raco frog -b just hangs.

Tried to narrow down the source of the error, to no avail.

FWIW, this is the only post in a broader conversion of Blogger posts to Markdown that had a problem.

It's possible that the Markdown conversion was incorrect, but the fact that it renders within Github suggests that the Markdown is OK.

Thanks for the report. This is likely to be the markdown parser. Although I can't try it hands-on until later, my first guess would be to look at the > characters in the quoted blocks -- is the parser getting confused about those? If so, you could try escaping them, \>, as a work-around for now.

Close — it seems to be the left bracket that's fouling it up. Changing < to \< seems to fix it.

This file also kills frog. I'm not sure why.
If I delete everything after line 332 then frog handles it in 1-3 minutes.

On line 233 the <download.racket-lang.org> text looks like an opening HTML tag.

If you change tht to (say) <https://download.racket-lang.org/> it will parse "instantly".

Markdown automatic links require a prefix scheme (protocol) like http:, https:, or mailto:.

Various markdown parsers handle <download.racket-lang.org> in various ways, but none treat it like a link.

Unfortunately an unmatched open HTML tag is an Achilles heal of the markdown parser used by frog.
