vim+ctags+taglist插件安装使用vim+ctags+taglist插件安装使用

From:http://www.blogjava.net/zellux/archive/2007/06/12/123556.html

For using taglist plugin,you must install ctags plugin first.
1.ctags
（1）到 http://ctags.sourceforge.net/下载ctags源码ctags-5.6.tar.gz
http://prdownloads.sourceforge.net/ctags/ctags-5.6.tar.gz

windows user need to set a variable in "_vimrc" file lied in you $vim home directory.

let Tlist_Ctags_Cmd='c:/xxx/Ctags56'

linux user can use configure && make && make install to install it.

（2）使用
[/home/brimmer/src]$ ctags -R
"-R"表示递归创建，也就包括源代码根目录下的所有子目录下的源程序。"tags"文件中包括这些对象的列表：
l 用#define定义的宏
l 枚举型变量的值
l 函数的定义、原型和声明
l 名字空间（namespace）
l 类型定义（typedefs）
l 变量（包括定义和声明）
l 类（class）、结构（struct）、枚举类型（enum）和联合（union）
l 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，下面介绍一下定位这些对象的方法：

1) 用命令行。在运行vim的时候加上"-t"参数，例如：
[/home/brimmer/src]$ vim -t foo_bar
这个命令将打开定义"foo_bar"（变量或函数或其它）的文件，并把光标定位到这一行。
2) 在vim编辑器内用":ta"命令，例如：
:ta foo_bar
3) 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-]"。用"Ctrl-o"退回原来的地方。
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":set tags="命令设定"tags"文件的路径，这样vim才能找到"tags"文件。

在函数中移动光标
[{ 转到上一个位于第一列的"{"
}] 转到下一个位于第一列的"{"
{ 转到上一个空行
} 转到下一个空行（[ and ] 也分别是两个指令）
gd 转到当前光标所指的局部变量的定义
* 转到当前光标所指的单词下一次出现的地方
# 转到当前光标所指的单词上一次出现的地方
Vim 的创造者是一名计算机程序员，因此这就不奇怪 Vim 中有许多帮助编写程序的功能：
跳转到标识符被定义和使用的地方；在另一个窗口中预览有关的声明等等。
（ctags使用部分参考了文章“ctags和vim”，原文在
http://hi.baidu.com/original/blog/item/2cf8d53f00b7fcc27d1e71f0.html，
更多使用也请参考原文）

2. taglist
能够列出源文件中的tag(function, class, variable, etc)并跳转.
注意：taglist依赖于ctags，所以要先装ctags，否则taglist装了也没法用！
（1）到 http://vim.sourceforge.net/scripts/script.php?script_id=273
下载taglist_42.zip，即
http://vim.sourceforge.net/scripts/download_script.php?src_id=6416
（2）解压得到两个文件
# unzip -d taglist taglist_42.zip
# cd taglist
# tree
.
|-- doc
| `-- taglist.txt
`-- plugin
`-- taglist.vim
（3）安装
cp doc/taglist.txt /usr/share/vim/vim61/doc/
cp plugin/taglist.vim /usr/share/vim/vim61/plugin/
（4）配置和使用
cd /usr/share/vim/vim61/doc/
启动vim，用 “:helptags .”来配置好帮助文件
重启vim，用“:TlistToggle”来打开和关闭taglist窗口。
可以用“:help taglist”来获得更多帮助信
