Printing the source code of a Ruby block

by

You can do this with Ruby2Ruby which implements a to_ruby method.

require 'rubygems'
require 'parse_tree'
require 'parse_tree_extensions'
require 'ruby2ruby'

def meth &block
  puts block.to_ruby
end

meth { some code }

will output:

"proc { some(code) }"

I would also check out this awesome talk by Chris Wanstrath of Github http://goruco2008.confreaks.com/03_wanstrath.html He shows some interesting ruby2ruby and parsetree usage examples.
