To see what dependencies are required to run the tests manually, please look at the ``noxfile.py`` file. Running tests ~~~~~~~~~~~~~ The packaging unit tests are found in the ``tests/`` directory and are designed to be run using `pytest`_. `pytest`_ will discover the tests automatically, so all you have to do is: .. code-block:: console $ python -m pytest ... 29204 passed, 4 skipped, 1 xfailed in 83.98 seconds This runs the tests with the default Python interpreter. This also allows you to run select tests instead of the entire test suite. You can also verify that the tests pass on other supported Python interpreters. For this we use `nox`_, which will automatically create a `virtualenv`_ for each supported Python version and run the tests. For example: .. code-block:: console $ nox -s tests ... nox > Ran multiple sessions: nox > * tests-3.6: success nox > * tests-3.7: success nox > * tests-3.8: success nox > * tests-3.9: success nox > * tests-pypy3: skipped You may not have all the required Python versions installed, in which case you will see one or more ``InterpreterNotFound`` errors. Running linters ~~~~~~~~~~~~~~~ If you wish to run the linting rules, you may use `pre-commit`_ or run ``nox -s lint``. .. code-block:: console $ nox -s lint ... nox > Session lint was successful. Building documentation ~~~~~~~~~~~~~~~~~~~~~~ packaging documentation is stored in the ``docs/`` directory. It is written in `reStructured Text`_ and rendered using `Sphinx`_. Use `nox`_ to build the documentation. For example: .. code-block:: console $ nox -s docs ... nox > Session docs was successful.

We only ask that you try and think carefully, ask questions and are `excellent to one another`_. Code review is our opportunity to share knowledge, design ideas and make friends. When reviewing a patch try to keep each of these concepts in mind: Architecture ------------ * Is the proposed change being made in the correct place? Intent ------ * What is the change being proposed? * Do we want this feature or is the bug they're fixing really a bug? Implementation -------------- * Does the change do what the author claims? * Are there sufficient tests? * Has it been documented? * Will this change introduce new bugs? Grammar and style ----------------- These are small things that are not caught by the automated style checkers. * Does a variable need a better name? * Should this be a keyword argument? .. _`excellent to one another`: https://speakerdeck.com/ohrite/better-code-review ././@PaxHeader0000000000000000000000000000002600000000000010213 xustar0022 mtime=1624128339.0 packaging-21.3/docs/development/submitting-patches.rst0000644000076500000240000000471000000000000023404 0ustar00brettcannonstaffSubmitting patches ================== * Always make a new branch for your work. * Patches should be small to facilitate easier review. `Studies have shown`_ that review quality falls off as patch size grows. Sometimes this will result in many small PRs to land a single large feature. * Larger changes should be discussed in a ticket before submission. * New features and significant bug fixes should be documented in the :doc:`/changelog`. * You must have legal permission to distribute any code you contribute and it must be available under both the BSD and Apache Software License Version 2.0 licenses.

