仅针对前导空格通过列表字符显示“空格"字符 [英] Show 'space' character via listchars only for leading spaces

问题描述

是否可以在 Vim 中使用我的编辑器(编辑 .c 和 .h 文件时)，通过 listchars 显示，一个特殊的字符仅用于前导空格字符?

Is it possible in Vim to have my editor (when editing .c and .h files), show via listchars, a special character only for leading space characters?

我发现一个单独的帖子指出，从 7.4 版开始，Vim 现在支持通过 listchars 突出显示所有空格字符.这是我当前的 listchars 变量:

I found a separate post that noted, as of version 7.4, Vim now supports highlighting all space characters via listchars. Here's my current listchars variable:

set list listchars=tab:>-,trail:.,extends:>,precedes:<,space:.

这是它在我的屏幕上的显示效果:

And here is a render of how it appears on my screen:

但是，我希望它看起来像这样(如下)，其中只有 leading 空格通过 listchars 呈现，并且缩进相关空格之后出现的空格不是呈现.即:

However, I would like it to appear like so (below), where only leading spaces are rendered via listchars, and spaces occurring after indentation-related spaces are not rendered. ie:

是否有一种简单的方法可以通过配色方案或 .vimrc 更改来实现此目的?

Is there a simple way to accomplish this, either via color scheme or .vimrc changes?

图像差异，以防由于低对比度而导致差异不明显:

推荐答案

我认为 linechars 不会帮助你，但这个亮点可能会有所帮助:

I don't think that linechars will help you, but this highlight might help:

highlight WhiteSpaceBol guibg=lightgreen
match WhiteSpaceBol /^ \+/

更改您最喜欢的配色方案.

Change the color scheme for whatever you like best.

如果你坚持要花哨的·，你可以通过一些技巧来获得它们:

If you insist on having the fancy · you can get them with a bit of a hack:

set listchars=space:·
highlight WhiteSpaceBol guifg=blue
highlight WhiteSpaceMol guifg=white
match WhiteSpaceMol / /
2match WhiteSpaceBol /^ \+/

现在，只有起始的 · 是可见的！(将 white 更改为您用作背景的任何颜色，将 blue 更改为您选择的颜色).

Now, only the starting · are visible! (change the white for whatever color you use as background and blue with the color of your choice).

注意:如果您使用控制台 Vim，请将 guibg 替换(或添加)为 ctermbg 和适当的颜色.

NOTE: If you use the console Vim, replace (or add) guibg with ctermbg and the proper colors.
