was able to get it compiling with this:

pkgs.rustPlatform.buildRustPackage rec {
  pname = "bend";
  version = "0.2.7";

  src = pkgs.fetchFromGitHub {
    owner = "higherorderco";
    repo = pname;
    rev = version;
    hash = "sha256-yQI+p3PT1Czruc8+OZ/lZLAkBjkchkRw/OoGCYxHTDY=";
  };

  # NOTE: broken tests - something with hvm calls
  doCheck = false;

  cargoHash = "sha256-YPPBtgxqfoKnGb77m/CUYQ7+vVgL5MHhJ8I3TQ1rqK8=";

  buildInputs = [ pkgs.hvm ];

  RUSTC_BOOTSTRAP = true;

  meta = {
    description = "A massively parallel, high-level programming language";
    homepage = "https://github.com/HigherOrderCO/bend";
    license = pkgs.lib.licenses.asl20;
  };
};

but when i run it like bend run tmp.bend (tmp.bend exists) i get this:

Errors:
While running hvm: No such file or directory (os error 2)

thought the hvm build input would fix that but no

hopefully im just being stupid somehow

Add a 👍 reaction to issues you find important.

You're alllmost there. For runtime deps, you should use wrapProgram. Replace the buildInputs line with:

  nativeBuildInputs = [ pkgs.makeWrapper ];
  postInstall = ''
    wrapProgram $out/bin/bend \
      --prefix PATH : ${pkgs.lib.makeBinPath [ pkgs.hvm ]}
  '';

ty :) ok this compiles but i have a different error now:

Errors:
Error reading result from hvm. Output :
Expected `Term`:
  2 | HVM_MAIN_CALL = .out.hvm
exit status: 1

using the all_tree.bend example running bend run all_tree.bend.

i was thinking i might have to wait till it gets a bit more stable but ive seen fireship do it so i tried making a nix package as soon as possible :).

That error is caused by hvm being out of date. The version of hvm in nixpkgs is 1.0.9, but bend needs version 2.

I've created a PR to bump hvm to version 2: #313053
