简述Vim中Tab与空格缩进

缩进用 tab 制表符还是空格，个人爱好问题。但是在大多项目中，习惯使用空格。关于缩进，vim中可以通过如下四个参数进行配置。

et tabstop=4
set softtabstop=4
set shift required! /** 从这行开始，vimrc配置 **/
filetype plugin indent on
"autocmd FileType php set omnifunc=phpcomplete#CompletePHP
" 让配置变更立即生效
set backspace=indent,eol,start

set fileencodings=utf-8,ucs-bom,gb18030,gbk,gb2312,cp936

set smartindent " 打开智能缩进
set smarttab
set showmatch " 设置括号匹配
" 开启实时搜索功能
