Nope. It won’t print or pprint at all, with other options or with this option toggled off. (print “anything”) just returns nil without printing to the repl (nor to the Calva says pane for that matter).

Perhaps it has to do with shadow cljs and node repl??

command 'calva.jackin' not found - I'm getting this message when trying to jack-in. Any ideas how to recover?

Strange. Try opening some Clojure file in the project and see if the commands get registered then.
