Currently xkb_keymap_num_leds() returns a count of valid (settable)
leds. Because the indexes might be non-consecutive, and some leds
might not be settable, it is incorrect to use this function for
iterating over the leds in the keymap. But this is the main use case of
this function, so instead of the current behavior we adapt the function
to the use case by making it return the needed range of iteration.
The caller needs to handle invalid intermittent indexes, though.

Using NOCONFIGURE=1 ./autogen.sh can prevent it from running ./configure

Use a darray instead of a static array of size 32.
We still enforce XKB_MAX_LEDS because of the size of xkb_led_mask_t.

xkb_keymap_num_leds() returns the number of leds that have any
possibility of being set. Even if a led is defined but can not be set in
any way, it is not counted.
In a few places currently we assume that led indexes are smaller than
this number, which is wrong both for the above reason and for the fact
that the xkb format actually allows explicitly setting the indicator
index, which means that the indexes might be non-consecutive.
We don't really have good API to iterate on leds, now, because
xkb_keymap_num_leds is pretty useless. To work around that we use
sizeof(xkb_led_mask_t) * 8.
This makes the "Group 2" led work (try switching to a layout other than
the first in test/interactive).

Our current code (taken from the xserver) doesn't handle unicode keysyms
at all, and there seem to be some other changes compared to libX11,
which is what xkbcomp uses. So we just copy the code that does that from
libX11.
It would be much better to not have to hardcode unicode tables like
that, but it's probably better than dealing with glibc locale stuff for
now. It also doesn't affect our binary size much.

Commit 9984d1d03c changed the type of
interpret->mods to xkb_mod_mask_t, but this bit of code assumes that the
type is uint8_t.
This code is not usually run (for example by our tests), but when it
does keymap-dump would print out all of the modifiers (including the
virtual ones) which causes recompilation of the output to fail
miserably.

These are both real modifier masks, but we keep this information only in
the program logic now so when we change it we don't have to worry about
the type.

This again pushes the mod type annotation to the original call site, to
make it easier to grep to see where the real/virtual distinction
matters.
Signed-off-by: Ran Benita <ran234@gmail.com>
Most of the mod type annotations can now be changed to MOD_BOTH, because
if you pass a mask which can only contain real mods in the first place to
e.g. ModMaskText, then MOD_REAL and MOD_BOTH will give the same result.
In the cases where MOD_BOTH is only ever the argument, we just remove
it. What's left is where it really "matters".

This essentially "tags" each invocation of the functions with the
modifier type of the argument, which allows for easy grepping for them
(with the aim being, to remove anything but MOD_BOTH).

We change the keymap->vmods array into keymap->mods, and change it's
member type from struct xkb_vmod to struct xkb_mod. This table now
includes the real modifiers in the first 8 places. To distinguish
between them, we add an enum mod_type to struct xkb_mod.
Besides being a more reasonable approach, this enables us to share
some code later, remove XKB_NUM_CORE_MODS (though the 0xff mask still
appears in a few places), and prepares us to flat out remove the
distinction in the future. This commit just does the conversion.

Modifier masks can be confusing in some places. For example,
key->vmodmap only contains virtual modifiers, where the first is in
position 0, the second in 1 etc., while normally in a xkb_mod_mask_t the
virtual modifiers start from the 8th (XKB_NUM_CORE_MODS) position. This
happens in some other places as well.
Change all of the masks to be in the usual real+virtual format, and when
we need to access e.g. keymap->vmods we just adjust by
XKB_NUM_CORE_MODS. (This also goes for indexes, e.g.
interpret->virtual_modifier).
This makes this stuff easier to reason about.

VModInfo currently is only used to track which virtual modifiers were
declared in the file which owns the VModInfo. This, in turn, is only
used in ResolveVirtualModifier, which in turn is only used to resolve
the virtualModifier field in an interpret statement (compat.c). In other
words, it is used to ensure that interprets can only use a vmod which
was declared in the same map.
We remove this now, because it doesn't do much and distracts from other
changes; we will later re-add it properly. Specificly, we will make it
so that virtual modifiers are not the exception in that they modify the
keymap directly, instead of keeping the changes in some *Info struct and
commiting them to the keymap at the end of the compilation. (This is bad
because if a vmod is added to the keymap, and then the compilation of
this specific file fails, the change sticks around nonetheless).

