A ring object can set a ring environment, if not it uses the default smalltalk environment without keeping a pointer to it. #environment: is call when adding elements (e.g. when adding a class to a package) to propagate the (ring) environment It won't mix, it will use the Ring environment (e.g. a RGNamespace) or the smalltalk environment > > Stef

May be we should just do it as in old = anotherMethodReference "Answer whether the receiver and the argument represent the same object." ^ self species == anotherMethodReference species and: [(self classSymbol = anotherMethodReference classSymbol) and: [(self classIsMeta = anotherMethodReference classIsMeta) and: [self methodSymbol = anotherMethodReference methodSymbol]]] On Aug 12, 2011, at 11:51 AM, StÃ©phane Ducasse wrote: > Another question > > > = aRGMethodDefinition > "This method look for equality of the key properties of the receiver" > > ^(super = aRGMethodDefinition) > and:[ self selector == aRGMethodDefinition selector ] > > why not category? and source pointer? > > S. >

[Pharo-project] formatting style

by StÃ©phane Ducasse

I know that you all have your own hyper cool view on formatting. =========================================== Now I would really like that we agree on the minimum put a space after a variable and before := stamp: anObject "stores an author alias and a timestamp" stamp := anObject instead of stamp: anObject "stores an author alias and a timestamp" stamp:= anObject =========================================== Put a space before method argument stamp: anObject "stores an author alias and a timestamp" stamp := anObject instead of stamp:anObject "stores an author alias and a timestamp" stamp := anObject =========================================== Put a space after ifNil: ifTrue: ....

Another question = aRGMethodDefinition "This method look for equality of the key properties of the receiver" ^(super = aRGMethodDefinition) and:[ self selector == aRGMethodDefinition selector ] why not category? and source pointer? S.

[Pharo-project] ring new version question

by StÃ©phane Ducasse

Hi veronica I'm reading your changes again and I have some questions: environment: namespace namespace = self class environment ifFalse:[ environment := namespace ] why that? is it because you want to have pointer to Smalltalk globals by default for your ring objects? You would be mixing RING and Smalltalk classes? Stef
