eigenclass

Utility methods for modifying a ruby object’s eigenclass/metaclass

Installation

gem install eigenclass

Usage

This gem allows you to define class level accessors, readers, and writers

class SomeClass
  eattr_accessor :test_accessor
  eattr_reader :test_reader
  eattr_writer :test_writer
end

SomeClass.test_accessor = 'testing'

You can also dynamically create class methods

SomeClass.class_eval do
  define_class_method 'test_class_method' do
    'test'
  end
end

SomeClass.test_class_method # returns 'test'

You can even evaluate a block of code inside the scope of an object’s eigenclass

SomeClass.eigenclass_eval do
  attr_accessor :test_eigenclass_eval
end

SomeClass.test_eigenclass_eval = true

A reference to any object’s eigenclass can be accessed by calling

SomeObject.eigenclass

Note on Patches/Pull Requests

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but

  bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
