By default, pip uses ``importlib.metadata`` on Python 3.11+, and ``pkg_resourcess`` otherwise. This can be overridden by a couple of ways: * If environment variable ``_PIP_USE_IMPORTLIB_METADATA`` is set, it dictates whether ``importlib.metadata`` is used, regardless of Python version. * On Python 3.11+, Python distributors can patch ``importlib.metadata`` to add a global constant ``_PIP_USE_IMPORTLIB_METADATA = False``. This makes pip use ``pkg_resources`` (unless the user set the aforementioned environment variable to *True*). �_PIP_USE_IMPORTLIB_METADATA)� � Fr NT) � contextlib�suppress�KeyError� ValueError�boolr �os�environ�sys� version_info�importlib.metadata�getattr�metadata�� importlib� r% ��/builddir/build/BUILDROOT/alt-python38-pip-22.2.1-2.el8.x86_64/opt/alt/python38/lib/python3.8/site-packages/pip/_internal/metadata/__init__.py� _should_use_importlib_metadata s $ r' c @ s& e Zd ZU ee ed< ee ed< dS )�Backend� Distribution� EnvironmentN)�__name__� __module__� __qualname__r r �__annotations__r r% r% r% r& r( 4 s r( )�maxsizec C s2 t � r ddlm} tt| �S ddlm} tt|�S )Nr r# )� pkg_resources)r' � r$ r r( r0 )r$ r0 r% r% r& r 9 s c C s t � j�� S )a Get the default representation for the current environment.
