I want to have a way to print progress message before and after
invoking a function/expression. Came up with this macro
(defmacro run-with-msg [msg & body]
(doto *out*
(. write (format "%s..." msg))
(. flush))
`(let [res# ~@body]
(println "done")
res#))
user=> (run-with-msg "Working" (Thread/sleep 2000))
Working...done
nil
But msg is not printed by itself. In example above I don't see
"Working...". As you can see I tried to print directly to *out*
(instead of printf) and explicitly flushing *out* with no avail.
Any idea what is going on here?
