Replied to Event Listeners For Extensibility?
As I said, this is very useful if you build a package and want to enable the developer to extend your code. Because you create an injection point and others can add data there.
It is often used in Symfony, e.g. here https://symfony.com/doc/current/form/dynamic_form_modification.html#adding-an-event-subscriber-to-a-form-class
Do you have an idea how I could do that without events? Overriding the service provider of a package would be a possibility, but it's less convenient imo.
Started a new Conversation Event Listeners For Extensibility?
I am working on a Laravel package which registers macros to a collection. Now I would like to make it extendable, so developers can add custom macros, too.
I know from Symfony that you can do that using events. Example:
// dispatching the event: $event = new MyEvent($myData); $this->eventDispatcher->dispatch($event); echo $event->getData();
// event listener / subscriber: $data = $event->getData(); $data = 'new item'; // possibility to change the data, e.g. append items $event->setData($data);
With this pattern, anyone can create an event listener and add items to the event's data variable.
But I'm not sure if this is possible with Laravel. I don't think you can modify the original event object like in Symfony.
Any ideas if this is possible or other possibilities to do that?
