我正在使用tasks（作为的子集exsheets）来创建环境exer2和，exer3它们将微积分练习册中的练习集组织成行和列。我还使用环境exsheets和question来solution跟踪解决方案并有序地打印出来。
我知道第一级 {enumerate} 计数器的名称enumi如序言第 9 行所示。我不知道由 创建的环境中计数器的名称tasks。当我使用手册第 7.6 节第 13-14 页建议的语法时exsheets，我得到的是文本回显“tsk[a]”，而不是计数器。
我可以处理标签的最终格式solutions，我只需要知道如何获取“a，b，c”而不是“1 tsk [a]，1 tsk [a]，1 tsk [a]”。
我在这里遗漏了什么？

答案1
你使用的tasks方式我从未想象过……
您必须让模式读取器tasks知道计数器（实际上是一个内部 expl3 整数）exsheets：
\usepackage{exsheets,tasks}
\ExplSyntaxOn
\AddCounterPattern* [exsheets] {task} {tsk}
\ReadCounterFrom [exsheets] {task} \g__tasks_int
\ExplSyntaxOff
嵌入到您的示例文档中：
\documentclass{book}
\usepackage[inline]{enumitem}
\usepackage{exsheets,tasks}
\ExplSyntaxOn
\AddCounterPattern*[exsheets]{task}{tsk}
\ReadCounterFrom [exsheets]{task}\g__tasks_int
\ExplSyntaxOff
\SetupExSheets{
question/pre-hook = \vspace{-24pt},
question/post-hook = \vspace{-12pt},
question/headings = block ,
solution/headings = runin ,
solution/post-hook = \par \hrule \vspace{6pt} ,
counter-format=\arabic{enumi}~tsk[a]
}
\NewTasks[
before-skip=6pt,
after-skip=6pt,
after-item-skip=0pt,
item-indent=24pt,
label-width=6pt,
label-offset=12pt,
counter-format=tsk[a].~]{exer3}[\exercise](3)
\NewTasks[

\end{solution}
\exercise
\begin{question}

\end{question}
\begin{solution}

\end{solution}
\end{exer3}
\end{enumerate}
\begin{enumerate}[resume]
\item Second exercise set.
\begin{exer2}

\end{question}
\begin{solution}

答案2
我无法让它发挥作用，但在阅读论坛上的其他一些帖子后，我确实找到了不同的答案
\usepackage{etoolbox}
\AtBeginEnvironment{exer2}{\setcounter{question}{0}}
\AtBeginEnvironment{exer3}{\setcounter{question}{0}}
\SetupExSheets{counter-format=\arabic{enumi}.\alph{question}}
似乎正在起作用。
