Project format `revealjs` uses old version of MathJax #4493

Open sbrisard opened 1 year ago

sbrisard commented 1 year ago

For a revealjs document format, Mathjax is configured as follows

      math: {
          mathjax: 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js',
...........
          },
        },

while for a book, we get a more recent version of MathJax

<script src="[https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml-full.js](view-source:https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml-full.js)" type="text/javascript"></script>

Is it intentional, or should it be considered a bug? Can I specify the version of MathJax I want to use?

Currently the Pandoc Revealjs format supports only MathJax v2. It used to be that Reveal only supported MathJax v2, but in Reveal v4.2 they added support for MathJax 3 and KaTeX. I believe there needs to be a change in Pandoc to be able to take advantage of this (see this discussion: https://github.com/jgm/pandoc/issues/7660).

@tarleb What's your viewpoint on this?

Just a note to self that it seems specifying Mathjax option load correctly Mathjax 3 https://github.com/quarto-dev/quarto-cli/discussions/3127#discussioncomment-4031511

need to look if this is now ok with the plugin too.
