可点击的包含图形可查看交叉引用数据

Question

我想在我的健壮的外部化库。我想解析aux文件，提取与标签相关的行，例如：

\newlabel{sec:dependencies}{{3.4}{7}{Dependencies}{subsection.3.4}{}}
\newlabel{sec:dependencies@cref}{{[subsection][4][3]3.4}{[1][7][]7}}

并将其输入到我的文档的序言中。作为概念证明，我写道：

\begin{CacheMe}{latex, add to preamble={\usepackage{hyperref}\newlabel{sec:dependencies}{{3.4}{7}{Dependencies}{subsection.3.4}{}}}}
  Hello \ref{sec:dependencies}.
\end{CacheMe}

而且它确实有效！

但有一个恼人的问题：我无法点击链接转到相应的部分（而\ref{sec:dependencies}在文档的任何地方都可以书写）。你知道有没有办法让\includegraphics链接也能正常工作吗？

梅威瑟：

\documentclass{article}

\usepackage{robust-externalize} % You certainly need to download the .sty in github.com/leo-colisson/robust-externalize, and compile with `-shell-escape`, or manually (see doc)
\usepackage{hyperref}

\begin{document}

\section{Dependencies}\label{sec:dependencies}

\begin{CacheMe}{latex, add to preamble={\usepackage{hyperref}\newlabel{sec:dependencies}{{1}{1}{Dependencies}{section.1}{}}}}
  Hello, go to section \ref{sec:dependencies}.
\end{CacheMe}


\end{document}

编辑

我尝试使用 newpax，但它不起作用，链接指向包含的图像本身。我认为问题在于当我使用编译子文件时pdflatex robExt-471D7E5B93E3AC81760E014C437DDD7B.tex，它实际上包含：

\documentclass[,margin=0cm]{standalone}
 \usepackage {hyperref}\newlabel {sec:dependencies}{{2}{2}{Dependencies}{section.2}{}}
\begin{document}%
%% We save the height/depth of the content by using a savebox:
\newwrite\writeRobExt%
\immediate\openout\writeRobExt=\jobname-out.tex%
%
\newsavebox\boxRobExt%
\savebox{\boxRobExt}{%
  Hello, go to section \ref {sec:dependencies}.%
}%
\usebox{\boxRobExt}%
\immediate\write\writeRobExt{%
  \string\def\string\robExtWidth{\the\wd\boxRobExt}%
  \string\def\string\robExtHeight{\the\ht\boxRobExt}%
  \string\def\string\robExtDepth{\the\dp\boxRobExt}%
}%
%

\end{document}

我收到一个警告：

pdfTeX warning (dest): name{section.2} has been referenced but does not exist, 
replaced by a fixed one

因此，我猜想问题可以改写为“如何让 Latex 保留链接，即使该链接不存在于当前文档中”。

这也是 paxfile：

\[{pax}{0.1l}\\
\[{file}{(./robExt-471D7E5B93E3AC81760E014C437DDD7B.pdf)}{
  Size={13783},
  Date={D:20230906164541+02'00'},
}\\
\[{pagenum}{1}\\
\[{page}{1}{0.0 0.0 94.977 8.856}{}\\
\[{annot}{1}{Link}{86.232 -0.996 93.206 9.852}{GoTo}{
  C={[1 0 0 ]},
  H={/I},
  Border={[0 0 1 ]},
  DestLabel={1},
}\\
\[{dest}{1}{1}{Fit}{
}\\

以下是完整的流程，仅供参考。无需逃逸外壳：

1. 创造

\DocumentMetadata{uncompress}
\documentclass{article}
\usepackage{pdfpages,xcolor}
\usepackage{robust-externalize} % You certainly need to download the .sty in github.com/leo-colisson/robust-externalize, and compile with `-shell-escape`, or manually (see doc)
\usepackage{hyperref}
\usepackage{newpax}
\newpaxsetup{usefileattributes=true}
\begin{document}

\section{Test}
\newpage
\robExtConfigure{latex/.append style={do not add margins}, enable manual mode}

\section{Dependencies}\label{sec:dependencies}

\newpage
\section{Test}
\robExtConfigure{latex/.append style={do not add margins}}

\begin{CacheMe}{latex, name output=mycompiledfile, add to preamble={\usepackage{hyperref}\newlabel{sec:dependencies}{{3}{3}{Test}{section.3}{}}}}
  Hello, go to section \ref{sec:dependencies}.
\end{CacheMe}
\mycompiledfile

%%% Uncomment later:
%\includegraphics{\mycompiledfile.pdf}


\ref{sec:dependencies}
\end{document}

2. 编译：

mkdir robustExternalize
pdflatex debug-crossref.tex
# look in debug-crossref-robExt-compile-missing-figures.sh, but it should be:
cd robustExternalize/ && pdflatex -halt-on-error "robExt-471D7E5B93E3AC81760E014C437DDD7B.tex" && cd ..

3. 复制到robExt-471D7E5B93E3AC81760E014C437DDD7B.pdf file主文件夹中（不知道如何使其在子文件夹中工作）：

cp robustExternalize/robExt-471D7E5B93E3AC81760E014C437DDD7B.pdf .

4. 创建文件testnewpax.tex：

\documentclass{article}
% load the lua code
\directlua{require("newpax")}
% write .newpax files for newpax.sty
\directlua
{
newpax.writenewpax("robExt-471D7E5B93E3AC81760E014C437DDD7B")
}
\begin{document}
\end{document}

使用 lualatex 编译该文件：

lualatex testnewpax.tex

Uncomment later取消注释上述文档中的后一行，然后重新编译两次：

pdflatex debug-crossref.tex
pdflatex debug-crossref.tex

发现创建的链接没有指向正确的部分。
