How to prepend classmethods

Question

This question directly relates to this one. But I tried to break it down to the base problem and I didn\'t want to enter even more text into the other question box. So here

Answer 1

The problem is that even though you're prepending the module, ClassMethods is still getting extended in. You could do this to get what you want:

module Extensions
  module ClassMethods
    def bar
      'Extended Bar!'
    end  
  end  

  def self.prepended(base)
    class << base
      prepend ClassMethods
    end  
  end  
end

Note that Extensions itself could be either prepended or included in Foo. The important part is prepending ClassMethods.

Answer 2

A simpler version:

module Extensions
  def bar
    'Extended Bar!'
  end  
end

Foo.singleton_class.prepend Extensions
