Does this skill support optional dependencies during migration?

Yes, it identifies conditional libraries in topkg and applies the (optional) stanza in the generated Dune files to maintain correct dependency behavior.

Is it safe to delete the old build files immediately?

The skill provides a verification checklist (dune build @check, etc.). Once verified, it guides you through removing legacy files like _tags and the pkg/ directory.

Can it help resolve build warnings in the new Dune configuration?

Yes, it specifically handles common migration warnings like unused variables by suggesting appropriate library flags such as -w -27.

Which legacy OCaml files are analyzed during the migration?

The skill analyzes _tags for compilation flags, pkg/pkg.ml for package descriptions, .mllib for library modules, and pkg/META for findlib metadata.

Herramientas para Desarrolladores

Automates the conversion of OCaml projects from legacy ocamlbuild and topkg build systems to the modern Dune build system.

This skill provides a structured workflow for modernizing OCaml projects by migrating them from ocamlbuild, topkg, or findlib-based systems to Dune. It systematically analyzes legacy artifacts such as _tags, .mllib, and pkg.ml files to generate appropriate dune-project and library stanzas, handles optional dependencies, configures test suites, and updates opam files. By automating the mapping of compilation flags and module structures, it ensures a reliable transition to current OCaml industry standards while cleaning up deprecated metadata.
