If you're in a position to use this program[0], you're already taking the same risk by running most other programs on your machine - they also have access to your keypresses.

[0]: The only real reason you wouldn't be is if you're on a non-X Linux desktop. Wayland prevents this kind of program by design.

Fun fact, Wayland support is the most requested feature [1] and I think it's possible, although we will need to go deeper in the stack and exploit EVDEV

A nice technical writeup! The daemon approach sounds particularly promising. Have you also thought about a Wayland protocol extension? espanso is not the only program that will want total keyboard access, and it's one of the last big obstacles for a lot of X11 users.

Thanks!

> Have you also thought about a Wayland protocol extension?

I honestly didn't think about that! That might be an option, perhaps when espanso becomes more well-known in the community. Before that, it's unlikely that any change I suggest will make its way into the specification :)

That's absolutely ok! I'm also very open to feedback if you have any :)
