 """Hooks for IPython.
 
 In Python, it is possible to overwrite any method of any object if you really
 want to.  But IPython exposes a few 'hooks', methods which are *designed* to
 be overwritten by users for customization purposes.  This module defines the
 default versions of all such hooks, which get used by IPython if not
 overridden by the user.
 
 Hooks are simple functions, but they should be declared with ``self`` as their
 first argument, because when activated they are registered into IPython as
 instance methods. The self argument will be the IPython running instance
 itself, so hooks have full access to the entire IPython object.
 
 If you wish to define a new hook and activate it, you can make an :doc:`extension
 </config/extensions/index>` or a :ref:`startup script <startup_files>`. For
 example, you could use a startup file like this::
 
     import os
 
     def calljed(self,filename, linenum):
         "My editor hook calls the jed editor directly."
         print "Calling my own editor, jed ..."
         if os.system('jed +%d %s' % (linenum,filename)) != 0:
             raise TryNext()
 
     def load_ipython_extension(ip):
         ip.set_hook('editor', calljed)

 """
 IPython provides a rich toolkit to help you make the most out of using Python
 interactively.  Its main components are:
 
 * A powerful interactive Python shell
 * A `Jupyter <http://jupyter.org/>`_ kernel to work with Python code in Jupyter
   notebooks and other interactive frontends.
 
 The enhanced interactive Python shells have the following main features:
 
 * Comprehensive object introspection.
 
 * Input history, persistent across sessions.
 
 * Caching of output results during a session with automatically generated
   references.
 
 * Extensible tab completion, with support by default for completion of python
   variables and keywords, filenames and function keywords.
 
 * Extensible system of 'magic' commands for controlling the environment and
   performing many tasks related either to IPython or the operating system.
 
 * A rich configuration system with easy switching between different setups
   (simpler than changing $PYTHONSTARTUP environment variables every time).
 
 * Session logging and reloading.
 
 * Extensible syntax processing for special purpose situations.
 
 * Access to the system shell with user-extensible alias system.
 
 * Easily embeddable in other Python programs and GUIs.
 
 * Integrated access to the pdb debugger and the Python profiler.
 
 The latest development version is always available from IPython's `GitHub
 site <http://github.com/ipython>`_.
