IPython notebook client in Emacs

EIN -- Emacs IPython Notebook Build Status

--- or EIN Is not only for Notebooks.

Note

It is stable enough for my day to day work, but I can't guarantee the safety for your notebook data. So please make sure you have backup.

Features

Emacs IPython Notebook (EIN) provides a IPython Notebook client and integrated REPL (like SLIME) in Emacs. While EIN makes notebook editing very powerful by allowing you to use any Emacs features, it also expose IPython features such as code evaluation, object inspection and code completion to the Emacs side. These features can be accessed anywhere in Emacs and improve Python code editing and reading in Emacs.

Highlighted features:

  • Copy/paste cells, even to/from different notebooks.
  • Console integration: You can easily connect to kernel via console application. This enables you to start debugging in the same kernel. It is even possible to connect console over ssh.
  • IPython kernel can be "connected" to any buffers. This enables you to evaluate buffer/region using same kernel as notebook. Notebook goodies such as tooltip help, help browser and code completion are available in these buffers.
  • Jump to definition (go to the definition by hitting M-. over an object).

Other notebook features:

  • Inline images
  • Auto/manual-completion
  • Popup (tooltip) help
  • Syntax highlighting in each cell types (Python/Markdown)
  • Help browser (opens when executing function?)
  • Traceback viewer

Quick try

This is a quick and clean way to try EIN separately from your Emacs setting. If you want to try EIN but think preparing all the requirements is too much, try this!:

git clone git://github.com/tkf/emacs-ipython-notebook.git
cd emacs-ipython-notebook/
lisp/zeroein.el

This will launch a new Emacs instance.

You can use environment variable EMACS to control Emacs executable to use.:

EMACS=emacs-snapshot lisp/zeroein.el

The above command requires /bin/sh. If the above command does not work (e.g., you are using MS Windows), try the following command:

emacs -Q -l lisp/zeroein.el

Requirements

  • IPython 0.12 or higher.
  • websocket.el 0.9
  • request.el >= 0.2
  • (optional) mumamo developmental version: It will be automatically loaded when it is on the path. The official way to setup path is to load nXhtml.
  • (optional) markdown-mode
  • (optional) python-mode: It should work with either python.el or python-mode.el. Fabian Gallina's python.el is required to use ein:console-open command.
  • (optional) auto-complete.el You need to configure subpackage ein-ac to enable this feature.
  • (optional) smartrep.el: This package enables you to omit typing prefix keys (e.g., C-c C-n C-n C-n ... instead of C-c C-n C-c C-n C-c C-n ...). You need to configure subpackage ein-smartrep to enable this feature.

Also, EIN heavily relies on standard Emacs libraries including EWOC, EIEIO and json.el. EIN is currently tested against Emacs 23.3 and 24.3. It is known to work in Emacs 23.2, 24.1 and 24.2.

Usage

  1. Install module. Put Emacs lisp ein*.el files and Python file ein.py in your load path. See online documentation for more information.

  2. Require module:

    (require 'ein)
    
  3. Start IPython notebook server.

  4. Hit M-x ein:notebooklist-open to open notebook list.

Subpackages

Enable auto-complete.el:

(setq ein:use-auto-complete t)
;; Or, to enable "superpack" (a little bit hacky improvements):
;; (setq ein:use-auto-complete-superpack t)

Enable smartrep.el:

(setq ein:use-smartrep t)

Keybinds - Connect

In Python (or any other) buffer, you can connect to any open notebook by M-x ein:connect-to-notebook then choose appropriate notebook. After connecting to the notebook (and hence its kernel), the following commands are available.
