Abstract

In this talk we describe our experience in using an automatic API-migration strategy dedicated at changing the signatures of OCaml functions, using the Rotor refactoring tool for OCaml. We perform a case study on open source Jane Street libraries by using Rotor to refactor comparison functions so that they return a more precise variant type rather than an integer. We discuss the difficulties of refactoring the Jane Street code base, which makes extensive use of ppx macros, and ongoing work implementing new refactorings.
