Automated API migration in a user-extensible refactoring tool for Erlang programs

Wrangler is a refactoring and code inspection tool for Erlang programs. Apart from providing a set of built-in refactorings and code inspection functionalities, Wrangler allows users to define refactorings, code inspections, and general program transformations for themselves to suit their particular needs. These are defined using a template- and rule-based program transformation and analysis framework built into Wrangler. This paper reports an extension to Wrangler´s extension framework, supporting the automatic generation of API migration refactorings from a user-defined adapter module.
