vim set fileformat 执行 set fileformat 会返回当前文件的 format 类型 如:fileformat=dos 也可执行 set line
ts 是tabstop的缩写,设TAB宽度为4个空格。
softtabstop 表示在编辑模式的时候按退格键的时候退回缩进的长度,当使用 expandtab 时特别有用。
shiftwidth 表示每一级缩进的长度,一般设置成跟 softtabstop 一样。
expandtab表示缩进用空格来表示,noexpandtab 则是用制表符表示一个缩进。
autoindent自动缩进
空格|tab 长度设置
set ts=4 set softtabstop=4 set shiftwidth=4 set expandtab set autoindent
上面配置可以添加到 vim 配置文件中:/etc/virc 和 /etc/vimrc
TAB替换为空格
:set ts=4 :set expandtab :%retab!
空格替换为TAB
:set ts=4 :set noexpandtab :%retab!
