具有结构层次的参考文献

在我目前正在处理的文档中，我们经常更改章节/部分等的层次结构。因此，在文本中，我想在类似这样的句子中引用当前的层次结构级别

In this chapter we will talk about ...

由于结构经常变化，我想将当前层次结构的级别名称（上例中的“章节”）添加到某些命令中，以便当我们再次更改结构时，它会自动适应。

但是我找不到这样的命令。大多数命令都用于获取当前章节的标题或对其他章节的引用（包括章节编号）。

因此，根据这个例子，我需要写什么才能\someCommand获得当前章节/部分/小节/等的名称？

\documentclass[a4paper]{memoir}
\begin{document}

\chapter{Example-Chapter}

Current level: \someCommand - should be "chapter" and not "Example-Chapter"

\section{Example-Section}

Current level: \someCommand - should be "section" and not "Example-Section"

\end{document}

\chapter您可以使用重置链接计数器的事实，并且同样的情况也会发生\section。

\documentclass[a4paper]{memoir}

\newcommand{\someCommand}{%
  \ifnum\value{section}=0
    chapter%
  \else
    \ifnum\value{subsection}=0
      section%
    \else
      subsection%
    \fi
  \fi
}
\setsecnumdepth{subsection}

\begin{document}

\chapter{Example chapter}

Current level: \someCommand, should be ``chapter''

\section{Example section}

Current level: \someCommand, should be ``section''

\subsection{Example subsection}

Current level: \someCommand, should be ``subsection''

\section{Example section}

Current level: \someCommand, should be ``section''

\end{document}

此版本还适用于未编号结构层级。结构宏定义\chapter等\section在开头以结构层级名称和编号的定义进行扩展。

\documentclass{report}
\setcounter{secnumdepth}{-1}

\usepackage{etoolbox}
\newcommand*{\tmp}[3]{%
  \pretocmd#1{%
    \gdef\StructureLevelNumber{#2}%
    \gdef\StructureLevelName{#3}%
  }{}{%
    \errmessage{Cannot patch \string#1}%
  }%
}
\tmp\part{-1}{part}
\tmp\chapter{0}{chapter}
\tmp\section{1}{section}
\tmp\subsection{2}{subsection}
\tmp\subsubsection{3}{subsubsection}
\tmp\paragraph{4}{paragraph}
\tmp\subparagraph{5}{subparagraph}

\newcommand*{\test}{%
  We are in structure level ``\StructureLevelName'' %
  (\StructureLevelNumber).%
}

\begin{document}
\part{Part title}
\test
\chapter{Chapter title}
\test
\section{Section title}
\test
\subsection{Subsection title}
\test
\subsubsection{Subsubsection title}
\test
\paragraph{Paragraph title.}
\test
\subparagraph{Subparagraph title.}
\test
\end{document}

该包zref支持定义可存储在标签（\zlabel、\zref@label...）和引用（\zref、\zref@extract...）中的新属性。

下面的例子仅使用整数来标识结构级别，并通过宏为结构级别生成名称\StructureLevelName。

\documentclass{report}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{color}
\setcounter{secnumdepth}{-1}

虽然这不是一个独特的新答案，但我想添加它以供参考：

在对@egreg 的答案进行了一些实验之后，我还删除了“静态”分段标签，并用用途替换它们，因此它与文档中hyperref的使用保持一致。\autoref

\documentclass[a4paper]{memoir}
\usepackage{hyperref}

\newcommand{\structuringLevel}{%
  \ifnum\value{section}=0
    \chapterautorefname%
  \else
    \ifnum\value{subsection}=0
      \sectionautorefname%
    \else
      \subsectionautorefname%
    \fi
  \fi
}
\setsecnumdepth{subsection}

\begin{document}

\chapter{Example chapter}

Current level: \someCommand, should be ``chapter''

\section{Example section}

Current level: \someCommand, should be ``section''

\subsection{Example subsection}

Current level: \someCommand, should be ``subsection''

\section{Example section}

Current level: \someCommand, should be ``section''

\end{document}

答案4

这里有一个基于cleveref包的解决方案。

优点：

  • 它不需要低级代码。这使 LaTeX 代码更易于阅读。
  • 它区分大写（例如“Section”）和非大写（例如“section”）。它还提供复数形式，以防万一 ;)。
  • 我们使用标准包：无需定义自己的函数。

缺点：

  • 我们必须标记各个部分\label（然而，这是编写文档时的通常程序）

示例代码

\documentclass[a4paper]{memoir}

\usepackage{cleveref}

%Redefining the names associated to the 'chapter' counter
\crefname{chapter}{chapter}{chapters} %uncapitalized
\Crefname{chapter}{Chapter}{Chapters} %capitalized
%Redefining the names associated to the 'section' counter
\crefname{section}{section}{sections}
\Crefname{section}{Section}{Sections}
%Redefining the names associated to the 'subsection' counter
\crefname{subsection}{subsection}{subsections}
\Crefname{subsection}{Subsection}{Subsections}
%... 
%You can name as many sectioning commands as you want
%...
%Redefining the names associated to the 'subparagraph' counter
\crefname{subparagraph}{subparagraph}{subparagraphs}
\Crefname{subparagraph}{Subparagraph}{Subparagraphs}

%Here set the name of the lowest section that has to be named
\setsecnumdepth{subparagraph}

\begin{document}

\chapter{Example chapter}\label{sec:level01}

Current level: \namecref{sec:level01}, should be ``chapter''.\\ %Uncapitalized name
\nameCref{sec:level01} is the current level. %Capitalized name

\section{Example section}\label{sec:level02}

Current level: \namecref{sec:level02}, should be ``section''.\\
\nameCref{sec:level02} is the current level.

\subsection{Example subsection}\label{sec:level03}

Current level: \namecref{sec:level03}, should be ``subsection''.\\
\nameCref{sec:level03} is the current level.

\subparagraph{Example subparagraph}\label{sec:level05}
Current level: \namecref{sec:level05}, should be ``subparagraph''.
\nameCref{sec:level05} is the current level.

\section{Example section}\label{sec:level04}

Current level: \namecref{sec:level04}, should be ``section''.\\
\nameCref{sec:level04} is the current level.

\end{document}
