https://github.com/libratbag/libratbag https://github.com/libratbag/libratbag It looks like libratbag is a CLI only back end that does all of the heavy lifting and then abstracts everything into an API (which Piper uses). This is actually pretty nice, as it allows any other desktop environment to use libratbag and then put their own GUI overtop of it (I do the same thing with a couple of apps).
