Tutorial – Refactoring and Analysis with RefactorErl

« back to Presentations Download Presentation Download

RefactorErl is a source code analyser and transformer tool aimed at refactoring Erlang software. The tool itself is written in Erlang with a  unique approach: semantic analysis results are stored in a Mnesia database to avoid repeated analysis of the same source code, and simple, syntax-based manipulations are available that hide the details of handling separators, comments, and code layout.

This 90 minute tutorial introduces the main features of RefactorErl: how you can use it simply as a refactoring tool, and how analysis results can help you during software development and maintenance.

    Melinda Tóth is a first year PhD student at the Eötvös Loránd University of Budapest, Hungary.  She has been working with Erlang since 2007 with the RefactorErl project. Melinda received her master's degree in Computer Science in 2009 from Eötvös Loránd University. Both her bachelor and master's theses were based on Erlang and function related refactorings. In 2008 she spent five months at University of Kent where she worked with Wrangler. Melinda teaches Functional Languages at the University: Haskell and Erlang. Her PhD research field is about data and control flow graphs for functional languages, and impact analysis of refactoring.
