[Newbies] Re: Re: Growing image
Hi Norbert,
you may want to put one of your app names {seaside. magritte. magma} and
one of the class names into google search. The search result connects you
immediately to the collective knowledge of the Squeak community, example:
- http://www.google.com/search?q=weakarray+seaside
Besides of that, you can look for class references and find the guilty who
send #new or #new: to one of the classes.

Hi Norbert,
the tool is Smalltalk, just inspect
(((Smalltalk allClasses collect: [:each | each name - each
instanceCount
])
reject: [:each | each value = 0])
asSortedCollection: [:a :b | b value a value]) asArray
This gives # of objects per class, in a nice GUI :-)
Thanks, this is quite good. I have now a statistic like:
246565 WeakArray
241929 WeakKeyAssociation
179848 ByteString
171165 Array
159003 Association
130254 WeakValueAssociation
What is the best way to determine where this instances are
referenced. Do I have to use PointerFinder or Smalltalk
browseAllObjectReferencesTo: or is there better way?
thanks for your help, this goes also to Ramon and David.
You are very helpful, guys.
Norbert

[Newbies] Stop a script for a second
Hi together, I am new to this list. So perhaps I should introduce myself. I am 25 year old german student studying congitive neuroscience in Utrecht/Netherlands. I want to use squeak /etoys mainly for exploring and visualizing some ideas in a quick way. Right now I want to build a prototype for an experiment and think that this is a good project to learn a bit more about squeak. I want to program a sequence of objects appearing on different positions on the screen one after the other and later in a random order. A very dirty way to do so is just script doing something like. object1 show. script wait for 1000ms. object1 hide object2 show script wait for 1000ms. I know that this is a very basic question but couldn't find the answer, as I don't know what it is I am looking for. thanks a lot martin ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners

What you can do instead is this: script ticking once a second, for an object with a variable named i * increase i by 1 * Test i = 1 Yes: obj1 show * Test i = 2 Yes: obj1 hide, obj2 show * Test i = 3 Yes: set i to 0 - Bert - ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners
[Newbies] notation
I'm having trouble understanding the '' in some Smalltalk programs, Such as this, from Smalltalk By Example: MyClassdoThis array := Array new: 3. array at: 1 put: 2. I can understand that we are creating a new 3-place instance of Array, named array, and putting 2 in the first slot. But I don't understand what MyClass, , or doThis are doing. -- View this message in context: http://www.nabble.com/%3E%3E-notation-tf2729086.html#a7612000 Sent from the Squeak - Beginners mailing list archive at Nabble.com. ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners

(nil asTraitComposition) print it returns a MessageNotUnderstood dialog. (Object#doesNotUnderstand:) print it returns a System Window(3891), and a CompiledMethod dialog.

Re: [Newbies] notation
Dave normally is not part of a method definition. Just the what is after it. in the browser. is used by authors to give contextual information. Now in Squeak you can do Point#x to get the compiled method x of class Point but this is query the meta information of classes.

The is just a way of indicating that you're talking about a message name. In your example, MyClass is the class name, and doThis is the message name. You'll never actually enter the when defining a message, instead you'd put the code in the doThis message of MyClass in the browser.
