修补后（手动，即直接编辑回忆录的代码），如下所示：
它看起来应该是这样的：
我尝试使用 修补回忆录xpatch。我做的这个补丁如果能找到正确的代码就会起作用，但xpatch它说找不到要修补的代码：
\documentclass[
12pt,
]{abntex2} % memoir is loaded internally by the `abntex2` class
\usepackage{xpatch}
\makeatletter
\newcommand{\chapternumberlineappendixpatch}[1]{%
\chapternumberlinehook{#1}%
\chapternumberlinebox\@tempdima{\@chapapp@head\@cftbsnum #1~~\@cftasnum~~}%
\@cftasnumb~}%
\patchcmd{\@chapter}{%
\addcontentsline{toc}{appendix}{\protect\chapternumberline{\thechapter}\f@rtoc}
}{}{\addcontentsline{toc}
{appendix}{\protect\chapternumberlineappendixpatch{\thechapter}\f@rtoc}}{
\message{Chapterformat patch for chapternumberline could NOT
be applied because its code was not found!^^J ^^J^^J^^J^^J^^J^^J^^J^^J^^J^^J}
\xshowcmd\@chapter
}
\makeatother
\begin{document}
\tableofcontents
\chapter{Some}
\begin{apendicesenv}
\chapter{Other}
\end{apendicesenv}
\end{document}
这是memoir代码：
File: memoir.cls
2926: \ifanappendix
2927: \addcontentsline{toc}{appendix}{%
2928: \protect\chapternumberline{\thechapter}\f@rtoc}%
2929: \memappchapinfo{\thechapter}{\f@rtoc}{\f@rhdr}{#2}%
2930: \else
它应该停止调用该函数\chapternumberline并调用我的自定义\chapternumberlineappendixpatch函数并增加连字符周围的空间：
\newcommand{\chapternumberlineappendixpatch}[1]{%
\chapternumberlinehook{#1}%
\chapternumberlinebox\@tempdima{\@chapapp@head\@cftbsnum #1~~\@cftasnum~~}%
\@cftasnumb~}%
File: memoir.cls
2926: \ifanappendix
2927: \addcontentsline{toc}{appendix}{%
2928: \protect\chapternumberlineappendixpatch{\thechapter}\f@rtoc}%
2929: \memappchapinfo{\thechapter}{\f@rtoc}{\f@rhdr}{#2}%
2930: \else
答案1
我通过修补较小的碎片设法做到了这一点：
\documentclass[12pt,]{abntex2} % memoir is loaded internally by the `abntex2` class
\usepackage{xpatch}
\makeatletter
\xpretocmd{\l@appendix}{\def\@chapapp@extrahyphenspaces{~}}
{\message{^^J^^JChapterformat patch 1 for chapternumberline could SUCCESSFULLY!^^J}}
{\message{^^J^^JChapterformat patch 1 for chapternumberline could NOT be applied!^^J}}
\xpretocmd{\l@chapter}{\def\@chapapp@extrahyphenspaces{}}
{\message{^^J^^JChapterformat patch 2 for chapternumberline could SUCCESSFULLY!^^J}}
{\message{^^J^^JChapterformat patch 2 for chapternumberline could NOT be applied!^^J}}
\patchcmd{\chapternumberline}{\@cftasnum}{%
\@chapapp@extrahyphenspaces%
\@chapapp@extrahyphenspaces%
\@cftasnum%
}
{\message{^^J^^JChapterformat patch 3 for chapternumberline could SUCCESSFULLY!^^J}}
{\message{^^J^^JChapterformat patch 3 for chapternumberline could NOT be applied!^^J}}
\patchcmd{\chapternumberline}{\@cftasnumb}{%
\@cftasnumb%
\@chapapp@extrahyphenspaces%
\@chapapp@extrahyphenspaces%
}
{\message{^^J^^JChapterformat patch 4 for chapternumberline could SUCCESSFULLY!^^J}}
{\message{^^J^^JChapterformat patch 4 for chapternumberline could NOT be applied!^^J}}
\makeatother
\begin{document}
\tableofcontents
\chapter{Some}
\begin{apendicesenv}
\chapter{Other}
\end{apendicesenv}
\end{document}
