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.
See Quick Guide.
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
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.
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.
