Hello smart people! With all the talk about Emacs 29, I figured we should update Org Mode to use MathJax 3, to catch up with the rest of the world.
>From the documentation (for MathJax 3.0 released in 2019): > Version 3.0 of MathJax is a complete rewrite of MathJax from the > ground up, and its usage and configuration is significantly different > from that of MathJax version 2. In practice, MathJax 3.2 renders mathematics faster and better, plus it significantly improves LaTeX support. For instance, one can typeset calculus with the built-in (!) 'physics' package, like in LaTeX. More information on the recent progress (made in 2019-2021): https://docs.mathjax.org/en/latest/upgrading/whats-new-3.0.html https://docs.mathjax.org/en/latest/upgrading/whats-new-3.1.html https://docs.mathjax.org/en/latest/upgrading/whats-new-3.2.html See the attached [working, but WIP] patch. My question for you: How do we change the 'org-html-mathjax-options'? - 'scale' has now the value in [0, 1] and not in [0, 100] - 'scale' should exist as a number and not string - 'font' did not make it to MathJax 3 [*] - 'linebreaks' did not make it to MathJax 3 [*] - 'autonumber' has the values in lowercase now - 'autonumber' became 'tags' in MathJax terminology [*] coming in MathJax 4, currently in alpha How does Org mode approach these kind of breaking changes?
