# Forbidden Fruit

![Forbidden Fruit](logo.png)

This project aims to give you the way to find heaven in tests, but it might lead you to hell if you use it on production code.

It basically allows you to patch built-in objects, declared in C through python. Just like this:

`python >>> from forbiddenfruit import curse >>> def words_of_wisdom(self): ...     return self * "blah " >>> curse(int, "words_of_wisdom", words_of_wisdom) >>> assert (2).words_of_wisdom() == "blah blah " `

Boom! That's it, your int class now has the words_of_wisdom method. Do you want to add a classmethod to a built-in class? No problem, just do this:

`python >>> from forbiddenfruit import curse >>> def hello(self): ...     return "blah" >>> curse(str, "hello", classmethod(hello)) >>> assert str.hello() == "blah" `

### Reversing a curse

If you want to free your object from a curse, you can use the reverse() function. Just like this:

`python >>> from forbiddenfruit import curse, reverse >>> curse(str, "test", "blah") >>> assert 'test' in dir(str) >>> # Time to reverse the curse >>> reverse(str, "test") >>> assert 'test' not in dir(str) `

## Compatibility

Forbidden Fruit runs on all cpython versions I tested so far, which includes the versions 2.5, 2.6, 2.7, 3.2 and 3.3. Since it depends fundamentally on the C API to implement its basic feature, this library won't work on other python implementations such as Jython, pypi, etc.

I might add support for pypi in the future, but It's unlikely that I'll do it for Jython. But I could happily accept patches for them.
