[matthew-piziak]

Project description
Pueue is a command line queue management tool for sequential and parallel execution of long running tasks.

Installation Vector

This package is conventionally installed through pip install pueue or python setup.py install, so it should be packaged like other Python programs.

Hey. Maintainer from pueue here.
Pueue has been rewritten in Rust. It can now easily be deployed via binary or clean installed via cargo.

[matthew-piziak]

Hi @Nukesor, great to hear from you! And it's nice to hear that Pueue has been rewritten in Rust. It would be easier to package if it had an upstream Cargo.lock file. Would you be willing to provide one?

[Nukesor]

Hey @matthew-piziak
Sorry for the delay, I wanted to release a new version that fixes some things before pinging you.

Cargo.lock is added.

[matthew-piziak]

Wow, thanks @Nukesor, much appreciated.

Here's the expression I'm using:

pueue = pkgs.rustPlatform.buildRustPackage rec {
  pname = "pueue";
  version = "0.1.2";
  src = pkgs.fetchFromGitHub {
    owner = "Nukesor";
    repo = "pueue";
    rev = "b0f7015b155a03d961c30e484476f3fc23f256db";
    sha256 = "0hp5ri8mcvbmnwprsfqwprr31xv0qpd0ack96zs3nj0lf2l14g2p";
  };
  cargoSha256 = "1idjl1qlln5db1fs4dpsisymsxfz2s7qgzc0pkx8i6y415nvvwaw";
  verifyCargoDeps = true;
  meta = with pkgs.stdenv.lib; {
    description =
      "A command-line task management tool for sequential and parallel execution of long-running tasks.";
    homepage = "https://github.com/Nukesor/pueue";
    license = licenses.mit;
    platforms = platforms.unix;
  };
};

When I build it I get a build failure in the bytes dependency of all things:

error: `core::slice::<impl [T]>::len` is not yet stable as a const fn
   --> /build/pueue-0.1.2-vendor/bytes/src/bytes.rs:130:18
    |
130 |             len: bytes.len(),
    |                  ^^^^^^^^^^^

error: aborting due to previous error

error: Could not compile `bytes`.
warning: build failed, waiting for other jobs to finish...
error: build failed

It looks like pueue CI is red for this build too, but for a different reason: build #81

Is this error familiar to you? If not it might be something about how buildRustPackage works in Nix. My main hunch is that I'm implicitly using a rustc that does not meet the Rust>=1.39 constraint of pueue.

[Nukesor]

Travis' pipeline failed on the old python version :D Totally forgot this still existed.
The Github Actions pipeline is working for both rust stable and nightly (just added a badge to the Readme)

I just looked at the Nixpkg rust section and it looks like there is an option to set the Rust version:
https://github.com/NixOS/nixpkgs/blob/master/doc/languages-frameworks/rust.section.md#controlling-rust-version-inside-nix-shell

Also looked at the error you got there. It's indeed another feature that got stablilized in Rust v1.39.

Thanks for packaging this for NixOs. I'm kind of honored :)

Aha, I just used pkgs.unstable.rustPlatform so that I got the unstable channel instead of NixOS 19.09. This works!

pueue = pkgs.unstable.rustPlatform.buildRustPackage rec {
  pname = "pueue";
  version = "0.1.3";
  src = pkgs.fetchFromGitHub {
    owner = "Nukesor";
    repo = "pueue";
    rev = "0e22b660c90a5ab83613af1166c94ce0b457f044";
    sha256 = "1665jcibq5kpz6prmk26zj9w0rb3zw9rlrzml0vmqys121x55phs";
  };
  cargoSha256 = "1gjamwxvr6hfv4iija16k1f9cw6jmry833p4fhq4gshz2kb6bbmh";
  verifyCargoDeps = true;
  meta = with pkgs.stdenv.lib; {
    description =
      "A command-line task management tool for sequential and parallel execution of long-running tasks.";
    homepage = "https://github.com/Nukesor/pueue";

    platforms = platforms.unix;
  };
