| description.long | Prettier is a code formatting tool that parses source code and reprints it with its own consistent style rules. It integrates with editors and CI systems to format code automatically on save or in version control workflows, reducing style-related code review discussions. | A fast Python linter built in Rust that consolidates multiple linting tools into a single interface. It supports over 500 rules, provides automated fixes for common issues, and runs significantly faster than traditional Python linters on even very large codebases. |
