When I try to run the following code (from the REPL) in Clojure:
(dotimes [i 5]
(.start
(Thread.
(fn []
(Thread/sleep (rand 1000))
(println (format "Finished %d on %s" i (Thread/currentThread)))))))
I get the following error:
java.lang.Exception: Unable to resolve symbol: i in this context
clojure.lang.Compiler$CompilerException: NO_SOURCE_FILE:6: Unable to resolve symbol: i in this context
at clojure.lang.Compiler.analyze(Compiler.java:3713)
What am I doing wrong here?
Your code works for me using the latest SVN (1144).
user> (dotimes [i 5] (.start (Thread. (fn [] (Thread/sleep (rand 1000)) (println (format "Finished %d on %s" i (Thread/currentThread)))))))
Finished 0 on Thread[Thread-16,5,main]
Finished 4 on Thread[Thread-20,5,main]
Finished 3 on Thread[Thread-19,5,main]
Finished 1 on Thread[Thread-17,5,main]
Finished 2 on Thread[Thread-18,5,main]
Are you using the September 16 release? You almost have to use the SVN version of Clojure. It's changing way too fast.
