<pre class="literalblock">
A decorator to declare that only the first N arguments my be positional.
This decorator makes it easy to support Python 3 style keyword-only
parameters. For example, in Python 3 it is possible to write::
def fn(pos1, *, kwonly1=None, kwonly1=None):
...
All named parameters after ``*`` must be a keyword::
fn(10, 'kw1', 'kw2') # Raises exception.
fn(10, kwonly1='kw1') # Ok.
Example
^^^^^^^
To define a function like above, do::
@positional(1)
def fn(pos1, kwonly1=None, kwonly2=None):
...
If no default value is provided to a keyword argument, it becomes a
required keyword argument::
@positional(0)
def fn(required_kw):
...
This must be called with the keyword parameter::
fn() # Raises exception.
fn(10) # Raises exception.
fn(required_kw=10) # Ok.
When defining instance or class methods always remember to account for
``self`` and ``cls``::
class MyClass(object):
@positional(2)
def my_method(self, pos1, kwonly1=None):
...
@classmethod
@positional(2)
def my_method(cls, pos1, kwonly1=None):
...
The positional decorator behavior is controlled by
``_helpers.positional_parameters_enforcement``, which may be set to
``POSITIONAL_EXCEPTION``, ``POSITIONAL_WARNING`` or
``POSITIONAL_IGNORE`` to raise an exception, log a warning, or do
nothing, respectively, if a declaration is violated.
Args:
max_positional_arguments: Maximum number of positional arguments. All
parameters after the this index must be
keyword only.
Returns:
A decorator that prevents using arguments after max_positional_args
from being used as positional parameters.
Raises:
TypeError: if a key-word only argument is provided as a positional
parameter, but only if
_helpers.positional_parameters_enforcement is set to
POSITIONAL_EXCEPTION.
