RuboCop is a Ruby static code analyzer (linter) and code formatter that enforces the community Ruby Style Guide. It can automatically fix many offenses and is highly configurable and extensible with custom cops and plugins.

Use cases

• lint ruby code
• auto-format ruby files
• enforce a ruby style guide across a team
• automatically fix style offenses in a ruby project
• integrate ruby linting into CI
• run a ruby linter from my editor via LSP
• customize linting rules for different parts of a codebase

When to choose

• you write Ruby and want consistent, community-standard code style
• you want a linter and formatter in one tool with autocorrection
• you need editor integration via LSP or CI-friendly output formatters
• you want an extensible linter with plugins like rubocop-rails and rubocop-rspec

When to avoid

• you lint languages other than Ruby
• you want a formatter with a radically different style philosophy than the Ruby community guide
• you need runtime type checking or full static type analysis rather than style linting
