Python и emacs, несколько удобных решений

(require ‘auto-complete-config)
(global-auto-complete-mode t)

(require ‘yasnippet)
(yas/initialize)
(yas/load-directory “~/.emacs.d/snippets”)

sudo apt-get install pymacs
sudo apt-get install mercurial
mkdir /tmp/rope && cd /tmp/rope
hg clone http://bitbucket.org/agr/rope
hg clone http://bitbucket.org/agr/ropemacs
hg clone http://bitbucket.org/agr/ropemode

Теперь нам понадобится easy_install
wget http://peak.telecommunity.com/dist/ez_setup.py
sudo python ez_setup.py
sudo easy_install rope
ln -s ../ropemode/ropemode ropemacs/
sudo easy_install ropemacs

6. Устанавливаем pyflakes для автоматической проверки синтаксиса.
sudo apt-get install pyflakes

7. Создаем файл init_python.el в нашей дирректории ~/.emacs.d/ и вставляем туда этот код:

(autoload 'python-mode "python-mode" "Python Mode." t)
(add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode))
(add-to-list 'interpreter-mode-alist '("python" . python-mode))
(require 'python-mode)
(add-hook 'python-mode-hook
(lambda ()
(set-variable 'py-indent-offset 4)
;(set-variable 'py-smart-indentation nil)
(set-variable 'indent-tabs-mode nil)
(define-key py-mode-map (kbd "RET") 'newline-and-indent)
;(define-key py-mode-map [tab] 'yas/expand)
;(setq yas/after-exit-snippet-hook 'indent-according-to-mode)
(smart-operator-mode-on)
))
;; pymacs
(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-exec "pymacs" nil t)
(autoload 'pymacs-load "pymacs" nil t)

(pymacs-load "ropemacs" "rope-")
