Question

Suppose I have a module with the methods : function1,function2,function3. I want to import function1 and function2 but not function3. Is there a way to do this in ruby?

Answer 1

Not sure if there is a clean way to just add the methods you want, but you can remove the methods that you don’t want by using undef_method.

module Foo   def function1   end    def function2   end    def function3   end end  module MiniFoo   include Foo   not_wanted_methods = Foo.instance_methods - %w(function1 function2)   not_wanted_methods.each {|m| undef_method m} end  class Whatever   include MiniFoo end
