浅谈Vim中的Tab与空格缩进

vim缩进参数解析

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

set tabstop=4
set softtabstop=4
set shiftwidth=4
set noexpandtab / expandtab1

解析：

tabstop

表示按一个tab之后，显示出来的相当于几个空格，默认的是8个。

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。

shiftwidth

表示每一级缩进的长度，一般设置成跟 softtabstop 一样

expandtab与noexpandtab

当设置成 expandtab 时，缩进用空格来表示，noexpandtab 则是用制表符表示一个缩进。个人习惯使用 ｀set expandtab｀

＃标志tab与空格

在vim中，默认情况下，没法区分空格和缩进，所以我们需要配置，使其能够区分。

我的配置如下

｀｀｀ 
set list↩ 
set listchars=tab:▸-,eol:↩︎,trail:-↩
