命令之后、句号之前换行

Question

这是输出pdflatex：

相关的 LaTeX 行是：

You can similarly enable the third and fourth channel by giving \texttt{HIGH} input to \icpin{9}{EN3,4}.

以下是我定义\icpin命令的方式：

\newcommand{\icpin}[2]{\setlength{\fboxsep}{0pt} \fbox{\texttt{\colorbox{lgray}{\strut{}\,PIN~#1\,}\,#2\,}} \setlength{\fboxsep}{2pt}}

我猜问题出在我定义的命令上。如何强制换行符不在句点之前出现？

我尝试\@在期限后使用，但问题并未解决。

Answer 1

您给出的定义有两个空格，您应该删除它们

\newcommand{\icpin}[2]{\setlength{\fboxsep}{0pt} \fbox{\texttt{\colorbox{lgray}{\strut{}\,PIN~#1\,}\,#2\,}} \setlength{\fboxsep}{2pt}}
                                                ^                                                          ^

以下是正确格式的，但有一些变化：

\newcommand{\icpin}[2]{%
  \begingroup
  \setlength{\fboxsep}{0pt}%
  \fbox{%
    \ttfamily
    \colorbox{lgray}{\strut\,PIN~#1\,}\,#2\,%
  }%
  \endgroup
}

该组将设置设为\fboxsep本地设置，因此您无需明确重置它。使用\ttfamily可避免使用另一对括号：该组将限制此声明的效果。

完整代码：

\documentclass{article}
\usepackage{xcolor}

\definecolor{lgray}{gray}{0.7}

\newcommand{\icpin}[2]{%
  \begingroup
  \setlength{\fboxsep}{0pt}%
  \fbox{%
    \ttfamily
    \colorbox{lgray}{\strut\,PIN~#1\,}\,#2\,%
  }%
  \endgroup
}

\begin{document}

You can similarly enable the third and fourth channel
by giving \texttt{HIGH} input to \icpin{9}{EN3,4}.

\end{document}

也许您还应该在两端添加一些细小的空间。

\documentclass{article}
\usepackage{xcolor}

\definecolor{lgray}{gray}{0.7}

\newcommand{\icpin}[2]{%
  \begingroup
  \setlength{\fboxsep}{0pt}%
  \leavevmode\,% <-- don't forget \leavevmode
  \fbox{%
    \ttfamily
    \colorbox{lgray}{\strut\,PIN~#1\,}\,#2\,%
  }%
  \,%
  \endgroup
}

\begin{document}

You can similarly enable the third and fourth channel
by giving \texttt{HIGH} input to \icpin{9}{EN3,4}.

\end{document}

Answer 2

删除\,和多余的空格似乎使句号附加到框上。这是一个之前和后图像：

代码：

\documentclass{article}
\usepackage{xcolor}

\newcommand{\icpin}[2]{%
    \setlength{\fboxsep}{0pt}%
    \fbox{\texttt{\colorbox{gray}{\strut{}\,PIN~#1\,}\,#2}}%
    \setlength{\fboxsep}{2pt}%
}%

\begin{document}
You can similarly enable the third and fourth channel by giving \texttt{HIGH} input to \icpin{9}{EN3,4}.

\end{document}
