EIN -- Emacs IPython Notebook |build-status| |melpa-dev| |melpa-stable|
========================================================================
--- or **E**\ IN **I**\ s not only for **N**\ otebooks.
EIN works with IPython 2.x_, 3.x_, and Jupyter_! Note that remote and password
protected logins are working with IPython 3.x, but have not been tested with
Jupyter.
.. note:: The code has been stable enough for my day to day work, but there are
no guarantees for the safety for your notebook data. Please make sure
that you back-up and back-up often!
.. note:: The code for testing EIN is horribly broken, but I regularly hand
check the code running against IPython's suite of sample
notebooks. It's a worse-is-better solution to problem requiring a
time-consuming solution.

Org-mode Integration
====================
EIN now integrates_ with org-mode! The code was heavily inspired by ob-ipython_
which is another project very much worth checking out. Find it on MELPA_.

Features
========
The Emacs IPython Notebook (EIN) provides a client for IPython v2.x and 3.x and
Jupyter notebooks via an integrated REPL (like SLIME_) in Emacs. EIN makes
notebook editing very powerful by allowing you to use Emacs features; it also
expose IPython features such as code evaluation, object inspection and code
completion to the Emacs side. These features can be accessed anywhere in Emacs
and improve Python code editing and reading in Emacs.
.. _SLIME: http://common-lisp.net/project/slime/
Highlighted features:
* Copy/paste cells, even to/from different notebooks.
* Console integration: You can easily connect to a kernel via the console
application. This enables you to start debugging in the same kernel. It is
even possible to connect to a console over ssh.
* An IPython kernel can be "connected" to any buffer. This enables you to
evaluate a buffer or buffer region using the same kernel as the notebook.
Notebook goodies such as tooltip help, help browser and code completion are
available in these buffers.
* Jump to definition (go to the definition by hitting ``M-.`` over an object).
Other notebook features:
* Inline images
* Auto/manual-completion
* Popup (tooltip) help
* Syntax highlighting in each cell type (Python/Markdown)
* Help browser (opens when executing ``function?``)
* Traceback viewer
* Integration with org-mode
* Support for debugging via %debug
* Multiple python kernels
* EXPERIMENTAL: Non-python kernels! R runs in EIN, see the screenshot above!

Quick try
=========
Install from MELPA_! Seriously, installing from MELPA is the easiest way to
ensure all of ein's dependencies are correctly installed. `zeroein.el` is from a
bygone era and does not quite work the way it used to. If you are determined,
and slightly masochistic, you can attempt the following::
git clone git://github.com/millejoh/emacs-ipython-notebook.git
cd emacs-ipython-notebook/
lisp/zeroein.el
This will launch a new Emacs instance.
You can use environment variable ``EMACS`` to control Emacs executable
to use.::
EMACS=emacs-snapshot lisp/zeroein.el
The above command requires /bin/sh. If the above command does not work
(e.g., you are using MS Windows), try the following command::
emacs -Q -l lisp/zeroein.el
Requirements
============
* IPython_ 2.0 or higher or current versions of Jupyter_
* Tornado_ 4.0.2 or higher.
* `websocket.el`_ 1.3
* `request.el`_ >= 0.2
* (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:console-open`` command.
* (optional) `auto-complete.el`_
You need to configure subpackage ``ein-ac`` to enable
this feature.
* (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 configure subpackage ``ein-smartrep`` to enable
this feature.
* (optional) `jedi.el`_:
Python auto-completion for emacs using `jedi`_. In your
emacs initialization file add
``(add-hook 'ein:connect-mode-hook 'ein:jedi-setup)``
Also, EIN heavily relies on standard Emacs libraries including EWOC,
EIEIO and json.el. EIN is currently known to work in Emacs 25.1 and development
version (26.0.x).

Usage
=====
1. Install from MELPA_.
For manual install, put Emacs lisp ``ein*.el`` files and Python file
``ein.py`` in your load path. See `online documentation`_ for more
information.
2. Start the `Jupyter notebook server`_.
3. (Optional) Newer versions of Jupyter have token authentication_ enabled by
default so you will need to call ``M-x ein:notebooklist-login`` and enter the
token as the password.
4. Execute ``M-x ein:notebooklist-open`` to open notebook list.

Subpackages
-----------
Enable `auto-complete.el`_::

;; Or, to enable "superpack" (a little bit hacky improvements):
;; (setq ein:use-auto-complete-superpack t)
Enable `smartrep.el`_::
(setq ein:use-smartrep t)
