There is some configurability you can try use. Have you seen this page? https://calva.io/pprint/

I’m trying to setup zprint with the above and I get: Option errors in this call: In the key-sequence [:print-depth] the key :print-depth was not recognized as valid!

using zprint 1.0, I couldn’t figure out what Calva expects since I don’t see zprint mentioned in the depedencies of the jack-in

Calva doesn't add dependencies for zprint. Maybe it should...

I just got thrown in that doc page, zprint is recommended but not very clear how to enable…

puget and fipp work fine OTOH

I don't quite remember how I impemented it, but reading that doc page, maybe I was too quick to say that Calva doesn't inject it. I think I tried make it such that if you have zprint configured as your server side pretty printer, then Calva will inject it on the next jack-in. Might be that that doesn't work of course.

Wouldn’t it be nice when nRepl gains sideloading? No need to configure anything, let the tool inject at runtime...

Yeah, I think that is pretty close to becoming real.
