How to define math macros in the myst.yml file?

[tdsimao]

I have a jupyter book with a set of macros. Now, I am using jupyterlab-myst to edit it on jupyter lab.
Most things work out of the box; I just need to define the macros in the format myst expects. I manage to do so by adding the macros in the front matter of a file.

However, I would like to use the same macros across the whole book. In that case, the documentation of myst, mentions that we can add the macros to the myst.yml file. Unfortunately, I was unable to make that work while using the jupyterlab-myst plugin on jupyter lab. Any ideas what could be the issue? Does anyone have an example?

The jupyterlab-myst extension currently doesn't read from the myst.yml, and is a known limitation. You can add them at the top of the document as you have found for now. If you are using mystmd locally (e.g. myst start etc.) then that will work to share the macros.

Both of these tools are part of the jupyter-book organization (part of project jupyter), and there is a discussion board over there as well!
