This is a CLI keyboard layout switcher for Gnome 3 and 4x. It is not based on the X interface but rather implements direct D-Bus messaging with the Gnome Shell.
You can directly install this program by:
In Arch Linux, this program can be got from AUR.
paru -S g3kb-switchIn Fedora.
sudo dnf install g3kb-switchIn Nix / NixOS, official repository have included it.
nix-env -iA nixos.g3kb-switchYou can just run this program without installing it to your OS by
nix run 'github#lyokha/g3kb-switch' -- --helpBuild requires glib-2.0, so you need to install the corresponding development package.
In Ubuntu.
sudo apt-get install libglib2.0-devIn Fedora / RHEL / CentOS.
sudo dnf install glib2-develIn Gentoo.
sudo emerge -av dev-libs/glibCommands may differ in other Linux distributions.
Build and install the switcher.
cmake -Bbuild
cmake --build build
sudo cmake --install buildIn Gnome 41 and newer, the switcher will only work with G3kbSwitch Gnome Shell extension, because method org.gnome.Shell.Eval which was used in the original implementation of the switcher is now disabled for security reasons. Note that in Gnome 41 through 44 the extension differs from that which is required in Gnome 45, see build instructions for older Gnome versions in the next section.
You can use unsafe-mode-menu to toggle unsafe mode.
After installing the extension, restart Gnome Shell for changes to take effect.
It is wise to make sure that the extension is enabled and works correctly. To enable the extension, use program gnome-extensions-app or command-line program gnome-extensions.

(true, '')Older versions of Gnome Shell require a different implementation of the extension. In this case, the cmake configuration step requires one extra option.
Build and install the switcher.
cmake -Bbuild -DG3KBSWITCH_WITH_LEGACY_GNOME_SHELL_EXTENSION=ON
cmake --build build
sudo cmake --install buildEven older versions of Gnome Shell expose method org.gnome.Shell.Eval which means that the switcher can be built to work with this method rather than using the extension. In this case, the cmake configuration step requires one extra option.
Build and install the switcher.
cmake -Bbuild -DG3KBSWITCH_WITH_GNOME_SHELL_EXTENSION=OFF
cmake --build build
sudo cmake --install buildAfter cmake --build build, run:
cd build

let g:XkbSwitchEnabled = 1
let g:XkbSwitchLib = '/usr/local/lib64/libg3kbswitch.so'Variable g:XkbSwitchLib must contain the actual path to the installed library. The path can be found with pkg-config.
$ pkg-config g3kb-switch --variable libpath
/usr/local/lib64/libg3kbswitch.soNotice that setting this variable is optional because vim-xkbswitch tries its best to autodetect the path.
See details about configuration rules for vim-xkbswitch here.
