Quite promising: one thing that would probably accelerate adoption would be to provide at least one language parser that can go to/from the format to a data structure of some kind.
Agreed! This is my biggest need. If you want to contribute, or know of any open source libraries that might help me build a more robust parser, let me know -- I'm only a casual coder, and this project really stretched my capabilities of recursive thought ::o
You could consider parsing into Pandoc AST (just need to output the JSON representation of it). Then you can automatically interface with all the output formats supported by Pandoc, including HTML. See pandoc --from json, and https://pandoc.org/using-the-pandoc-api.html
The parser in its current form is here: https://github.com/gamburg/margin/blob/master/parser/js/Marg...
