My Nix Setup

This is my Nix configuration!

I'm using:

• nix-darwin to manage system-wide settings and applications.
• home-manager to manage user-level configuration and dotfiles.

I haven't configured any NixOS systems yet, but my goal is to keep macOS-specific configuration, such as the Emacs distribution I'm using, at the nix-darwin level, so that home-manager can be shared as much as possible accross platforms.

I'm also using Nix flakes -- I wish I knew enough about Nix to explain exactly what they are and why they're special.

Layout

I make pretty heavy use of Nix modules in this config. In every directory, default.nix is the entrypoint.

• nix-darwin default configuration lives in darwin/
• home-manager default configuration lives in home/
• host-specific overrides and functionality live in the hosts/ directory. Each host has a configuration.nix file for system config and a home.nix file for home-manager.
• dotfiles for specific applications can be found in directories under home/ alongside their home-manager configuration.
