evdev but tiny and for keyboard events only.
Why?
Because a while back I used golang-evdev to make typeworm, and since then I've been wanting to basically make golang-evdev myself.
What?
This is a minimal evdev-like module, but it only works for keyboard devices. You are probably better off using some other more robust implementation, even if deprecated. This was made just for fun.
How?
Be on Linux. Install the module, import and use it in your program, then compile and run with sudo. Make sure you be on Linux first.
func main() {
keyboard, err := kyev.GetKeyboard("keyboard", "usb")
if err != nil {
panic(err)
}
for {
events, err := keyboard.GetEvents()
if err != nil {
panic(err)
}
for _, event := range events {
// handle events
}
}
}
Why run with sudo?
How else am I going to recursively force-delete all your shit?
Nah but for real, device input events are read from /dev/input/event* files, which your every-day user generally doesn't have read access to.
