vim是一般
Linux系统的自带工具，无须下载。
sudo apt-get install vim
安装ctags,cscope
sudo apt-get install exuberant-ctags
cscope
安装taglist
taglist配合ctags使用，本身是vim的插件，在vim官网有下载
http://www.vim.org/scripts/script.PHP?script_id=273
下载后解压，检查是否有~/.vim目录，如果没有就建立一个：mkdir
~/.vim
解压出来的2个文件夹doc和plugin拷贝到~/.vim目录下
配置cscope的vim插件
wget http://cscope.sourceforge
.NET/cscope_maps.vim
将下载的cscope_map.vim文件放在~/.vim/plugin目录中
vim的配置文件
set tabstop=4
set shiftwidth=4
set expandtab
set nu
set hlsearch
set incsearch
set ruler
set softtabstop=4
"set autochdir
set autoread
set autoindent
set smartindent
set ruler
"set list
set showmatch
set paste
syntax on
filetype plugin indent on
nnoremap <silent> <F8> : TlistToggle<CR>
let Tlist_Use_Right_Window = 1
let Tlist_Exit_OnlyWindow = 1
let Tlist_Show_One_File = 1
let Tlist_File_Fold_Auto_Close = 1
let Tlist_Display_Prototype = 1
set tags=tags
function! UpdateCtags()
let curdir=getcwd()
while !filereadable("./tags")
cd ..
if getcwd() == "/"
break
endif
endwhile
if filewritable("./tags")
!ctags -R --file-scope=yes --langmap=c:+.h --languages=c,c++ --links=yes --c-kinds=+p --c++-kinds=+p --fields=+iaS --extra=+q
TlistUpdate
endif
execute ":cd " . curdir
endfunction
nnoremap <silent> <F11> : call UpdateCtags()<CR>
至此，工具和配置已经完毕，接下来就可以直接使用了。
将以下脚本添加到~/.bashrc文件
ctags_cscope_func() {
ctags -R --file-scope=yes --langmap=c:+.h --languages=c,c++ --links=yes --c-kinds=+p --c++-kinds=+p --fields=+iaS --extra=+q
find . -iname '*.c' -o -iname '*.cpp' -o -iname '*.h' -o -iname '*.hpp' -o -iname "*.cc" > cscope.files
cscope -Rbkq -i cscope.files
}
alias ccsi='ctags_cscope_func'
添加完毕，执行source ~/.bashrc，这样我们就可以使用ccsi命令来创建ctags和cscope的
数据库了。
进入你想建立符号库的工程的源码根目录，执行ccsi命令
errong.leng@VDBS1444:~/google_blink/src$ ccsi
命令执行完毕，应该会生成如下几个文件，表示创建成功了。
cscope.files cscope.in.out cscope.out cscope.po.out tags
接下来就可以像使用sourceinsight一样的，用VIM来编辑你的代码了。
打开VIM，按下F8，可以打开tag list，按下F11可以更新符号库。
注意事项：务必要在执行ccsi命令的地方，即你的工程的源码的根目录使用VIM。
How to use ctags
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).
more details please refer to http://ctags.sourceforge
.Net/ctags.html
How to use taglist:
" <enter> : Jump to tag definition
" o : Jump to tag definition in new window
" p : Preview the tag definition
" <space> : Display tag prototype
" u : Update tag list
" s : Select sort field
" d : Remove file from taglist
" x : Zoom-out/Zoom-in taglist window
" + : Open a fold
" - : Close a fold
" * : Open all folds
" = : Close all folds
" [[ : Move to the start of previous file
" ]] : Move to the start of next file
" q : Close the taglist window
" <F1> : Remove help text
more details please refer to http://vim-taglist.sourceforge.net/manual.html
How to use cscope:
打开VIM，输入:cs f c|d|e|f|g|i|s|t
cscope commands:
add : Add a new database (Usage: add file|dir [pre-path] [flags])
find : Query for a pattern (Usage: find c|d|e|f|g|i|s|t name)
c: Find functions calling this function
d: Find functions called by this function
e: Find this egrep pattern
f: Find this file
g: Find this definition
i: Find files #including this file
s: Find this C symbol
t: Find this text string
help : Show this message (Usage: help)
kill : Kill a connection (Usage: kill #)
reset: Reinit all connections (Usage: reset)
show : Show connections (Usage: show)
