Hello,
I've done a first version of keyboard_layout. Find a patch attached, or
check the branch:
bzr.savannah.gnu.org/srv/bzr/grub/people/cpina/keyboard_layouts
I've tested only in at_keyboard. Using something like:
insmod at_keyboard
terminal_input at_keyboard
insmod keyboard_layouts
set keymaps_dir=/boot/grub/layouts
load_keyboard es
and before I generate the file called "es" and copied into
/boot/grub/layouts using grub-mklayout es
How could grub-mkinstall (00_header.in) know the current keyboard in the
system? I wold tweak 00_header.in to generate the keymap file and setup
it.
Comments about the current patch are welcomed, I would change it on next
days.
Some days ago I read:
"There are 2 hard problems in computer science: cache invalidation,
naming things, and off-by-1 errors."
Don't hesitate to tell me how would you rename some things, I'll do.
I'm not happy with the name of some variables/functions but I cannot
think about it today :-)
Cheers,
--
