Python開発環境のためのemacs設定

Pythonで100本ノックをやってみて、いろいろ書くのに時間がかかったので、emacsに以下の内容を設定し、開発環境を改善した。

~/emacs.d/init.el
に以下の内容を追記

;; init.el --- Emacs configuration

;; INSTALL PACKAGES
;; --------------------------------------

(require 'package)

(add-to-list 'package-archives
	     '("melpa" . "http://melpa.org/packages/") t)

(package-initialize)
(when (not package-archive-contents)
  (package-refresh-contents))

(defvar myPackages
  '(better-defaults
    material-theme))

(mapc #'(lambda (package)
	  (unless (package-installed-p package)
	  (package-install package)))
      myPackages)

;; BASIC CUSTOMIZATION
;; --------------------------------------

(setq inhibit-startup-message t)
(load-theme 'material t) 
(global-linum-mode t) ;; enable line number globally

;;rectangular selection
(cua-mode t)
(setq cua-enable-cua-keys nil)

;;disable making back-up file
(setq make-backup-files nil)

;;active save history mode and keep 500 history records
(savehist-mode 1)
(setq history-length 500)

;; SETUP PYTHONMODE
;;---------------------------------------

(defvar myPackages
	'(better-defaults
	elpy ;;add elpy package
	material-theme))

;; active auto-complete by jedi
(elpy-enable)
(elpy-use-ipython)
(setq elpy-rpc-backend "jedi")

;; active flycheck instead of flymake
(when (require 'flycheck nil t)
	(remove-hook 'elpy-modules 'elpy-module-flymake)
	(add-hook 'elpy-mode-hook 'flycheck-mode))

(defvar myPackages
	'(better-defaults
	smartrep ;;add smartrep package
	material-theme))

(define-key elpy-mode-map (kbd "C-c C-v") 'helm-flycheck)
(require 'smartrep)
(smartrep-define-key elpy-mode-map "C-c"
	'(("C-n" . flycheck-next-error)
	("C-p" . flycheck-previous-error)))

;; setup indent hiright
(set-face-background 'highlight-indentation-face "#313131")
(set-face-background 'highlight-indentation-current-column-face "#777777")
(add-hook 'elpy-mode-hook 'highlight-indentation-current-column-mode)

;;(setq twittering-curl-program "/usr/bin/curl")

;; init.el ends here
