How to modify/add compose (multi key) shortcuts and keyboard layout with wayland?

[Gregory Salvan]

Hi,
I've failed these last days to edit my keyboard layout and add compose shortcuts on a
fedora 30 (5.4.17-100.fc30.x86_64) with gnome 3.32.2 on wayland.
For keyboard layout when editing /usr/share/X11/xkb files I can replace some keys, but I
would prefer do it at user level to not have my files erased by an update.
 so I've tried ~/.xkb (and even ~/.Xmodmap) dug into /etc/ , ~/.config, and dconf and
found nothing relevant.
I've tried with and without ibus.

For compose, I've tried to edit /usr/share/X11/locales/*/Compose and also created a
~/.XCompose file and nothing happened.

Can someone explain me how can I make a user defined configuration for my keyboard layout
and for compose keys please ?

The last time I checked into this (middle of 2019), this was not
possible with wayland.  To run a custom keymap (something other than
qwerty, dvorak, or colemak), it is necessary to use X.  I hope someone
responds that it is now possible.

Though you could do it the way you suggested, and replace one of those
covered key mappings with your custom keymapping.  They rarely change,
so you would probably not have to do any repair, except after upgrade
to a newer version of Fedora.

Thanks for the thoughts.  I can replace qwerty with my custom
keymap, since I never use it, and have access to wayland.  I never
thought of doing that until you mentioned it.  And even better, when
there are problems, because the recovery modes all default to qwerty, I
would instead have access to my custom keymap and no longer have to
hunt and peck.
