Python Exception Based Callbacks

Project description

Python Exception Based Callbacks

https://travis-ci.org/TheSriram/smoothie.svg?branch=master

Add your callbacks to functions as decorators, that are slated to be called as per the Exception raised.

from smoothie.king import Dispenser

def err_callback(*args, **kwargs):
    print("Error handled")

juice = Dispenser()

@juice.attach(exception=IndexError,
              callback=err_callback)
def vending_machine():
    drinks = ['Tea','Coffee', 'Water']
    return drinks[4]

vending_machine()

To run the unit tests,

pip install -r test-requirements.txt
cd smoothie/tests  nosetests -vs``
