What's the code-block plugin this forum is running?
I notice this forum is displaying markdown code-blocks more nicely than vanilla-Vanilla
i.e. these code-blocks thanks
Not only is that almost certainly my best starting point, I'd also want to make sure my plugin plays nicely with the existing one.
Incidently, I'm pretty sure that, without any plugin, markdown code-blocks are incorrectly rendering less-than as < instead of < but given @linc 's comment that "My biggest bug concern is our Markdown support. It's kinda gross right now" I somehow doubt this needs reporting.
