NUR-Kapack repository

NUR-Kapack contains Nix package definitions of the software we work on in the DataMove team: OAR, the Batsim ecosystem, Melissa... This is part of Nix User Repository.

You can see the available packages and their version here

Packages of released versions defined in this repository are built regularly on CI and stored on a Cachix binary cache. You can use it to just fetch prebuilt binaries instead of rebuilding them with the following command.

# Install cachix
nix-env -iA cachix -f https://cachix.org/api/v1/install

# Enable our binary cache for your builds
cachix use capack

Interactive usage

You can enter shells that contain some of our packages with nix run.

# Essential Batsim tools in a single shell (latest release of each tool)
nix run -f https://github.com/oar-team/nur-kapack/archive/master.tar.gz batsim batsched pybatsim batexpe

# The same, but with latest commit on master branch of each tool
nix run -f https://github.com/oar-team/nur-kapack/archive/master.tar.gz batsim-master batsched-master pybatsim-master batexpe-master

You can also install packages in your Nix profile with nix-env.

# Install Batsim latest release in your profile
nix-env -f https://github.com/oar-team/nur-kapack/archive/master.tar.gz -iA batsim

Usage from Nix expressions

You can write Nix expression to define environments that use our packages. Assuming that you have a file named shell.nix that has the following content, you can enter the defined shell by calling nix-shell.

{ kapack ? import
    (fetchTarball "https://github.com/oar-team/nur-kapack/archive/master.tar.gz")
  {}
}:

kapack.pkgs.mkShell rec {
  name = "tuto-env";
  buildInputs = [
    kapack.batsim
    kapack.batsched
    kapack.pybatsim
    kapack.batexpe
  ];
}

If you want to pin the NUR-Kapack version you use, you can do one of the following.

• Use a pinned tarball from GitHub such as https://github.com/oar-team/nur-kapack/archive/2518733fefc28290ecffe44c3234eb2a36b731cd.tar.gz
• Use Nix Flakes

Usage à la NUR

As NUR-Kapack is a NUR, you can use our packages as it is done with other NURs. Please refer to the official NUR documentation for this usage.
