What to contribute

This repository, rubocop-github, is part of a broader RuboCop ecosystem.

If the Cop you would like to propose is generally applicable outside of GitHub:

1. Propose the change upstream in the core open source project (e.g. rubocop, or rubocop-rails), where it will have maximal visibility and discussion/feedback.
2. Patch the change provisionally into GitHub's project(s), for immediate benefit; that can include this repository.
3. ...if the proposal is accepted, remove the patch and pull the updated upstream.
4. ...if the proposal is not accepted, we usually learn something about our proposal, and we then choose whether to maintain the patch ourselves, discard it, or identify a better open-source home for it.

If the Cop is only applicable for GitHub, then this is the right place to propose it.

For Maintainers

Updating Rubocop Dependencies

Rubocop regularly releases new versions with new cops. We want to keep up to date with the latest Rubocop releases, and keep these rules and styleguide in sync to reduce burden on consumers of this gem.

• Run bundle update rubocop rubocop-performance rubocop-rails to update the dependencies within this repository. Major updates will require updating the .gemspec file because of the pinned version constraints.

• Run bundle exec rubocop, and copy the output of newly introduced rules into config/default_pending.yml and config/rails_pending.yml. They should look like this:

  Lint/DuplicateMagicComment: # new in 1.37
    Enabled: true
  Style/OperatorMethodCall: # new in 1.37
    Enabled: true
  Style/RedundantStringEscape: # new in 1.37
    Enabled: true
  

• Run bundle exec rubocop again to ensure that it runs cleanly without any pending cops. Also run bundle exec rake to run the tests.

• Work through the pending cops, and copy them to config/{default,rails}.yml with an explicity Enabled: true or Enabled: false depending on your decision as to whether they should be part of our standard ruleset.
