Dataclass for PEP 621 metadata with support for core metadata generation

This project does not implement the parsing of pyproject.toml containing PEP 621 metadata.

Instead, given a Python data structure representing PEP 621 metadata (already parsed), it will validate this input and generate a PEP 643-compliant metadata file (e.g. PKG-INFO).

After installing pyproject-metadata, you can use it as a library in your scripts and programs:

frompyproject_metadataimportStandardMetadataparsed_pyproject={... } # you can use parsers like `tomli` to obtain this dictmetadata=StandardMetadata.from_pyproject(parsed_pyproject) print(metadata.entrypoints) # same fields as defined in PEP 621pkg_info=metadata.as_rfc822() print(str(pkg_info)) # core metadata
