Re: VimClojure v2.1.1 is released
thanks. I do grok, vim. the other point is less about what to do once it is all set up ... it's that setting up is a multi-step hurdle. That's what has been prohibitive for folks. The risk is sinking the time and ending up at some sort of dead end. For me, i had to hack like crazy, for example to get up through the the rlwrap point in one set of instructions. seems simple enough but compiling all the dependencies was a killer... required though in my case -- ports not working. So I was pretty much out of steam after 8 hours just as I was seeing all the VimClojure instructions. You are all right that it is a bunch of whining on my part, but remember that it's not just me. I represent a demographic.

You are all right that it is a bunch of whining on my part, but remember that it's not just me. I represent a demographic. The VimClojure instructions really boil down to building the jar and installing the Vim plugin. The normal way of extract the zip into .vim doesn't work because of the extra contents, which I - personally - don't want in my .vim. Having a local.properties is the only solution I came up with, which was reasonably simple. Similar for the contorted setup for the clojure.jar: ant somehow does not honor CLASSPATH. So the user has to specify the clojure.jar location manually. Tips from ant gurus appreciated. Note: if you don't provide a local.properties file Ivy is used. Then this is a non-issue, because the clojure.jar and the necessary parts of contrib are downloaded automatically. I just learned about user.home. So I can simplify also the .vim installation of the plugin. was mostly asking if that piece happened to have been done yet . . . . a vim analogue of clojurebox for Windows and Mac.

Multimethods derive
Hi, I would like to use multimethods by dispatching on keys of the variables (maps) in a way that I sometimes have constraints on only some of the arguments. In common lisp I would say (defgeneric foo (a b)) (defmethod foo ((a bar) b) ...) (defmethod foo (a (b baz)) ...) (defmethod foo ((a bar) (b baz)) ...) This would mean that I have also defined methods for calls when (for example) `a' is an instance of `bar' and `b' of anything but `baz'. How can I achieve something like this with multimethods? I could define a relationship like (derive :bar :anything) (derive :baz :anything) and then do (defmulti foo (fn [a b] [(:somekey1 a) (:somekey2 b)])) with (defmethod foo [:bar :anything] [a b] ...) (defmethod foo [:anything :baz] [a b] ...) (defmethod foo [:bar :baz] [a b] ...) This seems to do the trick... but is this really the way to do it? If it is, it would be very useful to have something that is the ancestor of everything (like T in common lisp).

This has been thought about, at least: http://clojure.org/todo I think the question is... what should the universal ancestor be? For classes, it's java.lang.Object. But derive allows you to create relationships outside the Java class hierarchy. So for now, defining your own root ancestor is the way to proceed. -Stuart Sierra --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Clojure group.

Re: Threadring Benchmark
So I got a chance to do some tweaks to the clojure code and run the benchmark. I also used the approved (not alternative) version of java code for comparison. I must say I am impressed with the clojure agent performance. The previous implementation results for 20,000,000 hops was: java: 27.14 sec, 92% cpu scala: 190.78 sec, 183% cpu clojure: 215.26 sec, 134% cpu The new results are: java: 33.56 sec, 94% cpu scala: 191.08 sec, 177% cpu clojure: 77.01 sec, 91% cpu The tweaks to clojure code were minor. Basically, coercing hops to (int hops) and using (neg? hops) instead of =.
