Reminder General issues • This project concentrates on defining a graphical concrete syntax for a language, if the abstract syntax is given. • Tool a generic language editor • Part of TopModL project
12/20/2005
4
Reminder Define a language • Definition : • Abstract synthax : MetaModel • Concrete synthax : Graphical templates
Reminder ProBXS • Project of Fabrice Hong (Semester Project in Winter 2004) • Concrete syntax graphical edition tool • « SVG image becomes an editing tool » • Display representation based on SVG templates • DopiDom extension (dynamical behavior) 12/20/2005
6
Reminder DoPIDom • Tool to build interactive environnements, masking the concept of application from user point of view • Based on : DOM (documents) SVG (their representation) • DoPIDom defines the concept of component & defines the behaviour that each component can have (Consumable actions or queries) • DoPIDom also defines the concept of instrument & actions they can produce 12/20/2005

Reminder Exemple of interaction • Change the name of a state in statechart language
12/20/2005
10
Reminder Exemple of interaction • Component « State » can consume the action « changeName » because it implements the interface « Namechangable » • The interactor produces the action by clicking on the component and changing the name. => Our task now (rising synchronization) is to imforme the model that the name changed in the graphical representation.

Reminder Chosen technologies
ECore Kermeta Instructions
Augmented SVG 12/20/2005
13
Reminder KerMeta • What is KerMeta? • Metamodeling language • Defines • Structure of metamodel • Behavior of metamodel
• High level of abstraction • We don’t have to deal with the concept of repository • We just handle KerMeta’s object and operations.

Defining a new language • Definition of the language • MetaModel => • Templates =>
class Node { atribute c : color reference input : set Link[0..*]#side1 reference output : set Link[0..*]#side2 }
Kermeta2Ecore transformation
class Link { reference side1 : set Node[0..*]#input reference side2 : set Node[0..*]#output }

Kermeta2Ecore transformation • Supported by Kermeta • In eclipse environnement

Creating a new language MetaModel

(.kmt)
(.ecore)

require kermeta using kermeta::standard
class Node { atribute c : color reference input : set Link[0..*]#side1 reference output : set Link[0..*]#side2 }
class Link { reference side1 : set Node[0..*]#input reference side2 : set Node[0..*]#output }

Creating a dynamic instance • Ecore allow to create a dynamic instance of one specific element of the metamodel • In eclipse environnement

Handle the Model with Kermeta • One can handle the resource • Load it • Save it • Manipulate its elements (like a Dom tree) • Creating • Removing • Moving

Rising synchronization Interaction between DoPIDom & KerMeta • Call the KerMeta interpretor from DoPIDom • Handle KerMeta operations from DoPIDom • Keep synchronized graphical elements with their abstract representation

Rising synchronization • Add Kermeta instructions into SVG templates Allow multilanguage Recover tag and attributes
