all rubygems (as of 2013-05):

* 1.8 parser is at 99.9739% accuracy, 3.651 sigma
* 1.9 parser is at 99.9940% accuracy, 4.013 sigma
* 2.0 parser is at 99.9939% accuracy, 4.008 sigma
* 2.6 parser is at 99.9972% accuracy, 4.191 sigma
* 3.0 parser has a 100% parse rate.
  * Tested against 2,672,412 unique ruby files across 167k gems.
  * As do all the others now, basically.
