.. funcsigs documentation master file, created by
sphinx-quickstart on Fri Apr 20 20:27:52 2012.
You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.
Introducing funcsigs
====================
The Funcsigs Package
--------------------
``funcsigs`` is a backport of the `PEP 362`_ function signature features from
Python 3.3's `inspect`_ module. The backport is compatible with Python 2.6, 2.7
as well as 3.3 and up. 3.2 was supported by version 0.4, but with setuptools and
pip no longer supporting 3.2, we cannot make any statement about 3.2
compatibility.
Compatibility
`````````````
The ``funcsigs`` backport has been tested against:
* CPython 2.6
* CPython 2.7
* CPython 3.3
* CPython 3.4
* CPython 3.5
* CPython nightlies
* PyPy and PyPy3(currently failing CI)
Continuous integration testing is provided by `Travis CI`_.
Under Python 2.x there is a compatibility issue when a function is assigned to
the ``__wrapped__`` property of a class after it has been constructed.
Similiarily there under PyPy directly passing the ``__call__`` method of a
builtin is also a compatibility issues. Otherwise the functionality is
believed to be uniform between both Python2 and Python3.
Issues
``````
Source code for ``funcsigs`` is hosted on `GitHub`_. Any bug reports or feature
requests can be made using GitHub's `issues system`_. |build_status| |coverage|
Example
-------
To obtain a `Signature` object, pass the target function to the
``funcsigs.signature`` function.
.. code-block:: python
>>> from funcsigs import signature
>>> def foo(a, b=None, *args, **kwargs):
... pass
...
>>> sig = signature(foo)
>>> sig
<funcsigs.Signature object at 0x...>
>>> sig.parameters
OrderedDict([('a', <Parameter at 0x... 'a'>), ('b', <Parameter at 0x... 'b'>), ('args', <Parameter at 0x... 'args'>), ('kwargs', <Parameter at 0x... 'kwargs'>)])
>>> sig.return_annotation
<class 'funcsigs._empty'>
Introspecting callables with the Signature object
-------------------------------------------------
.. note::
This section of documentation is a direct reproduction of the Python
standard library documentation for the inspect module.
The Signature object represents the call signature of a callable object and its
return annotation. To retrieve a Signature object, use the :func:`signature`
function.
.. function:: signature(callable)
Return a :class:`Signature` object for the given ``callable``::
>>> from funcsigs import signature
>>> def foo(a, *, b:int, **kwargs):
... pass
>>> sig = signature(foo)
>>> str(sig)
'(a, *, b:int, **kwargs)'
>>> str(sig.parameters['b'])
'b:int'
>>> sig.parameters['b'].annotation
<class 'int'>
Accepts a wide range of python callables, from plain functions and classes to
:func:`functools.partial` objects.
.. note::
Some callables may not be introspectable in certain implementations of
Python. For example, in CPython, built-in functions defined in C provide
no metadata about their arguments.
.. class:: Signature
A Signature object represents the call signature of a function and its return
annotation. For each parameter accepted by the function it stores a
:class:`Parameter` object in its :attr:`parameters` collection.
Signature objects are *immutable*. Use :meth:`Signature.replace` to make a
modified copy.
.. attribute:: Signature.empty
A special class-level marker to specify absence of a return annotation.
.. attribute:: Signature.parameters
An ordered mapping of parameters' names to the corresponding
:class:`Parameter` objects.
.. attribute:: Signature.return_annotation
The "return" annotation for the callable. If the callable has no "return"
annotation, this attribute is set to :attr:`Signature.empty`.
.. method:: Signature.bind(*args, **kwargs)
Create a mapping from positional and keyword arguments to parameters.
Returns :class:`BoundArguments` if ``*args`` and ``**kwargs`` match the
signature, or raises a :exc:`TypeError`.
.. method:: Signature.bind_partial(*args, **kwargs)
Works the same way as :meth:`Signature.bind`, but allows the omission of
some required arguments (mimics :func:`functools.partial` behavior.)
Returns :class:`BoundArguments`, or raises a :exc:`TypeError` if the
passed arguments do not match the signature.
.. method:: Signature.replace(*[, parameters][, return_annotation])
Create a new Signature instance based on the instance replace was invoked
on. It is possible to pass different ``parameters`` and/or
``return_annotation`` to override the corresponding properties of the base
signature. To remove return_annotation from the copied Signature, pass in
:attr:`Signature.empty`.
::
>>> def test(a, b):
... pass
>>> sig = signature(test)
>>> new_sig = sig.replace(return_annotation="new return anno")
>>> str(new_sig)
"(a, b) -> 'new return anno'"
.. class:: Parameter
Parameter objects are *immutable*. Instead of modifying a Parameter object,
you can use :meth:`Parameter.replace` to create a modified copy.
