Ansible: Shows multi-line commands executed in the shell module with line breaks

Request

I want to check the multi-line command executed in the shell module in the subsequent debug module with line breaks.

solution

I couldn't find a suitable one in the filter, but it is possible with splitlines () in python

playbook example

playbook.yml

---
- hosts: all
  gather_facts: false
  tasks:

    - shell: |
        echo a
          echo b
        echo c
      register: r

    - debug: { var: r.cmd }              # <=Hard to read if output as it is
    
    - debug: { var: r.cmd.splitlines() } # <= splitlines()Separated at

    - debug: { var: r.stdout_lines }
    - debug: { var: r.stderr_lines }

Execution example

$ ansible-playbook -i localhost, -c local playbook.yml

PLAY [all] *******************************************************************************************************

TASK [shell] *****************************************************************************************************
changed: [localhost]

TASK [debug] *****************************************************************************************************
ok: [localhost] => {
    "r.cmd": "echo a\n  echo b\necho c\n" # <=Example of output as it is
}

TASK [debug] *****************************************************************************************************
ok: [localhost] => {
    "r.cmd.splitlines()": [
        "echo a",　　　　　　　　　　　　　　　# <=Example of output separated by lines
        "  echo b",　　　　　　　　　　　　　　# <=Example of output separated by lines
        "echo c"　　　　　　　　　　　　　　　　# <=Example of output separated by lines
    ]
}

TASK [debug] *****************************************************************************************************
ok: [localhost] => {
    "r.stdout_lines": [
        "a",
        "b",
        "c"
    ]
}

TASK [debug] *****************************************************************************************************
ok: [localhost] => {
    "r.stderr_lines": []
}

PLAY RECAP *******************************************************************************************************
localhost                  : ok=5    changed=1    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   

Note that the command module (not the shell module) cannot be used because it is not passed as a string to the registry variable. It would be nice if it could be displayed separately by line even when it fails.
