Maven vs Ivy (or Leiningen)

Hello. Clojure will use both Ant and Maven 2. (Maven 3 may be used in the future?) However, if we see management software world widely, there is Ivy. Could I ask you whether Ivy is well enough or not? ; Yes, there is another notable thing, Leiningen written in Clojure. ; It sounds interesting th

In the absence of #'record?, what's the safest way to tell whether a particular object is a true map or a record? - Brian Marick, Artisanal Labrador Contract programming in Ruby and Clojure Author of /Ring/ (forthcoming; sample: http://exampler.com/tmp/ring.pdf) www.exampler.com, www.exampler

records, metas, and type checking

If we try to write: (defrecord Point [#^double x #^double y]) then create them as follows: (Point. "sth") we've got java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Number (NO_SOURCE_FILE:0) and this is OK, but If we put: (defrecord vect2 [#^clojure.lang.IPersiste

Help with java conversion

I'm converting the java code examples in Killer Game Programming in Java by Andrew Davison to Clojure and am having great fun doing it. But I've hit wall where I can't seem to get the code to work. The following code moves an animated gif strip to a java array: public BufferedImage[] loadStripI

Re: Help with java conversion

If you're setting values in an array, use aset: (dotimes [i number] (aset strip i (.createCompatibleImage gc width height transparency)) ...) If you want to get a value, use aget: (let [stripGC (.createGraphics (aget strip i))] ...) Hope that helps, Justin On Jan 21, 11:07 am, WoodHacke

Re: Overriding a java protected method and calling the super-class method from within

Accessing protected methods is a pain. You could do it with reflection, as Bill said. In gen-class, you need to add the `:exposes-methods` option to gen-class. This will make the protected method available as a public method, under an alternate name. For example, if you're extending Java class

Implementing destructuring without setting your hair on fire

Hi everyone, let's play a round of golf. I am currently implementing associative destructuring for ClojureJS while trying not to peek into clojure.core too often -- which wouldn't make things much easier since the 'destructure fn is a huge beast. After a few tries I've come up with the following

Unification

Hi, I've read a bit about clojure.core.unify ( http://blog.fogus.me/2010/12/14/unification-versus-pattern-matching-to-the-death/ ) I haven't gotten through PAIP yet, but I gather unification libraries enable logic programming? Is it true that unification is a superset of pattern matching? Mostl

Using private helper functions in a macro.

It *is* possible, and not just if the private helper function is run at macroexpansion time to massage forms for the macro. The macro *can* output code that invokes the helper at runtime, but it's awkward: user=> (ns foo) nil foo=> (defn- priv [x] (+ 2 x)) #'foo/priv foo=> (defmacro call-priv-1 [x
