Greg: your code works, if I go back to the original classpath. Thanks. The 2nd classpath I posted was purely out of desperation, I didn't think it was really going to work.
What your code implies to me is that for each namespace, there should be one source file that is sort of the 'master' file -- foo.clj in the case of my toy example. The other files in the namespace should use (in-ns). I'm going to experiment now with loading one of these subsidary files from another. Maybe the lesson will be that you aren't supposed to do that, we'll see. I wouldn't say that closure's documentation is barren per se. I've got "Programming in Clojure" and http://java.ociweb.com/mark/clojure/article.html, which are both helping a lot (plus clojure.org of course). Clojure is still pretty new, I'm sure the documentation will improve. I would say that the documentation does a good job on the lispy parts of clojure, but not so good of a job explaining namespaces, code organization, etc. On Fri, Feb 5, 2010 at 5:09 PM, Greg <g...@kinostudios.com> wrote: > Mike, I'd say this is not your fault.
