-- _Unparsing von Datenstrukturen zur Analyse von C-Präprozessor-Variabilität_, Eugen Shulimov, Bachelor's Thesis, 2025, [DOI 10.17619/UNIPB/1-2385](http://doi.org/10.17619/UNIPB/1-2385), (german): Eugen added an unparser for variation trees, essentially inverting the horizontal arrows in our commuting diagram at the top of this README file. The unparser for variation diffs reuses the unparser for variation trees by projecting a variation diff to its two variation trees (before and after the change), unparsing the trees, and then diffing the obtained text file to eventually compute a text-based diff.

 - _Constructing Variation Diffs Using Tree Diffing Algorithms_, Benjamin Moosherr, Bachelor's Thesis, 2023, [DOI 10.18725/OPARU-50108](https://dx.doi.org/10.18725/OPARU-50108): Benjamin added support for tree-differencing and integrated the GumTree differencer ([Github](https://github.com/GumTreeDiff/gumtree), [Paper](https://doi.org/10.1145/2642937.2642982)). In his thesis, Benjamin also reviewed a range of quality metrics for tree-diffs with focus on their applicability for rating variability-aware diffs. The [org.variantsync.diffdetective.experiments.thesis_bm](src/main/java/org/variantsync/diffdetective/experiments/thesis_bm) package implements the corresponding empirical study and may serve as an example on how to use the tree-differencing.
 - _Reverse Engineering Feature-Aware Commits From Software Product-Line Repositories_, Lukas Bormann, Bachelor's Thesis, 2023, [10.18725/OPARU-47892](https://dx.doi.org/10.18725/OPARU-47892): Lukas implemented an algorithm for feature-based commit-untangling, which turns variation diff into a series of smaller diffs, each of which contains an edit to a single feature or feature formula. This work was later refined in our publication _Views on Edits to Variational Software_ illustrated above.
 - _Inspecting the Evolution of Feature Annotations in Configurable Software_, Lukas Güthing, Master's Thesis, 2023: Lukas implemented different edge-types for associating variability annotations within variation diffs. He published his work later at VaMoS 2024 under the title _Explaining Edits to Variability Annotations in Evolving Software Product Lines_, illustrated above. His work can be found in a [fork][forklg] of DiffDetective.
