我正在使用 listings 包来设置当前项目中的代码片段样式，但遇到了一个我无法理解的问题。我使用的编程语言是 SCL（PLC 编程语言），您可以像这样处理 PLC 的输入和输出： %IX0.2。然后，我使用的 IDE 将 % 及其后的地址涂成紫色。我想在我的 latex 项目中做同样的事情，但不知道该如何处理。我已经尝试过使用该morecomment=[s]{}{}选项，但它只接受非空白字符作为分隔符的输入……
有人知道我该如何实现这个目标吗？
这是我的代码的一个最小工作示例：

在 Windows 10 上使用 MiKTeX 22.7 进行了测试

我建议使用，从中morecomment=[s][\color{purple}]{\%}{\ }删除，并使用将其转换为字母。.otherkeywords.alsoletter={.}
我会完全删除你的morekeywords因为该选项只对文字有效没有类别 的 特征other.
