Tool Support for Refactoring Functional Programs We demonstrate the Haskell Refactorer, HaRe, and the Erlang Refactorer, Wrangler, as examples of fully-functional refactoring tools for functional programming languages. HaRe and Wrangler are designed to handle multi-module projects in complete languages: Haskell 98 and Erlang/OTP. They are embedded in emacs (and gvim) and respect programmer layout styles. In discussing the construction of HaRe and Wrangler, we comment on the different challenges presented by Haskell and Erlang due to their differences in syntax, semantics and pragmatics. In particular, we examine the sorts of analysis that underlie our systems. Finally, drawing on our experience, we examine features common to functional refactorings, and contrast these with refactoring in the object-oriented domain.
