Kalamine

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

Install

To install kalamine, all you need is a Python 3.8+ environment and pip:

.. code-block:: bash

# to install kalamine
python3 -m pip install --user kalamine

# to upgrade kalamine
python3 -m pip install --user --upgrade kalamine

# to uninstall kalamine
python3 -m pip uninstall --user kalamine

However, we recommend using pipx_ rather than pip as it provides pyenv containment, which is a much saner approach and is becoming mandatory on many operating systems (e.g. Arch Linux). It is even simpler from a user perspective:

.. code-block:: bash

# to install kalamine
pipx install kalamine

# to upgrade kalamine
pipx upgrade kalamine

# to uninstall kalamine
pipx uninstall kalamine

Arch Linux users may use the AUR package_:

.. code-block:: bash

yay -S kalamine-git

Developer-specific installation instructions can be found in the CONTRIBUTING.md_ file.

.. _pipx: https://pipx.pypa.io .. _AUR package: https://aur.archlinux.org/packages/kalamine-git .. _CONTRIBUTING.md: https://github.com/OneDeadKey/kalamine/blob/main/CONTRIBUTING.md

Building Distributable Layouts

Create a keyboard layout with kalamine new:

.. code-block:: bash

kalamine new layout.toml # basic layout kalamine new layout.toml --altgr # layout with an AltGr layer kalamine new layout.toml --1dk # layout with a custom dead key kalamine new layout.toml --geometry ERGO # apply an ortholinear geometry

Edit this layout with your preferred text editor:

• the user guide_ is available at the end of the *.toml file
• the layout can be rendered and emulated with kalamine watch (see next section)

.. _user guide: https://github.com/OneDeadKey/kalamine/tree/master/docs

Build your layout:

.. code-block:: bash

kalamine build layout.toml

Get all distributable keyboard drivers:

.. code-block:: bash

dist/
  ├─ layout.ahk            # Windows (user)
  ├─ layout.klc            # Windows (admin)
  ├─ layout.keylayout      # macOS
  ├─ layout.xkb_keymap     # Linux (user)
  ├─ layout.xkb_symbols    # Linux (root)
  ├─ layout.json           # web
  └─ layout.svg

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

.. code-block:: bash

kalamine build layout.toml --out layout.xkb_symbols

Emulating Layouts

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

.. code-block:: bash

$ kalamine watch layout.toml
Server started: http://localhost:1664

Check your browser, type in the input area, test your layout. Changes on your TOML file are auto-detected and reloaded automatically.

.. image:: watch.png

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

Using Distributable Layouts

Windows (user): *.ahk

* download the `AHK 1.1 archive`_
* load the ``*.ahk`` script with it.

The keyboard layout appears in the notification area. It can be enabled/disabled by pressing both Alt keys.

.. _`AHK 1.1 archive`: https://www.autohotkey.com/download/ahk.zip

You may also use Ahk2Exe to turn your ``*.ahk`` script into an executable file. The ``U32 Unicode 32-bit.bin`` setting seems to work fine.


Windows (admin): ``*.klc``

Note: this applies only if you want to use the *.klc file. A better approach is to use wkalamine (see below).

• 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;
• :strong:restart your session, even if Windows doesn’t ask you to.

The keyboard layout appears in the language bar.

Note: in some cases, custom dead keys may not be supported any more by MSKLC on Windows 10/11. KbdEdit works fine, but its installers are not signed. WKalamine works fine as well (see below) and its installers are signed.

Basic developer info available in Kalamine’s KLC documentation page_.

.. _MSKLC: https://www.microsoft.com/en-us/download/details.aspx?id=102134 .. _KbdEdit: http://www.kbdedit.com/ .. _KLC documentation page: https://github.com/OneDeadKey/kalamine/tree/master/docs/klc.md

macOS: *.keylayout

* 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): ``*.xkb_symbols``

:strong:This is by far the simplest method to install a custom keyboard layout on Linux.

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

.. code-block:: bash

sudo cp layout.xkb_symbols ${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:

.. code-block:: bash

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:

.. code-block:: properties

input type:keyboard {
    xkb_layout "custom"
}

Linux (user): *.xkb_keymap

``*.xkb_keymap`` 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``:

.. code-block:: bash

    xkbcomp -w10 layout.xkb_keymap $DISPLAY

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

.. code-block:: bash

    setxkbmap us

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

.. code-block:: properties

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


WKalamine
--------------------------------------------------------------------------------

``wkalamine`` is a Windows-specific CLI tool to create MSKLC_ setup packages.

This is kind of a hack, but it provides an automatic way to build setup packages on Windows and more importantly, these setup packages overcome MSKLC’s limitations regarding chained dead keys and AltGr+Space combos.

It is done by generating the C layout file, and tricking MSKLC to use it by setting it as read-only before.

Make sure MSKLC is installed and build your installer:

.. code-block:: bash

    wkalamine build layout.toml

and you should get a ``[layout]\setup.exe`` executable to install the layout.

Remember to log out and log back in to apply the changes.


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 *most* Wayland environments, keyboard layouts can be installed in user-space:

.. code-block:: bash

    # 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:

.. code-block:: properties

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

Note: some desktops like KDE Plasma, despite using Wayland, do not support
keyboards layouts in ``~/.config:xkb`` out of the box. In such cases, using
``xkalamine`` as ``sudo`` is required, as described below.


X.Org (root)
````````````

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

.. code-block:: bash

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

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

.. code-block:: bash

    # Install a YAML/TOML keyboard layout into /usr/share/X11/xkb
    sudo env "PATH=$PATH" xkalamine install layout.toml

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

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

.. code-block:: bash

   setxkbmap us -variant prog

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

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.
