1.taglist
注意：taglist依赖于ctags，所以要先装ctags，否则taglist装了也没法用！
（1）将taglist_45.zip解压得到的两个文件夹：doc和plugin 放到 ~/.vim文件夹里面，如果主目录下没有这个隐藏的文件夹，就建一个。
（2）
plugin/taglist.vim – taglist插件
doc/taglist.txt - taglist帮助文件
（3）常用快捷键
ctrl＋ww 在列表和源文件中切换
ctrl + ] 查看函数定义
ctrl + o 返回上一级文件。
gf 查看头文件
gd 转到当前光标所指的局部变量的定义处。
* 转到当前光标所在单词的下一次出现的地方。
# 转到当前光标所在的单词的上一次出现的地方。
跳到光标下tag所定义的位置，用鼠标双击此tag功能也一样
o 在一个新打开的窗口中显示光标下tag
显示光标下tag的原型定义
u 更新taglist窗口中的tag
s 更改排序方式，在按名字排序和按出现顺序排序间切换
x taglist窗口放大和缩小，方便查看较长的tag
+ 打开一个折叠，同zoctags常用快捷键ctags常用快捷键
- 将tag折叠起来，同zc
* 打开所有的折叠，同zR
= 将所有tag折叠起来，同zM
[[ 跳到前一个文件
]] 跳到后一个文件
q 关闭taglist窗口
2.ctags
（1）安装ctags ： sudo apt-get install ctags
（2）使用
ctags -R 对当前目录下的文件递归产生tags文件。
ctags file.c
（3）在.vimrc文件中添加配置
:TlistToggle 或 :Tlist 显示函数列表
在.vimrc文件中加上键盘映射
map :Tlist
这样我就可以使用快捷键F8直接进入tlist模式了。这里注意和 ： 之间有空格的。
在.vimrc下加入一下两行
set tags=tags;
set autochdir
这样使用tags时可以首先在当前目录下查找tags文件，如果没有则转到父目录查找。依次向上。

:help helptags
:help taglist.txt
3.cscope
（1）仔细阅读了cscope的手册后发现，原来cscope在产生索引文件时，只搜索类型为 C, lex和yacc的文件(后缀名为.c, .h, .l, .y)，
C++的文件根本没有生成索引。不过按照手册上的说明，cscope支持c++和Java语言的文件。
于是按照cscope手册上提供的方法，先产生一个文件列表，然后让cscope为这个列表中的每个文件都生成索引。
为了方便使用，编写了下面的脚本来更新cscope和ctags的索引文件：
#!/bin/sh
find . -name "*.h" -o -name "*.c" -o -name "*.cc" > cscope.files
cscope -bkq -i cscope.files
ctags -R
-R : 在生成索引文件时，搜索子目录树中的代码
-b : 只生成索引文件，不进入cscope的界面
-k : 在生成索引文件时，不搜索 / usr / include目录
-q : 生成cscope . in . out和cscope . po . out文件，加快cscope的索引速度
将这个脚本保存到/usr/local/bin/cscopes.sh，以后就可以在源代码目录下使用sudo bash cscope.sh命令直接生成索引拉！
（2）cscope常用快捷键：
先按 ctrl+\ 然后
c: 查找该函数被调用的位置
d: 查找该函数调用了哪些函数
e: 查找指定的正规表达式 f: 查找指定的文件
g: 查找指定标识符的定义位置
i: 查找该文件在哪些地方被包含
s: 查找指定标识符的使用位置
t: 查找指定的文本字符串
需要上面的快捷键的话，还需要修改/etc/vimrc

" CSCOPE settings for vim
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
"
" This file contains some boilerplate settings for vim's cscope interface,
" plus some keyboard mappings that I've found useful.
"
" USAGE:
" -- vim 6: Stick this file in your ~/.vim/plugin directory (or in a
" 'plugin' directory in some other directory that is in your
" 'runtimepath'.
"
" -- vim 5: Stick this file somewhere and 'source cscope.vim' it from
" your ~/.vimrc file (or cut and paste it into your .vimrc).
"
" NOTE:
" These key maps use multiple keystrokes (2 or 3 keys). If you find that vim
" keeps timing you out before you can complete them, try changing your timeout
" settings, as explained below.
"
" Happy cscoping,

