If the active set of modifiers doesn't match any explicit entry of the
key type, the resulting level is 0 (i.e. Level 1). Some key types don't
explicitly map Level 1, taking advantage of this fallback.
Previously, xkb_keymap_key_get_mods_for_level didn't consider this, and
only reported masks for explicit mappings. But this causes some glaring
omissions, like matching "a" in the "us" keymap returning not results.
Since every mask which isn't explicitly mapped falls back to 0, we can't
return the all. Almost always the best choice for this is the empty
mask, so return that, when applicable.

The new API is useful to implement features like auto-type and
desktop automation. Since the inputs for these features is usually
specified in terms of the symbols that need to be typed, the
implementation needs to be able to invert the keycode->keysym
transformation and produce a sequence of keycodes that can be used
to type the requested character(s).
In order to support features like auto-type and UI automation, the
relevant tools need to be able to invert the keycode->keysym->text
transformation. In order to facilitate that, a new API was added.
It allows querying the keysyms that correspond to particular Unicode
codepoints. For all practical purposes, it can be thought of as an
inverse of xkb_keysym_to_utf32().
This provides implementations of the test_enable_stdin_echo and
test_disable_stdin_echo which do not require <termios.h>, which is
not available on Windows.
Only the input/output functions from <unistd.h> options are used, so
using <io.h> when building with MSVC should be enough. The inclusion
of the header in context-priv.c does not seem to be needed (tested
on GNU/Linux) and so it is removed.

The majority use-case for extending XKB on a machine is to override one or a
few keys with custom keycodes, not to define whole layouts.
Previously, we relied on the rules file to be a single file, making it hard to
extend. libxkbcommon parses $XDG_CONFIG_HOME/xkb/ but that only works as long
as there is a rule that matches the user-specified RMLVO. This works for MLV
but not for options which don't have a wildcard defined. Users have to copy
the whole rules file and then work from there - not something easy to extend
and maintain.
This patch adds a new ! include directive to rules files that allows including
another file. The file path must be without quotes and may not start with the
literal "include". Two directives are supported, %H to $HOME and %S for the
system-installed rules directory (usually /usr/share/X11/xkb/rules).
A user would typically use a custom rules file like this:
! option = symbols
custom:foo = +custom(foo)
custom:bar = +custom(baz)
! include %S/evdev
Where the above defines the two options and then includes the system-installed
evdev rule. Since most current implementations default to loading the "evdev"
ruleset, it's best to name this $XDG_CONFIG_HOME/xkb/rules/evdev, but any
valid name is allowed.
The include functionally replaces the line with the content of the included
file which means the behavior of rules files is maintained. Specifically,
custom options must be defined before including another file because the first
match usually wins. In other words, the following ruleset will not assign
my_model as one would expect:
! include %S/evdev
! model = symbols
my_model = +custom(foo)
The default evdev ruleset has wildcards for model and those match before the
my_model is hit.
The actual resolved components need only be in one of the XKB lookup
directories, e.g. for the example above:
$ cat $XDG_CONFIG_HOME/xkb/symbols/custom
partial alphanumeric_keys
xkb_symbols "foo" {
key <TLDE> { [ VoidSymbol ] };
};
partial alphanumeric_keys
xkb_symbols "baz" {
key <AB01> { [ k, K ] };
};
This can then be loaded with the XKB option "custom:foo,custom:bar".
The use of "custom" is just as an example, there are no naming requirements
beyond avoiding already-used ones. Also note the bar/baz above - the option
names don't have to match the component names.

- a simple program to convert RMLVO commandline arguments into a keymap (and

- a python script that runs through rules/evdev.xml, and tries to compile a

we can have multiple options and it really only does one per layout(variant)
combination.

We currently use strcasecmp, which is locale-dependent. In particular,
one well-known surprise even if restricted just ASCII input is found in

https://msdn.microsoft.com/en-us/library/ms973919.aspx#stringsinnet20_topic5
We have known to avoid locale-dependent functions before, but in this
case, we forgot.
Fix it by implementing our own simple ASCII-only strcasecmp/strncasecmp.
Might have been possible to use strcasecmp_l() with the C locale, but
went the easy route.
Side advantage is that even this non-optimized version is faster than
the optimized libc one (__strcasecmp_l_sse42) since it doesn't need to
do the locale stuff. xkb_keysym_from_name(), which uses strcasecmp
heavily, becomes faster, and so for example Compose file parsing, which
uses xkb_keysym_from_name() heavily, becomes ~20% faster.

The current functions dealing with consumed modifiers use the
traditional XKB definition of consumed modifiers (see description in the
added documentation). However, for several users of the library (e.g.
GTK) this definition is unsuitable or too eager. This is exacerbated by
some less-than-ideal xkeyboard-config type definitions (CTRL+ALT seems
to cause most grief...).
So, because we
- want to enable alternative interpretations, but
- don't want to expose too much internal details, and
- want to keep things simple for all library users,
we add a high-level "mode" parameter which selects the desired
interpretation. New ones can be added as long as they make some sense.
All of the old consumed-modifiers functions keep using the traditional
("XKB") mode. I mark xkb_state_mod_mask_remove_consumed() and as
deprecated without adding a *2 variant because I don't it is very useful
(or used) in practice.
Alternative modes are added in subsequent commits (this commit only adds
a mode for the existing behavior).

