Yes, it works. I'm typing using the PR version right now!

It's great!

That's a cool use case, thanks for sharing it! 👍

You've probably found this already, but for reference, the input reading is done in:
https://github.com/jtroo/kanata/blob/main/src/oskbd/linux.rs

Currently, the event loop does blocking calls to fetch_events for a single device, so would need to rearchitect the input event handling to be able to handle multiple devices. It would be good to dig into evsieve's source as inspiration for how they do it.

Edit:

Browsing through evsieve's source, it uses C style code using epoll and raw file descriptors. Quite efficient, but a lot more complicated than what kanata's doing.

I've added a kanata-evsieve crate exposing the evsieve functionality as a library. Not sure yet if using it is a viable strategy, but seems like it should work out okay.

@br-lemes please test the code in the new PR at your leisure. I haven't actually tested it on multiple keyboards myself since I don't have a convenient way to do so, but I think it should work.

Config change:

  ;; If you want to read from multiple devices, separate them by `:`.
  ;; linux-dev /dev/input/<dev1>:/dev/input/<dev2>
