  Article:   UTILISING THE SOFTWARE METRICS OF REFACTORERL TO IDENTIFY CODE CLONES IN ERLANG.

  Abstract:   Code clones, the results of "copy& paste programming", are special types of bad smells. They have a negative impact on software development and maintenance lifecycle. The usual way to detect bad smells is to calculate software metrics. RefactorErl is a source code analysis and transformation tool for Erlang; it provides several software metrics to measure the complexity of the source code, and finds structures that violate some existing requirements or standards, or points out bad smells based on the results of them. In this paper we introduce an efficient, parallel,software metric based clone detection algorithm, which utilises software metrics of RefactorErl in an unusual way, for the functional programming language Erlang. We have successfully evaluated it on various open-source projects.
