Is the UI useable on RCP app without (too many) dependancies ? [message #1276954]

Hi,

I'm currently working on adding merge feature on an RCP application. In that context I'm starting to use you (good) diff/merge engine and I've read most information published on the wiki.

However, I've not found real examples of how to use the minimum UI components, and I wonder if using it would leads me to also include (too many) dependancies. I tried EMF Compare and this ruins my RCP apps as a lot of eclipse things came with it (team, Git...).

So do you have a small, working example of how to use it and some informations regarding dependancies (FYI, my app is based on EMF and GEF, not GMF).

Regards

Hello Jean-Baptiste,

The basic EMF Diff/Merge feature is indeed tailored for the Modeling platform and includes a customization for GMF.

Nevertheless, you may just include in your RCP application plug-ins org.eclipse.emf.diffmerge (engine) and org.eclipse.emf.diffmerge.ui (GUI).

Here are the transitive dependencies.

* Engine:
org.eclipse.core.runtime
org.eclipse.osgi
org.eclipse.equinox.common
org.eclipse.core.jobs
org.eclipse.core.runtime.compatibility.registry
org.eclipse.equinox.registry
org.eclipse.equinox.preferences
org.eclipse.core.contenttype
org.eclipse.equinox.app
org.eclipse.emf.ecore
org.eclipse.emf.common
org.eclipse.emf.ecore.xmi
org.eclipse.emf.edit
org.eclipse.emf.ecore.change

* GUI: same as engine plus:
org.eclipse.compare
org.eclipse.compare.core
org.eclipse.ui
org.eclipse.swt
org.eclipse.jface
org.eclipse.core.commands
org.eclipse.ui.workbench
org.eclipse.emf.ecore.edit
org.eclipse.emf.edit.ui
org.eclipse.ui.views
org.eclipse.emf.common.ui
org.eclipse.emf.workspace
org.eclipse.core.resources
org.eclipse.emf.transaction
org.eclipse.emf.validation

Is that OK for your needs?

Cheers,
Olivier

Hi,

Thank you for your answer.

This list of dependancies seems fine and manageable.

Do you have a code snippet or example of how to use the UI? I've tried to figure how to do it through the wiki but didn't succeed so far.

Regards

Hi Jean-Baptiste,

I just added a simple dialog for displaying comparisons and merging without using the Eclipse Compare mechanism. It is called ui.util.DiffMergeDialog and it is included in the last build (see "Build jobs: main" in the wiki page).

final EMFDiffNode diffNode = new EMFDiffNode(YOUR_COMPARISON, ...);
final Display display = Display.getDefault();
display.syncExec(new Runnable() {
  public void run() {
    DiffMergeDialog dialog = new DiffMergeDialog(
        display.getActiveShell(), "Your Title", diffNode);
    dialog.open();
  }
});
