PEP 621 metadata parsing

Project description

pyproject-metadata status checks tests codecov Documentation Status

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:

from ptproject_metadata import StandardMetadata

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

pkg_info = metadata.as_rfc822()
print(str(pkg_info))  # core metadata
