Building a project without a lockfile.jdn about janet-nix HOT 5 CLOSED

Even with the fork I can't get it to work, since Judge uses declare-binscript.

Hey @giodamelio apologies for the late response, only just saw this. I actually ran into this same issue when trying to build with Judge recently, I'll take a look see what options are available

No worries at all. I am pretty new to Nix and brand new to Janet, so thanks for providing this project to hack on.

Thanks for the quick update! I will give it a shot this weekend.

from janet-nix.

I've added a new attribute extraDeps to pass dependencies directly to mkJanet, so it's possible to generate the sources in advance:

~/repos/judge $ jpm make-lockfile && nix run github:turnerdev/janet-nix
...
[
  { url = "https://github.com/ianthehenry/cmd"; rev = "7551225818a8a5f6665a918f1862db0c7704a1f4"; submodules = true; }
]

Unfortunately I still run into issues trying to build a working derivation for Judge. I got close with this:

{
  judge = janet-nix.packages.${system}.mkJanet {
    name = "judge";
    src = builtins.fetchGit {
      url = "https://github.com/ianthehenry/judge";
      rev = "c2a7eadf6cbf9ffad6f880c2ddbdbc03009a655f";
    };
    extraDeps = [{
      url = "https://github.com/ianthehenry/cmd";
      rev = "7551225818a8a5f6665a918f1862db0c7704a1f4";
    }];
    main = ''
      (import cmd)
      (import judge/runner)
      (defn main [& args]
        (put root-env :syspath (string (os/getenv "JANET_TREE") "/lib"))
        (setdyn *executable* "")
        (setdyn *args* (drop 1 (dyn *args*)))
        (cmd/main runner/main)
        (main))
    '';
  };
}

But it seems declare-binscript output expects to be interpreted as a script rather than run as a standalone binary. Passing a modified version of src/judge to the new main attribute gets it to build and run, but it still has issues.

After giving it more thought, it probably makes sense to just install Judge into the local environment via jpm install, since the tests (use judge) anyway. For an example see https://github.com/turnerdev/janet-nix/blob/main/templates/full/flake.nix#L71-L76

Thanks again for the feedback!
