tex4ebook 转换后，索引未列在目录中，且索引中没有超链接

Question

TeX4ht 尚不支持 Memoir 的索引系统，下面是对此的修复memoir.4ht：

重要的部分是这样的：

\def\:tempa#1|#2|#3\\{%
\html:addr\hbox{\Link-{}{dx\last:haddr}\EndLink}%
\expandafter\protected@write\csname \jobname @idxfile\endcsname{}{\string\beforeentry{\RefFileNumber\FileNumber}{dx\last:haddr}{}}%
\expandafter\protected@write\csname \jobname @idxfile\endcsname{}{\string\indexentry[\@idxfile]{#1}{\thepage}}%

% we use make4ht's splitindex functionality, which produces .ind files in the form of \jobname-idxname.ind
\renewcommand{\printindex}[1][\jobname]{\@input@{\jobname-#1.ind}}

它重新定义了用于将索引信息写入辅助文件的命令，插入超链接目标（这对于从索引链接回文本是必要的），并以所需的格式写入索引条目make4ht。

索引不支持开箱即用，您需要明确调用索引命令在构建文件中。例如，您可以将以下代码保存为build.lua：

Make:htlatex {} 
Make:makeindex {} 
Make:htlatex{}

最后一件事是将索引包含在目录中。您可以尝试此配置文件：

\Preamble{xhtml}
\begin{document}
\RenewDocumentCommand\tableofcontents{s}{\TableOfContents[part,likepart,chapter,likechapter,section,likesection,subsection,likesubsection]}
\EndPreamble

它重新定义\tableofcontents命令来打印带星号的分段命令版本（感谢likechapter等等）。

编译使用：

$ tex4ebook -c config.cfg -e build.lua sample.tex

这是最终的目录：

索引如下：

链接应该指向文本中的正确点。
