PROFILE
Jelle De Coninck
Worked on the Guardsquare/proguard-core repository to enhance source mapping and debugging capabilities for Java and Kotlin code. Over three months, delivered features that improved line number tracking, including the introduction of StructuredLineNumberInfo for granular line-origin data and a NO_LINE origin to handle missing information. Refactored core components like CodeAttributeEditor to support restoration and accurate fallback of line numbers after code transformations. Focused on API design, classfile manipulation, and robust code refactoring, these changes increased mapping accuracy, improved editor reliability, and streamlined developer workflows, addressing edge cases in code navigation and supporting more reliable analysis of transformed code.

Oct 1, 2025Month: 2025-10 — Monthly summary for Guardsquare/proguard-core focused on enhancing line-origin handling to improve code navigation reliability and editor robustness. Key feature delivered this month: Line Origin Enhancement and Robust Line Tracking, introducing a NO_LINE origin to the LineOrigin enum and updating CodeAttributeEditor to use this origin for fallback/restored lines. This change strengthens line-number accuracy when previous line information is unavailable, delivering tangible business value by improving developer productivity and reducing confusion in code inspection workflows.
