This bundle integrates the [WildcardEventDispatcher](https://github.com/jmikola/WildcardEventDispatcher) library with Symfony and allows event listeners to be assigned using a wildcard pattern inspired by AMQP topic exchanges.

Symfony's event dispatcher component and the framework's existing convention for event names (dot-separated words) is already quite similar to AMQP message routing keys. This bundle is intended to be used sparingly, where wildcards may replace verbose configuration for central listeners, such as an activity logging service.

Some background info for this bundle may be found on the [symfony-devs](https://groups.google.com/d/topic/symfony-devs/GWeOTMfKg9s/discussion)mailing list.

Compatibility
-------------

[](#compatibility)

This bundle requires Symfony 2.3 or above.

Configuration
-------------

[](#configuration)

There are no configuration options. Symfony will load the bundle's dependency injection extension automatically.

The extension will create a service that [composes](http://en.wikipedia.org/wiki/Object_composition) the existing `event_dispatcher` service and assumes its service ID. Depending on whether debug mode is enabled, this bundle may wrap an instance of FrameworkBundle's `ContainerAwareEventDispatcher` or `TraceableEventDispatcher` class.

Listening on Wildcard Event Patterns
------------------------------------

[](#listening-on-wildcard-event-patterns)

This bundle enables you to use the single-word `*` and multi-word `#` wildcards when assigning event listeners. The wildcard operators are described in greater detail in the documentation for [WildcardEventDispatcher](https://github.com/jmikola/WildcardEventDispatcher).

### Single-word Wildcard

[](#single-word-wildcard)

Consider the scenario where the `acme.listener` service is currently listening on multiple `core` events:

```

```

You could refactor the above configuration to use the single-word `*` wildcard:

```

```

This listener will now observe all events starting with `core.` and followed by another word. An event named `core` would also be matched by this pattern.

### Multi-word Wildcard

[](#multi-word-wildcard)

Suppose there was an event in your application named `core.foo.bar`. The aforementioned `core.*` pattern would not match this event. You could use:

```

```

This syntax would match `core.foo` and `core.foo.bar`, but `core` would no longer be matched (assuming there was such an event); however, the multi-word `#` wildcard would allow all of these event names to be matched:

```

```

The `#` wildcard could also be used to listen to *all* events in the application:

```

```
