README.md

Allows you to use refine in older Ruby versions. It will simply fall back to prepend if available, to include otherwise (read: you will still pollute global scope).

Installation

gem install refine

Example

require 'refine' if RUBY_VERSION < '2.0'

module PassiveSupport
  refine String do
    def underscore
      # ...
    end

    def camel_case
      # ...
    end
  end

  refine Module do
    def parent
      # ...
    end
  end
end

class MyFancyApp
  using PassiveSupport
end
