我正在尝试制作一个连续的小节标题，并在标题后插入一个长破折号。我成功做到了，但破折号后的间距有细微的差异。我希望得到与第二段相同的输出（不使用小节）。
\documentclass[12pt]{article}
\usepackage{lipsum, titlesec}
\titleformat{\subsubsection}[runin]
{\normalfont\sffamily\bfseries}{}{0em}{}[ --- ]
\begin{document}
\subsubsection{A brand new template} Until now, we have have been using
a combination of markdown and pandoc for producing both the draft and the final
version of an article.\\
\noindent \textbf{\sffamily A brand new template ---} Until now, we have have
been using a combination of markdown and pandoc for producing both the draft
and the final version of an article.
\end{document}

您也必须更改\titlespacingsubsubsection 命令：
\documentclass[12pt]{article}
\usepackage{lipsum, titlesec}
\titleformat{\subsubsection}[runin]
{\normalfont\sffamily\bfseries}
{}{0em}{}
[\mbox{ --- }]
\titlespacing{\subsubsection}
{0pt}% left
{3.25ex plus 1ex minus .2ex}% before
{0pt}% after
\begin{document}
\subsubsection{\sffamily A brand new template}Until now, we have have been using
a combination of markdown and pandoc for producing both the draft and the final
version of an article.
\noindent \textbf{\sffamily A brand new template ---} Until now, we have have
been using a combination of markdown and pandoc for producing both the draft
and the final version of an article.
\subsubsection{\sffamily A brand new template}Until now, ...
\noindent \textbf{\sffamily A brand new template ---} Until now, ...
\end{document}
您还可以加载包microtype：

这主要取决于您是否希望破折号周围的空格参与线条的拉伸/收缩。
您还需要删除通常在标题后添加的空格，这可以使用 来完成\titlespacing。您可以在 文档的第 9.2 节末尾找到标准参数titlesec；因为\subsubsection它是
\titlespacing*{\subsubsection}{0pt}{3.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}
参数为
- 缩进（您希望它保持为零）
- 标题前的垂直空间（您希望它相同）
- 标题后的水平空间（您希望它为零）
\titlespacing和之间的区别\titlespacing*对于连贯标题来说无关紧要。对于块标题，后者会消除以下段落的缩进。
如果您希望空间不参与拉伸/收缩：
\documentclass[12pt]{article}
\usepackage{lipsum, titlesec}
\titleformat{\subsubsection}[runin]
{\normalfont\sffamily\bfseries}
{}
{0em}
{}
[\mbox{ --- }]
\titlespacing*{\subsubsection}{0pt}{3.25ex plus 1ex minus .2ex}{0pt}
\begin{document}
\subsubsection{A brand new template}
Until now, we have have been using a combination of markdown and
pandoc for producing both the draft and the final version of an article.
\noindent\textbf{\sffamily A brand new template\mbox{ --- }}%
Until now, we have have been using a combination of markdown and
pandoc for producing both the draft and the final version of an article.
\end{document}

\titleformat{\subsubsection}[runin]

[ --- \hspace*{0pt}]

我们\hspace*{0pt}确保破折号后的空格不会被删除。

希望这应该接近你想要的。我在小节标题前使用了简短的语法：
\documentclass[12pt]{article}
\usepackage{lipsum, titlesec}
\usepackage{lipsum}
\titleformat{\subsubsection}[runin]
{\normalfont\sffamily\bfseries}{}{-0.2em}{}[ --- ]
\titlespacing{\subsubsection}{0pt}{*3.2}{0.25em}
\begin{document}
\lipsum[2]
\subsubsection{A brand new template} Until now, we have have been using
a combination of markdown and pandoc for producing both the draft and the final
version of an article.\\
\noindent \textbf{\sffamily A brand new template ---} Until now, we have have
been using a combination of markdown and pandoc for producing both the draft
and the final version of an article.
\end{document}
