Hi,
Some assemblies are loaded by default an can be used directly. But
like IronPython, you will need to *explicitly* load most assemblies to
be imported into your program. This differs from C# which does it
"under the hood". The Assemblies can be loaded from the GAC or from a
dll if it is not loa
Guys,
I seem to have thrown myself in at the deep end here !
I'm writing some clojure which interacts very heavily with some pojos,
making, hopefully, millions of method invocations a second.
I tried :

user=> (set! *warn-on-reflection* true)
true
user=> (defn fn1 [s]

Meikel,
Thanks for the quick answer.
So I was only one step away from a solution !
I had :

'.length arg)] (eval (list 'fn arglist body)))
Reflection warning, NO_SOURCE_PATH:52 - reference to field length
can't be resolved.

can't be resolved.

I get

which is what I was hoping for. Or maybe you cannot do this at runtime?

Right now I have better ways to use my time than hacking on a compiler that

Hi all
I made a naïve attempt to implement the minimax algorithm in Clojure.
I would appreciate any comment on style, wrong (or right) use of
idioms etc.
Specifically, can I create a “contract” for the function I use, like
heuristic, to formalize minimax requirement from it?
Thanks

Thank you!
I have not yet picked a license for the library, I am open to any of
them, but would like to know what the preferred license is for the
project. My first leaning is towards a permissive license such as
BSD. What is preferred or recommended for clojure and its libraries?
Thank you,
K
IANAL.
The standard seems to be EPL 1.0, because it's what Rich uses for
Clojure & Contrib. My understanding is that this causes problems w/
the GPL, so you'll probably want to stay away from that.

You can use a map as a key in another map. The clojure.set namespace
has a function index that does this:
user=> (doc index)
-
clojure.set/index
([xrel ks])
Returns a map of the distinct values of ks in the xrel mapped to a
set of the maps in xrel with the corresponding
Hi Adam,
You need to use the gen-delegate macro to create delegates,
See http://wiki.github.com/richhickey/clojure-clr/clr-interop
The signature of the macro is (gen-delegate Type [args] body) whereby
in case of event-handlers you would typically use the EventHandler
class.
The code becomes then

When it comes to distinguishing certain types of symbols from other
things, should one use prefixes or suffixes?
Example: naming tests with clojure.test/deftest. If you distinguish
your tests’ symbols at all, do you do “t-addition” or “addition-t”?

Hi all,
I am trying to use (abuse? *) zip-filter to remove some nodes and
return the xml tree to me.
If I do something like this:
(xml1-> zipped-xml zf/descendants :model zip/remove zip/root)
I can remove one :model node, but what if I want to remove more than
one or all of the :model nodes?
Ouch. Burned by documented behavior :). Thanks for pointing that
out.
Seriously, though, I'm not the last that will get confused by this.
My suggestion would be to make (case) copy the value from the *var* at
compile time and use that. In fact, I decided to do just that and
created (case-eval).
