表格、图表等的交叉引用

Question

编写APS稿件时，要求当“Table, Figure”出现在句首时，应以完整形式出现，否则，以缩写形式出现为“Tab., Fig.”。

使用时\ref{}，需要手动决定并输入所指的名称；另一方面，使用\autoref{}，虽然会自动带来所指的名称，但据我所知，它无法判断这些名称是否出现在句子的开头。

那么，有没有一种自动化的方法来满足上述要求，而不用每次都手动输入？

Answer 1

只要\nonfrenchspacing你可以根据以下内容进行分叉\spacefactor：

\documentclass{article}
\usepackage{hyperref}%
\makeatletter
\newcommand\sfcodefork{%
  \ifnum\the\spacefactor=1000 \expandafter\@firstoftwo\else\expandafter\@secondoftwo\fi
}%
\renewcommand\figureautorefname{\sfcodefork{Fig.\texorpdfstring{\null}{}}{Figure}}
\renewcommand\tableautorefname{\sfcodefork{Tab.\texorpdfstring{\null}{}}{Table}}

\makeatother

\begin{document}

\nonfrenchspacing

\section{A section}

\begin{figure}%
\rule{1cm}{1cm}%
\caption{caption of figure.}\label{label of figure}%
\end{figure}%

\begin{table}%
\begin{tabular}{ll}
left&right\\
\end{tabular}
\caption{caption of table.}\label{label of table}%
\end{table}%

References at beginning of sentence:
\autoref{label of figure} is referenced.
\autoref{label of table} is referennced. 

We can refer \autoref{label of figure} in the middle of a sentence.

We can refer \autoref{label of table} in the middle of a sentence.

\end{document}

Answer 2

扩展示例由 Ronald Klopp 提供我建议实现一个\autoref-variant，它也检查 hmode。

作为副作用，这提供了通过在前面添加 来“欺骗”测试为“完整”形式的可能性\therewashmodefalse。\hmodeckeckautoref我思考\null 您可以通过在前面添加来欺骗测试，使其变为简短形式\hmodeckeckautoref。

另一个副作用是，这可能会解决您收到消息的一些情况
! Improper \spacefactor.

我建议小心使用它并仔细检查事情是否按预期进行。

\documentclass{article}
\usepackage{hyperref}%
\makeatletter
\newif\iftherewashmode\therewashmodetrue
\newcommand\hmodeckeckautoref{\ifhmode\else\global\therewashmodefalse\fi\autoref}
\newcommand\sfcodefork{%
  \iftherewashmode\expandafter\@firstoftwo\else\global\therewashmodetrue\expandafter\@secondoftwo\fi{%
    \ifnum\spacefactor=1000 \expandafter\@firstoftwo\else\expandafter\@secondoftwo\fi
  }{\@secondoftwo}%
}%
\renewcommand\figureautorefname{\sfcodefork{Fig.\texorpdfstring{\null}{}}{Figure}}
\renewcommand\tableautorefname{\sfcodefork{Tab.\texorpdfstring{\null}{}}{Table}}

\makeatother

\begin{document}

\nonfrenchspacing

\section{A section}

\begin{figure}%
\rule{1cm}{1cm}%
\caption{caption of figure.}\label{label of figure}%
\end{figure}%

\begin{table}%
\begin{tabular}{ll}
left&right\\
\end{tabular}
\caption{caption of table.}\label{label of table}%
\end{table}%

References at beginning of sentence:
\hmodeckeckautoref{label of figure} is referenced.
\hmodeckeckautoref{label of table} is referennced. 

References at beginning of paragraph:

\hmodeckeckautoref{label of figure} is referenced.

\hmodeckeckautoref{label of table} is referennced. 

We can refer \hmodeckeckautoref{label of figure} in the middle of a sentence.
