本人的linux emacs 配置文件

用过一段时间emacs后，还是建议大家直接用高手的配置，熟练之后可以自己定制，参考：一年成为Emacs高手(像神一样使用编辑器)

此配置文件需要下载以下插件：cscope、auto-complete、yasnippet

;;turn off the backup
(setq make-backup-files nil)
;; tab and space 
;; when true, emacs use mixture of tab and space to achieve offset 
(setq-default indent-tabs-mode nil) 
;; control length used to offset. 
(setq-default c-basic-offset 4) 
;; control how emacs explain TAB. 
(setq-default tab-width 4) 




;;最大化  
(defun my-maximized ()  
  (interactive)  
  (x-send-client-message  
    nil 0 nil "_NET_WM_STATE" 32  
    '(2 "_NET_WM_STATE_MAXIMIZED_HORZ" 0)  
  )  
  (x-send-client-message  
    nil 0 nil "_NET_WM_STATE" 32  
    '(2 "_NET_WM_STATE_MAXIMIZED_VERT" 0)  
  )  
)  
;;启动时最大化  
(my-maximized) 




;;启动时去掉欢迎界面

(setq show-paren-style 'parentheses)

;;先下载window-numbering.el，放到/usr/share/site-lisp
(require 'window-numbering)
(window-numbering-mode 1)






;;在buffer左侧显示行号
