Re: Defining own data types on top of Persistent ones

It doesn't use proxy, because I needed an additional method, which the proxy doesn't allow. However it is not very big and the methods are reasonable short to be easily understood. It turns any map given into a lazy map, which does not evaluate the value associated with a key until it is accessed. So this is maybe a good example of a modified data structure.

Defining own data types on top of Persistent ones
In #Clojure Rich mentioned today that we can define our own data structures on top of the existing ones. Maybe someone wants/needs his own version of vectors that rearrange automatically in some specific order or whatever. If I now want to add something that works nearly like lists, but a little bit different, and for which I can use all functions that work for lists, I will have to use a proxy. Chris Houser implemented a little helper tool: http://paste.lisp.org/display/67122#1 Now what I would like to see are some minimal examples on how to do that. Lists are a good candidate as they only have 6 methods which we need to implement: user> (show clojure.lang.IPersistentList) === #=clojure.lang.IPersistentList === [ 0] cons : interface clojure.lang.IPersistentCollection (1) [ 1] count : int (0) [ 2] empty : interface clojure.lang.IPersistentCollection (0) [ 3] peek : class java.lang.Object (0) [ 4] pop : interface clojure.lang.IPersistentStack (0) [ 5] seq : interface clojure.lang.ISeq (0) nil The numbers in parens at the end tell us how many parameters the methods should have. They have a hidden one more. We can magically use “this”. Here is what I tried: user> (defn make-lyst [& items] (proxy [clojure.lang.IPersistentList] [] (cons [obj] (cons obj this)) (count [] (count this)) (empty [] ()) (peek [] 5) (pop [] 6) (seq [] this))) As I found no examples yet, I was hoping this would return an instance of my own list type. (make-lyst 1 2 3) would print like normal lists: (1 2 3) And it would use the cons function of lists, dito for counting. (empty lyst) would return an empty IPersistentList, peek always a 5, pop always a 6 and seq the list object itself. But unfortunately (make-lyst 1 2 3) ==> java.lang.ClassCastException: clojure.lang.Proxy__5307 cannot be cast to clojure.lang.ISeq Any ideas how this should be done so that it will work? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: macro questions, "can't embed unreadable..."
It's possible but very ugly. You need to force the reader to make two passes over the code, using eval. Here's what I came up with: (defmacro declare-init [vecs] `(doseq v# ~(if (symbol? vecs) vecs (list 'quote vecs)) (eval (list 'def (first v#) (second v#) In use: user=> (declare-init [[a 1] [b 2] [c 3]]) nil user=> a 1 user=> c 3 user=> (def myvec '[[d 1] [e 2] [f 3]]) #=(var user/myvec) user=> (declare-init myvec) nil user=> d 1 user=> f 3 I do not recommend this approach, since debugging it can get hairy very fast. If you need to def global vars based on run-time data, chances are that you're Doing It Wrong. But it is possible.

problems with slime and emacs
Hello all,
I'm struggling to get slime and emacs to work together. I copied the
code from the readme included with swank-clojure, but am running into
an error. I'm sure it's something trivial that I'm missing. Here is
what I have in my .emacs copied from the various readme files.
;; clojure mode
(add-to-list 'load-path "~/.emacs.d/clojure-mode")
(require 'clojure-auto)
;; or if you use paredit, uncomment the following
;; (require 'clojure-paredit)
;; swank clojure
(add-to-list 'load-path "/Users/clk/.emacs.d/swank-clojure")
(require 'swank-clojure-autoload)
(swank-clojure-config
(setq swank-clojure-jar-path "/Users/clk/Documents/Development/
Languages/lisp/clojure_20080916/clojure.jar")
(setq swank-clojure-extra-classpaths (list "/Users/clk/.emacs.d/
clojure-extra")))
;; Add sbcl back in
(add-to-list 'slime-lisp-implementations '(sbcl ("sbcl")))
That results in the following error:
ad-Orig-error: Error: You must specify a swank-clojure-jar-path.
Please see README of swank-clojure.
I copied the code above from the readme. And yes, the path to the
clojure.jar is correct.
I'm using emacs 22 on OSX.

My guess for deployment would be to create a .jar file, which is distributed. The users put the .jar in their classpath and are able to load the library with require/use. For this to work the file layout has to follow the guidelines for namespace / filename translation, of course. I would use load only inside a ns to suck in different files for a namespace in case the implementation is split up. I would never use it to "load" a library. That's what require/use are for. To deploy a program one can create a Java class via gen-class, which contains a main function which "require"s the implementation of the program and starts the application running. In the MANIFEST.MF one can specify this class as Main-Class. So the user can do java -jar MyApp.jar to run the program. Just my 0.02€.

Pathetic n00b wonders how to deploy
Hi, I am totally new to Clojure, but not new to CL. I have been poking around a little bit and I have a couple questions: 1) does Clojure maintain the CL notion of a "running image" (ACL terms), or a "core" (sbcl terms)? For example, in ACL I can do (dumplisp), and I think sbcl has something called (save-lisp-and-die) .. 2) Does Clojure have anything similar to fasl files? It looks right now like the way to deploy a Clojure program is to deploy the source (.clj) files and (load) them, is this correct?

Memory usage when iterating over lazy sequences
Hi all, I'm just getting started with Clojure, and I've got a bit of a beginner's question regarding memory usage of lazy sequences. I have an array of data that is too big to fit in memory, so I thought I would be clever and process it in manageable-sized chunks. My instinct was to do this using loop/recur using 'take' to bite off the next chunk, and 'drop' to give me the remainder for the next recursive call. Here's a contrived example: ;; Process the list one chunk at a time (defn do-something [biglist] (loop [rest (drop 1000 biglist)] (when rest (doall (take 1000 rest)) (recur (drop 1000 rest) ;; Lazily calculate our big data set and pass it along for processing (do (do-something (map (fn [n] (make-array java.lang.Character 10240)) (range 0 10))) nil) When I ran my code it very quickly ran out of memory and fell over. After thinking about it for a while I've realised it must be because my 'do-something' function call is hanging on to the head of the list, so as its elements are realised and cached it gradually eats up all my memory. Assuming my diagnosis is right, is there some sort of idiomatic way of dealing with this sort of issue? I suppose that if the JVM allowed for true tail recursion then this problem wouldn't arise?
