Re: [Pharo-dev] Class syntax brainstorming

by Thierry Goubier

The build / partial object syntaxes are interesting in the way they could be integrated with RB in creating RB actions (RDAddClassChange / RBAddClassVariableChange / RBAddInstanceVariableChange) that could then be played on "build". Gives you a nice undo/redo capability and Epicea integration to boot. Also, it could be valuable to not completely build / install the class in some cases, and manipulate the abstract structure without compiling it.

Hi. My idea was to ask concrete metaobject for new object definition: Class <<< #MyClass superclass: #Object; uses: #MyTrait; vars: { #a. #b }; classVars: { #A. #B }; package: #MyPackage; tags: #(Core); layout: #MethodDictionaryLayout. for class side: Metaclass <<< #MyClass vars: { }. Or: Class classSide <<< #MyClass for trait: Trait <<< #MyTrait uses: #AnotherTrait; package: #MyPackage; tags: #(Core Traits) for trait class side: ClassTrait <<< #MyTrait uses: #AnotherClassSideTrait 2017-05-22 9:25 GMT+02:00 Luc Fabresse <luc.fabresse(a)gmail.com>: > "basic mechanics, only THIS one in the image!" > ClassDefinition new > superclass: Object; "optional.

Because #createClass can be also interesting message to get new class without affecting live system. And #install should be default version of #installInto: anEnvironment.

I'd also put in the pot a more declarative, less-smalltalkish-syntax approach: Class { name: 'A', superclass: Object, a: InstVar, b: InstVar, c: InstVar } Of course this could evolve. Some people will say that this is too verbose if you have lots of instance variables. I'd say that having too many instance variables is a code smell :) Guille On Mon, May 22, 2017 at 1:27 PM, Gabriel Cotelli <g.cotelli(a)gmail.com> wrote: > If we can get rid off the myriad of class creation methods count me in. :) > > I would do something like: > > ClassBuilder new > name: #A; > superclass: Object; > addInstanceVariableNamed: 'a'; > addInstanceVariableNamed: 'c'; > addBooleanSlotNamed: 'z'; > addClassVariableNamed: 'D'; > use: SomeTrait; > use: SomeOtherTrait; > beWeak "if you want a weak subclass"; > build > > With all of this optional.

If we can get rid off the myriad of class creation methods count me in. :) I would do something like: ClassBuilder new name: #A; superclass: Object; addInstanceVariableNamed: 'a'; addInstanceVariableNamed: 'c'; addBooleanSlotNamed: 'z'; addClassVariableNamed: 'D'; use: SomeTrait; use: SomeOtherTrait; beWeak "if you want a weak subclass"; build With all of this optional. If we can avoid to pass nil as superclass for the cases you don't have a superclass that would be good, maybe an specific method in the builder ?
