linux vim(nvim)c++代码格式化工具clang-format

1. 安装vim-clang-format插件
   项目地址：vim-clang-format
   如果用Plug管理vim插件，直接在.vimrc中添加一行
   Plug ‘rhysd/vim-clang-format’
   运行:PlugInstall就可以自动安装插件

2. 配置
   支持的语言
   C
   C++
   Objective-C
   JavaScript
   java
   TypeScript
   Protobuf

" map to cf in C++ code
autocmd FileType h,cc,c,cpp,objc nnoremap cf :ClangFormat
autocmd FileType h,cc,c,cpp,objc vnoremap cf :ClangFormat
" let g:clang_format#auto_format_on_insert_leave=1	"退出插入模式时自动格式化

3. 安装clang-format:
   npm install -g clang-format
4. 格式化方式
   可以创建一个文件.clang-format放到根目录
   可以参考： https://www.cnblogs.com/lepeCoder/p/8032178.html
