dotfiles

My Development Setup, managed with Nix, nix-darwin, and home-manager. Works on macOS, NixOS, and standalone Linux.

Quickstart

1. Install Nix

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

2. Clone the repository

git clone git@github.com:simenandre/dotfiles.git ~/dotfiles
cd ~/dotfiles

3. Apply the configuration

macOS

On first run, bootstrap nix-darwin:

nix run nix-darwin -- switch --flake .#default

On subsequent runs:

darwin-rebuild switch --flake .#default

NixOS

Generate hardware config and rebuild:

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

Linux (standalone home-manager)

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

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