Dotfiles

Nix-based dotfiles configuration using Home Manager and nix-darwin for macOS system management.

Prerequisites

1. Install Nix

Install the Nix package manager with flakes support:

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

After installation, restart your terminal or source the environment:

source /nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh

2. Enable Flakes

If not already enabled, add flake support to /etc/nix/nix.custom.conf:

experimental-features = nix-command flakes  

3. Install Git

Since Home Manager will manage Git, install it temporarily to clone the repository. This will only install git for the current shell. Once exited, git will no longer be in your PATH.

nix-shell -p git

4. Clone Repository

git clone https://github.com/yourusername/dotfiles.git
cd dotfiles

Installation

1. Apply Home Manager Configuration:

# Apply Home Manager configuration
nix run .#homeConfigurations.jonerickson.activationPackage

2. Apply System Configuration (Darwin):

# Make sure command line tools have been installed first
xcode-select --install

nix build .#darwinConfigurations.jonerickson.system
sudo ./result/sw/bin/darwin-rebuild activate

Important: Make sure all changes are committed before building: git add -A && git commit -m "Initial setup"

3. Setup Secrets Management (Optional)

If you need to manage secrets, follow these steps:

Option A: Fresh Install (Generate New Key)

1. Generate a new age encryption key:

mkdir -p ~/.config/sops/ageage-keygen > ~/.config/sops/age/keys.txt

2. Get your public key and update configuration:

age-keygen -y ~/.config/sops/age/keys.txt

3. Update .sops.yaml with your new public key (replace the existing key)

4. Create and encrypt your secrets file:

# Create unencrypted secrets file  
cp home/secrets.yaml.example home/secrets.yaml  # if example exists  
# OR manually create home/secrets.yaml with your secrets  
  
# Encrypt the file  
sops -e -i home/secrets.yaml  
  
# Commit the encrypted file  
git add home/secrets.yaml .sops.yaml  
git commit -m "Add encrypted secrets"  

Option B: Migrating from Existing Setup

1. Copy your existing age key from your old machine:

mkdir -p ~/.config/sops/age
# Copy your existing keys.txt file to ~/.config/sops/age/keys.txt

2. The existing .sops.yaml and encrypted home/secrets.yaml should already work with your key

3. Test decryption:

sops -d home/secrets.yaml

Secrets File Structure

The home/secrets.yaml file should contain:

composer:
  whizzy-username: your-username
  whizzy-password: your-password
  filament-username: your-username
  filament-password: your-password
  spark-username: your-username
  spark-password: your-password
  github-token: your-github-token  

Note: Do not commit an unencrypted version home/secrets.yaml to your VCS. You should only commit the encrypted version of your secrets.

Subsequent Updates

Regular User Configuration Updates

After making changes to the user configuration:

git add -A
git commit -m "Update user configuration"
nix run .#homeConfigurations.jonerickson.activationPackage

Regular System Configuration Updates

After making changes to the system configuration:

git add -A
git commit -m "Update system configuration"
nix build .#darwinConfigurations.jonerickson.system
sudo ./result/sw/bin/darwin-rebuild activate

Updating Secrets

To update encrypted secrets:

# Edit secrets (will decrypt, open editor, then re-encrypt)  
sops home/secrets.yaml  
  
# Or manually decrypt, edit, and re-encrypt  
sops -d home/secrets.yaml > temp_secrets.yaml  

# Edit temp_secrets.yaml  
sops -e -i temp_secrets.yaml  
mv temp_secrets.yaml home/secrets.yaml  
  
# Commit changes  
git add home/secrets.yaml  
git commit -m "Update secrets"
