Binaryen.ml
OCaml bindings for Binaryen.
Binaryen is a compiler and toolchain infrastructure for WebAssembly. It makes compilation to WebAssembly pretty darn easy.
Here's Binaryen's hello world test in OCaml form:
open Binaryen
let wasm_mod = Module.create ()
(* Create function type for i32 (i32, i32) *)
let params = Type.create [| Type.int32; Type.int32 |]
let results = Type.int32
(* Get arguments 0 and 1, add them *)
let x = Expression.local_get wasm_mod 0 Type.int32
let y = Expression.local_get wasm_mod 1 Type.int32
let add = Expression.binary wasm_mod Op.add_int32 x y
(* Create the add function *)
(* Note: no additional local variables *)
let adder = Function.add_function wasm_mod "adder" params results [||] add
let _ = Module.print wasm_mod
let _ = Module.dispose wasm_mod
Feature Parity
This project aims to provide full feature parity with the Binaryen C API. It's fairly complete, but a few things still need bindings:
SIMD instructions
Events
Atomics
Query operations on expressions
Query operations on functions
None of these are particularly challenging to create bindings for—they just haven't been written yet. If you need anything that's missing, feel free to open a PR.
Contributing
After cloning the repository, be sure to initialize the Binaryen submodule:
git submodule update --init
You'll need Node.js and esy
to build this project, as well as cmake
to build Binaryen.
dune
will take care of building Binaryen and compiling the C stubs, so to build the project you'll only need to run:
esy
This will take a while. Once it's done, you can run the tests:
esy test
