定义新的节标题并将文本添加到目录中

Question

我想创建一个名为假设的新部分类型标题。标题也必须出现在目录中。到目前为止，我已经设法创建了标题，但我找不到让它出现在目录中的方法。我希望它像目录中的部分一样出现：章节号.标题计数器号，例如：1.2 假设标题 1 另外，我创建了一个新的标签格式，并希望章节号也出现。请参阅附件 MWE 并请提供建议：

\documentclass[a4paper,12pt]{report}
\usepackage[english]{babel}

\newcounter{assumption}[section]
\newenvironment{assumption}[1][\unskip]{\large\refstepcounter{assumption}\medskip
\noindent{\textbf{Assumption~\thechapter.\theassumption. {\large}#1} \\} \addcontentsline{toc}{assumption} \rmfamily}{\medskip}
\newcommand{\assumptionlabel}[2]{%
\protected@write \@auxout {}{\string \newlabel {#1}{{#2}{}}}
\hypertarget{#1}{#2}}

\begin{document}
\tableofcontents
\chapter{Assumptions Chapter}
\assumption[Assumption Header]
\label{assumptionlabel:some-assumption}
Some assumption text.

\assumption[Assumption Header]
\label{assumptionlabel:some-assumption2}
Some assumption text with reference to Assumption \ref{assumptionlabel:some-assumption}.\\
Instead, I would like:\\
Some assumption text with reference to Assumption 1.1
\end{document}

Answer 1

线路

\addcontentsline{toc}{assumption}

不起作用，因为assumption没有已知的ToC条目类型section等，即还没有\l@assumption宏，但这可以通过以下方式解决

\makeatletter
\let\l@assumption\l@section
\makeatother

以便使用相关的\l@section代替。

现在

\addcontentsline{toc}{assumption}{\protect\numberline{\theassumption}#1}

将在目录中提供相应级别的假设编号和标题section。

现在讨论标签问题：重新定义\@currentlabel以根据需要制作交叉引用格式，无需明确的\hypertarget- 语句 -hyperref足够复杂，可以在有正确标签的情况下“保证”正确的超级锚点。

\documentclass[a4paper,12pt]{report}
\usepackage[english]{babel}
\usepackage{hyperref}

\newcommand{\assumptionname}{Assumption}
\newcounter{assumption}[section]
\makeatletter
\let\toclevel@assumption\toclevel@section% Providing bookmark support
\let\l@assumption\l@section

\newenvironment{assumption}[1][\unskip]{%
  \large\refstepcounter{assumption}%
  % Specific label format
  \protected@edef\@currentlabel{\csname p@assumption\endcsname\assumptionname\ \thechapter.\csname theassumption\endcsname}%
  \medskip%
  \noindent\textbf{\assumptionname~\thechapter.\theassumption.\ \large #1}
  \addcontentsline{toc}{assumption}{\protect\numberline{\thechapter.\theassumption}#1}%
  \medskip% % Empty line here!!!
  \parindent0em

  \rmfamily%
}{\medskip}%
\makeatother


\begin{document}
\tableofcontents
\chapter{Assumptions Chapter}
\begin{assumption}[Assumption Header]
\label{assumptionlabel:some-assumption}%
Some assumption text. \ref{assumptionlabel:some-assumption2}
\end{assumption}

\clearpage
\begin{assumption}[Assumption Header]
  \label{assumptionlabel:some-assumption2}
Some assumption text with reference to \ref{assumptionlabel:some-assumption}.
\end{assumption}
\end{document}
