具有跟踪更改和换行功能的 URL

我正在尝试处理 URL，以便能够：

  • 如果 URL 太长超出页面宽度，则将其拆分为多行
  • 包括轨道变化模式，这意味着能够：
    • 删除线和下划线标记 URL 文本，以及
    • 改变文本颜色

为了做到这一点，我\bignumber{123456....}从 Michael Ummels 在将非常大的数字拆分成多行并对其进行了一些修改，以便我在 URL 文本中引入两个宏：\added{}和，\deleted{}它们控制跟踪更改模式的文本格式。这些宏依次使用宏\bignumber（\bignumberAdded{}和\bignumberDeleted{}）来确保跟踪更改模式中提供的文本也被拆分为多行。

这是代码，其中包括一系列示例来展示代码的作用。

在此处输入图片描述

到目前为止一切顺利，它似乎运行良好。现在的问题是，当我启动添加或删除的 url 文本时，它会给我一个非常奇怪的错误同一封信这很奇怪。换句话说，使用一个非常简单的示例，它可以工作：

%=========================================================
\begin{document}

\hrefMy{https://www.google.com/}{abcdef}

\hrefMy{https://www.google.com/}{\added{abcdef}}

\hrefMy{https://www.google.com/}{\deleted{abcdef}}

\end{document}

这也有效（请注意，字符串现在以两个连续的“a”开头）：

%=========================================================
\begin{document}

\hrefMy{https://www.google.com/}{aabcdef}

\end{document}

但这不起作用：

%=========================================================
\begin{document}

\hrefMy{https://www.google.com/}{\added{aabcdef}}

\hrefMy{https://www.google.com/}{\deleted{aabcdef}}

\end{document}

由于文本以“aa”开头，即两个连续的相同字符。Latex 给出了以下错误：

! Missing \endcsname inserted.
<to be read again>
\let
l.203 ...https://www.google.com/}{\added{aabcdef}}
The control sequence marked <to be read again> should
not appear between \csname and \endcsname.

有什么帮助吗？代码怎么可能不能处理具有两个连续相同字母的字符串？

谢谢！

PS 我无法使用其他宏作为 sloppypar、seqsplit 甚至通用函数，因为它们与我用于删除线（ ）和下划线（ ）\url{}的 soul 包不兼容。\st{}\ul{}

答案1

感谢 Ulrike 的提示，我找到了解决自己问题的方法。我在此处发布了更新后的代码，希望它对其他人有用。如果您测试后发现其他错误，请记下来！
