带有圆角的彩色背景，用于防止文本片段溢出行尾

我已经找到了一些类似的解决方案，但无法使它们适应我的要求：

  • 被其他文本包围的文本片段（例如源代码）应使用背景色突出显示。背景应有略圆的角。背景有边框是不错的选择，但不是必需的。
  • 我们可以假设文本片段的长度不会超过一整行。但是，文本片段可能不适合当前行的剩余宽度。我​​希望找到以下解决方案之一来解决这个问题：
    1. 与往常一样，文本片段不合适的部分将换到下一行（期望的输出示例：如下方第一张图所示，但带有圆角）。
    2. LaTeX 确定文本片段不适合当前行，并自动将整个文本片段放在下一行。看起来不太好看，因为它不再完全对齐，但还可以。（期望的输出示例：如下面的第二幅图所示，但带有圆角）。

相关解决方案：

使用第一个链接中的建议（通过灵魂或通过复杂解决方案）我可以得到这个输出。它几乎完美，但没有圆角。这个问题告诉我使用灵魂可能无法实现。有没有什么方法可以修改其他解决方案？ 在此处输入图片描述

与第三个链接中的解决方案相结合soul可行，但也没有圆角（\lword在第三个链接中定义）：

\newcommand{\inlinecode}[1]{{\lword{\sethlcolor{veryLightGray}\hl{\small\ttfamily#1}}}}

这是一个答案，通过结合使用椭圆突出显示和换行符圆角代码和灵魂突破。

编辑：添加了不在换行符周围四舍五入突出显示的逻辑。
