OCaml-focused custom Nix 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:

{
  # 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)

{
  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
    {
      ...
    };
}
