A tool to keep Mac OS X from sleeping

Project description

Use this module to prevent your Mac OS X system from sleeping while executing a long-running python script.

Quick Start

Just import caffeine. That’s it! You Mac OS X system will not sleep as long as the interpreter remains alive. No need to run any other commands. But if you want slightly finer controls, a few functions are available.

caffeine.on(display=False)

Use the on function to create a power assertion. Set display=True to also keep your display from sleeping. The default of display=False will allow your display to sleep but will keep your system awake so processing can continue. If a power assertion is active, calling on() with display set to the other value will change the assertion. Calling on() with the same value is a harmless no-op.

caffeine.off()

Use the off function to release any power assertion before your interpreter exits.

caffeine.verify()

Calls pmset -g assertions to verify what power assertions are active.
