    Message : rules: Fix wild card handling The handling of wild card `*` is different in libxkbfile and X server: wild card matches empty strings for model and option but not for layout nor variant, while in libxkbcommon wild cards always match empty strings. See: - https://gitlab.freedesktop.org/xorg/lib/libxkbfile/-/blob/bf985c68acb1244f51ec91414532a2347fbc1c4c/src/maprules.c#L687 - https://gitlab.freedesktop.org/xorg/lib/libxkbfile/-/blob/bf985c68acb1244f51ec91414532a2347fbc1c4c/src/maprules.c#L712 The difference of handling between the components is unfortunately not documented, but we should follow the behavior of the original implementations for consistency. - Fixed by implementing the same behavior than libxkbfile. - Added tests and fixed failing tests. - Improve the documentation of rules to highlight the special behavior.

  • libxkbcommon

    libxkbcommon is a keyboard keymap compiler and support library which processes a reduced subset of keymaps as defined by the XKB (X Keyboard Extension) specification. It also contains a module for handling Compose and dead keys and a separate library for listing available keyboard layouts.

    Quick Guide

    Building

    libxkbcommon is built with Meson:

    meson setup build
meson compile -C build
meson test -C build # Run the tests.

    To build for use with Wayland, you can disable X11 support while still using the X11 keyboard configuration resource files thusly:

    meson setup build \
    -Denable-x11=false \
    -Dxkb-config-root=/usr/share/X11/xkb \
    -Dx-locale-root=/usr/share/X11/locale
meson compile -C build

    API

    While libxkbcommon's API is somewhat derived from the classic XKB API as found in X11/extensions/XKB.h and friends, it has been substantially reworked to expose fewer internal details to clients.

    See the API Documentation.

    Dataset

    libxkbcommon does not distribute a keymap dataset itself, other than for testing purposes. The most common dataset is xkeyboard-config, which is used by all current distributions for their X11 XKB data. More information on xkeyboard-config is available here: https://www.freedesktop.org/wiki/Software/XKeyboardConfig

    The dataset for Compose is distributed in libX11, as part of the X locale data.

    Relation to X11