Usage ----- .. doctest:: >>> from packaging.specifiers import SpecifierSet >>> from packaging.version import Version >>> spec1 = SpecifierSet("~=1.0") >>> spec1 >>> spec2 = SpecifierSet(">=1.0") >>> spec2 =1.0')> >>> # We can combine specifiers >>> combined_spec = spec1 & spec2 >>> combined_spec =1.0,~=1.0')> >>> # We can also implicitly combine a string specifier >>> combined_spec &= "!=1.1" >>> combined_spec =1.0,~=1.0')> >>> # Create a few versions to check for contains. >>> v1 = Version("1.0a5") >>> v2 = Version("1.0") >>> # We can check a version object to see if it falls within a specifier >>> v1 in combined_spec False >>> v2 in combined_spec True >>> # We can even do the same with a string based version >>> "1.4" in combined_spec True >>> # Finally we can filter a list of versions to get only those which are >>> # contained within our specifier. >>> list(combined_spec.filter([v1, v2, "1.4"])) [, '1.4'] Reference --------- .. class:: SpecifierSet(specifiers="", prereleases=None) This class abstracts handling specifying the dependencies of a project. It can be passed a single specifier (``>=3.0``), a comma-separated list of specifiers (``>=3.0,!=3.1``), or no specifier at all. Each individual specifier will be attempted to be parsed as a PEP 440 specifier (:class:`Specifier`) or as a legacy, setuptools style specifier (deprecated :class:`LegacySpecifier`). You may combine :class:`SpecifierSet` instances using the ``&`` operator (``SpecifierSet(">2") & SpecifierSet("<4")``). Both the membership tests and the combination support using raw strings in place of already instantiated objects. :param str specifiers: The string representation of a specifier or a comma-separated list of specifiers which will be parsed and normalized before use. :param bool prereleases: This tells the SpecifierSet if it should accept prerelease versions if applicable or not. The default of ``None`` will autodetect it from the given specifiers. :raises InvalidSpecifier: If the given ``specifiers`` are not parseable than this exception will be raised. .. attribute:: prereleases A boolean value indicating whether this :class:`SpecifierSet` represents a specifier that includes a pre-release versions. This can be set to either ``True`` or ``False`` to explicitly enable or disable prereleases or it can be set to ``None`` (the default) to enable autodetection. .. method:: __contains__(version) This is the more Pythonic version of :meth:`contains()`, but does not allow you to override the ``prereleases`` argument. If you need that, use :meth:`contains()`. See :meth:`contains()`. .. method:: contains(version, prereleases=None) Determines if ``version``, which can be either a version string, a :class:`Version`, or a deprecated :class:`LegacyVersion` object, is contained within this set of specifiers. This will either match or not match prereleases based on the ``prereleases`` parameter. When ``prereleases`` is set to ``None`` (the default) it will use the ``Specifier().prereleases`` attribute to determine if to allow them. Otherwise it will use the boolean value of the passed in value to determine if to allow them or not. .. method:: __len__() Returns the number of specifiers in this specifier set. .. method:: __iter__() Returns an iterator over all the underlying :class:`Specifier` (or deprecated :class:`LegacySpecifier`) instances in this specifier set. .. method:: filter(iterable, prereleases=None) Takes an iterable that can contain version strings, :class:`~.Version`, and deprecated :class:`~.LegacyVersion` instances and will then filter it, returning an iterable that contains only items which match the rules of this specifier object. This method is smarter than just ``filter(Specifier().contains, [...])`` because it implements the rule from PEP 440 where a prerelease item SHOULD be accepted if no other versions match the given specifier. The ``prereleases`` parameter functions similarly to that of the same parameter in ``contains``. If the value is ``None`` (the default) then it will intelligently decide if to allow prereleases based on the specifier, the ``Specifier().prereleases`` value, and the PEP 440 rules. Otherwise it will act as a boolean which will enable or disable all prerelease versions from being included. .. class:: Specifier(specifier, prereleases=None) This class abstracts the handling of a single `PEP 440`_ compatible specifier. It is generally not required to instantiate this manually, preferring instead to work with :class:`SpecifierSet`. :param str specifier: The string representation of a specifier which will be parsed and normalized before use. :param bool prereleases: This tells the specifier if it should accept prerelease versions if applicable or not. The default of ``None`` will autodetect it from the given specifiers. :raises InvalidSpecifier: If the ``specifier`` does not conform to PEP 440 in any way then this exception will be raised. .. attribute:: operator The string value of the operator part of this specifier. .. attribute:: version The string version of the version part of this specifier. .. attribute:: prereleases See :attr:`SpecifierSet.prereleases`. .. method:: __contains__(version) See :meth:`SpecifierSet.