Dotfiles

Uses:

• Nix for dotfiles, CLI tool and general system config, via:
  • Home Manager
  • nix-darwin
• Homebrew for GUI apps
• Chezmoi for private or host-specific config

One-time Setup

Note

At one point these were automated, but they only need to be done once when setting up a new computer, and frequently change with the OS version, so it's easier to just do them manually

1. Install Determinate Nix (see website)
2. Install Homebrew (see website)

Now run:

# Assuming that $PWD is this repo
$ sudo nix run .#rebuild -- switch --flake $PWD#<hostname>

# if that doesn't work, try:
$ sudo nix run --inputs-from $PWD nix-darwin#darwin-rebuild -- switch --flake $PWD#<hostname>

Next steps:

1. Create SSH key (see GH's docs for current recommendation):
   1. Add to GitHub
   2. Add to SSH agent (again, see GH's docs)
2. Remap Caps Lock to Ctrl on all keyboards (via System Settings)

# Set computer name
$ read '?Hostname: ' name; for var in ComputerName HostName LocalHostName; do sudo scutil --set "$var" "$name"; done

# Set default location for `darwin-rebuild` `--flake` option
$ sudo ln -ivs ~/src/dotfiles/flake.nix /etc/nix-darwin/flake.nix

# Setup Chezmoi
$ ln -ivs ~/src/dotfiles ~/.local/share/chezmoi
$ mkdir -p ~/.config/chezmoi
$ ln -ivs ~/src/dotfiles/hosts/chezmoi/$(hostname).toml ~/.config/chezmoi/chezmoi.toml

# Run Chezmoi
$ chezmoi diff
# (check output, then)
$ chezmoi apply
