| description.long | A type analysis tool for Python that enables code to transition from pure dynamic typing to statically-typed code through annotations, with error detection at check time. Code runs with negligible performance impact and developers can incrementally adopt static types in existing projects. | 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. |
