rubocop-greenroom

rubocop-greenroom reports structural problems that RuboCop can identify from one Ruby file.

Add the plugin to the host application's .rubocop.yml:

plugins:
  - rubocop-greenroom

The plugin enables three cops:

• Greenroom/ScienceBlockShape requires one use, one try, and one compare call in that order.
• Greenroom/UnsafeScienceBody reports unsafe return and binding expressions in use and try bodies.
• Greenroom/CandidateIsPrivate reports a visible same-class candidate definition that is public or protected.

These cops inspect one file. A separate diff checker verifies that a use body preserves the previous method body.
