给vim增加Vundle和NERDTree插件

先给vim加了两个插件。

windows下的插件应该放在/Users/用户名/.vim目录下。

然后clone一下vundle。

cd %USERPROFILE%
git clone https://github.com/gmarik/Vundle.vim.git %USERPROFILE%/.vim/bundle/Vundle.vim

编辑_vimrc。

" 设置含有并且初始化Vundle的运行环境
set rtp+=~/.vim/bundle/vundle.vim/
call vundle#begin()

Plugin 'vundle.vim'
Plugin 'nerdtree'

call vundle#end()            " required
filetype plugin indent on    " required

set autochdir
let mapleader=","
let NERDTreeChDirMode=2
nnoremap file :NERDTree .

装NERDTree的时候也一样，放在同一个目录下。
这里有一个问题，理论上来说打开NERDTree的时候应该是当前目录，而我无论怎么开都是C:\System。

所以在_vimrc中加入

set autochdir
let mapleader=","
let NERDTreeChDirMode=2
nnoremap file :NERDTree .

每次在normal模式下键入,file就能打开当前目录下的树了。
