Keymap file ignored in XWayland windows (Macbook host / Linux client)

[idest]

I created a xkb keycodes file to translate from Mac to Linux and it works fine in native wayland windows, but the file is ignored in XWayland windows.

In swaywm/sway#5461 someone suggested that the keymap might be ignored by XWayland if there's errors in the keycodes file, so I ran xkbcomp -xkb -I$HOME/.xkb/ ~/.config/waynergy/xkb_keymap to check and I got the following error and warning:

Error:            Illegal keycode 1 (must be in the range 8-255 inclusive)
                  Value of "minimum" not changed
Warning:          Unsupported maximum keycode 1024, clipping.
                  X11 cannot support keycodes above 255.
Keycodes above 1 (e.g. <AC01>) are not supported by X and are ignored

So the problem is that Mac sends keycodes in a range starting with 1, and X needs the range to start at 8. I think the only way to get this working would be for waynergy to somehow parse the keycodes coming from a Mac by adding 7 to them. This makes sense to me because the file included in /usr/share/X11/xkb/keycodes/macintosh handles it this way, where <AC01> starts with 8 and it goes up from there in the same order as the keycodes file I derived from trial and error.

Here's the contents of ~/.config/waynergy/xkb_keymap:

xkb_keymap {
	xkb_keycodes  { include "macbook+aliases(qwerty)"	};
	xkb_types     { include "complete"	};
	xkb_compat    { include "complete"	};
	xkb_symbols   { include "pc+us+inet(evdev)"	};
	xkb_geometry  { include "pc(pc105)"	};
};

and the contents of ~/.xkb/keycodes/macbook (derived from trial and error):

#5 should make this possible, does it improve the Xwayland situation on your end?

@r-c-f works perfectly, thank you!

No problem, glad it works
