problem

When I run (cider-macroexpand-1) / "C-c RET" in Emacs with cider on a form I get this error message:

cider-ensure-op-supported: ‘cider-macroexpand-1’ requires the nREPL op "macroexpand" (provided by 

Is this a known limitation? It works for me in vanilla clojure + cider, but not with bb.

repro

From within Emacs, jack into a bb cider session. Invoke "C-c RET" at the end of this expression:

(-> (str "hi ") (str "there"))

expected behavior

Cider should show me the expanded macro.

The babashka nREPL server doesn't implement all CIDER ops. CIDER is effectively nREPL middleware and not part of nREPL proper.
I suggest just using (macroexpand-1 ...) in a REPL instead.
If you want to work with JVM tooling, a handy way to get from a bb project to a JVM project is:

$ bb print-deps > deps.edn

and then just cider-jack-in to your JVM project.

Perfect thx!
