    Add fuzzing infrastructure Though text formats aren't exactly fuzzer's strong suit, fuzzers can catch many surface-level bugs. The fuzz/ directory contains target programs, testcases and dictionaries to drive the afl fuzzer. This commit adds a fuzzer for the XKB keymap text format and the Compose text format. On my slow machine, using a single core, a full cycle of the XKB fuzzer takes 5 hours. For Compose, it takes a few minutes. Fuzzing for the other file formats (rules files mostly) will be added later. To do some fuzzing, run `./fuzz/fuzz.sh`. Signed-off-by: Ran Benita <ran234@gmail.com>

    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.

    Quick Guide

    See Quick Guide.

    Building

    libxkbcommon is built with Meson:

    meson setup build
ninja -C build

    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
ninja -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