__contains__()`. .. method:: contains(version, prereleases=None) See :meth:`SpecifierSet.contains()`. .. method:: filter(iterable, prereleases=None) See :meth:`SpecifierSet.filter()`. .. class:: LegacySpecifier(specifier, prereleases=None) .. deprecated:: 20.5 Use :class:`Specifier` instead. This class abstracts the handling of a single legacy, setuptools style specifier. It is generally not required to instantiate this manually, preferring instead to work with :class:`SpecifierSet`. :param str specifier: The string representation of a specifier which will be parsed and normalized before use. :param bool prereleases: This tells the specifier if it should accept prerelease versions if applicable or not. The default of ``None`` will autodetect it from the given specifiers. :raises InvalidSpecifier: If the ``specifier`` is not parseable then this will be raised. .. attribute:: operator The string value of the operator part of this specifier. .. attribute:: version The string version of the version part of this specifier. .. attribute:: prereleases See :attr:`SpecifierSet.prereleases`. .. method:: __contains__(version) See :meth:`SpecifierSet.__contains__()`. .. method:: contains(version, prereleases=None) See :meth:`SpecifierSet.contains()`. .. method:: filter(iterable, prereleases=None) See :meth:`SpecifierSet.filter()`. .. exception:: InvalidSpecifier Raised when attempting to create a :class:`Specifier` with a specifier string that does not conform to `PEP 440`_. .. _`PEP 440`: https://www.python.org/dev/peps/pep-0440/ ././@PaxHeader0000000000000000000000000000002600000000000010213 xustar0022 mtime=1637079931.0 packaging-21.3/docs/tags.rst0000644000076500000240000002025300000000000016206 0ustar00brettcannonstaffTags ==== .. currentmodule:: packaging.tags Wheels encode the Python interpreter, ABI, and platform that they support in their filenames using `platform compatibility tags`_. This module provides support for both parsing these tags as well as discovering what tags the running Python interpreter supports. Usage ----- .. doctest:: >>> from packaging.tags import Tag, sys_tags >>> import sys >>> looking_for = Tag("py{major}".format(major=sys.version_info.major), "none", "any") >>> supported_tags = list(sys_tags()) >>> looking_for in supported_tags True >>> really_old = Tag("py1", "none", "any") >>> wheels = {really_old, looking_for} >>> best_wheel = None >>> for supported_tag in supported_tags: ... for wheel_tag in wheels: ... if supported_tag == wheel_tag: ... best_wheel = wheel_tag ... break >>> best_wheel == looking_for True Reference --------- High Level Interface '''''''''''''''''''' The following functions are the main interface to the library, and are typically the only items that applications should need to reference, in order to parse and check tags. .. class:: Tag(interpreter, abi, platform) A representation of the tag triple for a wheel. Instances are considered immutable and thus are hashable. Equality checking is also supported. :param str interpreter: The interpreter name, e.g. ``"py"`` (see :attr:`INTERPRETER_SHORT_NAMES` for mapping well-known interpreter names to their short names). :param str abi: The ABI that a wheel supports, e.g. ``"cp37m"``. :param str platform: The OS/platform the wheel supports, e.g. ``"win_amd64"``. .. attribute:: interpreter The interpreter name. .. attribute:: abi The supported ABI. .. attribute:: platform The OS/platform. .. function:: parse_tag(tag) Parses the provided ``tag`` into a set of :class:`Tag` instances. Returning a set is required due to the possibility that the tag is a `compressed tag set`_, e.g. ``"py2.py3-none-any"`` which supports both Python 2 and Python 3. :param str tag: The tag to parse, e.g. ``"py3-none-any"``. .. function:: sys_tags(*, warn=False) Yields the tags that the running interpreter supports. The iterable is ordered so that the best-matching tag is first in the sequence. The exact preferential order to tags is interpreter-specific, but in general the tag importance is in the order of: 1. Interpreter 2. Platform 3. ABI This order is due to the fact that an ABI is inherently tied to the platform, but platform-specific code is not necessarily tied to the ABI. The interpreter is the most important tag as it dictates basic support for any wheel. The function returns an iterable in order to allow for the possible short-circuiting of tag generation if the entire sequence is not necessary and