Add new API to deal with xkb_state objects, including
xkb_state_update_key, which runs the XKB action machinery internally to
calculate what exactly happens to the state when a given key is pressed
or released.
The canonical way to deal with keys is now:
struct xkb_state *state = xkb_state_new(xkb);
xkb_keysym_t *syms;
int num_syms;
xkb_state_update_key(state, key, is_down);
num_syms = xkb_key_get_syms(state, key, &syms);
More state handling API, including a way to get at or ignore preserved
modifiers, is on its way.

Previously, we would clear out the real modmask when updating the

On many layouts, the following error appears:
Internal error: Could not resolve keysym 10005b0
(Which is like the trademark of libxkbcommon now, and makes
unicode-heavy symbol files pretty useless).
This occurs when a keysym string (in this case, 10005b0) is passed to
xkb_string_to_keysym, but cannot be resolved.
This in turn happens because the parser passes on hexadecimal keysym
strings without the leading "0x", thus leaving the resolving function
without a way to disambiguate it as a number.
Therefore, make sure to pass on the "0x". The file symbols.c in xkbcomp
project does the same; it probably got lost in translation.

The listing code in xkbcomp had been setup to allocate a set of buffers
with file paths and then later parse through them to find which maps were
needed.
All the allocation (with the additional allocation for the components
list) was making it really slow, so this patch makes everything simpler
by just generating the components list as we walk the directory tree.
In xkbcomp, the listing code printed out the xkb files to stdout and the
caller would parse the output. Here, we can just generate a
XkbComponentListPtr and pass it back.
This should be a series of smaller commits, but there was no clean way to
do it since it's basically a complete rewrite except for the core map
matching logic.
A lot of code used for special printing modes in xkbcomp has been
shedded. Callers can massage the output as they please.
This reverts commit c4c9e36fbf. It turns
out that the listing code is used to support the X_kbListComponents
request (via XkbListComponents).
This will have to be refactored into some reasonable interface instead
of the current usage where the server reads xkbcomp stdout. Gross.
Instead of hardcoding the XKB base directory when searching for rules in
the xkbcomp code, we can extend the xkbpath API to cover rules and reuse
it. That will make it more convenient if it's ever exposed so people can
set their XKB search paths in a reasonable way.
We need to support generating a keyboard description from a keymap file
because there are just some cases where RMLVO or ktcsg is not enough.
The map choosing logic has been refactored into its own function and now
supports choosing a named or default keymap.
The noble intention was to expose all the new API and new generic types
in the split out kbproto headers through XKBcommon.h. It turns out that
would be a massive amount of work in the server. Someday, but first just
wedging in XkbCompileKeymap* would be good.
Most of the API is in new internal xkb*.h headers. In order to allow the
XKBcommon.h header to be used from the server, we can't pull in other
headers from kbproto since the server has its own copies. However, types
that are different (XkbDescRec, XkbAction) still have Xkbc equivalents
here, and I think they should be used in the server.
Some of the XkbAction types are defined differently in the server, so we
add those to XKBcommon.h and use them here like XkbcDescPtr. We'll have
to deal with the impedance mismatch on the client side later.
XkbcRF_GetComponents was returning an error but leaving the generated
components alone. This ensures that the broken XkbComponentNamesPtr is
freed and the error is passed up to the caller.
Instead of requiring the user to call XkbInitIncludePath() and
XkbAddDefaultDirectoriesToPath(), all the path entry points now implicitly
initialize the path. When initializing, the default directories are added
so it's useful.
This provides normal operation without exposing the xkbpath API. That
might happen later to allow apps to edit the XKB search path.
XkbcCompileKeymapFromRules can be used to generate a XkbDescPtr from XKB
rules instead of using components. The previous XkbcCompileKeymap has
been renamed to XkbcCompileKeymapFromComponents.
Copy over the Xkb_RF* rules parsing functions from xkbfile's maprules.c.
Eventually, this will be tied into xkbcomp's path searching utilities so
you don't need to supply a full path to the rules file. Also, it this
should eventually incorporate the server's RMLVOSet.
Finally, we can generate a XkbcDescPtr from a XkbComponentNamesPtr. This
involves turning the components into a parsed XKB file and then passing
it into the compiler. This first conversion needs more error handling.
xkbcomp was using Xlib's XConvertCase to check upper/lowercase. That's a
lot of code, so hopefully the xkbfile macros using _XkbKSCheckCase are
good enough. This also required that <X11/keysym.h> is included to get
all the XK_* definitions.
Added common variants of XkbComputeEffectiveMap, XkbInitCanonicalKeyTypes
and all their needed functions. A couple functions that were in alloc.c
moved to malloc.c to mirror the libX11 sources better.
Original code in
libX11/src/xkb/XKBMalloc.c
libX11/src/xkb/XKBMisc.c
libX11/src/xkb/XKB.c
This should cover all the usage in xkbcomp. The format arguments were
dropped except for the special case of XkbModMaskText, which needs to
write in XkbCFile format in HandleVModDef. This was just changed to a
Bool to avoid the need for the macros in XKBfile.h.
The function prefixes have been renamed to be unique from xkbfile.
The only real usage was in the frontend to generate a .xkm file. The
rest of the code just operated on the attached XkbDescPtr. Note that
here we've replaced the usage of the defined field in CompileKeymap with
the equivalent field in a XkbcDescPtr.
A copy of the xkbcomp sources (except the frontend) have been copied in
to provide a means to compile a XkbDescPtr. This definitely doesn't
build or do the right thing yet.
This avoids the BUILT_SOURCES weirdness and forcing the build into the
makekeys subdirectory. Added a new make variable KS_HEADERS that lists
all the keysym headers we're going to parse.
Some coding style nits were cleaned up. Additionally, most of the
functions have been collapsed from the libxkbfile version where there's
distinction with the Xlib atom functions when Display was set. Finally,
the InitAtoms function tests whether the table has already been created
by testing the pointer rather than using a static int.
Mostly tab-to-space conversion plus a few style nits. Dropped the
register keywords as I'm pretty sure modern compilers can be trusted to
do the right thing.
Following the kbproto convention, the headers will be named XKBcommon.h
and XKBcommonint.h. Furthermore, they'll be installed in X11/extensions
directory with the rest of the XKB headers.
Copies the code to initialize and destroy an XkbDescRec from libX11. The
original code is in
libX11/src/xkb/XKBAlloc.c
libX11/src/xkb/XKBGAlloc.c
libX11/src/xkb/XKBMAlloc.c
These are used throughout the XKB code, but are defined in XKBsrv.h,
which we'd like to avoid. Internal definitions for True/False have also
been added since they're in Xlib.h
Mostly tab-to-space conversion plus a few style nits. Dropped the
register keywords as I'm pretty sure modern compilers can be trusted to
do the right thing.
Add the xkbcommon implementations of XKeysymToString and XStringToKeysym.
These symbols have the namespace prefix of Xkbc and are declared in
X11/XkbCommon.h.
The implementation is taken directly from Xlib, but does not include the
XKeysymDB parsing and hashing yet (if it ever will). A couple type
conversions were needed to keep from using Xlib.h. See original files:
libX11/src/KeysymStr.c
libX11/src/StrKeysym.c
The makekeys utility is used to generate the keysym hash tables during
the build. We try to detect a build machine native compiler so the
tables can be generated when cross compiling.
