Re: [Pharo-users] What's the correct way to create anonymous subclasses in Pharo?

by Igor Stasenko

Do you really need to create a meta? If not , then you can do just: newClass := Rectangle clone. newClass superclass: Rectangle; organization: nil; methodDict: MethodDictionary new.

What's the correct way to create anonymous subclasses in Pharo?

by Joachim Geidel

Hi everybody, I am attempting to create subclasses of existing classes at runtime. They must not be in their superclass' list of subclasses, because they have to be garbage collected when they are no longer needed. This is what I tried to create such a class in Pharo 1.0: newMeta := (Metaclass new) superclass: Rectangle class methodDictionary: MethodDictionary new format: Rectangle class format; yourself. newClass := (newMeta new) superclass: Rectangle methodDictionary: MethodDictionary new format: Rectangle format; setName: #MyRectangle; yourself. newClass new class == newClass "--> false" The result of "newClass new" seems to be an instance of Rectangle, not of newClass. The test at the end of the code snippet answers false. When I compile a new method in newClass and install it in newClass' methodDictionary, an instance will not understand a message with the method's selector. Almost the same code will do what I want in VisualWorks: | newMeta newClass | newMeta := (Metaclass new) superclass: Rectangle class; methodDictionary: MethodDictionary new; setInstanceFormat: Rectangle class format; yourself. newClass := (newMeta new) superclass: Rectangle; methodDictionary: MethodDictionary new; setInstanceFormat: Rectangle format; setName: #MyRectangle; yourself. newClass new class == newClass "--> true" Does anybody have an idea what the problem is and what can be done to circumvent it? Thanks in advance! Joachim Geidel

Mein Vorschlag ist wahrscheinlich ungewÃ¶hnlich. Ich mÃ¶chte es Ihnen trotzdem unterbreiten. Ich besitze eine kleine GmbH mit Schwerpunkt Entwicklung von Programmierwerkzeugen und eine BranchenlÃ¶sung fÃ¼r die Abfallwirtschaft. Wenn es Sie interessiert schauen Sie doch bitte einfach auf http://contfakt.q-software-solutions.de/ Was hat das nun mit Ihrer Ausschreibung zu tun. Es ist geplant diese LÃ¶sung auf eine webbasierte LÃ¶sung umzustellen. Und ich habe mich nach langem EntscheidungsprozeÃ dazu durchgerungen es mit Smalltalk abzuwickeln, hauptsÃ¤chlich weil ich: http://www.e-racuni.com/homepage/WikiPage?page=Home&lang=English gefunden haben. Diese Firma benutzt nicht gerade Seaside aber etwas Vergleichbares. Nun ja so wie ich das sehe sind Sie absolute Spezialisten aus diesem Bereich, somit hoffe ich, daÃ Sie mich vielleicht bei der Portierung unterstÃ¼tzen kÃ¶nnten. So wird derzeit an zwei Modulen gearbeitet. An einem EANV Modul (eine deutsche "spezialitÃ¤t" (elektronsiche abfallnachweisverfahren) und ich arbeite mich derzeit in das obige genannte Framwork ein um damit ein Waage Modul zu portieren. Nun ja es ist aber nicht festgelegt, daÃ ich hier nicht Seaside benutze. Wegen der derzeitigen unmÃ¶glichen politischen Entscheidungen in Deutschland, suche ich derzeit die MÃ¶glichkeit umzusiedeln. Die Schweiz ist dabei weit oben auf der Liste aber auch Neuseeland oder Australien. Ich habe aber mehrere Kunden auch in der Schweiz und sollte ich wirklich auswandern und meine GmbH behalten wollen, suchte ich nach Partnern die hier vor Ort den Support leisten kÃ¶nnten. Daher handelt es sich nicht um eine direktes nachfragen nach Ihrem Angebot, sondern ich suche eigentlich Gleichgesinnte fÃ¼r die Entwicklung von Web Anwendungen... WÃ¤re es eventuell fÃ¼r Sie interessant hier nach einer Zusammenarbeit zu suchen und/oder Ihr "portfolio" um eine Portierung der Contfakt Software auf Webtechnologien zu erweitern? WÃ¤ren Sie ins Blaue gedacht an einer Zweigniederlassung in AUS/NZ interessiert? Es ist zwar nicht direkt mit Ihrem CMS verbunden, nur kÃ¶nnte ich mir vorstellen, daÃ es auch eine Basis fÃ¼r eine Software im Bereich des Abfallindustrie oder auch Transportindustrie bilden kÃ¶nnte. Viele Anwendungen die derzeit noch "nativ" laufen dÃ¼rften von einem Baukasten fÃ¼r "betriebwirtschaftliche" Anwendungen interessant sein. Nur weiÃ ich selbverstÃ¤ndlich nicht ob das ein ansprechender Bereich fÃ¼r Sie wÃ¤re. Wenn ich Sie mit dieser Mail belÃ¤stigt haben sollte, bitte ich das zu entschuldigen.
