RuboCop GitHub

This repository provides recommended RuboCop configuration and additional Cops for use on GitHub open source and internal Ruby projects, and is the home of GitHub's Ruby Style Guide.

Add rubocop-github to your Gemfile, along with its dependencies:

gem "rubocop-github", require: false
gem "rubocop-performance", require: false
gem "rubocop-rails", require: false

Inherit all of the stylistic rules and cops through an inheritance declaration in your .rubocop.yml:

# .rubocop.yml
inherit_gem:
  rubocop-github:
  - config/default.yml # generic Ruby rules and cops
  - config/rails.yml # Rails-specific rules and cops

Alternatively, only require the additional custom cops in your .rubocop.yml without inheriting/enabling the other stylistic rules:

# .rubocop.yml
require:
  - rubocop-github  # generic Ruby cops only
  - rubocop-github-rails # Rails-specific cops only

💭 Looking for config/accessibility.yml and the GitHub/Accessibility configs? They have been moved to a new gem.

For more granular control over which of RuboCop's rules are enabled for your project, both from this gem and your own configs, consider using the DisabledByDefault: true option under AllCops in your project's .rubocop.yml file. This will disable all cops by default, and you can then explicitly enable the ones you want by setting Enabled: true. See the RuboCop docs for more information.

If you are using a rubocop version < 1.0.0, you can use rubocop-github version 0.16.2 (see the README from that version for more details).

bundle install
bundle exec rake test

All cops are located under lib/rubocop/cop/github.
