* Description
This layer adds support for the package =emacs-ipython-notebook=.

Do not hesitate to check the original package README [[https://github.com/millejoh/emacs-ipython-notebook][here]]. Also the wiki has
lots of informative stuff.

* Features
- Keybindings available through transient-state or leader key
- Lazy-loading

* List of TODOS
This is a WIP, feel free to collaborate.

** TODO Maybe it'd be better if there was a state for this
** TODO Make more keybinding to =connect= to a python buffer
** TODO Deleting visual regions don't work, find out why

* Install
** Layer
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
add =ipython-notebook= to the existing =dotspacemacs-configuration-layers= list
in this file.

** Dependencies
Install IPython Notebook > 3
#+begin_src sh
  pip install ipython[notebook]
#+end_src

** What needs to be run
Have an IPython notebook running
#+begin_src sh
  ipython notebook
#+end_src

* Using the IPython notebook
** Open Notebook List
This layer is lazy loaded so the transient-state will only work after you summon the
command =ein:notebooklist-open= which is bound to ~SPC a i n~

** Key Bindings
The key bindings can be used through a transient state or the usual evil-leader.

*** Transient-state: =ipython-notebook=
Once you are in the ipython notebook you can activate the transient-state with
~SPC m .~

The following table lists the keys. Use them as listed in the transient-state or
prefix with ~SPC m~ to use with your evil-leader.

| Key     | Function                                  |

*** Normal mode
In normal mode the following key bindings are defined:

| Key     | Function                                 |
|---------+------------------------------------------|
| ~gj~    | ein:worksheet-goto-next-input            |

| ~C-RET~ | ein:worksheet-execute-cell               |
| ~S-RET~ | ein:worksheet-execute-cell-and-goto-next |

Also ~SPC f s~ saves the notebook like you would a regular buffer.

*** Insert mode
In normal mode the following key bindings are defined:

| Key     | Function                                 |
|---------+------------------------------------------|
| ~C-RET~ | ein:worksheet-execute-cell               |
| ~S-RET~ | ein:worksheet-execute-cell-and-goto-next |

*** Traceback mode
In traceback mode the following key bindings are defined:

| key   | Function                               |
|-------+----------------------------------------|
| ~RET~ | ein:tb-jump-to-source-at-point-command |

| ~p~   | ein:tb-prev-item                       |

* Bonus
If you want to have a matplotlibrc that looks good with a dark background try
using [[https://gist.github.com/anonymous/80219c49cb674d01e6b5fab94e759f54][this]] =matplotlibrc=. Plot background is always transparent by default so
it will look okay for most dark themes out there.
