Re: About removing class side initialization

by Marcus Denker

For both #isAbstract and #initialize, one can understand both as cases where we have to use behavior for something that should actually be a kind o declarative property of the objects. - isAbstract This is a property of the class. - initialize This is a property of the Variable. Itâs really unfortunate to have to fall back on code execution for that. What the initalize does is to say âthe default value of this Variable is this literal valueâ or âsend this message to the new object to set the default valueâ Anything else that you could do in #initialize is IMHO bad style. We always are proud that âEverything is an Objectâ. But as soon as we talk about the language itself, Smallkers suddenly forget everything we know about objects: Everything has to be a Class or a Method ! there is no other way! We really need to try to free ourselves from this mindset and start to model our programs better. With fluid class defintions and First Class Variables, we can do this: Object << #MyClass slots: {}; sharedVariables: { #ClassVar => InitializedClassVariable default: 1 }; package: âMyPackageâ; (this works and even is correctly stored in GIT or even when filed out) Instead of #isAbstract, we can just tag the class as Abstract, we could add a method on the classBuilder: Object << #MyClass slots: {}; sharedVariables: { }; package: âMyPackageâ; beAbtract or have some way to specify properties Object << #MyClass slots: {}; sharedVariables: { }; package: âMyPackageâ; properties: {#abstract } There is even already a property API on class, but no support on the level of the class builder / class parser yet. And of course, we have to then make sure this is stored correctly in Git.

Re: About removing class side initialization

by Noury Bouraqadi

This is indeed an issue I'd like to see solved. Class initialization is just an instance of a more general isssue. In SUnit, defining abstract classes is dirty. The code often looks like this MyTestClass class>>#isAbstract ^self == MyTestClass In PharoJS we face the issue of class specific methods. Upon transpiling to JS, we want to perform some actions for some classes and not their subclasses. A possible solution is to introduce class specific properties through an extra-layer of metaclasses.

Great. I have the idea of Digital Twin applied to Software https://askoh.com/#DigitalTwinS I want to translate Smalltalk to a fast language like C++. Does Moose and Famix have the ability to do that?

Re: [ANN] New Success Story posted

Short answer: yes and yes longer answer: The migration was/is from GWT applications (therefore Java) to Angular Typescript. It was for a project with an industrial partner that is still using the Moose to migrate other GWT applications. The research was performed by Benoit Verhaeghe (in CC) who was later on hired by the company to continue the work. The migration tool is based on Moose and Famix meta-model. In this case creates a Java model of a GWT application, then from that it creates a model of the application GUI, and re-exports it in Angular/TS Using Famix and Moose means it can handle other languages. We did experiment from Spec to Spec-2 for example nicolas On 20/01/2024 06:57, Aik-Siong Koh wrote: > Was the migration from Java to Angular Typescript?
