I am new to Ruby and have been following a couple of tutorials to learn more about it.
Here’s the baseline code. I have a Publisher and a class, Checkout, that
includes this Publisher.
module MyPublisher def subscribe(subscribers) @subscribers += subscribers end def publish(event, *payload) @subscribers ||=  @subscribers.each do |subscriber| subscriber.public_send(event.to_sym, *payload) if subscriber.respond_to?(event) end end end class Checkout include MyPublisher end checkout = Checkout.new items =  checkout.subscribe "event-item-added" do |data| # How can I get here inside this listener? So that "item << data" is executed? puts "checkout received an item!" items << data end queue.publish "event-item-added", 52 queue.publish "event-item-added", 90 queue.publish "event-item-added", 16
My question is: how to get the data that is published inside the
...do |data| block/listener? (I also put a comment to show where I am talking about).
