[PATCH] gnu: Add js-mathjax-3.

Hi all,

attached is my stab at building MathJax@3 from source. The main problem

doing so is that we cannot build any of its build-time dependencies (TypeScript

compile, webpack, babel, …) and some of its runtime-dependencies

(speech-rule-engine) from source right now. Fortunately esbuild can

interpret TypeScript and transpile it to ES6-compatible JavaScript usable

by modern browsers, so we don’t need any of the build-time

dependencies. Removing speech-rule-engine disables all accessibility

features, but that’s a price we have to pay ?

Rendering standard formulas seems to work flawlessly in CHTML mode. But

module loading (for example for chemical formulas inside \ce{}) seems

to be broken. Although the modules are built and loaded by the browser

MathJax does not render the LaTeX environment correctly. I’m guessing

this affects all modules that are not built-in, so I suggest using *-full

builds for now, which have all modules built-in and consequently don’t

have this problem.

I hope the code has enough documentation for others to understand what

I’m doing and why.

Cheers,

Lars
