Decorum 0.3

Tool for writing simple decorators

Decorum is a simple tool which aims to make it easier to write flexible and simple decorators. It can also act similarly to functools.wraps.

Typical usage looks like this:

from decorum import decorator

class my_decorator(decorator):

def wraps(self, f):

print “I’m returning the function! You can keep it!” return f

Decorum makes lets you write decorators in a unified way. Your decorator can be used with or without arguments, and it will work the same way.

@my_decorator def foo(x): print x

Is identical to:

@my_decorator() def foo(x): print x

Writing decorators

There are two many methods you’ll want to use in your subclassed decorators. Customize wraps to handle the decoration, and return (or not) the wrapped function, and use init to handle any optional arguments.
