debug module: possible pull request

[Erik Anderson]

As currently implemented, if, in a moment of confusion, you pass in a variable directly instead of var=foo or msg=foo, the debug module's output is less than helpful.

For instance, if I run this against a host:

---

- hosts: all

  tasks:

  - debug: foo

...the debug module returns:

ok: [default] => {

    "msg": "Hello world!"

}

Is that the intended behavior? It seems as if it would be more helpful to, instead of printing "Hello world!", to raise an exception with a message that the user needs to specify var= or msg=.

If this change would be desirable, I'll submit a pull request for it.

It's the way it's not very good.

Basically "Hello World" is the default "msg".

I would almost think that if there was no "=" in the line and the value was not a hash you could assume it was doing msg="<string value>" maybe?
