overlays

The overlay and overlays options allow you to configure overlays outputs.

Multiple provided overlays for an output are merged.

The overlay option adds the overlay to overlays.default.

The overlays option allows you to add overlays to overlays outputs.

Usage

For example, to add an overlay to overlays.default, do the following:

{
  inputs.conflake.url = "github:ratson/conflake";
  outputs = { conflake, ... }:
    conflake ./. {
      overlay = final: prev: { testValue = "hello"; };
    };
}

The above results in overlays.default output containing testValue.

To configure other overlays:

{
  inputs.conflake.url = "github:ratson/conflake";
  outputs = { conflake, ... }:
    conflake ./. {
      overlays.cool = final: prev: { testValue = "cool"; };
    };
}

The above results in a overlays.cool output.
