zypper: Add parameter to list all updatable packages

[seraphyn]

Summary

I try to list all available updates like in dnf, apt, or yum, but this feature isn't implemented atm.
I helped myself to write this Playbook years ago, but in my opinion this should be an parameter in the module zypper

- hosts: sles
  become: true
  become_user: root
  tasks:
          - name: Zypper Update awk to file
            shell:
                " zypper ref && zypper lu | awk '{print $5, $7, $9 }' | sed -e '1,10d' | sed 's/\"//' > /tmp/awklist.txt "
            register: lsout
            tags: lsout

          - name: show awklist
            shell : cat /tmp/awklist.txt
            register: displaylist

          - debug: msg="{{displaylist.stdout_lines}}"
          - 

It's not perfect but fits atm

This should be (part of) a separate module, like zypper_info. (See https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_best_practices.html#scoping-your-module-s on list/info/get states.)

[seraphyn]

You're right.
But there's no zypper_info atm

[felixfontein]

Indeed. So far nobody created one :)
