hmm

How can I print the stacktrace in repl?

user> (try
        (throw (Exception. "dupa"))
        (catch Exception e (println "this works")
               (.printStackTrace e)))
this works
;; => nil

looks like stderr is redirected somewhere else

hmm

I can reproduce your behaviour, but I notice there’s actually not stderr from this method call

you can check your nrepl-messages buffer

clojure.stacktrace/print-stack-trace works just fine, though

@malabarba: this might be some bug in the stderr redirection middleware

confirmed clojure.stacktrace/print-stack-trace works

still, this is definitely a bug in cider

is there any hack around that? how can i redirect stderr to where stdout is printed?

there’s no hack

maybe disabling it the middleware will fix this, but I’m not sure

has to be tested

if there’s no output coming from nREPL

there’s nothing you can do but find why the output is missing there

I'm not sure if our stdout middleware even tries to do anything about stderr

Probably not

Which would explain why it's left on the server buffer
