Ich hab letzte Woche einen Vortrag vorbereitet und hatte keinen Bock auf Pixel-Geschubse mit PowerPoint & Co.

Hab daraufhin mal https://revealjs.com ausprobiert, das ich an dieser Stelle weiterempfehlen möchte.

Es handelt sich um ein JavaScript-Framework. Die Präsentation erstellt man, indem man eine einfache HTML-Datei editiert. Jede Folie ist eine <section>.

Es gibt auch einen grafischen Online-Editor, der aber kostenpflichtig ist. Wer HTML und etwas CSS kann, braucht das aber nicht.

Und das Ergebnis ist recht ansehnlich. Die automatischen Übergänge machen was her. Es gibt verschiedene Themes. Die Präsentation läuft im Browser über einen lokalen HTTP Server und die Speaker View kann man in einem extra Fenster öffnen.

#RevealJS

Once again I went down a rabbit hole figuring something out, and now you -- yes, you, random person on the internet -- can benefit from my work.

I write slides for my classes in markdown and turn them into reveal.js slides. Sometimes I want to post the slides, but I want to strip out speaker notes and other non-useful bits. I could edit the output, maybe, but...ugh. Let's do this properly.

You can write filters for pandoc, but the documentation just wasn't that great.

Well, I figured it out: https://gist.github.com/dandrake/1b6deb7779b5629f75b35bfac3a2f9aa

I create my teaching materials as #OER with #EmacsReveal [1]. For my course on IT Systems [2] in summer term 2025, I switched to #Kokoro [3] as #TextToSpeech model, and students generally liked the quality (see README of emacs-reveal for evaluation results). Teaching resources are video-like, interactive HTML presentations with audio, generated from #OrgMode text files using GitLab CI/CD pipelines.

This holiday season, I found the time to release #EmacsReveal 9.54.0, which includes the settings I used for IT Systems. I also updated the #TTS Howto [4] to use Kokoro.

Feel free to reuse my course materials and emacs-reveal! All the best for 2026!

I just enhanced/updated my JavaScript for Reveal.js in Quarto to better support native PDF export mode and nested fragments inside tabset.

let els = document.getElementsByTagName("aside"); let suma=0; for (let i = 0; i < els.length; i++) { suma += els[i].childNodes[0].textContent.replaceAll('\t', '').replaceAll('\n', ' ').split(' ').filter(function(e) { return typeof(e) === "string" && e.length > 0}).length}
