+Version: 1.12.1
+Summary: Module for decorators, wrappers and monkey patching.

+Description: wrapt
+ =====
+
+ |Travis| |AppVeyor| |Coveralls| |PyPI|
+
+ The aim of the **wrapt** module is to provide a transparent object proxy
+ for Python, which can be used as the basis for the construction of function
+ wrappers and decorator functions.
+
+ The **wrapt** module focuses very much on correctness. It therefore goes
+ way beyond existing mechanisms such as ``functools.wraps()`` to ensure that
+ decorators preserve introspectability, signatures, type checking abilities
+ etc. The decorators that can be constructed using this module will work in
+ far more scenarios than typical decorators and provide more predictable and
+ consistent behaviour.
+
+ To ensure that the overhead is as minimal as possible, a C extension module
+ is used for performance critical components. An automatic fallback to a
+ pure Python implementation is also provided where a target system does not
+ have a compiler to allow the C extension to be compiled.
+
+ Documentation
+ -------------
+
+ For further information on the **wrapt** module see:
+
+ * http://wrapt.readthedocs.org/
+
+ Quick Start
+ -----------
+
+ To implement your decorator you need to first define a wrapper function.
+ This will be called each time a decorated function is called. The wrapper
+ function needs to take four positional arguments:
+
+ * ``wrapped`` - The wrapped function which in turns needs to be called by your wrapper function.
+ * ``instance`` - The object to which the wrapped function was bound when it was called.
+ * ``args`` - The list of positional arguments supplied when the decorated function was called.
+ * ``kwargs`` - The dictionary of keyword arguments supplied when the decorated function was called.
+
+ The wrapper function would do whatever it needs to, but would usually in
+ turn call the wrapped function that is passed in via the ``wrapped``
+ argument.
+
+ The decorator ``@wrapt.decorator`` then needs to be applied to the wrapper
+ function to convert it into a decorator which can in turn be applied to
+ other functions.
+
+ ::
+
+ import wrapt
+
+ @wrapt.decorator
+ def pass_through(wrapped, instance, args, kwargs):
+ return wrapped(*args, **kwargs)
+
+ @pass_through
+ def function():
+ pass
+
+ If you wish to implement a decorator which accepts arguments, then wrap the
+ definition of the decorator in a function closure. Any arguments supplied
+ to the outer function when the decorator is applied, will be available to
+ the inner wrapper when the wrapped function is called.
+
+ ::
+
+ import wrapt
+
+ def with_arguments(myarg1, myarg2):
+ @wrapt.decorator
+ def wrapper(wrapped, instance, args, kwargs):
+ return wrapped(*args, **kwargs)
+ return wrapper
+
+ @with_arguments(1, 2)
+ def function():
+ pass
+
+ When applied to a normal function or static method, the wrapper function
+ when called will be passed ``None`` as the ``instance`` argument.
+
+ When applied to an instance method, the wrapper function when called will
+ be passed the instance of the class the method is being called on as the
+ ``instance`` argument. This will be the case even when the instance method
+ was called explicitly via the class and the instance passed as the first
+ argument. That is, the instance will never be passed as part of ``args``.
+
+ When applied to a class method, the wrapper function when called will be
+ passed the class type as the ``instance`` argument.
+
+ When applied to a class, the wrapper function when called will be passed
+ ``None`` as the ``instance`` argument. The ``wrapped`` argument in this
+ case will be the class.
+
+ The above rules can be summarised with the following example.
+
+ ::
+
+ import inspect
+
+ @wrapt.decorator
+ def universal(wrapped, instance, args, kwargs):
+ if instance is None:
+ if inspect.isclass(wrapped):
+ # Decorator was applied to a class.
+ return wrapped(*args, **kwargs)
+ else:
+ # Decorator was applied to a function or staticmethod.
+ return wrapped(*args, **kwargs)
+ else:
+ if inspect.isclass(instance):
+ # Decorator was applied to a classmethod.
+ return wrapped(*args, **kwargs)
+ else:
+ # Decorator was applied to an instancemethod.
+ return wrapped(*args, **kwargs)
+
+ Using these checks it is therefore possible to create a universal decorator
+ that can be applied in all situations. It is no longer necessary to create
+ different variants of decorators for normal functions and instance methods,
+ or use additional wrappers to convert a function decorator into one that
+ will work for instance methods.
+
+ In all cases, the wrapped function passed to the wrapper function is called
+ in the same way, with ``args`` and ``kwargs`` being passed. The
+ ``instance`` argument doesn't need to be used in calling the wrapped
+ function.
+

