vim+Vundle+vim-autoformat+astyle格式化代码

Vundle是vim插件管理工具，用来管理vim插件，vim-autoformat是代码格式化插件

1.安装Vundle（参考点击打开链接）

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

2.在.vimrc文件中添加如下内容

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'

Plugin 'Chiel92/vim-autoformat'

" All of your Plugins must be added before the following linecall vundle#end() " requiredfiletype 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

3.重启vim，在vim中执行:PluginInstall，安装vim-autoformat

4.安装 astyle

sudo apt-get install astyle

也可以安装其他语言对应的格式化插件，安装完成后，会执行默认格式化设置

5.自定义astyle格式化，在.vimrc中添加如下代码

let g:formatdef_my_cpp = '"astyle --style=google"'
let g:formatters_cpp = ['my_cpp']
au BufWrite * :Autoformat

代码保存时，会自动进行格式化
