Windcharger

Windcharger is a small library to easily make objects that transform input via many methods.

Install as usual: gem install windcharger or add gem 'windcharger' to your Gemfile.

Declare methods as attributes by extending Windcharger::Attributes and preceding methods with attribute:

require 'windcharger'

class MyTransformer
  extend Windcharger::Attributes

  attribute
  def foo; end

  attribute
  def bar; end

  def not_an_attribute; end
end

MyTransformer.attributes  #=> [:foo, :bar]

This isn’t very useful on its own, so include Windcharger::HashTransformer to get the transform method:

require 'windcharger'

class MyTransformer
  extend Windcharger::Attributes
  include Windcharger::HashTransformer

  attribute
  def foo
    :the_foo
  end

  attribute
  def bar
    :walked_into_a_bar
  end

  def qux
    1
  end

  attribute :qax, :qux

  def qax
    2
  end

  def not_an_attribute
    42
  end
end

my_transformer = MyTransformer.new
my_transformer.transform
#=> {
#     :foo => :the_foo,
#     :bar => :walked_into_a_bar,
#     :qax => 2,
#     :qux => 1,
#   }

Add an initialize that takes some input and then transform it to each attribute in their respective methods and you have a nice transformer object.
