i3-notifier 0.21

A notification daemon for i3

i3 Notification Manager (Requires a recent version of rofi)

This is a notification manager for i3 desktop environment inspired by Rofication. Like Rofication, it implements the Gnome Desktop Notifications Standard standard.

Also see the companion py3status module py3-notifier.

Differences from Rofication

• Notifications are stored in a tree structure, where they can be grouped by, for example, the application that is sending the notification and the subject. This is highly configurable. (No docs at the moment, but see the examples/i3_notifier_config.py; also see the comments in i3notifier/config.py)
• Allows bulk deletion of notifications in a category.
• Implements "default" action.
• Shows icons.
• Does not use sockets, rather adds new dbus methods to show the notifications and get the count of notifications.
• Code is modular, should be straight forward to use another GUI rather than Rofi; or another data structure rather than tree structure.

Usage

To install (also see the requirements.txt)

pip install i3-notifier

Make sure you are not running any other notification daemon (if you are running dunst for example, kill it with killall dunst). Then start i3-notifier. You might want to make sure i3-notifier and its companion script switch-to-urgent.py are in the $PATH. You can confirm it is running by

dbus-send --session --print-reply --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.GetServerInformation

Then to launch GUI; bind this to a shortcut

dbus-send --session --print-reply --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.ShowNotifications

Keybindings

Key	Action
j, Down, Tab or Ctrl-N	Choose next
k, Up or Ctrl-P	Choose previous
Enter, Space or Left Click	Expand if group; execute action if singleton
Shift-Enter	Execute action
Esc, Ctrl+[ or Backspace	One level up or exit from top level
`, Ctrl+Backspace or Shift-Backspace	Exit from any level.

Ctrl+Delete, Shift+Delete	Delete single notification

To get notification count & urgency

dbus-send --session --print-reply=literal --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.ShowNotificationCount

One can use this with i3blocks to show notifications in the bar or even better switch to py3status and install py3-notifier.

command = "(dbus-send --session --print-reply=literal --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.ShowNotificationCount 2>/dev/null || ($HOME/.local/bin/i3-notifier && echo '? ? ?'))|tr -s ' '|cut -d' ' -f 3"
