重置每个部分的 TotalCount (totcount)

Question

我正在尝试建立一个系统，其中我可以为每个部分计算总数并打印，然后重置每个部分。

梅威瑟：

\documentclass{article}

\usepackage{xparse}
\usepackage{ifthen}
\usepackage{totcount}

\newcounter{myCounter}[section]
\regtotcounter{myCounter}

\begin{document}

\section{sec1}
    \label{sec:sec1}

    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\

\section{sec2}
    \label{sec:sec2}

    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\total{myCounter}\\

\end{document}

生成：

1 sec1
1/6
2/6
3/6
4/6

2 sec2
1/6
2/6
3/6
4/6
5/6
6/6

期望结果：

1 sec1
1/4
2/4
3/4
4/4

2 sec2
1/6
2/6
3/6
4/6
5/6
6/6

我曾尝试过，\regtotcounter{myCounter}但没有成功。

您无法使用 来做到这一点totcount。也许可以使用xassoccnt，但它已无人维护。

这是一个独立的解决方案，其中每个部分的变化都会在文件中写出一些内容.aux（并且\AtEndDocument）：对于每个注册的计数器，其最终值与当前部分编号相关联。

因此我们能够在下次运行时知道每个部分的总数。

\documentclass{article}

\AddToHook{cmd/section/before}{\savesectioncounters}
\AtEndDocument{\savesectioncounters}

\ExplSyntaxOn

\clist_new:N \g__panda_counters_clist
\prop_new:N \g__panda_counters_prop

\AtBeginDocument{\prop_show:N \g__panda_counters_prop}

\NewDocumentCommand{\declaresectioncounter}{m}
 {
  \clist_gput_right:Nn \g__panda_counters_clist { #1 }
 }


\NewDocumentCommand{\savesectioncounters}{}
 {
  \clist_map_inline:Nn \g__panda_counters_clist
   {
    \iow_shipout:cx { @mainaux } { \sectioncountertotal{##1}{\use:c{the##1}}{\arabic{section}} }
   }
 }

\NewDocumentCommand{\sectioncountertotal}{mmm}
 {
  \prop_gput:Nnn \g__panda_counters_prop { #1@#3 } { #2 }
 }

\NewExpandableDocumentCommand{\getsectiontotal}{m}
 {
  \prop_item:Ne \g__panda_counters_prop { #1@\arabic{section} }
 }
\cs_generate_variant:Nn \prop_item:Nn { Ne }

\ExplSyntaxOff

\newcounter{myCounter}[section]
\declaresectioncounter{myCounter}

\begin{document}

    \stepcounter{myCounter}\themyCounter/\getsectiontotal{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\getsectiontotal{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\getsectiontotal{myCounter}

\section{sec2}
    \label{sec:sec2}

    \stepcounter{myCounter}\themyCounter/\getsectiontotal{myCounter}\\
    \stepcounter{myCounter}\themyCounter/\getsectiontotal{myCounter}\\

    \stepcounter{myCounter}\themyCounter/\getsectiontotal{myCounter}\\
