The virtual device that is used internally by Karabiner-Elements triggers this issue, and a kernel panic might be caused at macOS shutdown. We confirmed that this issue has been fixed in macOS Big Sur 11.3 Beta. Please use macOS Big Sur 11.3 Beta or later versions if you are facing the kernel panic issue. Open the Karabiner-Elements Type Disable A new window with the following text will appear ‘Disable internal keyboard while external keyboards are connection’, tick the box and you will get the mac keyboard disabled. Karabiner-Elements is very unfinished/unpolished though. Like, way pre-Alpha. It's great that Karabiner is being developed, but given the number of people that are surely using MS keyboards, the situation is rather untenable. The built in key re-mapping using system preferences, at least for my mechanical keyboard, simply doesn't work. R/Karabiner: Help and discussion community for a macOS app called Karabiner Elements.

JSON::Karabiner - easy JSON code generation for Karabiner-Elements

Below is an executable perl script that generates a json file that can be read by Karabiner-Elements. You can copy and paste this code to your local machine, modify it if you wish, and execute it. Note that you must first install the JSON::Karabiner package (see the 'INSTALLATION' section below).

This script is easy to understand even if you have no experience with Perl, or any programming langauge, for that matter. But don't hesitate to file an issue if you need asssistance.

Save this code to a file on your computer and be sure to make the script executable with: Delta force for mac.

Then execute this script with:

from the same directory where this script is saved.

After this script is run, a json file called my_awesome_karabiner_mod.json should now be sitting in the assets/complex_modifications directory as long as you have Karbiner-Elements installed to the default directory (see the set_save_dir method if you don't). Now open the Karabiner-Elements app on your Mac to install the new rule.

Ready to give is try? Follow the 'INSTALLATION' instructions to get started.

Karabiner stores rules for its modifications in a file using a data format known as JSON which is painstaking to edit and create. JSON::Karabiner eases the pain by letting Perl write the JSON for you. If you aren't familar with Perl, or programming at all, don't worry. There are examples provided that you can follow so no programming knowledge is necessary. The 10 or 20 minutes you spend learning how to install and use this module will pay off in spades.

A Karabiner JSON complex modification file stores the rules for modifying the keyboard in a data structure called 'manipulators.' Therefore, most of methods you write will add data to the manipulator data structure. JSON::Karabiner can then write the JSON to a file and then you can load the rules you generate with your script with the Kabrabiner-Elements program.

Below are descriptions of the methods used on manipulators.

for adding the from/to actions to the manipulator

for adding manipulator conditions

for adding maniplator parameters

for adding a description to the manipulator

After you run a add_action or add_condition method, you will need to run additional methods that will be applied to the last action or condition you added.

It will be very helpful if you have a basic familiarity with the Karabiner manipulator definition to gain an understanding of which methods to run. See the Karabiner complex_modification manipulator documentation for more information.

DSL Interface

As of version 0.011, JSON::Karabiner moved to a DSL (domain specific language) interface to make writing scripts even easier. Please see the 'SYNOPSIS' for an example of how to use the DSL. Note that the older object-oriented interface, though currently deprecated and undocumented, is still fully functional (or should be, in theory).

How to Use the DSL Interface

There are two parts to a DSL inteface: the method and the list of arguments you are passing to the method. You can think of the method as the action you want to take and the arguments as the data 'nouns' you want to store or process.

Methods that add data to the manipulator begin with add_ followed by a string of characters that corresponds to properties outlined in the Karabiner documentation. For example, to add a key_code property, you write:

Here, the action is add_key_code and the data is the character 't'. Note that the method call must end in a semicolon. Each argument you pass must be surrounded by apostrophes. Or, if you want to avoid the pain of having to type apostrophers, you can use Perl's qw function:

It bears repeating that methods that apply to actions (or condtions) are automatically assigned to the most recent action (or condition) that was created. In other words, if your have:

The key code will be added to the from action. If you wish apply it to the to action, simply move the add_key_code line immediately after the to action. This same rule applies for condtions as well as actions. Any method that adds data to a condtion will get added to the last condition created.

List of Methods for Actions

The following methods apply to actions (e.g. from, to, to_if_alone etc.)

From methods

The following methods are for the from action:

add_any

add_consumer_key_code

add_key_code

add_mandatory_modifiers

add_optional_modifiers

add_pointing_button

add_simultaneous

add_simultaneous_options

To methods

The following methods are for the to action (includes to_if_alone, to_if_held_downto_after_key_up, to_delayed_if_invoked, to_delayed_if_canceled):

add_consumer_key_code

add_key_code

add_modifiers

add_mouse_key

add_pointing_button

add_select_input_source

add_set_variable

add_shell_command

List of Methods for Conditions

The following methods will add data to the most recently created condition in the script.

add_bundle_identifiers

add_description

add_file_path

add_identifier

add_input_source

add_keyboard_types

add_value

add_variable

For further details on each these methods, including the arguments they take, please see the appropriate perl doc page:

conditions

Multiple manipulators

The DSL interface makes it easy to include multiple manipulator in a single rule. Follow this pattern:

All the manipulators will be added to the same file name.

