如果末尾有引用，则自动生成简短标题

Question

我有很多要引用的图表，我更喜欢在图表列表中给出简短的引用，即不提供来源，不幸的是，当我必须修复拼写错误等时，我需要更改简短标题以及完整标题。有没有一种好的方法可以只命名一次图表？（也许在文档中使用包含简短标题的变量，或者可能有更优雅的方法？）

\documentclass{article}

\usepackage[backend=biber]{biblatex}
\usepackage{caption}
\usepackage[demo]{graphicx}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
    @article{A01,
        author = {Albert Einstein},
        title = {the true about tree},
        journaltitle = {Annalen der Physik},
        year = {1905},
        volume = {322},
        number = {10},
        pages = {891--921}
    }
\end{filecontents}
\addbibresource{\jobname.bib}

\newtoks\shortcap
\shortcap={foo bar baz}


\begin{document}

\listoffigures  


\begin{figure}
\centering
\includegraphics[width=3.0in]{example-image-a}
\shortcap={Some Text}
\caption[\the\shortcap]{\the\shortcap, Source:~\cite{A01}}
\end{figure}


\end{document}

Answer 1

我会采取相反的方式；定义不同的命令允许在棘手的情况下使用原始命令。

\begin{filecontents}{\jobname.bib}
    @article{A01,
        author = {Albert Einstein},
        title = {the true about tree},
        journaltitle = {Annalen der Physik},
        year = {1905},
        volume = {322},
        number = {10},
        pages = {891--921}
    }
\end{filecontents}

\documentclass{article}

\usepackage[backend=biber]{biblatex}
\usepackage{caption}
\usepackage{graphicx}
\usepackage{xparse}

\addbibresource{\jobname.bib}

\NewDocumentCommand{\Caption}{om}{%
  \IfNoValueTF{#1}
    {\caption{#2}}
    {\caption[#2]{#2. Source:~\cite{#1}}}%
}

\begin{document}

\listoffigures  


\begin{figure}[htp]
\centering
\includegraphics[width=3.0in]{example-image-a}
\Caption[A01]{Some text}
\end{figure}

\begin{figure}[htp]
\centering
\includegraphics[width=3.0in]{example-image-b}
\Caption{Some text}
\end{figure}

\end{document}

一种不同的方法，您可以添加完整的最终文本。

\begin{filecontents}{\jobname.bib}
    @article{A01,
        author = {Albert Einstein},
        title = {the true about tree},
        journaltitle = {Annalen der Physik},
        year = {1905},
        volume = {322},
        number = {10},
        pages = {891--921}
    }
\end{filecontents}

\documentclass{article}

\usepackage[backend=biber]{biblatex}
\usepackage{caption}
\usepackage{graphicx}
\usepackage{xparse}

\addbibresource{\jobname.bib}

\NewDocumentCommand{\sourcecaption}{omm}{%
  \IfNoValueTF{#1}
    {\caption[#2]{#2#3}}
    {\caption[#1]{#2#3}}%
}

\begin{document}

\listoffigures  


\begin{figure}[htp]
\centering
\includegraphics[width=3.0in]{example-image-a}
\sourcecaption{Some text}{. Source:~\cite{A01}}
\end{figure}

\begin{figure}[htp]
\centering
\includegraphics[width=3.0in]{example-image-b}
\sourcecaption[Some short text]{Some very long text}{, based on~\cite{A01}}
\end{figure}

\end{document}

Answer 2

您还可以使用在 lof 中消失的特定 cite 命令：

\documentclass{article}

\usepackage[backend=biber]{biblatex}
\usepackage{caption}
\addbibresource{biblatex-examples.bib}

\newbool{showcites}
\DeclareCiteCommand\hiddencite{}{}{}{}
\DeclareRobustCommand\nottoccite[1][Source:~]{\ifbool{showcites}{#1\cite}{\hiddencite}}


\begin{document}

\boolfalse{showcites}
\listoffigures
\booltrue{showcites}

\begin{figure}
\centering
blub
\caption{blalbl 
 \nottoccite{shore}%
 \nottoccite[, ][50]{aksin}%
 \nottoccite[, and based on~][Vol][3]{herrmann}}
\end{figure}


\end{document}

但我不喜欢摆弄逗号和文本，因此从长远来看，我可能会简单地使用通用命令让文本在 lof 中消失：

\documentclass{article}

\usepackage[backend=biber]{biblatex}
\usepackage{caption}
\addbibresource{biblatex-examples.bib}

\newbool{show}
\DeclareRobustCommand\notintoc[1]{\ifbool{show}{#1}{}}


\begin{document}

\boolfalse{show}
\listoffigures
\booltrue{show}

\begin{figure}
\centering
blub
\caption{blalbl 
\notintoc{Source:~\cite{shore}, \cite[50]{aksin}, and based on \cite[Vol][3]{herrmann}}}
\end{figure}


\end{document}
