Hi guys,
I've just updated to the latest (1289) version of clojure, and swank-
clojure (slime) doesn't work anymore

If you use AOT compilation, you'll see that this code will add 2 new classes

The latest Clojure version broke many of my code by introducing the
function sequence whose name collided with my sequence monad. So I
decided that since now is the time for breaking changes, I should
solve that kind of problem thoroughly. I just renamed all monads in
clojure.contrib.monad

Vectors are designed for contiguous/sequential data. The case below requires
"removing" elements at arbitrary (keyed) locations in a collection.
Idiomatically, a map is better suited to the job. With a vector you'll be left
reassembling your key.
It's worth noting that calling assoc on a vecto

You sure did. The conversion to lazy-seq code
Practical Common Lisp is also online and free. Though there are significant
differences between the two languages many of the strange and beautiful
concepts that Clojure embraces are covered there. Especially dynamic

How should I say it... It just didn't look "symmetrical" to me.
So, basically, there is a difference between functions returning
sequences - depending on if they are lazy or eager. Hmm...
user=> (reverse [])
nil
user=> (if (reverse []) true false)
false
user=> (if (seq (reverse [])) true false)
If I've been following things correct:
rest _used_ to force the seq, it does no longer.
next forces the seq
In my own mind i'm thinking next to mean (return the seq with the next value
computed), rest now means just give me the uncomputed remaining values of
the seq.

I see nothing in his code or documentation for handling negation or

see any fixed-point or other recursion handling. I *suspect* this does not

I am currently in a masters level Compiler class. We have a final
project for the class and I was wondering if there would be any
defects/enhancements that I could do in Clojure. I have about 5 years
of professional Java experience with dabbling with some other

hello,
what is the idiomatic way to do the following in clojure?

arr = [3 9 4 5]
arr[1] = 7

Yes. I've been thinking about a database layer that would support indexing,
constraints, and so on. One step at a time.
(logic-rule (:fred :x ?x :y ?y) - (:sally :x ?x :z ?z) ("becky" :y ?y)
(not! :janet :qqq ?z) (if < ?x ?y))
Translated into positional notatio
Did you cover logic programming? Any bottom up logic query techniques?
(My motives are probably transparent.)

I'm working on a screencast for PeepCode (http://peepcode.com) that is
aimed at teaching Clojure to users of other dynamic languages.
It's not ready yet, but it should be on sale in a week

Maybe I wasn't clear, I'm talking about the foundational layer.
Instead of:
(def data {
:table-1 #{ { :x 34 :y 33 } { :
Easy enough to do. The only drawback is I'd probably want to force it into
a hash during the query. For large datasets (say 100,000 records) this
might get expensive.

I've got something that's pretty close. There are some other things
in the queue before I can get it cleaned up and ready for public
consumption, but I'm working towards that.

Konrad,
Here's an updated state-m monad transformer. I dropped my CA in the
mail today. I figure if I post a snippet of code to the list, it's
public domain, so do with it as you wish. Or wait till Rich gets my
CA.

At this point test-clojure doesn't generate any new failures or errors
(except the old 'mod' function failures). Coverage is still relatively
small, but (cycle []) bug and case of (reverse []) were caught with
its help when rewriting tests :-)
Thanks for all the fixes!

Makes sense. That would work. It certainly looks cleaner.

I like that. It makes it clear what is a monad, and what is not.

I can't really claim to be handy with elisp, but I got by.
(Is there a guide to elisp functions anywhere? The Lisp
reference didn't include the Common Lisp emulation library,
and I never did find an equivalent to the clojure filter()).
Anyway, here's what I added to my .emacs:

This is great Kresimir. I've wanted to do this for a while, but gave

Expanding your ant task so that others can use it without deciphering

"like any other .NET application" means "needs the .NET runtime.", but
does not need Visual Studio or inserting Tab A into Slot B to get it
all to work.
