这是对tex4ht:自定义列表...(第 1 部分,共 2 部分)
我有一个自定义列表<things>
。下面的代码提供了从 中的每个项目List of cmh
到其在页面上的位置的链接。我希望(在 html 版本中)每次出现的 输出都\cmhcommand
链接到 中的相关位置List of cmh
。
mwe.tex
\documentclass{article}
\usepackage{cmhloc}
\begin{document}
\tableofcontents
\section{normal section}
\cmhcommand{Here is some text}
some text
\section{another secton}
\cmhcommand{Another text}
\cmhcommand{some more}
\listofcmh
\end{document}
cmhloc.sty
\ProvidesPackage{cmhloc}
\newcommand{\cmhcommand}[1]{\addcontentsline{cmh}{subsection}{#1}#1}
\newcommand{\listofcmh}{\subsection*{List of cmh}\@starttoc{cmh}}
\endinput
cmhloc.4ht
\ConfigureToc{cmh}{\HCode{<div class="sectionToc">}}{~}{}{\HCode{</div>\Hnewline}}
\renewcommand\listofcmh{\subsection*{List of cmh}\TableOfContents[cmh]}
\endinput
我用来生成版本的编译html
是
htlatex mwe.tex
答案1
在这种情况下,我们需要为每个 构建唯一的 id \cmhcommand
,作为 TOC 的链接。我们将sty
稍微修改一下文件:
\ProvidesPackage{cmhloc}
\newcommand\printcmhentry[1]{#1}
\newcommand{\cmhcommand}[1]{\addcontentsline{cmh}{subsection}{#1}\printcmhentry{#1}}
\newcommand{\listofcmh}{\subsection*{List of cmh}\@starttoc{cmh}}
\endinput
这样,我们只需要重新定义命令,而不需要在文件中\printcmhentry
重复逻辑:\cmhcommand
4ht
\RequirePackage{etoolbox}
\def\toccmh#1#2#3{%
\bgroup% make the changes local
\Configure{TocLink}{% This will print the link in TOC.
\Link{##2}{\@nameuse{cmhcn-##4}}##4\EndLink% We need to construct the ID parameter in second parameter for \Link
}
\HCode{<div class="sectionToc">}#2\HCode{</div>\Hnewline}% Print the entry
\egroup%
}%
\newcount\cmhcount % each cmhentry will have it's unique idntifier
\renewcommand\printcmhentry[1]{%
\advance\cmhcount by1\relax%
\edef\cmhlink{cmh-\the\cmhcount}% this will be the id for the corresponding entry in the \listcmh
\csxdef{cmhcn-#1}{\cmhlink}\Link{\cmhlink}{}#1\EndLink} % we use the entry text in csname,
% in order to be able to retrieve the id later
% in the \listcmh entries
\append:def\listofcmh{\TableOfContents[cmh]}
\endinput
在这种情况下,\toccmh
宏被定义而不是\ConfigureToc{cmh}
,它更灵活。我们使用\Configure{TocLink}
来配置目录条目中的超链接,第一个参数是的id \addcontentsline
,第二个参数是条目的锚点。例如\@nameuse{cmhcn-##4}
扩展到\nameuse{cmhcn-Here is some text}
。这个宏在中定义\renewcommand\printcmhentry
,它包含文本链接到的id。
结果如下:
<h3 class="sectionHead"><span class="titlemark">1 </span> <a
id="x1-20001"></a>normal section</h3>
<a
id="x1-2001"></a>
<!--l. 9--><p class="noindent" ><a
href="#cmh-1">Here is some text</a> some text
</p>
<h3 class="sectionHead"><span class="titlemark">2 </span> <a
id="x1-30002"></a>another secton</h3>
<a
id="x1-3001"></a>
<!--l. 13--><p class="noindent" ><a
href="#cmh-2">Another text</a>
</p><!--l. 16--><p class="indent" > Inside paragraph: <a
id="x1-3002"></a><a
href="#cmh-3">some more</a>. It doesn’t work well.
</p><!--l. 25--><p class="noindent" >
</p>
<h4 class="likesubsectionHead"> <a
id="x1-40002"></a>List of cmh</h4>
<div class="tableofcontents"> <div class="sectionToc"><a
href="#x1-2001" id="cmh-1">Here is some text</a></div>
<div class="sectionToc"><a
href="#x1-3001" id="cmh-2">Another text</a></div>
<div class="sectionToc"><a
href="#x1-3002" id="cmh-3">some more</a></div>
</div>
