c++ - KDevelop 4.2.2 语法高亮问题

Question

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 - 我该如何改变它？我希望我的所有变量都是浅蓝色的。

2）功能颜色总是紫色，我该如何改变？

如果有人知道答案，我将不胜感激。

谢谢！！

Answer 1

你的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。去

设置 -> 配置 KDevelop... -> 语言支持

并确保在Semantic Code Highlighting零件中两者Local Colorization Intensity都Global Colorization Intensity设置为零（即向左滑动滑块）。

然而，你为什么要这个？就个人而言，我发现为每个变量设置不同的颜色非常方便。它使您可以非常轻松地发现特定变量的所有出现。

Answer 2

是的...源代码非常“差”...有许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......所以我给 kdevplatform 做了这个补丁：

它删除了生成的颜色，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）。

在 Archlinux 上我也做了这个 PKGBUILD ：

Answer 3

不要摆脱不同颜色的变量，你会问自己过去没有它你是怎么做的。
