Clone Detection and Elimination for Haskell
Christopher Brown and Simon Thompson
In John Gallagher and Janis Voigtlander, editors, PEPM'10: Proceedings of the 2010 ACM SIGPLAN Workshop on Partial Evaluation and Program Manipulation, pages 182-196. ACM Press, January 2010.Abstract
Duplicated code is a well known problem in software maintenance and refactoring. Code clones tend to increase program size and several studies have shown that duplicated code makes maintenance and code understanding more complex and time consuming.
This paper presents a new technique for the detection and removal of duplicated Haskell code. The system is implemented within the refactoring framework of the Haskell Refactorer (HaRe), and uses an Abstract Syntax Tree (AST) based approach. Detection of duplicate code is automatic, while elimination is semi-automatic, with the user managing the clone removal. After presenting the system, an example is given to show how it works in practice.
