So, (map (partial reparse-string is-table) (nth (parse-file "") 6)) fails, complaining about a lack of either #"\r\n" or #"[\r\n]". Essentially, it seems to think a :br should start the text line in that section.

@seylerius where is the grammar you're using to parse? apologies if you posted earlier and I missed it.

and sample file?

Ach, forgot to link to the repo. https://github.com/seylerius/organum
