These are listed in ``dev-requirements.txt`` and they can be installed in a `virtualenv`_ using `pip`_. Once you've installed the dependencies, install packaging in ``editable`` mode. For example: .. code-block:: console $ # Create a virtualenv and activate it $ pip install --requirement dev-requirements.txt $ pip install --editable . You are now ready to run the tests and build the documentation. Running tests ~~~~~~~~~~~~~ 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 $ py.test ... 62746 passed in 220.43 seconds This runs the tests with the default Python interpreter. You can also verify that the tests pass on other supported Python interpreters. For this we use `tox`_, which will automatically create a `virtualenv`_ for each supported Python version and run the tests. For example: .. code-block:: console $ tox ... ERROR: py26: InterpreterNotFound: python2.6 py27: commands succeeded ERROR: pypy: InterpreterNotFound: pypy ERROR: py32: InterpreterNotFound: python3.2 py33: commands succeeded docs: commands succeeded pep8: commands succeeded You may not have all the required Python versions installed, in which case you will see one or more ``InterpreterNotFound`` errors. Building documentation ~~~~~~~~~~~~~~~~~~~~~~ packaging documentation is stored in the ``docs/`` directory. It is written in `reStructured Text`_ and rendered using `Sphinx`_. Use `tox`_ to build the documentation. For example: .. code-block:: console $ tox -e docs ... docs: commands succeeded congratulations :) The HTML documentation index can now be found at ``docs/_build/html/index.html``. .. _`pytest`: https://pypi.python.org/pypi/pytest .. _`tox`: https://pypi.python.org/pypi/tox .. _`virtualenv`: https://pypi.python.org/pypi/virtualenv .. _`pip`: https://pypi.python.org/pypi/pip .. _`sphinx`: https://pypi.python.org/pypi/Sphinx .. _`reStructured Text`: http://sphinx-doc.org/rest.htmlpackaging-16.8/docs/development/index.rst0000644000076500000240000000101213005143116021275 0ustar dstufftstaff00000000000000Development =========== As an open source project, packaging welcomes contributions of all forms. The sections below will help you get started. File bugs and feature requests on our issue tracker on `GitHub`_. If it is a bug check out `what to put in your bug report`_. .. toctree:: :maxdepth: 2 getting-started submitting-patches reviewing-patches .. _`GitHub`: https://github.com/pypa/packaging .. _`what to put in your bug report`: http://www.contribution-guide.org/#what-to-put-in-your-bug-report packaging-16.8/docs/development/reviewing-patches.rst0000644000076500000240000000176513005143116023631 0ustar dstufftstaff00000000000000Reviewing and merging patches ============================= Everyone is encouraged to review open pull requests. 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-reviewpackaging-16.8/docs/development/submitting-patches.rst0000644000076500000240000000516413005143116024014 0ustar dstufftstaff00000000000000Submitting 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. If you believe you've identified a security issue in packaging, please follow the directions on the :doc:`security page `. Code ---- When in doubt, refer to :pep:`8` for Python code. You can check if your code meets our automated requirements by running ``flake8`` against it. If you've installed the development requirements this will automatically use our configuration. You can also run the ``tox`` job with ``tox -e pep8``. `Write comments as complete sentences.`_ Every code file must start with the boilerplate licensing notice: .. code-block:: python # This file is dual licensed under the terms of the Apache License, Version # 2.0, and the BSD License. See the LICENSE file in the root of this repository # for complete details. Additionally, every Python code file must contain .. code-block:: python from __future__ import absolute_import, division, print_function Tests ----- All code changes must be accompanied by unit tests with 100% code coverage (as measured by the combined metrics across our build matrix). Documentation ------------- All features should be documented with prose in the ``docs`` section. When referring to a hypothetical individual (such as "a person receiving an encrypted message") use gender neutral pronouns (they/them/their). Docstrings are typically only used when writing abstract classes, but should be written like this if required: .. code-block:: python def some_function(some_arg): """ Does some things. :param some_arg: Some argument. """ So, specifically: * Always use three double quotes. * Put the three double quotes on their own line. * No blank line at the end. * Use Sphinx parameter/attribute documentation `syntax`_. .. _`Write comments as complete sentences.`: http://nedbatchelder.com/blog/201401/comments_should_be_sentences.html .. _`syntax`: http://sphinx-doc.org/domains.html#info-field-lists .. _`Studies have shown`: http://www.ibm.com/developerworks/rational/library/11-proven-practices-for-peer-review/ packaging-16.8/docs/index.rst0000644000076500000240000000063013005143116016760 0ustar dstufftstaff00000000000000Welcome to packaging ==================== Core utilities for Python packages Installation ------------ You can install packaging with ``pip``: .. code-block:: console $ pip install packaging API --- .. toctree:: :maxdepth: 1 version specifiers markers requirements utils Project ------- .. toctree:: :maxdepth: 2 development/index security changelog packaging-16.8/docs/Makefile0000644000076500000240000001270713005143116016567 0ustar dstufftstaff00000000000000# Makefile for Sphinx documentation # # You can set these variables from the command line.

