是什么导致我的类数组宏被污染

以下 MWE 是我的项目的简化版本。\CreateMacro用于创建表示词汇表的宏。例如，使用 body\CreateMacro{Newton}{$F=ma$}创建。调用将打印其主体并插入类似数组的宏。\Newton$F=ma$\Newton\Newton\pushed

\Einstein例如，如果我们已经创建了，并调用了\Einstein，那么\Einstein也将插入到中\pushed。

调用\Render将使所有元素变为\pushed空\pushed。

但是，我注意到有时\pushed会受到污染，如以下输出所示。我不明白为什么\Newton第九项仍然存在。第九项 \Newton不应该在那里。这似乎是由竞争条件引起的。你能找出并修复它吗？

该\Newton宏被传递给\leftmark，因为它出现在章节标题中，所以在打印标题时对其进行评估并执行推送。

你必须消除这种行为。如果你打算做目录，也需要类似的消除。

\documentclass{book}

\newcommand\Format[1]{%
    \begin{tcolorbox}%

\newenvironment{Table}

一个可能更强大的补丁是使和执行时\push相等。\@gobble\@starttoc\@outputpage

\documentclass{book}

\usepackage{xcolor}
\usepackage{etoolbox}
\usepackage[many]{tcolorbox}
\usepackage{environ}
\usepackage{xparse}

\makeatletter
\patchcmd{\@starttoc}{\begingroup}{\begingroup\let\push\@gobble}{}{}
\patchcmd{\@outputpage}{\begingroup}{\begingroup\let\push\@gobble}{}{}
\makeatother

\newcommand\Format[1]{%
    \begin{tcolorbox}%
        \textcolor{red}{#1}%
    \end{tcolorbox}%
}

\newenvironment{Table}
{\begin{tcbraster}[%
        raster height=\textwidth,
        raster width=\linewidth,
        raster columns=2,
        raster rows=4,
        boxrule=2pt,
        raster column skip=-2pt,
        raster row skip=-2pt,
]}
{\end{tcbraster}}

\newcommand\CreateMacro[2]{%
  \expandafter\newrobustcmd\csname#1\endcsname{#2\push{\Format{#2}}}%
}

\newcommand\push[1]{\gappto\pushed{#1}}

\newcommand\Render{%
    \begin{Table}
        \pushed
    \end{Table}%
    \gdef\pushed{}%
}

然而，在我看来，最好的做法是完全避免在标题中使用此类宏；在接下来的代码中，\CreateMacro{Newton}{$F=ma$}定义也要\Newton*在标题中使用，并且应该\pushNewton在更安全的时候使用。

\documentclass{book}

\usepackage{xcolor}
\usepackage{etoolbox}
\usepackage[many]{tcolorbox}
\usepackage{environ}
\usepackage{xparse}
\usepackage{atbegshi}

\newcommand\Format[1]{%
    \begin{tcolorbox}%
        \textcolor{red}{#1}%
    \end{tcolorbox}%
}

\newenvironment{Table}
{\begin{tcbraster}[%
        raster height=\textwidth,
        raster width=\linewidth,
        raster columns=2,
        raster rows=4,
        boxrule=2pt,
        raster column skip=-2pt,
        raster row skip=-2pt,
]}
{\end{tcbraster}}

\makeatletter
\newcommand\CreateMacro[2]{%
  \expandafter\newrobustcmd\csname#1\endcsname{%
    \@ifstar{\@nameuse{#1star}}{\@nameuse{#1nostar}}%
  }%
  \@namedef{#1nostar}{#2\push{\Format{#2}}}%
  \@namedef{#1star}{#2}% \global\toggletrue{#1}}%
  \@namedef{push#1}{\push{\Format{#2}}}%
}
\makeatother

\newcommand\push[1]{\gappto\pushed{#1}}

\newcommand\Render{%
    \begin{Table}
        \pushed
    \end{Table}%
    \gdef\pushed{}%
}
