    tools: change xkbcli list to output YAML

We have a lot of keyboard layouts and the current output format is virtually
useless at searching for a specific one to debug any issues with either the
layout list or the output from libxkbregistry.

Let's use YAML instead because that can easily be post-processed to extract the
specific layouts wanted, e.g. to get the list of all layouts:
  xkbcli-list | yq -r ".layouts[].layout"
to get the list of all variants of the "us" layout:
  xkbcli-list | yq -r '.layouts[] | select(.layout == "us") | .variant
and the number of option groups:
  xkbcli-list | yq -r '.option_groups[] | length'

Note that the top-level nodes have been de-capitalized, so where it was "Models"
before it is now "models" and the "Options" node is now "option_groups".

  • 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

    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
