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.

Building

libxkbcommon is built the typical autoconf way:

./autogen.sh
make

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

./autogen.sh --disable-x11 \
    --with-xkb-config-root=/usr/share/X11/xkb \
    --with-x-locale-root=/usr/share/X11/locale
make

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:

http://www.freedesktop.org/wiki/Software/XKeyboardConfig

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

Relation to X11
