Vim，是从vi发展出来的一个文本编辑器，终端下文本编辑利器。vim缺乏默认插件管理，在使用插件时，插件文件散布在~/.vim目录下，插件管理非常麻烦，很容易出错。今天就来介绍一款vim插件管理器：Vundle。
GitHub开源库：https://github.com/VundleVim/Vundle.vim
安装
使用git方式安装：
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
clone 完成后，打开~/.vimrc配置，增加如下内容，启用Vundle插件管理：
set nocompatible " be iMproved, required
filetype off " required
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
" The following are examples of different formats supported.
" Keep Plugin commands between vundle#begin/end.
" plugin on GitHub repo
Plugin 'tpope/vim-fugitive'
" plugin from http://vim-scripts.org/vim/scripts.html
" Plugin 'L9'
" Git plugin not hosted on GitHub
Plugin 'git://git.wincent.com/command-t.git'
" git repos on your local machine (i.e. when working on your own plugin)
Plugin 'file:///home/gmarik/path/to/plugin'
" The sparkup vim script is in a subdirectory of this repo called vim.
" Pass the path to set the runtimepath properly.
Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}
" Install L9 and avoid a Naming conflict if you've already installed a
" different version somewhere else.
" Plugin 'ascenator/L9', {'name': 'newL9'}
" All of your Plugins must be added before the following line
call vundle#end() " required
filetype plugin indent on " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" :PluginList - lists configured plugins
" :PluginInstall - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line

运行vim，输入:PluginInstall 完成第一次初始化安装。
插件安装
插件安装有两种方式：
1.修改vimrc，编辑~/.vimrc，把要安装的插件以Plugin 'xxx/xxx' 的格式添加到" call vundle#begin('~/some/path/here') 和 call vundle#end() " required 之间，保存关闭。打开vim，执行:PluginInstall即可。
2.使用命令行vim +PluginInstall +qall
其他常用命令
更新插件 :BundleUpdate
列出所有插件 :BundleList
查找插件 :BundleSearch

一些问题
1.vim开启行数显示和语法高亮，在iTerm2下显示诡异：

修改iTerm2 的 Report terminal type 为 xterm-256color 可以解决。
