* iPython Notebook contribution layer for Spacemacs (WIP)
** 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 micro-State or leader key
- Lazy-loading

** TODO List
- Maybe it'd be better if there was a state for this
- Make more keybinding to =connect= to a python buffer.
- Deleting visual regions don't work, find out why.
- This is a WIP, feel free to collaborate.

** Install
*** Layer
#+begin_src emacs-lisp
  (setq-default dotspacemacs-configuration-layers '(ipython))
#+end_src
*** Dependencies
Install iPython > 3
#+begin_src sh
  pip install ipython
#+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 micro-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 micro state or the usual evil-leader.

**** Micro-state: =ipython-notebook= 
Once you are in the ipython notebook you can activate the micro-state with
=SPC e i n=

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

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