This method that makes a simple call to the log4j library throws an
exception even though the message it written to the file. Not sure if
there has something to do with static methods again.

hello,
i'm trying to start learning clojure with lein but i get into
trouble. I'm doing simple project:
lein new foo
cd foo
lein deps
echo '(println hello)' src/foo/core.clj
lein run -m foo.core
hello
Exception in thread main java.lang.NullPointerException

Hi,
lein run looks for a -main function in your source file. This is a
convention
borrowed from java (and other languages).
The null pointer exception is probably lein or clojure looking for -main.
echo '(defn -main [] (println no exception)' src/foo/core.clj
lein run -m foo.core
hello
asdf
To use lein run, you need to do two things:
1) Write a -main function (defn -main [] ... ) in whatever namespace you
like (you could put it in the core namescape, like you did in your echo
statement for the (println foo)). For example:
(defn -main []
(println foo))
2) Specify which

I wasn't aware of the group-by function. Being new to clojure, I spent a lot of
time coming up with my complex function. Seeing the one line solution really
blew me away. Thanks!!

I'd support their addition into core.
Also, regarding Konrad's comment:

Hi,
For the last few weeks, I've been working on a Clojure Swing wrapper
called Seesaw. I've learned a lot about Clojure so far, but I think
it's time to ask for some feedback. If I wait 'til it's perfect or
complete, ... well, then no one would ever hear from me. The code can
be found on github

If they don't end up as part of the new lineup of contrib libraries,
would you at least keep them on github.com?

Thanks for the feedback and righting some things for me. Can you
speak to the -? and -? macros, specifically if you think nil should
be handled differently, or if these macros code find a new home in
