Context-Selection for Git Diff: Budgeted Submodular Maximization on Typed Code Dependency Graphs

Puntos clave

To formalize the process of context selection for Git diffs using budgeted submodular maximization on code property graphs.
Developed a theoretical foundation for context selection algorithm.
Utilized budgeted submodular maximization with multi-resolution fragments.
Applied Personalized PageRank for relevance propagation in code dependencies.
Presented a framework for context selection in code diffs.
Empirical evaluation to be conducted in future work.

Resumen

Formalizing diff context selection as budgeted submodular maximization over typed Code Property Graphs with multi-resolution fragments and information-need-driven utility, where relevance propagates via weighted structural dependencies from edited code using Personalized PageRank. This paper presents the theoretical foundation for the TreeMapper project's context selection algorithm. Empirical evaluation is the subject of forthcoming work. Community testing and bug reports welcome.
