Currently, the bottom border on workspace buttons eats into the box size
and causes the text to sit higher than in other modules. This is ugly
when there are other modules (like the window title) right next to the
workspace module. To fix the issue, create the bottom border using an
inset box-shadow, which doesn't affect the box's content sizing.
In the default style.css many modules (clock, battery, cpu, ...) get horizontal padding, but mpd module does not. This commit adds mpd to the list of modules that get the padding.
add a systemd --user unit/service file, so that one can run waybar as a
--user systemd service. when the service is enabled, Waybar will start
when the wayland-session.target is started.
this feature is automatically enabled if systemd is found, but can be disabled
with -Dsystemd=disabled
Because of CSS specificity rules, the `#custom-media` style will always override the `custom-spotify` and `custom-vlc` styles, so the background of the media element is always green rather than sometimes orange when VLC is running. I added `#custom-media` in front of each of the class selectors to increase their specificity so they take precedence.
Because `mpd_song_get_tag` from libmpdclient can return NULL, verify the
value of tag is valid. Otherwise, set a default string of "N/A". Also
adds configuration to specify what this default string should be.
