beeep provides a cross-platform library for sending desktop notifications, alerts and beeps.

Installation

go get -u github.com/gen2brain/beeep

Examples

err := beeep.Beep(beeep.DefaultFreq, beeep.DefaultDuration)
if err != nil {
    panic(err)
}

err := beeep.Notify("Title", "Message body", "assets/information.png")
if err != nil {
    panic(err)
}

err := beeep.Alert("Title", "Message body", "assets/warning.png")
if err != nil {
    panic(err)
}

macOS

For icons to show up when using Alert() or Notify(), you will need to bundle your application with a app icon.

Variables

var (

	DefaultFreq = 440.0
	// DefaultDuration - duration in milliseconds
	DefaultDuration = 200

Functions

func Alert

func Alert(title, message, appIcon string) error

Alert displays a desktop notification and plays a beep.

Example

Alert("Title", "MessageBody", "assets/warning.png")

func Beep

func Beep(freq float64, duration int) error

Beep beeps the PC speaker (https://en.wikipedia.org/wiki/PC_speaker).

On Linux it needs permission to access `/dev/tty0` or `/dev/input/by-path/platform-pcspkr-event-spkr` files for writing, and `pcspkr` module must be loaded. User must be in correct groups, usually `input` and/or `tty`.

If it can not open device files, it will fallback to sending Bell character (https://en.wikipedia.org/wiki/Bell_character). For bell character in X11 terminals you can enable bell with `xset b on`. For console check `setterm` and `--blength` or `--bfreq` options.

On macOS this just sends bell character. Enable `Audible bell` in Terminal --> Preferences --> Settings --> Advanced.

On Windows it uses Beep function via syscall.

On Web it plays hard coded beep sound.

Example

Beep(DefaultFreq, DefaultDuration)

func Notify

func Notify(title, message, appIcon string) error

Notify sends desktop notification.

On Linux it tries to send notification via D-Bus and it will fallback to `notify-send` binary.

Example

Notify("Title", "MessageBody", "assets/information.png")
