Beamer section numbers

Beamer section numbers

[thomas.hodgson-6DaNJ7gwbyQ]

[-- Attachment #1.1: Type: text/plain, Size: 1165 bytes --]

Since I updated to pandoc 2.0.4 my Beamer output prints the section or 
subsection number on section title frames; my Beamer version is 3.45 Here's 
a MWE:

```
# Section

## Subsection

### Frame

Foo
```

I would previously just see 'Section' and 'Subsection', now it is 
'1\nSection', '1\nSubsection'.

If the frames are numbered it would be better if they were 1, 1.1 etc.

However, wouldn't it be better to remove all the 
`\let\insertpartnumber\relax`, `\let\partname\relax`? And let the Beamer 
theme (and babel/polyglossia) handle the localisation and presentation of 
section titles?

Re: Beamer section numbers

[John MACFARLANE]

I can't reproduce this. I tried with your input, `pandoc -o
my.pdf -t beamer`.  I got a PDF with no section numbers.

Are you perhaps using a custom template?  (Check in
~./pandoc/templates as well.)  Did you use --toc on the
command line?

Thank you for looking at this.

This is my command:
pandoc -t beamer -o foo.pdf foo.md

I'm not using a custom template; I don't have a ~/.pandoc/templates 
directory.

Looking at the relevant code in Beamer here 
<https://github.com/josephwright/beamer/blob/ac6ea5eae32da4b80eb6a46cd62cb8aedd093c08/base/themes/inner/beamerinnerthemedefault.sty> 
I can't see why the current template doesn't do `\let\thepart\relax` 
instead. I did that in a custom template and that gives me the expected 
behaviour.

```
$if(section-titles)$
\AtBeginPart{
  \let\thepart\relax
  \let\partname\relax
  \frame{\partpage}
}
\AtBeginSection{
  \ifbibliography
  \else
    \let\thesection\relax
    \let\sectionname\relax
    \frame{\sectionpage}
  \fi
}
\AtBeginSubsection{
  \let\thesubsection\relax
  \let\subsectionname\relax
  \frame{\subsectionpage}
}
```

Maybe this changed in a recent version of Beamer? (I can't find any 
evidence of that, though.)

Re: Beamer section numbers

[John MACFARLANE]

Can you generate the tex file directly?

    pandoc -t beamer -s -o foo.tex foo.md

Then attach or include foo.tex so I can compare it with
what I have.  Also try compiling it with pdflatex to
verify that you still get the numbers.

If we get the same tex output from pandoc, but you get
the numbers in the PDF and I don't, it suggests a
change in beamer itself.

The tex output is attached. I still get numbers; I did latexmk -pdf foo.tex.

Re: Beamer section numbers

[John MACFARLANE]

I get exactly the same tex output.
When I do latexmk -pdf foo.tex, I don't get numbers.
So, could this be a change in beamer?

Re: Beamer section numbers

[thomas.hodgson-6DaNJ7gwbyQ]

[-- Attachment #1.1: Type: text/plain, Size: 6688 bytes --]

I'm on Beamer 3.45. Tthe latest on CTAN is 3.46 
<https://ctan.org/pkg/beamer>. That sounds like it. I saw a few commits in 
the Beamer repo which change relevant code, but I haven't tried to 
understand them yet.

I looked at the definitions of \partpage etc. They can be redefined using 
Beamer's template system. Here is a first go:

```
\setbeamertemplate{part page}{
\centering
\begin{beamercolorbox}[sep=16pt,center]{part title}
    \usebeamerfont{part title}\insertpart\par
\end{beamercolorbox}
}

\setbeamertemplate{section page}{
\centering
\begin{beamercolorbox}[sep=12pt,center]{part title}
    \usebeamerfont{section title}\insertsection\par
\end{beamercolorbox}
}

\setbeamertemplate{subsection page}{
\centering
\begin{beamercolorbox}[sep=8pt,center]{part title}
    \usebeamerfont{subsection title}\insertsubsection\par
\end{beamercolorbox}
}
```

The various \let and \relax can then be removed.

Re: Beamer section numbers

[thomas.hodgson-6DaNJ7gwbyQ]

[-- Attachment #1.1: Type: text/plain, Size: 7201 bytes --]

I asked on Stack Exchange, and learnt that Beamer has reverted the changes 
that cause the issue: https://tex.stackexchange.com/a/405123/451

The answer confirmed my method for altering the templates, but I haven't 
tested it with bibliographies yet.

Re: Beamer section numbers

[John MACFARLANE]

We need a revised template that works with both the older
version of beamer (e.g. the one I have in texlive, 3.41)
and newer ones.  Do you have a suggestion for that?
