Dots

This repo is a Nix flake that manages most of my setup on macOS and fully manages machines I have that run NixOS as their operating system.

Flake structure

The Nix bits are driven by flake.nix which pulls in things under modules/. Initial support is for both x86 macOS and NixOS. The flake is structured like so:

• description: a human readable description of this flake
• inputs: all the places things are pulled from
• outputs:
  • all the outputs from the inputs
  • a let ... in block that contains:
    • darwinHostConfig which takes 3 params and pulls in all the things needed to use Nix on a macOS host
    • nixosHostConfig which takes 3 params and pulls in all the things needed to configure a NixOS host
  • the body of outputs that contains:
    • darwinConfigurations contains an entry for each macOS host set to the results of a call to darwinHostConfig with values for each of the required parameters
    • nixosConfigurations contains an entry for each nixOS host set to the results of a call to nixosHostConfig with values for each of the required parameters

The parameters on darwinHostConfig & nixosHostConfig are:

• system: the system definition to use for nixpkgs
• hostname: the hostname of the machine being configured
• username: the username being configured on the host (all code currently assumes there is a single human user managed by Nix)

Repo structure

The Nix stuff is structured like so, at least for now:

Historical bits

This repo historically contained my dot files. Historically symlinked files are still in link/. Most all the other old stuff is now tucked away under legacy/ to get it out of the way until I decide what is and isn't needed.

Adding a new macOS host

1. clone this repo
2. add entry to flake.nix
3. add file at modules/home-manager/hosts/< hostname >/< username >.nix
4. add file at modules/hosts/< system >/< hostname >/default.nix
   • run brew leaves and look for things installed from taps you don't want any more
   • uninstall the program and the tap if not adding it to nix
5. run macOS installer from https://determinate.systems/posts/graphical-nix-installer
6. run nix run nix-darwin -- check --flake ~/repos/dots
7. run sudo mv /etc/shells{,.before-nix-darwin}
8. run sudo mv /etc/zshenv{,.before-nix-darwin}
9. Note that you may also have to move or remove ~/.zshrc
10. Run nix run nix-darwin -- switch --flake ~/repos/dots
    1. first (or several) run(s) through homebrew may well fail due to previously installed casks in /Applications. You may have to run brew with --force to fix this
    2. you may have to run brew multiple times to fix things
    3. in Settings > Privacy & Security > App Management you will need to allow iTerm
    4. Note: ensure firefox-profile-switcher-connector is linked:
11. After the nix command finally works, open a new shell and it should have all the nixified settings in it.
12. Go into iTerm2 and use the Hack Nerd Mono font so that the prompt and other things look right. You will likely also want to adjust the size of the font.

Now that that is done, setup Atuin:

atuin import auto
read -s ak
read -s ap
atuin login --key $ak --password $ap --username gene
