Cannot load LaTeX packages into preamble.sty

[DylanJVA]

I'm trying to use the physics package and i tried including this in the preamble.sty: \usepackage{physics} and I also tried this: \require{physics}, which was according to this obsidian forum post. The example you give does not show how to include some LaTeX package, it only shows how to define a macro. Unless thats not what this extensions can do, can you please explain how to use this extension to use an arbitrary LaTeX package?

You cannot, Obsidian uses MathJax which while similar to latex is not latex.

Hi @xldenis it appears your answer contradicts with what you mentioned in https://forum.obsidian.md/t/new-plugin-mathjax-extended-preamble/10174 about using \require{physics}.

Wondering if I missed anything? Thanks 😊

Update: Oddly enough, with preamble.sty like this

% Enable MathJax's "physics" package, which partially implements the LaTeX
% package "physics".
\require{physics}

I am indeed able to use the physics package in Obsidian, e.g. the differentials and partial derivatives render perfectly for me:

\dd x, \dd[2]x, \pdv[2]{f}{x}, \pdv{}{x}{y}

Sflr, please see https://docs.mathjax.org/en/latest/input/tex/extensions/physics.html - you can load the physics package dynamically under MathJax but it might not correspond entirely to the LaTeX physics package (not sure what the exact differences are). Nevertheless I think it should work for most usecases.

Can confirm this works. Thank you! Not sure if it was added in the update...
