Parsing AsciiDoc in Prolog

Hah, I forgot to celebrate someone submitting my stuff here for the first time!

I'm a bit embarrassed I've forgotten most of what I wrote about parsing. And much of it is likely wrong or bad advice. But I had some fun making some AsciiDoc parsing work. My intuition still says Prolog might be a very good choice to parse these kinds of languages, but really I have no solid knowledge to back that up.

I fell in love with Prolog about a quarter of a century ago. Although you ultimately realize it's not magic and it's quite limited, it's a trip. It is one of my go-to recommendations for people who want to try something new.

The main limitation with DCG-parsing (and, frankly, with Prolog overall) is that in case of parsing error it won’t tell you the position of the error, it simply tells you “failed to parse” (false).
