[Feature Request] Swap alt/meta

[kiwiz]

Specifically, I'd like to swap the alt and meta keys between a specific client/server pair. A more general key remapping feature would be interesting too, but I don't know if that would be considered in scope for this project.

+1 for this - these are mysteriously swapped on my MacBook using the mouse plugged into my Fedora 43 machine (running Hyprland from the sdegler copr). The other thing that would be really useful is scroll direction swapping for the same reason. These could be toggles imho. For anyone coming to this looking for a workaround, I am using a bash script with hyprctl to do this:

#!/usr/bin/env bash

IS_LINUX=true

set_linux() {
  if [ "$IS_LINUX" = true ]; then
    return
  fi
  hyprctl keyword device[mouse-device-id]:natural_scroll false
  hyprctl keyword device[keyboard-device-id]:kb_options ""
  IS_LINUX=true
}

set_mac() {
  if [ "$IS_LINUX" = false ]; then
    return
  fi
  hyprctl keyword device[mouse-device-id]:natural_scroll true
  hyprctl keyword device[keyboard-device-id]:kb_options "altwin:swap_alt_win"
  IS_LINUX=false
}

while true; do
  CURRENT_X=$(hyprctl cursorpos | grep -o '^[0-9]\+')
  if [ "$CURRENT_X" -eq "0" ]; then
    set_mac
  else
    set_linux
  fi
  sleep 0.5
done

@alex-moon see #347, which coincidentally would be a good place in the config to put this as well.
