Query metadata from sdists / bdists / installed packages.

Project description

pkginfo README

This package provides an API for querying the distutils metadata written in the PKG-INFO file inside a source distribution (an sdist) or a binary distribution (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 develop).

Please see the pkginfo docs for detailed documentation.

1.1 (2013-10-09)

  • Fix tests to pass with current PyPy releases.

1.1b1 (2013-05-05)

0.9.1 (2012-10-22)

  • Fix test failure under Python >= 2.7, which is enforcing ‘metadata_version == 1.1’ because we have classifiers.

0.9 (2012-04-25)

0.8 (2011-03-12)

0.7 (2010-11-04)

  • Preserve newlines in the description field. Thanks to Sridhar Ratnakumar for the patch.

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

  • Remove bogus testing dependency on zope.testing.

  • Add tests that the “environment markers” spelled out in the approved PEP 345 are captured.

  • 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 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.
