Re: checking if a method is defined
Hi, as others said: to check that a protocol function exists you can use resolve as with every other function. If you wanted to know, whether a type participates in a protocol directly, you would check whether it implements the protocol's interface . user=> (defprotocol Foo (foo [this])) Foo user=> (defrecord Bar [] Foo (foo [this] :foobar)) user.Bar user=> (instance? user.Foo (Bar.)) true If you wanted to know whether the protocol is extended to this type in general you would use satisfies?.

Re: using contains? on transient collections
It is the expected behavior for everyone who has ever gotten burned by this bug :) Seriously though, this has come up several times over the last couple of years. I remain baffled that this has never been fixed (at least not as of 1.3). There are two ways this could potentially be fixed. On the one hand, transients could be made to implement more of the interfaces they are expected to implement. On the other hand, contains? could be modified to return a meaningful error rather than false when passed something that doesn't support that interface. Or better yet, both of these fixes would be a good thing. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

"fullName" is easier because it gets interned in the current namespace:
user=> (ns-interns 'user)
{fullName #'user/fullName, ->Person #'user/->Person, Named #'user/Named}
user=> (resolve 'fullName) ; no leading dot
#'user/fullName
For the fields in types you'll need reflection:
user=> (use 'clojure.reflect)
user=> (pprint (:members (reflect Person)))
#{ ... some stuff deleted...
{:name firstName,
:type java.lang.Object,
:declaring-class user.Person,
:flags #{:public :final}}
{:name lastName,
:type java.lang.Object,
:declaring-class user.Person,
:flags #{:public :final}}
... some other stuff deleted...

using contains? on transient collections
Hey everybody,
I did the following
(contains? (transient {:a 10}) :a)
and it returns
false
while doing (:a (transient {:a 10})) returns 10
Is this expected behaviour. Using clojure-version 1.2.1 (I know it is old
.. )
Thanks,
Sunil.

There may or may not be a Java class (including a deftype, defrecord, definterface, or defprotocol) with a .foo method, and any particular such class may or may not have a .foo method. You can check if a specific class or object has a .foo method though, using reflection. With an object, use (.getClass thingy) to get the class. Given a class, you can probe it using various methods of java.lang.Class to see if it has methods with particular names and/or signatures. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Clojure 3.1 and Contrib(s)
You need to include individual jars in your eclipse project dependencies if you want to benefit from the integrated REPL of the ccw eclipse plugin. The next ccw major release will have leiningen and eclipse project class path synchronization using the dependencies listed in your project.clj file if it exists. Meanwhile, synch your project depencencies with lein's dependencies manually. When you create a clojure project using ccw, it will put in it the clojure 1.2 and the monolithic contrib in the project itself and on its classpath. Just remove them from the project classpath and folder, update your project.clj to add the necessary dependencies, run lein deps at the root of the project then update your eclipse project classpath from the lib folder by selecting all the jar files there. Of course if you change dependencies, you will have to resynch them in your eclipse project classpath but in does not occur often in a project lifetime. Sinçe eclipse will complain if a jar file is missing, it's easy to spot the moment when it will get out of synch.

Re: Clojure 3.1 and Contrib(s)
Using eclipse to edit files is OK but *don't use it manage your dependencies in Clojure.* You should use leiningen to manage additions to your project. After starting a project with lein new projectName you can edit the project.clj file in the folder that is created. You'll see something like this (defproject projectName "1.0.0-SNAPSHOT" :description "FIXME: write description" :dependencies [[org.clojure/clojure "1.2.1"]]) To add libraries to the project, add values to the vector under dependencies such that each new library is in [] brackets and has [library-name "version"] So for instance, to add debug-repl (defproject projectName "1.0.0-SNAPSHOT" :description "FIXME: write description" :dependencies [[org.clojure/clojure "1.2.1"] [org.clojars.gjahad/debug-repl "0.3.1"] ; library-name in this case is org.clojars.gjahad/debug-repl & version is "0.3.1" ]) To change it to clojure 1.3.0, change the version next to org.clojure/clojure to 1.3.0 (defproject projectName "1.0.0-SNAPSHOT" :description "FIXME: write description" :dependencies [[org.clojure/clojure "1.3.0"]]) After changing org.clojure/clojure to 1.3.0, the rules are the same for adding dependencies. Clojure 1.3 doesn't actually use the contributions library anymore. Each contribution is now in it's own library. You can read this for info on what to include for different libraries. http://dev.clojure.org/display/design/Where+Did+Clojure.Contrib+Go On Wed, Feb 29, 2012 at 6:53 PM, Lawrence wrote: > Hello, > > I have clojure 1.2 and eclipse, with contrib, running together, but I > don't understand how clojure 1.3 and eclipse integrate with the > contributions.

