sin_refinements

This gem enables Proc level refinements forcibly.

But it is too slow!! Please don't use in production.

sin means that this gem uses very sinned way (eval, AST, instance_exec). And sin (真) means True in Japanese.

Installation

Add this line to your application's Gemfile:

gem 'sin_refinements'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sin_refinements

Usage

module ExtMod
  refine String do
    def bang
      "#{self}!!"
    end
  end
end

  expect("foo".bang).to eq("foo!!")
end
