``pkginfo2`` README
=====================

SPDX-License-Identifier: MIT
This package provides an API for querying the distutils metadata written in
the ``PKG-INFO`` file inside a source distriubtion (an ``sdist``) or a
binary distribution or a wheel (e.g., created by running ``bdist_egg``). It can
also query the ``EGG-INFO`` directory of an installed distribution, and
the ``*.egg-info`` stored in a "development checkout"
(e.g, created by running ``setup.py develop``), or the ``*.dist-info`` from
an as-installed package.
This is a fork of http://bazaar.launchpad.net/~tseaver/pkginfo removing the
ability to import and eval arbitrary code and work with modules known to the
current interpreter. Use importlib_metadata for this if you need it.
Please see the `pkginfo2 repo at <https://github.com/nexB/pkginfo2>`_
for more documentation.

- Replace use of ``StringIO.StringIO`` with ``io.StringIO``, where available
(Python >= 2.6).

available (Python >= 2.5). Ensured that distributions "unfold" wrapped
continuation lines, stripping any leading / trailing whitespace, no matter
which module was used for parsing.
- Remove bogus testing dependency on ``zope.testing``.
- Add tests that the "environment markers" spelled out in the approved
PEP 345 are captured.
- Add ``Project-URL`` for ``1.2`` PKG-INFO metdata (defined in the accepted
version of PEP 345).
0.5 (2009-09-11)
----------------
- Marked package as non-zip-safe.
- Fix Trove metadata misspelling.
- Restore compatibility with Python 2.4.
- Note that the introspection of installed packages / modules works only
in Python 2.6 or later.
- Add ``Index`` class as an abstraction over a collection of distributions.
- Add ``download_url_prefix`` argument to ``pkginfo`` script. If passed,
the script will use the prefix to synthesize a ``download_url`` for
distributions which do not supply that value directly.
0.4.1 (2009-05-07)
------------------
- Fix bugs in handling of installed packages which lack ``__file__``
or ``PKG-INFO``.
0.4 (2009-05-07)
----------------
- Extend the console script to allow output as CSV or INI. Also, added
arguments to specify the metadata version and other parsing / output
policies.
- Add support for the different metadata versions specified in PEPs
241, 314, and 345. Distributions now parse and expose only the attributes
corresponding to their metadata version, which defaults to the version
parsed from the ``PKG-INFO`` file. The programmer can override that version
when creating the distribution object.
0.3 (2009-05-07)
----------------
- Add support for introspection of "development eggs" (checkouts with
``PKG-INFO``, perhaps created via ``setup.py develop``).
- Add a console script, ``pkginfo``, which takes one or more paths
on the command line and writes out the associated information. Thanks
to ``runeh`` for the patch!
- Add ``get_metadata`` helper function, which dispatches a given path or
module across the available distribution types, and returns a distribution
object. Thanks to ``runeh`` for the patch!
- Make distribution objects support iteration over the metadata fields.
Thanks to ``runeh`` for the patch!
- Make ``Distribution`` and subclasses new-style classes. Thanks to ``runeh``
for the patch!
0.2 (2009-04-14)
----------------
- Add support for introspection of ``bdist_egg`` binary distributions.
0.1.1 (2009-04-10)
------------------
- Fix packaging errors.
0.1 (2009-04-10)
----------------
- Initial release.
