texttt 中的换行符，与数学模式下的 textttt 配合使用

Question

我希望有自动换行符\texttt（特别是对于我的情况，在文本模式下），同时\texttt在数学模式下不会导致构建错误。添加连字符或使用\path或\url并不美观，因为最好显示文本 0xcf416c536ec1a19ed1fb89e4ec7ffb3cf73aa413b3aa9b77d60e4fd81a4296ba，没有任何连字符或其他会中断它的字符，也没有 URL 边框，此外，能够双击文本进行复制和粘贴也很好。

This is more filler text. This is more filler text. This is more filler text,   \texttt{0xcf416c536ec1a19ed1fb89e4ec7ffb3cf73aa413b3aa9b77d60e4fd81a4296ba},

我尝试过以下解决方案文本中的换行符。如果我尝试其中任何一个答案，我都会得到以下错误。上面的 MWE 取自https://tex.stackexchange.com/a/219454/143781，我得到：

! LaTeX Error: Command \ttfamily invalid in math mode.

Answer 1

我不确定你为什么要重载\texttt，但以下是有效的。

\documentclass[9pt,oneside]{amsart}
\usepackage{letltxmacro}

\begingroup
  \catcode`\.=\active
  \gdef.{\normalperiod\allowbreak}%
\endgroup

\DeclareRobustCommand\aepath[1]{%%
  \bgroup 
    \let\normalperiod=.%%
    \catcode`\.=\active
    \everyeof{\noexpand}%%
    \endlinechar=-1%%
    \oldtexttt{\scantokens{#1}}%%
  \egroup
}

\LetLtxMacro\oldtexttt\texttt
\let\texttt\aepath

\begin{document}

filler text $\texttt{KEC}$ 

This is more filler text,  \texttt{0xcf416c536ec1a19ed1fb89e4ec7ffb3cf73aa413b3aa9b77d60e4fd81a4296ba},

以下是如何自动拆分长序列的方法。我还添加了相同的方法\seqsplit。使用新\aepath宏，您可以决定在多少个字符后可以中断，而 的实现\seqsplit不允许这样做。

\documentclass[9pt,oneside]{amsart}
\usepackage{xparse}
\usepackage{seqsplit}

\ExplSyntaxOn
\NewDocumentCommand\aepath{O{4}m}
 {
  \texttt{ \ray_aepath:nn { #1 } { #2 } }
 }

\cs_new:Nn \ray_aepath:nn
 {
  \tl_range:nnn { #2 } { 1 } { #1 }
  \tl_map_function:fN
   { \tl_range:nnn { #2 } { #1+1 } { \tl_count:n { #2 } } }
   \ray_aepath_addbreak:n
 }
\cs_generate_variant:Nn \tl_map_function:nN { f }
\cs_new:Nn \ray_aepath_addbreak:n
 {
  \hspace{0pt plus 0.2pt} #1
 }
\ExplSyntaxOff

\begin{document}

This is more filler text,
\aepath{0xcf416c536ec1a19ed1fb89e4ec7ffb3cf73aa413b3aa9b77d60e4fd81a4296ba},

\begin{minipage}[t]{4.5cm}
This is more filler text,
\aepath{0xcf416c536ec1a19ed1fb89e4ec7ffb3cf73aa413b3aa9b77d60e4fd81a4296ba},
\end{minipage}\qquad
\begin{minipage}[t]{0pt}\hfuzz=\maxdimen % no overfull
\aepath{0xcf416c5},
\end{minipage}\qquad\qquad
\begin{minipage}[t]{0pt}\hfuzz=\maxdimen % no overfull
\aepath[1]{0xcf416c5},
\end{minipage}

\bigskip\bigskip

\begin{minipage}[t]{4.5cm}
This is more filler text,
\texttt{\seqsplit{0xcf416c536ec1a19ed1fb89e4ec7ffb3cf73aa413b3aa9b77d60e4fd81a4296ba}},
\end{minipage}\qquad
\begin{minipage}[t]{0pt}\hfuzz=\maxdimen % no overfull
\texttt{\seqsplit{0xcf416c5}},
\end{minipage}\qquad\qquad
\begin{minipage}[t]{0pt}\hfuzz=\maxdimen % no overfull

Answer 2

您可以\mathtt在数学模式中使用：

\documentclass[9pt,oneside]{amsart}

\begingroup
\catcode`\.=\active
\gdef.{\normalperiod\allowbreak}%
\endgroup

\newcommand\aepath[1]{%%
    \bgroup 
    \let\normalperiod=.%%
    \catcode`\.=\active
    \everyeof{\noexpand}%%
    \endlinechar=-1%%
    \ttfamily\scantokens{#1}%%
    \egroup}

\let\oldtexttt\texttt
\let\texttt\aepath
\begin{document}

    filler text $\mathtt{KEC}$ 

    This is more filler text,  \texttt{0xcf416c536ec1a19ed1fb89e4ec7ffb3cf73aa413b3aa9b77d60e4fd81a4296ba}, 

\end{document}

Answer 3

使用 \seqsplit。

\documentclass[9pt,oneside]{amsart}

\usepackage{seqsplit}

\begin{document}

Filler text. Filler text. Filler text. Filler text. \seqsplit{0xcf416c536ec1a19ed1fb89e4ec7ffb3cf73aa413b3aa9b77d60e4fd81a4296ba}

\end{document}