.. attribute:: Parameter.empty
A special class-level marker to specify absence of default values and
annotations.
.. attribute:: Parameter.name
The name of the parameter as a string. Must be a valid python identifier
name (with the exception of ``POSITIONAL_ONLY`` parameters, which can have
it set to ``None``).
.. attribute:: Parameter.default
The default value for the parameter. If the parameter has no default
value, this attribute is set to :attr:`Parameter.empty`.
.. attribute:: Parameter.annotation
The annotation for the parameter. If the parameter has no annotation,
this attribute is set to :attr:`Parameter.empty`.
.. attribute:: Parameter.kind
Describes how argument values are bound to the parameter. Possible values
(accessible via :class:`Parameter`, like ``Parameter.KEYWORD_ONLY``):
+------------------------+----------------------------------------------+
| Name | Meaning |
+========================+==============================================+
| *POSITIONAL_ONLY* | Value must be supplied as a positional |
| | argument. |
| | |
| | Python has no explicit syntax for defining |
| | positional-only parameters, but many built-in|
| | and extension module functions (especially |
| | those that accept only one or two parameters)|
| | accept them. |
+------------------------+----------------------------------------------+
| *POSITIONAL_OR_KEYWORD*| Value may be supplied as either a keyword or |
| | positional argument (this is the standard |
| | binding behaviour for functions implemented |
| | in Python.) |
+------------------------+----------------------------------------------+
| *VAR_POSITIONAL* | A tuple of positional arguments that aren't |
| | bound to any other parameter. This |
| | corresponds to a ``*args`` parameter in a |
| | Python function definition. |
+------------------------+----------------------------------------------+
| *KEYWORD_ONLY* | Value must be supplied as a keyword argument.|
| | Keyword only parameters are those which |
| | appear after a ``*`` or ``*args`` entry in a |
| | Python function definition. |
+------------------------+----------------------------------------------+
| *VAR_KEYWORD* | A dict of keyword arguments that aren't bound|
| | to any other parameter. This corresponds to a|
| | ``**kwargs`` parameter in a Python function |
| | definition. |
+------------------------+----------------------------------------------+
Example: print all keyword-only arguments without default values::
>>> def foo(a, b, *, c, d=10):
... pass
>>> sig = signature(foo)
>>> for param in sig.parameters.values():
... if (param.kind == param.KEYWORD_ONLY and
... param.default is param.empty):
... print('Parameter:', param)
Parameter: c
.. method:: Parameter.replace(*[, name][, kind][, default][, annotation])
Create a new Parameter instance based on the instance replaced was invoked
on. To override a :class:`Parameter` attribute, pass the corresponding
argument. To remove a default value or/and an annotation from a
Parameter, pass :attr:`Parameter.empty`.
::
>>> from funcsigs import Parameter
>>> param = Parameter('foo', Parameter.KEYWORD_ONLY, default=42)
>>> str(param)
'foo=42'
>>> str(param.replace()) # Will create a shallow copy of 'param'
'foo=42'
>>> str(param.replace(default=Parameter.empty, annotation='spam'))
"foo:'spam'"
.. class:: BoundArguments
Result of a :meth:`Signature.bind` or :meth:`Signature.bind_partial` call.
Holds the mapping of arguments to the function's parameters.
.. attribute:: BoundArguments.arguments
An ordered, mutable mapping (:class:`collections.OrderedDict`) of
parameters' names to arguments' values. Contains only explicitly bound
arguments. Changes in :attr:`arguments` will reflect in :attr:`args` and
:attr:`kwargs`.
Should be used in conjunction with :attr:`Signature.parameters` for any
argument processing purposes.
.. note::
Arguments for which :meth:`Signature.bind` or
:meth:`Signature.bind_partial` relied on a default value are skipped.
However, if needed, it is easy to include them.
::
>>> def foo(a, b=10):
... pass
>>> sig = signature(foo)
>>> ba = sig.bind(5)
>>> ba.args, ba.kwargs
((5,), {})
>>> for param in sig.parameters.values():
... if param.name not in ba.arguments:
... ba.arguments[param.name] = param.default
>>> ba.args, ba.kwargs
((5, 10), {})
.. attribute:: BoundArguments.args
A tuple of positional arguments values. Dynamically computed from the
:attr:`arguments` attribute.
.. attribute:: BoundArguments.kwargs
A dict of keyword arguments values. Dynamically computed from the
:attr:`arguments` attribute.
The :attr:`args` and :attr:`kwargs` properties can be used to invoke
functions::
def test(a, *, b):
...
sig = signature(test)
ba = sig.bind(10, b=20)
test(*ba.args, **ba.kwargs)
