ndg is a way to automatically generate an HTML document containing all the options you use in any set of modules.

This flake exposes a package (packages.<system>.ndg-builder a.k.a. packages.<system>.default), as well as an overlay (overlays.default) to allow accessing ndg-builder in another nixpkgs instance.

You can override the exposed package with the following options:

• rawModules: a list of modules containing options to document. For example:

[
  {
    options.hello = lib.mkOption {
      default = "world";
      description = "Example option.";
      type = lib.types.str;
    };
  }
]

• specialArgs: the specialArgs to pass through to the lib.evalModules call.
• evaluatedModules: the result of lib.evalModules applied to a list of modules containing some options to document. For example:

lib.evalModules {
  modules = [
    {
      options.hello = lib.mkOption {
        default = "world";
        description = "Example option.";
        type = lib.types.str;
      };
    }
  ];
}

This includes anything that uses lib.evalModules underneath, such as a NixOS, Home Manager, or Nix-Darwin configuration. For example, in the context of a flake:

self.nixosConfigurations.myHost

• title: the title of your documentation page
• templatePath: path to a pandoc template
• styleSheetPath: path to a Sassy CSS (SCSS) file that will compile to css
• codeThemePath: path to a pandoc syntax highlighting file (note that it must be JSON with a .theme extension)
• optionsDocArgs: additional arguments to pass to the nixosOptionsDoc package
