Using external package

[Charles-Christophe Thomart]

Hello,

I am using MathJax to write maths on my website for my students.
I'd like to use a package that can be found here :

https://ctan.org/pkg/profcollege

Unfortunately, I've read that using packages is difficult because MathJax "is not TeX but simulating TeX". And package that have not been translated in javascript can't be used.

I've also found this :

window.MathJax = { loader: {load: ['[tex]/color']}, tex: {packages: {'[+]': ['color']}} };

to load extension. Does extension and package refer to the same thing?

I'd like to try loading the above package, but am a bit lost of where to install the package in order to let Mathjax find it.

Can you please give me some directions?

Thanks

Yes, that is correct. MathJax is not TeX, it is a javascript library that implements a TeX-like syntax, but the underlying code is completely different, and it doesn't implement the low-level macros needed by most LaTeX packages, so it is not a straight-forward process to migrate a TeX package to MathJax. It would have to be converted to javascript by hand.

Yes.

You will not be able to use the LaTeX package. I am not familiar with the package, but looking at the documentation, it seems to be a pretty complex one, so converting to a form that MathJax could use might not be easy. If someone is interested in trying to do it, we could give them some pointers, but it is not something that the MathJax team is able to pursue at this time.
