如何让灵魂驱动器同时绘制两条线（一条在文本上方，一条在文本下方）

这是来自带圆角的文本框突出显示（基于灵魂）期望的最终结果是一种“带圆圈的文本”，就像用铅笔注释文本一样。

我自己回答了这个问题，基于 Antal Spector-Zabusky 的方法LaTeX 中的酷炫文本突出显示。结果很酷，但有一个重要的限制是它不允许分页。它不允许，因为该方法依赖于soul提供坐标并让我们tikz完成所有绘图。Antal 的答案需要这样做，因为路径所需的不规则性（在绘图中有意义）取决于来自的装饰tikz。

好吧，我正在寻找“不那么酷”的东西，并且对文本上方和下方的直线感到满意。为此，我可以依靠soul而不是tikz绘制它们，从而保留分页功能。然后，tikz仅用于绘制角落。

soul我最初的想法是相同的，但基于的驱动程序从头开始尝试\ul。下面的代码很接近，但不完全一样。我无法说服自己\SOUL@everyspace也画出上面的线。

问题的关键似乎在于：

\def\SOUL@tceveryspace#1{%
  \SOUL@ulcolor{
    #1%
    \SOUL@tcleaders
    \hskip\spaceskip
  }%
  \null
}

\SOUL@tcleaders实际绘图在哪里\hrule：

\def\SOUL@tcleaders{%
  \leaders\hrule\@depth\SOUL@tcdp\@height\SOUL@tcht\relax
}

有没有办法hrules在这一步绘制两者（底部和顶部）？

也就是说，除了空格上方的线条外，其他一切都已就位。有什么想法可以实现它们吗？

答案1

您已经完成了所有工作。我只是做了一些改动\SOUL@tceveryspace（说实话，我根本没有阅读其余的代码）。该命令本质上使用了\leaders\hrule\hskip\spaceskip，这意味着“制作一条水平线，其行为类似于长度为 的胶水\spaceskip。特别是，胶水允许换行，并且在换行时会被删除（就像普通空格一样）。为了在上方和下方都有线条，我只需使用一个引线、一个负空间以返回原始位置并在顶部使用另一个引线。您可以看到，在我的第一个线条之后，所有内容都正确拉伸了\begin{document}。
