Variables starting with underscore violate Ansible documentation rule
jlmuir opened this issue · 4 comments
In vars/{Debian,RedHat}.yml, two variables are defined that start with an underscore character: __ruby_packages and __ruby_build_packages, but in the Ansible User Guide at Working With Playbooks > Using Variables > Creating valid variable names, it says:
Variable names should be letters, numbers, and underscores. Variables should always start with a letter.
Hmm, now I see that you do this in a number of your published roles and recommend it in your "Ansible for DevOps" book in Appendix B - Ansible Best Practices and Conventions > Playbook Organization > Use role defaults and vars correctly.
Frankly, this scheme seems quite reasonable to me, and I'd like to use it in roles I create, but I'm struggling with how to reconcile it with the variable naming rule I pointed out in the Ansible User Guide.
