ruby2ruby provides a means of generating pure ruby code easily from RubyParser compatible Sexps. This makes making dynamic language processors in ruby easier than ever!

Clean, simple SexpProcessor generates ruby code from RubyParser compatible sexps.
require 'rubygems' require 'ruby2ruby' require 'ruby_parser' require 'pp' ruby = "def a\n puts 'A'\nend\n\ndef b\n a\nend" parser = RubyParser.new ruby2ruby = Ruby2Ruby.new sexp = parser.process(ruby) pp sexp p ruby2ruby.process(sexp.deep_clone) # Note: #process destroys its input, so # #deep_clone if you need to preserve it ## outputs: s(:block, s(:defn, :a, s(:args), s(:scope, s(:block, s(:call, nil, :puts, s(:arglist, s(:str, "A")))))), s(:defn, :b, s(:args), s(:scope, s(:block, s(:call, nil, :a, s(:arglist)))))) "def a\n puts(\"A\")\nend\ndef b\n a\nend\n"
+ sexp_processor + ruby_parser
+ sudo gem install ruby2ruby
To get started all you need is a checkout, rake, and hoe. The easiest way is:
% git clone seattlerb/ruby2ruby # assumes you use the `hub` wrapper. % gem i rake hoe % rake install_plugins # installs hoe-seattlerb & isolate % rake install_plugins # installs minitest (referenced from hoe-seattlerb)
From here you should be good to go. We accept pull requests on github.
