Comb

User guide

0. Install Eclipse IDE for Java and DSL Developers, and install the Sirius 6.5 plug-in from the Eclipse Marketplace.
1. Clone or download the project.
2. Import the projects into your Eclipse IDE.
3. Start a new run-time Eclipse with the aforementioned projects: right click on a plug-in project (e.g. comb.expression.design) -> Run As -> Eclipse Application.
4. Import the comb.expression.design and the comb.examples projects into your run-time Eclipse.
5. Open the Modeling Perspective: Eclipse -> Window -> Perspective -> Open Perspective -> Other -> Modeling
6. In the Model Explorer view extend the Comb element within the My.comb file of the comb.examples project. Here you can see the root elements of the contained expressions and a graphical Sirius editor new CombDiagramDescription. To open it, double click it.
7. Here you can edit and save your requirements. You can observe various properties of the selected element in the Properties view.
8. The various functions of a comb requirement can be accessed by right clicking on an element under the main Comb element in the Model Explorer view and select "Comb generator".
9. Graphical trace representations are generated in dot format into the comb.examples project. These can be used by Graphviz (see "Further dependencies" section).

Further dependencies

The generated .dot format files can be viewed online, using Graphviz online

For in-Eclipse graphical trace representation, the following dependencies are needed:

1. Graphviz needs to be installed, where the dot executable path
   a. needs to be in the environment paths, or
   b. it can be specified manually in the Eclipse -> Window -> Preferences -> Graphviz menu.
2. The TextUML Toolkit 2.13.0 Eclipse plug-in needs to be installed (may not work on operating systems other than Windows). Its view can be accessed trough the Image Viewer view (Eclipse -> Window -> Perspective -> Open Perspective -> Other -> Image Viewer)

The contents of the Comb project

• comb.examples: contains the example files of the Comb project
• comb.expression.design: contains the graphical and textual representation of the operators. Also includes the configuration file (placed here, so its easier to access from the run-time eclipse)
• comb.expression.metamodel: contains the metamodel and the generated code which describe the supported operators
• comb.expression.metamodel.edit and comb.expression.metamodel.editor: projects generated from the comb.expression.metamodel project, will be used as Eclipse plugins which contain the implementation of the model editor
• comb.external.LTL2Buchi: contains the external LTL2Bchi project used for generating Büchi-automatons from LTL requirements
• comb.external.BatMonGen: contains the external BatMon Gen project used for generating monitor components from Büchi-automatons
• comb.external.jSSTL: contains the external jSSTL project used for generating monitor components from MTL, MITL, STL and SSTL based requirements
• comb.generator.action: contains the files which are implementing the functions of the context menu (like import, export, saving different automaton formats and interpretations, initiating monitor synthesis)
