如何在命令中不使用连字符？

Question

我有一个要求，即某些单词应该在正文中单独格式化。为此，我编写了一个新命令

\newcommand{\concept}[1]{\textcolor{gray}{\texttt{#1}}}

我不希望命令中写入的单词\concept{}被连字符连接。它们可以推到下一行，但不能被连字符连接。我在这里有什么选择？

编辑 1：在 MWE 中添加了显示连字符的包\texttt。我不需要在一段话中写那么多条目，只需显示它是如何破坏内部tt环境的。使用 进行编译xelatex。

Answer 1

您应该声明等宽字体的文本不应该使用连字符，fontspec默认情况下不会这样做：

\documentclass[12pt,a4paper]{article}
\usepackage{geometry}
\geometry{
  a4paper,
  textwidth=6.in,
  textheight=9.25in,
  marginparsep=7pt,
  marginparwidth=.6in
}
\usepackage[svgnames]{xcolor}
\usepackage{libertine}

\setmonofont{Latin Modern Mono Light}[HyphenChar=None]

\renewcommand{\baselinestretch}{1.3}
\newcommand{\concept}[1]{\textcolor{gray}{\texttt{(#1)}}}

\begin{document}

Each step in the development of the \concept{bourgeoisie} was accompanied 
by a corresponding \concept{political} advance of that class. An 
\concept{oppressed} class under the sway of the feudal nobility, an armed 
and self-governing association in the \concept{medieval} \concept{commune}: 
here independent urban republic (as in Italy and Germany); there taxable 
“third estate” of the \concept{monarchy} (as in France); afterwards, in the 
period of manufacturing proper, serving either the \concept{semi-feudal} or 
the absolute monarchy as a counterpoise against the \concept{nobility}, and, 
in fact, cornerstone of the great monarchies in general, the 
\concept{bourgeoisie} has at last, since the establishment of Modern Industry 
and of the world market, conquered for itself, in the \concept{modern}
representative \concept{State}, exclusive political sway. The executive of
the modern state is but a committee for managing the common affairs of the
whole bourgeoisie.

但是，这会导致许多行过满；此类段落应排版为\sloppy；使用sloppypar来限制行为。使用microtype可减少丑陋。

Answer 2

如果texttt文本仍然带连字符（即使不应该带连字符）或者当您有类似的任务时，您可以尝试mbox它，即：

 \newcommand{\concept}[1]{\mbox{\textcolor{gray}{\texttt{#1}}}}

一个小例子：

\documentclass{article}
\usepackage{xcolor}
\newcommand{\concept}[1]{\mbox{\textcolor{gray}{\texttt{#1}}}}
\begin{document}
A pre-test question about how to find distance from the Earth to the Sun \concept{(collaboration)}\concept{(prior knowledge)}
\end{document}

结果
