hottie

Code hot-swapping for Python 2.7 classes and functions.

v0.1.0

GOAL: Feel a little bit like Bret Victor.

NON-GOAL: Provide a general solution for hot-swapping everything in all edge-case scenarios.

Usage

Decorate classes and functions that you would like to hot-swap with @hot decorator:

from hottie import hot

@hot
class Rocket(object):
    '...'

Check out the demo.

Installation

pip install hottie

How it works

@hot functions are proxies to real functions and @hot instances are observers that get their .__class__ changed when their class is updated. This slightly decreases performance. If you want to take advantage of hot-swapping only in development, use @hot like this:

import hottie

if DEVELOPMENT:
    hot = hottie.hot
else:
    hot = hottie.identity
