定理

我排版了一本包含问题和解决方案的书。我需要获取一个简短问题名称的列表。我期望会有类似于图片的方法：

\caption[Figure name for List of Figures]{Caption name}

以下是获取问题列表的方法的总结。

定理

这种方法似乎比其他方法更接近：

\documentclass{book}

\usepackage{ntheorem}
\theoremlisttype{all}
\newtheorem{Problem}{Problem}[chapter]

\begin{document}

\listtheorems{Problem}

\chapter{foo}

\begin{Problem}[Short foo name]
  Foo!
\end{Problem}

\chapter{bar}

\begin{Problem}[Short bar name]
  Bar!
\end{Problem}

\end{document}
  • 这里的问题是，问题中也显示了短名称。也许可以定义一个新的\newtheoremlisttype...

thm工具

这是 MWE thmtools（来自https://tex.stackexchange.com/a/2500/8992）

\documentclass{book}

\usepackage{amsthm}
\usepackage{thmtools}
\declaretheorem[numberwithin=chapter]{hypothesis}
\declaretheorem[numberwithin=chapter]{theorem}

\begin{document}

\renewcommand{\listtheoremname}{List of Hypotheses}
\listoftheorems[ignoreall,show={hypothesis}]

\chapter{foo}

\begin{hypothesis}[X-Y-relationship]
There is a positive relationship between X and Y.
\end{hypothesis}

\begin{theorem}
Some text.
\end{theorem}

\end{document}

黑客

以下是一些黑客攻击的 MWE（来自https://tex.stackexchange.com/a/6917/8992)：

\documentclass{book}

\usepackage{ntheorem}
\newtheorem{hypo}{Hypothesis}[chapter]
\newtheorem{hypolist}{Hypothesis}[chapter]

\newcommand*\hypothesis[1]{%
    \stepcounter{hypolist}%
    \addtheoremline{hypolist}{#1}%
    \begin{hypo}#1\end{hypo}
}

\begin{document}

\chapter*{List of Hypotheses}
\listtheorems{hypolist}

\chapter{foo}

\hypothesis{There is a positive relationship between $X$ and $Y$.}

\chapter{bar}

\hypothesis{There is a positive relationship between $X$ and $Z$.}
\hypothesis{There is a positive relationship between $Z$ and $Y$.}

\end{document}
  • 无法为问题列表指定一个较短的名称

答案1

您可以简单地重新定义plain定理样式以忽略“归因”部分。默认定义是

\newtheoremstyle{plain}
  {\item[\hskip\labelsep \theorem@headerfont ##1\ ##2\theorem@separator]}%
  {\item[\hskip\labelsep \theorem@headerfont ##1\ ##2\ (##3)\theorem@separator]}

所以你可以说

\documentclass{book}

\usepackage{ntheorem}
\theoremlisttype{all}

\makeatletter
\newtheoremstyle{problem}
  {\item[\hskip\labelsep \theorem@headerfont ##1\ ##2\theorem@separator]}%
  {\item[\hskip\labelsep \theorem@headerfont ##1\ ##2\theorem@separator]}
\makeatother
\theoremstyle{problem}
\newtheorem{Problem}{Problem}[chapter]

\begin{document}

\chapter*{List of problems}
\listtheorems{Problem}

\chapter{foo}

\begin{Problem}[Short foo name]
  Foo!
\end{Problem}

\chapter{bar}

\begin{Problem}[Short bar name]
  Bar!
\end{Problem}

\end{document}

答案2

对于这种情况，我会倾向于定义自己的包environment，而不是侵入现有包的内部。

在下面的代码中，我定义了两个环境供您使用，具体取决于您的需要。这两种方法都依赖于etoolbox对于一些命令-第二个环境需要xparse对于具有两个可选参数的环境。

两个环境都添加到\jobname.prb使用命令创建的环境\@starttoc。

问题

.prb该环境采用可选参数，如果不为空，则会添加到该参数中。

% define the Problem environment
%
% Takes an optional description- if it is not empty, 
% then it is added to \jobname.prb
\newcounter{problem}
\newenvironment{problem}[1][]{\refstepcounter{problem}%
    {\bfseries Problem~\theproblem} %
    \ifstrempty{#1}%
    {% 
        % if #1 is empty, do nothing
    }%
    {%
        % otherwise add it to jobname.prb
        \addcontentsline{prb}{subsection}{#1}%
    }%
}{}

这可以用作

\begin{problem}
\lipsum[2]
\end{problem}

或者

\begin{problem}[Description goes here, and added to jobname.prb]
\lipsum[2]
\end{problem}

其他问题

这个有点复杂，因为它需要二可选参数。

% define another Problem environment, just for demonstration
%
% Takes TWO optional arguments:
%   #1: long description, used for \jobname.prb if #2 is not present
%   #2: short description, used for \jobname.prb if present
\newcounter{otherproblem}
\NewDocumentEnvironment{otherproblem}{O{} O{}}{\refstepcounter{otherproblem}%
    {\bfseries Problem~\theotherproblem} %
    \ifstrempty{#2}%
    {% 
        % if #2 is empty, then check for #1, and 
        % use it for jobname.prb if present
        \ifstrempty{#1}%
        {%
            % if #1 is empty, do nothing 
        }%
        {%
            % otherwise, display it, and add it to
            % \jobname.prb
            {[\bfseries #1]}%
            \addcontentsline{prb}{subsection}{#1}%
        }%
    }%
    {%
        % if #2 is not empty, use it for the 
        % \jobname.prb
        \addcontentsline{prb}{subsection}{#2}%
        \ifstrempty{#1}%
        {}%
        {%
            {[\bfseries #1]}%
        }%
    }%
}{}

示例用法

\begin{otherproblem}[Long description][Short description for list]
\lipsum[2]
\end{otherproblem}

或者

\begin{otherproblem}[Long description displayed and added to list]
\lipsum[2]
\end{otherproblem}

或者

\begin{otherproblem}[][Short description for list, nothing displayed]
\lipsum[2]
\end{otherproblem}
