Generative and component approaches have the potential to revolutionize so- waredevelopmentinasimilarwayasautomationandcomponentsrevolutionized manufacturing. Generative Programming (developing programs that synthesize other programs), Component Engineering (raising the level of modularization and analysis in application design), and Domain-Speci?c Languages (elevating program speci?cations to compact domain-speci?c notations that are easier to write and maintain) are key technologies for automating program development. GPCE arose as a joint conference, merging the prior conference on Gene- tive and Component-Based SoftwareEngineering (GCSE) and the Workshop on Semantics, Applications, and Implementation of Program Generation (SAIG). Thegoalof GPCEisto providea meeting placefor researchersandpractitioners interested in cutting edge approachesto software development. We aim to foster further cross-fertilization between the
