Re: [Pharo-project] Fame vs Magritte - Moose-dev

26 Sep 2010

Ok I see your point.
What would be nice is to see how you could have fame and the core of Magritte merged so
that 
we can use 
	Fame
	and 
	Magritte could be build/described using Fame
this way we could use Fame serialization 
	for famix
	but also magritte

So may be this is the time to have Magritte 3 based on pragmas and using Fame/magritte
core as Magritte3 Core

 I do not know what is your scenario?  
 I would like to edit models in the web browser with seaside components generated with
Magritte and save the models using Fame.

  Like generating magritte descriptions from the
Fame pragmas.  
 do you have an example?
 because you mean describing Magritte in fame?  
 I am just wondering why I must use two languages to describe a metamodel with
constraints.
 If I want to express a language structure I must use Fame (to have package, classes,
properties).
 If I want to add constraints I must use Magritte.
 But when I define Magritte descriptions, I feel like I rewrite the same stuff I did in
Fame (except for the validation part).

  Then we could imagine to have a generic editor
for a metamodel and serialization... (like in EMF)  
 fame already support the functionality of EMF.
 I think that Fame should stay a simple metametamodel.

 Yes, but it is still missing editing tools compared to EMF, or am I wrong ?

  I wrote a very basic piece of code that does the
transformation from Fame to Magritte in some very specific use case and that is something
that is definitely possible.

 What do you think ?  
 I do not know. what is your need?  
 I want to describe a language only one time and be able to use tools from Fame and
Magritte.
 So with a minimal amount of work, I get serialization, edition, validation, code
generation.

  here is my summary
 fame is a minimal meta meta model ( 4 or 5 classes): we use it describe other model (such
as Famix)
 based on fame you can load and save model. 

 Magritte is a meta data driven framework.
 you describe specific entity and the tools interpret it.
