PARC: Recommending API methods parameters

APIs have grown considerably in size. To free developers from remembering every detail of an API, code completion has become an integral part of modern IDEs. Most work on code completion targets completing API method calls and leaves the task of completing method parameters to the developers. However, parameter completion is also a non-trivial task. We present an Eclipse plugin, called PARC, that supports automatic completion of API method parameters. The tool is based on the localness property of source code, which states that developers tend to put related code fragments close together. PARC combines contextual and static type analysis to support a wide range of parameter expression types.
