对于我的 C++ 开发，我在 Ubuntu Natty 上运行 KDevelop，我有两个问题：
1) 它以随机彩虹色突出显示我的所有变量 - 我该如何更改？我希望我的所有变量都是浅蓝色的。
2) 函数颜色总是紫色，我该如何更改？
如果有人知道答案，我将不胜感激。
谢谢！！
【问题讨论】：
这两个问题的答案很简单：目前你不能。
您可以确保所有变量都以相同的颜色突出显示，但该颜色将为黑色且无法更改。前往
设置 -> 配置 KDevelop... -> 语言支持
并确保在Semantic Code Highlighting 部分中，Local Colorization Intensity 和 Global Colorization Intensity 都设置为零（即向左滑动滑块）。
但是，您为什么想要这个？就个人而言，我发现为每个变量设置不同的颜色非常方便。它可以让您非常轻松地发现特定变量的所有出现。
【讨论】：
是的...源代码很“差”...有很多硬编码值没有选项可以更改它们...幸运的是，它是开源的；）
我遇到了同样的问题：我同意，彩虹色在某些方面增加了可读性，但就个人而言，它分散了我的注意力......所以我为 kdevplatform 做了这个补丁：

它会移除生成的颜色，因此变量现在是真正的黑色（前景色）。
对于 2)，当前版本似乎尊重 kate 语法颜色（不确定）。

【讨论】：
不要去掉不同颜色的变量，你会问自己过去没有它你是怎么做的。
