ATTRIBUTE-DRIVEN by Aman King

bitbucket.org/amanking/attribute-driven/

A module that (1) allows you to mention a list of attributes in a class, (2) provides reader methods for the attributes, (3) allows initialization of the class via a hash argument that gives values for the attributes, (4) overrides equals and hash method to check for field equality

Usage:

require ‘attribute_driven’ class Money

include AttributeDriven
attributes :value, :currency
# initializes_with :value, :currency #=> only adds the initialize method
# equality_based_on :value, :currency #=> only overrides equality methods and hash

end

money = Money.new(:value => 20, :currency => ‘USD’) #=> #<Money:0x5138e4 @value=20, @currency=“USD”> money.value #=> 20 money.currency #=> “USD” money == Money.new(:value => 20, :currency => ‘USD’) #=> true

(see test/attribute_driven_test.rb for more)