Re: swank-cdt: Using Slime with the Clojure Debugging Toolkit
I'm sorry, the context of the message was not included. It's a reply to a
thread in April 2011.
I have converted to Emacs and am using swank! Hooray!
Now, I want to use swank-cdt but I have this problem.
After installing swank-clojure 1.4.0 with lein, I run (use 'swank.cdt) in a
repl and I get this error:
http://pastebin.com/Qr1usmDa
(Ignore line 1 about cake. I don't know how that got there.)
If you search the mailing list for errors with core/swank-worker-thread-name
It's basically recommended to switch to cake over leiningen but cake
doesn't work anymore :(
This is because OSX does not have tools.jar. Instead it has classes.jar.
This has something to do with running the JRE instead of the JDK.
Is there anything I can do on OSX Lion to resolve this issue?
Thank you for your time & please excuse my sending this twice. I wanted to
provide some context.

Re: swank-cdt: Using Slime with the Clojure Debugging Toolkit
I'm having the same issue on OSX with leiningen.
Unfortunately, it appears the cake project has been taken down so I cannot
use it to resolve the tools.jar problem.
http://releases.clojure-cake.org/cake gives a 404
The error I'm getting when I do (use 'swank.cdt) can be seen here

Clojure 3.1 and Contrib(s)
Hello, I have clojure 1.2 and eclipse, with contrib, running together, but I don't understand how clojure 1.3 and eclipse integrate with the contributions. It seems like it's simplily a matter of getting a contrib from github and what? running it through lein and using the jar file? adding the source to the project source? Normally with a java project I would just compile the library and add it to the eclipse class path, but that does not seem to work. Can anyone point me to an explanation on how to add a contrib to a project when using eclipse? thanks, Lawrence -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Bret Victor's live editable game in ClojureScript
Hi Bost, I think you may have actually missed the point in the video :) There's no pausing necessary - if I made the guy move on his own and changed his speed, you'd see it happen immediately. No modes here, aside from the projection exist. Likewise the only thing that gets recompiled is the code in the current scope, so it doesn't matter how large your project may be. Based on what I've heard so far, my implementation is actually more real than what Victor himself created and does everything except for the slider/color-picker in his demo. Cheers, Chris.

Re: for behavior difference between clojure and clojurescript?
Yes it's a known issue. Right now, = only works for two args. For the time being this is for performance reasons, a decent = is critical. The way ClojureScript currently handles multiple arity fns is quite unfortunate from a performance perspective - it uses the JavaScript arguments object. This results in an order of magnitude slow down for function calls on V8 as well as JavaScriptCore. I think we need to resolve this first before fixing =. There's already an open ticket in JIRA for both issues.

Re: Clojure in Python
>>How is performance looking so far? On CPython...well about as good as CPython is comared to Java. On PyPy however, we're pretty close to Clojure. Currently on a factorial example, clojure-jvm runs in about 15 sec. On clojure-py it's about 24 sec. But there's always room for more optimization. > I know it's early, but have there been any thoughts/plans around > interop and dependency management, possibly providing some sort of > bridge between lein and pip/easy_install/virtualenv? And is > performance the main drive here? Well first of all, the real main drive, is that I don't know Java libs nearly as well as Python libs. Secondly, there's a lot of cruft (imo) in Clojure that doesn't need to exist in a dynamic VM. For instance, there's no reason to new up something with (Foo. 1 2). In python objects are functions, so (Foo 1 2) works just fine. We have an alpha version of a shim built for integrating clojure with python. So in a python program you can do this; import clojure import examples.factorial # where examples/factorial.clj exists somewhere in the search path Clojure-py functions are python functions, and deftypes are classes, so interop is actually really good so far.

