I do not know if this is the right place to ask about this but I would love have something like mdbook for typst. I would like to create preprocessors (e.g., collapsible sections, etc.) and have all the features of mdbook (e.g., summary) while simply writing Typst.
This is something I was looking for, too. Writing Typst is nicer and richer than writing Markdown. I would love for this to exist.
(Sadly, I didn’t find anything. So currently, I’m going with using regular mdbook output, writing custom preprocessors for it, and then using mdbook-typst-pdf to get PDFs from it using a Typst template.)
