// Phase 2 step 2.7 (PLAN-FFI.md): xfail then green for the remaining // six type-introducer directive forms parsing with the same body // grammar as `#jni_class`. No codegen yet — Phase 3 picks up Obj-C // codegen, Phase 4 picks up Swift. // // The directives this step turns on: // #jni_interface — Java interface binding // #objc_class — Obj-C class binding // #objc_protocol — Obj-C protocol binding // #swift_class — Swift class binding (via @_cdecl bridge) // #swift_struct — Swift @frozen value-type binding // #swift_protocol — Swift @objc-bridgeable protocol binding // // Internally the AST collapses into one `foreign_class_decl` node // carrying a `runtime` discriminator. Today the parser rejects each // of these because the lexer doesn't recognise the directive name. #import "modules/std.sx"; IFoo :: #foreign #jni_interface("com/example/IFoo") { bar :: (self: *Self) -> s32; } NSString :: #foreign #objc_class("NSString") { length :: (self: *Self) -> s32; } NSCopying :: #foreign #objc_protocol("NSCopying") { copy :: (self: *Self) -> *Self; } URL :: #foreign #swift_class("Foundation.URL") { absoluteString :: (self: *Self) -> *void; } Date :: #foreign #swift_struct("Foundation.Date") { timeIntervalSince1970 :: (self: *Self) -> f64; } Hashable :: #foreign #swift_protocol("Swift.Hashable") { hash :: (self: *Self) -> s32; } main :: () -> s32 { print("parse-only ok\n"); 0; }
