Installation

For closure size reasons DeltaNAR is distributed as 2 separate Nix packages:

• The packing program

This has a relatively larger set of dependencies & is not optimised for closure size.

• The unpacking program

Optimised for closure size & has as small of a dependency set as possible.

Flakes

  description = "DeltaNAR usage";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    deltanar.url = "github:nixos/adisbladis/deltanar";
    deltanar.inputs.nixpkgs.follows = "nixpkgs";
  };

        pkgs = nixpkgs.legacyPackages.${system};
      in {
        default = pkgs.mkShell {
          packages = [
            deltanar.packages.${system}.pack
            deltanar.packages.${system}.unpack

Classic Nix

You can just as easily use deltanar without using Flakes:

let
  pkgs = import <nixpkgs> { };
  inherit (pkgs) lib;

  deltanar = pkgs.callPackage (builtins.fetchGit {
    url = "https://github.com/adisbladis/deltanar.git";
  }) { };
in
  deltanar.pack
