nix-config

Formerly my dotfiles repo. I went all-in on nix and absolutely love it; you should too!

Overview

This repo is managed at the top level via flake.nix, which defines configuration for:

• My personal MacBook Pro
• optimus, an old Optiplex 9020 that I picked up some years ago
• rpi4, a Raspberry Pi 4 Model B
• rpi5, a Raspberry Pi 5

Building and Deploying

# Rebuild local system
sudo nixos-rebuild switch --flake .#HOSTNAME
sudo darwin-rebuild switch --flake .#HOSTNAME

# Deploy to hosts (via ./deploy/default.nix)
nix run .#deploy-rs -- .#HOSTNAME

# Create Raspberry Pi SD card image
nix build .#images.HOSTNAME

Since I'm bound to forget how to set everything up on macOS, here's the TL;DR:

1. Install Nix via https://github.com/NixOS/nix-installer
2. Setup nix-darwin:

sudo mkdir -p /etc/nix-darwin
sudo chown $(id -nu):$(id -ng) /etc/nix-darwin
cd /etc/nix-darwin
git clone [email protected]:GregoryConrad/nix-config.git .
sudo nix run nix-darwin/master#darwin-rebuild -- switch --flake .#HOSTNAME

Tech I Use

• Nix (obviously)
• nix-darwin for configuring macOS to my liking
• home-manager for configuring my dotfiles, programs, and other config
• fish for my shell (with a modified fish-helix)
• Helix for text/code editing
• WezTerm for my terminal (with the Hack Nerd Font)
  • I love the scripting via Lua
