An alternate take on the delegation class macro provided by ActiveSupport. Updated with Ruby 2.0's caller_locations.
#!/usr/bin/env ruby
class Module

def delegate(*args)
dest, prefix = _extract_valid_delegation_options(args.pop)
_define_delegators(caller_locations.first, prefix, dest, args)

ernie / reorder.rb
Created September 6, 2013 19:20
So, I was in the process of writing this code today, and went on a wild goose chase due to this weird error message. I'd expected to see the nil come back from String#index, and give a different error, but no NilClass to be found in this error. String isn't even a type that String#index can return. It should only return a Fixnum or nil. Instead:…
#!/usr/bin/env ruby
require 'minitest/autorun'
class Reorder
SINGLE_CHAR = /./
def initialize(word, order)
@word, @order = word, order
end
