Lints are categorized by severity (correctness, suspicious, style, complexity, performance) and can be enabled or disabled individually. | RuboCop is an open-source Ruby linter and formatter that enforces code style based on the Ruby community style guide. It detects code quality issues and can automatically fix many of them, with extensive configuration options and extensibility through community plugins. |
