Latex：用向后箭头替换连字符

发布于 2024-10-12 21:40:12 字数 459 浏览 2 评论 0原文

我正在以打字机字体设置例如目录名称。这些名称可能会变长。使用 hyphenat 包，我启用了连字符。现在，缺少的是连字符被替换为例如向后箭头。因此，我想做的是

\usepackage[htt]{hyphenat}
\newcommand{\origttfamily}{}%
\let\origttfamily=\ttfamily%
\renewcommand{\ttfamily}{\origttfamily \hyphenchar\font=\ensuremath{\hookleftarrow}}
\begin{document}
\texttt{/etc/really/long{\fshyp}directory{\fshyp}name/}
\end{document}

， \ensuremath{\hookleftarrow} 在这种情况下不起作用 - 它不是单个字符。

有人可以指出我的解决方案吗？多谢！

原文

I am setting e.g. directory names in a typewriter font. These names can become long. With the hyphenat package, I enabled hyphenation.
Now, what is missing, is that the hyphenation character is replaced e.g. by a backwards oriented arrow.
Thus, what I want to do is something like

\usepackage[htt]{hyphenat}
\newcommand{\origttfamily}{}%
\let\origttfamily=\ttfamily%
\renewcommand{\ttfamily}{\origttfamily \hyphenchar\font=\ensuremath{\hookleftarrow}}
\begin{document}
\texttt{/etc/really/long{\fshyp}directory{\fshyp}name/}
\end{document}

however, \ensuremath{\hookleftarrow} does not work in this case - it is not a single character.

Can somebody point me towards a solution? Thanks a lot!

您无法将 \hyphenchar 设置为其他字体的字符，但可以重新定义 \BreakableSlash：

\documentclass{minimal}
\usepackage[htt]{hyphenat}
\newsavebox\leftarrowbox
\sbox\leftarrowbox{$\leftarrow$}
\makeatletter
\renewcommand*{\BreakableSlash}{%
  \leavevmode
  \prw@zbreak
  /%
  \discretionary{\usebox\leftarrowbox}{}{}%
  \prw@zbreak
}
\makeatother
\begin{document}
\parbox{20mm}{%
  \texttt{/etc\fshyp really\fshyp long\fshyp directory\fshyp name/}%
}
\end{document}

You cannot set the \hyphenchar to a character from a different font, but you can redefine \BreakableSlash:

\documentclass{minimal}
\usepackage[htt]{hyphenat}
\newsavebox\leftarrowbox
\sbox\leftarrowbox{$\leftarrow$}
\makeatletter
\renewcommand*{\BreakableSlash}{%
  \leavevmode
  \prw@zbreak
  /%
  \discretionary{\usebox\leftarrowbox}{}{}%
  \prw@zbreak
}
\makeatother
\begin{document}
\parbox{20mm}{%
  \texttt{/etc\fshyp really\fshyp long\fshyp directory\fshyp name/}%
}
\end{document}
