Problems exporting to-md since org-9.7.x

[antoniocorbi]

Actual Behavior

Since the org update from 9.6.x to 9.7.x org-hugo-export-to-md gives me some problems.

An org-file like:

:CONFIG:
#+startup: overview
#+setupfile: ./hugo.config
# +hugo_section: /
:END:
#+title: Avisos.
#+DESCRIPTION: Programación-II. Avisos.

* 2024.06.20 (C4)

Información para el examen de teoría y de prácticas de la convocatoria
C4 del próximo 12 de julio

* 2024.06.03 (C3)

Información para el examen de prácticas de la convocatoria C3 del
próximo 11 de junio

with this "hugo.config"

#+hugo_base_dir: ../
#+hugo_weight: auto
#+hugo_auto_set-lastmod: t
#+hugo_section:
#+OPTIONS: toc:2 num:t

Produces this markdown file:

+++
title = "Avisos."
description = "Programación-II. Avisos."
draft = false
+++

<div class="ox-hugo-toc toc has-section-numbers">

<div class="heading">Table of Contents</div>

- <span class="section-num">1</span> [2024.06.20 (C4)](#2024-dot-06-dot-20--c4)
- <span class="section-num">2</span> [2024.06.03 (C3)](#2024-dot-06-dot-03--c3)
- <span class="section-num">3</span> [2024.04.24](#2024-dot-04-dot-24)

</div>
<!--endtoc-->

As you can see it only has the table of contents but none of the real contents of the file.

Expected Behavior

Produce a markdown file with all the contents of the org file.

How to Reproduce the Issue

Upgrade to any org-9.7.x version.
Also downgrading to org-9.6.x make ox-hugo work again.

Can confirm this.

None of the headings and their contents are exported. However, no changes in the Org changelog strike me with suspicion. Debugging didn't show any obvious errors. Seems like some internals were changed, but not mentioned on the changelog.

[antoniocorbi]

For me it's becoming a showstoper as I want to use latest org (9.7.x).
In a week or so I'll decide what to do as weeks pass and this problem remains.

[andreyorst]

@antoniocorbi, a fellow Org maintainer recommended recompiling ox-hugo after updating Org. I've just tried it and it seems to work for me now with 9.7.7

[antoniocorbi]

Hi @andreyorst !
I removed all the *.elc files in ox-hugo, updated to org-9.7.7 and it seems to work!
How did you recompile the ox-hugo *.el files? I've tried with byte-recompile-directory and others and it seems I can't.
Meanwhile I'll stick to the .el files :)

I just wiped the package, and reinstalled it (among others that use org)

Hi @andreyorst ,

Good point! ;)

[andreyorst]

I think this can be closed? There's pretty much nothing that can be done on the ox-hugo side.

Recompilation is the only option, and that's basically what has to be done with all other org-dependent projects

[antoniocorbi]

Hi @andreyorst ,

Recompilation works also for me.
Maybe inform users (README?) about the problem and the solution?

[winsphinx]

After I remove ox-hugo and compile, it works in current round.
When I quit emacs then re-enter, it doesn't work again. If I repeat the above step, it works again.
Should I recompile it on every bootup?

Removing only one time elpa/ox-hugo-xxxxx works for me, I've no need to remove it again after quiting emacs. Maybe try removing (if exists) a copy of ox-hugo-xxxxx in the eln-cache dir?

Another option would be to package-delete/package-install ox-hugo and check.

Thanks a lot for your reply.

I checked I have only ox-hugo-20240305.1923 package, and disabled Native Compilation，so no eln-cache.
Also, my org version is 9.7.11 and emacs verion is 29.4 .
