aninder / redflag.rb
Created March 5, 2013 12:05
fix for bug in "metaprogramming ruby" book code snippet on page 121 (creating DSL). It calls events of previous files again for each new file loaded and redflag2.rb is another way creating it.
lambda {
setups = []
events = {}
Kernel.send :define_method, :event do |name, &block|
events[name] = block
end
Kernel.send :define_method, :setup do |&block|
setups << block
