Thanks a lot for that David,
It works perfectly for me.
Are there any circumstances where it doesn't work? I haven't run into
any yet, but if there are, I'll design my program around it.

Definitely having the ability to see the full stack trace is be
useful. I wonder though if that should be the default output. Maybe by

Glad to be of help. To be totally honest I hadn't really tested it too much,
so I don't know ;) One obvious limitation here is that it doesn't work with
multiple inheritance (it only looks at the first item in the parents set).
As long you're sticking with a Java-style single inheritance model thi

Here is an example for loading clojure code. I had trouble with this
before. I believe that once the script is loaded, it is loaded per
JVM instance.

Also, any suggestions are welcome.

I'm trying to use Clojure to call a library via JNI. Here's a working
piece of Java code that I'm trying to convert to Clojure:
import libfoo.Foo; // A GlueGen-generated wrapper
class Test {
static {
System.loadLibrary("foo"); // The original library
Fixed. Thanks for the report.
Aside from being a helper function for sqrt, exact-integer-sqrt is
available in some Lisp and Scheme implementations. At first glance,
you might think that calling (floor (sqrt n)) is sufficient, and no
special function is needed. But for large integers which are

Hello,

describe-key (usually C-h k) followed by a key will tell you what a

On my setup C-x C-b is bound to ido-switch-buffer--it is not
immediately obvious how to make it pop the buffer list in the current
window.

Excellent tutorial. I pretty much zipped right through it, even though I'm
on osx and had to figure out the right way to get a git client for myself.
Thanks!

I see, thanks for the clarification. It does seem like you are purposefully
creating a situation in which type will fail since something more likely:
(type (proxy [clojure.lang.IRef][]))
works fine.
I'm wondering if a CLOS-like system would really have to handle such a

Thank you!
And sorry, I made serious typo in last question.
I had to write "private" instead of "public".
(I want to pull my hairs.)
I'm not sure, I think there might be cases the error part not needed.

Hi *,
I just came back from EclipseCON 2009. There was a short talk about
Clojure (that I unfortunaltely missed) but the slides are available
here http://www.eclipsecon.org/2009/sessions?id=630, click though to
gpublication.
Interesting, two questions:
1. What is the state of the Eclipse plug-i
If you don't care about the "leftover" portion that exact-integer-sqrt
returns, you can do something like:
(let [[floor-sqrt _] (exact-integer-sqrt n)] ...)
or (first (exact-integer-sqrt n))
so I didn't want to expose another function which returns only half of
the information that this one does.
I'm one of the ones who /didn't/ come from Java to Clojure. I can only
get myself so far looking at Java examples. I need to make a context
menu that will pop up when I right click inside of a JEditorPane. I'd
appreciate it if anyone could whip me up a simple example of doing
something like that i

Something like this in your ~/.emacs might do the job:

I know I can ignore leftover part, but my concern is that exact-
integer-sqrt will calculate leftover if needed or not.
Why not 2 public functions?
like mzscheme's "integer-sqrt" and "integer-sqrt/remainder"

Looks great, thanks a bunch.
I'm not coming from a Java background so any swing example I can get my
hands on is great.

I noticed an inconsistency with refs and get:
(def ref-map (ref {:a 1, :b 2}))
(ref-map :a)
=> 1
(get ref-map :a)
=> nil
Now I haven't seen any documentation that getting the value of a ref
without a @/deref is supported at all, so maybe this isn't supported.
But if those forms are supported,
I changed "integer-length" to use numberOfLeadingZeros or bitLength methods.
It reduces execution time a bit. So that of "exact-integer-sqrt" too.
;; test with name integer-length-new
(defmulti ;; #^{:private true}
integer-length-new class)
(defmethod integer-length-new java.lang.Integer [n]
