What happens is the following: 1. partition-by from core is created in the namespace. 2. partition-by is overwritten by the seq-utils version => warning <- now the reload happens. reload does not nuke the old version of the namespace. so the old bindings are still in effect. -> 3. partition-by is supposed to be overwritten by the core version. => error I think this is some special treatment for core.

Re: Problem reloading source file with imports
Thanks Robert. That makes a lot of sense and I was able to follow your advice last night and get my source file to reload successfully by adding ":only [indexed]" to my :use clause (because indexed was the only function that I was using in this case). The thing that still confuses me is that I can successfully load a source file that imports the whole of clojure.contrib.seq once (with warnings) but an attempt to reload that source file then fails - even if I edit the source file to remove the whole :use clause before reloading. That's weird but I'm working again and that's the important thing - thanks.

I ran into the same situation as Chris yesterday with clojure.contrib.seq-utils as well as with clojure.contrib.str-utils.

Re: Problem reloading source file with imports
Sorry, I was tired and didn't explain very well. Right now you have a "naked" (:use clojure.contrib.seq-utils) somewhere. You want to use partition-by, but that's already in core, so you might just get rid of the :use altogether. But maybe there are some other functions in seq-utils that you do want to use --- in that case, do (:use [clojure.contrib [seq-utils :only [functions you want]]]) or (:use [clojure.contrib [seq-utils :only []]]) to avoid stepping on core and also to document what you actually use. If you really want the seq-utils version of partition-by, then you can do: (:use [clojure.contrib [seq-utils :as whatever]]) whatever/partition-by And if you really want to replace the core version with the seq version without any namespacing, do (:refer-clojure :exclude [partition-by]) (:use [clojure.contrib [seq-utils :only [partition-by]]]) does that help? --Robert McIntyre On Mon, Aug 30, 2010 at 2:43 PM, Chris Jenkins wrote: > How would using the :only keyword help here?

Re: Problem reloading source file with imports
Thanks for the pointers you guys. I changed my code to this: (ns test.core (:use [clojure.contrib.seq :only (indexed)])) ... (indexed being the function that I was interested in) and it now works ok. I can reload the file as many times as I like. I must confess that I am rather confused by all this. When I was loading in the whole of clojure.contrib.seq-utils, it was perfectly possible to load partition-by once (albeit with a warning) but trying to reload the source file, causing partition-by to be loaded a second time, failed. Does that sound right?

This will prevent partition-by from being loaded form seq-utils in the first place. Nothing bad happens. Similar you can say (:refer-clojure :exclude (partition-by)]). This will prevent partition-by being loaded from core. Both solutions will work. However you will probably want to switch your code to use the core version of partition-by.

Re: Problem reloading source file with imports
How would using the :only keyword help here? Just to be clear, the problem here is that attempting to load my source file the second time fails (loading the first time having succeeded, albeit with a few warnings about replacing symbols from clojure.core), which makes it very difficult for me to use swank-clojure, for example, because I can't hit C-c C-k twice on the same file. Here is the failure when I try to load the file for the second time: java.lang.IllegalStateException: partition-by already refers to: #'clojure.contrib.seq-utils/partition-by in namespace: test.core (core.clj:1) So here's my main question: If I'm working in the REPL and I edit a file that I've previously loaded, how can I cause the file to be reloaded without hitting that error? If my .clj file doesn't :use any other clojure modules then reloading works fine but, if it imports anything, then the second (load-file...) fails.

Re: Problem reloading source file with imports
Yeah, they changed that from clojure 1.1 and it's really annoying --- as far as I know, your only options right now are to either select exactly which functions from seq-utils you want using the :only keyword, or if you really want to use the seq-utils version you can use refer-clojure and the :exclude keyword. Or, you can use the :as keyword in the :use form to qualify the import so that you don't actually replace anything. If you accidently get this warning and don't want to restart the repl you can do (ns-unmap 'your-namespace 'offending-function), fix the naked import, and reload. --Robert McIntyre On Mon, Aug 30, 2010 at 5:54 AM, Chris Jenkins wrote: > Since I switched to Clojure 1.2, I see an error message whenever I try to > reload a source file that imports anything.

Problem reloading source file with imports
Since I switched to Clojure 1.2, I see an error message whenever I try to reload a source file that imports anything. The error message is of the form " already refers to xxx", as though it is complaining that it can't import the same thing twice. For example, I have a minimal source file that looks like this: (ns test.core (:use clojure.contrib.seq-utils)) I can load it (once!) into the Clojure REPL successfully: $ java -cp lib/clojure-contrib-1.2.0.jar:lib/clojure-1.2.0.jar clojure.main Clojure 1.2.0 user=> (load-file "src/test/core.clj") WARNING: partition-by already refers to: #'clojure.core/partition-by in namespace: test.core, being replaced by: #'clojure.contrib.seq-utils/partition-by WARNING: frequencies already refers to: #'clojure.core/frequencies in namespace: test.core, being replaced by: #'clojure.contrib.seq-utils/frequencies WARNING: shuffle already refers to: #'clojure.core/shuffle in namespace: test.core, being replaced by: #'clojure.contrib.seq-utils/shuffle WARNING: reductions already refers to: #'clojure.core/reductions in namespace: test.core, being replaced by: #'clojure.contrib.seq-utils/reductions WARNING: partition-all already refers to: #'clojure.core/partition-all in namespace: test.core, being replaced by: #'clojure.contrib.seq-utils/partition-all WARNING: group-by already refers to: #'clojure.core/group-by in namespace: test.core, being replaced by: #'clojure.contrib.seq-utils/group-by WARNING: flatten already refers to: #'clojure.core/flatten in namespace: test.core, being replaced by: #'clojure.contrib.seq-utils/flatten nil If I try to reload it then I see an error message: user=> (load-file "src/test/core.clj") java.lang.IllegalStateException: partition-by already refers to: #'clojure.contrib.seq-utils/partition-by in namespace: test.core (core.clj:1) user=> This error message is seen even if I edit the source file and remove the (:use ...) clause and then try to load the file again. Anyone have any idea what is going on? I didn't see this behaviour in Clojure 1.1 and it would be nice if I could find a way to reload files that I'm working on.
