Module Ocaml_version.HasSource

Test whether a release has a given feature.

Sourceval bytes : t -> bool

bytes t will return true if that release has a bytes type. Note that opam provides a bytes compatibility package for older releases.

Sourceval arch : arch -> t -> bool

arch a t will return true if architecture a is supported on release t.

Sourceval options_packages : t -> bool

options_packages t will return true if the release t uses ocaml-option-* packages in opam-repository, rather than +variant packages

Sourceval multicore : t -> bool

multicore t will return true if the release t has a multicore OCaml fork available for it. This requires the https://github.com/ocaml-multicore/multicore-opam opam switch to be added before the package is available.

Note that the multicore variants changed between 4.10 and 4.12, and this function returns true for any of them.