Notice that you can group multiple manipulators under the same rule name. A new manipulator that is added will inherit the rule name of the last rule name set with the set_rule_name method.

Writing to the JSON file

As shown in the example above, a write_file is called to write out your JSON file.

set_filename($filename)

This method override the default setting for the name of the .json file where the script will save the generated json code. By default, the .json file will share the same file prefix of your script name. So if your script is named my_script.pl, the json file will be named my_script.json.

Example usage:

If you do not provide the .json file extension, it will be automatically attached for you.

set_save_dir($directory_path)

This mehtod is only needed if you have Karabiner-Elements installed in a non-standard directory and you need to override the default of ~/.config/karabiner/assets/complex_modifications.

Example usage:

set_title($rule_title)

This sets the rule title your manipulators are grouped under. It is used by Karabiner-Elements to organize your rules in the graphical user interface.

Example usage:

set_rule_name($rule_name)

Manipulators are assinged to individual rule names. These rule names, or descritpions, are grouped under the rule title. You can have many manipulators assigned to one rule name. Newly create manipulators are assigned to the last rule name set with the set_rule_method.

Example usage:

new_manipulator()

Example usage:

This method creates a new manipulator. It must be called before adding actions, conditions and parameters.

add_action($type)

There are seven different types of actions you can add:

The most frequently used actions are the first four listed above. You must create a from action to your manipulator. The from action contains the keystrokes you want to modify. The other to actions describe what the from keystroke actions will be changed into. See the Karabiner documentation for more information on these actions.

Once these actions are created, you may run methods to that add additional data to them to modify their behavior. Consult the documentation for the different actions for a listing and description of those methods: Visio free for mac.

add_condition($type)

Conditions make the modification conditional upon some other bit of data. You can add the following types of conditions:

Once the conditions are created, you can add data with additional methods. See the additional documenation for these methods and the arguments they accept:

Consult the Karabiner documentation to understand how they modifty the behavior of the actions.

add_parameter($name, $value)

Parameters are used by Karabiner to change various timing aspects of the actions. Four different parameters may be set:

See the Karabiner documentation for more details.

add_description($description)

Adds a description to the manipulator data structure:

This description is not visible inside Karabiner-Elements apps.

write_file([$title], [$filename])

This method writes all the manipulator objects out to a .json file.

Example usage:

This method will overwrite pre-existing files with the same name without warning, so be sure the file name is unique if you don't want this to happen.

The title argument is not required if it has already been set with the set_title method, otherwise it is required. The $filename argument is always optional and will default to the what was set with set_filename or, if that method wasn't used, than the filename will inherit the prefix from the name of the script. The .json extension is required for this method and cannot be omitted.

This software is written in Perl and bundled as a package called JSON::Karabiner. If you are not familiar with installing Perl packages, don't worry. Just follow this simple two-step process:

Step 1: Ensure the cpanm command is installed:

Run the following command from a terminal window:

If the terminal reponds with the path to cpanm, proceed to Step 2.

If the cpanm command is not installed, copy and paste one of the following three commands into your terminal window to install it:

If you are unsure what the best option is for installing cpanm, consult its documentation for more help.

Step 2: Install the JSON::Karabiner package

Now issue the following comamdn to install the software:

After issuing the cpanm command above, you should see a success message. If so, you can start using cpanm JSON::Karabiner and start using it in local Perl scripts you write. If you get errors about lack of permissions, try running:

If you still get weird errors, it may be a bug. Please report your issue to the issue queue.

Other install methods

This module can also be installed using the older cpan command that is already on your Mac. See how to install CPAN modules for more information.

version 0.018

This module is currently in alpha release and is actively supported and maintained. Suggestion for improvement are welcome. It is known to generate valid JSON that allow Karabiner to import rules from the file generated for at least simple cases and probably more advanced cases as well.

Many improvements are in the works. Flash for mac os. Please watch us on GitHub.

Perldoc

You can find documentation for this module with the perldoc command.

Source Code

Karabiner Elements For Windows

The code is open to the world, and available for you to hack on. Please feel free to browse it and play with it, or whatever. If you want to contribute patches, please send me a diff or prod me to pull from your repository :)

Though this software is still in an alpha state, it should be able to generate code for any property with the exception of the to_after_key_up key/value use for the simultaneous options behavior due to uncertainty in how this should be implemented. If you need this feature, generate your json code using this script as you normally would and then manually edit it to insert the necessary json code.
