dotfiles.nix

This repository contains a Nix file, pepicrft.nix, that I use to provision the environments from where I work.

Set it up

1. Install Nix: sh <(curl -L https://nixos.org/nix/install) --daemon.
2. Enable flakes:

mkdir -p ~/.config/nix

cat <<EOF >> ~/.config/nix/nix.conf
experimental-features = nix-command flakes
EOF

3. Restart the Nix daemon:

sudo launchctl kickstart -k system/org.nixos.nix-daemon

4. Install a tool to create a profile: nix-env -i comma.
5. Create a symlink at ~/.config/nixpkgs that points to the repository directory:

ln -s {path-to-repo} ~/.config/nixpkgs

6. Run nix run . switch in the repository directory.
7. Update iTerm's Command setting under the Profile tab to use the custom shell: ~/.nix-profile/bin/zsh
8. Update the VSCode settings to use the ZSH managed by Nix:

{
    "editor.inlineSuggest.enabled": true,
    "terminal.integrated.profiles.osx": {
        "Nix-managed ZSH": {
          "path": "/Users/pepibumur/.nix-profile/bin/zsh"
        }
    },
    "terminal.integrated.defaultProfile.windows": "Nix-managed ZSH"
}

Troubleshooting

Nix breaks on macOS updates

Add the following to the /etc/zshrc file:

if [ -e '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh' ]; then
  source '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh'
fi

Useful commands

• nix run . switch: Run it whenever we change something in the home manager configuration.
• nix flake update: Update the programs in the dependency graph and reflect the updates in the lockfile.
