# `null2264`'s Nix Setup

You need to install Nix before following this guide: `sh <(curl -L https://nixos.org/nix/install)` and symlink this dir to `~/.config/nix`

## Setup

### macOS

Nix in macOS is handled by [nix-darwin](https://github.com/LnL7/nix-darwin).

#### Initial

This is done because nix-darwin commands is not yet added to PATH, should be a one-time thing

```zsh
nix-env -iA nixpkgs.git
# Run `sudo chown $USER /nix/var/nix/profiles/per-user/$USER` if that returns error

nix build .#darwinConfigurations.<host>.system

./result/sw/bin/darwin-rebuild switch --flake .#<host>
# or
nix run nix-darwin -- switch --flake .#<host>
```

#### Rebuild

After initial setup, you should now be able to use the command directly:

```sh
darwin-rebuild build --flake .  # or you can specify the hostname with `--flake . #<hostname>`

# or if you're feeling lucky

darwin-rebuild switch --flake .
```

### Other

Nix in non-NixOS Linux is handled by [system-manager](https://github.com/numtide/system-manager).

### Home

This is for per-user setup. Instead of managing the entire system, you're
managing one user at a time. This is handled by
[home-manager](https://github.com/nix-community/home-manager)

#### Rebuild

```sh
home-manager build --flake .  # or you can specify the user with `--flake . #<username>@<hostname>`

# or if you're feeling lucky

home-manager switch --flake .
```
