json2nix

A json to nix converter written in Haskell. You can use this easily with a flake. Unformatted json is also supported.

Usage

If you have something like this:

{
    "name": "Alice",
    "age": 21,
    "length_in_meters": 1.8,
    "best_friends": [
        {
            "name": "bob",
            "age": 19,
        },
        {
            "name": "Sem",
            "age": 19,
        }
    ],
    "favorite_movie": null,
    "(some)%wild;key": 5,
    "1": [],
    "2": []
}

And you want something like this:

{
  name = "Alice";
  age = 21;
  length_in_meters = 1.8;
  best_friends = [
    {
      name = "bob";
      age = 19;
    }
    {
      name = "Sem";
      age = 19;
    }
  ];
  favorite_movie = null;
  "(some)%wild;key" = 5;
  "1" = [];
  "2" = [];
}

You can do so by enabling nix flakes and run the following command in your shell:

nix run github:sempruijs/json2nix

This will install the required tools. json2nix will ask two questions:

1. Choose a file path. This could be something like: config.json.

2. Choose a file name for the new nix file. You can type something or hit enter for the suggestion. This would be something like: config.nix
