Add excerpt of `util-mem.h` from libei defining the macro `steal`, in
order to improve memory management and the code semantics.
See: 38132d6fc5/src/util-mem.h (L92)
Previously the attribute “popularity” was completely ignored. It also
did not respect the modified DTD, because its default value depends if
we are currently parsing an “extras” rules file.
Fixed:
- Always parse the popularity attribute.
- Change the DTD to reflect that the default value is implied.
Current options to set the locale are convoluted:
- An explicit locale *must* be given, while a sane default would be
to use the user environment.
- Then there are two options that were useful while testing locale
handling: read environment variables or use `setlocale`. But the
program has already called:
```
setlocale(LC_ALL, "");
```
so it turns out the two options lead to the same results.
Remove options `--locale-from-env` and `--locale-from-setlocale`
and make the locale default to the user environment.
- Add check for recursive includes of keymap components. It relies on
limiting the include depth. The threshold is currently to 15, which
seems reasonable with plenty of margin for keymaps in the wild.
- Add corresponding new log message `recursive-include`.
- Add tests for recursive includes.
The string `buf` was not freed after each call to `asprintf_safe`.
Avoid allocating and introduce the new message: `XKB_ERROR_INSUFFICIENT_BUFFER_SIZE`.
When there is no error the types are “stolen” and copied to the keymap.
But when there is an error, `MergeIncludedKeyTypes` just return without
“stealing” nor freeing the types.
Fixed by explicitly freeing the key types.
Fixed another leak in `HandleKeyTypeDef` that may occur if there is an
error in parsing a type definition.
GCC 14 introduces a new -Walloc-size included in -Wextra which gives:
```
src/state.c:589:9: warning: allocation of insufficient size ‘1’ for type ‘struct xkb_state’ with size ‘128’ [-Walloc-size]
```
The calloc prototype is:
```
void *calloc(size_t nmemb, size_t size);
```
So, just swap the number of members and size arguments to match the prototype, as
we're initialising 1 struct of size `sizeof(struct xkb_state)`. GCC then sees we're not
doing anything wrong.

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.
- Add bash completion script. It parses the commands help messages to
provide the completions, thus any new subcommand or option will be
supported, as long as it has its entry in the help messages. This
should result in low maintenancei effort.
- Add installation entry in Meson. The path can be configured using
the following options:
- `enable-bash-completion` to enable the installation;
- `bash-completion-path` to control the installation path. It will
default to: `share/bash-completion/completions`.
TODO: completion for other shells, such as zsh?
See https://pre-commit.com for further info. Current checks:
- Whitespaces
- Yaml
- Large files
- Python linting/formatting
TODO: investigate options for C linter and formatter
- Update keymap to use reference keysym names.
- Fix x11comp test by handling old x11proto.
We need xkbcomp to be compiled with at least x11proto-dev 2023.2.
So we replace the unsupported keysyms with supported ones not
already in the keymap. This is kind of ugly, but it works. If we
ever want to restore the original keysyms with their supported names,
the substitute keysyms will be easy to spot.
The octal parser accepts the range `\1..\777`. The result is cast to
`char` which will silently overflow.
This commit prevents overlow and will treat `\400..\777` as invalid
escape sequences.
NULL usually terminates the strings; allowing to produce it via escape
sequences may lead to undefined behaviour.
- Make NULL escape sequences (e.g. `\0` and `\x0`) invalid.
- Add corresponding test.
- Introduce the new message: XKB_WARNING_INVALID_ESCAPE_SEQUENCE.
Allow users to iterate the entries in a compose table. This is useful
for other projects which want programmable access to the sequences,
without having to write their own parser.
- New API:
- `xkb_compose_table_entry_sequence`;
- `xkb_compose_table_entry_keysym`;
- `xkb_compose_table_entry_utf8`;
- `xkb_compose_table_iterator_new`;
- `xkb_compose_table_iterator_free`;
- `xkb_compose_table_iterator_next`.
- Add tests in `test/compose.c`.
