ruby\_parser version 2.0.5 has been released!

- [http://parsetree.rubyforge.org/](http://parsetree.rubyforge.org/)

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)))))
