Call for Papers Script to Program Evolution (STOP) at ECOOP 2009 July 6th, 2009, Genova, Italy Recent years have seen increased use of scripting languages in large applications. Scripting languages optimize development time, especially early in the software life cycle, over safety and robustness. As the understanding of the system reaches a critical point and requirements stabilize, scripting languages become less appealing. Compromises made to optimize development time make it harder to reason about program correctness, harder to do semantic-preserving refactorings, and harder to optimize execution speed. Lack of type information makes code harder to navigate and to use correctly. In the worst cases, this situation leads to a costly and potentially error-prone rewrite of a program in a compiled language, losing the flexibility of scripting languages for future extension. Recently, pluggable type systems and annotation systems have been proposed. Such systems add compile-time checkable annotations without changing a program's run-time semantics which facilitates early error checking and program analysis. It is believed that untyped scripts can be retrofitted to work with such systems. Furthermore, integration of typed and untyped code, for example, through use of gradual typing, allows scripts to evolve into safer programs more suitable for program analysis and compile-time optimisations. With very few exceptions, practical reports are yet to be found. The STOP workshop focuses on the evolution of scripts, largely untyped code, into safer programs, with more rigid structure and more constrained behaviour through the use of gradual/hybrid/ pluggable typing, optional contract checking, extensible languages, refactoring tools, and the like. The goal is to further the understanding and use of such systems in practise, and connect practise and theory. To this end, we encourage not only submissions presenting original research results, but also papers that attempt to establish links between different approaches and/or papers that include survey material, experience reports and tool demonstrations. Original research results should be clearly described, and their usefulness to practitioners outlined. Paper selection will be based on the quality of the submitted material, including surveys. Demos will judged on the perceived relevance for the intended audience. The accepted papers will be made available through ACM's digital library.
