TeX4ht 中具有可选参数配置的环境

TeX4ht 中具有可选参数配置的环境

我尝试在 TeX4ht 中使用可选参数创建配置以下环境

\newenvironment{proof}[1][Proof]{\textit{#1}:\ \ignorespaces}
                            {}

平均能量损失

\documentclass{book}

\newenvironment{proof}[1][]{\def\arg{#1}\ifx\arg\empty\textit{Proof}\else\textit{#1}\fi:\ \ignorespaces}
                          {} 
\begin{document}
\begin{proof}
  Sample text
\end{proof}

\begin{proof}[Proof of Theorem~1]
Sample text
\end{proof}

\end{document}

CFG

\ConfigureEnv{proof}
         {\ifvmode \IgnorePar\fi \EndP\HCode{<statement>\Hnewline\Hnewline<label>Proof</label>}\IgnoreIndent \ShowPar\par}
         {\ifvmode \IgnorePar\fi \EndP\HCode{</statement>}}
         {}{}

我在定义中使用可选参数，如果该参数存在，则应在部分中捕获它<label>xxxxxx</label>，否则应像捕获一样捕获<label>Proof</label>

我得到了错误的输出

<statement>
<label>Proof</label>
<p class="noindent"><italic>Proof </italic>:&#x00A0;Sample text</p>
</statement>

<statement>
<label>Proof</label>
<p class="noindent"><italic>Proof of Theorem&#x00A0;1</italic>:&#x00A0;Sample text
</p></statement>

Proof' was repeating due to the hard written in the in the\ConfigureEnv`，

如何在中添加参数\ConfigureEnv？

或者如何获得如下所示的预期结果

<statement>
<label>Proof</label>
<p class="noindent">Sample text</p>
</statement>

<statement>
<label>Proof of Theorem&#x00A0;1</label>
<p class="noindent">Sample text</p>
</statement>

我会将校样标签打印部分从环境中移出到独立命令，然后可以将其配置为打印您想要的<label>：

包裹myproof.sty

\ProvidesPackage{myproof}

\newcommand\printproof[1]{\def\arg{#1}\ifx\arg\empty\textit{Proof}\else\textit{#1}\fi:}
\newenvironment{proof}[1][]{\printproof{#1}\ \ignorespaces}
                          {} 


\endinput

配置文件myproof.4ht：

\NewConfigure{printproof}{2}

\pend:defI\printproof{\a:printproof}
\append:defI\printproof{\b:printproof}

\ConfigureEnv{proof}
         {\ifvmode \IgnorePar\fi \EndP\HCode{<statement>}\IgnoreIndent \ShowPar\par}
         {\ifvmode \IgnorePar\fi \EndP\HCode{</statement>}}
         {}{}

\Configure{printproof}{\ifvmode\IgnorePar\fi\EndP\HCode{<label>}\NoFonts}{\EndNoFonts\HCode{</label>}\par}

\endinput

首先，使用 定义两个用于插入标签的钩子，然后使用和命令\NewConfigure将它们插入到命令的开头和结尾。其余的只是标签的配置。...用于抑制元素中的斜体字体。\printproof\pend:defI\append:defI\NoFonts\EndNoFonts<label>

结果：

<statement>
   <label>Proof :</label>
<!--l. 6--><p class="indent" >    Sample text
</p></statement>
   <statement>
   <label>Proof of Theorem 1:</label>
<!--l. 9--><p class="indent" >    Sample text
</p></statement>
