# event

Go event library to subscribe and fire events used to decouple the event

source and sink in complex or add-on based systems.

```go

// Custom event type

type MyEvent struct {

    Message string

}

// Create a new event manager.

mgr := New()

// Subscribe to the event.

Subscribe(mgr, 0, func(e *MyEvent) {

    // Handle the event.

    fmt.Println("handler A received event:", e.Message)

})

// Subscribe to the event higher priority.

Subscribe(mgr, 1, func(e *MyEvent) {

    // Handle the event.

    fmt.Println("handler B received event:", e.Message)

    e.Message = "hello gophers"

})

unsubscribe := Subscribe(mgr, 0, func(e *MyEvent) {

    // Handle the event.

    fmt.Println("handler C received event:", e.Message)

})

// Unsubscribe from the event if you want to or ignore and never call it.

unsubscribe()

// Fire the event.

mgr.Fire(&MyEvent{Message: "hello world"})

```
