eTrice is a project under the Eclipse Modelling Domain intended towards implementation of the ROOM modelling language. This project titled "Diagram Layout in eTrice with KIELER" aims at improving the Diagram Visualization in eTrice by providing a new feature of automatic lay-outing of ROOM diagrams in it's graphical editors. The complete infrastructure for carrying out the automatic layout is provided by the KIELER project, which provides a huge support for configuration and execution of layouts in various graphical editors in eclipse (eg: GMF and Graphiti based editors).

A brief description of all the major technologies involved in this project is as follows :-
- ROOM - ROOM(Real Time Object Modelling) is both an object-oriented modelling language and a development method specifically designed for dealing with large distributed real-time embedded software systems characterized by event-driven or, reactive behaviour.
- eTrice - eTrice is a project under Eclipse Modelling domain which provides an implementation of the ROOM modelling language in the following way:
- It provides a textual editor to express the ROOM models in a easy and clear DSL (made in Xtext).
- It provides two graphical editors(made in Graphiti) to diagrammatically represent and edit the structure and behaviour (hierarchical state machine) of the actors involved in the model. These diagrams just contain layout information and any changes made in the graphical editor are reflected in the textual model.
- It provides code generators for the ROOM model in a variety of target languages like Java, C, C++.
- It provides Runtimes which give basic infrastructure like messaging and debug support.which is implemented by eTrice
- The eTrice is the base project for this proposed development.
- Graphiti - The platform in which graphical editors of eTrice are built
- KIELER - The Kiel Integrated Environment for Layout Eclipse Rich Client, or short KIELER, is a research project about enhancing the graphical model-based design of complex systems. The basic idea is to consistently employ automatic layout in all graphical components of the diagrams within the modeling environment. This opens up new possibilities for diagram editing, browsing, and dynamic visualizations (e.g. for simulation runs). Hence the focus of this project is the pragmaticsof model-based system design, which can improve comprehensibility of diagrams, improve development and maintenance time, and improve the analysis of dynamic behavior.
- The KIELER project provides the complete infrastructure for performing automatic layout within the proposed development.
- Xtext - The framework defining the DSL used for textually representing models in eTrice
The deliverables of the project would be :
- Two fully-functional graphical editors for eTrice with automatic lay-outing features for diagrams using the KIELER framework :
- one for modelling hierarchical Structures of actors
- another for modelling hierarchical State Machine Diagram (behaviour) of actors.
- User will be provided the following methods to use the feature:
- A toolbar and menu action to trigger layout on the active diagram.
- A "Layout" view for layout option configuration.
- User Documentation for how to use these features in both the editors.
- Developer's Documentation for explaining the current implementation ( to facilitate any changes to be made in future and re-usability of the present code )
- Resources (proper interfaces) for further extending the features of the editors by using the KiVi, KSBasE and KLighD Frameworks (provided by KIELER).
- Documentation for the above resources for facilitating the extension.
- Tests for proving bug-freeness of the developed feature.
Phases of Development
The project implementation will be divided into three major phases :
- Integrating KIML with present graphical editors, which is the basis for all further improvisation and enhancements.
- Designing of the interaction mechanisms such that the layout is performed automatically in certain situations, eg. making of a new actor and binding it with another in Structural Editor (or) defining a new state and connecting it to others in Behavioural Editor will automatically trigger lay-outing.
- Investigating and Implementing KLighD into the eTrice editors. If time permits the other two KIELER sub-projects (namely KiVi, KSBasE) will also be investigated.
The following calendar shows the details of the various tasks to be completed and the deadlines during the project tenure :-
Basic Tentaive schedule
A superficial schedule of the project would be as follow:
- Before 2 May : Preparing the project Wiki and improving the understanding of the implementation process.
Before the beginning (Community Bonding Period) -- completed
- 2 May - 21 May : Gathering the background knowledge as indicated by above sections(Background), Detailing of the schedule to make it more rigid and easily track-able.
I Phase (Integrating KIML with present graphical editors) -- completed
- 14 May - 24June :
- Implementing the transformation of Hierarchical State Machine Diagrams to KGraph meta-model instance.
- Implementing the transformation of KGraph instance to Hierarchical State Machine Diagrams.
- Implementing the transformation of Actor Structural Diagrams of ROOM models to KGraph instance.
- Implementing the transformation of KGraph instance back to the Structural Actor Diagrams and combining the above implementations to complete phase I with tests.
II Phase (Designing of the interaction mechanisms) -- in progress
- 25 June - 7 July :
- Gathering information about the required situations for automatic layout triggering
- Implementing layout triggering for the gathered situation
- Some more interaction mechanisms will be implemented after the Mid-Tern Evaluation
- 7 July - 9 July : Combining all implementations from Phase I and Phase II for preparing a stable version for mid-term evaluation.
- 9 July - 13 July : Mid-Term Evaluation
- 14 July - 15 July : Feedback reception and changes if required.
- 16 July - 22 July :
- Gathering 'more' information about the required situations for automatic layout triggering
- Implementing layout triggering for the gathered situation
- [ 23 July : Return back to the my institution (holidays end) ]
III Phase (Investigating KLighD and providing a basic integartion into the editors)
- 23 July - 29 July : Investigation of KiVi, KSBasE and KLighD projects(with special emphasis on KLighD)
- 30 July - 12 August :
- Performimg the integartion of KLighD into the editors of eTrice.
- 13 August - 19 August : Final Review of the Code and documentation for final submission.
For running the delivered plug-in (to perform layout in eTrice Diagrams), following KIELER plugins are required :
The plugins can be fetched from the KIELER git repository. (link below).
Moreover, some google libraries are also required. They are:
- com.google.guava (9.0.0)
It could be fetched from here.
(For mentors) The delivered plug-in could be reviewed on the Gerrit Code review system.
