Nix

Installation

See instructions here.

Toolchain

Formatting

Use either one of these two formatters:

• nixfmt (official formatter in nixpkgs)
• alejandra

Linting

Language Server Setup

It is very wise to use nixd as the language server for Nix files together

Settings for nixd

The following LSP settings will make autocomplete nixpkgs:

{
  nixpkgs = {
    expr = "import <nixpkgs> { }",
  },
  formatting = { command = "nixfmt" },
  options = {
  }
}

If you want to autocomplete also on your NixOS system add the following:

  options = {
    nixos = {
      expr = string.format(
        '(builtins.getFlake "<path-to-your-flake>").nixosConfiguration.<your-system-name>',
        p
      ),
    },
  }

info

These settings are LSP configuration settings which can be applied in any editor setup which supports LSPs (e.g. nvim, code).
