Vim+Cscope

1、安装Cscope

sudo apt-get install cscope

2、在/etc/vim/vimrc文件中加入以下内容

"enable the cscope in vim
if filereadable("cscope.out")
    cs add cscope.out
endif

3、进入想要看的文件夹目录： 例/home/linx/kernel/linux-3.6.3/drivers/char

cd kernel/linux-3.6.3/drivers/char/

4、建立索引

cscope -Rbq
#-R            Recurse directories for files.
#-b            Build the cross-reference only.
#-q            Build an inverted index for quick symbol searching.

5、打开想要查看的文件： 例 misc.c

vim misc.c

6、使用底行添加路径

:cs add ~/kernel/linux-3.6.3/drivers/char/cscope.out ~/kernel/linux-3.6.3/drivers/char 

7、索引： 例 static LIST_HEAD(misc_list);

:cs find s LIST_HEAD

8、cscope强化：在/etc/vim/vimrc中加入如下内容

"use the Ctrl+Shift+\ and [sgctefid] shorted for the code cs find [sgctefid]
nmap <C-\>s :cs find s <C-R>=expand("<cword>")<CR><CR>
nmap <C-\>g :cs find g <C-R>=expand("<cword>")<CR><CR>
nmap <C-\>c :cs find c <C-R>=expand("<cword>")<CR><CR>
nmap <C-\>t :cs find t <C-R>=expand("<cword>")<CR><CR>
nmap <C-\>e :cs find e <C-R>=expand("<cword>")<CR><CR>
nmap <C-\>f :cs find f <C-R>=expand("<cfile>")<CR><CR>
nmap <C-\>i :cs find i ^<C-R>=expand("<cfile>")<CR>$<CR>
nmap <C-\>d :cs find d <C-R>=expand("<cword>")<CR><CR>

9、now, enjoy it.
