Hello,
Would it make sense to use instead promise/deliver, and enque computations
in order in agents queues ? (worse parallelism, but more control over the
number of threads ?)

I hate to see agents used this way. If people want a thread pool they
should either use the ones provided by clojure, or create their own.
Using agents when you want a thread pool smacks of ignorance.

That's right, the agents part of my answer is more a hack.
But the more interesting point I wanted to bring to
what you were suggesting, if I understand correctly, is
re-implementing futures using agents instead of a thread pool.
send an action off to an agent to be run, return a promise, the action
delivers to the promise when the action completes. derefing the
promise blocks until the action is run to
Hi,
now that I've stepped back a little bit and acknowledged my ignorance (while
working on it : currently reading Java concurrency in practice :-) ), I
can see why I've been so prompt to suggest that (while I can remember having
said to others that using agents without caring about their state
There should be an initiative to built own ide, look at Java history,

refactoring appeared. Clojure should have such ide, my vote right now
is for clooj, since this is the only one ide written in supported
language itself. Just
Imho, using agents(or fixed size thread pool) in my case could be
worst than using an unbounded thread pool. There's a risk to have all
agents blocked waiting for each other.
The library die-geister seems to perfectly fit my needs. Great!
Still I would be grateful to hear a solution using only the
Hi Curran,
I made this video for hacking Overtone with Emacs:

However, Overtone can just be viewed as an example project - it's really just a
description of how to get a working Clojure/Emacs setup.

Once again, I make a globally referenced, infinitely long stream. But
now I use lazy-seq
instead of cycle:
user= (def ev-stream (lazy-seq (cons true (cons false ev-

user= (defn ev? [n] (nth ev-stream n))
#'user/ev?

foo_fn.class
Has anybody else encountered this with function names containing -.
Is this a bug?
As an avid Emacs user - don't bother. If you just want a no hassle
environment that supports Clojure development use Clooj. Steps -

Yes, I had better success with cake (when I used it). But with the
