我正在尝试minitoc通过更改标题来定制生成的目录，以便不让我的书周围有太多的“目录”页面。
但是，当我尝试使用\mtcsettitle引用时，会出现最奇怪的错误；特别是，我试图实现这样的目标：
\mtcsettitle{parttoc}{\ref{somepartref} -- \nameref{somepartref}}
这里出现了一个 MWE，尽管出现了错误，但至少\ref命令被正确接受了：
% !TEX program = lualatex
% !TeX encoding = UTF-8
% !TeX spellcheck = en_GB

This is some sort of joke introduction, for demo purposes only.

错误如下：

of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

This kind of error happens when you say `\if...' and forget
the matching `\fi'. I've inserted a `\fi'; this might work.

I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.

所以，我不确定我是否实际上不能在\mtcsettitle命令中使用引用，或者我是否缺少一些更大的图景。
