As I lamented in my article on converting to the PDK, I really do not like Rubocop and was disappointed I could not turn it off. Thankfully, that was addressed in PDK-998 and the fix was included in time for PDK 1.6.0! Disabling it is pretty simple and though it’s strictly a fix to pdk-templates, updating the PDK won’t hurt.

First, update to PDK 1.6.0. As I use CentOS 7 and the RPM packaging, it’s as simple as sudo yum update pdk -y; follow the directions that match system. Next, we need to add the following lines to .sync.yml:

.rubocop.yml:
  selected_profile: off

Finally, run pdk update, or if you weren’t already using pdk-templates, run pdk convert --template-url=https://github.com/puppetlabs/pdk-templates (I will assume the former to keep it simple). You can add --noop (or say n) and review update.txt|convert.txt to see the differences before applying, or, because you are using version control, just run a diff afterward to see the changes.

That’s it! Check the contents of .rubocop.yml and you will notice everything is false (just a snippet because it’s loooong):

Running validation now finds no issues with ruby syntax no matter how much you ignore style guides:

You may have noticed there are quite a few other files updated. The other significant change is that a :changelog task via github_changelog_generator is now included, so you can remove that from your .sync.yml if you added it and replace it with the recommended config (via the Rakefile):

---
Gemfile:
  optional:
    ':development':
      - gem: 'github_changelog_generator'
        git: 'https://github.com/skywinder/github-changelog-generator'
        ref: '20ee04ba1234e9e83eb2ffb5056e23d641c7a018'
        condition: "Gem::Version.new(RUBY_VERSION.dup) >= Gem::Version.new('2.2.2')"

The other changes are pretty minor, in some cases cosmetic, but of course review them to make sure they’re OK. Submit a PR or equivalent and make sure the tests pass before merging. You can follow along with today’s blog post in domain_join PR35, too.

Enjoy!
