Augmentations

Augmentations is a tiny Rails plugin to easily extend a model (or other class) with instance methods and class methods, as well as running class methods like belongs_to at extend time.

It's basically like includeing a module, but you can also define class methods and call class methods as you would in the class itself, without (ab)using the self.included hook and thus with less boilerplate.

Use it like

class User < ActiveRecord::Base
  augment Shared::Pingable, User::PasswordResetExtension
end

with modules like

module User::PasswordResetExtension
  augmentation do

    has_many :password_resets

    def self.a_class_method
      # …
    end

    def an_instance_method
      # …
    end

  end
end

This particular module would be found in app/models/user/password_reset_extension.rb.

(If you want to weird things up in the name of fewer lines of code, the Ruby parser will accept

module User::PasswordResetExtension augmentation do

    …

end end

too.)

Module parameters

Want support for module parameters, like

augment Shared::Pingable, pong: false

? Try this!
