ubuntu vim+ctags+taglist+cscope

Vi大家都很熟悉,某些情况下它是我们在Linux下唯一可用的文本编辑器。其实我们平时所指的VI其实是VIM(ViImproved,VI增强版)。有人常常拿VIM和emacs比较,VIM尽管不象emacs那样有那么多的功能,但是比emacs更方便、好用。VIM简单易用,只要看看VIM自带的vitutor,大约只要20分钟就能掌握VIM的用法。对于Linux下的C/C++的程序员,使用VIM+Ctags的组合来写程序也许是最佳的选择。^_^

VI的使用方法这里就不罗嗦了,本文假设大家已花了20分钟学习过了vitutor。 ^_^
        本节我们主要讲一下Ctags这个程序。尽管ctags也可以支持其它编辑器,但是它正式支持的只有VIM。并且VIM中已经默认安装了Ctags,它可以帮助程序员很容易地浏览源代码。
熟练的使用ctags仅需记住下面七条命令:(很简单吧,呵呵)
        1. $ ctags –R *      ($ 为Linux系统Shell提示符)
        2.  $ vi –t tag         (请把tag替换为您欲查找的变量或函数名)
        3. :ts                                (ts 助记字:tags list, “:”开头的命令为VI中命令行模式命令)
        4. :tp                                (tp 助记字:tags preview)---此命令不常用,可以不用记
        5. :tn                                (tn 助记字:tags next) ---此命令不常用,可以不用记
        6. Ctrl + ]
        7. Ctrl + T
        
下面我们逐条的解释上面的命令:
“$ ctags –R *”:“-R”表示递归创建,也就包括源代码根目录(当前目录)下的所有子目录。“*”表示所有文件。这条命令会在当前目录下产生一个“tags”文件,当用户在当前目录中运行vi时,会自动载入此tags文件。Tags文件中包括这些对象的列表:
用#define定义的宏
枚举型变量的值
函数的定义、原型和声明
名字空间(namespace)
类型定义(typedefs)
变量(包括定义和声明)
类(class)、结构(struct)、枚举类型(enum)和联合(union)
类、结构和联合中成员变量或函数
VIM用这个“tags”文件来定位上面这些做了标记的对象。

剩下的命令就是定位这些对象的方法:
“$ vi –t tag” :在运行vim的时候加上“-t”参数,例如:
[/usr/src]$ vim -t main
这个命令将打开定义“main”(变量或函数或其它)的文件,并把光标定位到这一行。如果这个变量或函数有多处定义,在VI命令行模式“:ts”命令就能列出一个列表供用户选择。    “:tp”为上一个tag标记文件,“:tn”为下一个tag标记文件。当然,若当前tags文件中用户所查找的变量或函数名只有一个,“:tp,:tn”命令不可用。 :(
最方便的方法是把光标移到变量名或函数名上,然后按下“Ctrl+]”,这样就能直接跳到这个变量或函数定义的源文件中,并把光标定位到这一行。用“Ctrl+t”可以退回原来的地方。即使用户使用了N次“Ctrl+]”查找了N个变量,按N次“Ctrl+t”也能回到最初打开的文件,它会按原路返回 。 ^_^

注意:运行vim的时候,必须在“tags”文件所在的目录下运行。否则,运行vim的时候还要用“:settags=”命令设定“tags”文件的路径,这样vim才能找到“tags”文件。在完成编码时,可以手工删掉tags文件(帚把不到,灰尘不会自己跑


在Ubuntu中vim的配置文件存放在/etc/vim目录中,配置文件名为Ubuntu vimrc


前提:已经安装了vim,建议安装vim-full,即:sudoapg-get install vim-full
   
    1.ctags:

    下载ctags,可从官网上下载,如:ctags-5.7.tag.gz

    tarxzvf ctags-5.7.tag.gz

    cdctags-5.7

    ./configure

    make

    sudomake install

    具体操作时目录可能不一样

    2.taglist:

    cd~

    mkdir.vim

    cd.vim

    mkdirplugin

    unzip(path自定)/taglist_45.zip

    ls

    //解压成功会在.vim下生成两个文件夹,doc, plugin

    测试一下插件是否安装好,可以运行一下命令

    1、ctags--version,有信息则说明安装好了

    2、进入一个原文件,vitest.c,进入命令模式,输入命令":Tlist",如果出现左右两栏分栏显示,则说明OK

    把ctags关联到taglist

    vi~/.vim/plugin/taglist.vim

    在命令行模式下输入命令查抄":/loaded_taglist"

    找到后,在该行前面加上如下行:

    letTlist_Ctags_Cmd="/usr/bin/ctags""目录可能有变,或许是/usr/local/bin/ctags

    OK

    到你想浏览的目录下

    ctags-R

    vitest.c

    :syntaxon //打开语法高亮

    :setcindent //打开自动缩进

    :Tlist//OK

3.cscope

sudo apt-get install cscope


安装好开发工具后,配置一下.vimrc文件在用户的主目录下:

我的.vimrc如下:

set hlsearch
set ai
syntax on
set number
set nocompatible
set columns=80
filetype on
set history=1000
set autoindent
set smartindent
set tabstop=4

"               '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.

    "   '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

    " If you don't like using 'CTRL-@' or CTRL-\, , you can change some or all

    " (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
