You may manage a bar for audio volume, backlight intensity, or whatever, using a named pipe. Create a named pipe, e.g. /tmp/wobpipe, on your filesystem using.

mkfifo /tmp/wobpipe

Connect the named pipe to the standard input of a wob instance.

tail -f /tmp/wobpipe | wob

echo 43 > /tmp/wobpipe

Adapt this use-case to your workflow (scripts, callbacks, or keybindings handled by the window manager).

See wob.ini.5 for styling and positioning options.
