Calling a method of a Ruby Singleton without the reference of 'instance'

Question

I would like to call a method of a Singleton Object without the reference to its instance

SingletonKlass.my_method

instead of

S         


        

Answer 1

Instead of SingletonKlass, I'll use the name UrlHelper as a more concrete example.

require 'singleton'    

class UrlHelperSingleton
  include Singleton

  def my_method
     ...
  end
end

UrlHelper = UrlHelperSingleton.instance

# then elsewhere
UrlHelper.my_method