+ # class. Further, we need to know when it is likely an instance
+ # method, as opposed to a class or static method. This can
+ # become problematic though as there isn't strictly a fool proof
+ # method of knowing.
+ #
+ # The situations we could encounter when wrapping a method are:
+ #
+ # 1. The wrapper is being applied as part of a decorator which
+ # is a part of the class definition. In this case what we are
+ # given is the raw unbound function, classmethod or staticmethod
+ # wrapper objects.
+ #
+ # The problem here is that we will not know we are being applied
+ # in the context of the class being set up. This becomes
+ # important later for the case of an instance method, because in
+ # that case we just see it as a raw function and can't
+ # distinguish it from wrapping a normal function outside of
+ # a class context.
+ #
+ # 2. The wrapper is being applied when performing monkey
+ # patching of the class type afterwards and the method to be
+ # wrapped was retrieved direct from the __dict__ of the class
+ # type. This is effectively the same as (1) above.
+ #
+ # 3. The wrapper is being applied when performing monkey
+ # patching of the class type afterwards and the method to be
+ # wrapped was retrieved from the class type. In this case
+ # binding will have been performed where the instance against
+ # which the method is bound will be None at that point.
+ #
+ # This case is a problem because we can no longer tell if the
+ # method was a static method, plus if using Python3, we cannot
+ # tell if it was an instance method as the concept of an
+ # unnbound method no longer exists.
+ #
+ # 4. The wrapper is being applied when performing monkey
+ # patching of an instance of a class. In this case binding will
+ # have been perfomed where the instance was not None.
+ #
+ # This case is a problem because we can no longer tell if the
+ # method was a static method.
+ #
+ # Overall, the best we can do is look at the original type of the
+ # object which was wrapped prior to any binding being done and
+ # see if it is an instance of classmethod or staticmethod. In
+ # the case where other decorators are between us and them, if
+ # they do not propagate the __class__ attribute so that the
+ # isinstance() checks works, then likely this will do the wrong
+ # thing where classmethod and staticmethod are used.
+ #
+ # Since it is likely to be very rare that anyone even puts
+ # decorators around classmethod and staticmethod, likelihood of
+ # that being an issue is very small, so we accept it and suggest
+ # that those other decorators be fixed. It is also only an issue
+ # if a decorator wants to actually do things with the arguments.
+ #
+ # As to not being able to identify static methods properly, we
+ # just hope that that isn't something people are going to want
+ # to wrap, or if they do suggest they do it the correct way by
+ # ensuring that it is decorated in the class definition itself,
+ # or patch it in the __dict__ of the class type.
+ #
+ # So to get the best outcome we can, whenever we aren't sure what

