Hi,
user=> (defrecord Bar [x])
user.Bar
user=> (into (Bar. nil) {:x 1 :y 2})
#:user.Bar{:x 1, :y 2}
One still has to know, that Bar takes an argument, but one could provide
and API function which takes care of that.
user=> (defrecord Bar [x])
user.Bar
user=> (defn empty-bar [] (Bar. nil))
#'user
Great. Thanks James.

clojure.contrib.string is part of Clojure-Contrib 1.2, whilst you're
using 1.1.
I believe clojure.contrib.str-utils is the equivalent 1.1 library.
(also, clojure.contrib.string was designed to be "require"d, rather
than "use"d).

Hi folks,
I've been experimenting with the new type system in Clojure 1.2, but
I've hit something of a problem. If I define a record:
user=> (defrecord Foo [])
user.Foo
Then I can coerce a map into a type Foo like so:
user=> (def m {:x 1, :y 2})
#'/user/m
user=> (Foo. {} m)
#:user.Foo{:x 1, :y
Okay, this is probably a stupid question, but I have these three lines
at the top of my file:
(use 'clojure.contrib.duck-streams)
(use 'clojure.contrib.classpath)
(use 'clojure.contrib.string)
I get the error message:

Hi all,
I've written an API in Clojure to be consumed by people working in the
Java world. Now most of these people haven't even heard of Clojure;
but all they care about is 1) a working API and 2) with nice
documentation.
1) Something about the API - I tried out various things, types,
records,
There doesn't appear to be an implementation for InternalReduce to
handle an array of shorts.
It also looks like ArraySeq_short is missing from ArraySeq.java
Since there's one for the other java primitives I'm guessing this is
an oversight

Android 2.2 will have a JIT added to the VM which is reportedly
improving performance anywhere between 2x to 5x. Lets hope Clojure

Hi all,
Is any one aware of a Clojure web framework that has built in support
for Comet or BOSH?
Thanks,

I was in to process of writing a rant against condp when I realized I had
been thinking about it all wrong. Here is what I wanted at first:
(defmacro casep [pred & clauses]
`(condp #(%2 %1) ~pred ~...@clauses))
In other words, I want to be able to specify a unary predicate instead of a
binary

Yes. I second that. I hardly ever needed (or saw in other code) more

Thanks a lot for all these fruitful answers! I am very grateful.
Especially the examples of Laurent and Islon where very impressive.
