Support custom script execution on clicking on a notification

[cmihail]

Issue description

I have a custom Waybar module that displays notifications count via dunstctl and on click it pops the latest notification from history. Whenever a new notification is received a custom script is executed to send a signal to Waybar to update the notification count.

But the problem is that dunst doesn't have any proper custom script execution on clicking on a notification (i.e. closing it). For normal notifications, I use the following code to send a signal to waybar for notifications whenever a notification is closed:

#!/bin/bash
dbus-monitor --profile "interface='org.freedesktop.Notifications'" | \
  awk '/NotificationClosed/ { system("$HOME/.config/waybar/scripts/update_notifications_signal.sh") }'

While this works for normal notifications, it doesn't work for notifications retrieved from history as those do not emit a DBUS event (see #1352).

Though I think that the proper solution here is not to finish #1352, but to be able to execute a custom script on clicking on a notification similarly to the following when receiving a notification:

[script_waybar_signal]
  summary = "*"
  script = $HOME/.config/waybar/scripts/update_notifications_signal.sh

Installation info

• Version:

$ dunst -v
Dunst - A customizable and lightweight notification-daemon 1.11.0

• Install type: package
• Window manager / Desktop environment: Hyprland
• Distro: Fedora 40

Minimal dunstrc

[global]
  follow = mouse
  origin = top-center
  idle_threshold = 10s
  mouse_left_click = "do_action, close_current"
  mouse_right_click = "close_current"
  mouse_middle_click = "close_all"
  icon_path = "/usr/share/icons/AdwaitaLegacy/48x48/legacy/"
  icon_theme = AdwaitaLegacy

[script_waybar_signal]
  summary = "*"
  script = $HOME/.config/waybar/scripts/update_notifications_signal.sh

[ignore_volume_change]
  stack_tag = "change_volume"
  history_ignore = yes
  timeout = 1s

[ignore_brightness_change]
  stack_tag = "change_brightness"
  history_ignore = yes
  timeout = 1s

[skip_google_meet_notifications]
  body = "*meet.google.com*"
  skip_display = yes
  history_ignore = yes

---

Note: I'd be interested in implementing this feature myself if that is fine.

Hello, sorry for the late reply. This is a great idea and probably will be added some time in the future.

Probably it could be accomplished by adding a run_script option to

mouse_[left/middle/right]_click (values: [none/do_action/close_current/close_all/context/context_all])

I'm not sure about how to specify the script though. Any suggestion is appreciated 👍🏻
