kalamine 0.22

a cross-platform Keyboard Layout Maker

A text-based, cross-platform Keyboard Layout Maker.

Install

All you need is a Python environment:

python3 -m pip install kalamine

Developers can also install it from the current directory:

python3 -m pip install -e .

And to uninstall kalamine:

python3 -m pip uninstall kalamine

If your system requires a python virtual environment, check the XKalamine/pyenv section at the end of this document (you can skip the sudo su command to install as user).

If you get a UnicodeEncodeError on Windows, try specifying this environment variable before executing Kalamine:

$Env:PYTHONUTF8 = 1

Building Distributable Layouts

Draw your keyboard layout in one of the provided ASCII-art templates and include it in a TOML document:

name = "qwerty-ansi"
name8 = "q-ansi"
description = "QWERTY-US layout"
version = "1.0.0"
geometry = "ANSI"

base = '''

Build it:

kalamine layouts/ansi.toml

Get all distributable keyboard drivers:

dist/
 ├─ q-ansi.klc         # Windows
 ├─ q-ansi.keylayout   # macOS
 ├─ q-ansi.xkb         # Linux (user)
 ├─ q-ansi.xkb_custom  # Linux (root)
 └─ q-ansi.json        # web

You can also ask for a single target by specifying the file extension:

kalamine layouts/ansi.toml --out q-ansi.xkb_custom

Emulating Layouts

Your layout can be emulated in a browser — including dead keys and an AltGr layer, if any.

$ kalamine layouts/prog.toml --watch
Server started: http://localhost:8080

Open your browser, type in the input area, test your layout. Changes on your TOML file are not auto-detected yet, you’ll have to refresh the page manually.

Press Ctrl-C when you’re done, and kalamine will write all platform-specific files.

Installing Distributable Layouts

Windows

• get a keyboard layout installer: MSKLC (freeware) or KbdEdit (shareware);

• load the *.klc file with it;

• run this installer to generate a setup program;

• run the setup program;

• the keyboard layout appears in the language bar.

macOS

• copy your *.keylayout file into:

  • either ~/Library/Keyboard Layouts for the current user only,

  • or /Library/Keyboard Layouts for all users;

• restart your session;

• the keyboard layout appears in the “Language and Text” preferences, “Input Methods” tab.

Linux (root)

Recent versions of XKB allow one custom keyboard layout in root space:

sudo cp layout.xkb_custom ${XKB_CONFIG_ROOT:-/usr/share/X11/xkb}/symbols/custom

Your keyboard layout will be listed as “Custom” in the keyboard settings. This works on both Wayland and X.Org. Depending on your system, you might have to relog to your session or to reboot X completely.

On X.Org you can also select your keyboard layout from the command line:

setxkbmap custom  # select your keyboard layout
setxkbmap us      # get back to QWERTY

On Wayland, this depends on your compositor. For Sway, tweak your keyboard input section like this:

input type:keyboard {
    xkb_layout "custom"
}

Linux (user)

*.xkb keyboard descriptions can be applied in user-space. The main limitation is that the keyboard layout won’t show up in the keyboard settings.

On X.Org it is straight-forward with xkbcomp:

xkbcomp -w10 layout.xkb $DISPLAY

Again, setxkbmap can be used to get back to the standard us-qwerty layout on X.Org:

setxkbmap us

On Wayland, this depends on your compositor. For Sway, tweak your keyboard input section like this:

input type:keyboard {
    xkb_file /path/to/layout.xkb
}

XKalamine

xkalamine is a Linux-specific CLI tool for installing and managing keyboard layouts with XKB, so that they can be listed in the system’s keyboard preferences.

Wayland (user)

On Wayland, keyboard layouts can be installed in user-space:

# Install a YAML/TOML keyboard layout into ~/.config/xkb
xkalamine install layout.toml

# Uninstall Kalamine layouts from ~/.config/xkb
xkalamine remove us/prog     # remove the kalamine 'prog' layout
xkalamine remove fr          # remove all kalamine layouts for French
xkalamine remove "*"         # remove all kalamine layouts

# List available keyboard layouts
xkalamine list               # list all kalamine layouts
xkalamine list fr            # list all kalamine layouts for French
xkalamine list us --all      # list all layouts for US English
xkalamine list --all         # list all layouts, ordered by locale

Once installed, layouts are selectable in the desktop environment’s keyboard preferences. On Sway, you can also select a layout like this:

input type:keyboard {
    xkb_layout "us"
    xkb_variant "prog"
}

X.Org (root)

On X.Org, a layout can be applied on the fly in user-space:

# Equivalent to `xkbcomp -w10 layout.xkb $DISPLAY`
xkalamine apply layout.toml

However, installing a layout so it can be selected in the keyboard preferences requires sudo privileges:

# Install a YAML/TOML keyboard layout into /usr/share/X11/xkb
sudo xkalamine install layout.toml

# Uninstall Kalamine layouts from /usr/share/X11/xkb
sudo xkalamine remove us/prog
sudo xkalamine remove fr
sudo xkalamine remove "*"

Once installed, you can apply a keyboard layout like this:

setxkbmap us -variant prog

Note that updating XKB will delete all layouts installed using sudo xkalamine install.

Besides, using xkalamine with sudo supposes kalamine has been installed as root — hopefully in a pyenv:

python -m venv /path/to/pyenv      # create a pyenv (if you don’t already have one)
cd /path/to/pyenv/bin
sudo su                            # get root privileges
./python -m pip install kalamine   # install Kalamine in the pyenv (don't forget `./`)
exit                               # return to standard user status
cd ~/.local/bin                    # symlink the executables in your $PATH dir
ln -s /path/to/pyenv/bin/kalamine
ln -s /path/to/pyenv/bin/xkalamine

Sadly, it seems there’s no way to install keyboard layouts in ~/.config/xkb for X.Org. The system keyboard preferences will probably list user-space kayouts, but they won’t be usable on X.Org.

If you want custom keymaps on your machine, switch to Wayland (and/or fix any remaining issues preventing you from doing so) instead of hoping this will ever work on X.
