Help with complex modification

[Jendker]

Can someone help me write this complex modification in EDN?

{
    "description": "Fn change language",
    "manipulators": [
        {
            "from": {
                "key_code": "fn"
            },
            "to": [
                {
                    "key_code": "fn",
                    "lazy": true
                }
            ],
            "to_if_alone": [
                {
                    "apple_vendor_keyboard_key_code": "language"
                }
            ],
            "type": "basic"
        }
    ]
}

I have my full config in EDN and am just missing this one. It's a bit more difficult than the stuff I have been doing so far and I wasn't able to get the EDN -> karabiner.json mapping to work after my own attempts.

I found a working solution based on the great dotfiles https://github.com/yqrashawn/yqdotfiles/blob/61dae1e5363a37e01dfca779c64c99639a11b39f/.config/karabiner.edn :)

  {:des "Fn change language" :rules [
                             {:from {:key_code :fn}
                              :to [{:key_code :fn :lazy true}]
                              :to_if_alone [{:apple_vendor_keyboard_key_code :language}]
                              :type :basic}
                             ]}

Maybe it helps someone.
