如何让vim不缩进前导空格？

问题描述 投票：0回答：1

我希望 vim 仅使用制表符缩进，但使用 

=
总是在一系列制表符后给我一个前导 2 个空格。

我尝试了很多方法，包括这里的所有内容如何在vim中仅使用制表符（而不是空格）。我有 

autoindent noexpandtab tabstop=8 shiftwidth=8 copyindent preserveindent softtabstop=0
，但是在 vim 中应用 
=
仍然给我 2 的前导空格。我尝试查看加载的文件类型插件，但无法调试问题。

为什么会发生这种情况，我该如何解决？

（编辑：我注意到即使使用

vim -u NONE
也会发生这种情况）

（编辑：补充信息）

我的

indentexpr
和
equalprg
都设置为空。主要是，我正在编辑 Javascript 文件，通过 
debug
和 
breakadd file *.vim
，我可以看到 vim 加载 
.../share/vim/vim90/syntax/javascript.vim
并包含以下内容：

（转自评论）

我想我已经解决了部分问题。

即使我设置了

nocindent
，并且所有缩进设置（如
indentexpr
）都是空的，我的症状可能就像正在应用
cindent
一样。我的前导空格会在某些情况下出现，包括每当我用未闭合的括号继续一行，或者有带有前导逗号的新行时。

虽然在阅读手册后我仍然不确定 cindent 的哪一部分会给我前导空格https://vimhelp.org/indent.txt.html#cinoptions-values，通过实验，我发现设置任何 

indextexpr
都将不再表现出该行为。

现在我求助于 

set indentexpr=(cindent(v:lnum)/8)*8
来强制发生的任何 
cindent
在选项卡上对齐。
