Omit item in list

[Quentin Aveno]

Hi !
Is there any way to omit a item in a list at the declaration ?

- name: "Test"
  hosts: localhost
  vars:
    test1: false
    test2:
      - name: test21
        includes:
          - { file: "file221.j2", path: "/somewhere/" }
          - { file: "file222.j2", path: "/somewhere/" }
          - "{{ ( test1 | ternary ({ 'file': 'file223.j2', 'path': '/somewhere/' }, omit) ) }}"
  tasks:
    - debug:
        var: test2
    - debug:
        msg: "{{ item.1.path + item.1.file }}"
      with_subelements:
        - "{{ test2 }}"
        - "includes"

I would like, if it's possible, to not change the task itself, only the variables.

Thank you,
Have a nice day even in these difficult times

It's look like I misunderstood omit behavior and there is no way to do what I'm trying to do : https://github.com/ansible/ansible/issues/22417

Adding the item conditionally seems to be easier, I think

vars:
test1: false
list1:

- {file: "file221.j2", path: "/somewhere/"}
- {file: "file222.j2", path: "/somewhere/"}

list2: |
{% if test1 %}
[{{ list1 }} + [{'file': 'file223.j2', 'path': '/somewhere/'}]]
{% else %}
{{ list1 }}
{% endif %}
test2:
- name: test21
includes: "{{ list2 }}"

HTH,

Thanks Vlad for your proposition.
Excuse me for don't be enough precise in my first comment, but it's a more complex dict (than the example) and I can't split in two lists, it have to be one list and some items which could be undefined/omit.
I'm not the only one to use those variables and the includes have to be in the same list (the one mandatory as the the optional).
