Write custom broadcasters

When an event is broadcast to a listener it is done so via an adapter which can choose how to broadcast that event. The default broadcaster simply does listener.public_send(event_name, *args).

Example broadcaster gems include LoggerBroadcaster, Wisper::Celluloid and Wisper::Sidekiq

• First create a new gem:

bundle gem wisper-thingy_broadcaster

• Add your broadcaster class which has a method broadcast.

module Wisper
  module Thingy
    class ThingyBroadcaster  
      def broadcast(subscriber, publisher, event, *args)
        # ...
      end
    end
  end
end

That's it.

You can then use your broadcaster as such:

Wisper.configure do |config|
  config.broadcaster(:thingy, Thingy::ThingyBroadcaster.new)
end

Wisper.subscribe(MyListener.new, broadcaster: :thingy)

You might also want to have the broadcaster self register itself with Wisper.configuration, see existing broadcasters for an example.
