参考列表环境标签未正确显示

Question

定义

\newcommand{\matref}[1]{%
\hyperref[#1]{\color{\mainColor}{Code {#1}}}%
}

不必要地复杂并且在逻辑上也是错误的。

此时显示的\hyperref[foo]{bar}标签虽然会有一个链接，但不会显示标签后面的引用。foobar

链接应该\ref与周围的组一起完成\color{...} \ref{}，以防止颜色变化的泄漏。

另一个严重的逻辑错误：\label不应在之后使用，而应作为中的lstlisting可选值，否则标签会抓取环境之外的最后一个命令的值，在本例中为。label=code:test[...]\@currentlabel\refstepcounterlstlistings\refstepcounter{section}

另一个更好的可能性：使用cleveref仅适用于 matlab 代码的专门列表环境或应用于\crefname{listing}{code}{codes}所有\Crefname{listing}{Code}{Codes}列表。

How come the reference here \matref{code:test} does not show up correctly?