Re: for behavior difference between clojure and clojurescript?
i had a cljs repl up and running...here's the comparison and the emitted JS
ClojureScript:cljs.user> (= 0 0 0)
true
; js => cljs.core._EQ_.call(null,0,0,0);
ClojureScript:cljs.user> (= 0 0 1)
true
; js => cljs.core._EQ_.call(null,0,0,1);
ClojureScript:cljs.user> (== 0 0 1)
false
; js => (function (){var and__3546__auto4873 = (0 === 0);
if(cljs.core.truth_(and__3546__auto4873))
{return (0 === 1);
} else
{return and__3546__auto4873;
}
})();
ClojureScript:cljs.user> (== 0 0 0)
true
; js => (function (){var and__3546__auto4879 = (0 === 0);
if(cljs.core.truth_(and__3546__auto4879))
{return (0 === 0);
} else
{return and__3546__auto4879;
}
})();
So...looks like it's just = vs == (or even ===)

Hi, You should be using == for comparison between numbers. (for [a [0 1] b [0 1] :when (not (== 0 a b))] [a b]) has the same results between clojure and clojurescript.

I am quite new to clojure and maybe you can tell me where my problem is or if my assumptions that there might be a problem could be correct.

checking if a method is defined
Hi, The behaviour of resolve for named functions seems pretty clear to me: (resolve 'xyz) returns nil (when xyz has not been defined). and (defn xyz [x] 1) (resolve 'xyz) returns #'user/xyz (when xyz is defined) However if I try to define types: (defprotocol Named (fullName [Named])) (deftype Person [firstName lastName favoriteColor] Named (fullName [_] (str firstName " " lastName))) Why do the following return nil? (resolve '.fullName) or (resolve '.firstName) What should I be using to check that the symbol .firstName and .fullName are defined in the current scope? (I am trying to write compile-time code the filters/selects undefined symbols from a chunk of quoted code. I'd like this to work for both function symbols and method symbols.)

Re: Cake with TextMate & RVM
Maybe it is that you haven't included the directory where the cake executable is in the text mate PATH. For instance, my PATH is defined as: /Users/jmgimeno/Local/cake/bin:/usr/bin because my cake executable is in /Users/jmgimeno/Local/cake and textmate needs /usr/bin for other things.

Specifying the error message on validation-error of a dynamic var?
Is there any way to specify the error message when using set- validator! with a dynamic var? In a situation like this: (binding [*my-var* -1] (foo)) I'd like to be able to throw a custom exception when they try to bind to a negative number. Using set-validator! like this, the Exception message is ignored: (set-validator! #'*d* (fn [x] (if (< x 4) (throw (Exception. "*my-var* can only be bound to a non-negative number")) true))) Instead the message you see at the REPL is: java.lang.IllegalStateException: Invalid reference state (NO_SOURCE_FILE:0) Is there a way to specify the error message on validation-error of a dynamic var?

[ANN] fobos_clj 0.0.2 and TinyWordSegmenter 0.0.5
Hi all, I'm pleased to announce the 0.0.2 release of fobos_clj (Supervised machine learning classifier called 'FOBOS')[1]. You can use support vector machine or logistic regression with this library. The learned model file is quite small, so you can use this library in your own application. Using this library, I also implemented my word segmentation library 'TinyWordSegmenter'[2]. I attached the model file for Japanese word segmentation, but you can train your own model for Chinese or Korean. thanks, Yasuhisa Yoshida [1]: https://github.com/syou6162/fobos_clj [2]: https://github.com/TrainingCamp2012/TinyWordSegmenter -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Google Summer of Code 2012 - any mentors?
Core has not submitted the application. The application process just opened Monday and goes until March 9th. There have been some leaders among Clojure/dev that have stepped up to organize things. Keep watching http://dev.clojure.org/display/community/Google+Summer+of+Code+2012 for more details. I said I would be more than happy to put my name on something that needs a single point of communication and submit the application if that's what's necessary. But honestly, with the community rallying behind this, I think things are moving along just fine. Having the community push this effort is more beneficial than having Core do it, except in the case that there is some part that is dependent on having an official organization like Core.

