I already know that if you have long conditionals with and between them you can use lists to split them on multiple lines.
Still, I am not aware of any solution for the case where you have OR between them.
Practical example from real life:
when: ansible_user_dir is not defined or ansible_python is not defined or ansible_processor_vcpus is not defined
This line is ugly and hard to read, and clearly would not fit a 79 column.
How can we rewrite it to make it easier to read?

Split Lines in Ansible You can use the 'split()' function to divide a line into smaller parts. The output will be a list or dictionary. This is a Python function and not a Jinja2 filter. For example, in the below example, I am splitting the variable 'split_value' whenever a space character is seen.
By default Ansible sends output about plays, tasks, and module arguments to your screen (STDOUT) on the control node. If you want to capture Ansible output in a log, you have three options: To save Ansible output in a single log on the control node, set the log_path configuration file setting.
Use the YAML folding operator >
when: >
ansible_user_dir is not defined or
ansible_python is not defined or
ansible_processor_vcpus is not defined
As the ansible documentation states:
Values can span multiple lines using
|or>. Spanning multiple lines using a Literal Block Scalar|will include the newlines and any trailing spaces. Using a Folded Block Scalar>will fold newlines to spaces; it’s used to make what would otherwise be a very long line easier to read and edit. In either case the indentation will be ignored.
