How do I use LaTeX physics with Typst?

[alex180500]

Description

Hello! I'm trying to use formulas in quarto with the typst backend that uses the physics package. For example:

$\ket{psi}$

Is there any way to include these with typst?

I believe you are in the wrong place.
You should look in Typst documentation to know if it supports this and how.

[mcanouil]

That would be Pandoc's writer.

You can try using pure Typst to make your equation work if it is supported similarly to jgm/pandoc#9294

Then look for already opened issues (or discussions): https://github.com/jgm/pandoc/issues

But before reporting anything on Pandoc, please do ensure it's supported by Typst in the first place.

edit: I don't think Typst supports this (https://typst.app/docs/reference/math/)

echo '$ ket(psi) $' > demo.typ
quarto typst compile demo.typ

[mcanouil]

I thought math is converted as TeX math, in fact I get this warning:

[WARNING] Could not convert TeX math \ket{\psi}, rendering as TeX:
  \ket{\psi}
      ^
  unexpected control sequence \ket
  expecting "%", "\\label", "\\tag", "\\nonumber", whitespace or "\\allowbreak"

That does not seem to be a Typst error. (maybe that's Pandoc)
Please provide a fully reproducible example.

Yeah typst does not support ket yet but there is the physica package: https://typst.app/universe/package/physica
This has support for all physics functions, but I do not think there is support for typst packages yet in quarto

Support for Typst packages (as LaTeX packages, there is an auto-install though) does not come from Quarto.

Use include-* and partials/templates to add them:

• https://quarto.org/docs/journals/templates.html#typst-partials
