Re: [Pharo-users] Create a .exe application in Pharo 2.0

What you can do here, is using the preferences to automatically start your app when a pharo image is open :) Then your Pharo.exe+your image will turn into a Minesweeper :) Ben On 31 Oct 2013, at 15:01, Paolo Piccinelli <captain86(a)hotmail.it> wrote: > Hi Everybody, > > i'd like to know what can i have to do to create a .exe application/desktop application, after creating a Package with all the working classes in Pharo 2.0.

Ok. This explains, why just "doing" SequenceableCollection new is ok, while "printing" causes problems. Thank you for your explnation. > The question is: should there be an explicit error message when an > abstract class is instanciated, is that even possible ? This may be difficult, because the instantiation of a not abstract subclass normally /is/ an instantiation of the abstract super class, isn't it? And in Smalltalk we have no concept of abstractness in the language itself, but only by convention. Greetings, Michael

Now, the actual error happens in the environment (debugger, inspector, printString mechanisms): they see a collection and try to work with it, since it is an incomplete/degenerate one, things break/loop. The following does work for example: SequenceableCollection new isCollection. The question is: should there be an explicit error message when an abstract class is instanciated, is that even possible ? Sven

Hi Igor I have done that, but still gets an error, do I need to remove NativeBoost ?

Re: [Pharo-users] Strange behaviour of abstract method

by Bernat Romagosa

Just tried in Pharo 1.4, 2.0 and 3.0. It fails in all of them. The error doesn't happen when sending #add: though. Try doing SequenceableCollection new and the same thing will happen. 2013/10/31 Michael Paap <mpaap(a)netcologne.de> > Hello list, > > in our OOP course we noticed some behaviour of an abstract method, which I > cannot explain.

Strange behaviour of abstract method

by Michael Paap

Hello list, in our OOP course we noticed some behaviour of an abstract method, which I cannot explain. Maybe you can help me: If I do the following SequenceableCollection new add: 123 I would expect an Error. The method add: is not implemented in SequenceableCollectionbut inherited from collection, where it's only statement is self subclassResponsibility But in reality, Pharo seems to enter an endless loop, consuming more and more memory. Can someone please explain to me, what happens here? Greetings, Michael
