Reusable core utilities for various Python Packaging
|
|
`interoperability specifications <https://packaging.python.org/specifications/>`_.
|
|
|
|
This library provides utilities that implement the interoperability
|
|
specifications which have clearly one correct behaviour (eg: :pep:`440`)
|
|
or benefit greatly from having a single shared implementation (eg: :pep:`425`).
|
|
|
|
.. end-intro
|
|
|
|
The ``packaging`` project includes the following: version handling, specifiers,
|
|
markers, requirements, tags, utilities.
|
|
|
|

Changelog
|
|
---------
|
|
|
|
20.8 - 2020-12-11
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
* Revert back to setuptools for compatibility purposes for some Linux distros (`#363 <https://github.com/pypa/packaging/issues/363>`__)
|
|
* Do not insert an underscore in wheel tags when the interpreter version number
|
|
is more than 2 digits (`#372 <https://github.com/pypa/packaging/issues/372>`__)
|
|
|
|
20.7 - 2020-11-28

|
|
|
|
* Use appropriate fallbacks for CPython ABI tag (`#181 <https://github.com/pypa/packaging/issues/181>`__, `#185 <https://github.com/pypa/packaging/issues/185>`__)

* Better handling of file URLs
|
|
|
|
This allows for using ``file:///absolute/path``, which was previously
|
|
prevented due to the missing ``netloc``.
|
|
|
|
This allows for all file URLs that ``urlunparse`` turns back into the
|
|
original URL to be valid.

|
|
* Add ``Version().is_devrelease`` and ``LegacyVersion().is_devrelease`` to
|
|
make it easy to determine if a release is a development release.
|
|
|
|
* Add ``utils.canonicalize_version`` to canonicalize version strings or
|
|
``Version`` instances (`#121 <https://github.com/pypa/packaging/issues/121>`__).
|
|
|
|
|
|
16.8 - 2016-10-29

|
|
~~~~~~~~~~~~~~~~~
|
|
|

|
|
make it easy to determine if a release is a post release.
|
|
|
|
* Add ``Version().base_version`` and ``LegacyVersion().base_version`` to make
|
|
it easy to get the public version without any pre or post release markers.
|
|
|
|
* Support the update to PEP 440 which removed the implied ``!=V.*`` when using
|
|
either ``>V`` or ``<V`` and which instead special cased the handling of

pre-releases, post-releases, and local versions when using ``>V`` or ``<V``.
|
|
|
|
|
|
14.5 - 2014-12-17

|
|
|
14.3 - 2014-11-19
|
|
~~~~~~~~~~~~~~~~~
|
|

|
* **BACKWARDS INCOMPATIBLE** Refactor specifier support so that it can sanely
|
|
handle legacy specifiers as well as PEP 440 specifiers.
|
|
|
|
* **BACKWARDS INCOMPATIBLE** Move the specifier support out of
|
|
``packaging.version`` into ``packaging.specifiers``.
|
|
|
|
|
|
14.2 - 2014-09-10
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
* Add prerelease support to ``Specifier``.
|
|
* Remove the ability to do ``item in Specifier()`` and replace it with
|
|
``Specifier().contains(item)`` in order to allow flags that signal if a
|
|
prerelease should be accepted or not.
|
|
* Add a method ``Specifier().filter()`` which will take an iterable and returns
|
|
an iterable with items that do not match the specifier filtered out.

|
|
validity.
|
|
|
|
|
|
14.0 - 2014-09-05
|
|
~~~~~~~~~~~~~~~~~
