如何按右边框垂直对齐？

Question

考虑这个例子：

\hsize.1in \noindent \parfillskip=0pt \leftskip=0pt plus 1fil \hfuzz=2em hello world
\bye

结果是：

预期结果是：

为什么该示例没有产生预期的结果以及应如何修改？

Answer 1

段落拆分完成后，有两个溢出的框：“hello”和“world”。这些框被重新计算为示例中的宽度 .1in，并且由于 而未报告\hfuzz=2em。它们被放置在与 相同的位置\hfuzz=0pt。当然，溢出的框是正确重叠的。

如果你需要将段落中每个单词空间处的行折回，你可以尝试：

\hsize=0pt \noindent \parfillskip=0pt 
\leftskip=0pt plus 1fil minus10em            
hello world
\bye

这两种解决方案（您的和我的）的问题在于，结果的总宽度（最宽框的测量值）没有计算出来。因此，您需要将此结果右移，\moveright something\vbox{...}并且必须通过另一种方式计算（或估算）“某个”测量值。

如果您明确需要知道结果的宽度，那么您需要创建一个宏，将文本分成单词并测量最宽的单词。

Answer 2

以下代码利用\centering、\justify和flushright以相应的方式对齐文本。所提出的问题适合利用\begin{flushright} text \end{flushright}

\documentclass[12pt]{article}
\usepackage{ragged2e} %for use of \justify 

\begin{document}

Justified text:    
\justify

Flush right text:
\begin{flushright}
