distinfo is a library for extracting metadata from Python distributions.
It includes standard metadata per Python Metadata 2.1 plus an extra attribute, "ext", for extended metadata. Metadata is collected from:
- parsing of pyproject.toml, if dynamic also by calling PEP517 hook "prepare_metadata_for_build_wheel"
- execution of the setup.py script
- dist and egg info directories
Print requirements and metadata:
>>> import distinfo
>>>
>>> dist = await distinfo.from_path("/path/to/package/source")
>>> distinfo.dump(dist)
