 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
=====
Start EIN using ONE of the following:

- Open an ``.ipynb`` file normally in emacs and press ``C-c C-o``, or,
- ``M-x ein:run`` launches a jupyter process from emacs, or,
- ``M-x ein:login`` to a running jupyter server

Use ``C-u M-x ein:login`` for services such as ``mybinder.org`` requiring cookie authentication.

It doesn't work
---------------

EIN is tested on GNU Emacs versions
25.2
and later. 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.

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

Low level diagnostics 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``.

I want to use Elpy, ESS, LSP, etc.
==================================

Enable `polymode`_ via::

   M-x customize-group RET ein
   Toggle Ein:Polymode
  
Org-mode Integration
====================

EIN provides org-babel functionality similar to ob-ipython_ and scimax_.

*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 `ob-ein details`_.

Connected Buffers
=================

Use ``M-x ein:connect-to-notebook`` to submit code from an arbitrary buffer to a running jupyter kernel.  See `connected buffer details`_.
