nix-option-types

To define robust Nix module options, use helper functions like mkEnableOption, mkPackageOption, and mkOption. These helpers standardize option declarations, reducing errors and simplifying your Nix configuration interfaces.

When building a Nix module interface, you can use basic and collection types including strings, ints, ports, paths, and packages. These types ensure consistent option typing and validate inputs for scalable definitions.

Use mkEnableOption in nixpkgs for simple boolean flags that enable features, defaulting to false. Use mkOption when you need custom defaults, complex types, or detailed descriptions for broader configuration control.

To structure scalable Nix module option definitions across multiple files, apply consistent submodule patterns and helper-based declarations. This approach standardizes interfaces, ensuring your module library remains maintainable as it grows.
