Easiest way to convert asciidoc to qmd?

[cod3licious]

Description

I have an existing asciidoc book and would like to switch over to quarto, including converting all the .adoc files into .qmd files, since I prefer the qmd syntax. Is there an easy way to (at least approximately) convert from one format into the other?

Use Pandoc to go from Asciidoc to markdown then manual editing for Quarto specific features.

You can use the embedded version of Pandoc via quarto pandoc ....

Unfortunately, for some weird reason pandoc only likes asciidoc as an output format, not input format, so I get the error Unknown input format asciidoc 😔

Oh, indeed I did not see the arrow was only in one direction.
That's unfortunate.

Well, far from perfect, but this command seems to be a good start:

asciidoctor -b docbook -a leveloffset=+1 -o - README.adoc | \
pandoc --wrap=preserve -t markdown_strict -f docbook - > README.md
