@sam and all interested in typing math in Discourse. I’ve updated the discourse-math plugin so that it uses MathJax V3, rather than the much slower and very outdated V2. As expected, the result is a much snappier user experience, while still maintaining the feature rich environment as compared to Ka…

Pull request to upgrade MathJax to V3 made with all tests passed!

Regarding: https://github.com/discourse/discourse/pull/36212/files This is fantastic :hugs: , but I wonder if we can use this an an opportunity to trim down our repo a bit. Now that we moved mathjax to core, we can lean on pnpm to pull the package and avoid bundling all the source like we do for…

I’ve modified the discourse-math plugin so that it can parse a lot more mathematical input. @sam When I first contributed to this plugin in 2017, I recall that you were quite firm that you wanted very strict parsing. Let me say up front that my main motivation to relax and extend the parsing was so…

@mcmcclur Thank you for your work. It would be great to see these features in the core.

Thanks so much Mark. My big blocker here is that I really want to move to the new patterns for dependency distribution, see: JS Dependency Distribution: MathJax Migration Guide sam: looking at discourse/discourse explain the new patterns for js dependency distribution, investigate how mat…

@mcmcclur I was fiddling with this today: https://github.com/discourse/discourse/pull/36814 Far from ready … but stuff sort of boots with 4.1 which is nice.

[image] sam: Far from ready … but stuff sort of boots with 4.1 which is nice. Yes, this is definitely progress! The first key issue to address, as I suspect you know, is that the fonts are not found. In fact, I fiddled with this line in discourse-math-mathjax.js: fontURL: getURLWithCDN("/as…
