Running on my Fedora KDE machine right now. Also includes a CLI so you could wrap your own widget
I still need to figure out publishing, doing this in between work meetings.
I packaged it for Arch Linux AUR: https://aur.archlinux.org/packages/whatcable-linux

Thanks to the previous implementers/clauders.. I don't take any credits.
Is this the human centipede of programming?
