如何在 beamer 中的幻灯片内创建一个命令，使其在当前幻灯片之后创建另一张幻灯片？

Question

所以，让我向您展示我的问题的 MWE。

\documentclass[serif, aspectratio=169,t]{beamer}
\usepackage[brazil]{babel}
\usepackage[no-math]{fontspec}
\usepackage{euler}
\setmainfont{Calibri}
\usepackage{lipsum}
\newcommand{\rascunhoem}[1]{{\usebackgroundtemplate{\includegraphics[width=\paperwidth, height = \paperheight]{imagens/image.pdf}}\begin{frame}{#1}\end{frame}}}
\newcommand{\questao}[1]{{\usebackgroundtemplate{\includegraphics[width=\paperwidth, height = \paperheight]{imagens/image.pdf}}\begin{frame}[allowframebreaks]#1\end{frame}}\rascunhoem{Rascunho}\rascunhoem{Rascunho}}

\begin{document}

\questao{\lipsum[1-2]\gab{Teste}\lipsum[3-5]}

\end{document}

如果您想测试它，我会在下面的链接中发送一个 PDF 模板图像供您编译：

幻灯片背景的 image.pdf 示例链接

所以，这就是我一直尝试但未取得多大成功的操作。如您所见，段落\gab{}之间有一个我尚未定义的命令lipsum。

我有很多具有这种配置的幻灯片块，其中第一段包含命令\gab{}（用于其他目的），然后是其后的幻灯片的其余部分。

我想\gab{}添加一张幻灯片后两张“Rascunho”幻灯片。例如，如果我创建：

\questao{Here's a text example before the command. \gab{This'll be added after the two ``Rascunho'' slides} Here's the text after. 
There's no way I can move the command to the end, I have to leave it here, since I have more than ten thousand blocks like this.}

因此，我想This'll be added after the two ``Rascunho'' slides使用\gab{}命令在两张“Rascunho”幻灯片之后创建一张带有文本的幻灯片。

再次，我无法更改命令在文本中的位置，也无法更改我呈现的结构。我只想\gab{}按照我要求的方式构建它。

您可以\gab定义另一个宏（此处\@gab），该宏在代码末尾使用\questao，例如

\documentclass[serif, aspectratio=169,t]{beamer}

\usepackage[brazil]{babel}

\newcommand{\rascunhoem}[1]{%
   \begingroup
   \usebackgroundtemplate{\includegraphics[width=\paperwidth,height=\paperheight]{example-image}}%
   \begin{frame}
   #1
   \end{frame}
   \endgroup
}

\makeatletter
\newcommand{\questao}[1]{%
   \begingroup
   \def\@gab{}%
   \def\gab##1{\@bsphack\gdef\@gab{##1}\@esphack}%
   \usebackgroundtemplate{\includegraphics[width=\paperwidth,height=\paperheight]{example-image}}%
   \begin{frame}[allowframebreaks]
   #1
   \end{frame}
   \rascunhoem{Rascunho}%
   \rascunhoem{Rascunho}%
   \ifx\@gab\@empty
      \def\next{\relax}%
   \else
      \def\next{\begin{frame}\@gab\end{frame}}
   \fi
   \next
   \endgroup
}
\makeatother

\begin{document}

\questao{Here's a text example before the command. \gab{This'll be added after
the two ``Rascunho'' slides} Here's the text after. There's no way I can move
the command to the end, I have to leave it here, since I have more than ten
thousand blocks like this.}

\end{document}

这不支持\gab在一次调用中多次出现\questao。
