ruby_parser version 2.1.0 has been released!

Published 2011-08-15 @ 16:47

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)
  if arg1 == 0 then
    return 1
  end
  return 0
end

becomes:

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