🕷 software releases

by ryan davis


ruby_parser version 3.0.2 has been released!

Published 2012-11-21 @ 01:24

ruby_parser (RP) is a ruby parser written in pure ruby (utilizing racc–which does by default use a C extension). RP’s output is the same as ParseTree’s output: s-expressions using ruby’s arrays and base types.

As an example:

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


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)))
