"""A mypy_ plugin for managing a number of platform-specific annotations.
Its functionality can be split into three distinct parts:

* Assigning the (platform-dependent) precisions of certain `~numpy.number`
  subclasses, including the likes of `~numpy.int_`, `~numpy.intp` and
  `~numpy.longlong`. See the documentation on
  :ref:`scalar types <arrays.scalars.built-in>` for a comprehensive overview
  of the affected classes. Without the plugin the precision of all relevant
  classes will be inferred as `~typing.Any`.
* Removing all extended-precision `~numpy.number` subclasses that are
  unavailable for the platform in question. Most notably this includes the
  likes of `~numpy.float128` and `~numpy.complex256`. Without the plugin *all*
  extended-precision types will, as far as mypy is concerned, be available
  to all platforms.
* Assigning the (platform-dependent) precision of `~numpy.ctypeslib.c_intp`.
  Without the plugin the type will default to `ctypes.c_int64`.

  .. versionadded:: 1.22

Examples
--------
To enable the plugin, one must add it to their mypy `configuration file`_:

.. code-block:: ini

    [mypy]
    plugins = numpy.typing.mypy_plugin

.. _mypy: http://mypy-lang.org/
.. _configuration file: https://mypy.readthedocs.io/en/stable/config_file.html
