  33. Content • Requirements • Xtext over IMP • Importing Grammar • Feature Classification • Features • Challenges • Future work Eclipse IDE GIT Plug-In UI Workbench Doxygen Plug-In SVN Plug-In Xtext Plug-In

  34. Requirements • Editor that recognizes the Control language • Provides the user with 28 features • User friendly programming environment Requirements Xtext Grammar Features Challenges Future Work

  35. Why Xtext • Better documentation • Features derived from Eclipse • Officially supported tool Requirements Xtext Grammar Features Challenges Future Work

  36. Importing grammar • Use of lex and yacc files  BNF • Transformations ( avoid left recursions ) • Restructuring grammar elements helps feature developers • Cross reference reduces the development time Requirements Xtext Grammar Features Challenges Future Work

  37. Feature Classification Requirements Xtext Grammar Features Challenges Future Work

  38. Auto-complete Function Names Requirements Xtext Grammar Features Challenges Future Work

  39. Rules Based Code Reformatting Requirements Xtext Grammar Features Challenges Future Work

  40. Multiple Variable Definition Requirements Xtext Grammar Features Challenges Future Work

  41. Package Import Requirements Xtext Grammar Features Challenges Future Work

  42. Validation Rules Requirements Xtext Grammar Features Challenges Future Work

  43. Challenges • Many features are grammar related • Conflicts between grammar and feature implementation. • Grammar semantics are useful but take time. • Grammar needed some kind of restructuring. • No support for some non-derived features • Some features developed from scratch. • Only few plugins available. Requirements Xtext Grammar Features Challenges Future Work

  44. Future work • Grammar, Grammar, Grammar! • Semantics instead of validations • Restructuring (optimization) • Optimizing the implementation of some features to achieve better total performance. Requirements Xtext Grammar Features Challenges Future Work

  45. Content Eclipse IDE • Requirements • Expectation • Design decisions • Reality • Modern Debugger • Features • Ctrl Debugger • Challenges • Future work UI Workbench WinCC-OA System Debugger Plug-In
