Ilie Savga, Florian Heidenreich. Refactoring in Feature-Oriented Programming: Open Issues.

Similar to refactoring, feature-oriented programming can be seen as a metaprogramming paradigm, in which programs are values and composition operators transform programs to programs. In this position paper we discuss open issues of applying refactoring in the context of feature-oriented programming. First, we elaborate on the role of refactoring in maintaining features and their implementations as well as the impact of refactoring on the relation between the prob- lem and solution spaces. Second, we discuss issues of relating well-known refactoring formalisms to existing formal approaches used in feature-oriented programming. Third, we suggest to use refactoring semantics to upgrade and test final products of a product line.
