emacs
[color=red]F10是菜单[/color]
编译el

emacs --batch -f batch-byte-compile haoning.el

查看变量定义
[color=red]c-h v[/color]

[b]etags使用[/b]

find -name "*.[chCH]" -exec etags -a {} ;
　　或
find . -name "*.[chCH]" -print | etags -
创建好tag表后，告知emacs。
　　M-x visit-tags-table
在.emacs中加入这样的语句：
　　(setq tags-file-name "~/sim973/src/TAGS")
M-. 查找一个tag，比如函数定义类型定义等。
　　C-u M-. 查找下一个tag的位置
　　M-* 回到上一次运行M-.前的光标位置。
　　M-TAB 自动补齐函数名。

[color=darkred]安装auto-complete后，只要emacs打开的文件都可以自动补全，
比如看的是c的代码，
我们可以把TAGS复制成TAGS.c然后，c-x c-f 打开TAGS.c
这样就可以即使用etags又使用自动补全了[/color]


.emacs

(require 'package)  
(dolist (source '(("elpa" . "http://tromey.com/elpa/")  
                  ("melpa" . "http://melpa.milkbox.net/packages/")  
                  ))  
(add-to-list 'package-archives source t))
(package-initialize)

(load-file "~/.emacs.d/hao-base.el")
(load-file "~/.emacs.d/hao-complete.el")
(load-file "~/.emacs.d/hao-study.el")
;(load-file "~/.emacs.d/hao-js.el")
(setq tags-file-name "/root/haoning/nginx-1.9.4/TAGS")

基本设置
hao-base.el

(setq indent-tabs-mode nil)
(setq default-tab-width 4)
(setq tab-width 4)
(show-paren-mode t)
(setq frame-title-format "[email protected]%b")

自动提示,需要list-packages安装auto-complete,
auto-yasnippets
hao-complete.el

;;m-x list-packages;  c-s auto-complete
(require 'auto-complete)
(require 'auto-complete-config)
(global-auto-complete-mode t)
(autoload 'auto-complete-mode "auto-complete-mode" nil t) 
;(add-to-list 'ac-dictionary-directories "~/.emacs.d/elpa/auto-complete-20150618.1949/dict")
(ac-config-default)
(setq ac-use-quick-help nil)
(setq ac-auto-start 4) ;; 输入4个字符才开始补全
(global-set-key "\M-/" 'auto-complete) ;; 补全的快捷键，用于需要提前补全
(setq ac-auto-show-menu 0.8);; Show menu 0.8 second later
;; 选择菜单项的快捷键
(setq ac-use-menu-map t)
(define-key ac-menu-map "\C-n" 'ac-next)
(define-key ac-menu-map "\C-p" 'ac-previous)
(setq ac-menu-height 15);; menu设置为15 lines

;;;;;yasnippets
(defun dot-emacs (relative-path)
  "Return the full path of a file in the user's emacs directory."
  (expand-file-name (concat user-emacs-directory relative-path)))
(require 'yasnippet)
(yas/initialize)
(yas/load-directory (dot-emacs "elpa/yasnippet-20151108.1505/snippets"))
