Pierre Le Marre 1c1542d64f Tools: Add bash completions for xkbcli
- 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?

Pierre Le Marre 0d4541151f Keysyms: Fix failing tests
- 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.

Pierre Le Marre 0038c86607 Prevent overflow of octal escape sequences
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.

- Add corresponding test.
- Introduce the new message: XKB_WARNING_INVALID_ESCAPE_SEQUENCE.

Ran Benita a17701327e Compose: add iterator API
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.

Pierre Le Marre c0065c95a4 Messages: merge macros with and without message code
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`.

Keysyms: improve generator (#364)
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`.

Pierre Le Marre eafd3aceca Add a new warning for numeric keysyms
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.

Pierre Le Marre 417d0747b6 Add xkb-check-messages tool

Pierre Le Marre 399aa888e0 Use warning code in xkeyboard-config test 2023-09-19 08:49:52 +02:00
Pierre Le Marre ef81d04eef Structured log messages with a message registry
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.

Pierre Le Marre 44029221e8 Interactive tools: Escape control character for Unicode output
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.

Pierre Le Marre 266427723a Test: Catch SIGUSR1 from Xvfb for X11 tests
Based on the work done by Peter Hutterer. Original commit message:

If SIGUSR1 is set to SIG_IGN, X servers (all of them, including Xvfb)
will send that signal to the parent process when they're ready to accept
connections. We can use that instead of a hardcoded sleep which brings
the wait down to ~37ms on my box.

Pierre Le Marre 26b1a07659 Test: Use a xvfb wrapper for x11 test
The x11 test is currently silently skipped in CI, because it requires a
running X server.

Create a xvfb wrapper to run the test. We do not use `xvfb-run`, because
it is a shell script and it causes valgrind to detect unrelated memory
issues in the shell (dash, bash).

Improve wrapper using a special ELF section

TODO: The wrapper is intended to be used with the x11comp test as well.

compose: drop the 65535 node limit (#343)
In commit 1638409b22, the number of
compose nodes was limited to 65535 to enable "future optimizations",
which apparently means slightly reduced memory usage due to fitting in
a uint16_t. At this time, it was mentioned that the author was not
aware of "any compose files which come close".

However, I'm one of the users that actually do require a larger number
of nodes for their compose file. Thus, use a uint32_t again and raise
the limit significantly.

Add support for stable doc URLs (#342)
Doc URLs may change with time because they depend on Doxygen machinery.
This is unfortunate because it is good practice to keep valid URLs
(see: https://www.w3.org/Provider/Style/URI.html).

I could not find a built-in solution in Doxygen, so the solution proposed
here is to maintain a registry of all URLs and manage legacy URLs as
redirections to their canonical page.

This commit adds a registry of URLs that has three functions:
- Check no previous URL is now invalid.
- Add aliases for moved pages.
- Generate redirection pages for aliases. The redirection works with
  a simple <meta http-equiv="refresh"> HTML tag. See:
  https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta#http-equiv

This commit also initialize the URLs registry with current pages and some
redirections needed after recent documentation refactoring.

Finally, the CI is updated to catch any change that invalidate previous
URLs.
