.files

These are my dotfiles. Take anything you want, but at your own risk.

It targets a macOS systems, but some of it should work on *nix as well.

Install

  1. Use the official Nix installer for macOS: https://nixos.org/download.html#nix-install-macos

  2. Follow Flakes install steps for nix-darwin: https://github.com/LnL7/nix-darwin

  3. Another great resource is: https://nixcademy.com/2024/01/15/nix-on-macos/

  4. Get my dotfiles and link them to places where they are used:

$ git clone https://github.com/zupo/dotfiles.git ~/.dotfiles
$ ln -sv ~/.dotfiles/vscode ~/Library/Application\ Support/Code/User
$ echo 'machine niteo.cachix.org password <CACHIX AUTH TOKEN>' >> ~/.config/nix/netrc
  1. Create a secrets.nix file in your .dotfiles directory:
{
  email = "your.email@example.com";
  github = {
    token = "secret";
  };
}
  1. nix-channels are implicit and bad, so I remove them and instead use flakes to pin to exact nixpkgs commit hashes:
$ rm ~/.nix-channels
$ rm ~/.nix-defexpr/channels
$ rm ~/.nixpkgs/
  1. What to do with /etc/zshrc and /etc/zprofile?

MacOS comes with the following:

  • /etc/zprofile
  • /etc/zshrc
  • /etc/zshrc_Apple_Terminal

/etc/zprofile

I don't use it because it only provides load /usr/libexec/path_helper which is slow and not needed.

Also, LnL7/nix-darwin#532.

/etc/zshrc_Apple_Terminal

I don't use it because it only provides two features I don't need:

  • emacs support,
  • automatic history save/restore -> I prefer to use a shared history.

/etc/zshrc

I override this one with my personal settings using flake.nix

Final result

In the end, the /etc folder should be like this:

/etc ➜ ls -l z
lrwxr-xr-x  1 root  wheel  20 Sep 14 18:17 zprofile -> /etc/static/zprofile
lrwxr-xr-x  1 root  wheel  18 Apr  7  2020 zshenv -> /etc/static/zshenv
lrwxr-xr-x  1 root  wheel  17 Sep 20 11:30 zshrc -> /etc/static/zshrc

Related: LnL7/nix-darwin#193

Updating

To update to the latest release in the currently used channel, run nix flake update followed by nixre.

When a new nixpkgs channel is released, do the following:

  • update the nixpkgs.url input in flake.nix to the new channel
  • run darwin-rebuild check --flake ~/.dotfiles#zbook
  • run nixre

Troubleshooting

Problem with the SSL CA cert (path? access rights?)

If you see this error when trying to reinstall, follow https://discourse.nixos.org/t/ssl-ca-cert-error-on-macos/31171/5.
