WildcardEventDispatcher
=======================

[](#wildcardeventdispatcher)

This library implements an event dispatcher, based on [Symfony's interface](https://github.com/symfony/EventDispatcher), with wildcard syntax inspired by AMQP topic exchanges. Listeners may be bound to a wildcard pattern and be notified if a dispatched event's name matches that pattern. Literal event name matching is still supported.

Note: the wildcard syntax used by this library is not compatible with the [simpler event dispatching](https://symfony.com/blog/new-in-symfony-4-3-simpler-event-dispatching) introduced in Symfony 4.3, which uses the FQCN of the event in lieu of a custom string (e.g. `core.request`).

If you are interested in using this library in a Symfony project, you may also want to take a look at the corresponding [bundle](https://github.com/jmikola/JmikolaWildcardEventDispatcherBundle).

Installation
------------

[](#installation)