tag calculation happens to be expensive. :param bool warn: Whether warnings should be logged. Defaults to ``False``. Low Level Interface ''''''''''''''''''' The following functions are low-level implementation details. They should typically not be needed in application code, unless the application has specialised requirements (for example, constructing sets of supported tags for environments other than the running interpreter). These functions capture the precise details of which environments support which tags. That information is not defined in the compatibility tag standards but is noted as being up to the implementation to provide. .. attribute:: INTERPRETER_SHORT_NAMES A dictionary mapping interpreter names to their `abbreviation codes`_ (e.g. ``"cpython"`` is ``"cp"``). All interpreter names are lower-case. .. function:: interpreter_name() Returns the running interpreter's name. This typically acts as the prefix to the :attr:`~Tag.interpreter` tag. .. function:: interpreter_version(*, warn=False) Returns the running interpreter's version. This typically acts as the suffix to the :attr:`~Tag.interpreter` tag. .. function:: mac_platforms(version=None, arch=None) Yields the :attr:`~Tag.platform` tags for macOS. :param tuple version: A two-item tuple presenting the version of macOS. Defaults to the current system's version. :param str arch: The CPU architecture. Defaults to the architecture of the current system, e.g. ``"x86_64"``. .. note:: Equivalent support for the other major platforms is purposefully not provided: - On Windows, platform compatibility is statically specified - On Linux, code must be run on the system itself to determine compatibility .. function:: platform_tags(version=None, arch=None) Yields the :attr:`~Tag.platform` tags for the running interpreter. .. function:: compatible_tags(python_version=None, interpreter=None, platforms=None) Yields the tags for an interpreter compatible with the Python version specified by ``python_version``. The specific tags generated are: - ``py*-none-`` - ``-none-any`` if ``interpreter`` is provided - ``py*-none-any`` :param Sequence python_version: A one- or two-item sequence representing the compatible version of Python. Defaults to ``sys.version_info[:2]``. :param str interpreter: The name of the interpreter (if known), e.g. ``"cp38"``. Defaults to the current interpreter. :param Iterable platforms: Iterable of compatible platforms. Defaults to the platforms compatible with the current system. .. function:: cpython_tags(python_version=None, abis=None, platforms=None, *, warn=False) Yields the tags for the CPython interpreter. The specific tags generated are: - ``cp--`` - ``cp-abi3-`` - ``cp-none-`` - ``cp-abi3-`` where "older version" is all older minor versions down to Python 3.2 (when ``abi3`` was introduced) If ``python_version`` only provides a major-only version then only user-provided ABIs via ``abis`` and the ``none`` ABI will be used. :param Sequence python_version: A one- or two-item sequence representing the targeted Python version. Defaults to ``sys.version_info[:2]``. :param Iterable abis: Iterable of compatible ABIs. Defaults to the ABIs compatible with the current system. :param Iterable platforms: Iterable of compatible platforms. Defaults to the platforms compatible with the current system. :param bool warn: Whether warnings should be logged. Defaults to ``False``. .. function:: generic_tags(interpreter=None, abis=None, platforms=None, *, warn=False) Yields the tags for an interpreter which requires no specialization. This function should be used if one of the other interpreter-specific functions provided by this module is not appropriate (i.e. not calculating tags for a CPython interpreter). The specific tags generated are: - ``--`` The ``"none"`` ABI will be added if it was not explicitly provided. :param str interpreter: The name of the interpreter. Defaults to being calculated. :param Iterable abis: Iterable of compatible ABIs. Defaults to the ABIs compatible with the current system. :param Iterable platforms: Iterable of compatible platforms. Defaults to the platforms compatible with the current system. :param bool warn: Whether warnings should be logged. Defaults to ``False``. .. _`abbreviation codes`: https://www.python.org/dev/peps/pep-0425/#python-tag .. _`compressed tag set`: https://www.python.org/dev/peps/pep-0425/#compressed-tag-sets .. _`platform compatibility tags`: https://packaging.python.org/specifications/platform-compatibility-tags/ ././@PaxHeader0000000000000000000000000000002600000000000010213 xustar0022 mtime=1611890020.0 packaging-21.3/docs/utils.rst0000644000076500000240000000543100000000000016411 0ustar00brettcannonstaffUtilities ========= .. currentmodule:: packaging.utils A set of small, helper utilities for dealing with Python packages.

