Project Layout

Instead of configuring everything in flake.nix, Conflake can derive outputs according to your project directory structure.

Considering the following directory structure, from examples/demo:

examples/demo/
├── .editorconfig
├── flake.nix
└── nix/
    ├── darwin/
    │   └── hostname.nix
    ├── darwinModules/
    │   └── default.nix
    ├── home/
    │   └── username.nix
    ├── homeModules/
    │   └── default.nix
    ├── nixos/
    │   └── hostname.nix
    ├── nixosModules/
    │   └── default.nix
    ├── packages/
    │   └── default.nix
    └── templates/
        └── default/
            └── flake.nix

It will result a flake output like:

nix flake show
