配置文件

vim的配置是在用户主目录下的 ~/.vimrc 文件中完成的，如果没有的话，需要自己新建一下：

1
2
cd ~
touch .vimrc

安装Vundle

Vundle 是 Vim bundle 的简称,使用git来管理vim插件，有了它，安装其它插件就方便很多。
项目地址:https://github.com/VundleVim/Vundle.vim
首先下载源码：

1
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

如果~/.vim/bundle目录不存在，则新建目录：

1
2
3
4
cd ~
mkdir .vim
cd .vim
mkdir bundle

然后将下列配置放在.vimrc文件的开头：

1

12

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()
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
" All of your Plugins must be added before the following line
call vundle#end()            " required
filetype plugin indent on    " required

如果想下载某个插件，比如自动缩进indentpython.vim插件，需要将

1
Plugin 'vim-scripts/indentpython.vim'

置于call vundle#begin()和call vundle#end()之间，保存配置后在vim中执行

1
:PluginInstall

即可以自动下载indentpython.vim插件了。
bundle可以管理下载几种不同的插件,方式如下：

github上的插件
Plugin 'tpope/vim-fugitive'
来自于http://vim-scripts.org/vim/scripts.html的插件
Plugin 'L9'
非github上的git插件
Plugin 'git://git.wincent.com/command-t.git'
本地插件
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/'}
有旧插件的情况下，下载新的插件并重命名以避免冲突
Plugin 'ascenator/L9', {'name': 'newL9'}

下载方式除了在vim中运行:PluginInstall外，还可以在命令行中运行：

1
vim +PluginInstall +qall

其它常用的命令：

1
2
3
4
: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
