Hi Phil:
I guess it's swank night tonight!
The newer versions of slime.el changed the name of the frame-source-
location-for-emacs slimefn to frame-source-location, which breaks
stack trace source file viewing.
This patch fixes that and adds support for finding java files in
addition to the clo

Hi all!
I've been playing around with Clojure in the last couple of days. Very

Yes, this doesn't work because the future fn is executed in a new
thread, that does not inherit the dynamic context in which the future
was created.
Thanks a lot to everbody for the great responses! They certainly helped
a lot!

Problem: Passing primitives from an inner loop to an outer loop efficiently.
Here is what I've found.
The fastest method of result batching, amazingly, is to pass out a list and:
(let [foo (loop ... )
x (double (first foo))
r1 (rest foo)
y (double (first r1))
r2 (rest r1)
z (double (first r2))] .
Hello Clojurians---
I'm about to begin writing a Clojure wrapper for a Java data structure
that's amenable to seq-ability.
1) I'd like to implement the ISeq interface. Could someone point me to some
up-to-date documentation on what I need to implement? Sorry if this is
covered somewhere obvious..

Thanks Rich, I'll take a look.
By the way, Clojure is a beautiful and enriching thing. Keep up the great

Perfect, thanks Stuart! That works great :)
I put it in a convenience macro:

It seems to me you want:
user=> (list + 1 2)
(# 1 2)
As opposed to:
user=> '(+ 1 2)
(+ 1 2)
Regarding examining a function, contrib has some helpers written by
Chris
user=> (use 'clojure.contrib.repl-utils)
(source func)
(show func)
In your case source wont be useful as the function is generated
I've been noodling on the problem of dependency management for a while

I also wrote something to do symbolic regression. I used plain
functions to manipulate quoted trees, and one macro to wrap the
expression in a fn and eval.

interesting idea! It reminds me a bit of the Grape system in groovy.
Groovy uses Ivy for this.
and you can grab the needed library either via annotation like
@Grab(group='com.jidesoft', module='jide-oss', version='[2.2.1,2.3.0)')
or method call like
Grape.grab(group:'org.jidesoft', module:'jid
Phil, it might be worthwhile to look at Ivy (http://ant.apache.org/
ivy). It has real good interop with ant and can easily pull from a
maven repo and read pom files.
