A notification system for tiling window managers. twmn is two things:

twmnc: command line tool to send notifications to twmnd. You can also use notify-send for a similar purpose, but twmnc is more powerful. See twmnc --help for more information.

twmnd: daemon listening to notification requests and showing them one after another. Configure it at ~/.config/twmn/twmn.conf. The file is generated the first time twmnd is launched.

Notifications are shown in a one-line bar called the notification slide. They can be navigated through and activated with shortcuts.

See twmn.conf for more information.

For Arch Linux users, twmn is on the AUR.

Otherwise you can install twmnd and twmnc manually:

1. install boost, qt and dbus if they weren't before
2. git clone https://github.com/sboli/twmn.git to get twmn
3. cd twmn/
4. qmake to generate a Makefile
5. make to compile
6. sudo make install to install twmnd and twmnc in /usr/local/bin. Make sure this folder is in your $PATH environment variable. (export PATH=$PATH:/usr/local/bin)
7. for twmnd to be always running, add it to your .xinitrc, rc.conf or else

The storage_notifier example requires dbus-python to be installed. The mpd_notifier example requires python-mpd to be installed and running.
