Hi Esteban, In the present model, the plant has a tree-like structure. It is a well suited structure, even for a dandelion since the leaves are connected on a shoot. The plant root system has a tree structure as well ! Thank you, Loïc Le 16/01/2019 à 13:52, Esteban Maringolo a écrit : This

Re: [Pharo-users] Transforming objects

Being a fan of DDD and Event Sourcing as I am, I'd implement your domain using Aggregates and Events. Basically, your aggregate (Plant?) would respond to external information (or based on a schedule) and as a result, new events are generated ("Flower sprung", "Plant died", ...). If only we had prop

Re: [Pharo-users] Transforming objects

Hi Richard, You are in the south hemisphere, so ! Temperatures are low here in France. Thank you for your comments. I agree that development is slow if you look at the plant every day, and in this case we perceive continuous changes. But in models, it might be convenient to define discrete sta

--- Begin Message --- Yes, due to the object layouts and strong connection of Object with VM, my idea can not be done that easily. I want to add some information (instance variables like OID [object id]) to some objects of any kind (some objects = persistent objects). I can do it with map (iden

[Pharo-users] LOOP book title mismatch

At http://books.pharo.org/learning-oop/, the title is "Learning Object-Oriented Programming, Design *with* TDD *in* Pharo" but the actual PDF has the title "Learning Object-Oriented Programming, Design *and* TDD *with* Pharo". So which title is correct?

Re: [Pharo-users] adding instance variables (data) to the Object class

I am having a little trouble understanding how adding instance variables to Object is supposed to work. Where would an immediate object like a SmallInteger *put* such variables? What does it even *mean* for 0 and 1 to have instance variables? Do you really want to give an extra word of storage t

Re: [Pharo-users] Transforming objects

This is a challenging modelling issue, life progress or any other dissipative/emergent structure are "restricted" by the boundaries of your objects (e.g. if you model a flock, and it divides into two flocks, and then merges again, which flock remains? Note: I wouldn't model the Flock at all). So i

Re: [Pharo-users] Transforming objects

It seems to me that in the real world, a bud does not get replaced by a flower nor a flower by a fruit, nor is there a definite point at which a thing stops being a bud and starts being a flower, and so on. It's summer now, but spring wasn't that long ago, and I enjoyed watching the imperceptible

Loïc, Am I correct in assuming you are thinking about a model in which a plant can have a growing and shrinking list of organs over time and some of them even have (a growing list of) stages? I am not an expert on the matter, but to me the stages idea sounds good. It even allows for historic
