Deprecated Library

Deprecated is Easy to Use


If you need to mark a function or a method as deprecated,
you can use the ``@deprecated`` decorator:

Save in a hello.py:

.. code:: python

    from deprecated import deprecated


    @deprecated(version='1.2.1', reason="You should use another function")
    def some_old_function(x, y):
        return x + y


    class SomeClass(object):
        @deprecated(version='1.3.0', reason="This method is deprecated")
        def some_old_method(self, x, y):
            return x + y


    some_old_function(12, 34)
    obj = SomeClass()
    obj.some_old_method(5, 8)


And Easy to Setup
`````````````````

And run it:

.. code:: bash

    $ pip install Deprecated
    $ python hello.py
    hello.py:15: DeprecationWarning: Call to deprecated function (or staticmethod) some_old_function.
    (You should use another function) -- Deprecated since version 1.2.0.
      some_old_function(12, 34)
    hello.py:17: DeprecationWarning: Call to deprecated method some_old_method.
    (This method is deprecated) -- Deprecated since version 1.3.0.
      obj.some_old_method(5, 8)


You can document your code

Have you ever wonder how to document that some functions, classes, methods, etc. are deprecated? This is now possible with the integrated Sphinx directives:

For instance, in hello_sphinx.py:

.. code:: python

from deprecated.sphinx import deprecated
from deprecated.sphinx import versionadded
from deprecated.sphinx import versionchanged


@versionadded(version='1.0', reason="This function is new")
def function_one():
    '''This is the function one'''


@versionchanged(version='1.0', reason="This function is modified")
def function_two():
    '''This is the function two'''


@deprecated(version='1.0', reason="This function will be removed soon")
def function_three():
    '''This is the function three'''


function_one()
function_two()
function_three()  # warns

help(function_one)
help(function_two)
help(function_three)

The result it immediate ```````````````````````

Run it:

.. code:: bash

$ python hello_sphinx.py

hello_sphinx.py:23: DeprecationWarning: Call to deprecated function (or staticmethod) function_three.
(This function will be removed soon) -- Deprecated since version 1.0.
  function_three()  # warns

Help on function function_one in module __main__:

function_one()
    This is the function one

    .. versionadded:: 1.0
       This function is new

Help on function function_two in module __main__:

function_two()
    This is the function two

    .. versionchanged:: 1.0
       This function is modified

Help on function function_three in module __main__:

function_three()
    This is the function three

    .. deprecated:: 1.0
       This function will be removed soon
