 EIN -- Emacs IPython Notebook |build-status| |melpa-dev| |melpa-stable|
========================================================================

  --- or **E**\ IN **I**\ s not only for **N**\ otebooks.

Emacs IPython Notebook (EIN) lets you edit and run Jupyter_ (formerly IPython) notebooks within Emacs.  It channels all the power of Emacs without the idiosyncrasies of in-browser editing.

EIN was originally written by tkf_.  More `complete documentation`_ is available.

Install
=======
Install from MELPA_ (recommended) or ``make install`` from github source.

Usage
=====
There are multiple, mutually exclusive ways to launch EIN.

Launch a local session
----------------------
``M-x ein:jupyter-server-start`` (aliased ``M-x ein:run``) launches a jupyter process from emacs.

Login to a local or remote session
----------------------------------
``M-x ein:notebooklist-login`` (aliased ``M-x ein:login``) to a running jupyter server.

Jupyter services relayed over HTTP such as ``mybinder.org`` require cookie authentication.  Issuing ``C-u M-x ein:login`` prompts for cookie information.  See the `Wiki`_ for more information.

Open a notebook file
--------------------
Open an ``.ipynb`` file normally in emacs and press ``C-c C-o``.

.. _MELPA: http://melpa.org/#/

It doesn't work
---------------
EIN is tested and developed on GNU Emacs.  Your mileage may vary with the `spacemacs layer`_ and other *emacsen*.

You may also try to self-diagnose:

First invoke ``M-x ein:dev-start-debug``.  Then reproduce the error.

Higher level diagnostics appear in ``M-x ein:log-pop-to-all-buffer``.

Lower level diagnostics (the actual ``curl`` requests) appear in ``M-x ein:log-pop-to-request-buffer``.

If you cannot resolve the problem, file an issue using ``M-x ein:dev-bug-report-template``.  Please ensure the resulting system output does not include information sensitive to your institution.

Highlighted Features
====================

* Easily copy cells between different notebooks.
* Execute code from an arbitrary buffer in a running kernel.  See `Keybindings - Connect`_.
* Jump to definition via ``M-.``
* Completion via company-mode_.
* Limited jupyterhub_ support.

Org-mode Integration
====================

EIN provides org-babel functionality similar to ob-ipython_ and scimax_.  Acknowledgements to those fine packages.

*Language* is ``ein``.  The ``:session`` header argument is the notebook url, e.g., ``https://localhost:8888/my.ipynb``, or simply ``localhost``, in which case EIN will evaluate org blocks in an anonymous notebook::

   #BEGIN_SRC ein :session localhost :results raw drawer :image output.png
   import matplotlib.pyplot as plt
   import numpy as np

   %matplotlib inline
   x = np.linspace(0, 1, 100)
   y = np.random.rand(100,1)
   plt.plot(x,y)
   #+END_SRC

You may also specify the port, i.e., ``localhost:8889``.  See `complete details`_.
