不带书签\listsubseclocaltoc

我想创建本地目录，以分项列表的形式列出某一部分内的子部分。为此，我使用etoc并定义了相应的样式\etocsetstyle。

问题是，通过调用本地 toc \itemizedlocaltoc，我还通过调用全局设置了 ToC 深度\etocsettocdepth{subsection}。这会更改文档其余部分的书签深度：范围泄漏。

有没有办法限制的范围\etocsettocdepth{subsection}？

etoc.sty提及的相关部分\global似乎暗示“不”。

\def\etocsettocdepth   {\futurelet\Etoc@nexttoken\Etoc@set@tocdepth }
\def\Etoc@set@tocdepth {\ifx\Etoc@nexttoken\bgroup
                            \expandafter\Etoc@set@tocdepth@
                       \else\expandafter\Etoc@set@toctocdepth
                       \fi }
\def\Etoc@set@tocdepth@ #1{\@ifundefined {Etoc@#1@@}
      {\PackageWarning{etoc}
          {Unknown sectioning unit #1, \protect\etocsettocdepth\space ignored}}
{\global\c@tocdepth\csname Etoc@#1@@\endcsname}%

Touhami 提到\etocsetnexttocdepth，这解决了这个问题

定义\etocsetnexttocdepth

\def\etocsetnexttocdepth #1{%
    \@ifundefined{Etoc@#1@@}
     {\PackageWarning{etoc}
       {Unknown sectioning unit #1, \protect\etocsetnextocdepth\space ignored}}
     {\edef\Etoc@aftertochook {\global\c@tocdepth\the\c@tocdepth\space
                              \let\noexpand\Etoc@aftertochook\noexpand\@empty }%
      \global\c@tocdepth\csname Etoc@#1@@\endcsname}%
}%

此定义不同于，它添加了一个钩子，该钩子将在每个目录\etocsettocdepth之后执行。如上面的代码所示，在深度改变之前，将其设置为包含当前 ToC 深度的寄存器。etoc\edef\Etoc@aftertochook\c@tocdepth\c@tocdepth
