bluesky.run_engine.Dispatcher.subscribe

Dispatcher.subscribe(func, name='all')

Register a callback function to consume documents.

Changed in version 0.10.0: The order of the arguments was swapped and the name argument has been given a default value, 'all'. Because the meaning of the arguments is unambiguous (they must be a callable and a string, respectively) the old order will be supported indefinitely, with a warning.
