By using this decorator on functions or classes you achieve the same goal as by filling ``__all__`` variables manually, you just do not have to repeat yourself (object's name). You also know if object is public at definition site, not at some random location (where ``__all__`` was set). Note that in multiple decorator setup (in almost all cases) ``@public`` decorator must be applied before any other decorators, because it relies on the pointer to object's global namespace. If you apply other decorators first, ``@public`` may end up modifying the wrong namespace. Examples ======== >>> from sympy.utilities.decorator import public >>> __all__ # noqa: F821 Traceback (most recent call last): ...

This decorator should be used if an entire function or class is deprecated. If only a certain functionality is deprecated, you should use :func:`~.warns_deprecated_sympy` directly. This decorator is just a convenience. There is no functional difference between using this decorator and calling ``warns_deprecated_sympy()`` at the top of the function. The decorator takes the same arguments as :func:`~.warns_deprecated_sympy`. See its documentation for details on what the keywords to this decorator do. See the :ref:`deprecation-policy` document for details on when and how things should be deprecated in SymPy. Examples ======== >>> from sympy.utilities.decorator import deprecated >>> from sympy import simplify >>> @deprecated(""" ... The simplify_this(expr) function is deprecated. Use simplify(expr) ... instead.""", deprecated_since_version="1.1", ... active_deprecations_target='simplify-this-deprecation') ... def simplify_this(expr): ... """ ...
