Similar to ruby2ruby this library allows to parse Ruby code, modify and recompile it back to Ruby.

Differences:

• uses Ripper for parsing (shipped with Ruby 1.9)
• produces a full object-oriented representation of the Ruby code

• A higher level API is to facilitate selecting parts of the parse tree

# module Monty::Python ... end code.find_module('Monty::Python') 

# class Monty::Python ... end code.find_class('Monty::Python') 

# class Monty < Abc::Blip ... end code.find_class('Monty', :superclass => 'Abc::Blip') 

# my_block do ... end code.find_block('my_block') 

# my_block do |v| ... end code.find_block('my_block', :block_params => ['v']) 

 # my_block 7, 'a' do ... end code.find_block('my_block', :args => [7, 'a']) 

 # my_block 7, 'a', :k => 32 do |v| ... end code.find_block('my_block', :args => [7, 'a', {:k => 32}], :block_params => ['v']) 

# my_block :a => 7, b => 3 do |v| ... end block_node = code.find_block('my_block', :args => [{:a => 7, 'b' => 3}]) 

 # my_block ['a', 'b'] do |v| ... end block_node = code.find_block('my_block', :args => [{:array =>['a', 'b']}])
