Easily eats exceptions using decorators
Project description
Python library for easily “eating” exceptions in functions. Eating can mean either returning a default value or calling another function.
Introduction
This library is basically just a function, namely hungry.eat. Initially, I wrote it for a document parser in which there was a lot of exception handling logic for stuff I didn’t really care particularly much about.
Example usage
Eat ValueError exceptions and return 0.
@hungry.eat(ValueError, error_value=0)
Eat IndexError and ValueError and fall back to function get_first_element on errors.
@hungry.eat(IndexError, ValueError, error_handler=get_first_element)
In the example above, get_first_element will be passed the exception as the first argument, followed by all the other arguments and keyword arguments in the decorated function. This means that get_first_element would have e.g. the following signature:
def get_first_element(exception, *args, **kwargs):
Running tests
The tests use pytest. To run the tests without installing anything, execute:
$ python runtests.py
TODO
Complete the test suite.
