The conversion is not an issue, there are already multiple tools for that, including a browser plugin with auto refresh.
However the tight integration with the editor, in this case neovim, is missing. At the bare minimum it should show the changed area curently being edited, ideally scroll with the editor scrolling like with common markdown extensions. Currently it just shows a static site that refreshs.
I had a similar idea, however i haven’t seen a markdown plugin, that is well maintained and at the same time simple enough, so that the core, in this case markdown, can easily be replaced with a completely different engine, asciidoctor.
Any recommendations for that?
I also thought about changing neorg, but the missing support for treesitter is a k.o. for asciidoc.
