x11: add XKB protocol keymap and state creation support

These are function to create an xkb_keymap directly from XKB requests
to the X server. This opens up the possibility for X clients to use
xcb + xcb-xkb + xkbcommon as a proper replacement for Xlib + xkbfile for
keyboard support.

The X11 support must be enabled with --enable-x11 for now.
The functions are in xkbcommon/xkbcommon-x11.h. It depends on a recent
libxcb with xkb enabled. The functions are in a new libxkbcommon-x11.so,
with a new pkg-config file, etc. so that the packages may be split, and
libxkbcommon.so itself remains dependency-free.

Why not just use the RMLVO that the server puts in the _XKB_RULES_NAMES
property? This does not account for custom keymaps, on-the-fly keymap
modifications, remote clients, etc., so is not a proper solution in
practice. Also, some servers don't even set it. Now, the client just
needs to recreate the keymap in response to a change in the server's
keymap (as Xlib clients do with XRefreshKeyboardMapping() and friends).

Ran Benita [Wed, 27 Nov 2013 11:49:13 +0000 (13:49 +0200)]
Resolve keysyms early in parser

Instead of having the parser passing strings to the AST, and
symbols/compat etc. resolving them themselves. This simplifies the code
a bit, and makes it possible to print where exactly in the file the bad
keysym originates from.

The previous lazy approach had an advantage of not needlessly resolving
keysyms from unrelated maps. However, I think reporting these errors in
*any* map is better, and the parser is also a bit smarter then old
xkbcomp and doesn't parse many useless maps. So there's no discernible
speed/memory difference with this change.

10 years agostate: apply capitalization transformation on keysyms
Ran Benita [Tue, 13 Aug 2013 15:57:43 +0000 (18:57 +0300)]
state: apply capitalization transformation on keysyms

The xkbproto spec says:
http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Interpreting_the_Lock_Modifier

    If the Lock modifier is not consumed by the symbol lookup process,
    routines that determine the symbol and string that correspond to
    an event should capitalize the result.

This was not an issue until now, because most xkeyboard-config keymaps
do not utilize this "feature", and specify the keysyms for the Lock
modifier explicitly instead. However, some keymaps do depend on it, e.g.
ch(fr) for eacute and others.

The spec goes on to describe two options for doing this transformation:
locale-sensitive and locale-insensitive. We opt for the latter; it is
less desirable but we don't want *that* headache.

Also, only xkb_state_key_get_one_sym() is changed;
xkb_state_key_get_syms() is left as-is, and always reports the
untransformed keysyms. This is for the following reasons:

- The API doesn't allow it, since we return a const pointer directly to
  the keymap keysyms table and we can't transform that.

- The transformation doesn't make sense for multiple-keysyms.

- It can be useful for an application to get the "raw" keysyms if it
  wants to (e.g. maybe it wants to do the transformation itself).

Finally, note that xkb_state_mod_index_is_consumed() does *not*
report Lock as consumed even if it was used in the transformation. This
is what Xlib does.

This definitely doesn't fall under the "hard to misuse" API rule but
it's the best we can do.

scanner: allow empty key name literals

Some keymaps actually have this, like the quartz.xkb which is tested. We
need to support these.

10 years agoxkbcomp: handle empty keymaps

xkbcomp: handle empty keymaps

We should handle empty xkb_keycode and xkb_symbol sections, since
xkbcomp handles them, and apparently XQuartz uses it. There are also
files for it in xkeyboard-config (rules=base model=empty layout=empty,
which translate to keycodes/empty and symbols/empty).
