The command --toc-depth doesn't change the depth (md->pdf)

Reproducible steps :

1. Create a file with the content:

---
title: Title
subtitle: Subtitle
lang: fr-FR
author: "Author"
theme: "Boadilla"
colortheme: "dolphin"
fonttheme: "structurebold"
aspectratio: 43
fontsize: 14pt
linkstyle: bold

Compile using :

pandoc -t beamer --toc-depth=5 --toc  <file.md> -o <file.pdf>

Output:
The toc slide is :

1. Section One
2. Section Two

Expected:
The toc slide should be:

1. Section One
   1.1. Subsection One
   1.2. Subsection Two
2. Section Two
   1.1. Subsection One
   1.2. Subsection Two

default latex template has:

$if(beamer)$
\begin{frame}[allowframebreaks]
$if(toc-title)$
  \frametitle{$toc-title$}
$endif$
  \tableofcontents[hideallsubsections]
\end{frame}
$else$
{
$if(colorlinks)$
\hypersetup{linkcolor=$if(toccolor)$$toccolor$$else$$endif$}
$endif$
\setcounter{tocdepth}{$toc-depth$}
\tableofcontents
}
$endif$

So, the \setcounter{tocdepth}{$toc-depth$} is only set for latex output, not for beamer.
For beamer, we have the [hideallsubsections] option hard-coded.

I can't remember the rationale, if any, for these decisions.

[jgm]

One important thing to note: in your example, slide level = 2 (see the manual for this concept). That means that the level-2 headings do not create subsections; they create slides. So, even remove [hideallsubsections], you'd only get the top level in your toc.

Perhaps a better test case is

I think I'll change this so it uses toc-depth like the regular LaTeX template.

[Thanatos0173]

So, just to be sure, I can't change the way the toc is generated because I'm using beamer ? Or do I need to change the default latex template to be able to show more information in the toc ?

[jgm]

You'd have to change the latex template, yes. The commit noted above does this, so you can just grab the new template from there.

[Thanatos0173]

Ok, thank you very much !

[NMarkgraf]

Bad fix! This breaks all my coding, because I do not want subsections in toc. Beamer does not care about toc-dept. - So this might be a bad solution.

[jgm]

@NMarkgraf can you elaborate? Setting toc-depth has no effect in beamer?

[jgm]

@NMarkgraf In my tests, --toc-depth seems to work properly with beamer. If you think this is not the case, please give full instructions for reproducing the issue.
