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 an wob instance.
tail -f /tmp/wobpipe | wob
Set up your environment so that after updating audio volume, backlight intensity, or whatever, to a new value like 43, it writes that value into the pipe:
echo 43 > /tmp/wobpipe
Adapt this use-case to your workflow (scripts, callbacks, or keybindings handled by the window manager).
See man page for styling and positioning options.
Add these lines to your Sway config file:
exec mkfifo $SWAYSOCK.wob && tail -f $SWAYSOCK.wob | wob
Volume using alsa:
bindsym XF86AudioRaiseVolume exec amixer sset Master 5%+ | sed -En 's/.*\[([0-9]+)%\].*/\1/p' | head -1 > $SWAYSOCK.wob
bindsym XF86AudioLowerVolume exec amixer sset Master 5%- | sed -En 's/.*\[([0-9]+)%\].*/\1/p' | head -1 > $SWAYSOCK.wob
bindsym XF86AudioMute exec amixer sset Master toggle | sed -En '/\[on\]/ s/.*\[([0-9]+)%\].*/\1/ p; /\[off\]/ s/.*/0/p' | head -1 > $SWAYSOCK.wob
Volume using pulse audio:
bindsym XF86AudioRaiseVolume exec pamixer -ui 2 && pamixer --get-volume > $SWAYSOCK.wob
bindsym XF86AudioLowerVolume exec pamixer -ud 2 && pamixer --get-volume > $SWAYSOCK.wob
bindsym XF86AudioMute exec pamixer --toggle-mute && ( pamixer --get-mute && echo 0 > $SWAYSOCK.wob ) || pamixer --get-volume > $SWAYSOCK.wob
Brightness using haikarainen/light:
bindsym XF86MonBrightnessUp exec light -A 5 && light -G | cut -d'.' -f1 > $SWAYSOCK.wob
bindsym XF86MonBrightnessDown exec light -U 5 && light -G | cut -d'.' -f1 > $SWAYSOCK.wob
