Just a quick announcement that I've pushed an initial version of
Seesaw, my Clojure + Swing experiment, to Clojars. If anyone gives it
a try, I'd love to hear feedback. On GitHub here:

I really like the code in Stuart Sierra's lazytest:

The code in Enlive is also a really great read:

Having no clue what to make of 0.0.1 precisely w.r.t. its previous
versions numbers, I gathered it's because you can't make out anybody's
modules anyway, in which I agree.

Hi Max,
I have started investigating this, and it works very nice.
I am a noob in Clojure/Java and I have a question about posting to FB using
your library. I tried something like this:

Well, that's sort of wanting to eat the cake and have it.
It's impossible to resolve a symbol where it isn't known where it came from,
if any resolving is to take place, it must assume to be in the current
namespace.
So yes, you're right; syntax-quote would work best here.

better if you are dealing with various records.

Since macros are expanded, qualified vs unqualified issue will be

I recommend reading a book about lisp.
I liked land of lisp:
http://landoflisp.com/
Practical common lisp should be good as well:

Some more:

When you have an understanding of lisp, you can move on to clojure.

Hi all,
I'm trying to calculate the moving average of a certain window size.
One straight forward approach is:
(defn lazy-avg [coll]
(let [[sum cnt] (reduce
(fn [[v c] val] [(+ val v) (inc c)])
[0 0]
coll)]
(if (zero? cnt) 0 (/ sum cnt)
I'm trying to implement a function similar to new, but where
the type is not known at compile time -- so I want to evaluate
the first argument.
With the help of Google, I found the approach used in new*
below:
(ns dynamic-new)
