将内容放入附录的宏

Question

我正在尝试编写一个宏，通过设置变量将定理证明放入和移出附录。

我知道如何执行以下操作：在下面的示例中，当我将变量 appendixenabled 设置为 1 时，校样将转到新部分（第 2 部分）。此外，如果将其设置为 0，则校样是内联的。

\documentclass{article}[11pt]

\usepackage{amsthm, amsmath}
\usepackage{cleveref}
\usepackage[appendix=append]{apxproof}
\usepackage{thmtools, mathtools, thm-restate}\newtheorem*{theorem*}{Theorem}
\newtheorem{fact}{Fact}[section]
\newtheorem{lemma}{Lemma}[section]
\newtheorem{theorem}[lemma]{Theorem}
\renewenvironment{proof}{\smallskip\noindent{\bf Proof:}}%
        {\hspace*{\fill}\par}


% =========================================================
%                       Appendix stuff
% =========================================================
\newcommand{\myproof}[4]{
% 1: name of the environment
% 2: command 
% 3: label  of the theorem
% 4: proof
    \begin{proof}
        #4  
    \end{proof}
}
\def\appendixenabled{1}
% Switch to 0 to make the proofs inline
\if\appendixenabled1
    \renewcommand{\myproof}[4]{
    The proof is provided in Appendix~\ref{sec:proofof#3}
    \section{Proof of #1~\ref{#3}}
        \label{sec:proofof#3}
        \begin{proof}
            #4  
        \end{proof}
    }
\fi
% =========================================================

\begin{document}
\section{One}

\begin{restatable}{theorem}{aaa}
    \label{thmLabel}
    This is a resettable theorem!
\end{restatable}



\myproof{Theorem}{aaa}{thmLabel}{This is the proof.}
\end{document}

相反，我需要将 proof 移至文档末尾的附录部分。但是，如果我按如下方式添加 toappendix 环境（在 apxproof 包中），则会出现编译错误。有什么想法吗？

\if\appendixenabled1
    \renewcommand{\myproof}[4]{
    \begin{toappendix}
        The proof is provided in Appendix~\ref{sec:proofof#3}
        \section{Proof of #1~\ref{#3}}
        \label{sec:proofof#3}
        \begin{proof}
            #4  
        \end{proof}
    \end{toappendix}
    }
\fi

错误：

! FancyVerb Error:
  Extraneous input `The proof is provided in Appendix~\ref {sec:proofofthmLabel} \section {Proof of Theorem~\ref {thmLabel}} \label {sec:proofofthmLabel} \begin {proof} This is the proof. \end {proof} \end {toappendix} \end{document}' between \begin{toappendix}[<key=value>] and line end
.

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.
