I have a Ansible play for PGBouncer that displays some output from a stats module built into PGBouncer.

My issue is that when Ansible prints the output to the terminal it mangles the newlines. Instead of seeing

----------

| OUTPUT |

----------

I see

----------n| OUTPUT |n----------

Does anyone know how to get Ansible to "pretty print" the output?

There isn't a way to do what you want natively in Ansible.
You can do this as a workaround:

ansible-playbook ... | sed 's/\n/n/g'

If you want more human friendly output define:

ANSIBLE_STDOUT_CALLBACK=debug

This will make ansible use the debug output module (previously named human_log) whinch despite its unfortunate name is less verbose and much easier to read by humans.

If you get an error that this module is not available, upgrade Ansible or add this module locally if you cannot upgrade ansible, it will work with over versions of ansible like 2.0 or probaly even 1.9.

Another option to configure this is to add stdout_callback = debug to your ansible.cfg

You can use the pause module:

- pause:

    prompt: "{{ variable_blob.stdout }}"

Moves on without input by defining minutes or seconds but then user input is not captured.
