我如何忽略 titlesec 包并创建一个没有 runin 的子部分？

Question

我正在使用 titlesec 包来设置 runin 小节标题。但是，我有时只想要这个，如果我尝试用 \ 换行，它要么会抛出错误，要么会添加一些奇怪的缩进。有人能帮忙吗？

% Inline subsection
\usepackage{titlesec}
\titleformat{\subsection}[runin]% runin puts it in the same paragraph
        {\bfseries}% formatting commands to apply to the whole heading
        {\thesubsection}% the label and number
        {0.5em}% space between label/number and subsection title
        {\large}% formatting commands applied just to subsection title
        []% punctuation or other commands following subsection title

Answer 1

这是一个相当奇怪的要求。无论如何，你可以这样做。

\documentclass{article}

%\usepackage{xparse} % uncomment if using LaTeX prior to 2020-10-01

\usepackage{titlesec}
\titleformat{\subsection}[runin]% runin puts it in the same paragraph
        {\bfseries}% formatting commands to apply to the whole heading
        {\thesubsection}% the label and number
        {0.5em}% space between label/number and subsection title
        {}% formatting commands applied just to subsection title
        []% punctuation or other commands following subsection title

\makeatletter
\NewDocumentCommand{\psubsection}{sO{#3}m}{%
  \IfBooleanTF{#1}{\subsection*{#3}}{\subsection[#2]{#3}}%
  \mbox{}\par\nopagebreak\@afterheading
}
\makeatother

\begin{document}

\section{Test}

\subsection{Run in}
Some text

\psubsection{Not run in}
Some text

\end{document}

我删除了\large，因为它与连贯的标题不协调。

Answer 2

来，试试这个：

\subsubsection{My header (singled out)}
\paragraph{}\noindent
% paragraph

如果你经常使用它，你可以把它放入命令中

\newcommand{\singlesubsec}[1]{\subsection{#1}\paragraph{}\noindent}

然后你可以使用它（替换上面的内容）作为

\singlesubsec{My header (singled out)}
% paragraph

梅威瑟：

\documentclass{article}

% Inline subsection
\usepackage{titlesec}
\titleformat{\subsection}[runin]% runin puts it in the same paragraph
        {\bfseries}% formatting commands to apply to the whole heading
        {\thesubsection}% the label and number
        {0.5em}% space between label/number and subsection title
        {\large}% formatting commands applied just to subsection title
        []% punctuation or other commands following subsection title
        
\usepackage{lipsum} % just for dummy text
        
\begin{document}

    \subsection{Header in-line}
    
    \lipsum[1]
    
    \subsection{Header on own}
    \paragraph{}\noindent
    \lipsum[1]
    
\end{document}
