autoref、titleclass 和 titlesec——显示父级和子级计数器

Question

我想为工作包 (WP) 实现一个新的标题类，并为子工作包实现一个嵌套的标题子类。两者的工作方式应类似于\section和\subsection，即当工作包计数器增加时，子工作包计数器会重置。

为了实现这一点，我使用了\titleclasstitlesec 包的命令以及相应的\newcounter命令。然而，问题是，当我引用子工作包带有 autoref，则只会显示子工作包的计数器。但是，我想要父工作包的计数器，后跟“。”，然后是子工作包的计数器，就像部分和子部分一样。

例如，如果wp:sub2test是第一个父工作包中的第二个子工作包的标签，\autoref{wp:sub2test}则应显示“WP 1.2”。但是，正如您在我的 MWE 中看到的那样，它显示“WP 2”。我该如何解决这个问题，即，我该如何告诉 autoref 吐出父计数器，然后是一个点，然后是子计数器？

\workpackage{test}

\subworkpackage{sub2test}
\label{wp:sub2test}
some subwp

\section{Referring to WP with autoref}
\label{sec:sec}
This gives \autoref{wp:test} and \autoref{wp:sub1test} and \autoref{wp:sub2test}, but it should give WP 1 and WP 1.1 and WP 1.2.
\end{document}

Answer 1

是subworkpackage的“子”级别workpackage，而不是 的\section，因此必须使用\workpackage作为“父”级别，而不是\section，否则所有计数器信息都将是错误的，参考标签也是如此！

\titleclass{\subworkpackage}{straight}[\workpackage]
