Setting name to an empty list

[pmav99]

Hi

When you specify an empty list to name, then a error is raised. E.g.:

---

- name: "install aur packages"
  hosts: "localhost"
  connection: "local"
  become: True

  vars:
    # aur_pkgs: []    # This fails with an explicit fail message
    aur_pkgs:      # This raises an exception

roles:
    - name: "Install AUR packages"
      kewlfft.aur.aur:
        name: "{{ aur_pkgs }}"
        use: "yay"
        state: "present"
      become_user: "aur_builder"

Obviously, not a huge issue, but this behavior is different from what e.g. ansible.builtin.package does. so i was a bit surprised by it.

FWIW, my use case is having a playbook template which contains something like this:

  vars:
    remove_pkgs:
    pkgs:
    aur_pkgs:

  tasks:
    - name: "Uninstall packages"
      ansible.builtin.package:
        name: "{{ remove_pkgs }}"
        state: "absent"

    - name: "Install packages"
      ansible.builtin.package:
        name: "{{ pkgs }}"
        state: "present"

    - name: "Install AUR packages"
      kewlfft.aur.aur:
        name: "{{ aur_pkgs }}"
        use: "yay"
        state: "present"
      become_user: "aur_builder"

and where I fill in the variables with values as necessary. As it is, I need to comment out the AUR stuff. Again, not a huge deal, but I don't really see why the playbook should fail.

I could make a PR if you agree with this behavior change

I haven't looked into it into details but in general I agree to follow the behavior of ansible.builtin.package
OK with the PR and if you can clarify how it will react after vs before the PR
