1.  Create Project Directory

     

      http://hamisme.blogspot.com/2011/02/cscope.html 請參考這篇文章

2.  Create Reference file

      

     $ cd $HOME/xf86-video-intel-2.14.0

     $ ctags -R  $HOME/xf86-video-intel-2.14.0/xf86-video-intel-2.14.0/src/

     

     P.S. 這會在$HOME/xf86-video-intel-2.14.0底下產生tags的檔案來讓vim當作參考的檔案

3.  Use Vim Editor

     

     $ vim $HOME/xf86-video-intel-2.14.0/xf86-video-intel-2.14.0/src/intel_video.c

     

     P.S. 進入vim之後，可以隨便找個function或symbol，然後按Ctrl+]可以找到原本function或symbol的位置，如果是要返回原來的位置就按Ctrl+t就可以了。

HOW TO USE WITH VI

Vi will, by default, expect a tag file by the name "tags" in the current directory. Once the tag file is built, the following commands exercise the tag indexing feature:

	vi −t tag		Start vi and position the cursor at the file and line where "tag" is defined.
	:ta tag		Find a tag.
	Ctrl-]		Find the tag under the cursor.
	Ctrl-T		Return to previous location before jump to tag (not widely implemented).
