Proceedings of the 19th Workshop on Logic-based methods in Programming Environments (WLPE 2009) (1002.4535v1)

Abstract: This volume contains the papers presented at the 19th Workshop on Logic- based methods in Programming Environments (WLPE'09), which was held in Pasadena, USA, on July 14th, 2009. WLPE aims at providing an informal meeting for researchers working on logic-based methods and tools which support program development and analy- sis. This year, we have continued and consolidated the shift in focus from en- vironmental tools for logic programming to logic-based environmental tools for programming in general, so that this workshop can be possibly interesting for a wider scientific community. All the papers submitted to WLPE'09 have gone through a careful process of peer reviewing, with at least three reviews for each paper and a subsequent in-depth discussion in the Program Committee.
