Pretty printing in babashka

[frankitox]

Pretty printing in babashka doesn't work, if I try to print something it ends up using pr-str, so in the log buffer you'll see something like:

{:hello "world", :some "other", :stuff "that's", :pretty "printed"}

Thanks to @borkdude I found that babashka's nrepl server uses clojure.pprint/pprint for some values of :nrepl.middleware.print/print.

https://github.com/babashka/babashka.nrepl/blob/c8c8a766e026d5f87e0968a179dad70e13aa13ee/src/babashka/nrepl/impl/server.clj#L25-L28

Once I added "conjure.internal/pprint" to this list, I still got everything printed in one line. Then I realized babashka also has a custom "right-margin" key for :nrepl.middleware.print/options.

For this I ended up modifying conjure like this:

But it may make more sense to add a default value to babashka, Clojure's code base uses 72
