metadata_please

There are a couple of pretty decent ways to read metadata (importlib-metadata, and pkginfo) but they tend to be pretty heavyweight. This lib aims to do two things, with as minimal dependencies as possible:

1. Support just enough metadata to be able to look up deps.
2. Do "the thing that pip does" when deciding what dist-info dir to look at.

Usage

Example snippet to show how to get the metadata from a wheel.

from zipfile import ZipFile
from metadata_please import basic_metadata_from_wheel

zf = ZipFile('somepkg.whl')
print(basic_metadata_from_wheel(zf, "somepkg"))

Output

BasicMetadata(
    reqs=[
        'cli-helpers[styles] >=2.2.1',
        'click >=4.1',
        'configobj >=5.0.5',

highlighting.\n\n![Completion](screenshots/litecli.png)\n![CompletionGif](screenshots/litecli.gif)\n\n## Installation\n\nIf you already know how to install python
packages, then you can install it via pip:\n\nYou might need sudo on linux.\n\n```\n$ pip install -U litecli\n```\n\nThe package is also available on Arch Linux through
AUR in two versions: [litecli](https://aur.archlinux.org/packages/litecli/) is based the latest release (git tag) and
[litecli-git](https://aur.archlinux.org/packages/litecli-git/) is based on the master branch of the git repo. You can install them manually or with an AUR helper such as
`yay`:\n\n```\n$ yay -S litecli\n```\n\nor\n\n```\n$ yay -S litecli-git\n```\n\nFor MacOS users, you can also use Homebrew to install it:\n\n```\n$ brew install
litecli\n```\n\n## Usage\n\n```\n$ litecli --help\n\nUsage: litecli [OPTIONS] [DATABASE]\n\nExamples:\n  - litecli sqlite_db_name\n```\n\nA config file is automatically
created at `~/.config/litecli/config` at first launch. For Windows machines a config file is created at `~\\AppData\\Local\\dbcli\\litecli\\config` at first launch. See
the file itself for a description of all available options.\n\n## Docs\n\nVisit: [litecli.com/features](https://litecli.com/features)\n',

The metadata can be extracted from a wheel, sdist (zip or tarball) or a source checkout (best effort). Check __init__.py file for all available functions.

Version Compat

Usage of this library should work back to 3.7, but development (and mypy compatibility) only on 3.10-3.12. Linting requires 3.12 for full fidelity.
