Hi,
EVL is an interpreted language and as such, no code needs to be
generated. Does this answer your question?
Cheers,
Dimitris

Hi,
For each marker type, you can contribute one or more extensions to the
org.eclipse.ui.ide.markerResolution extension point and define an
instance of IMarkerResolutionGenerator which contributes resolutions
(a.k.a quick fixes) for markers of this type. The resolution generator
for EVL constraints is EvlMarkerResolutionGenerator (in the
org.eclipse.epsilon.evl.emf.validation plugin).
Now, when you right-click on a marker and select "Quick Fix", the
Problems view finds all resolution generators that can provide
resolutions for the marker and collects the available resolutions by
invoking their getResolutions(IMarker marker) method (the
EvlMarkerResolutionGenerator class mentioned above generates instances
of EvlMarkerResolution which when invoked execute the respective "fix"
parts of the EVL constraints).
Finally, it populates the popup list with all the resolutions it has
collected and shows it to the user. I believe that this pop-up window is
reusable (i.e. part of the API) given that it can be invoked from other
parts of the UI as well (e.g. from in-editor markers). I hope this helps.
Cheers,
Dimitris

I've noticed that using evl together with GMF a class ValidationMarker is being generated.
This class contains information on a marker but is not tied with the IMarker class.
I'm trying to implement a quick fix feature for RCP apps, thus trying to get the quick fix popup starting from an instance of ValidationMarker, which I've managed to retrieve from my diagram and to show in my custom problem view, made up from scratch.
Now I'm stuck, since it seems anyway I need to work with instances of IMarker and not of ValidationMarker, for the EvlMarkerResolutionGenerator to return me instances of EvlMarkerResolution.
So, is there a way to do it? As far as I know in a RCP application it makes little sense to use IMarker, since there is no workspace, and so all the infrastructure needed by IMarker is missing.
Thank you
g

Hi,
I don't see any obvious workarounds at the moment. I'll have to have a
closer look at this and get back to you within the next couple of days.
Could you please send me the current version of your code so that I have
a good starting point?
Cheers,
Dimitris
