Ruby_parser 2.3.1 Released

ruby_parser version 2.3.1 has been released!

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)))))
