Re: Getting .NET Version of Clojure to run

The warnings are given at any point where the compiler is compiling a host expression (CLR interop) and it can't resolve the exact method to call at compile-time. Some of these can't be avoided and are normal. The reflection warnings are because *warn-on-reflection* has been initialized to 'true

I wouldn't call this a memory leak: vectors have a bigger memory overhead than before (additional PersistentVector$Node and AtomicReference). On Sat, Aug 15, 2009 at 2:13 AM, Andy Fingerhut < andy_finger...@alum.wustl.edu> wrote: > When I did this, one of the first several lines of output include

Clojure with maven - how to?

Hi, I've just tried to use clojure-maven-plugin bit do not know how to start. It does not compile anything. I probably have to configure it but haven't found any examples yet. I've also tried maven-pom, which has an example, but am not sure how to make it discover clj files (in the examples, the

How to have a fast access to a java array of non-primitives?

Dear all, I try to write a program where I access a java array of non primitive and realize aget is very slow. (6x slower than the same program with clojure vectors instead of java arrays access) I tried a few combinations of type hints but can't manage to prevent mty program to spend most of

Re: How to have a fast access to a java array of non-primitives?

You need to specify the array type. For example the following produces a primitive array of n javax.vecmath.Vector2d elements. (defn #^"[Ljavax.vecmath.Vector2d;" point-array [n] (make-array javax.vecmath.Vector2d n)) It works. If you want to see it in action take a look at: http://github.com/

Re: How to have a fast access to a java array of non-primitives?

Thank you very much for your answers. The syntax was difficult to guess. Is there a general rule for forming the internal name of types? It seems after a few tests that is is slightly slower (15-20%) than making a final static function: static final A arrayAccess (A [] array, int i) { return arr

Re: "Clojure is FAST"

to me, an exciting thing about clojure (there are many to pick from) is that you'll have a good chance (from what I understand ... I haven't tried it for this purpose myself, yet) of having correct paralellizable code -- that is, code that gets a speed up due to parallization. Speed Up ==> Fast.

Re: "Clojure is FAST"

Well, by claiming that clojure is fast, you are making an invitation for people to try it and see. If they report otherwise and back it up, that should be ok. I'm not sure if that's the case, here, but I, for one, have a concern that if we're only aloud to say nice things in here, then people onl

Re: Parallel garbage collection worthwhile?

Although the "Garbage-First garbage collector" would be quite useful for Clojure, here I confirming that the new "G1" garbabe collector is "still in beta" at least for a "comparative use case" (using velocity/groovy/jPython in Xwiki, but not Clojure).

Is there something special about haskell, or could "verifiability announcements" happen for purely functional Clojure programs too?
