The Ruby Linter/Formatter that Serves and Protects View on GitHub Read Docs Style Guide Overview RuboCop is a Ruby code style checker (linter) and formatter based on the community-driven Ruby Style Guide. RuboCop is extremely flexible and most aspects of its behavior can be tweaked via various configuration options. In practice RuboCop supports pretty much every (reasonably popular) coding style that you can think of. Apart from reporting problems in your code, RuboCop can also automatically fix some of the problems for you. Installation RuboCop's installation is pretty standard: $ gem install rubocop If you'd rather install RuboCop using bundler, add a line for it in your Gemfile (but set the require option to false, as it is a standalone tool): gem 'rubocop', require: false Usage Running rubocop with no arguments will check all Ruby source files in the current directory: $ rubocop Alternatively you can specify a list of files and directories to check: $ rubocop app spec lib/something.rb You can emulate the behavior of ruby -wc as well: $ rubocop -l You can auto-correct offenses with rubocop -a: $ rubocop -a You can limit auto-correct to layout/formatting-related offenses with rubocop -x: $ rubocop -x RuboCop can do way more. Use -h to view all available command-line options. Compatibility RuboCop supports MRI 2.4+ and JRuby 9.2+. © 2012-2020 Bozhidar Batsov and RuboCop contributors
