I’m trying to write my first Ansible module. How do I refer to the built-in facts that Ansible gathers during the setup phase? I just want to be able to do this inside my module, for example.I want to be able to do the “when” part in my module.

`

- name: Issue some command  
command: ls -al /tmp  
when: (ansible\_product\_version | search(“.\*.amazon”))

`
