EMF DiffMerge/Default GUI
Overview
In addition to a diff/merge engine, EMF Diff/Merge provides simple GUI components for visualizing comparisons and letting end-users merge models manually.
A default mechanism provides a comparison action (pop-up menu) which allows end-users to open a comparison in an editor. This mechanism can be customized to support different kinds of comparison. Alternatively, a comparison can be displayed in other graphical contexts.
Default comparison action
The default comparison action is applicable on workspace files. Select 2 or 3 model files in the Eclipse workspace, right-click, then select Compare with, Each Other as models. Note that the corresponding metamodel(s) must be registered in the platform.
When started, the diff/merge tool displays a progress dialog. Computing the differences between models takes time according to the size of the models and the number of differences between them. Click the Run in background button in order to keep working with Eclipse while the differences are being computed in parallel.
