with_nested loop with more than 3 elements

[Vincent Hardion]

Hi,

I just want to confirm the behavior of "with_nested" before to submit a pull request.

If I add another element to the loop_nested example like this:

---

# this is a trivial example of how to do a nested loop.

- hosts: all

  tasks:

    - shell: echo "nested test a={{ item[0] }} b={{ item[1] }} c={{ item[2] }} d={{ item[3] }}"

      with_nested:

        - [ 'red', 'blue' ]

        - [ 1, 2 ]

        - [ 'up', 'down']

        - [ 'top', 'bottom']

Should the ouput be :

$ ansible-playbook -i hosts loop.yml 

...

TASK: [shell echo "nested test a={{item[0]}} b={{item[1]}} c={{item[2]}} d={{item[3]}}"] *** 

changed: [localhost] => (item=[['red', 1], 'up', 'top'])

changed: [localhost] => (item=[['red', 1], 'up', 'bottom'])

changed: [localhost] => (item=[['red', 1], 'down', 'top'])

changed: [localhost] => (item=[['red', 1], 'down', 'bottom'])

changed: [localhost] => (item=[['red', 2], 'up', 'top'])

changed: [localhost] => (item=[['red', 2], 'up', 'bottom'])

changed: [localhost] => (item=[['red', 2], 'down', 'top'])

changed: [localhost] => (item=[['red', 2], 'down', 'bottom'])

changed: [localhost] => (item=[['blue', 1], 'up', 'top'])

changed: [localhost] => (item=[['blue', 1], 'up', 'bottom'])

changed: [localhost] => (item=[['blue', 1], 'down', 'top'])

changed: [localhost] => (item=[['blue', 1], 'down', 'bottom'])

changed: [localhost] => (item=[['blue', 2], 'up', 'top'])

changed: [localhost] => (item=[['blue', 2], 'up', 'bottom'])

changed: [localhost] => (item=[['blue', 2], 'down', 'top'])

changed: [localhost] => (item=[['blue', 2], 'down', 'bottom'])

or

TASK: [shell echo "nested test a={{item[0]}} b={{item[1]}} c={{item[2]}} d={{item[3]}}"] *** 

changed: [localhost] => (item=['red', 1, 'up', 'top'])

changed: [localhost] => (item=['red', 1, 'up', 'bottom'])

changed: [localhost] => (item=['red', 1, 'down', 'top'])

changed: [localhost] => (item=['red', 1, 'down', 'bottom'])

changed: [localhost] => (item=['red', 2, 'up', 'top'])

changed: [localhost] => (item=['red', 2, 'up', 'bottom'])

changed: [localhost] => (item=['red', 2, 'down', 'top'])

changed: [localhost] => (item=['red', 2, 'down', 'bottom'])

changed: [localhost] => (item=['blue', 1, 'up', 'top'])

changed: [localhost] => (item=['blue', 1, 'up', 'bottom'])

changed: [localhost] => (item=['blue', 1, 'down', 'top'])

changed: [localhost] => (item=['blue', 1, 'down', 'bottom'])

changed: [localhost] => (item=['blue', 2, 'up', 'top'])

changed: [localhost] => (item=['blue', 2, 'up', 'bottom'])

changed: [localhost] => (item=['blue', 2, 'down', 'top'])

changed: [localhost] => (item=['blue', 2, 'down', 'bottom'])

Note in the second case, each element is a flatten list.

Thanks in advance.

Best regards,

Vincent

It should be the second.
