RuboCop GitHub

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

Usage

Rubocop 0.68 removed performance cops and 0.72 removed Rails cops. However, upgrading rubocop-github without modification will almost definitely create very many new offenses. The current version of this gem exposes the "legacy" configuration under config/default.yml and config/rails.yml which should be used if and only if the version of rubocop is locked to < 0.68 in your project (which it should be unless you bundle update rubocop). It also exposes an "edge" configuration under config/default_edge.yml and config/rails_edge.yml so that the changes can be tested without introducing breaking changes.

Legacy usage

Gemfile

gem "rubocop", "< 0.68"
gem "rubocop-github"

.rubocop.yml

inherit_gem:
  rubocop-github:
    - config/default.yml
    - config/rails.yml

Edge usage

Gemfile

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

.rubocop.yml

inherit_gem:
  rubocop-github:
    - config/default_edge.yml
    - config/rails_edge.yml

Testing

bundle install bundle exec rake test
