(I am reposting this with updated links) The RMoD team at INRIA Lille / France is offering a postdoc position: "Designing a pure trait-based language". Applications must be submitted online, the deadline is *March 14th*. More information and online application: http://bit.ly/cGkzn9 More on Postocs at INRIA: http://www.inria.fr/travailler/opportunites/postdoc/postdoc.en.html ====================================================================== Designing a pure trait-based language ===================================== Position type: Post-doctoral Fellow Functional area: Lille (Villeneuve d'Asq) Project: RMOD Environnement ============= Recently, traits have been proposed as a single inheritance backward compatible solution in which the composing entity has the control over the trait composition. Traits are fine-grained units used to compose classes, while avoiding many problems of inheritance and mixin-based approaches. To evaluate the expressiveness of traits, some hierarchies were refactored, showing code reuse. However, such large refactorings, while valuable, may not be facing all the problems, since the hierarchies were previously expressed within single inheritance and following certain patterns. In addition traits have always been considered in addition to class inheritance but not as the main composition and reuse mechanism. Missions ======= We are in the process of designing a pure traits based language. We want to evaluate the impact of having only traits as building blocks and removing inheritance from an object-oriented language. We expect the candidate to take part of the design of a pure traits-based programming language, to perform analysis on large pieces of software for remodularisation purposes and redesign a library. We expect the candidate to implement the core of a pure trait-based language and some representative examples. Compétences et Profil ==================== - have good skills in interpretation of object-oriented programming languages (classbased, prototypes, mixins...) - have an expertise in object-oriented programming languages outside Java, C++ and C# - be fluent in English Informations complémentaires ============================= Chercheur(s) à contacter pour plus dâinformation/advisors : Stéphane Ducasse : stephane.ducasse@inria.fr Marcus Denker : marcus.denker@inria.fr Bibliographical References: =========================== [1] Alexandre Bergel, Stéphane Ducasse, Oscar Nierstrasz and Roel Wuyts, Stateful Traits and their Formalization, Journal of Computer Languages, Systems and Structures, 2008.