+
+Introduction
+------------
+
+Url is constructed from ``str``:
+
+.. code-block:: pycon
+
+ >>> from yarl import URL
+ >>> url = URL('https://www.python.org/~guido?arg=1#frag')
+ >>> url
+ URL('https://www.python.org/~guido?arg=1#frag')
+
+All url parts: *scheme*, *user*, *password*, *host*, *port*, *path*,
+*query* and *fragment* are accessible by properties:
+
+.. code-block:: pycon
+
+ >>> url.scheme
+ 'https'
+ >>> url.host
+ 'www.python.org'
+ >>> url.path
+ '/~guido'
+ >>> url.query_string
+ 'arg=1'
+ >>> url.query
+ <MultiDictProxy('arg': '1')>
+ >>> url.fragment
+ 'frag'
+
+All url manipulations produce a new url object:
+
+.. code-block:: pycon
+
+ >>> url = URL('https://www.python.org')
+ >>> url / 'foo' / 'bar'
+ URL('https://www.python.org/foo/bar')
+ >>> url / 'foo' % {'bar': 'baz'}
+ URL('https://www.python.org/foo?bar=baz')
+
+Strings passed to constructor and modification methods are
+automatically encoded giving canonical representation as result:
+
+.. code-block:: pycon
+
+ >>> url = URL('https://www.python.org/путь')
+ >>> url
+ URL('https://www.python.org/%D0%BF%D1%83%D1%82%D1%8C')
+
+Regular properties are *percent-decoded*, use ``raw_`` versions for
+getting *encoded* strings:
+
+.. code-block:: pycon
+
+ >>> url.path
+ '/путь'
+
+ >>> url.raw_path
+ '/%D0%BF%D1%83%D1%82%D1%8C'
+
+Human readable representation of URL is available as ``.human_repr()``:
+
+.. code-block:: pycon
+
+ >>> url.human_repr()
+ 'https://www.python.org/путь'
+
+For full documentation please read https://yarl.readthedocs.org.
+
+
+Installation
+------------
+
+::
+
+ $ pip install yarl
+
+The library is Python 3 only!
+
+PyPI contains binary wheels for Linux, Windows and MacOS. If you want to install
+``yarl`` on another operating system (like *Alpine Linux*, which is not
+manylinux-compliant because of the missing glibc and therefore, cannot be
+used with our wheels) the the tarball will be used to compile the library from
+the source code. It requires a C compiler and and Python headers installed.
+
+To skip the compilation you must explicitly opt-in by setting the `YARL_NO_EXTENSIONS`
+environment variable to a non-empty value, e.g.:
+
+.. code-block:: bash
+
+ $ YARL_NO_EXTENSIONS=1 pip install yarl
+
+Please note that the pure-Python (uncompiled) version is much slower. However,
+PyPy always uses a pure-Python implementation, and, as such, it is unaffected
+by this variable.
+
+Dependencies
+------------
+
+YARL requires multidict_ library.
+
+
+API documentation
+------------------
+
+The documentation is located at https://yarl.readthedocs.org
+
+
+Why isn't boolean supported by the URL query API?
+-------------------------------------------------
+
+There is no standard for boolean representation of boolean values.
+
+Some systems prefer ``true``/``false``, others like ``yes``/``no``, ``on``/``off``,
+``Y``/``N``, ``1``/``0``, etc.
+
+``yarl`` cannot make an unambiguous decision on how to serialize ``bool`` values because
+it is specific to how the end-user's application is built and would be different for
+different apps. The library doesn't accept booleans in the API; a user should convert
+bools into strings using own preferred translation protocol.
+
+
+Comparison with other URL libraries
+------------------------------------
+
+* furl (https://pypi.python.org/pypi/furl)
+
+ The library has rich functionality but the ``furl`` object is mutable.
+
+ I'm afraid to pass this object into foreign code: who knows if the
+ code will modify my url in a terrible way while I just want to send URL
+ with handy helpers for accessing URL properties.
+
+ ``furl`` has other non-obvious tricky things but the main objection
+ is mutability.
+
+* URLObject (https://pypi.python.org/pypi/URLObject)
+
+ URLObject is immutable, that's pretty good.
+
+ Every URL change generates a new URL object.
+
+ But the library doesn't do any decode/encode transformations leaving the
+ end user to cope with these gory details.
+
+
+Source code

+The project is hosted on GitHub_
+
+Please file an issue on the `bug tracker
+<https://github.com/aio-libs/yarl/issues>`_ if you have found a bug
+or have some suggestion in order to improve the library.
+
+The library uses `Azure Pipelines <https://dev.azure.com/aio-libs/yarl>`_ for
+Continuous Integration.

+ `#435 <https://github.com/aio-libs/yarl/issues/435>`_
+- Allow use of sequences such as ``list`` and ``tuple`` in the values
+ of a mapping such as ``dict`` to represent that a key has many values::
+
+ url = URL("http://example.com")
+ assert url.with_query({"a": [1, 2]}) == URL("http://example.com/?a=1&a=2")
+
+ `#443 <https://github.com/aio-libs/yarl/issues/443>`_
