Defined in:
lib/pakyow/support/extension.rb

Overview

Makes it easier to define extensions.

Examples:


module SomeExtension
  extend Pakyow::Support::Extension

  # only allows the extension to be used on descendants of `SomeBaseClass`
  restrict_extension SomeBaseClass

  apply_extension do
    # anything here is evaluated on the object including the extension
  end

  class_methods do
    # class methods can be defined here
  end

  prepend_methods do
    # instance methods you wish to prepend can be defined here
  end

  # define instance-level methods as usual
end

class SomeClass < SomeBaseClass
  include SomeExtension
end
