Ruby: module, require and include

Question

I\'m trying to use Ruby modules (mixins).

I have test.rb:

#!/usr/bin/env ruby
require_relative \'lib/mymodule\'

class MyApp
  include MyModule
  sel         


        

Answer 1

In short: you need to extend instead of include the module.

class MyApp
  extend MyModule
  self.hallo
end

include provides instance methods for the class that mixes it in.

extend provides class methods for the class that mixes it in.
