EMF Compare/Textual diff in model diff
When settings of EAttributes are different, the EMF compare tree editor only diplays a "modified" difference. This is somewhat insufficient when comparing an EAttribute being used for storing documentation, comments or even source code. In such a case, we would like to provide the ability to open a textual diff editor in a popup windows (as JUnit failure opens when comparing different expected and computed results).
We propose to open such an editor by double-clicking on a EAttribute diff setting in the tree editor. The kind of EAttribute pertinent for this use has the following properties:
- eType.instanceClassName : java.lang.String
- changeable: true
- derived : false
- transient : false
