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.
