Beamer 模式和输入

tag-icon • tag-icon beamer input mode
Beamer 模式和输入

这是 MWE

\documentclass{beamer}


\begin{document}
    \mode*
    
    \mode<all>{
    
    \input{input1.tex}
    
    \input{input2.tex}
    
    }
\end{document}

令人惊讶的是，输入的第二个文件没有被编译。为什么会这样？修改

\mode<all>{ \input{input1.tex} }

\mode<all>{ \input{input2.tex} }

似乎有效，但我发现以前的想法不起作用，这有点令人惊讶。

现在，在 samcarter_is_at_topanswers.xyz 回复后，我更加困惑了。对以下内容的编辑也有效：

\documentclass{beamer}


\begin{document}
    \mode*
    
    \mode<all>
    
    \input{input1.tex}
    
    \input{input2.tex}
    
    
\end{document}

因此，删除后，{}即使没有 samcarter_is_at_topanswers.xyz 建议的makeatlatter-extension，它也能正常工作。为什么会这样？这是真的吗？因为命令\mode不能用括号限制在代码中的特定区域？

就像一个学术练习，你可以将模式\input中不被忽略的宏添加到列表中ignorenonframetext，然后你会得到第二帧（小心，这可能会导致某种问题，因为对 beamer 的类似更改已被恢复 https://github.com/josephwright/beamer/commit/0701322e7399290768a1c1a73c72960f7745dec3)：

\documentclass{beamer}


\begin{filecontents*}[overwrite]{input1.tex}
\begin{frame}
1
\end{frame}
\end{filecontents*}

\begin{filecontents*}[overwrite]{input2.tex}
\begin{frame}
2
\end{frame}
\end{filecontents*}
