Re: clojure-test-mode

How to :use a defrecord from another source file and namespace?
I'm having trouble writing code in one namespace that instantiates a type that is defined in another namespace. I have two source files: other.clj defines a function called my-fn and a type called huss: (ns my-project.other) (defrecord huss [x y z]) (defn my-fn [] (println my-fn)) core.clj can successfully call my-fn from the other file but I try to instantiate huss and I get an ClassNotFoundException (ns my-project.core (:use [my-project.other])) (my-fn) ; doesn't work... gives java.lang.IllegalArgumentException: Unable to resolve classname: huss (println (huss. 1 2 3)) What's the reason for this? Is it intended to work like this and what can I do in order to define a type in one source file (and namespace) and use it in another?

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.

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?

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?

Re: Suggest slime-redirect-inferior-output be default for Swank clojure
Seconded. I found this very confusing when I first started with Clojure. 2010/1/21 Alex Stoddard alexander.stodd...@gmail.com Hello, As detailed in Bradford Cross' blog, (http:// measuringmeasures.blogspot.com/2010/01/agony-of-clojurehadoop-logging- and-how.html) the rebinding of *out* done in the swank/slime repl can be very confusing to folk who don't already know slime. This is because so many java libraries output to stdout. And within Clojure it is very easy to have output happening on a different threads where *out* is still bound stdout which all goes to the *inferior-lisp* buffer (usually hidden) not the repl. The helpful advice given in comments on the blog post is to use slime- redirect-inferior-output. With that all stdout ends up in the repl buffer. A direct result of all the effort to make it very easy to get up and running with emacs/slime/swank/clojure is that many folk inexperienced with slime will be encountering it for the first time using clojure (like me for instance). Might I suggest that slime-redirect-inferior-output be the default for swank-clojure-project? That is much less surprising to newbies who don't yet know about *out*, thread bindings, and swank/slime's rebinding of *out* in the clojure repl.

Re: Clojure Box 1.1
Incidentally, I just tried Clojure Box 1.0 on the same machine and get exactly the same error message. Very odd.

Re: Clojure Box 1.1
Out of curiosity, what configuration do you have in place that's causing clojure.contrib.pprint to be loaded? I'm not sure - all I did was to install Clojure Box and then I immediately saw the error message when it started up. Do you know how I could learn more about the configuration?

Re: Clojure Box 1.1
I have managed to get it to work now. The solution was to ensure that the Sun JRE was on the system PATH, rather than the IBM one. The IBM JRE seems to have a problem with the class file clojure/contrib/pprint/PrettyWriter.class in clojure-contrib.jar ...whereas the Sun one doesn't. The next question is, how can we find out why this is? There would appear to be two possibilities: 1) The IBM JVM is rejecting a valid class file 2) Clojure is emitting invalid bytecode that the Sun JVM doesn't mind but the IBM JVM rejects. 2010/1/11 Chris Jenkins cdpjenk...@gmail.com Incidentally, I just tried Clojure Box 1.0 on the same machine and get exactly the same error message.

Re: A Clojure Highlife
Thanks for sharing this. Coincidentally, I just wrote my first Clojure program which was... an implementation of Conway's Game of Life :-) I took a different approach - I represented the board as a vector of vectors of integers (1 for alive, 0 for dead) and then implemented a new-board function that takes a board as an argument and returns the next generation of that board. It seemed the functional way to do it. I then create an atom whose state is a grid and repeatedly call (swap! board new-board) in order to move it through the generations. I'll copy the source to my little program at the bottom of this email. If anyone has any comments on the style or possible improvements then I would be very interested to hear them. I'm particularly keen to hear how close to idiomatic Clojure style it is (is there a Clojure equivalent of the adjective Pythonic?)

Setting *warn-on-reflection* such that multiple threads can see it
Hi, Is it possible to set *warn-on-reflection* such that it can be seen by multiple threads? I can't use def to define *warn-on-reflection* because it is defined in another namespace. I can use set! to change the value of the binding for one thread but this is not seen by other threads: (set! *warn-on-reflection* true) (.start (Thread. #(println *warn-on-reflection*))) ...prints false The reason that I would like to do this is that I'm writing a program that uses Swing and I'd like to see if reflection is used on callbacks that execute on the AWT event thread... ideally without having to figure out how to make Swing call my function that sets *warn-on-reflection* before it does anything else.
