Scell: Selectors for Humans

Scell is a MIT-licensed selector library, written in Python.

At the heart of event-driven platforms is the selector, the humble select.select function. Using it is very simple, but requires you to pass in lists of file handles again and again. Keeping track of these file handles are tricky. Let Scell handle it for you and focus on building an awesome library/server:

>>> selector = scell.Selector()
>>> monitor = selector.register(open('file.txt'), mode='r')
>>> monitor.callback = lambda: 1
>>> [event.callback() for event in selector.ready]
[1]

Scell allows implementors to effortlessly build libraries atop of the minimal abstraction provided, while also having good performance. The API is very small and works across many platforms, including Windows and OSX.
