history

Project history and usage

ocaml@4 packages the OCaml 4 compiler line separately from the main ocaml formula. It exists for projects and dependency graphs that still need the OCaml 4 runtime, compiler-libs AST, PPX compatibility, or build behavior rather than the OCaml 5 runtime model.

Project history

OCaml 4 began as the post-Objective Caml line that added features such as GADTs and first-class modules in 4.0. The 4.x series became the compatibility baseline for a large portion of the opam ecosystem across the 2010s and early 2020s, including packages whose PPX rewriters or compiler-libs dependencies track specific OCaml AST versions.

The 4.14 branch became the final OCaml 4 branch. OCaml.org release notes describe 4.14 as the last version of OCaml 4 and a long-term support branch for the transition to OCaml 5; OCaml 4.14.4 was released on 2026-06-15 with safe bug fixes and security fixes cherry-picked from OCaml 5.

Adoption history

The separate Homebrew formula reflects the same compatibility pressure seen in opam switches: developers may need a compiler line older than the default package to build older projects, reproduce releases, or support dependencies not yet migrated to OCaml 5.

How it is used

Users install ocaml@4 when a project specifies OCaml 4.14 or an older 4.x-compatible dependency set. The package exposes the standard OCaml compiler commands, including ocaml, ocamlc, ocamlopt, ocamldep, ocamldoc, ocamllex, ocamlyacc, ocamlobjinfo, and runtime utilities.

Why package nerds care

Versioned compiler formulae are important for OCaml because compiler releases affect ABI, compiler-libs APIs, PPX ASTs, and package solver outcomes. ocaml@4 is a compact example of a package manager preserving a language ecosystem's old compiler branch while the main formula follows OCaml 5.

Timeline

  • 2012: OCaml 4.0 added GADTs and first-class modules.
  • 2016: OCaml 4.03 split ocamlbuild into an independent project.
  • 2022: OCaml 5.0 introduced a rewritten runtime and began the transition away from OCaml 4 as the main line.
  • 2024-03-14: OCaml 4.14.2 release notes described 4.14 as the last OCaml 4 branch.
  • 2026-06-15: OCaml 4.14.4 was released with safe bug fixes and security fixes cherry-picked from OCaml 5.

Related projects

  • ocaml@4 pairs with opam switches, findlib, Dune, ocamlbuild, and PPX tooling in older projects. Its practical relationship to brew:ocaml is version selection rather than a separate language lineage.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for ocaml@4. Nucleus package metadata is still published here so future coverage has a stable package URL.

Install behavior

  • No Homebrew post-install hook is recorded in formula metadata.
  • Homebrew bottle metadata is available for 6 platform targets.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
