Signals

A light weight publish / subscribe. It is similar to how the gem Wisper works but without extra functionality. This library assumes nothing and concurrency is not a priortiy.

Installation

gem 'signals'

Usage

require 'signals'

class Coach
  include Signals::Publisher

  def initialize(name)
    @name = name