- Add benchmark for compose traversal.
- `tools/compose.c`:
- Print entries instead of just validating them.
- Add `--file` option.
- TODO: make this tool part of the xkbcli commands.

Previously we had two types of macros for logging: with and without
message code. They were intended to be merged afterwards.
The idea is to use a special code – `XKB_LOG_MESSAGE_NO_ID = 0` – that
should *not* be displayed. But we would like to avoid checking this
special code at run time. This is achieved using macro tricks; they
are detailed in the code (see: `PREPEND_MESSAGE_ID`).
Now it is also easier to spot the remaining undocumented log entries:
just search `XKB_LOG_MESSAGE_NO_ID`.
Motivation: normalization of keysyms header files in `xorgproto`. See:
https://gitlab.freedesktop.org/xorg/proto/xorgproto/-/merge_requests/80
Improve `scripts/makeheader`:
- Simplify `evdev` and `XK_` substitution and improve alignment. Also, perform
some additional `XK_` substitutions in comments.
- Format with `black`.
Usually it is better to use the corresponding human-friendly keysym
names. If there is none, then the keysym is most probably not
supported in the ecosystem. The only use case I see is similar to the
PUA in Unicode (see: https://en.wikipedia.org/wiki/Private_Use_Areas).
I am not aware of examples of this kind of use.
This tool checks whether messages codes are supported.
This is useful e.g. for CI, where one may want to grep for some XKB
error codes and ensure that these are still supported.
Currently there is little structure in the log messages, making
difficult to use them for the following use cases:
- A user looking for help about a log message: the user probably
uses a search engine, thus the results will depend on the proper
indexing of our documentation and the various forums. It relies
only on the wording of the message, which may change with time.
- A user wants to filter the logs resulting of the use of one of the
components of xkbcommon. A typical example would be testing
xkeyboard-config against libxkbcommon. It requires the use of a
pattern (simple words detection or regex). The issue is that the
pattern may become silently out-of-sync with xkbcommon.
A common practice (e.g. in compilers) is to assign unique error codes
to reference theses messages, along with an error index for
documentation.
Thus this commit implements the following features:
- Create a message registry (message-registry.yaml) that defines the
log messages produced by xkbcommon. This is a simple YAML file that
provides, for each message:
- A unique numeric code as a short identifier. It is used in the
output message and thus can be easily be filtered to spot errors
or searched in the internet. It must not change: if the
semantics of message changes, it is better to introduce a new
message for clarity.
- A unique text identifier, meant for two uses:
1. Generate constants dealing with log information in our code
base.
2. Generate human-friendly names for the documentation.
- A type: currently warning or error. Used to prefix the constants
(see hereinabove) and for basic classification in documentation.
- A short description, used as concise and mandatory documentation.
- An optionnal detailed description.
- Optional examples, intended to help the user to fix issues
themself.
- Version of xkbcommon it was added. For old entries this often
unknown, so they will default to 1.0.0.
- Version of xkbcommon it was removed (optional)
No entry should ever be deleted from this index, even if the message
is not used anymore: it ensures we have unique identifiers along the
history of xkbcommon, and that users can refer to the documentation
even for older versions.
- Add the script update-message-registry.py to generate the following
files:
- messages.h: message code enumeration for the messages currently
used in the code base. Currently a private API.
- message.registry.md: the error index documentation page.
- Modify the logging functions to use structured messages. This is a
work in progress.
Add an option to print modmap and vmodmap of relevant keys, as well as
virtual modifiers mapping to real modifier. This is useful for debugging.
It uses private API, so we compile it separately in the fashion of
`xkbcli-compile-keymap/compile-keymap`.
Currently the interactive tools print the string result of key strokes
as it is, without any escape. This is especially annoying for trivial
keysyms such as: Return, BackSpace and Escape.
Fix this by displaying the Unicode code point notation (e.g U+000D for
Return) for single control characters from the C0 set and DEL.
This is a hack: ideally we would like to escape any non-printable
character in the utf-8 string.
