Modules and foo

Ruby
1

I have some questions about some things that i don’t understand…
here is some code fragments

I have two questions.

One… is there a better way to inherit between modules
that i don’t know about?

Two… why, when a method is called in module Bar does the Module
InstanceMethods in Bar not get included?

module Blah
def self.append_features(base)
super
base.extend ClassMethods
end
module InstanceMethods
def visible

       end
  end
  module ClassMethods

         def _do_other

	class_eval <<-EOV
	  include InstanceMethods
	EOV

    end

         def do_blah
	"blah"
         end
  end

end

module Bar
def self.append_features(base)
super
base.extend ClassMethod

This is ugly

How do i avoid this?

       base.extend Blah::ClassMethods
  end
  module InstanceMethods
       def hidden

       end
  end
  module ClassMethods
	def do_bar
		do_blah
		 #
		 #
		 # When i do this , i don't get the InstanceMethods of Bar, just Blah
		 #
		_do_other
	end
  end

end

Do you mean “class InstanceMethods”? Modules are collections, often of
classes.

I’m following a pattern that Rails uses for the “Acts As” code.

I don’t want to muddle with the inheritance tree, i just want to mix-
in methods.
