NixOS Dotfiles

Combined NixOS, Darwin and Home Manager flake for various hosts.

Workstation-first development environment

This flake is for day-to-day workstation and development use, so it is not strictly "pure Nix" everywhere. Some tools are intentionally allowed to manage their own fast-moving state when that makes the machine more useful.

Non-Nix-managed patterns used on purpose:

• nix-ld is enabled on Linux (system/catharsis/configuration.nix) to support developer tooling that expects dynamic linking outside the Nix store. The same pattern may be enabled on Darwin if it proves useful there.
• npm uses the Nix-provided Node.js runtime, but global npm packages are installed under ~/.npm (home/dev/npm.nix). This keeps CLIs such as Claude, Codex, and similar tools easy to update without waiting for nixpkgs.
• Neovim is a LazyVim setup in home/nvim, linked into ~/.config/nvim via an out-of-store Home Manager symlink (home/dev/nvim_lazyvim.nix). LazyVim, lazy-lock.json, and Mason-managed tools can then evolve like a normal editor config, including tooling that may live outside the Nix store.
