OCaml2Go is a transpiler from OCaml bytecode to Golang. Although it can compile considerably complex OCaml code, project is in early stages of development, I would say proof of concept so far.
- resulting code is very slow (OCaml works with dynamic value representation, a
lot of
interface{}to get it working in Go) - large monolithic output takes long time to compile
- no OCaml or Go build system integration
OCaml2Go is build on top of Rehp, a fork of js_of_ocaml that supports pluggable backends.
Rehp produces intermediate representation, not specific to JavaScript backend, OCaml2Go takes it from there and produces Golang code.
OCaml2Go depends on some pending PRs to Rehp, so to build it you need to pin the following branch for now:
opam pin js_of_ocaml-compiler git+https://github.com/Lupus/rehp.git#ocaml2go
opam pin js_of_ocaml git+https://github.com/Lupus/rehp.git#ocaml2go
After that tests should be runnable with this script (from opam switch with all dependencies installed):
./testGo.sh
