From #69, with some fixes.

Render KaTeX by putting in codeblock of its own language definition, instead of interfering with html sanitizing.

Uses \( \), \[ \] along with $ $$ notation since GPT4 tend to use \( \) and \[ \] notation if not specified.

Also I thought that it better not render if math is in codeblock.

fix node thing
added mhchem and fixed regex

Inline math was a problem, since putting it in codeblock splits it into paragraph. So I used codespan which doesnt has language notation and just added prefix after backtick. better solution?

this looks like something that is brittle and can break lots of other cases. Is there not a better way to detect latex?

I thought so, but looking at KaTeX's own AutoRender, they do does delimeter detecting simmilarly.. so I thought using simple regex is fine.

I agree with that it might break easily and there should be more solid way, but as far as I see, almost every LaTeX detector uses simmilar regex.

I disabled rendering at default and added button to render afterwards if needed.

Hey @morgan9e I was thinking of trying to merge this into my copy. Any warning against? I'd also be happy just to find a web app that renders pasted typical ChatGPT markdown + latex. Overleaf is okish.

It kinda breaks sometimes, like when ( is used else than math notation or notations KaTeX doesnt support.. But thats why I added button to manually render.

Also I think we should remove "$", since like $1000 to $2000 is interpreted as math too.

Closing since it breaks a lot and may require whole new solution.

Maybe we need to patch SvelteMarkdown or something. I'll figure it out.
