# OCaml-focused custom [Nix Overlays](https://nixos.wiki/wiki/Overlays)

This repo contains a set of custom overlays and upgrades over the upstream

nixpkgs set of (mostly) OCaml packages, and a few other curated derivations.

## Using this set of packages

### With Flakes

In your `flake.nix`:

```nix

{

  # Use this repo as the `nixpkgs` URL

  inputs.nixpkgs.url = "github:nix-ocaml/nix-overlays";

  outputs = { self, nixpkgs }:

    let

      pkgs = nixpkg.legacyPackages.${"YOUR_SYSTEM_STRING"};

    in

    {

      ...

    };

}

```

#### Alternative (advanced)

```nix

{

  inputs.nixpkgs.url = "github:nixOS/nixpkgs";

  inputs.ocaml-overlay.url = "github:nix-ocaml/nix-overlays";

  inputs.ocaml-overlay.inputs.nixpkgs.follows = "nixpkgs";

  outputs = { self, nixpkgs, ocaml-overlay }:

    let

      system = "YOUR_SYSTEM_STRING";

      pkgs = import nixpkgs {

        inherit system;

        overlays = [

          ocaml-overlay.overlays.default

        ];

      };

    in

    {

      ...

    };

}

```

### Without Flakes

```nix

let

  nixpkgs-sources =

    builtins.fetchTarball

      https://github.com/nix-ocaml/nix-overlays/archive/master.tar.gz;

  pkgs = import nixpkgs-sources { };

in

pkgs

```

#### Alternative (advanced)

```nix

let

  nixpkgs-sources =

    builtins.fetchTarball

      https://github.com/nix-ocaml/nix-overlays/archive/master.tar.gz;

  custom-nixpkgs = /path/to/custom/nixpkgs;

  pkgs = import custom-nixpkgs {

    overlays = [

      (import "${nixpkgs-sources}/overlay" custom-nixpkgs)

    ];

  };

in

pkgs

```
