My Emacs Python Setup

You can find information regarding my emacs Python setup literate emacs initialization file found here: https://github.com/julienchastang/dotemacs/blob/master/settings.org

Python Related Modes I Use

python-mode.el and python.el

Various keystroke optimizations for faster editing/code folding.

ein

IPython notebook client in Emacs!

Thanks Takafumi Arakaki!

jedi

Python auto-completion for Emacs

Thanks Takafumi Arakaki!

Python Related Modes I Don’t Use (but maybe I should)

ropemacs

noseemacs

ipython (in contrast to ein)

Could not get the interpreter to display matplotlib figures. According to the BoF it is possible to display plots with Qt.

Other stuff I find useful for Python development

magit

An Emacs mode for Git.

git-gutter

Icons in the “gutter” area indicating whether a line has been inserted, modified or deleted.

IDO

A mode-line completion engine

smex

Built on top of IDO, it provides a convenient interface to your recently and most frequently used commands.

auto-complete

Auto completion with popup menu.

Org mode

Your life in plain text

Babel for org-mode

Execute source code within Org-mode documents

Challenges/Questions

What is the status of ein, especially with IPyNB 2.0?

conda create -n netcdf-np18-py27 -c julienchastang netcdf numpy  ipython-notebook=1.1

How do people deal with virtual environments within emacs?

e.g.,

source activate blah

Code Sprint

Organize a code sprint to help emacs ipython notebook (ein) mode.

Github doesn't seem to support pull requests for gists, but I've made a small addition to this gist here:

https://gist.github.com/abingham/e198ffe8d1a8eb689cf8/812e8aeda103ea797a94e4e7396cd4d2b9618e28

I just added a mention of tkf's python-environment package which came up a few times in the BoF. If there's a better way to handle these kinds of additions, let me know. This feels a bit clunky.
