Usage with Xonsh Shell

Hello!

Would it be possible to implement a mach-nix.mkXonsh option, which will install optional modules for the xonsh python-based shell? Or instead, could anyone show me how to implement it myself?

Thank you kindly for your consideration!

extra_pkgs is not available for buildPythonPackage/Applicaiton, only for mkPython. So I changed the expression to first build the xonsh package, and then combine it with the extra package using mkPython:

let
  mach-nix = import (builtins.fetchGit {
   url = "https://github.com/DavHau/mach-nix/";
   ref = "refs/tags/2.3.0";
  });
  pkgs = mach-nix.nixpkgs;

  # build the xonsh package similar like in nixpkgs
  xonsh_pkg = with pkgs.xonsh; mach-nix.buildPythonPackage {
    inherit src LC_ALL postPatch passthru;
    add_requirements = ''
      ply
      prompt_toolkit
      pygments

      # add requirements here
      yubico-client
      pipx
      borgmatic

      # add xontribs here
      xontrib-autojump
      xonsh-direnv
      xontrib-powerline2
    '';
  };

  # build environment with xonsh + python packages from arbitrary sources
  xonsh_env = mach-nix.mkPython {
    extra_pkgs = [
      xonsh_pkg
      "https://gitlab.com/picotech/nanotech/nanite/-/archive/master/nanite-master.tar.gz"
    ];
  };

  # wrap it again to set the passthru variable correctly
  xonsh_shell = with pkgs.xonsh; pkgs.buildEnv {
    inherit name passthru;
    paths = [ xonsh_env ];
  };
in
xonsh_shell

BTW, for specifying extras for normal requirements just use the same notation like in pip. For example requests[socks] to get requests with extras socks.

Oh yeah. I should update the readme. Thanks

In addition, I’m assuming to just import this file as the package value for config.programs.xonsh.package like before?

Excatly. I didn’t try this myself but I assume this must work.
