Module: Instantise

Defined in:
lib/more/facets/instantise.rb

Overview

Instantise

Instantise converts a module’s class methods into instance methods such that the first parameter is passed self at the instance level. This promotes DRY programming when wishing to offer both an inheritable and a module callable procedure.

Usage

module MyModule
  extend Instantise

  def self.jumble( obj, arg )
    obj + arg
  end
end

class String
  include MyModule
end

MyModule.jumble( "Try", "Me" )  #=> "TryMe"

"Try".jumble( "Me" )            #=> 'TryMe'
