well, ctags is certainly a viable option. but i recently wrote a
little tool [1] that traces added methods and gives you the method
source right in an interactive irb session. why resort to some
external tool when we have ruby :-)

add this to your ~/.irbrc:

  require 'rubygems'
  require 'nuggets/util/added_methods/init'

(for production use, you might want to put some conditional around
that; otherwise it would be loaded in every session, which at least
slows things down a bit - not to mention any possible bugs or
side-effects.)

then in script/console:

  require 'spec/rails'  # if not already done
  puts AddedMethods[:mock_model]

it's part of the ruby-nuggets gem, available from rubyforge [2] or
our own gem server [3].
