emacs配置大全(cedet+ecb+cscope+gdbui)jzj

原文地址：http://blog.csdn.net/nhczp/article/details/1862695

本文主要讨论以下几方面的设置：
1.字体
2.cedet
3.ecb
4.cscope
5.gdb-many-window
6.行号
7.缩进

 

环境：
openSUSE 10.2
默认装的是Emacs 21，我从网上下了Emacs 22.1的tar包，编译安装。

1.字体
    默认的字体非常之小，以下是一篇非常详细的Emacs下设置字体的教程
http://www.yuanma.org/data/2006/0503/article_355.htm
可惜太长了，长到我实在是懒得看。我抄了个现成的：
(set-default-font "-adobe-courier-medium-r-normal--14-100-100-100-m-90-iso10646-1")
或者只写：
(set-default-font "10x20")
第二种方法效果不错：）

2.cedet
   下载cedet: http://cedet.sourceforge.net/
按照INSTALL安装就行，然后设置.emacs。INSTALL里有一段关于设置的，粘贴过来即可，另外最好在.emacs中设一个speedbar的快捷键:
(global-set-key [(f4)] 'speedbar-get-focus)
这样按一个F4，speedbar就出来了。
再加一条：
  (define-key c-mode-base-map [(meta ?/)] 'semantic-ia-complete-symbol-menu)
于是，在程序中按下Alt+/，就会弹出菜单让你自动补全。

3.ecb
    http://ecb.sourceforge.net/
.emacs里：
(add-to-list 'load-path "~/software/ecb-2.32")
;;(require 'ecb)
(require 'ecb-autoloads)
打开emacs，然后M-x ecb-activate即可打开ecb。

4.cscope
   这个应该和ecb的有些功能是重复的
先装好cscope,再把/cscope-15.6/contrib/xcscope目录下的xcscope.el加载到emacs中去:
(add-to-list 'load-path "~/software/cscope-15.6/contrib/xcscope")
(require 'xcscope)

之后先M-x !，然后cscope -b，之后就可以在源代码中进行跳转了。命令见cscope菜单
这里有篇讲怎么在emacs下安装和使用cscope的：

5.gdb-many-window
   这个功能插件可以使emacs的调试界面像VC一样，有watch, stacktrace等窗口，真正实现图形化gdb.
下载：
http://www.inet.net.nz/~nickrob/multi-gud.el
http://www.inet.net.nz/~nickrob/multi-gdb-ui.el
设置.emacs:
(setq gdb-many-windows t)
;;...
(load-library "multi-gud.el")
(load-library "multi-gdb-ui.el")
在emacs中编译好程序，然后M-x gdb，连按两次ret，多窗口gdb就出来了

还不行的看详细官方教程：http://www.inet.net.nz/
一遍使用gdb-ui的教程：
http://blog.chinaunix.net/u/5958/showart_137996.html

6.行号

见:

http://ann77.stu.cdut.edu.cn/EmacsDisplayLineNumber.html

然后在.emacs里加上：

(add-to-list 'load-path "~/backup/emacs") ;;这行根据你放el文件的地方改

(require 'display-line-number)
(global-display-line-number-mode 1)
;;(setq display-line-number-mode-on t)
(add-hook 'c-mode-hook 'display-line-number-mode)
(add-hook 'cc-mode-hook 'display-line-number-mode)

这个感觉比setnu.el那个好用，setnu.el有时候行号会乱掉的。
7.缩进
emacs的缩进方式和其它编辑器有些不同，text-mode下不能tab，只能用C-q tab才行。
c-mode或cc-mode下缩进只有2格，这个当然不符合大多数人的习惯，如果要设为4：
(add-hook 'c-mode-hook
          '(lambda ()
             (c-set-style "Stroustrup")))
如果要设成8:
options->Customize Emacs->Browse Customization Group->Programming->Language->C->C-Basic-offset，设成8就行，保存