Usage ----- .. doctest:: >>> from packaging.version import Version, parse >>> v1 = parse("1.0a5") >>> v2 = Version("1.0") >>> v1 >>> v2 >>> v1 < v2 True >>> v1.epoch 0 >>> v1.release (1, 0) >>> v1.pre ('a', 5) >>> v1.is_prerelease True >>> v2.is_prerelease False >>> Version("french toast") Traceback (most recent call last): ... InvalidVersion: Invalid version: 'french toast' >>> Version("1.0").post >>> Version("1.0").is_postrelease False >>> Version("1.0.post0").post 0 >>> Version("1.0.post0").is_postrelease True Reference --------- .. function:: parse(version) This function takes a version string and will parse it as a :class:`Version` if the version is a valid PEP 440 version, otherwise it will parse it as a deprecated :class:`LegacyVersion`. .. class:: Version(version) This class abstracts handling of a project's versions. It implements the scheme defined in `PEP 440`_. A :class:`Version` instance is comparison aware and can be compared and sorted using the standard Python interfaces. :param str version: The string representation of a version which will be parsed and normalized before use. :raises InvalidVersion: If the ``version`` does not conform to PEP 440 in any way then this exception will be raised. .. attribute:: public A string representing the public version portion of this ``Version()``. .. attribute:: base_version A string representing the base version of this :class:`Version` instance. The base version is the public version of the project without any pre or post release markers. .. attribute:: epoch An integer giving the version epoch of this :class:`Version` instance .. attribute:: release A tuple of integers giving the components of the release segment of this :class:`Version` instance; that is, the ``1.2.3`` part of the version number, including trailing zeroes but not including the epoch or any prerelease/development/postrelease suffixes .. attribute:: major An integer representing the first item of :attr:`release` or ``0`` if unavailable. .. attribute:: minor An integer representing the second item of :attr:`release` or ``0`` if unavailable. .. attribute:: micro An integer representing the third item of :attr:`release` or ``0`` if unavailable. .. attribute:: local A string representing the local version portion of this ``Version()`` if it has one, or ``None`` otherwise. .. attribute:: pre If this :class:`Version` instance represents a prerelease, this attribute will be a pair of the prerelease phase (the string ``"a"``, ``"b"``, or ``"rc"``) and the prerelease number (an integer). If this instance is not a prerelease, the attribute will be `None`. .. attribute:: is_prerelease A boolean value indicating whether this :class:`Version` instance represents a prerelease and/or development release. .. attribute:: dev If this :class:`Version` instance represents a development release, this attribute will be the development release number (an integer); otherwise, it will be `None`. .. attribute:: is_devrelease A boolean value indicating whether this :class:`Version` instance represents a development release. .. attribute:: post If this :class:`Version` instance represents a postrelease, this attribute will be the postrelease number (an integer); otherwise, it will be `None`. .. attribute:: is_postrelease A boolean value indicating whether this :class:`Version` instance represents a post-release. .. class:: LegacyVersion(version) .. deprecated:: 20.5 Use :class:`Version` instead. This class abstracts handling of a project's versions if they are not compatible with the scheme defined in `PEP 440`_. It implements a similar interface to that of :class:`Version`. This class implements the previous de facto sorting algorithm used by setuptools, however it will always sort as less than a :class:`Version` instance. :param str version: The string representation of a version which will be used as is. .. note:: :class:`LegacyVersion` instances are always ordered lower than :class:`Version` instances. >>> from packaging.version import Version, LegacyVersion >>> v1 = Version("1.0") >>> v2 = LegacyVersion("1.0") >>> v1 > v2 True >>> v3 = LegacyVersion("1.3") >>> v1 > v3 True Also note that some strings are still valid PEP 440 strings (:class:`Version`), even if they look very similar to other versions that are not (:class:`LegacyVersion`). Examples include versions with `Pre-release spelling`_ and `Post-release spelling`_. >>> from packaging.version import parse >>> v1 = parse('0.9.8a') >>> v2 = parse('0.9.8beta') >>> v3 = parse('0.9.8r') >>> v4 = parse('0.9.8rev') >>> v5 = parse('0.9.8t') >>> v1 >>> v1.is_prerelease True >>> v2 >>> v2.is_prerelease True >>> v3 >>> v3.is_postrelease True >>> v4 >>> v4.is_postrelease True >>> v5 >>> v5.is_prerelease False >>> v5.is_postrelease False .. attribute:: public A string representing the public version portion of this :class:`LegacyVersion`. This will always be the entire version string. .. attribute:: base_version A string representing the base version portion of this :class:`LegacyVersion` instance. This will always be the entire version string. .. attribute:: epoch This will always be ``-1`` since without `PEP 440`_ we do not have the concept of version epochs. The value reflects the fact that :class:`LegacyVersion` instances always compare less than :class:`Version` instances. .. attribute:: release This will always be ``None`` since without `PEP 440`_ we do not have the concept of a release segment or its components. It exists primarily to allow a :class:`LegacyVersion` to be used as a stand in for a :class:`Version`. .. attribute:: local This will always be ``None`` since without `PEP 440`_ we do not have the concept of a local version. It exists primarily to allow a :class:`LegacyVersion` to be used as a stand in for a :class:`Version`. .. attribute:: pre This will always be ``None`` since without `PEP 440`_ we do not have the concept of a prerelease. It exists primarily to allow a :class:`LegacyVersion` to be used as a stand in for a :class:`Version`. .. attribute:: is_prerelease A boolean value indicating whether this :class:`LegacyVersion` represents a prerelease and/or development release. Since without `PEP 440`_ there is no concept of pre or dev releases this will always be `False` and exists for compatibility with :class:`Version`. .. attribute:: dev This will always be ``None`` since without `PEP 440`_ we do not have the concept of a development release. It exists primarily to allow a :class:`LegacyVersion` to be used as a stand in for a :class:`Version`. .. attribute:: is_devrelease A boolean value indicating whether this :class:`LegacyVersion` represents a development release. Since without `PEP 440`_ there is no concept of dev releases this will always be `False` and exists for compatibility with :class:`Version`. .. attribute:: post This will always be ``None`` since without `PEP 440`_ we do not have the concept of a postrelease. It exists primarily to allow a :class:`LegacyVersion` to be used as a stand in for a :class:`Version`. .. attribute:: is_postrelease A boolean value indicating whether this :class:`LegacyVersion` represents a post-release. Since without `PEP 440`_ there is no concept of post-releases this will always be ``False`` and exists for compatibility with :class:`Version`. .. exception:: InvalidVersion Raised when attempting to create a :class:`Version` with a version string that does not conform to `PEP 440`_. .. data:: VERSION_PATTERN A string containing the regular expression used to match a valid version. The pattern is not anchored at either end, and is intended for embedding in larger expressions (for example, matching a version number as part of a file name). The regular expression should be compiled with the ``re.VERBOSE`` and ``re.IGNORECASE`` flags set. .. _PEP 440: https://www.python.org/dev/peps/pep-0440/ .. _Pre-release spelling : https://www.python.org/dev/peps/pep-0440/#pre-release-spelling .. _Post-release spelling : https://www.python.org/dev/peps/pep-0440/#post-release-spelling ././@PaxHeader0000000000000000000000000000002600000000000010213 xustar0022 mtime=1613160782.0 packaging-21.3/mypy.ini0000644000076500000240000000071600000000000015267 0ustar00brettcannonstaff[mypy] ignore_missing_imports = True # The following are the flags enabled by --strict warn_unused_configs = True disallow_subclassing_any = True disallow_any_generics = True disallow_untyped_calls = True disallow_untyped_defs = True disallow_incomplete_defs = True check_untyped_defs = True disallow_untyped_decorators = True no_implicit_optional = True warn_redundant_casts = True warn_unused_ignores = True warn_return_any = True no_implicit_reexport = True ././@PaxHeader0000000000000000000000000000003400000000000010212 xustar0028 mtime=1637195939.7556837 packaging-21.3/packaging/0000755000076500000240000000000000000000000015510 5ustar00brettcannonstaff././@PaxHeader0000000000000000000000000000002600000000000010213 xustar0022 mtime=1637195935.0 packaging-21.3/packaging/__about__.py0000644000076500000240000000122500000000000017770 0ustar00brettcannonstaff# This file is dual licensed under the terms of the Apache License, Version # 2.0, and the BSD License.

