xbps-update-polybar

View how many updates are available on Void Linux's XPBS package manager, straight from Polybar.

Installation

1. Download the files as a ZIP or clone into a temporary directory.
2. Move xbps-updates.sh to the ~/.config/polybar/ directory.
3. Make xbps-updates.sh executable by executing chmod u+x ~/.config/polybar/xbps-updates.sh.
4. Decide where you will put the module. Depending on your choice, add xbps-updates to the modules-left,modules-center or modules-right variable in your polybar config file.
5. Add the following lines to the ~/.config/polybar/config file:

[module/xbps-updates]
type = custom/script
exec = ~/.config/polybar/xbps-updates.sh
interval = 120

Left click to install updates

It's entirely possible to add a quick shortcut to install the available update(s) directly from Polybar. I use the alacritty terminal, and for this terminal it can easily be achieved by adding an additional line under the [module/xbps-updates] section as follows:

click-left = alacritty -e sudo xbps-install -Su

Please refer to the manual or wiki of your terminal emulator on the exact syntax required to implement this.