As an aside, the above is indeed almost valid Afrikaans :) and would

Yes, language-detect does a fuzzy matching-letter-frequency-count (the
non-scientific name for it) sort of algorithm in an attempt to quickly
determine the language, so for shorter text, it has a higher chance of
being incorrect (because there is less letter frequency to analyze). Give
it a try with a longer input string.
Additionally, you could adjust the :smoothing option for the string, or
pass in a map of probabilities in as a :prior-map to coerce it one way or
the other manually.

Static calls compile down to an "invokeStatic" at the bytecode level,
which means you need the details available at compile time. That makes
your only options "eval" or reflection.
If you don't mind using undocumented implementation details, clojure
has some nice reflection facilities included:
https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Reflector.java#L205
eval:
(defn invoke-static [class f & args]
(eval `(. ~class ~f ~@args)))
(invoke-static org.domain.test.My 'sBar x y)
Reflection:
(clojure.lang.Reflector/invokeStatic org.domain.test.My "sBar"
(into-array Object [x y]))

Re: Google Summer of Code 2012 - any mentors?
Another two ideas were added :) (Native Clojure and Code optimizer). Hoping readers will not mind for putting myself as mentor on one of them, but if there are better candidates, feel free to take it :) I did a little bit gcj + Clojure playing and I'm eager to see native Clojure without jvm.

Cake with TextMate & RVM
Hi, I'm trying to get Cake to work with TextMate. I've installed both the TextMate bundle and Cake, but when trying to evaluate a script: (print (+2 2)) -^ Ctrl-X I get "env: cake: No such file or directory" I'm using RVM, so have spent some time studying this thread that discusses the error: http://groups.google.com/group/textmate-clojure/browse_thread/thread/7d42a13f50c98fdd ... and my take-away from it is that one needs to have clojure-contrib installed (which I have, via Homebrew), then create a project folder with 'cake new' and declare clojure-contrib as a dependency. I've tried this: (defproject foo "0.0.1-SNAPSHOT" :description "TODO: add summary of your project" :dependencies [[clojure "1.2.1", clojure-contrib "1.2.0"]]) (println(+ 1 2 3)) but still get the error.

Call static java method specified at runtime
I have a java class with several static methods:
package org.domain.test;
public class My {
static public void sBar(String x, String y)
{ System.out.println("sBar "+x+":"+y); }
static public void sBaz(String x, String y)
{ System.out.println("sBaz "+x+":"+y); }
}
I'd like to execute these methods from clojure. The concrete method
will be specified at runtime.
test.clj:
(ns test)
(:import org.domain.test.My)
; this is what I need but it does not work:
(defn foo [f x y]
(. org.domain.test.My sBar x y) ;hard coded call of the
java static method sBar
;(. org.domain.test.My f x y)) ;compiler error
;(map #(. org.domain.test.My % x y) [f]) ;compiler error
;(apply (. org.domain.test.My f x y));compiler error
;(. org.domain.test.My #(f) x y) ;compiler error
)
; this works but it's ugly:
(defn bar [f x y]
(let [s (str "(. org.domain.test.My " f " " ; method sBar or
sBaz
"\"" x "\" " ; String x
"\"" y "\")")] ; String y
(load-string s)))
; the actual call on the REPL is quite ugly and (I believe) also quite
inefficient and error-prone:
(bar "sBaz" "aaa" "bbb")
Do you know how to write the foo function without using load-string?
Thx in advance!

Re: Bret Victor's live editable game in ClojureScript
Great work Chris but I think you missed exactly the most important point of Victor's talk. It's about being modeless! When you stop the game in order to change the speed you lose the dynamic aspect. In your case it takes ~ 2secs to "recompile & restart" but if you have a game with 10^6 LoC then it may take hours you see the result of the speed and color change! What Victor preaches and what clojure is about is being able change the program while it is running. So what is needed is a speed slider and a color palette somewhere on the bottom of the right screen where you can change the ball speed and color "on the fly" _while_ the ball is moving. This it the next - dynamic - dimension Cheers!

