Rust LaTeX engine
I'm working on a new independent LaTeX engine written in Rust and no C dependencies at all. You can see it working at https://telox.dev/app/scratchpad/ There's currently not a way to invert LaTeX engine output for bidirectional editing. So you can't easily drag objects around or interact with the page on LaTeX. That's what I'm setting out to change in the name of mathematical exposition. I have more details on my plans here https://news.ycombinator.com/item?id=49689856 I've experimented with a few ways of making the editing realtime and I'm getting in the 10 millisecond ballpark on some edits, but I want to work backwards from the light speed path to see what it takes (besides a lot of time).
