den - an aspect-oriented approach to Dendritic Nix configurations.

den and vic's dendritic libs made for you with Love++ and AI--. If you like my work, consider sponsoring

Dendritic: each module configures same concern over different Nix classes. Create DRY & class-generic modules. Parametric over host/home/user. Share aspects across systems & repos. Context-aware dependencies: user/host contributions. Routable configurations. Custom factories for any Nix class. Use stable/unstable channels per config. Freeform host/user/home schemas (no specialArgs). Multi-platform, multi-tenant hosts. Batteries: Opt-in, replaceable aspects. Opt-in <angle/brackets> aspect resolution. Templates tested along examples. Concepts documented. Need more batteries? See vic/denful. ❄️ Try it now! Launch our template VM: nix run github:vic/den Or, initialize a project: nix flake init -t github:vic/den nix flake update den nix run .#vm Real-world examples for inspiration vic/vix belsanti.xyz/nixconfig GitHub Search. Available templates default batteries-included layout. minimal truly minimalistic start. examples tests for all features. bogus reproduce and report bugs.

🏠 Define Hosts, Users & Homes concisely. See schema in _types.nix. # modules/hosts.nix { # same home-manager vic configuration # over laptop, macbook and standalone-hm den.hosts.x86_64-linux.lap.users.vic = {}; den.hosts.aarch64-darwin.mac.users.vic = {}; den.homes.aarch64-darwin.vic = {}; } $ nixos-rebuild switch --flake .#lap $ darwin-rebuild switch --flake .#mac $ home-manager switch --flake .#vic 🧩 Aspect-oriented incremental features. (example) Any module can contribute configurations to aspects. # modules/my-laptop.nix { den, inputs, ... }: { # Example: enhance the my-laptop aspect. # This can be done from any file, multiple times. den.aspects.my-laptop = { # this aspect includes configurations # available from other aspects includes = [ # your own parametric aspects den.aspects.workplace-vpn # den's opt-in batteries includes. den.provides.home-manager ]; # any file can contribute to this aspect, so # best practice is to keep concerns separated, # each on their own file, instead of having huge # modules in a single file: # any NixOS configuration nixos = { # A nixos class module, see NixOS options. # import third-party NixOS modules imports = [ inputs.disko.nixosModules.disko ]; disko.devices = { /* ... */ }; }; # any nix-darwin configuration darwin = { # import third-party Darwin modules imports = [ inputs.nix-homebrew.darwinModules.nix-homebrew ]; nix-homebrew.enableRosetta = true; }; # For all users of my-laptop homeManager.programs.vim.enable = true; }; } # modules/vic.nix { den, ... }: { den.aspects.vic = { homeManager = { /* ... */ }; # User contribs to host nixos.users.users = { vic.description = "oeiuwq"; }; includes = [ den.aspects.tiling-wm den._.primary-user ]; }; }

You are done! You know everything to start creating configurations with den.
