hdn does not handle builtins.attrValues home.packages expressions

[Bujiraso]

Bug

If I have the following valid Nix config:

  home.packages =   builtins.attrValues {
      inherit (pkgs)
         gnome-2048
         ;
      };

hdn can't figure out how to read the package list.

$ hdn remove gnome-2048
error: could not update home.packages attribute in home.nix
caused by: could not read values of home.packages attribute in home.nix
caused by: Error with array

Suggested Fixes

Either or both of:

1. Ensure these sorts of expressions can be read
2. Handle a # hdn anchor override that I can put into my file to denote where hdn can pretend a [ list ] begins, ignoring surrounding syntax

Context

The impl might be a bit involved on this one, but I'm doing it for a reason (it's not academic).
I do the following, basically:

  home.packages = [
        pkgs.python310Packages.autopep8
      ] ++ builtins.attrValues {
      inherit (pkgs)
          # many
          # Many
          # MANY
          # pkgs.packages ;-) 
          ;
      };

That allows me to not have to put pkgs on everything, yet still also use the python310Packages.autopep8 which does not work if I just bake it in the list.

error: syntax error, unexpected '.'

       at /home/bujiraso/.config/home-manager/home.nix:181:28:

          181|           python310Packages.autopep8
             |                            ^
(use '--show-trace' to show detailed location information)

Perhaps a bug is required for home-manager, too, on that one, but I haven't gotten around to it.

Please help me understand the purpose of using builtins.attrValues; I'm not sure I understand the context section.

Why not use:

home.packages = with pkgs; [
    python310Packages.autopep8
    # other packages, `pkgs` prefix is not necessary
];

This works on my installation, with editing the file manually and with hdn.

Sure.
