当且仅当 \savebox 内没有空间时，将右对齐的文本移至下一行

tag-icon • tag-icon spacing horizontal-alignment boxes
当且仅当 \savebox 内没有空间时，将右对齐的文本移至下一行

这是我之前问题的后续如果没有空间，则将右对齐的文本移至下一行。现在的区别是我需要将此格式化的文本放置在 内\savebox。在我的实际用例中，出于性能原因，我正在缓存需要跟随现有文本（即在同一行）的文本，并且此缓存的文本包含一些要与页面边缘右对齐的文本。

我尝试使用所有四种解决方案如果没有空间，则将右对齐的文本移至下一行以及一个简单的\hfill。这些在 之外使用时似乎都可以工作\savebox，但在 内部使用时则不行\savebox：

笔记：

  • 我可以不是使用\parbox{\linewidth}{}，因为我不知道从哪一行\savebox开始。也就是说，同一行上有文本前已\usebox应用。
  • 所需版本将与文本XXX一样在右侧对齐ZZZ。

\parbox使用宽度为的选项linegoal由linegoal包裹：
