![xr 包 + latexmkrc 不能与 includegraphics 命令一起使用?](https://linux22.com/image/360214/xr%20%E5%8C%85%20%2B%20latexmkrc%20%E4%B8%8D%E8%83%BD%E4%B8%8E%20includegraphics%20%E5%91%BD%E4%BB%A4%E4%B8%80%E8%B5%B7%E4%BD%BF%E7%94%A8%EF%BC%9F.png)
我正在尝试实现所描述的技巧这里使用 xr 包让 latex 引用自动跨多个文件工作。该技术效果很好,除了如果引用的文件中有一个 includegraphics 命令。您可以在此处查看我的最小非工作示例: https://www.sharelatex.com/project/594816fa8920e4376fb8d7a6。具体来说,我有
文件1
\documentclass{article}
%%% HELPER CODE FOR DEALING WITH EXTERNAL REFERENCES
\usepackage{xr}
\makeatletter
\newcommand*{\addFileDependency}[1]{
\typeout{(#1)}
\@addtofilelist{#1}
\IfFileExists{#1}{}{\typeout{No file #1.}}
}
\makeatother
\newcommand*{\myexternaldocument}[1]{
\externaldocument[S]{#1}
\addFileDependency{#1.tex}
\addFileDependency{#1.aux}
}
%%% END HELPER CODE
% put all the external documents here!
\myexternaldocument{File2}
% just to see what's happening
\listfiles
\begin{document}
We would like to reference section \ref{Spicture} of file2.tex
\end{document}
文件2
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\section{Label1}
\label{picture}
This section is referenced by File1.
\begin{figure}
\centering
\includegraphics{{IMG}.png}
\caption{Caption}
\end{figure}
\end{document}
.latexmkrc
add_cus_dep( 'tex', 'aux', 0, 'makeexternaldocument' );
sub makeexternaldocument {
# if the dependency isn't one of the files that this latexmk run will consider, process it
# without this test, we would get an infinite loop!
if (!($root_filename eq $_[0]))
{
system( "latexmk \"$_[0]\"" );
}
}
当我注释掉 file2 中的 includegraphics 命令,然后编译 file1 时,引用工作正常。但是当我取消注释 includegraphics 命令时,从 file1 到 file2 的引用就被破坏了。
有什么建议么?
