Aha! Interesting to hear you were going in the same direction. There are indeed quite some tricky situations to handle since Org (and Markdown) are complex in many ways.

the approach I am taking is to combine the PEG with a step of AST processing in order to then produce a correct and descriptive tree structure (for later rendering).

I do agree the Guile library has some spots to improve but honestly, I am already enjoying it so much, and it's far better for the Lisper in me than other things I've tried. I also find S-expressions much more comprehensible and self-documenting.

Looking forward to seeing what you do with it :)

I am indeed hoping that this library is useful for more people and that perhaps things like Haunt blog generator can use it (and other interesting uses)

As for nested markup, and nested lists it has been tricky, but so far I've really promising results:

(assert-equal #:got (inline-org->html (inline-org->ast "*bold with /italic/*")) #:expect "<strong>bold with <em>italic</em></strong>")
