This repo contains my Nix configs for macOS and Linux and by extension, configuration for most tools/programs I use, at least in the terminal.

I'm continuously tweaking/improving my setup, trying to find ways to make more of my configuration declarative, and I like experimenting with bleeding edge updates/features, so this repo sees a lot of changes. I do try to ensure that master always builds and doesn't have any bad bugs (at least in my workflow), and keep the code fairly well documented.

Feel free to file an issue or start a discussion if you find a bug, or think something is broken, or think I'm doing something in a dumb/clumsy way and have a suggestion for a more elegant alternative, or try to crib something from my config but just can't get it working, or are looking at my config and think to yourself "does this guy know about X, cause I bet he'd be into it", or have some other type of feedback/comment. (Issues, are better for things that are actually issues, while discussions are better for ideas, questions, etc.)

I make no promises that I'll respond quickly, or fix the bug (especially if I'm not experiencing it), or whatever, but you definitely shouldn't feel like you're imposing in any way, and I probably will respond within a few days.

Below, I've highlighted stuff that I'm particularly happy with or think others might find helpful/useful.

In no particular order:

• Flakes!
  • All external dependencies managed through flakes for easy updating.
  • Outputs for nix-darwin macOS system configurations (using home-manager as a nix-darwin module) and a home-manager user configuration for Linux.
  • A function to simplify making nix-darwin system configurations (with home-manager integration), lib.mkDarwinSystem.
  • darwinModules output for nix-darwin modules with additional functionality and prepackaged configuration, including:
    • users-primaryUser that provides users.primaryUsers.{username,fullName,email,nixConfigDirectory} options, which allows specifying this information one time by setting these options and then referencing their values when setting other options.
  • homeManagerModules output for home-manager modules with additional functionality and prepackaged configuration, including:
    • [home-user-info], that provides the same options as the my nix-darwin module users-primaryUsers above under home.user-info. See examples of it in use in home/git.nix, home/neovim.nix.
    • colors which is a WIP module used to define colorschemes. See home/colors.nix, for an example of how to define a colorscheme.
    • programs-neovim-extras that provides programs.neovim.extras.{defaultEditor,nvrAliases,termBufferAutoChangeDir} options.
    • programs-kitty-extras that provides a,
      • programs.kitty.extras.colors option to configure a light and dark colorscheme, which when used also adds term-light, term-dark, and term-background scripts to home.packages to easily switch between them; and a
      • programs.kitty.extras.useSymbolsFromNerdFont option to use symbols from a NerdFont while using any font with Kitty.
    • malo-git-aliases
    • malo-gh-aliases
    • malo-startship-symbols that provides predefined configuration of symbols for Starship prompt using NerdFont symbols.
  • Support for non-flake compatible versions of Nix and legacy workflows through flake-compat:
    • default.nix, allows traditional Nix commands like nix-build to operate on the flake inputs/outputs.
• Support for Macs with Apple Silicon including ability to easily overlay in x86 version of packages, when they don't build on ARM. Search pkgs-x86 in flake.nix and see nix.settings.extra-platforms in darwin/bootstrap.nix for details.
• A GitHub workflow that builds the my macOS system nix-darwin config and home-manager Linux user config, and updates a Cachix cache. Also, once a week it updates all the flake inputs before building, and if the build succeeds, it commits the updated flake.lock file.
• Git config with a bunch of handy aliases and better diffs using delta.
• A slick Neovim config in Lua. See also neovim.nix.
• Unified colorscheme (based on Solarized) with light and dark variant for Kitty terminal, Fish shell, Neovim, and other tools, where toggling between light and dark can be done for all of them simultaneously by calling a Fish function. This is achieved by:
  • using the colors module mentioned above;
  • using my programs-kitty-extras home-manager module (see above);
  • using a self-made WIP Solarized based colorscheme with Neovim; and
  • a Fish shell config, which provides a toggle-background function (and an alias tb) which toggles a universal environment variable ($term_background) between the values "light" and "dark", along with set-shell-colors function which trigger automatically when $term_background changes.
• A nice shell prompt config for Fish using Starship.
