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.

Inspired by ctemplate, Mustache is a framework-agnostic way to render logic-free views. As ctemplates says, "It emphasizes separating logic from presentation: it is impossible to embed application logic in this template language. Think of Mustache as a replacement for your views. Instead of views consisting of ERB or HAML with random helpers and arbitrary logic, your views are broken into two parts: a Ruby class and an HTML template.
