Hi,

I’m just wondering if there is any settings that can make Ansible throw a warning or error out if a variable is not defined anywhere?

Any thoughts would be much appreciated.

Yes, there’s already a parameter for this added in Ansible 1.3.

look in examples/ansible.cfg from a current checkout.
