Python-version-sensitive monkeypatching.

ook is a simple library to assist with monkeypatching Python methods and
functions on a per-Python-version basis. It provides one decorator, patch,
which conditionally patches callables depending on which version of Python is
running.
Adding the compress() function to Python 2.6's itertools module:
import itertools
from ook import patch
# http://docs.python.org/2.7/library/itertools.html#itertools.compress
@patch(itertools, 2.6)
def compress(data, selectors):
# compress('ABCDEF', [1,0,1,0,1,1]) --> A C E F
return (d for d, s in itertools.izip(data, selectors) if s)
patch accepts an arbitrary number of version arguments, in a variety of
formats:
@patch(some.module.or.class, 2.7, "2.6.8", (3, 2, 5), 3)
def method_or_function(signature):
"""Do something."""
pass
... as well as min and max keyword arguments:
@patch(some.module.or.class, min="2.6.5", max=2.7)
def method_or_function(signature):
"""Do something."""
pass
... which can be combined:
@patch(some.module.or.class, "3.2.5", max=3.2)
def method_or_function(signature):
"""Do something."""
pass
Note: If you specify both keyword and non-keyword version arguments, the patch will only take effect if both the explicitly specified versions and the implied version ranges are satisfied.
With no arguments other than the module or class to be patched, patch
applies the patch regardless of Python version:
@patch(some.module.or.class)
def method_or_function(signature):
"""Do something, no matter what."""
pass
This should do the trick:
pip install ook
ook was (cough) "inspired" by Guido van Rossum's monkeypatch recipe. Thanks, Guido :-)
