VariantSync Demo

This is an example for VariantSync. The following instructions are a guide for this example. For a step by step guide please consider the available screencasts.

0. Import all projects into your Eclipse Workspace. All Notepad projects should be marked as VariantSync projects () except for NotepadH. You might want to switch to the VariantSync perspective to open all necessary windows for the following examples.
1. Run variants A to D. You will see different implementations of notebooks, which are already developed with VariantSync.
2. Open the feature model in the variantsyncFeatureInfo project.
3. Create a new configuration NotepadH with the features FormatRaw and Undo in variantsyncFeatureInfo/configs.
4. Right click project NotepadH and click Configure > Add As Variant to enable VariantSync support for this project.
5. First example:
   • Set the context to TextStyled and start recording.
   • Open the Notepad.java in variant B.
   • After line 252, add a new line with the following content: textPane.setText("Hello VariantSync users");. When saving the file you will see the line annotated with feature TextStyled. As variant B is the only feature implementing this feature (visible in the Configuration Map) no synchronization has to be performed.
   • Stop recording.
6. Second example:
   • Set the context to Toolbar and start recording.
   • Open the Notepad.java in variant C.
   • In line 331, change the string North to South.
   • Compare variants C and E with the Eclipse compare view.
   • Open the Notepad.java in variant E.
   • Synchronize the variants with the source-focused view.
   • Look at the corresponding line of the Notepad.java in variant E
7. Third example:
   • Set the context to Undo and start recording.
   • Open the UndoAction.java in variant E.
   • Change the super call in the constructor from Undo to Undo Edit.
   • Synchronize the variants with the source-focused view.
   • Look at the results in variants A,C, and F (As NotepadH does not have feature MenuBar the change is not visible in the application). You can see all configurations implementing a feature in the configuration map of FeatureIDE.
8. Fourth example:
   • Set the context to Base and start recording.
   • Open the Notepad.java in any variant.
   • In the constructor, change the value 300 to 400.
   • Synchronize the variants with the source-focused view.
   • Look at the results in variants with and without merge conflicts.

Instructions for Resproductions of the Screencast

To reproduce the screencasts dedicated branches are available when a certain setup is required:

• Video 1 (Automating the Synchronization of Software Variants): You can use the master branch to reproduce this scenario.
• Video 2 (Setting-Up Legacy Clones for Synchronization): Please checkout the branch screencast_video2. At the end of the video you will see the project in a state like in the master branch.
• Video 3 (Recording Feature Mappings During Clone Evolution): You can use the master branch to reproduce this scenario.
• Video 4 (Change Synchronization into Multiple Clones): Please checkout the branch screencast_video4.
• Video 5 (Change Synchronization from Multiple Clones): Please checkout the branch screencast_video5. One of the changes may require a manual merge and cannot be merged automatically as shown in the video.