""""""""""""" My cscope/vim key mappings
"
" The following maps all invoke one of the following cscope search types:
"
" 's' symbol: find all references to the token under cursor
" 'g' global: find global definition(s) of the token under cursor
" 'c' calls: find all calls to the function name under cursor
" 't' text: find all instances of the text under cursor
" 'e' egrep: egrep search for the word under cursor
" 'f' file: open the filename under cursor
" 'i' includes: find files that include the filename under cursor
" 'd' called: find functions that function under cursor calls
"
" Below are three sets of the maps: one set that just jumps to your
" search result, one that splits the existing vim window horizontally and
" diplays your search result in the new window, and one that does the same
" thing, but does a vertical split instead (vim 6 only).
"
" I've used CTRL-\ and CTRL-@ as the starting keys for these maps, as it's
" unlikely that you need their default mappings (CTRL-\'s default use is
" as part of CTRL-\ CTRL-N typemap, which basically just does the same
" thing as hitting 'escape': CTRL-@ doesn't seem to have any default use).
" If you don't like using 'CTRL-@' or CTRL-\, , you can change some or all
" of these maps to use other keys. One likely candidate is 'CTRL-_'
" (which also maps to CTRL-/, which is easier to type). By default it is
" used to switch between Hebrew and English keyboard mode.
"
" All of the maps involving the macro use '^$': this is so
" that searches over '#include " return only references to
" 'time.h', and not 'sys/time.h', etc. (by default cscope will return all
" files that contain 'time.h' as part of their name).
" To do the first type of search, hit 'CTRL-\', followed by one of the
" cscope search types above (s,g,c,t,e,f,i,d). The result of your cscope
" search will be displayed in the current window. You can use CTRL-T to
" go back to where you were before the search.
"
nmap s :cs find s =expand("")
nmap g :cs find g =expand("")
nmap c :cs find c =expand("")
nmap t :cs find t =expand("")
nmap e :cs find e =expand("")
nmap f :cs find f =expand("")
nmap i :cs find i ^=expand("")$
nmap d :cs find d =expand("")
" Using 'CTRL-spacebar' (intepreted as CTRL-@ by vim) then a search type
" makes the vim window split horizontally, with search result displayed in
" the new window.
"
" (Note: earlier versions of vim may not have the :scs command, but it

nmap i :scs find i ^=expand("")$
nmap d :scs find d =expand("")
" Hitting CTRL-space *twice* before the search type does a vertical
" split instead of a horizontal one (vim 6 and up only)
"
" (Note: you may wish to put a 'set splitright' in your .vimrc
" if you prefer the new window on the right instead of the left
nmap s :vert scs find s =expand("")

nmap d :vert scs find d =expand("")
""""""""""""" key map timeouts
"
" By default Vim will only wait 1 second for each keystroke in a mapping.
" You may find that too short with the above typemaps. If so, you should
" either turn off mapping timeouts via 'notimeout'.
"
"set notimeout
"
" Or, you can keep timeouts, by uncommenting the timeoutlen line below,
" with your own personal favorite value (in milliseconds):
"
"set timeoutlen=4000
"
" Either way, since mapping timeout settings by default also set the
" timeouts for multicharacter 'keys codes' (like ), you should also
" set ttimeout and ttimeoutlen: otherwise, you will experience strange
" delays as vim waits for a keystroke after you hit ESC (it will be
" waiting to see if the ESC is actually part of a key code like ).
"
"set ttimeout
"
" personally, I find a tenth of a second to work well for key code
" timeouts. If you experience problems and have a slow terminal or network
" connection, set it higher. If you don't set ttimeoutlen, the value for
" timeoutlent (default: 1000 = 1 second, which is sluggish) is used.
"
"set ttimeoutlen=100
