getting Hound-CI to show Rubocop “cop names” again

Thoughtbot’s Hound-CI service runs Rubocop on Ruby projects. It had a setting to show the name of the “cop” (style rule) that failed, which made it easier to look up the options for that specific rule.

At some point, the way that was configured changed. Now instead of putting ShowCopNames: true in the rubocop.yml file, it’s gotta be something like this:

AllCops:
  DisplayCopNames: true
