             Make sure you have backup!

Features
========

* Copy/paste cells, even to/from different notebooks.
* Console integration: You can easily connect to kernel via console
  application.  This enables you to start debugging in the same
  kernel.

These features are currently not in the native IPython notebook, so
use Emacs IPython Notebook client (EIN) if you want them!  Of course,
EIN does not (and won't) implement rich object representation as
native IPython Notebook web client, and you should use browser also to
get full power of IPython Notebook.  EIN aims at making notebook
*editing* more effective.

Other features:

* Inline images
* Syntax highlighting in each cell types (Python/Markdown)
* Help browser (opens when executing ``function?``)

More to come/ideas:

* Auto-completion using `auto-complete.el`_
* Popup help
* Better pager (history, syntax highlighting, ...)
* Better messages/event handling/UI
* Auto-save
* Local auto-backup
* VCS integration

.. _auto-complete.el: http://cx4a.org/software/auto-complete/


Requirements
============

* IPython_ **0.12.1**: EIN won't work with older versions.
* `websocket.el`_
* (optional) mumamo_:
  It will be automatically loaded when it is on the path.
  The official way to setup path is to load nXhtml_.
* (optional) markdown-mode
* (optional) python-mode:
  It should work with either python.el or python-mode.el.
  Fabian Gallina's `python.el`_ is required to use
  ``ein:notebook-console-open`` command.
* (optional) `smartrep.el`_:
  This package enables you to omit typing prefix keys (e.g.,
  ``C-c C-n C-n C-n ...`` instead of ``C-c C-n C-c C-n C-c C-n ...``).
  You need to require subpackage (``(require 'ein-smartrep)``) to enable
  this feature.

Also, EIN heavily relies on standard Emacs libraries including EWOC
and EIEIO.  EIN is currently tested in Emacs 24.1.

1. Install module.
   Put Emacs lisp ``ein*.el`` files in your load path.

2. Require module::

     (require 'ein)

3. Start `IPython notebook server`_.

4. Hit ``M-x ein:notebooklist-open`` to open notebook list.
