I'm afraid that the visual differ isn't helpfully set up for this. Its approach is to fetch the parsoid HTML for the revisions to compare, and then generate the comparison output client-side. It's not terribly reusable outside of the VisualEditor context -- all of the describing of changes that it does leans heavily on interrogating VisualEditor's data model for information about the things that changed.
The best I can say about this for your purposes is that using the parsoid HTML *would* relieve you of having to parse wikitext to work out whether the contents of a math tag were what changed. 🤷🏻 If you do want to dig into this further, check out: https://doc.wikimedia.org/VisualEditor/master/js/source/ve.init.mw.DiffLoader.html ~David On Mon, Jul 5, 2021 at 11:48 AM Physikerwelt <w...@physikerwelt.de> wrote: > Hi all, > > thank you for your feedback. > > @Roy this is a good point, I honestly did not think about it before. > However, in the back of my mind, I remembered this problem had been > solved before.
