Thanks Gary. With this I'm able to get :use to work correctly -- FWIW the part I wasn't getting right (again :-() was the association between the namespace names and the directory structure. In the context of your example I was doing something like (ns core ...) rather than (ns overtone-test.core ...), for a file in the same location. I now see that I can name it just core (or whatever I want) if I put it up one level, just in src/ rather than in src/overtone-test. FWIW I've been down a similar path and figured out something about the namespace/directory structure mapping before, in the context of some other tools, but forgot... I guess I still don't find this very intuitive.
One thing that I'd like to know more about: when you say "Start a JVM in this directory with the classpath set to contain and files in src or lib" I'm not 100% sure that I know how you mean to do that. I am starting a JVM in that directory by saying "cake swank", and this seems to work now that I have the namespace names and file locations matched up. But how? Is the classpath being set to contain files in src and lib automatically by cake? Where does one specify this? It's not in my project.clj or anywhere else that I see. So even though it's currently working it still seems mysterious. BTW also I still can't seem to get "load" to work... it never seems to find the files.... I'd sort of like to know how to do that, to help dispel more of the foggy classpath mysteries, but I guess that now that I can get :use to work I can have a reasonable workflow one way or another. -Lee On Jun 24, 2011, at 4:11 PM, lambdatronic wrote: > The way that cake and lein behave is generally this: > > 1) Search up the file tree starting from the directory in which cake > or lein is called until a project.clj file is encountered.
