Hi guys!

...

How can I add method (I have /RBMethod/) to a class in code? I'm asking because existing method /addMethod:/ in /RBAbstractClass/ isn't working. Here is a piece of my code:

/method:= RBMethod for: class source: ('^ ', newName asString) selector: newName asSymbol. class addMethod: getter./

Thank you all. Problem is solved, I just used RBAddMethodRefactoring. Mark 2014-07-17 16:07 GMT+02:00 Baptiste Quide <baptiste.quide@inria.fr>:

I think you have to add a "RGMethodDefinition" or a "CompiledMethod". Obviously in a class methodDict the values are CompiledMethod.

No. Adding a method is not a refactoring. You should use RBAddMethodChange:

| model | model := RBNamespace new. (model classNamed: #Model) compile: 'asString ^ String empty' classified: #(accessing). model changes execute.

and the new method is recorded in the .changes file

Yes you need it because when doing code generation you cannot always assume target class is present. Besides using RB you can confirm through the NautilusRefactoring which is useful for massive changes: | model | model := RBNamespace new. (model classNamed: #Model) compile: 'asString ^ String empty' classified: #(accessing). (ChangesBrowser changes: model changes changes) openWithSpec Cheers, Hernán 2014-07-17 13:55 GMT-03:00 Esteban Lorenzano <estebanlm@gmail.com>:

Hi,

you do not need the RBNamespace mediation, just do:

Model compile: ‘method ...’ classified: ‘accessing’.

But wait. What happens here is that we are mixing concepts. 1) On one side, there is Pharo's class model (the one we program with) => classes, metaclasses, methods. Let's call them the *real* classes and methods. So if you want to add a method to your *real* class, you usually have to - compile a method - add it to the method dictionary of the class There are some helper methods that do all the work in one step, as mentioned by Esteban: myClass compile: someCode classified: aProtocolName. That, is what happens when you use the browser (Nautilus in our case). 2) On the other side, there is the Refactoring browser framework (that is, all classes prefixed as RB (except the AST nodes now)). The refactoring browser implements refactorings (renames of classes and methods, pushing up/down instance variables in a hierarchy, extracting methods into classes). Of course, to apply these refactoring it uses the model and API's provided by 1). But it's a completely different monster. That means, adding a RBMethod in a RBClass does not mean that you are adding a *real* method into a *real* class. That will not happen unless that change is inside a refactoring and you apply the refactoring. On Fri, Jul 18, 2014 at 3:43 AM, Ben Coman <btc@openinworld.com> wrote:

Thank you very much guys. I think, now I can understand what is going on with method adding:) Best, Mark 2014-07-18 12:09 GMT+02:00 Esteban Lorenzano <estebanlm@gmail.com>:

also you will still have an error if using the RBNamespace instead the direct method invocation, if class does not exist. So… I stand with my opinion :)

If you want to control existence, you could do something like this:

#Model asClassIfPresent: [ :class | class compile: 'asString ^ String empty' classified: #accessing ]
