Low coupling between modules and high cohesion inside each module are the key features of good software architecture. Systems written in modern programming languages generally start with some reasonably well-designed module structure; however with continuous feature additions, modifications and bug fixes, software modularity gradually deteriorates; and there is a need for incrementally improving modularity to avoid the situation when the structure of the system becomes too complex to maintain.
We demonstrate how Wrangler, a general-purpose refactoring tool for Erlang, could be used to maintain and improve the modularity of programs written in Erlang without dramatically changing the existing module structure. We identify a set of "modularity smells" and show how they can be detected by Wrangler and removed by way of a variety of refactorings implemented in Wrangler. Validation of the approach and usefulness of the tool are demonstrated by case studies.
