# dotfiles

My Development Setup, managed with [Nix](https://nixos.org), [nix-darwin](https://github.com/LnL7/nix-darwin), and [home-manager](https://github.com/nix-community/home-manager). Works on macOS, NixOS, and standalone Linux.

## Quickstart

Setting up a new machine? Follow [INSTALL.md](INSTALL.md) — it covers the
prerequisites (Homebrew, App Store, 1Password SSH agent) that the commands below
assume are already in place.

### 1. Install Determinate Nix

```shell
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install --determinate
```

### 2. Clone the repository

```shell
git clone https://simenandre.no/dotfiles.git ~/ghq/simenandre.no/dotfiles
cd ~/ghq/simenandre.no/dotfiles
```

### 3. Apply the configuration

#### macOS

Configurations are per-machine — `makkie` (user `simenandre`) and `default`
(user `cobraz`). Substitute the one you are on.

On first run, bootstrap nix-darwin:

```shell
sudo nix run nix-darwin#darwin-rebuild -- switch --flake .#makkie
```

On subsequent runs:

```shell
sudo darwin-rebuild switch --flake .#makkie
```

#### NixOS

Generate hardware config and rebuild:

```shell
sudo nixos-generate-config --show-hardware-config > hosts/nixbox/hardware-configuration.nix
sudo nixos-rebuild switch --flake .#nixbox
```

#### Linux (standalone home-manager)

```shell
# x86_64
home-manager switch --flake .#simenandre

# aarch64
home-manager switch --flake .#simenandre@aarch64-linux
```
