cannot pass ARGS to NIX_BINARY if args starts with dash

**Describe the bug** `nixglhost -h` the CLI help says ``` positional arguments: NIX_BINARY Nix-built binary you'd like to wrap. ARGS The args passed to the wrapped binary. ``` I take it that `ARGS` is passed to `NIX_BINARY`, but this is not the case: ``` [nix-shell:~/work/nix-expression-test]$ date Mon Aug 12 10:24:48 CST 2024 [nix-shell:~/work/nix-expression-test]$ date -u Mon Aug 12 02:24:52 UTC 2024 [nix-shell:~/work/nix-expression-test]$ nixglhost date Mon Aug 12 10:24:56 CST 2024 [nix-shell:~/work/nix-expression-test]$ nixglhost date -u usage: nixglhost [-h] [-d DRIVER_DIRECTORY] [-p | --print-ld-library-path | --no-print-ld-library-path] [NIX_BINARY] [ARGS ...] nixglhost: error: unrecognized arguments: -u [nix-shell:~/work/nix-expression-test]$ nixglhost echo hello world hello world ``` **To Reproduce** use [this](https://gist.github.com/tutankalex/97586db50be05d8121177ce3db923b25/36cff7dc0cabbceafc20efda511088a368ff810a) shell.nix file (also pasted verbatim below) <details> ```nix { pkgs ? import <nixpkgs> { config = { allowUnfree = true; cudaSupport = true; }; } }: let nixglhost-sources = pkgs.fetchFromGitHub { owner = "numtide"; repo = "nix-gl-host"; rev = "main"; # Replace this with the hash Nix will complain about, TOFU style. hash = "sha256-IDDkwDetQ/a5U2WzlGbLD6i/K++9moKQdpIJP3QEg4I="; }; nixglhost = pkgs.callPackage "${nixglhost-sources}/default.nix" { }; in pkgs.mkShell { nativeBuildInputs = with pkgs.buildPackages; [ nixglhost python3 # pin: python311 cudaPackages.cudatoolkit # pin: cudaPackages_12.cudatoolkit python3Packages.pytorch-bin # pin: python311Packages.pytorch-bin python3Packages.pip # pin: python311Packages.pip ]; shellHook = '' export CUDA_PATH=${pkgs.cudatoolkit} # nixglhost discourages `nixglhost -p`, though as of this writing, # its support for passing arguments in CLI is not working as expected export LD_LIBRARY_PATH=$(nixglhost -p):${pkgs.stdenv.cc.cc.lib}/lib''${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH} alias run-sanity-test='python -c "import torch; print(torch.cuda.is_available())"' ''; } ``` </details> **Expected behavior** dash arguments should get passed as-is **System information** ``` $ nix-shell -p nix-info --run 'nix-info -m' - system: `"x86_64-linux"` - host os: `Linux 6.5.0-44-generic, Ubuntu, 22.04.3 LTS (Jammy Jellyfish), nobuild` - multi-user?: `yes` - sandbox: `yes` - version: `nix-env (Nix) 2.17.0` - channels(root): `"nixpkgs"` - nixpkgs: `/home/tutankalex/.nix-defexpr/channels/nixpkgs` ``` **Additional context** ok, checked the nixglhost source before submitting, and realize this is due to ```python parser.add_argument( "ARGS", type=str, nargs="*", help="The args passed to the wrapped binary.", default=None, ) ``` as a result, it **is** possible to send in arguments via ```sh $ nixglhost -- date -u Mon Aug 12 02:36:10 UTC 2024 ``` but apparently if you change that block to ```python parser.add_argument( "ARGS", nargs=argparse.REMAINDER, help="The args passed to the wrapped binary.", default=None, ) ``` it appears to work "as expected" ```sh $ nixglhost date -u Mon Aug 12 02:36:43 UTC 2024 ``` this syntax is breaking behavior, but is consistent with the help message as well as `nixGL`.
