Re: leiningen - a Clojure build tool
Lein is super easy to install and use! To demonstrate the ease of installation, the Installation part in README should say: 1. Download only one file: wget http://github.com/technomancy/leiningen/raw/master/bin/lein 2. chmod +x lein 3. ./lein self-install Thanks for the work.

Re: A Clojure Highlife
The m-surrounding-neighbors-seq function only memoizes sequences containing Refs surrounding a particular ref at (x,y). I do this to avoid the recalculation of the coordinates of the cells surrounding each cell. As I understand it, memoization caches return values for input values. For example, the the Ref for cell (3,4) has Refs at [(2,3) (3,3) (4,3) (2,4) (4,4) (2,5) (3,5) (4,5)] surrounding it. It is only memoizing a sequence of these Refs, once for each point in the grid, not for every grid. If it was indeed doing that it wouldn't take long before the JVM ran out of memory- the simulation is very unlikely to hit a cycle :) Use the clojure libs I include in the bundle on my website: http://www.solussd.com/wp-content/uploads/2009/11/highlife.zip --- Joseph Smith j...@uwcreations.com (402)601-5443 On Nov 16, 2009, at 8:24 PM, Jeff Heon wrote: Hi there, Unfortunately, I was unable to get it working. From what I gather, I'm using the wrong clojure.jar and or clojure- contrib.jar. Could you tell me which version of theses files you are using? Anyway, I was wondering about the memoizing of the function surrounding-neighbors-seq. It's memoizing for every grid, which I guess is good if the application hits a cycle, but if it doesn't, it will unnecessarily keep function results for passed grids. I'm not sure about the memoizing cache behavior, but if we bet for non- repeating grids, I think it might be better to dynamically memoize for each grid only. This way, memoizing information for passed grids will be GCed. I'm thinking about something like this. Remove the global def: (def m-surrounding-neighbors-seq (memoize surrounding-neighbors-seq)) Modify the two following count-living-neighbors and get-living- neighbors-seq functions to let a memoized version once for each grid: See http://paste.lisp.org/display/90541 Using a let and passing the local memoized function to count-living- neighbors felt weird, but it felt better than doing a binding.

Stack overflow while processing XML
I am processing a very large xml file, 13MB, using clojure.xml.parse and clojure.contrib.zip-filter.xml with clojure 1.0.0. The xml file contains information on 13000 japanese characters and I'm extracting about 200 or so. At its core it extracts a very small subset of elements using: (xml- kdic :character [:literal #(contains? kcset (text %))] node) Where kcset is a set of desired characters. My understanding of this is that it returns a lazy-seq which if I count-ed the length of the sequence it would return 200 (not 13000). But in practice it actually generates a stack overflow. At the end of this post I have a relatively short version of the program which throws the stack overflow. In this case it has a (count ...) call which causes the stack overflow. In the full program I tried a few variations like so: (dorun (for [knode knodes] (print-kinfo knode To try to get the information to print, but before it also reaches the end of list it also throws a stack overflow. I also have the stack trace at the end as well. Thanks!

Transforming a SeqMap to a Map
Hey guys,
I'm having some trouble finding a nice way to perform a map
transformation I need. I need to transform this:
[ {:a 1 :b 2 :c 3} {:a 4 :b 5 :c 6} {:a 7 :b 8 :c 9} ]
into this:
{ {:a 1 :b 2} 3 {:a 4 :b 5} 6 {:a 7 :b 8} 9 }
I wanted to use map, but each f in map only returns one value, so I
couldn't figure it out. Here is what I have now:
(def result (ref {}))
(for [item coll]
(dosync (alter result assoc (dissoc item :c) (item :c
; result should now have correct value
I also wrote a recursive version to build the map without using a ref,
but I feel like I'm missing a simpler way..

Thanks. I got it working with the bundle. Arghh, I realized about half an hour after posting that I had misunderstood m-surrounding-neighbors-seq. I withdrew my post from the Google group, but like they say, nothing vanishes without a trace ;) I had not realized that since the grid is made out of refs, and since the refs themselves do not change, that the grid will always be equal to itself and thus not generate new memoization values even if the values inside the refs do change. These days it seems that not matter how long I think about a reply, and no matter how many times I reread it before posting, I'll find an error in it just after posting it 8p -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Clojure Terracotta - TIM
Thanks for your feedback. I was able to get it to work again and pushed some minor changes to the git repo. I downloaded Terracotta 3.1.1, and followed the instructions in the tim-clojure-1.0-SNAPSHOT/example/README. I ended up uncommenting all of the code in ClojureTerracottaConfigurator.java. I believe I had commented it out, because some of the replacement classes were not necessary anymore, and I was going to trim it down to the essential replacements, but I never finished the work. The error you are experiencing might be because of one of the outstanding issues. A non-portable class cannot be used as a root binding for any Var. As I mentioned before, I have an idea for a workaround, but have not pursued it as yet. If you'd like to help, then let me know.

Re: JScheme
There are other lisps (including schemes) but the three I have some experience with are JScheme, SISC, and Clojure. Based on that I would answer it this way... * Use SISC if you want a full implementation of Scheme on the JVM. (It's been reliable in the past but I have not used it for a couple of years - it may no longer be actively supported.) Speedier but more compliant and more complex than JScheme. * Use JScheme if you want a Lisp or Scheme-ish language, mostly for writing Java-esque applications in Lisp. (Again it has been a while, worked well for me in the past, and I don't know it's current support level.) * Use Clojure if you want a Lisp or other mostly functional and/or highly concurrent language for the JVM, under active development, etc. So far I have found its Java interop to be at least as expressive as JScheme's. But I would say use JScheme if you just want a traditional Lisp language that can use Java - the shift to Clojure's mostly functional style is more dramatic than that of JScheme's.

Re: SLIME REPL broken
You can still use slime-fancy and the arglist display feature by just disabling autodoc mode like this: (setq slime-use-autodoc-mode nil) (slime-setup '(slime-fancy)) On Nov 18, 11:26 am, Constantine Vetoshev gepar...@gmail.com wrote: On Nov 17, 2:52 pm, David Nolen dnolen.li...@gmail.com wrote: Thanks for pursuing this so adamantly :) For a long time (more than a year) it was possible to use SLIME tip. It would be great for that to continue. You can still use SLIME; just avoid the slime-autodoc contrib. Use (slime-setup '(slime-repl)) to initialize SLIME. At least, this works for me. Make sure you don't use (slime-setup '(slime-fancy)), because slime-fancy includes slime- autodoc. You lose the nicer minibuffer function argument display, but at least the basic environment works. -- You received this message because you are subscribed to the Google Groups Clojure group.

Double-clicking a target instantly runs it. Debugging (stepping through breakpoints etc) is something that may be hard to do from command line, especially for a large code base.

Re: Missing unsigned-bit-shift-right?

FYI: http://java.sun.com/docs/books/tutorial/java/nutsandbolts/opsummary.html I'm sure someone else will have a proper answer, but you could just create a class with a static unsignedRightShift method in Java and then: user= (defn [#^Integer val #^Integer shift] (Shift/unsignedRightShift val shift)) #'user/ user= ( 99 2) 24 Although you might want to call it unsigned-bit-shift-right instead for consistency with bit-shift-right. -- Michael Wood esiot...@gmail.com -- You received this message because you are subscribed to the Google Groups Clojure group.
