That's right, the "agents" part of my answer is more a hack.
But the more interesting point I wanted to bring to the table for
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 co

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 th
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.

Yes, I had better success with cake (when I used it). But with the
lein setup, I believe most of it goes into a swank buffer of some
sort, which also contain a lot of other (non-related) output, and
exactly where in that buffer it also ends up seems a bit
undeterministic. But again, just my experie

Now that Leiningen has user-level plugins, there's no need to put

I think it's consistent.
Have you looked at the *swank* buffer? Maybe your's is looking
differently than mine, but there's lots of stuff that I did not but
there, and which I would not have there.
My issues with this is related to running servers and catching debug
output from it while it is running (yeah, I really should

Everything in there is output from lein jack-in. Much of it is elisp,

Hi Curran,
I'm in the process of learning Clojure and emacs as well and have run

problem. I grabbed the 23.3 version of emacs from their ftp site and
did NOT use the emacs starter kit. I discovered that the version of

I believe the bug can be blamed on "nth".
Using "nth", I make a function which should be identity on natural
numbers:
Clojure 1.2.1
user=> (defn ident [n] (nth (iterate inc 0) n))
#'user/ident
And it works, for reasonable size numbers:
user=> (ident 12345)
12345
user=> (ident 7654321)
7654321

G'day.
The API documentation for clojure doesn't specify if the sort method
is stable, unstable, or "implementation defined".
Java defines sort to be stable, but Clojure also has two other
targets, and I can't tell if I am safe making the assumption that the
stable behaviour will carry over to th

My recollection of how cake did it was probably wrong.
As for how I would like to have it, I would like to have all output
from all threads appear in the emacs repl buffer, similar to how it

to do or found any workaround for, ex
