Complete list of user options 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 registry library for listing available keyboard layouts.

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 keyboard layout 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. Further information on xkeyboard-config is available at its homepage and at its repository.

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

Relation to X11

See Compatibility notes.
