A guide for writing and maintaining Ruby and Rails applications
Follow the Ruby Style Guide and enforce it via static analysis tools such as Code Climate and Rubocop. You can copy the recommended Rubocop configuration in your Ruby project and make any changes based on your team’s preferences.
Note that the Rubocop configuration linked above only includes settings that differ from the default configuration. We tend to agree with most of the default settings.
Style Rubocop setting provides multiple options, at least one
option must be chosen. A cop that supports different styles must never be
disabled outright. The point is to pick one style and use it consistently.
