Warning
********

.. warning::
   The authors of `pip`_ **do not condone** the use of this package. Relying on pip's
   internals is a **dangerous** idea for your software as they are broken intentionally
   and regularly.  This package may not always be completely updated up PyPI, so relying
   on it may break your code! User beware!

.. _pip: https://github.com/pypa/pip


Installation
*************

Install from `PyPI`_:

 .. code-block:: console

    $ pipenv install pip-shims

Install from `Github`_:

.. code-block:: console

    $ pipenv install -e git+https://github.com/sarugaku/pip-shims.git#egg=pip-shims

.. _`Summary`:

Summary
********

**pip-shims** is a set of compatibilty access shims to the `pip`_ internal API. **pip-shims**
provides compatibility across several pip releases.  The shims are provided using a lazy
import strategy by hacking a module by overloading a class instance's *getattr* method.
This library exists due to my constant writing of the same set of import shims across
many different libraries, including `pipenv`_, `pip-tools`_, `requirementslib`_, and
`passa`_.

.. _passa: https://github.com/sarugaku/passa
.. _pip: https://github.com/pypa/pip
.. _pipenv: https://github.com/pypa/pipenv
.. _pip-tools: https://github.com/jazzband/pip-tools
.. _requirementslib: https://github.com/sarugaku/requirementslib

Pip Compatibility
*****************

Due to the fact that pip has adopted `calver`_, this project provides shims for pip releases
up to 2 years. pip earlier than that period MAY work but the compatibility isn't guaranteed
by the continous integration. For example, the support for ``pip==20.0`` will be dropped at 1/1/2023.

.. _`Usage`:

Usage
******

Importing a shim
--------------------

You can use **pip-shims** to expose elements of **pip**'s internal API by importing them:

.. code-block:: pycon

    >>> from pip_shims import Wheel
    >>> mywheel = Wheel('/path/to/my/wheel.whl')


Resolving Dependencies
----------------------------

You can resolve the dependencies of a package using the shimmed resolver interface:

.. code-block:: pycon

    >>> from pip_shims.shims import resolve, InstallRequirement
    >>> ireq = InstallRequirement.from_line("requests>=2.20")
    >>> results = resolve(ireq)
    >>> for k, v in results.items():
    ...    print("{0}: {1!r}".format(k, v))
