Go event library to subscribe and fire events used to decouple the event source and sink in complex or add-on based systems.
// 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"})