The `test/data/keymaps/host.xkb` file contains a duplicate definition of
this type. On my computer (linux, xkbcomp 1.3.0, xserver 1.17.2), the
test passes as is, but if I remove the duplicate definition, the
roundtrip brings it back and the test fails. I can also reproduce it
without relation to the test, by loading `test/data/keymaps/host.xkb`
(without the duplicate) using
xkbcomp -I $(pwd)/test/data/keymaps/host.xkb $DISPLAY
and downloading it again using
xkbcomp $DISPLAY out.xkb
the duplicate is added. On Mac OS X however, the duplicate is removed
(correctly), so the test fails there.
xkbcommon itself, which was forked from xkbcomp, doesn't have this bug;
in fact, doing
./test/print-compiled-keymap -k keymaps/host.xkb
removes the duplicate if it is present.
This is (probably) a regression in xkbcomp or xserver compared to the
versions used in Mac OS X. Since getting a patch for any of these two is
hopeless from my experience, I did not try to investigate further.
I am not sure why, but if I also add a `PC_SUPER_LEVEL2` type, the
duplicate of `FOUR_LEVEL_KEYPAD` doesn't show up. Hopefully the test

The current calculation is in short:
entry ? (entry->mask & ~entry->preserve) : 0
This changes it be
type->mask & ~(entry ? entry->preserve : 0)
This is what Xlib does. While less intuitive, it is actually more
correct, if you follow this deduction:
- The key group's type->mask defines which modifiers the key even cares
about. The others are completely irrelevant (and in fact they are
masked out from all sided in the level calculation). Example: NumLock
for an alphabetic key.
- The type->mask, the mods which are not masked out, are *all* relevant
(and in fact in the level calculation they must match *exactly* to the
state). These mods affect which level is chosen for the key, whether
they are active or not.
- Because the type->mask mods are all relevant, they must be considered
as consumed by the calculation *even if they are not active*.
Therefore we use type->mask instead of entry->mask.
The second change is what happens when no entry is found: return 0 or
just take preserve to be 0? Let's consider an example, the basic type
type "ALPHABETIC" {
modifiers = Shift+Lock;
map[Shift] = Level2;
map[Lock] = Level2;
level_name[Level1] = "Base";
level_name[Level2] = "Caps";
};
Suppose Shift+Lock is active - it doesn't match any entry, thus it gets
to level 0. The first interpretation would take them both to be
unconsumed, the second (new one) would take them both to be consumed.
This seems much better: Caps is active, and Shift disables it, they both
do something.
This change also fixes a pretty lousy bug (since 0.3.2), where Shift
appears to apparently *not* disable Caps. What actually happens is that
Caps is not consumed (see above) but active, thus the implicit
capitalization in get_one_sym() kicks in and capitalizes it anyway.

These functions generally have the same effect as
xkb_state_key_get_syms() + xkb_keysym_to_utf{8,32}().
So why add them?
- They provide a slightly nicer interface, especially if the string is
the only interest.
- It makes the handling of multiple-keysyms-to-utf8 transparent. For the
designated use-case of multiple-keysyms (unicode combining
characters), this is a must. We also validate the UTF-8, which the
user might not otherwise do.
- We will need to apply some transformation on the resulting string
which depend on the xkb_state. This is not possible with the
xkb_keysym_* functions.

1000 is a bit too low for statistical significance on this 6 years old
CPU. Since the benchmark is run manually this shouldn't be a problem.

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.

Kind of odd, but get_one_sym() will be getting a different behavior.
Real life users *should* pick one or the other.

This is too strict, and causes symbols/cz to fail parsing. Instead, just
emit a warning (not shown by default):

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

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).

PATH_MAX is optional in POSIX, so avoid its unconditional usage
allocating and freeing buffers as needed.
To avoid too many malloc/free in the for loop in FindFileInXkbPath,
a buffer is grown according to the size needed at each iteration.
Needed for some tests. The tests need some adjustment, mostly because of
the resolution of xkeyboard-config bug
https://bugs.freedesktop.org/show_bug.cgi?id=50935
Also add the 'ch' symbols file for future tests.

This ensures the names are escaped before having any interaction with
the user.
This was caught by noticing dump(compile(dump())) != dump. Since that's
a nice test we add it to stringcomp.

Add three new pieces of API:
- xkb_keymap_min_keycode does what it says on the tin
- xkb_keymap_max_keycode likewise
- xkb_keymap_key_for_each calls the provided function once for every
valid key in the keymap

If the keycode range is smaller than 8 → 255, artifically widen it when
dumping the keymap as not to displease X.

The current API doesn't allow the caller to create keymaps from mmap()'ed
files. The problem is, xkb_keymap_new_from_string() requires a terminating
0 byte. However, there is no way to guarantee that when using mmap() so a
user currently has to copy the whole file just to get the terminating zero
byte (assuming they cannot use xkb_keymap_new_from_file()).
This adds a new entry xkb_keymap_new_from_buffer() which takes a memory
location and the buffer size in bytes.
Internally, we depend on yy_scan_{string,byte}() helpers. According to
flex documentation these already copy the input string because they are
wrappers around yy_scan_buffer().
yy_scan_buffer() on the other hand has some insane requirements. The
buffer must be writeable and the last two bytes must be ASCII-NUL. But the
buffer may contain other 0 bytes just fine.
Because we don't want these constraints in our public API,
xkb_keymap_new_from_buffer() needs to create a copy of the input memory.
But it then calls yy_scan_buffer() directly. Hence, we have the same
number of buffer-copies as with *_from_string() but without the
terminating 0 requirement.
The explicit yy_scan_buffer() call is preferred over yy_scan_byte() so the
buffer-copy operation is not hidden somewhere in flex.
Maybe some day we no longer depend on flex and can have a zero-copy API. A
user could mmap() a file and it would get parsed right from this buffer.
But until then, we shouldn't expose this limitation in the API but instead
provide an API that some day can work with zero-copy.
