colors - Modelica 网页颜色

问题描述

我认为将一些颜色定义为稍后在 Modelica 颜色注释中使用的常量可能会很方便。看起来 web 颜色是一个公认的标准，我将它们全部复制到一个常量数组包中：

但似乎我无法按预期使用它们，以下示例失败。似乎文字工作，或者如果我在同一个类中定义常量，但如果我导入它则不行。我做错了什么，还是我正在使用的工具的限制？

解决方案

原因很简单：图形注释取决于变量，仅当变量存在于结果文件中时才有效。因此，由于您的颜色注释正在使用导入调用数据，因此黄色代码不包含在结果文件中，因此您的测试框无法着色。相同的逻辑可以应用于受保护的变量：它将无法应用于任何图形注释。
