are you aot compiling? If yes delete all the calss files and
re-compile...also there is no reason to require it unless you alias it
to something... a common one would be (:require [clojure.java.io :as
io])...personally, for clojure.java.io, I just use the fully qualified
name most of the times
aaa sorry I can see from a previous post that you already tried that!
this is strange!

You can easily pass seqs to :import...this works fine for me (importing
3 classes from the same package):

The reason it starts with def (and ends in -fn) is because it is a
function used by a macro, which has a global effect.
well, if you mean that the macro (which you've not shown) is the one
that creates the top-level form, then macro's name should be the one
start
well not quite!
you need (-> form
var
meta
:test)
or the same thing written differently (:test (meta (var form)))
Hope that helps,

ps: basically the meta-data sit with the var not the function

If I've understood correctly all you need is (meta form)...

Hi All,
I've a application with following structure. Now I would like to
access meta data of f1 and f2 within process function.
(defn ^{:test true} f1 []
(println "call f1 fn"))
(defn ^{:tes
a pre-condition attached to your fn would be a nice and clean way to
check for upper/lower case without 'polluting' the fn itself with if
statements...just a thought ... :-)

A couple of issues:
1) 'name' is a fn in core so it's almost never a good idea to shadow it
like this...
2) also it is not a good idea for a fn to start with 'def' unless it
actually defines a top-level form inside it like in macros
3)If you need all your keys in capital I think it would be fas

Hi Everybody,
class name clashes on importing same named classes from different

Known as "constant folding", yes.

Have you tried running jconsole to monitor the memory usage? It
sounds like maybe you're running out of heap space and you're mainly
