Hi Guys

I was going over the noop.py plugin callbacks on github (see [https://github.com/ansible/ansible/blob/devel/lib/ansible/callback\_plugins/noop.py](https://github.com/ansible/ansible/blob/devel/lib/ansible/callback_plugins/noop.py)) and noticed there is no callback for a task’s changed status. Any reason for this ?

Regards

There’s always a reason 🙂

In this case, it’s unnecessary.

changed True/False is mixed in with the attributes of the return datastructure.

Thanks for the reply.

Okay; well, I am trying to build a plugin that will print the task’s stdout rather than just return “changed/ok”. I could register a variable and then debug: var=var but that becomes somewhat wearisome when tasks are abundant. The plan was to latch onto runner\_on\_changed or something but thats obviously not going to work with this revelation.

Do you know what I need to do in order to achieve this goal ?

Regards

All commands that return stdout do in fact show this when using “-v”.

I don’t think you’d need to write one.

We might be interested in a language feature for a “verbose: True” property on a task that forces verbosity if not already set.

I am aware of the -v argument but it is not very user friendly hence why I want to create the plugin which will format the output. A verbose module would be nice provided it allow for some form of formatting.

Yeah, patches for that would be welcome. I’m not sure how hard it would be, but I suspect not terrible.
