使用 crossreftools 和 zref 包运行这些测试
\begin{document}
\section{foo bear}
\label{sec:foo}
This is dummy text.
\begin{equation}

\crtlistoflabels
{\textbackslash}crtcrefcounter\{sec:foo\} = \crtcrefcounter{sec:foo}
{\textbackslash}crtcrefnamebylabel \{sec:foo\} = \crtcrefnamebylabel{sec:foo}
{\textbackslash}crtcrefresult\{sec:foo\} = \crtcrefresult{sec:foo}
{\textbackslash}crtcrefresult\{sec:foo\} = \crtcrefresult{sec:foo}
counter=\zref@extractdefault {sec:foo} {counter} {error}
envname=\zref@extractdefault {sec:foo} {envname} {error}
{\textbackslash}ztitleref \{sec:foo\} = \ztitleref {sec:foo}
{\textbackslash}crtcrefcounter\{def:baz\} = \crtcrefcounter{def:baz}
{\textbackslash}crtcrefnamebylabel \{def:baz\} = \crtcrefnamebylabel{def:bazi}
{\textbackslash}crtcrefresult\{def:baz\} = \crtcrefresult{def:baz}
{\textbackslash}crtcrefresult\{def:baz\} = \crtcrefresult{def:baz}
counter=\zref@extractdefault {def:baz} {counter} {error}
envname=\zref@extractdefault {def:baz} {envname} {error}
{\textbackslash}ztitleref \{def:baz\} = \ztitleref {def:baz}
\makeatother
我明白了
\crtcrefcounter{sec:foo} = section
\crtcrefnamebylabel {sec:foo} = section
\crtcrefresult{sec:foo} =
\crtcrefresult{sec:foo} =
counter=error
envname=error
\ztitleref {sec:foo} = ??
\crtcrefcounter{def:baz} = theorem
\crtcrefnamebylabel {def:baz} = UNDEFINED LABEL
\crtcrefresult{def:baz} = 1
\crtcrefresult{def:baz} = 1
counter=error
envname=error
\ztitleref {def:baz} = ??
因此，似乎 cleveref 并未得到这两个软件包的完全支持。 \crtrefcounter 的输出足以满足我的当前需求，但我仍未在 crossreftools 或 zref 中找到与 \refname 等效的可行方法。
