To use a framework, developers often need to hook into and customize some of its functionality. These customizations are often made by instantiating a type provided by the framework, or by extending or implementing a framework type and instantiating this subtype, and providing the resulting object to other framework objects. Recommending extension patterns that frequently occur at such extension points can help developers to adopt a new framework correctly and to exploit it fully. In this paper we transpose an existing technique for mining extension patterns in Java projects to the Scala context. Our goal is to evaluate whether the unique features of the Scala language have an impact on the mined extension patterns. To this aim, we propose SCALA-XP-MINER, a tool for mining extension point patterns in Scala projects. We preliminary evaluate SCALA-XP-MINER on a corpus of 9 projects using the SWING framework. Our first results reveal that extension points are not very diffused in Scala projects using SWING and that only one type of extension points is adopted by developers.