LookupModMask handles this before calling LookupModIndex, and the only
other user in symbols.c doesn't handle this return value at all.

Turn the virtual modifiers arrays in the keymap to a single darray,
which doesn't use this limit. The number of virtual modifiers is still
limited by the size of xkb_mod_mask_t, so we make sure not to go over
that.

This is a regression introduced in ed78fbcb30.
XKB_STATE_EFFECTIVE is just a OR of the other states, so using & here is
completely wrong. So test/state shows for example:
dumping state for LCtrl down:
group English (US) (0): effective depressed latched locked
mod Control (2): depressed latched locked
dumping state for LCtrl + RAlt down:
group English (US) (0): effective depressed latched locked
mod Control (2): depressed latched locked
mod Mod1 (3): depressed latched locked
dumping state for RAlt down:
group English (US) (0): effective depressed latched locked
mod Mod1 (3): depressed latched locked
dumping state for Caps Lock:
group English (US) (0): effective depressed latched locked
mod Lock (1): depressed latched locked
led Caps Lock (0): active
dumping state for Alt-Shift-+
group English (US) (0): effective depressed latched locked
mod Shift (0): depressed latched locked
mod Mod1 (3): depressed latched locked
which is bogus.

One physical xkb file may (and usually does) contain multiple maps. For
example, the us symbols file contains a map for every variant.
Currently, when we need a map from a file (specific or default), we
parse the entire file into a list of XkbFile's, find the map we want and
discard the others. This happens for every include statement. This is a lot
of unnecessary work; this commit is a first step at making it better.
What we do now is make yyparse return one map at a time; if we find what
we want, we can stop looking and avoid processing the rest of the file.
This moves some logic from include.c to parser.y (i.e. finding the
correct map, named or default). It also necessarily removes the
CheckDefaultMap check, which warned about a file which contains multiple
default maps. We can live without it.
Some stats with test/rulecomp (under valgrind and the benchmark):
Before:
==2280== total heap usage: 288,665 allocs, 288,665 frees, 13,121,349 bytes allocated
compiled 1000 keymaps in 10.849487353s
After:
==1070== total heap usage: 100,197 allocs, 100,197 frees, 9,329,900 bytes allocated
compiled 1000 keymaps in 5.258960549s
Pretty good.
Note: we still do some unnecessary work, by parsing and discarding the
maps before the one we want. However dealing with this is more
complicated (maybe using bison's push-parser and sniffing the token
stream). Probably not worth it.

This rule allows you to put several xkb_keymaps in one file.
This doesn't make any sense: only the default/first can ever be used,
yet the others are fully parsed as well.
Different keymaps should just be put in different files.

This rule allows you to write file maps as:
xkb_keycodes
<BLA> = 5;
[...]
instead of the usual format which is:
xkb_keycodes {
<BLA> = 5;
[...]
};
This is not documented, It is also not used in xkeyboard-config, and I
have never run into it otherwise. It also only allows one map per file.
It *might* be used in some obscure place, but probably nothing we should
care about; the simplified grammar is more useful for us now.

This is a proof-of-concept for the long key names. The keycodes in the
file evdev-xkbcommon are autogenerated from linux/input.h, and uses the
names given there; all of the previous names are aliased to the new
names, so they continue to work with the symbols files, etc.
You can try it with 'sudo ./test/interactive -r evdev-xkbcommon -n 0'
The -n 0 means that we don't offset the evdev scan codes - just feed
them directly. The -r evdev-xkbcommon just means to use a new rules file
which makes us use the new keycodes file. (The only problem I can see is
with the MENU and LSGT names which has some conflicts).
Maybe some day xkeyboard-config could ship something similar, so that
the 8 offset is unneeded.
