%global _empty_manifest_terminate_build 0
Name: python-biwrap
Version: 0.1.6
Release: 1
Summary: Yet simple util to make wrapper with optional arguments
License: MIT License
URL: https://github.com/ferrine/biwrap
Source0: https://mirrors.aliyun.com/pypi/web/packages/ac/54/78d4d5459d7385f90908185641647ff2e8ed4a4b5c239976f78e26888679/biwrap-0.1.6.tar.gz
BuildArch: noarch
%description
The above example shows redundancy in
- decorator definition has double nesting (double ``def``)
- usage requires trailing parenthesis ``@register()`` even in case we do not use optional argument
More readable code should avoid these two points and look like:
def register(fn, alias=None):
@register
def f1(a):
return a
@register(alias='fn3') # <- (1)
def f2(a):
return a
Naive implementation of the above API won't work. Line marked above as ``(1)`` will fail as first argument ``fn`` is not passed. But we want the output to be the same.
Better solution
***************
import biwrap
@biwrap.biwrap
def register(fn, alias=None):
if fn.__name__ not in register.storage:
register.storage[fn.__name__] = fn
elif register.storage[fn.__name__] is not fn:
raise KeyError('{} is already in storage'.format(fn.__name__))
if alias is not None and alias not in register.storage:
register.storage[alias] = fn
elif alias is not None:
raise KeyError('{} is already in storage'.format(alias))
return fn
register.storage = {}
@register
def f1(a):
return a
print(register.storage)
#> {'f1': <function f1 at 0x10f45a048>}

Functionality Overview
######################
Some corner cases may exist and custom coding can create a boilerplate for each usecase (see this `SO thread <https://stackoverflow.com/questions/3888158/making-decorators-with-optional-arguments>`__). This package takes the best and implements yet simple but generic solution to resolve them all(?).
Setup
*****
Let's take a simple wrapper as an example. It will print ``hi`` or ``bye`` depending on parametrization, default is ``hi``.
import biwrap
@biwrap.biwrap
def hiwrap(fn, hi=True):
def new(*args, **kwargs):
if hi:
print('hi')
else:
print('bye')
return fn(*args, **kwargs)
return new
