Go-Notification

Go package for sending Desktop Notifications and handling NotificationClosed and ActionInvoked signals.

For more information see the documentation.

Handler functions

The functions for handling signals will be executed as goroutines.

Example

An application monitors some processes and informs the user with a desktop notification when one has finished. The user can click on an action button in the notification to open a page in a web browser to see more details.

package main

import (
	"fmt"

	"github.com/andreas19/go-notification/notification"
)

func openPage(proc_id int) {
	url := fmt.Sprintf("http://localhost/details&proc_id=%d", proc_id)
	// open page with the given url in a web browser
}

func notify(proc_id int, ok bool) {
	var icon, status string
	var urgency notification.Urgency
	if ok {
		icon = "icons/icon.png"
		status = "SUCCESS"
		urgency = notification.UrgencyNormal
	} else {
		icon = "icons/error.png"
		status = "ERROR"
		urgency = notification.UrgencyCritical
	}
	noti := notification.New(fmt.Sprintf("Process %d finished", proc_id), "Status: " + status)
	noti.SetIcon(icon)
	noti.SetUrgency(urgency)
	noti.AddActionHandler("details", "Details", func() {
		openPage(proc_id)
	})
	notification.Notify(noti)
}

func main() {
	err := notification.Init("Example App", "")
	if err != nil {
		panic(err)
	}
	// start monitoring processes
}

// a process has just finished and the details are stored somewhere so
// they can be retrieved for the web page
