Initial Setup

macOS (Latte)

1. Install Nix (Determinate Systems installer recommended):

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

2. Clone this repo:

   git clone https://github.com/expede/dots.git ~/Documents/dots
   cd ~/Documents/dots/nix
   

3. Bootstrap nix-darwin (first run only):

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

4. Subsequent rebuilds use:

   darwin-rebuild switch --flake .#Latte
   

5. Set Fish as default shell:

   echo /run/current-system/sw/bin/fish | sudo tee -a /etc/shells
   chsh -s /run/current-system/sw/bin/fish
   

6. Install Doom Emacs:

   git clone --depth 1 https://github.com/doomemacs/doomemacs ~/.config/emacs
   ~/.config/emacs/bin/doom install
   doom sync
   

7. Configure 1Password SSH agent — enable in 1Password settings:

   • Settings > Developer > SSH Agent > Enable
   • Settings > Developer > CLI > Enable CLI integration

NixOS (dahlia / kielo)

1. Boot NixOS installer (minimal ISO recommended)

2. Partition disks and mount at /mnt (host-specific, see nixos/hosts/<host>/hardware.nix)

3. Clone this repo:

   nix-shell -p git
   git clone https://github.com/expede/dots.git /mnt/etc/nixos/dots
   

4. Generate hardware config (optional, compare with existing):

   nixos-generate-config --root /mnt --show-hardware-config
   

5. Install:

   cd /mnt/etc/nixos/dots/nix
   nixos-install --flake .#<hostname>
   

6. After reboot, move dots to home and rebuild:

   sudo mv /etc/nixos/dots ~/Documents/dots
   sudo chown -R $USER:users ~/Documents/dots
   cd ~/Documents/dots/nix
   sudo nixos-rebuild switch --flake .#<hostname>
   

7. Set Fish as default shell:

   chsh -s $(which fish)
   

8. Install Doom Emacs (desktop only):

   git clone --depth 1 https://github.com/doomemacs/doomemacs ~/.config/emacs
   ~/.config/emacs/bin/doom install
   doom sync
   

Templates

Rust

Scaffold a new Rust project with pinned toolchain, nightly rustfmt, and dev commands:

# From any directory
nix flake init -t github:expede/dots#rust
# Enter dev shell
nix develop

Type menu in the dev shell to see available commands:

Configuration

Edit flake.nix to customize:

# Pin Rust version
rustVersion = "1.90.0";
# Enable cross-compilation targets (darwin, linux-musl, wasm, embedded)
enableCrossTargets = true;

Included Tools

• Toolchain: cargo, clippy, rust-src, rust-std, llvm-tools-preview
• Formatting: nightly rustfmt, alejandra, taplo
• Cargo extensions: cargo-deny, cargo-expand, cargo-nextest, cargo-outdated, cargo-sort, cargo-udeps, cargo-watch
