Looks like a very nice way to handle these kind of loops!

[nodeselector]

Not sure that these changes would fix #46203 I tested @bcoca's branch locally with this playbook:

- hosts: localhost
  gather_facts: false
  tasks:
  - name: testing block looping
    block:
      - debug:
          msg: "{{ item }}"
    loop:
      - 1
      - 2
      - 3
    loop_control:
      until: item > 2

Which yields:

ansible-playbook test/integration/targets/loop_control/block_play.yml
[WARNING]: You are running the development version of Ansible. You should only run Ansible from "devel" if you are modifying the

point.
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'
ERROR! 'loop' is not a valid attribute for a Block

The error appears to be in '/Users/jeffmartin/dev/ansible/test/integration/targets/loop_control/block_play.yml': line 4, column 5, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  tasks:
  - name: testing block looping
    ^ here

Am I missing something?

[nodeselector]

Ah I see what I was missing, this fix would only apply to includes not block. This works great:

- hosts: localhost
  gather_facts: false
  tasks:
  - name: testing inlcude looping
    include_tasks: some_tasks.yml
    loop:
      - 1
      - 2
      - 3
    loop_control:
      until: item > 2

Can you guys please fix this, the people are really hoping for this feature.

[pini-gh]

I've had some success using when as described here. This is not exactly an until or break feature, but it can be used for the same purpose.

[Mohammad-Atif-Khan]

@bcoca is this still intended to be made a core feature? would be very useful to have, it makes a lot of sense to be able to break out of a loop based on any condition.

[bcoca]

probably, but not a priority right now
