链接未着色

Question

如下面的 MCE 所示，如果hyperref要求 的链接着色，则 的链接 intopdf不着色。

\documentclass{article}
\usepackage[colorlinks]{hyperref}%
\usepackage{intopdf}
\begin{document}
The source of the document is attached
\attachandlink{\jobname.tex}[application/x-tex]{The source of this
  document}{here}.

\url{www.test.org}
\end{document}

甚至连常用的\PassOptionsToPackage技巧都不管用：

\PassOptionsToPackage{colorlinks}{hyperref}%
\documentclass{article}
\usepackage{intopdf}
\begin{document}
The source of the document is attached
\attachandlink{\jobname.tex}[application/x-tex]{The source of this
  document}{here}.

\url{www.test.org}
\end{document}

您知道发生了什么吗？并且知道如何解决这个问题？

Answer 1

中的实现intopdf.sty表明colorlinks尚不支持。以下示例是尝试。

\documentclass{article}
\usepackage[colorlinks]{hyperref}
\usepackage{intopdf}

% patch \intopdf_attach_link:nnnnn
\usepackage{xpatch}
\ExplSyntaxOn
\makeatletter
\xpatchcmd \intopdf_attach_link:nnnnn
  {#5}
  {
    \group_begin:
    \cs_if_free:NF\@urlbordercolor{
      \Hy@colorlink\@urlcolor
    }
    #5
    \group_end:
  }
  {}{\fail}
\makeatother
\ExplSyntaxOff

\begin{document}
The source of the document is attached
\attachandlink{\jobname.tex}[application/x-tex]{The source of this
  document}{here}. 

\url{www.test.org}
\end{document}
