我看到的第一篇告诉我有关restatable环境的帖子：回顾一个定理。关于这样的事情，人们提出了几个问题：建立可重述的盒子定理说使用\declaretheoremstyle；在自定义环境中使用 restatable使用起来没问题\newenvironment，但会弄乱计数器。两者似乎都与我的定理颜色盒不太兼容：
\newtcbtheorem[number within=section]{mylemma}{Lemma}%
{colframe=blue!45!white,enlarge top by=0.15cm,before
skip=3pt,after skip=6.5pt,fonttitle=\slshape,breakable}{lem}
通常我可以通过以下方式使用这个环境
\begin{mylemma}{Lemma Name}{lemmalabel}
...
\end{mylemma}
（最后一个参数是标签）。以下是回顾一个定理我天真地写了以下代码：
\documentclass{article}
\usepackage{amsmath}
\usepackage{tcolorbox}
\tcbuselibrary{theorems}
\tcbuselibrary{breakable}
\usepackage[colorlinks = true, urlcolor = red]{hyperref}
\newtcbtheorem[number within=section]{mylemma}{Lemma}%
{colframe=blue!45!white,enlarge top by=0.15cm,before
skip=3pt,after skip=6.5pt,fonttitle=\slshape,breakable}{lem}
\usepackage{thmtools}
\declaretheorem[name=Theorem,numberwithin=section]{thm}
\begin{document}
\begin{mylemma}{Substitution lemma}{substitution}
Lemma in a tcolorbox
\end{mylemma}
\begin{restatable}{thm}{thmlabel}
Restatable theorem with thmtools
\end{restatable}
Theorem restated: \thmlabel*
\begin{restatable}{mylemma}{lemmalabel}
Restatable lemma in a tcolorbox
\end{restatable}
Lemma restated: \lemmalabel*
Reference to the lemma \ref{lem:substitution}
\end{document}
但这不起作用（如果删除尝试，它确实有效\begin{restatable}{mylemma}...）。是否可以调整restatable（和restatable*）环境以允许以下用法：
\begin{restatable}{mylemma}{Lemma Name}{lemmalabel}
...
\end{restatable}
\lemmalabel*
Lemma \ref{lem:lemmalabel}
生产两份相同的mylemma？
附注（由 CarLaTeX 解决，方法是thmtools将\newtcbtheorem) 当我在玩这个包时，thmtools我注意到我的定义的一些引用指向了错误的页面（例如它会显示 Def. 2.8 然后链接到 Def. 1.8）。我提供了一个 MWE：
\documentclass{article}
\usepackage{amsmath}
\usepackage{tcolorbox}
\tcbuselibrary{theorems}
\tcbuselibrary{breakable}
\usepackage[colorlinks = true, urlcolor = red]{hyperref}
\usepackage{thmtools}
\newtcbtheorem[number within=section]{mydef}{Definition}%
{colframe=red!65!black,enlarge top by=0.15cm,before
skip=3pt,after skip=6.5pt,fonttitle=\slshape,breakable}{def}
\begin{document}
\section*{220A Class Notes}
\section{Lecture 1}
\subsection{9/26/22 Class 2}
\begin{mydef}{Height of term}{term-height}
\end{mydef}
\begin{mydef}{Atomic formulas}{atomic-formula}
\end{mydef}
\begin{mydef}{Formulas}{formula}
\end{mydef}
\newpage
\section{Lecture 2}
\subsection{9/28/22 Class 3}
\begin{mydef}{Tarski's definition of truth/formula satisfaction}{tarski-truth}
\end{mydef}
\subsection{9/30/22 Class 4}
\begin{mydef}{Formulas as functions, notation}{formula-function-notation}
...
\end{mydef}
\newpage
\section{Lecture 3}
Definition \ref{def:formula-function-notation}
\end{document}
这似乎是一个已知问题：如果使用 thmtools，pageref 会出现错误页面但是答案描述的修复（放在\label某个位置）不适用于，\newtcbtheorem因为标签是隐式放置的，tcbtheorem而不是由用户明确放置的。
答案1
尝试一下这个：
\documentclass{article}
\usepackage{amsmath}
\usepackage{tcolorbox}
\tcbuselibrary{theorems}
\tcbuselibrary{magazine}% also load breakable
%\tcbuselibrary{breakable}
\usepackage[colorlinks = true, urlcolor = red]{hyperref}
\newtcbtheorem[number within=section]{mylemma}{Lemma}%
{colframe=blue!45!white,enlarge top by=0.15cm,before
skip=3pt,after skip=6.5pt,fonttitle=\slshape,breakable}{lem}
\newcommand{\myrecall}[2][1]{\par\noindent\useboxarray[#2]{#1}}
\usepackage{environ}
\NewEnviron{restatlemma}[2]{%
\newboxarray{#2}%
\begin{mylemma}[reset box array=#2, store to box array=#2]{#1}{#2}
\BODY%
\end{mylemma}%
\myrecall{#2}%
}
\usepackage{thmtools}
\declaretheorem[name=Theorem,numberwithin=section]{thm}
\begin{document}
\begin{mylemma}{Substitution lemma}{substitution}
Lemma in a tcolorbox
\end{mylemma}
\begin{restatable}{thm}{thmlabel}
Restatable theorem with thmtools
\end{restatable}
Theorem restated: \thmlabel*
\begin{restatlemma}{My Title}{lemmalabel}
Lemma stored in a tcolorbox
\end{restatlemma}
Lemma restated: \myrecall{lemmalabel}
Reference to the lemma \ref{lem:substitution}
\end{document}
