scrjura 链接无法使用 tex4ht 转换为 html

Question

这是针对 tex4ht 专家的一个问题。

我正在用德语写合同。MWE：

\documentclass[pagesize, ngerman, fontsize=12pt, parskip=half, ref=nosentence]{scrartcl}
\usepackage[T1]{fontenc}\usepackage[utf8]{inputenc}
\usepackage{babel, scrjura, xspace}


  \usepackage{lmodern}
  \usepackage{microtype}
  \DisableLigatures[f]{encoding = *, family = * }

\begin{document}
\begin{contract}
  \Clause{title=First of seven}
\label{CLA:first}

This is some text.

Some more text.\label{PAR:second-par}

And.

\Clause{title=Second of seven}
\label{CLA:second}

We refer to \ref{CLA:first}.

We refer to \ref{PAR:second-par}.

We refer to \refPar{PAR:second-par}.

We refer to \refParN[arabic]{PAR:second-par}.%%% <= Issue !

\end{contract}
\end{document}

scrjura 软件包附带许多命令来引用合同的不同位置。有些命令不适用于 tex4ht。

如果使用此命令将此示例文件转换为 html：

htlatex example.tex "scrjura" " -cunihtf"

该命令\refParN[arabic]{PAR:second-par}将不会被转换。链接缺失。

scrjura 是配置文件的名称非常有帮助的灵魂曾经为我写过。这是 scrjura.cfg 的代码（对于测试用例，只需将其存储在 example.tex 所在的同一文件夹中）：

\catcode`\:=11
\makeatletter

\Preamble{html,charset=utf-8}

\begin{document} 

\def\qtchr{\expandafter\@gobble\string\"}
\
\ConfigureList{contract}
  {\HCode{<div class=\qtchr contract\qtchr>}}
  {\HCode{</div>}}
  {}{}

\append:def\contract@paragraph@font{\a:contract@paragraph@font} 
\append:def\contract@paragraph@font{\b:contract@paragraph@font} 

\NewConfigure{contract@paragraph@font}{2}
\Configure{contract@paragraph@font}
  {\HCode{<div class=\qtchr paragraph\qtchr>}}
  {\Tg</div>}

 \pend:def\parformat{\a:parformat} 
 \append:def\parformat{\b:parformat} 

 \NewConfigure{parformat}{2}
 \Configure{parformat}
   {\EndP\HCode{<p class=\qtchr para\qtchr>
    <span class=\qtchr sentence\qtchr>}}
   {\Tg</span>}

 \Css{.sentence{margin-left:2em; padding-top: .5em;}}
 \Css{.paragraph{margin: 1em;}}
 \Css{.para{margin: .5em;}}

\EndPreamble 

\catcode`\:=12
\makeatother

\endinput

如果有人知道如何修改 scrjura.cfg 以获得\refPar转换后的链接，我将不胜感激。

顺便说一句，scrjura.sty 几年前使用的\Paragraph{title=First of seven}是现在的\Clause{title=...}。

我已经scrjura.4ht为创建了一个适当的配置文件tex4ht：

\def\qtchr{\expandafter\@gobble\string\"}
\ConfigureEnv{contract}
{\ifvmode\IgnorePar\fi\EndP\HCode{<div class=\qtchr contract\qtchr>}}
{\ifvmode\IgnorePar\fi\end:prevpara\HCode{</div>}}
{}{}

\pend:def\contract@paragraph@font{\a:contract@paragraph@font} 
\append:def\contract@paragraph@font{\b:contract@paragraph@font\gdef\end:prevpara{}} 

\NewConfigure{contract@paragraph@font}{2}
\Configure{contract@paragraph@font}
  {\ifvmode\IgnorePar\fi\end:prevpara\HCode{<div class=\qtchr paragraph\qtchr>}}
  {\Tg</div>}

% \end:prevpara is needed to correctly handle paragraphs
\def\end:prevpara{}
\pend:def\parformat{\end:prevpara\a:parformat} 
\append:def\parformat{\b:parformat\global\let\end:prevpara\c:parformat} 

\NewConfigure{parformat}{3}
\Configure{parformat}
{\EndP\HCode{<p class=\qtchr para\qtchr>\Hnewline
<span class=\qtchr sentence\qtchr>}}
    {\Tg</span>}{\Tg</p>}

\refPar和宏的问题\refParN在于它们依赖于特定的交叉引用结构，这与 不同tex4ht。我已经修补了交叉引用处理宏，\ref@Par使其以某种方式兼容。唯一的问题是这些命令的链接不起作用，但至少文本看起来不错：
