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:-↩
