Welcome to the best collection of emacs extensions ever

I’m collecting and customizing the perfect environment for python development, using the most beautiful emacs customization to obtain a really modern and exciting (yet stable) way to edit text files.

In the package are included also a lot of other packages and configurations, it’s an upstart for clean emacs installations, these configuration however are very similar to emacs-starter-kit and I suggest you to give it a try, emacs-for-python is designed to work with it (instruction below).

Features

The package is split into various files, in this way it’s very easy to include what you really need.

Python Related

Ropemacs (Custom) : A refactoring library
Auto Completion with rope (Custom) : Tested to work well with Rope
Flymake + pyflakes (Custom): Highlight errors on the fly, improved from the standard version
Virtualenv : Original, In-development tool for using virtualenv in emacs.
Custom Yasnippet Snippets
Cython Mode: a mode for highlighting cython files
latest python.el (fgallina/python.el)
nosetests integration (nose.el)

Editing Packages

Open Next Line: C-o will open a line under the cursor (very similar to vim o)
Auto Completion: Wonderful package for auto complete anything in emacs
Yasnippet: Snippets on steroids
Parentheses pairing (Custom): Bug-free parentheses pairing using skeletons.
smart-operator: Automatically adds spaces around arithmetic operators.

Configurations

ido activation
ibuffer instead of buffer menu
eshell configuration

Keybindings

Copy-Cut-Paste from clipboard with Super-C Super-X Super-V
Calc Mode remapping to M-c
M-Tab remapped to C-Tab to avoid collisions with the desktop manager
nose keybindings

Installation

Put the emacs-for-python directory in .emacs.d directory (or any other), the add this line in your .emacs, it will enable all the features of emacs-for-python package (editing configuration, keybindings, python stuff etc…)

(load-file "/path/to/emacs-for-python/epy-init.el")

You may want to enable only some of the features provided by emacs-for-python, in this case just enable some of them:

(add-to-list 'load-path "path/to/emacs-for-python/") ;; tell where to load the various files
(require 'epy-setup)      ;; It will setup other loads, it is required!
(require 'epy-python)     ;; If you want the python facilities [optional]
(require 'epy-completion) ;; If you want the autocompletion settings [optional]
(require 'epy-editing)    ;; For configurations related to editing [optional]
(require 'epy-bindings)   ;; For my suggested keybindings [optional]
(require 'epy-nose)       ;; For nose integration

There is another nice tutorial on how to install emacs-for-python here: http://maddemcode.com/python/emacs-and-python-the-definitive-answer/

Configuring the flymake checker

New in version 0.3: I changed the way you configure your checkers, now there is no predefined checker and you have to configure it by your own.

The good news is that it is extremely simple to configure your own command, for example to configure the pyflakes checker install it and put in your customization file (.emacs):

(epy-setup-checker "pyflakes %f")

Obviously you can substitute the “”pyflakes %f”“ with whatever you want, you just have to keep in mind that “%f“ will be substituted with the file which is being checked.

Adding the django snippets

The django snippets comes as an option, you can load them using:

(epy-django-snippets)

As a command using M-x or putting it in your .emacs.

ipython integration

Ipython can be integrated with python-mode. Clicking on the Python->Start interpreter menu entry will spawn an ipython shell instead of a python one. To enable the feature put this line in your .emacs:

(epy-setup-ipython)

line highlighting

You may want to enable this feature with the color you prefer, to do so, drop one of the following lines in your .emacs

(global-hl-line-mode t) ;; To enable
(set-face-background 'hl-line "black") ;; change with the color that you like
                                       ;; for a list of colors: http://raebear.net/comp/emacscolors.html

Highlight Indentation

Interesting way to have a visual clue on how the code is indented:

(require 'highlight-indentation)
(add-hook 'python-mode-hook 'highlight-indentation)

disabling the auto-pairing of parenthesis

To disable the auto-pairing, drop the following line:

(setq skeleton-pair nil)

Nosetests keybindings

First of all, install nosetests. Then open a python file in your project and: “C-c a“: run all test “C-c m“: run tests in the module “C-c .“: run test under cursor

“C-c p a“, “C-c p m“, “C-c p .“: same as above but drop in pdb when there’s an error (Very useful!)

Disabling ropemacs

Just add the line to your .emacs

(setq epy-enable-ropemacs nil)

Installation with emacs-starter-kit

I’ve built up a little fork of emacs starter kit that is greatly integrated with emacs-for-python, it seems the best solution to me!

The repo is at this address: http://github.com/gabrielelanaro/emacs-starter-kit

Remember that customization to emacs-starter-kit are done to a custom.el file, and so you can substitute your distribution of emacs-starter-kit and you have to copy just your customization file.
