如何将包含可变长度标题的段落的文本与段落的第一行全局左对齐？

Question

我有几个paragraph，每个都有不同长度的唯一标题：

\documentclass[12pt]{article}

\begin{document}

\subsection{Subsection 1}

\paragraph{Title}
Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here.

\subsection{Subsection 2}

\paragraph{Long Title}
Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here.

\paragraph{Long Long Title}
Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here.

\end{document}

我正在寻找一个全局设置，它可以以可变的方式格式化每个段落的文本，例如（忽略“...”）：

第1节

标题此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。......此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。

第2节

长标题此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。

长长标题此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。此处输入段落文本。...........此处输入段落文本。

我确信有enumitem解决方案，但是我想坚持使用paragraphs 并远离变通方法。我相信and/orenumitem的一些用法可能有效，但我不确定如何这样做。\hangindent\hangafter

Answer 1

你可以\myparagraph这样定义：

\usepackage{calc}  %% provides `\widthof` macro
\newlength{\mylen}
\newlength{\mylength}
\newcommand{\myparagraph}[2][]{%
\setlength{\mylen}{\widthof{\textbf{#2}}}
\setlength{\mylength}{\dimexpr\mylen+1em\relax}
\paragraph[#1]{#2}
\hangindent=\mylength
}

然后\myparagraph{Title}在需要悬挂时使用。

\documentclass{article}
\usepackage{calc}
\newlength{\mylen}
\newlength{\mylength}
\newcommand{\myparagraph}[2][]{%
\setlength{\mylen}{\widthof{\textbf{#2}}}
\setlength{\mylength}{\dimexpr\mylen+1em\relax}
\paragraph[#1]{#2}
\hangindent=\mylength
}

\begin{document}

\subsection{Subsection 1}
\myparagraph{Title}
Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here.

\subsection{Subsection 2}
\myparagraph{Long Title}
Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here.

\myparagraph{Long Long Title}
Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here. Paragraph text here.

\end{document}
