Hi,

Is it possible to set the OPTION_IGNORE_ID via an extension point or
something else?
I like to embed EMF Compare in my RCP application and use the compare UI.

Regards

Henrik

Hi Henrik,

I have never tried something like this, and know I haven't implemented
anything of the sort :).

You can try something like :
EMFCompareUIPlugin.getDefault().getPluginPreferences().setVa lue(EMFComparePreferenceKeys.PREFERENCE_KEY_IGNORE_ID,
true);

But I do not know if this can work since the "default" value for this
preference is set to false by EMF Compare.

Yes, I tried that. But it does not seem to work as you said. Is it
possible to create a extension point to set these default values?

No, providing an extension point to set _default_ values seems overkill.
What exactly is the need behind this? I could change the
GenericMatchEngine to allow preferences overriding if this could solve
the issue.

My users are signalling engineers, not programmers. When my RCP product
starts I want to set the OPTION_IGNORE_ID to true so that they can compare
our models files directly in the UI. I don't want them to first go into
Window->Preferences->EMF Compare and change a setting they don't
understand. They want to compare model files fast and easily.

Yes, that might be an good option.

henrik,

Could you raise a bugzilla entry for this preference issue? It will
require an API change and won't find its way into the 0.8 version. ATM,
a workaround would be to define your own match engine (extension point
org.eclipse.emf.compare.match.engine) for the file extensions you need
(or * with priority set higher than "lowest" if you need this for all
comparisons) and override the option map :

public class SpecificMatchEngine extends GenericMatchEngine {
public MatchModel resourceMatch(Resource leftResource, Resource
rightResource, Map<String, Object> optionMap) throws InterruptedException {
optionMap.put(EMFComparePreferenceKeys.PREFERENCE_KEY_IGNORE _ID, true);
super.resourceMatch(leftResource, rightResource, optionMap);
}

public MatchModel resourceMatch(Resource leftResource, Resource
rightResource, Resource ancestorResource, Map<String, Object> optionMap)
throws InterruptedException {
optionMap.put(EMFComparePreferenceKeys.PREFERENCE_KEY_IGNORE _ID, true);
super.resourceMatch(leftResource, rightResource, ancestorResource,
optionMap);
}
}
