pyproject-metadata

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).

Usage

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

from pyproject_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
