Utility functions for monkey-patching python code

Project description

About

python-monkey-business is a package that provides a decorator for monkey-patching python functions at runtime.

Installation

Using pip:

pip install python-monkey-business

Or, to install from source:

pip install -e git+https://github.com/theatlantic/python-monkey-business.git#egg=python-monkey-business

If the source is already checked out, use setuptools:

python setup.py develop

Usage

To use python-monkey-business to swap out a function in a class or module at runtime:

import monkeybiz

from foomodule import FooClass
import barmodule


# This replaces FooClass.bar with our method
@monkeybiz.patch(FooClass)
def bar(original_fn, *args, **kwargs):
    print "Patched!"
    return original_fn(*args, **kwargs)

# This replaces barmodule.baz with our function
@monkeybiz.patch(barmodule)
def baz(original_fn, *args, **kwargs):
    #...

The first argument to monkeybiz.patch can be either a module, a class, or a list of modules and/or classes. The decorator also takes optional name and avoid_doublewrap keyword arguments. If name is omitted, the name of the function being patched will be the name of the function being decorated. If avoid_doublewrap is True (the default), then functions and methods can only be patched once using this function.

Use monkeybiz.unpatch() to revert a monkey-patched function to its original.
