Thanks, Jim. But with-out-str only works for output to
*out*(stdout), but not *err*(stderr). A quick test is:
(with-out-str
(try
(throw (Exception. "Hello"))
(catch Exception e
(.printStackTrace e))))
which it returns: "" but the stack trace still gets printed out:
java.lang.Exception: Hello

I don't know if you can suppress it, but you can certainly
ignore it with 'without-str' which will give you what was
supposed to be printed out, as a string...then it's up to you
what to do with it... :)
HTH,

Hi, guys,
I'm currently playing clojure with android monkey runner. So
far it works fine but just one unpleasant thing -- the
android monkey runner default prints a lot of junk
information to stderr such as:
March 05, 2013 4:46:47 pm com.android.chimpchat.ChimpManager
sendMonkeyEventAndGetResponse
These printing operations are evaluated inside its library
when I call a method such as IChimpDevice.touch.
I'm writing some wrappers around the api:
(defn send-touch [^IChimpDevice device x y]
(.touch device x y TouchPressType/DOWN_AND_UP))
Is it possible to suppress the its output to stderr and make
it something like(in pseudo code):
(with-stderr-discard
(.touch device x y TouchPressType/DOWN_AND_UP))
I cannot discard the whole program's stderr output with
commands like
java -jar xxxxxx.jar 2>/dev/null
since I need vital stack trace information from other places
for debug purpose.
Any help would be appreciated.
