RuboCop's installation is pretty standard: $ gem install rubocop There are many other IDE options for Ruby on Rails developers like RubyMine (the enterprise version), Sublime, Vim, and so on. But my personal favorite is Visual Studio as it has extensive plugin support for multiple languages like Golang, PHP, Node.js, and more. 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 So its the default IDE, especially for polyglot developers. Running rubocop with no arguments will check all Ruby source files in the current directory: $ rubocopĪlternatively you can specify a list of files and directories to check: $ rubocop app spec lib/something.rb RUBYMINE RUBOCOP INSTALL You can emulate the behavior of ruby -wc as well: $ rubocop -l 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. You can limit auto-correct to layout/formatting-related offenses with rubocop -x: $ rubocop -x You can auto-correct offenses with rubocop -a: $ rubocop -a In practice RuboCop supports pretty much every (reasonably popular) coding style that you can think of.

If necessary, you can enable the Standard wrapper and use it for analyzing project sources. You can also check the entire project and display all RuboCop warnings in a single report. I’m Dockerizing the development environment for a legacy Rails monolith, using a Dockerfile written for local env + docker-compose using that image to start different services. RubyMine supports integration with RuboCop and enables you to fix its offenses right inside the IDE, for example, in the code editor.
