Each editor supports
Highlighting is performed interactively. Subsequent validations are currently performed when the file is saved, with semantic validation occuring only for syntactically valid files. Incremental validation may be added in a future release.
Lexical, syntactic and semantic errors are indicated by standard problem markers so that the errors are underlined and navigable from the Problems View or from the editor overview side bars.
Successful meta-model validation requires that the meta-models can be located. This may be achieved by binding the meta-model names to the appropriate models using the Model Registry Property Page. This is accessible from Properties in the right button menu of the Navigator or Project Explorer Views.
The QVTr editor is normally associated with files *.qvtr and *.qvtrelation extensions. This may be changed using Window->Preferences|General->Editors->File Associations.
The QVTr editor and parser when invoked on a *.qvtr concrete syntax file, generates a *.qvtr.qvtrelation abstract syntax model. This file may be viewed using the QVT Relation Model editor.
The QVTr editor and unparser when invoked on a *.qvtrelation abstract syntax model, generates a *.qvtrelation.qvtr concrete syntax file.
The QVTc editor and parser are normally associated with *.qvtc for the concrete syntax, *.qvtcore for the EMOF-based abstract syntax and *.eqvtcore for the Ecore-based abstract syntax.
