doc: Fix link to modules It’s a breaking change of Doxygen. Now it’s called “topics”.
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.
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
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 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.
See Compatibility notes.

Patches are always welcome, and may be sent to either xorg-devel@lists.x.org or wayland-devel@lists.freedesktop.org or in a GitHub pull request.
Bug reports (and usage questions) are also welcome, and may be filed at GitHub.

# 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 *registry* library for listing available keyboard
layouts.

a *custom layout* or option.

## Building
libxkbcommon is built with [Meson](http://mesonbuild.com/):
```bash
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:
```bash
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.

## 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][xkeyboard-config-home] and at
its [repository][xkeyboard-config-repo].
The dataset for *Compose* is distributed in [libX11], as part of the X locale
data.
