Hi
Is there a way to introspect types defined with deftype and
defrecord? I'd just like to know the field names and their order in
the constructor. Java reflection works fine but requires some
fiddling around to filter the static fields and __meta and __extmap.
It feels like something that someo
I think the problem is that cwicket.HomePage resolves to a class
object (like cwicket.HomePage.class in Java). So (class
cwicket.HomePage) returns the class of the class object which is
java.lang.Class. And that's not a subclass of Wicket's WebPage. Try
this:
(defn -getHomePage [this] cwicket.
partition creates a sequence of sequences of adjacent values
user=> (partition 2 (range 1 7))
((1 2) (3 4) (5 6))
and you can apply reduce to each of the sequences using map
user=> (map #(reduce + %) (partition 2 (range 1 7)))
(3 7 11)
or
user=> (map (partial reduce + ) (partition 2 (range 1 7

I've converted some code that used gen-class to use deftype and defprotocol and
the results are great so far. The code is shorter, easier to write and

I was thinking exactly the same thing. It feels like there should be
a better way than instance? ...Sequable. Unless there's a reason
that's a bad idea.

Hi
Are there any fundamental reasons why the Keyword class shouldn't be
serializable? I've been playing around with Clojure and Wicket and
it's not possible to use maps containing Keywords in Wicket page
classes. Wicket pages are serialized and stored in the session
between requests and this fa

I've noticed that changing namespace with ns and then doing a def
doesn't behave the same inside a do form:
Without the do form it works as expected:
user=> (ns a) (def foo "foo")
nil
a=> #'a/foo
a=>
If the same code is executed inside a do form the var is defined in
the original namespace. I
Hi
I've been playing around using symbols with metadata as struct map
keys after reading this message:
http://groups.google.com/group/clojure/msg/68e7036dbd8ded29
It all works OK except when you use find to extract an entry. find
returns an entry containing the key passed to it, not the key in
13 matches
