macos: add keyboard support

[kiwiz]

keycode is doing all the heavy lifting here.

I encountered some odd behaviour with Caps lock (which I've mapped to Control) getting stuck, but keys appear to be translated properly otherwise.

Awesome work! I didn't know about this crate.

It seems to work for me without issues. The only thing that does not work is repeating keys, it seems.

You could take some inspiration from

lan-mouse/src/backend/consumer/windows.rs

Line 91 in 8084b52

async fn spawn_repeat_task(&mut self, key: u32) {

but that may as well be a new PR.

Rust format is complaining but other than that, lgtm!

Pushed up my attempt to integrate the key repeating logic. I tried turning key_event into a method, but it might be simpler to just event_source and to pass it into key_event in the event handler and the timer?

That should do it! I'm new to Rust so feedback welcome.

That should do it! I'm new to Rust so feedback welcome.

Thank you, looking good!
Aren't we all new to Rust?

I fixed one clippy complaint and updated the README, hope you don't mind :)
