PublishSubscribe

Simple Publish/Subscribe pattern for ruby objects. It is like ruby's Observable module, but uses channels.

Adding subscriptions is not thread-safe, but if anyone wants this just open an issue and I'll add it.

It adds a public message subscribe, and two private methods, publish and subscriptions, and an instance variable, @_subscriptions, to classes that mix in this module.

Installation

Add this line to your application's Gemfile:

gem 'publish_subscribe'

And then execute:

$ bundle

Or install it yourself as:

$ gem install publish_subscribe

Usage

class Publisher
  include PublishSubscribe

  def publish_message
    publish :channel, :argument
  end
end

publisher = Publisher.new

publisher.subscribe :channel do |argument|
  puts argument
end

publisher.publish_message
# :argument
