dotfiles

My cross-platform Nix configuration — a single flake that declaratively manages NixOS, WSL, and macOS (nix-darwin) machines, my dotfiles, my editor, and my theming.

Each host is named after a Shinto deity.

Systems

Inari — WSL

My day-to-day NixOS-on-WSL system (x86_64-linux), built on NixOS-WSL.

Fujin — NixOS VM

An aarch64-linux NixOS virtual machine running the GNOME desktop on Wayland, themed with Stylix.

Amaterasu — macOS

My Apple Silicon Mac (aarch64-darwin), managed with nix-darwin and nix-homebrew.

What's inside

• hjem — manages all user-level config files. Used standalone (no home-manager) to keep dotfile management fast and minimal.
• nh — wraps every NixOS/darwin rebuild. All builds and switches go through nh rather than the stock nixos-rebuild / darwin-rebuild commands.
• nvf — manages my entire Neovim configuration declaratively, shared across every host.
• Stylix — system-wide theming (Catppuccin Mocha by default; Gruvbox available).
• llm-agents — Numtide's flake packaging LLM coding agents; used here to provide Amp across every host.
• Shared package set — one common package list across all hosts plus per-host extras, covering shells, dev tooling, cloud CLIs, and more.

Note

This configuration does not use home-manager or other heavyweight modules. Dotfiles are handled by hjem standalone and the editor by nvf, deliberately keeping the module surface small to streamline build and switch times.

Usage

Clone the repo and apply the configuration for the relevant host with nh.

NixOS / WSL (Inari, Fujin):

nh os switch . -H inari   # or -H fujin

macOS (Amaterasu):

nh darwin switch . -H amaterasu
