TeX4ht：超链接和可选证明参数之间的冲突

梅威瑟：

\documentclass{amsart}
\usepackage{hyperref}

\newtheorem{theorem}{Theorem}

\begin{document}
\begin{theorem}\label{thm}
  This is a theorem.
\end{theorem}

\begin{proof}[Proof of Theorem~\ref{thm}]
  This is a proof.
\end{proof}
\end{document}

编译后make4ht，得到

[ERROR]   htlatex: ./test.tex   11   Extra \else.

如果不包含包则不会出错hyperref。另外值得一提的是，如果我们用 替换，也会出现此\begin{proof}[Proof of Theorem~\ref{thm}]问题\begin{proof}[Proof of Theorem~\hyperref[thm]{some theorem}]。

我想知道原因和解决方法。谢谢。

此问题是由于删除了 TeX4ht 中 Hyperref 的一些补充代码而导致的。这样做的原因是与 BibLaTeX 冲突。由于我发现此更改还导致其他问题，我已将原始代码重新引入 TeX4ht 源。与此同时，您可以使用该hyperref-hooks.4ht文件的本地副本：

您的示例现在可以编译，没有错误：
