pandoc-latex-admonition VS djot

For extending markdown capabilities, there are many plugins/filters. Example [1].

I remember using extensions/filters for citations, etc.

Ultimately it is just some custom tooling around pandoc; so whatever you can do in pandoc, you can get done in the book.

Weird that he did not reference the djot package[0] which seems like his attempt at implementing this thesis.

Since you mentioned you were considering moving to CommonMark, have you had time to look into Djot (also by jpm)? Djot is meant to be easier to parse, and I'm planning to write a tree-sitter grammar for it.

Another recent development here is https://djot.net/ (by the pandoc author). It indeed thoroughly solves both:

Unfortunately for us, he is using Vim, so syntax highlighting for it only exists in Vim for now. (And of course, there's a lot more missing for a major mode than just syntax highlighting to be comparable to org-mode in usability. But pipes in tables, I have wished to have those.)

If you like AsciiDoctor, another option to take a look at is https://djot.net/.

On Scryer Prolog, after evaluating Markdown, we end up using Djot[0] as it is more predictable and standard than Markdown, while being also very readable.

I endorse https://djot.net/. It’s new, not even finished, but it is much much better than markdown/reStructuredText/AsciiDoc[tor]. It doesn’t have a Rust parser yet, but it has a lua parser, and that should be straightforward to use from Rust as just a C library. Also, as this is just for fun, consider actually writing a Rust parser for djot. I started one last year, but got distracted (https://github.com/matklad/djot-rs). And then there is https://git.sr.ht/~kmaasrud/djot.rs, not sure how far along is it.
