Subclassing ansible.utils.display.Display in custom callback plugin

Hi all,

please allow me to ask for any help here…
I once wrote a custom callback plugin, where I subclassed ansible.utils.display.Display so I could overrule it’s display() method to manipulate the message to be printed, and then call super(Display, self).display(…
Since Ansible 2.8 the Display object is now a singleton, instantiated right at ‘ansible-playbook’. This means a cannot modify the Display.display() anymore right ?

Any ideas on how to call a customized display() method ?

Thanks in advance for any help.

Pieter.

To answer myself… I figured this simple solution :

in ‘init()’
…
self.realdisplay = self._display.display
self._display.display = self.display

then add a ‘display()’ method that intercept my message, and then calls ‘self.realdisplay()’

Gonna run some tests now. Thanks for your time so far…

Pieter
