Design Decisions• Current Debugger over New Debugger
– Consistency– Limitations
• Eclipse over NetBeans– Architecturally Similar– Lower Learning Curve– Third-party Plugin Support– DSL Support (Xtext, IMP)

Quality Attributes• Usability
– Learning System Features (Learning Curve)– Efficient System Usage– System Customization (Perspectives and Views)
• Portability– OS Compatibility

Requirements FeaturesGrammarXtext Challenges Future Work
Challenges• Many features are grammar related
– Grammar and feature interdependence• Grammar semantics are imported indirectly
• Grammar elements needed restructuring
• No support for some non-derived features– Few features developed from scratch
• Only few plugins available.Requirements FeaturesGrammarXtext Challenges Future Work
Future work• Grammar, Grammar, Grammar!
– Elegant way of implementing semantics– Restructuring (optimization)
• Optimizing the implementation of some features to achieve better total performance.
