Pierre Le Marre e1892266 2025-02-13T16:57:46 clang-tidy: Miscellaneous fixes
Pierre Le Marre ce9bcbe0 2025-02-07T16:31:37 scripts: Rename keysyms-related files Previous names were too generic. Fixed by using explicit names and add the `.py` file extension.
Ran Benita df2322d7 2025-02-05T14:41:21 Replace include guards by `#pragma once` We currently have a mix of include headers, pragma once and some missing. pragma once is not standard but is widely supported, and we already use it with no issues, so I'd say it's not a problem. Let's convert all headers to pragma once to avoid the annoying include guards. The public headers are *not* converted. Signed-off-by: Ran Benita <ran@unusedvar.com>
Pierre Le Marre 1d897502 2024-10-04T08:09:28 keysyms: Update using latest xorgproto xorgproto commit: d7ea44d5f04cc476dee83ef439a847172f7a6bd1 Relevant MR: https://gitlab.freedesktop.org/xorg/proto/xorgproto/-/merge_requests/91
Pierre Le Marre 378badab 2024-09-19T17:30:55 Add function xkb_keysym_is_deprecated This function allow to check whether a keysym is deprecated, based on the keysym and optionally its name. The generation of the table of deprecated keysyms relies on the rules described in `xkbcommon-keysyms.h`. The `ks_table.h` is now generated deterministically by setting explicitly the random seed to a constant. This will avoid noisy diffs in the future.
Pierre Le Marre 53d9881e 2024-03-05T10:28:11 keysyms: Fix inconsistent case-insensitive name lookup `xkb_keysym_from_name` has inconsistent behavior when used with the flag `XKB_KEYSYM_CASE_INSENSITIVE`: ```c xkb_keysym_from_name("a", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_a; xkb_keysym_from_name("A", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_a; xkb_keysym_from_name("dead_a", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_dead_A; xkb_keysym_from_name("dead_A", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_dead_A; xkb_keysym_from_name("dead_o", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_dead_o; xkb_keysym_from_name("dead_O", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_dead_o; xkb_keysym_from_name("KANA_tsu", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_kana_tsu; xkb_keysym_from_name("KANA_TSU", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_kana_tsu; xkb_keysym_from_name("KANA_ya", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_kana_YA; xkb_keysym_from_name("KANA_YA", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_kana_YA; xkb_keysym_from_name("XF86Screensaver", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_XF86ScreenSaver; xkb_keysym_from_name("XF86ScreenSaver", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_XF86ScreenSaver; ``` So currently, if two keysym names differ only by case, then the lower-case *keysym* is returned, not the keysym corresponding to the lower-case keysym *name*. Indeed, `xkb_keysym_from_name` uses `xkb_keysym_is_lower` to test if a keysym is a lower-case keysym. Let’s look at the example for keysyms `a` and `A`: we get the keysym `a` not because its name is lower case, but because `xkb_keysym_is_lower(XKB_KEY_a)` returns true and `xkb_keysym_is_lower(XKB_KEY_A)` returns false. So the results are correct according to the doc: - Katakana is not a bicameral script, so e.g. `kana_ya` is *not* the lower case of `kana_YA`. - As for the `dead_*` keysyms, they are not cased either because they do not correspond to characters. - `XF86ScreenSaver` and `XF86Screensaver` are two different keysyms. But this is also very counter-intuitive: `xkb_keysym_is_lower` is not the right function to use in this case, because one would expect to check only the name, not the corresponding character case: ```c xkb_keysym_from_name("KANA_YA", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_kana_ya; xkb_keysym_from_name("XF86ScreenSaver", XKB_KEYSYM_CASE_INSENSITIVE) == XKB_KEY_XF86Screensaver; ``` Fixed by making the order of the keysyms names consistent in `src/ks_tables.h`: 1. Sort by the casefolded name: e.g. `kana_ya` < `kana_YO`. 2. If same casefolded name, then sort by cased name, i.e for ASCII: upper before lower: e.g `kana_YA` < `kana_ya`. Thus we now have e.g. `kana_YA` < `kana_ya` < `kana_YO` < `kana_yo`. The lookup logic has also been simplified. Added exhaustive test for ambiguous case-insensitive names.

Pierre Le Marre 382f6d2d 2024-02-05T08:57:35 Keysyms: Update using latest xorgproto For the sake of compatibility, this reintroduce some deleted keysyms and postpone the effective deprecation of others. xorgproto commit: fe12c5102762afcbf852e50dcbbdea2ef625570c Also added tests for some canonical names.
Pierre Le Marre 238d1324 2023-09-29T11:33:28 Keysyms: Fix missing hpYdiaeresis The handling of keysym name guards (e.g. `#ifndef XK_Ydiaeresis`) was incomplete and led to a missing keysym. Make `sripts/makeheader` more robust to C macros handling.

Ran Benita 68e69b7d 2021-03-28T20:22:54 keysym: use a perfect hash function for case sensitive xkb_keysym_from_name In 7d84809fdccbb5898d0838849ec7c321410182d5 I added a fast path for the case-sensitive case, but it is still slowing down Compose parsing. Instead of the binary search, use a perfect hash function, computed with a simple python module I found (vendored).

Ran Benita 7d84809f 2021-03-28T15:51:01 keysym: fast path for case sensitive xkb_keysym_from_name xkb_keysym_from_name() is called a lot in Compose file parsing. The lower case handling slows things down a lot (particularly given we can't use the optimized strcasecmp() due to locale issues). So add separate handling for the non-case-sensitive case which is used by Compose. To do this we need to add another version of the ks_tables table. This adds ~20kb to the shared library binary. We can probably do something better here but I think it's fine. Signed-off-by: Ran Benita <ran@unusedvar.com>

Ran Benita 5d9a5cb0 2012-10-17T19:52:47 Commit and distribute ks_tables.h The ks_tables.h file is generated by makekeys.py from xkbcommon-keysyms.h, which in turn is generated initially by 'make update-keysyms'. The xkbcommon-keysyms.h file is commited to git and distributed in the tarball. Since ks_tables.h should only ever change when xkbcommon-keysyms.h changes, it is more sensible to update them together and treat them the same, instead of generating ks_tables.h every time for every builder with 'make', as we do now. This means we don't need python as a build dependency (only the one running update-keysyms, i.e. no one, needs this), and we can be sure exactly the same file is used by everyone. We also don't need to run makekeys.py on every build. Signed-off-by: Ran Benita <ran234@gmail.com>