I'd mentor someone willing to do work on the literate programming version. See http://daly.axiom-developer.org/clojure.pdf http://daly.axiom-developer.org/clojure.pamphlet (src) Even more interesting... It appears that the ePub standard allows embedded javascript. So ideally we would like to manipulate a canvas to show the ideas. For instance, I'd like to see a digital book that had a canvas element that showed the red-black-trie evolve, potentially interactively. Even more interesting...

Re: Question about this little method I wrote
Hi Mike, If I understood your aim correctly, and if you accept changing the output of (combinations [[1 2]]) to ((1) (2)) instead of (1 2), which I think makes more sense,then the reduce function does the job in one line for you. (defn combinations [items] (reduce #(for [l % i %2] (conj l i)) [[]] items)) the same, wordier and maybe clearer: (defn combinations [items] (reduce (fn [output item] (for [o output i item] (conj o i))) [[]] items)) and if you really need the output to be a list of lists instead of a list of vectors, maybe something like: (defn combinations [items] (map seq (reduce #(for [o % i %2] (conj o i)) [[]] items))) Btw, I learned an awful lot about compact ways of doing stuff in Clojure by doing the exercises (and checking others' solutions) on 4clojure.com, which I warmly recommend.

Re: Workflow and development tools for ClojureScript One
Hi Karl, My emacs setup is also based on live coding. For ClojureScript One hacking, I use lein swank and slime-connect - for clojure. And for cljs, I use inferior-lisp. When I'm in a cljs file, I just disable the slime-mode, so it uses the inferior-lisp. ./Vijay On Sunday, February 19, 2012 9:17:28 PM UTC+1, Krukow wrote: > > I was wondering what a good workflow for working with ClojureScript > One would be. > > For regular Clojure, I use Emacs with swank-clojure (using Sam's Live > coding emacs, which is great for Emacs beginners, > https://github.com/overtone/live-coding-emacs).

Re: cld 0.1.0 - Clojure Language Detection
Awesome! I'm seeing some inconsistency though. Does anyone know why a
Bayesian classifier would produce such different results? Could it be
because of the short input text?

Can I use clojure's logo to write an article to a magazine?
Hi, I didn't find what license is owned by logo of Clojure and I would like to use it on a magazine article. I saw a conversation, not conclusive, in which Rich Hickey (or his brother) gives the permission for a guy but it wasnt clear about the current license that rule the logo. Do you have any ideas?

[ANN] mcache 0.2.0 released
Last week I released mcache 0.1.0, a protocol-based clojure library for memcached. This latest change contains significant changes, summarized here: 1. Renamed the functions, and got rid of the "cache-" prefix 2. Removed increment and decrement functions from the protocol, as these seemed like gratuitous wrappers. 3. Added a core.cache/CacheProtocol implementation, in addition to the spymemcached client extension. 4. Rearranged namespaces 5. Updated the documentation 6. The library has been uploaded to clojars, hence now can be used from leiningen, etc. Thanks to Jim Crossly for the suggestion to look into CacheProtocol. Also, Jim, I hope you don't mind that I borrowed your naming scheme for the put functions. :-) I'm using this library in my own project, so I expect to continue maintaining and updating it going forward. I hope it proves useful to others. As before, any feedback is greatly appreciated. Thanks, -Dave -- You received this message because you are subscribed to the Google Groups "Clojure" group.

How to submit clojure bug report?
I found a bug in Clojure core, and know its solution, question is how
to submit a bug report?
FYI here is the bug:
=> (.withMeta list {:a 1})
#
This is reporducable in Clojure 1.2 and Clojure 1.3
This cause of this issue is in:
svn/trunk/src/jvm/clojure/lang/PersistentList.java
with the static method:
public static IFn creator = new RestFn(0){
protected Object doInvoke(Object args) throws Exception{
if(args instanceof ArraySeq)
{
Object[] argsarray = (Object[]) ((ArraySeq)
args).array;
IPersistentList ret = EMPTY;
for(int i = argsarray.length - 1; i >= 0; --i)
ret = (IPersistentList)
ret.cons(argsarray[i]);
return ret;
}
LinkedList list = new LinkedList();
for(ISeq s = RT.seq(args); s != null; s = s.rest())
list.add(s.first());
return create(list);
}
};
The withMeta() method should be overriden from AFn where it is
throwing the UnsupportedOperationException. This is being done with
the EmptyList static class further down the file.
