# 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://github.com/simenandre/dotfiles.git ~/ghq/github.com/simenandre/dotfiles
cd ~/ghq/github.com/simenandre/dotfiles
```
### 3. Apply the configuration
#### macOS
On first run, bootstrap nix-darwin:
```shell
sudo nix run nix-darwin#darwin-rebuild -- switch --flake .#default
```
On subsequent runs:
```shell
sudo darwin-rebuild switch --flake .#default
```
#### 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
```
