🌐 Phase 9.7: Box FFI/ABI + ExternCall Demo
✅ ExternCall Implementation Complete!
Universal Library Integration via WASM Runtime Imports
🎯 Architecture Overview
// Nyash External Call Pattern
console.log("Hello from Nyash!")
canvas.fillRect("demo-canvas", 50, 50, 100, 100, "red")
// Generated MIR ExternCall Instructions:
ExternCall {
dst: None,
iface_name: "env.console",
method_name: "log",
args: [string_ptr, string_len],
effects: IO
}
// Generated WASM Imports:
(import "env" "console_log" (func $console_log (param i32 i32)))
(import "env" "canvas_fillRect" (func $canvas_fillRect (param i32 i32 i32 i32 i32 i32 i32 i32)))
🎮 Interactive Demo
📊 Console Output:
🔧 Implementation Status
✅ Core Components Complete:
• MIR ExternCall instruction with effect tracking
• WASM RuntimeImports with console/canvas operations
• JavaScript import object generation
• BID specification compliance (console.yaml, canvas.yaml)
• String handling via (ptr, len) parameters
🚀 Ready for Universal Exchange:
External libraries can now be integrated via Box FFI/ABI!
