🌲🌴 import-tree 🎄🌳

Recursively import Nix modules from a directory, with a simple, extensible API.

Features

🌳 Works with NixOS, nix-darwin, home-manager, flake-parts, NixVim, etc.
🌲 Callable as a deps-free Flake or nix lib.
🌴 Sensible defaults and configurable behaviour.
🌵 Chain .filter, .match, .map for precise file selection.
🎄 Extensible: .addAPI to create domain-specific instances.
🌿 Built to enable the Dendritic Pattern on both stable/unstable Nix.
🌱 Growing community adoption

Quick Start

The following examples show how to import all module files. By default, paths having /_ are ignored. See API documentation for advanced usage.

Dendritic flake-parts

# flake.nix
{
  inputs.import-tree.url = "github:denful/import-tree";
  inputs.flake-parts.url = "github:hercules-ci/flake-parts";

  outputs = inputs: inputs.flake-parts.lib.mkFlake { inherit inputs; }
   (inputs.import-tree ./modules);
}

Dendritic flake without flake-parts

# flake.nix
{
  inputs.import-tree.url = "github:denful/import-tree";
  inputs.nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";

  outputs = inputs:
   (inputs.nixpkgs.lib.evalModules {
      specialArgs.inputs = inputs;
      modules = [ (inputs.import-tree ./modules)  ];
   }).config;
}

Dendritic Nix (non-flakes, stable Nix)

This example uses with-inputs to provide flake-file inputs from npins sources.

# default.nix
let
  sources = import ./npins;
  with-inputs = import sources.with-inputs sources {};
  outputs = inputs:
   (inputs.nixpkgs.lib.evalModules {
      specialArgs.inputs = inputs;
      modules = [ (inputs.import-tree ./modules)  ];
   }).config;
in
with-inputs outputs
