9e93e5e5 | 2025-04-13 10:25:02 | symbols: Restrict the number of actions and keysyms per level In preparation to support capitalization in `xkb_state_key_get_syms()`, this commit reduces the number of supported actions and keysyms per level, going from UINT_MAX to UINT16_MAX. This is most likely still more than enough and could be even reduced further, but deemed unnecessary at the moment: alignment of `struct xkb_level` is driven by the fields `a` and `s`. - Switched the item count type from `unsigned int` to `uint16_t`. - Introduced `xkb_{action,keysym}_count_t` type for the respective item count for exact typing. - Added relevant bounds checks. | |

cb3565b1 | 2025-03-07 17:59:33 | keymap: Fix segfault due to invalid group wrapping The modular arithmetic is incorrect for negative values, e.g. for num_groups = 1. It triggers a segfault for the following settings: - layouts count (per key or total) N: `N > 0`, and - layout index n: `n = - k * N` (`k > 0`) % returns the *remainder* of the division, not the modulus (see C11 standard 6.5.5 “Multiplicative operators”: a % b = a - (a/b)*b. While both operators return the same result for positive operands, they do not for e.g. a negative dividend: remainder may be negative (in the open interval ]-num_groups, num_groups[) while the modulus is always positive. So if the remainder is negative, we must add `num_groups` to get the modulus.

5ef19bcf | 2025-02-13 17:58:21 | xkbcomp: Fix incorrect memory comparison Spotted by clang-tidy: ``` ../src/keymap-priv.c:146:16: warning: comparing object representation of type 'union xkb_action' which does not have a unique object representation; consider comparing the members of the object manually [bugprone-suspicious-memory-comparison] ```` Indeed, from “EXP42-C. Do not compare padding data”[^1]: > unnamed members of objects of structure and union type do not participate > in initialization. Unnamed members of structure objects have indeterminate > representation even after initialization. Fixed by using a dedicated comparison function for `union xkb_action`.

fdf2c525 | 2024-10-08 19:43:30 | actions: Add support for multiple actions per level This makes 1 keysym == 1 action holds also for multiple keysyms per level. The motivation of this new feature are: - Make multiple keysyms per level more intuitive. - Explore how to fix the issue with shortcuts in multi-layout settings (see the xkeyboard-config issue[^1]). The idea is to use e.g.: ```c key <LCTL> { symbols[1] = [ {Control_L, ISO_First_Group } ], actions[1] = [ {SetMods(modifiers=Control), SetGroup(group=-4) } ] }; ``` in order to switch temporarily to a reference layout in order to get the same shortcuts on every layout. When no action is specified, `interpret` statements are used to find an action corresponding for *each* keysym, as expected. For an interpretation matching Any keysym, we may get the same interpretation for multiple keysyms. This may result in unwanted duplicate actions. So set this interpretation only if no previous keysym was matched with this interpret at this level, else set the default interpretation. For now, at most one action of each following categories is allowed per level: - modifier actions: `SetMods`, `LatchMods`, `LockMods`; - group actions: `SetGroup`, `LatchGroup`, `LockGroup`. Some examples: - `SetMods` + `SetGroup`: ok - `SetMods` + `SetMods`: error - `SetMods` + `LockMods`: error - `SetMods` + `LockGroup`: ok [^1]: https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/issues/416 | |

40aab05e | 2019-12-27 13:03:20 | build: include config.h manually Previously we included it with an `-include` compiler directive. But that's not portable. And it's better to be explicit anyway.

787faf36 | 2014-04-22 12:23:36 | keymap: don't use darray in xkb_mod_set Instead just statically allocate the mods array (of size MAX_MOD_SIZE = 32). The limit is not going anywhere, and static allocations are nicer (nicer code, no OOM, etc.). It's also small and dense enough. Signed-off-by: Ran Benita <ran234@gmail.com> | |

ca3170ad | 2013-02-08 13:09:33 | Add struct xkb_mod_set The only thing that the compilation phase needs the keymap for currently is for access to the modifier information (it also modifies it in place!). We want to only pass along the neccessary information, to make it more tractable and testable, so instead of passing the entire keymap we add a new 'mod_set' object and pass a (const) reference to that. The new object is just the old array of 'struct xkb_mod'. Signed-off-by: Ran Benita <ran234@gmail.com> | |
