jdZddlmZGddeZiZdZedZedZedZ ed Z ed Z d S) aoInfrastructure for registering and firing callbacks on application events. Unlike :mod:`IPython.core.hooks`, which lets end users set single functions to be called at specific times, or a collection of alternative methods to try, callbacks are designed to be used by extension authors. A number of callbacks can be registered for the same event without needing to be aware of one another. The functions defined in this module are no-ops indicating the names of available events and the arguments which will be passed to them. .. note:: This API is experimental in IPython 2.0, and may be revised in future versions. )callback_prototypec*eZdZdZdZdZdZdZdS) EventManagera3Manage a collection of events and a sequence of callbacks for each. This is attached to :class:`~IPython.core.interactiveshell.InteractiveShell` instances as an ``events`` attribute. .. note:: This API is experimental in IPython 2.0, and may be revised in future versions. c6||_d|D|_dS)aInitialise the :class:`CallbackManager`.
