nix

Nix setup for my working (mac/) and gaming (pc/) computers.

Development environment

Starting from a fresh macOS computer:

1. Install Nix

Use the Determinate Systems installer — it handles the APFS volume creation, survives macOS updates, and ships an uninstaller:

curl -fsSL https://install.determinate.systems/nix | sh -s -- install

Open a new terminal afterwards so the shell picks up the Nix environment.

2. Install the development environment

Clone this repo and install the mac/ environment into the user profile:

git clone https://github.com/larry0x/nix.git ~/workspace/larry0x/nix
cd ~/workspace/larry0x/nix
nix profile add .

Among everything else, this provides the Nix tooling used to work on this repo:

• nixd: language server — completion, hover docs, and diagnostics for NixOS options
• nixfmt: the official formatter
• statix: lints for Nix anti-patterns
• deadnix: finds dead code, such as unused bindings and lambda arguments

3. Set up VSCode

Install the Nix IDE extension — the exact identifier is jnoortheen.nix-ide, beware of lookalikes — and point it at nixd in settings.json:

{
  "nix.enableLanguageServer": true,
  "nix.serverPath": "/Users/<you>/.nix-profile/bin/nixd"
}

4. Run the checks

just fmt
just lint
just test
