RuboCop GitHub

This repository provides recommended RuboCop configuration and additional Cops for use on GitHub open source and internal Ruby projects.

Usage

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_from:
  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.

Legacy usage

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).

Testing

bundle install
bundle exec rake test

The Cops

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