packaging
=========

.. start-intro

Reusable core utilities for various Python Packaging
`interoperability 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.

Documentation
-------------

The `documentation`_ provides information and the API for the following:

- Version Handling
- Specifiers
- Markers
- Requirements
- Tags
- Utilities

Installation
------------

Use ``pip`` to install these utilities::

    pip install packaging

Discussion
----------

If you run into bugs, you can file them in our `issue tracker`_.

You can also join ``#pypa`` on Freenode to ask questions or get involved.


.. _`documentation`: https://packaging.pypa.io/
.. _`issue tracker`: https://github.com/pypa/packaging/issues


Code of Conduct
---------------

Everyone interacting in the packaging project's codebases, issue trackers, chat
rooms, and mailing lists is expected to follow the `PSF Code of Conduct`_.

.. _PSF Code of Conduct: https://github.com/pypa/.github/blob/main/CODE_OF_CONDUCT.md

Contributing
------------

The ``CONTRIBUTING.rst`` file outlines how to contribute to this project as
well as how to report a potential security issue. The documentation for this
project also covers information about `project development`_ and `security`_.

  original URL to be valid.


18.0 - 2018-09-26
~~~~~~~~~~~~~~~~~

* Improve error messages when invalid requirements are given. (`#129 `__)


17.1 - 2017-02-28

* Define minimal pyparsing version to 2.0.2 (`#91 `__).

* Add ``epoch``, ``release``, ``pre``, ``dev``, and ``post`` attributes to
  ``Version`` and ``LegacyVersion`` (`#34 `__).

* 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 `__).


16.8 - 2016-10-29

~~~~~~~~~~~~~~~~~

* Fix a regression in parsing requirements with whitespaces between the comma
  separators.


16.4 - 2016-02-22
~~~~~~~~~~~~~~~~~

  ``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.


14.1 - 2014-09-08
~~~~~~~~~~~~~~~~~

* Allow ``LegacyVersion`` and ``Version`` to be sorted together.
* Add ``packaging.version.parse()`` to enable easily parsing a version string
  as either a ``Version`` or a ``LegacyVersion`` depending on it's PEP 440
  validity.


14.0 - 2014-09-05
~~~~~~~~~~~~~~~~~

* Initial release.
