Export Beamer notes content to a structured document

beamer add tag

JeT

**Context**

To shoot a video, I will use a `beamer` presentation (hence my previous [question](https://topanswers.xyz/tex?q=2029) about half frames... the other half is for me).

I am asked to provide a script with what I'll say. 

`notes` seem to be the correct tool for that.

However, I would also need (for subtitles) to provide a complete script.

**Where I need help**

I tried to export the content of each `note` to a `\jobname-mynotes.tex` file thanks to [`newfile` package](http://mirrors.ctan.org/macros/latex/contrib/newfile/newfile.pdf)

I am stuck on 3 points
1. a `beamer \newcommand` that mimic `\notes<>{}` but exports its contents
1. add the document `\section` and `\subsection` in the output document.
1. open and close the output after the dcument begins and before it ends. I suspect `etoolbox` to be involved, but I am lacking of practice on this package.

**What I've tried so far**

MWE

```
\documentclass{beamer}  
\usepackage{newfile}
\usepackage{lipsum}

\setbeameroption{show notes}
\setbeameroption{show notes on second screen=right}
%\setbeameroption{show only notes} 


\newcommand<>{\mynote}[1]{
	\note<#2->{%
		#1 % I still want to display the text in beamer
		\addtostream{mynotes}{#1} %and also want to export it
	}
}

\begin{document}

%Open the stream
\newoutputstream{mynotes}
\openoutputfile{\jobname-mynotes.tex}{mynotes}

\section{First section}
\subsection{First subsection}

\begin{frame}
	\begin{itemize}
		\item<1-> talk about something
		\item<2-> talk about other thing
	\end{itemize}
		
	\note<1>{\lipsum[1] \addtostream{mynotes}{\lipsum[1]}}
	\note<2>{Just some text, not command}
		
\end{frame}  
	
\subsection{Second subsection}
%% I get an error when I try to use \mynote
%\begin{frame}
%	\begin{itemize}
%		\item<1-> talk about something
%		%\pause
%		\item<2-> talk about other thing
%	\end{itemize}
%	
%	\mynote<1>{\lipsum[1]}
%	\mynote<2>{Just some text, not command}
%	
%\end{frame}  

\closeoutputstream{mynotes}
%close the stream

\end{document}

```

> 1. a beamer `\newcommand` that mimic `\notes<>{}` but exports its contents

If you only use notes inside the frame environment, you could add the stream to `\beamer@inframenote` and then just use the normal `\note` macro

(patching `\note` is a bit tricky because it is defined differently depending on the context)

> 2. add the document `\section` and `\subsection` in the output document.

You could use 

```
\AtBeginSection{\addtostream{mynotes}{\section{\secname}}}
\AtBeginSubsection{\addtostream{mynotes}{\subsection{\subsecname}}}
```

> 3. open and close the output after the document begins and before it ends. I suspect `etoolbox` to be involved, but I am lacking of practice on this package.

Indeed, etoolbox comes in handy for this:

```
\AtBeginDocument{\newoutputstream{mynotes}\openoutputfile{\jobname-mynotes.tex}{mynotes}}

\AtEndDocument{\closeoutputstream{mynotes}}
```
