I´m not sure if this is the right place to ask this, but I couldn´t find any better place.
In my application I should compare two source code files to see if something has changed and then highlight those changes. For that i thought of using EMF compare. My application is a standalone application and is not used as a plugin or something similar. It should run without eclipse. Therefore I linked all the necessary libraries and tried to use EMF compare.
The problem now is that I don´t know how to build the two models that I have to use to compare the two source code files against each other. In the following code snippet I wrote as a first approach, the source code files are passed as files (Test1.java and Test2.java) but actually the source code of both files are stored in a string as the method parameters indicate.
So my question is basically how can I generate two models based on String that contain Java source code so that I can use these two models to compare against each other?
public void compare(String source1, String source2) throws IOException, InterruptedException {
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("java", new ResourceFactoryImpl());
XSDEcoreBuilder builder = new XSDEcoreBuilder();
Collection<EObject> model1 = builder.generate(URI.createFileURI("Test1.java"));
Collection<EObject> model2 = builder.generate(URI.createFileURI("Test2.java"));
final MatchModel match = MatchService.doMatch(model1.iterator().next(), model2.iterator().next(), Collections.<String, Object> emptyMap());
final DiffModel diff = DiffService.doDiff(match, false);
final List<DiffElement> differences = new ArrayList<DiffElement>(diff.getOwnedElements());
System.out.println("MatchModel :\n");
System.out.println(ModelUtils.serialize(match));
System.out.println("DiffModel :\n");
System.out.println(ModelUtils.serialize(diff));
}
