    Sagemath flake

    You'll want to run the flake with the following command:

    $ sage --nodotsage -n=jupyterlab --notebook-dir /path/to/notebooks

    For example:

    $ sage --nodotsage -n=jupyterlab --notebook-dir .
  '';

  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
  inputs.flake-utils.url = "github:numtide/flake-utils";

  outputs = { self, nixpkgs, flake-utils}:
    flake-utils.lib.eachDefaultSystem
    (system:
      let
        pkgs = import nixpkgs {
          inherit system;
        };
      in {
        devShells.default = pkgs.mkShell {
          buildInputs = with pkgs; [
            sageWithDoc
          ];
        };
      }
    );
}
