ubuntu14.04 下emacs 24 配置

目的： 配置emacs 24 适合编程开发

主要参考JerryZhang的配置（Emacs 简易教程）

http://www.perfect-is-shit.com/emacs-simple-tutorial.html#tocAnchor-1-16-5

https://gitcafe.com/JerryZhang/Emacs-Config

优点： 插件少 基本功能都比较全，emacs 配置后启动比较快速

安装过程如下：

• git clone https://gitcafe.com/JerryZhang/emacs-config.git ~/.emacs.d （后面的地址可更换，下载后复制到~/.emacs.d目录下）
• cd ~/.emacs.d/lisp/helm && make

安装完成后

init.el更改内容

• 显示行号.去掉(global-linum-mode 1)前的分号（;）

• 增加切换buffer的快捷键

;;------------------------------------------------------------------------------
;; 快速切换至上个buffer
;; Shift+TAB切换至上个buffer
;;------------------------------------------------------------------------------
(global-set-key (kbd "<backtab>") #'(lambda ()
                                      (interactive)
                                      (switch-to-buffer (other-buffer (current-buffer) 1))))

• 增加 speedbar

下载 sr-speedbar.el 至.emacs.d/lisp目录下

init.el 添加代码

;;------------------------------------------------------------------------------
;; 使用speedbar <F6>切换speedbar的开启状态
;; s键在speedbar中搜索 u键回到上一个目录
;;------------------------------------------------------------------------------
(require 'sr-speedbar)
(global-set-key (kbd "<f6>") (lambda()
                               (interactive)
                               (sr-speedbar-refresh)
                               (sr-speedbar-toggle)
                               (unless (sr-speedbar-exist-p)
                                 (kill-buffer "*SPEEDBAR*"))))
(require 'speedbar)
(define-key speedbar-mode-map (kbd "s")
  #'(lambda ()
      (interactive)
      (beginning-of-buffer)
      (isearch-forward)))
(define-key speedbar-mode-map (kbd "u")
  #'(lambda ()
      (interactive)
      (speedbar-up-directory)))

　开启ido支持

;;------------------------------------------------------------------------------
;; 开启ido 支持
;;------------------------------------------------------------------------------
(require 'ido)
(ido-mode t)
;;ido模式中不保存目录列表,解决退出Emacs时ido要询问编码的问题。
(setq ido-save-directory-list-file nil)

提供的F*快捷键　

F2 grep

F3 eshell

F4 插入当前时间

F5 compile

F6 speedbar

安装cscope

sudo apt-get install cscope

xcscope.el 使用:

• cscope-indexer -r : 在根目录下递归生成数据库
• C-c s a : Set initial directory;
• C-c s A : Unset initial directory;
• C-c s I : create list of files to index;
• C-c s s : Find symbol;
• C-c s d : Find global definition;
• C-c s c : Find functions calling a function;
• C-c s C : Find called functions (list functions called from a function);
• C-c s t : Find text string;
• C-c s e : Find egrep pattern;
• C-c s f : Find a file;
• C-c s i : Find files #including a file;
• C-c s b : Display cscope buffer;
• C-c s u : back

在使用gdb调试程序时

　　先M-x gdb 打开gdb调试

　　然后M-x gdb-many-windows 使用多窗口查看调试过程