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 be attempted to be parsed as a PEP 440 specifier (:class:`Specifier`) or as a legacy, setuptools style specifier (: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 :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 :class:`LegacySpecifier`) instances in this specifier set. .. method:: filter(iterable, prereleases=None) Takes an iterable that can contain version strings, :class:`Version`, and :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) 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/ packaging-16.8/docs/utils.rst0000644000076500000240000000113013005143116017005 0ustar dstufftstaff00000000000000Utilities ========= .. currentmodule:: packaging.utils A set of small, helper utilities for dealing with Python packages. Reference --------- .. function:: canonicalize_name(name) This function takes a valid Python package name, and returns the normalized form of it. :param str name: The name to normalize. .. doctest:: >>> from packaging.utils import canonicalize_name >>> canonicalize_name("Django") 'django' >>> canonicalize_name("oslo.concurrency") 'oslo-concurrency' >>> canonicalize_name("requests") 'requests' packaging-16.8/docs/version.rst0000644000076500000240000001117213005143116017341 0ustar dstufftstaff00000000000000Version Handling ================ .. currentmodule:: packaging.version A core requirement of dealing with packages is the ability to work with versions. `PEP 440`_ defines the standard version scheme for Python packages which has been implemented by this module. Usage ----- .. doctest:: >>> from packaging.version import Version, parse >>> v1 = parse("1.0a5") >>> v2 = Version("1.0") >>> v1 >>> v2 >>> v1 < v2 True >>> v1.is_prerelease True >>> v2.is_prerelease False >>> Version("french toast") Traceback (most recent call last): ... InvalidVersion: Invalid version: 'french toast' >>> Version("1.0").is_postrelease False >>> 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 :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:: local A string representing the local version portion of this ``Version()`` if it has one, or ``None`` otherwise. .. attribute:: is_prerelease A boolean value indicating whether this :class:`Version` instance represents a prerelease or a final release. .. attribute:: is_postrelease A boolean value indicating whether this :class:`Version` instance represents a post-release. .. class:: LegacyVersion(version) 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. .. 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:: 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:: is_prerelease A boolean value indicating whether this :class:`LegacyVersion` represents a prerelease or a final release. Since without `PEP 440`_ there is no concept of pre or final releases this will always be `False` and exists for compatibility with :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/ packaging-16.8/LICENSE0000644000076500000240000000030513005143116015173 0ustar dstufftstaff00000000000000This software is made available under the terms of *either* of the licenses found in LICENSE.APACHE or LICENSE.BSD.

        * Fix markers that utilize ``in`` so that they render correctly.
        
        * Fix an erroneous test on Python RC releases.
        
        
        16.7 - 2016-04-23
        ~~~~~~~~~~~~~~~~~
        
        * Add support for the deprecated ``python_implementation`` marker which was
          an undocumented setuptools marker in addition to the newer markers.
        
        
        16.6 - 2016-03-29
        ~~~~~~~~~~~~~~~~~

          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
