WhyLine swMATH ID: 38508 Software Authors: Ko, Amy J.; Myers, Brad A. Description: Designing the whyline: a debugging interface for asking questions about program behavior. Debugging is still among the most common and costly of programming activities. One reason is that current debugging tools do not directly support the inquisitive nature of the activity. Interrogative Debugging is a new debugging paradigm in which programmers can ask why did and even why didn’t questions directly about their program’s runtime failures. The Whyline is a prototype Interrogative Debugging interface for the Alice programming environment that visualizes answers in terms of runtime events directly relevant to a programmer’s question. Comparisons of identical debugging scenarios from user tests with and without the Whyline showed that the Whyline reduced debugging time by nearly a factor of 8, and helped programmers complete 40 Homepage: https://dl.acm.org/doi/abs/10.1145/985692.985712 Related Software: CompoSAT; Alloy; VERMEER; Whispec; Bordeaux; MiniSat; Kodkod; cddiff; CD2Alloy; margrave; Alloy*; Korat; TestEra; Mace4; z3; CUTE; Jython; BYTESURGEON; Squeak; AspectS Cited in: 2 Documents all top 5 Cited by 6 Authors 1 Denker, Marcus 1 Ducasse, Stéphane 1 Krishnamurthi, Shriram 1 Nelson, Tim 1 Porncharoenwase, Sorawee 1 Tanter, Éric Cited in 1 Serial 1 Computer Languages, Systems & Structures Cited in 1 Field 2 Computer science (68-XX) Citations by Year
