如何缩进和悬挂缩进

Question

我在缩进方面遇到了麻烦。我希望一个非缩进的段落后面跟着一个缩进的多行示例。该示例应该有一个悬挂缩进。我试过使用该hanging包，但没有成功。这是一个 MWE：

\documentclass[letterpaper,12pt,titlepage,openright,twoside,final]{book}

\begin{document}

\noindent Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. \\

{\textbf{Example}}: Suppose this is an example. I would like the example to be indented (yay, it is!), and I would like the text on the next line of the example to line up with the letter ``S" in ``Suppose" at the beginning of the first sentence in the example. \\

\noindent Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph.
\end{document}

Answer 1

您可以使用description列表：

\begin{description}[leftmargin=!,labelwidth=\widthof{\bfseries Example:}]
  \item [Example:] Suppose this is an example. I would like ... 
\end{description}

如果你还想缩进整个例子块，您可以使用labelindent。例如，

\begin{description}[leftmargin=!,labelwidth=\widthof{\bfseries Example:},labelindent=2.0em]
  \item [Example:] Suppose this is an example. I would like ... 
\end{description}

你得到：

代码：

\documentclass[letterpaper,12pt,titlepage,openright,twoside,final]{book}

\usepackage{enumitem}
\usepackage{calc}

\begin{document}

\noindent Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. 

\begin{description}[leftmargin=!,labelwidth=\widthof{\bfseries Example:}]
  \item [Example:] Suppose this is an example. I would like the example to be indented (yay, it is!), and I would like the text on the next line of the example to line up with the letter ``S" in ``Suppose" at the beginning of the first sentence in the example. 
\end{description}

\noindent Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph.
\end{document}

Answer 2

您永远不需要\indent或\noindent在文档中，段落的布局应该是文档范围的设置，而不是每次都要指定的东西。也永远不要用 结束段落\\（LaTeX 在日志中对此发出警告）

\documentclass[letterpaper,12pt,titlepage,openright,twoside,final]{book}
\usepackage{parskip}
\newenvironment{example}
               {%
\sbox0{\textbf{example}: }%
\list{}{\labelwidth\wd0 \leftmargin\wd0 \labelsep 0pt }
             \item[\usebox0]}
               {\endlist}

\begin{document}

Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph.%no! \\

\begin{example}
Suppose this is an example. I would like the example to be indented (yay, it is!), and I would like the text on the next line of the example to line up with the letter ``S'' in ``Suppose'' at the beginning of the first sentence in the example.%no!! \\
\end{example}

Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph.
\end{document}

Answer 3

另一种可能性是使用该linegoal包，它测量插入点处的线路剩余空间：

\documentclass[letterpaper,12pt,titlepage,openright,twoside,final]{book}
\usepackage{hanging}
\usepackage{linegoal}

\begin{document}

\noindent Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. \\

\textbf{Example}: \parbox[t]{\linegoal}{Suppose this is an example. I would like the example to be indented (yay, it is!), and I would like the text on the next line of the example to line up with the letter ``S" in ``Suppose" at the beginning of the first sentence in the example. \\h. Words are here, and they form a paragraph. \\}

\noindent Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph. Words are here, and they form a paragraph.

\end{document}
