heading numbering in LaTeX export?

[Peter Salazar]

[-- Attachment #1: Type: text/plain, Size: 1010 bytes --]

I have a LaTeX template I created for use with org-mode, to export to PDF
via LaTeX using xelatex.

I don't edit LaTeX directly, I just generate from org-mode. This works
perfectly for me except for one thing: it only works when I have heading
numbering turned on.

When I turn numbering off in org-mode, by adding this line to my org-mode
file...

    #+OPTIONS:   num:nil

...LaTeX no longer recognizes my headings as headings. This creates two
problems:

1. The Table of Contents is blank.
2. The \leftmark in the heading shows up as "Contents" instead of showing
up as the title of the section.

How do I modify these org-mode preferences such that my I can turn heading
numbering off in org-mode while still correctly generating a Table of
Contents and adding my section title to the header?

I'm sorry, but I don't know enough about LaTeX to make a minimum
representation of this. I have no idea where the problem is.

Here are the org-mode preferences in question:

At the very least, can you provide a minimal org file? This is over my
head with xelatex and all that customization, but I think people are
going to at least need:
- minimal emacs config (reproducible version that produces the
problem, not just the latex stuff)
- a .org file that produces the issue you're experiencing (even with
just a couple headlines and the words "blah blah blah" or what have
you as the text

This is because, when you set num:nil, Org exports headings to LaTeX
using the \section*{} command, not the usual \section{}.  LaTeX does not
put sections defined with \section* (or \chapter*, \part*, etc.) in the
table of contents. 

Thus, if you still want all sections to show up in your table of
contents, you probably don't want to set num:nil.  If you just want
section numbers not to show up in section titles, there's probably a
simple way to do this in LaTeX by redefining a command, but I can't find
it right now; maybe someone else here knows.  Once you know the LaTeX
command, you can set it on Org via

#+LATEX_HEADER: \renewcommand{...}

or whatever.

I'm not sure about this issue.  I would guess that it's also caused
by using \section* rather than \section, but there's no \leftmark
command in the test document I created.

Thanks for the responses!

John: Oh yes, of course. Sorry about that. inimal org file and config files
are here. I had to make the org file long enough to make several pages, so
the header displays. Here you go:
https://github.com/petersalazar/org-troubleshooting

Rasmus: #+OPTIONS: num:0 is what I started from. When I do that, the
resulting PDF has no Table of Contents, and the header displays the section
title as "Contents."

The same thing happens with #+LATEX: \setcounter{secnumdepth}{0}.

Richard: Your idea about
#+LATEX_HEADER: \renewcommand{...}

sounds very promising! I'd love to know what the exact command is!

I don't need section numbers ever, so my desire is to turn off numbering
forever, but still have an intact Table of Contents and header.

Thanks guys!

The quick-and-dirty solution is

--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \renewcommand{\thesection}{}
#+LATEX_HEADER: \renewcommand{\thesubsection}{}
#+LATEX_HEADER: \renewcommand{\thesubsubsection}{}
--8<---------------cut here---------------end--------------->8---

That's enough for the default secnumdepth of 3, but if you make that
bigger, you'll have to make it even dirtier:

--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \renewcommand{\theparagraph}{}
#+LATEX_HEADER: \renewcommand{\thesubparagraph}{}
--8<---------------cut here---------------end--------------->8---

There is probably a cleaner way, but that would require cleverness
and I don't have any right now.

BTW, this turns off section numbers in the TOC as well, not just in the
body of the document.

Thank you! That solution is very promising indeed.

I see why it's quick and dirty though - it appears to be generation section
numbers, but just making the numbers invisible, so that the headings are
not flush with the left margin:

Is there a solution to that, or is that just the way it is?

Thanks again.

Here is a cleaner way:

#+LATEX_HEADER: \setcounter{secnumdepth}{0}
#+LATEX_HEADER: \setcounter{tocdepth}{3}

That appears to work perfectly. Thank you so much!

If I have 5 levels of heading, should I do it like this?

#+LATEX_HEADER: \setcounter{secnumdepth}{0}
#+LATEX_HEADER: \setcounter{tocdepth}{5}

Yes, although IMO the TOC will be too busy with that many levels.
But to each his/her own...

Hi Peter,


Actually, I hadn't understood your issue. I thought you weren't
getting headlines exported at all, as in a blank document, which might
require a bit more delving into. Now I get it and it makes sense. When
I use num:nil but want a TOC, I tend to just add the entries manually:

#+begin_example

* Introduction
\addcontentsline{toc}{subsection}{Introduction}

blah blah blah

* Conclusion
\addcontentsline{toc}{subsection}{Conclusion}

blah blah blah

#+end_example


Perhaps a bit manual, and it looks like you've gotten more automated
answers to use via #+latex_header arguments.


Good luck!
John

Ah, I see. Cool, then I will stick to {tocdepth}{3}. Thanks again!
