我正在尝试按章节划分定理列表，类似于这里。我正在使用该thmtools软件包，并且已经接近让它工作了。我使用了我发布的链接中的以下代码：
\documentclass[a4paper]{book}
\usepackage{amsthm,thmtools}
\usepackage{xcolor}
\usepackage{framed}
\colorlet{shadecolor}{lightgray!25}
\newtheorem{thm}{Theorem}[chapter]
\newtheoremstyle{definitionsty}{3pt}{3pt}{\slshape}{}{\bfseries}{.}{.5em}{}
\theoremstyle{definitionsty}
\newtheorem{tdefn}{Definition}[chapter]
\newenvironment{defn}
{\begin{shaded}\begin{tdefn}}
{\end{tdefn}\end{shaded}}
\usepackage{etoolbox}
\makeatletter
\patchcmd\thmtlo@chaptervspacehack
{\addtocontents{loe}{\protect\addvspace{10\p@}}}
{\addtocontents{loe}{\protect\thmlopatch@endchapter\protect\thmlopatch@chapter{\thechapter}}}
{}{}
\AtEndDocument{\addtocontents{loe}{\protect\thmlopatch@endchapter}}
\long\def\thmlopatch@chapter#1#2\thmlopatch@endchapter{%
\setbox\z@=\vbox{#2}%
\ifdim\ht\z@>\z@
\hbox{\bfseries\chaptername\ #1}\nobreak
#2
\addvspace{10\p@}
\fi
}
\def\thmlopatch@endchapter{}
\makeatother
\renewcommand{\thmtformatoptarg}[1]{ -- #1}
\renewcommand{\listtheoremname}{List of definitions}
\begin{document}
\frontmatter
\listoftheorems[ignoreall,show={tdefn}]
\mainmatter
\chapter{X}
\begin{defn}[My hilarious definition]
bla bla
\end{defn}
\chapter{Y}
\begin{thm}
b
\end{thm}
\chapter{Z}
\begin{defn}[My hilarious definition 2]
bla bla
\end{defn}
\begin{thm}
a
\end{thm}
\end{document}
此解决方案的唯一“问题”是我想要完整的章节名称，而不仅仅是章节编号。如何修改此代码才能实现此目的？我尝试过自己调整此代码，但无法使其正常工作。
答案1
将章节标题保存为\chaptertitle。
\documentclass[a4paper]{book}
\usepackage{amsthm,thmtools}
\usepackage{xcolor}
\usepackage{framed}
\colorlet{shadecolor}{lightgray!25}
\newtheorem{thm}{Theorem}[chapter]
\newtheoremstyle{definitionsty}{3pt}{3pt}{\slshape}{}{\bfseries}{.}{.5em}{}
\theoremstyle{definitionsty}
\newtheorem{tdefn}{Definition}[chapter]
\newenvironment{defn}
{\begin{shaded}\begin{tdefn}}
{\end{tdefn}\end{shaded}}
\usepackage{etoolbox}
\newcommand{\chaptertitle}{}% reserve global name
\makeatletter
\patchcmd{\@chapter}{\chaptermark{#1}}{\chaptermark{#1}\xdef\chaptertitle{#1}}{}{}
\patchcmd\thmtlo@chaptervspacehack
{\addtocontents{loe}{\protect\addvspace{10\p@}}}
{\addtocontents{loe}{\protect\thmlopatch@endchapter\protect\thmlopatch@chapter{\thechapter~\chaptertitle}}}
{}{}
\AtEndDocument{\addtocontents{loe}{\protect\thmlopatch@endchapter}}
\long\def\thmlopatch@chapter#1#2\thmlopatch@endchapter{%
\setbox\z@=\vbox{#2}%
\ifdim\ht\z@>\z@
\hbox{\bfseries\chaptername\ #1}\nobreak
#2
\addvspace{10\p@}
\fi
}
\def\thmlopatch@endchapter{}
\makeatother
\renewcommand{\thmtformatoptarg}[1]{ -- #1}
\renewcommand{\listtheoremname}{List of definitions}
\begin{document}
\frontmatter
\listoftheorems[ignoreall,show={tdefn}]
\mainmatter
\chapter{X}
\begin{defn}[My hilarious definition]
bla bla
\end{defn}
\chapter{Y}
\begin{thm}
b
\end{thm}
\chapter{Z}
\begin{defn}[My hilarious definition 2]
bla bla
\end{defn}
\begin{thm}
a
\end{thm}
\end{document}
此版本添加了每个章节，而不仅仅是包含定理的章节。
\documentclass[a4paper]{book}
\usepackage{amsthm,thmtools}
\usepackage{xcolor}
\usepackage{framed}
\colorlet{shadecolor}{lightgray!25}
\newtheorem{thm}{Theorem}[chapter]
\newtheoremstyle{definitionsty}{3pt}{3pt}{\slshape}{}{\bfseries}{.}{.5em}{}
\theoremstyle{definitionsty}
\newtheorem{tdefn}{Definition}[chapter]
\newenvironment{defn}
{\begin{shaded}\begin{tdefn}}
{\end{tdefn}\end{shaded}}
\usepackage{etoolbox}
\newcommand{\chaptertitle}{}% reserve global name
\makeatletter
\let\thmtlo@chaptervspacehack\relax
\patchcmd{\@chapter}{\chaptermark{#1}}{\chaptermark{#1}%
\addtocontents{loe}{\par\noindent\textbf{\@chapapp~\thechapter~#1}}}
{}{}
\makeatother
\renewcommand{\thmtformatoptarg}[1]{ -- #1}
\renewcommand{\listtheoremname}{List of definitions}
\begin{document}
\frontmatter
\listoftheorems[ignoreall,show={tdefn}]
\mainmatter
\chapter{X}
\begin{defn}[My hilarious definition]
bla bla
\end{defn}
\chapter{Y}
\begin{thm}
b
\end{thm}
\chapter{Z}
\begin{defn}[My hilarious definition 2]
bla bla
\end{defn}
\begin{thm}
a
\end{thm}
\end{document}
