WACS (C# WebAssembly Interpreter)

Overview

WACS is a pure C# WebAssembly Interpreter designed for .NET environments, including Unity's IL2CPP. It allows seamless execution of WASM modules with minimal setup, offering compatibility and advanced interop features.

Features

  • Pure C# Implementation: Built with C# 9.0/.NET Standard 2.1 (no unsafe code).
  • Unity Compatibility: Supports Unity 2021.3+ with IL2CPP/AOT compatibility.
  • Godot Compatibility: Compatible with Godot Engine - .NET.
  • Full WebAssembly MVP Compliance: Passes the WebAssembly spec test suite.
  • Interop Bindings: Host bindings created through reflection, requiring no boilerplate.
  • WASI Support: WACS.WASIp1 provides a wasi_snapshot_preview1 implementation.

Installation

Install WACS from NuGet:

dotnet add package WACS

Usage Example

Here's a basic example demonstrating how to load and run a WebAssembly module:

using System;
using System.IO;
using Wacs.Core;
using Wacs.Core.Runtime;

var runtime = new WasmRuntime();
runtime.BindHostFunction<Action<char>>(("env", "sayc"), c => Console.Write(c));

using var fileStream = new FileStream("HelloWorld.wasm", FileMode.Open);
var module = BinaryModuleParser.ParseWasm(fileStream);

var modInst = runtime.InstantiateModule(module);
runtime.RegisterModule("hello", modInst);

if (runtime.TryGetExportedFunction(("hello", "main"), out var mainAddr))
{
    var mainInvoker = runtime.CreateInvokerFunc<Value>(mainAddr);
    int result = mainInvoker();
    Console.Error.WriteLine($"hello.main() => {result}");
}
