special forms
Hi! It turned out that special forms are behaving strangely when you try to redefine them. For example, (defn def [ more] (println smth)) but when you try to use this function you'll got unexpected behavior. (def 5) - you'll got an exeption There is another situation when you use let. (let [def 5] (def e def)) In my opinion, this situation must be resolved. For example it is possible to 1) prohibit such definition 2) allow redefining keywords in namespaces -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: special forms
I thought I'd just share some thoughts on special forms... 2010/5/20 Konrad Hinsen konrad.hin...@fastmail.net You can't redefine special forms. What you define in your examples is the symbols that serve to identify special forms. But they indicate special forms only when used in the first position of a list that is evaluated. Everywhere else, they behave just like symbols, so you can use them to name vars or provide local bindings in a let form. One thing that this implies is that you cannot for example pass a reference to 'if'. (map if [true false] [:a :b] [:c :d]) ; throws java.lang.Exception: Unable to resolve symbol: if in this context (NO_SOURCE_FILE:1) Also, you can't circumvent this by using macros: (defmacro if-macro [pred tbranch fbranch] `(if ~pred ~tbranch ~fbranch)) ; The var #'if-macro now holds a real reference to something that does what if does. (map if-macro [true false] [:a :b] [:c :d]) ; throws java.lang.Exception: Can't take value of a macro: #'user/if-macro (NO_SOURCE_FILE:4) Special forms and macros are compile time constructs (all expressions are compiled when evaluated). The symbols that represent special forms are not resolved into vars at all. If special forms were a special kind of value, the var holding them could be rebound at run time, implying that the control flow structure of the code could be changed at run time. Just imagine what rebinding 'cond' to 'do' would do... This does not make a lot of sense in a compiled language, so the Clojure compiler simply looks for symbols with the right name, and unconditionally treats them as special forms. Special forms are a part and special case of the function invocation syntax. As Konrad said, the symbols identifying special forms only have special meaning in the function position of evaluated lists. Everywhere else they work as ordinary symbols. 2010/5/20 Аркадий Рост arkr...@gmail.com In my opinion, this situation must be resolved. For example it is possible to 1) prohibit such definition 2) allow redefining keywords in namespaces I agree that it would probably be good to make the use of one of those symbols outside the function position of an evaluated list an error (or at least emit a warning). // raek -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Running Clojure scripts in Maven
Okay, yes, what you are asking is possible, and I know how to do it. Of course, to see the compiled artifacts on the classpath, you'll have to be running in a state that runs after they have been created. :-) This shouldn't be terribly hard to do, but it's a bit arcane. I'll see if I can make it happen in the next couple of days. In the meantime, I need a parameter name! Any suggestions? Mode 1: * Original plugin classloading. All scripts share the same set of variables (defs), as if all run from a single REPL, but they don't share the project artifact or any project dependencies. This mode runs fastest since Clojure only has to be inited once. * Isolated classloading. The scripts are isolated from one another, but share artifacts with the project. Thus not isolated at all. So what do I call it??? Clojure has to be inited for each execution, so this will be a bit slower. The other option is that I only make the second form of classloading available, but I also kind of like the ability to share state between scripts... which you would lose if I did that... -- You received this message because you are subscribed to the Google Groups Clojure group.

Instead, action functions just take a value (which just happens to be the agents current state) and return a value (which just happens to become the agents new state). Incidentally, for this reason you can also use built-in primitive functions like 'assoc' or 'merge' as agent actions, with no changes required. So, once you start focusing on writing a function that returns the value you want, instead of worrying about state change, chances are that you'll have less trouble with nil values ending up in the agent's state.

Re: Running Clojure scripts in Maven
How about two separate maven goals? One script goal that does the current behaviour and shares vars, and one execute goal that can run code from the project. I imagine the execute goal would usually be used to call a single function in the clj source files. To simply support this, the goal could optionally take an entryFn instead of source. The entryFn would be something like my.ns/main-func and would name a no-argument function to be called. - Geoff On May 19, 11:44 pm, Jason Smith ja...@lilypepper.com wrote: Okay, yes, what you are asking is possible, and I know how to do it.

Re: Strange protocol behaviour
Before anyone spends time investigating, this has been accepted as an issue: https://www.assembla.com/spaces/clojure/support/tickets/353 My workaround for now is to use reify in place of deftype. -Steve On 20 May 2010, at 13:43, Steve Purcell wrote: I'm loving protocols, but I keep having to restart my JVM to avoid a puzzling issue when changing protocol definitions. Here's the simplest way to reproduce the problem: Start with file protoproblem/proto.clj: (ns protoproblem.proto) (defprotocol Steps (one [x]) (two [x])) and file protoproblem/impl.clj: (ns protoproblem.impl (:require [protoproblem.proto :as proto])) (deftype ArraySteps [a] proto/Steps (one [x] (first a)) (two [x] (second a))) In the repl, everything works as expected: user (load protoproblem/proto) nil user (load protoproblem/impl) nil user (protoproblem.proto/one (protoproblem.impl.ArraySteps.

Accessing final methods of superclass using :gen-class
Hello,
I'm attempting to use some java classes in clojure, where I need
the clojure to be AOT compiled. I'm running into trouble with
accessing final methods in the superclass of genclass. Some code:
--= Hello.java =
package com.example;
public class Hello {
public void hello() {
System.err.println(Hello, World!);
}
protected final void yo() {
System.err.println(Yo, World!);
}
}
--= HelloWorld.clj =--
(ns com.example.HelloWorld
(:gen-class
:extends com.example.Hello
:methods [[go [] void]]
:exposes-methods {yo yoSuper}))
(defn -go [this]
(.yoSuper this))
In this case I cannot access the protected final void yo() in the
Hello class with the clojure code. Now I'm not trying to override the
method myself, but is the :exposes-methods doing so under the hood ?
If so how do I get around this ?
Thanks for your help,
Edmund

Re: Running Clojure scripts in Maven
Now that I've had more time to think about it, I think your original idea should be the default, and only, behavior. Scripts should be able to access dependencies of the project, and, if possible, the compiled project classes as well (available after they are compiled). The code I checked into /trunk works this way, or at least it seems to. :-) This will require some new documentation, but it's ready to try (for now, you'll have to check out the code and build it locally). -- You received this message because you are subscribed to the Google Groups Clojure group.

It's on my list of things to do too (I just got an mp3 player that runs Android 1.6 and I'm going to start with Remvee's Hello World example). Me as well, except the Android SDK doesn't run on any of my native desktops, so I'm going the longer way 'round...

IIRC, there are two issues: both reflection and GC - which Clojure tends to use heavily - are slow on Dalvik. Possibly Froyo will help with that. mike -- Mike Meyer m...@mired.org http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information.

Long as keys in hash-map
I tried to use Long keys from the java.io.File/length method in a hash- map and failed to retrieve values using them. sorted-map is fine. The doc says hash-maps require keys that support .equals and .hashCode. Doesn't Long support those or am I missing something else? -- You received this message because you are subscribed to the Google Groups Clojure group.

Perhaps you could post a code snippet that shows the problem.
Here's a snippet that shows it works:
Clojure= (def ml {(long 1) one})
Clojure= (ml (long 1))
one
To show you that a Long is really used:
Clojure= (class (first (keys ml)))
java.lang.Long
