Question

我使用vim（安装在cygwin上）来编写c++个程序，但它没有突出显示c++个new个关键字，delete }}，public，friend，try，但要突出显示其他内容，例如namespace，int，const，operator， true，class，include。它也不会改变运营商的颜色。

我从未更改过它的语法文件。它出什么问题了？非常感谢。

我使用自定义配色方案;当我将其更改为desert配色方案时，突出显示没有问题，但我需要使用该配色方案，并且无法将其更改为其他颜色方案。

我希望它显示程序如下图所示（我在图片中使用了带有notepad ++的配色方案）：

example of correctly colored one

但现在如下图所示： not correctly colored one

colorscheme在这里：

Answer 1

将此添加到C突出显示段落：

call <SID>X("Statement", s:purple, "", "")

Answer 2

您提到的所有关键字最终都会链接到标准Statement语法组。也许那个被清除了。尝试

:verbose highlight Statement

如果显示xxx cleared，则更进一步，现在需要调查为什么你的colorscheme没有定义着色。

vim没有突出显示一些c ++关键字
