4 years agocontext: move ~/.xkb to before XKB_CONFIG_ROOT in the default include path
Ran Benita [Thu, 3 Oct 2019 14:27:00 +0000 (17:27 +0300)]
context: move ~/.xkb to before XKB_CONFIG_ROOT in the default include path

Previously, the default include path was XKB_CONFIG_ROOT:~/.xkb.

The ~/.xkb include path is intended to allow the local user to customize
their keymaps without having to modify system paths.

But usually, the user only wants to customize specific parts. When
XKB_CONFIG_ROOT is first, the user can only customize through the "entry
point" (the RMLVO). When ~/.xkb is first, the user can drop in a file
and it will override the system one.

The impetus for this change is the rules file. "evdev" is hard-coded
everywhere, so it not often not possible to change to something else.
And the rules files determines how the rest of the RMLVO is interpreted.
So, to enable customization, we have these options:

A: System includes user.
B: User includes system.
C: Library goes over both in one or the other order.

Option A is problematic due to backward compatibility and is also
unnatural.

Option B gives the user control and is backward compatible, so that's
what we choose. This is also how Compose files are handled, and that
seems to work fine in the wild.

Option C is actually less flexible than B, and more complicated.

(The rules file format doesn't have an include statement yet, but it's
planned).
