Matthew
During December 2025, this developer focused on enhancing the reliability of LimeSurvey’s core expression evaluation by addressing a critical bug in the Expression Manager’s JavaScript substr function. Their work involved correcting the handling of substring operations when the start parameter was zero, ensuring that string manipulations within dynamic surveys and form calculations produced accurate results. By concentrating on debugging and applying strong JavaScript skills, they improved the predictability and stability of string operations for end users. The contribution, delivered directly to the LimeSurvey/LimeSurvey repository, demonstrated careful attention to edge-case correctness and reinforced the robustness of the platform’s core logic.
