It handles common refactoring tasks such as replacing the Config class with model_config, updating Field parameters, converting validators to their V2 equivalents, and replacing deprecated constraint functions with Annotated types. The tool uses libcst for safe AST-based code transformation and provides a --diff flag to preview changes before applying them.\n\nThe tool is designed for developers maintaining Pydantic V1 projects who need to upgrade to V2 but face large codebases where manual refactoring is impractical. It covers the majority of straightforward migration patterns, though complex custom types and protocol functions may require manual follow-up (flagged with TODO comments). The project is archived and no longer actively maintained, so it will not evolve with future Pydantic V2 releases.","worth_installing":"Yes, if you have a Pydantic V1 codebase to migrate and need to automate routine refactoring tasks. The tool handles the majority of straightforward patterns and is low-friction to install. However, be aware that the project is archived and no longer maintained\u2014it will not adapt to new Pydantic V2 features or Python versions, and complex migrations may still require manual work. Use it as a starting point rather than a complete solution."},"id":"bump-pydantic","links":{"html":"https://skillfed.io/packages/bump-pydantic","md":"https://skillfed.io/packages/bump-pydantic.md","pypi":"https://pypi.org/project/bump-pydantic/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2023-12-28","license_spdx":null,"license_treatment":"permissive","name":"bump-pydantic","python_support":"supports_current","summary":"Convert Pydantic from V1 to V2 \u267b"},"popularity":{"monthly_downloads":229283,"position":9134,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.8.0"}
