VIM:在窗口左侧显示3个字符的边框

Question

上下文

我正在使用NERDTree插件.

让我烦恼的一件事是NERDTree本身和我的代码之间的视觉垂直边界.我发现阅读我的代码有点烦人.我目前的设置看起来像:

........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________
........................#________________________________________________

其中... = NERDTree,_ =我的实际代码,### =一些垂直灰色边框.

现在,我想要的是这样的:

........................#   ________________________________________________
........................#   ________________________________________________
........................#   ________________________________________________
........................#   ________________________________________________
........................#   ________________________________________________
........................#   ________________________________________________
........................#   ________________________________________________
........................#   ________________________________________________
........................#   ________________________________________________
........................#   ________________________________________________

我的想法是,我以某种方式在NERDTre的垂直分隔符和我的实际代码的左边注入一个3个字符的边框.

现在,我几乎可以通过"set nu"实现这一点 - 除了获得空格,我得到了一堆数字.我想要像"set nub"这样的东西,除了代替行号,我只是得到空格.

题:

我如何实现上述目标？

您可以用来foldcolumn创建排水沟：

:set foldcolumn=3

如果这会向装订线添加折叠标记并且您根本不使用折叠，那么您可以设置foldmethod为manual不自动创建折叠：

:set foldmethod=manual
