VariantSync

VariantSync is a research project funded by DFG and an open-source tool. The goal of both is to bridge the gap between clone-and-own and software product lines.

Want to find out what is meant with clone-and-own and why it is problematic? Curious how it can be supported with version control systems and build systems?

@VariantSync @SchultheissAlex This is not science fiction. The bridge exists in reality.

Clone-and-own is in Bavaria (Neu-Ulm) and product lines are in Baden-Württemberg (Ulm).

[VariantSync @VariantSync]

Clone-and-own is like a forest fire.

You need to work against the fire (maintenance) or migrate to a product line. Feature traces can help to bridge the gap.

Feature trace recording is the first step towards our vision for bridging the gap between clone-and-own and software product lines in our project @VariantSync. You may read about it in our #ICSE NIER paper (https://t.co/4RTSNXABWa) or watch it (https://t.co/no7JBlbcof) 😊. 8/8

In March 2020, Paul Bittner started on a PhD position in the VariantSync project. His master's thesis on the Semi-Automated Inference of Feature Traceability During Software Development is available online: https://t.co/1nSvlLm4FK

When 2 co-authors sent back revisions of the same manuscript simultaneously, and you use "a tool to easily & automatically merge" the 2 versions.

Happy to announce that the German Research Foundation @dfg_public accepted the grant proposal by Timo Kehrer and me. With @VariantSync, we aim to automate the synchronization of software variants. The grant incorporates a total of 618,000 € for 2 PhD students over 3 years.
