If part of the script to build an RPM package is this command: ant then you should run the command ./antsetup.sh just before that.

Re: Clojure 1.5.0 RC 1
If find this odd, these days you need remote access to install things, wether it's Maven or some RPM repos is irrelevant. Pulling RPMs by hand is a nightmare, even worse than Maven, there is a myriad of RPM dependencies out there depending on your Linux distro. Jochen, I would suggest implementing apache archiva on a server that has internet access. Using lein on this server would allow you to pull the dependencies locally and then transfer them by hand on the other server if needed. You can define repos to search in archiva (you can add clojars, sonatype is there by default I think). If your build server has access to this gateway server, it's even simpler. Archiva can serve as a cache for all the other computers that need artifacts from maven. It would require you to change the repos in your builds to refer to your archiva repos but this should be a minimal change. You can even add your own artifacts if you need to. A typical example are projects that do not publish to maven. Archiva is very simple to use and configure compared to other softwares like nexus. It's comparable to apt-proxy. If you need more help, drop me an email off the mailing list.

Re: Clojure 1.5.0 RC 1
Jochen, Official Clojure libs including test.generative already go through a strict build process using Hudson + test matrixes against multiple JVM implementations. You are creating an RPM from components that are not managed through RPMs but through an alien build process. Do you intend to rerun the Hudson test matrix against multiple JVM implementations ? If not, your current build is far from being complete compared to what Hudson does. Build redundancy here does not provide any added value. Most users source the implementation from Maven or through direct downloads, Hudson must not fail building these artifacts upfront. It already guards against corrupted artifacts. Creating an RPM here should only be a nicer way to package all the dependencies out from Maven and place them at the appropriate spot in a Fedora system. Getting a proper JVM if necessary is part of that process (this is an RPM dependency). As a Linux user I would not expect more from such a package. Luc P.

[ANN] dj.plurality, generic dispatch decomplected
Previously discussed
here
https://groups.google.com/forum/?fromgroups=#!searchin/clojure/plural/clojure/KC-zfUE1rXk/ifURo1ReSugJ
In that thread, Chris Ford talked about opening up the implementation of
the dispatch function of multimethods. I've implemented that idea but I go
further to decomplect the datastructure and resolving algorithm. Also I've
decomplected state (identity), as plural-fns are immutable values. To
reduce the number of protocols generated, I'm using metadata to enable
extensibility (defining additional methods).
Code is found here:
https://github.com/bmillare/dj.plurality
You should notice that the implementation is almost nothing. The core of
plural-fns is in the specification as the only real helper function I
provide is update-implementation.
I've provided a basic multimethod implementation without hiearchies
(perhaps merge work with brandon
bloom?
https://github.com/brandonbloom/dispatch-map/tree/master/src/dispatch_map).
I've also hacked together a naive predicate dispatching system using David
Nolen's core.match.
I'm interested in feedback.
Simple example:
(require '[dj.plurality :as dp])
(let [x (dp/-simple-multi-fn {java.lang.Long inc}
type)
y (dp/update-implementation x
assoc
java.lang.Double
dec)]
[(x 3)
(y 3.0)
(y 1)])
= [4 2.0 2]

Can't get ritz-swank working
I'd like to move away from lein-swank and swank-clojure, since they're noted as deprecated (though still working for me in the context of Clojure 1.4.0 and Emacs 24). I've tried working with nREPL + Emacs, but it just doesn't seem as nice what I get with lein-swank (stacktraces and other aspects of the integration feel more raw). What I'd really like is to get lein-ritz and ritz-swank https://github.com/pallet/ritz/tree/develop/swank working, as they seems to be the proper slime/swank successors to lein-swank and swank-clojure. I've tried a couple of times in the past couple of months to setup lein-ritz / ritz-swank, but they just don't seem to work for me. I've followed the instructions in the README to the letter, and then tried tweaking things here and there to see if I can figure out what's going wrong ... nothing seems to work. Long story short, after I run `slime-connect` in Emacs, I get a warning: Versions differ: 2010-11-13 (slime) vs. 20101113 (swank). After choosing to continue, I'm told a connection has been established, but no REPL appears, and I can't seem to bring one up manually. Any help or suggestions would be appreciated. -- Michael Bradley, Jr. @michaelsbradley -- You received this message because you are subscribed to the Google Groups Clojure group.

No, it was pushed one day before your 1.4.3 changes :-) I think it was just a stopgap for lein-swank not working with clojure 1.5.0-beta1.

Use repeat with a function argument
I'm trying to use repeat with a function argument. This works:
(reduce + (filter (fn [number] (zero? (some #{0} (map mod (take 2 (repeat
9)) [3 5] (range 1 1000)))
This doesn't:
(reduce + (filter (fn [number] (zero? (some #{0} (map mod (take 2 (repeat
number)) [3 5] (range 1 1000)))
Why can I use (repeat 9) and not (repeat number)?

Because you call zero? on nil, which doesn't work. Instead of (zero?
(some #{0} ...)) use (some zero? ...).
Kind regards

Re: Use repeat with a function argument
*repeat* is not supposed to work with functions, but there's *repeatedly.*
