How to disable formatter?

[yajo]

I use both nixd and nil LSPs.

When I save a Nix file, it gets formatted with (I guess) nixfmt.

How can I disable that? All my projects use pre-commit for formatting (and alejandra fwiw).

Thanks.

You just need to turn "format_on_save" to off in settings.json.

"languages": {
  "Nix": {
    "format_on_save": "off",
  },
}
