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 goes:

I know that I can include classmethods by extending the module ClassMethods and including it via the Module#include hook. But can I do the same with prepend? Here is my example:

class Foo:

class Foo   def self.bar     'Base Bar!'   end end  

class Extensions:

module Extensions   module ClassMethods     def bar       'Extended Bar!'     end   end    def self.prepended(base)     base.extend(ClassMethods)   end end # prepend the extension  Foo.send(:prepend, Extensions) 

class FooE:

require './Foo'  class FooE < Foo end 

and a simple startscript:

require 'pry' require './FooE' require './Extensions'  puts FooE.bar 

When I start the script I don't get Extended Bar! like I expect but rather Base Bar!. What do I need to change in order to work properly?

Answer 1

A simpler version:

module Extensions   def bar     'Extended Bar!'   end   end  Foo.singleton_class.prepend Extensions
