vim常用配置

配置文件地址为/etc/vimrc

或者可以在Home文件夹下自建.vimrc

set number
显示行号

set autoindent
换行后自动缩进

set smartindent
输入花括号换行后自动缩进

set tabstop=4
Tab键位4个空格

set shiftwidth=4
自动缩进的值为4个空格

set expandtab
只用空格代替Tab。（这个功能对Python或者Haskell这种对缩进和空格很敏感的编程语言很重要。）

Alternatively, you can copy the following content into your .vimrc file.
