Install
=======
Clone this repo and ``make install``.  You will need `Cask`_.

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.

Alternatively, ob-ein_.

**Please file issues using** ``M-x ein:dev-bug-report-template``.

You may also try to self-diagnose.

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

General logging ``M-x ein:log-pop-to-all-buffer``.

Configuration:

::

   M-x customize-group RET org-babel
   Org Babel Load Languages:
     Insert (ein . t)
     For example, '((emacs-lisp . t) (ein . t))

Snippet:

::

   #BEGIN_SRC ein-python :session localhost :results raw drawer
     import numpy, math, matplotlib.pyplot as plt
     %matplotlib inline
     x = numpy.linspace(0, 2*math.pi)
     plt.plot(x, numpy.sin(x))
   #+END_SRC

The ``:session`` is the notebook url, e.g., ``http://localhost:8888/my.ipynb``, or simply ``localhost``, in which case org evaluates anonymously.  A port may also be specified, e.g., ``localhost:8889``.

*Language* can be ``ein-python``, ``ein-r``, or ``ein-julia``.  **The relevant** `jupyter kernel`_ **must be installed before use**.  Additional languages can be configured via::

   M-x customize-group RET ein
