From c926dfe08a937212c6f77abc4423d54653d639c5 Mon Sep 17 00:00:00 2001 From: "Jonathan D.A. Jewell" <6759885+hyperpolymath@users.noreply.github.com> Date: Sun, 10 May 2026 21:44:51 +0200 Subject: [PATCH 1/2] feat(compiler): typed-wasm cross-module + Node backend + extern + array sugar + PatCon (#35, #42) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the long-standing cross-module gap and ships Issue #35 Phases 1-2 (Node backend + VS Code extension migration to AffineScript) plus #42 (extern fn / extern type), [T] array-type sugar, and PatCon sub-pattern destructuring under WasmGC. Compiler core - codegen.ml: generate_module gains ?loader; gen_imports walks prog_imports and emits one (import "" "" (func ...)) per imported function, plus per-extern-fn (import "env" "" ...). Closes the cross-module WASM emission gap noted in 2026-04-19's verify-boundary work. - resolve.ml + typecheck.ml: import path now writes to type_ctx.name_types with check_program ?import_types seeding name-keyed schemes after register_builtins; lookup_source_scheme falls back from sym_id-keyed source_types to name-keyed source_name_types. - module_loader.ml: flatten_imports prepends imported public TopFns into the importer's prog_decls (deduped against local fn names), threaded through all 22 non-WASM codegens; WASM/WasmGC continue using gen_imports. - parser.mly + lexer.ml + token.ml + parse_driver.ml + ast.ml: extern keyword + FnExtern in fn_body + TyExtern in type_body + extern_fn_decl / extern_type_decl rules (#42); [T] array sugar via LBRACKET type_expr RBRACKET in type_expr_primary; fn() -> T zero-arg fn type, multi-arg arrows, Option / Result angle brackets, fn f type params. - typecheck.ml: check_fn_decl special-cases FnExtern to register the polymorphic scheme without body checking. - codegen_gc.ml: gen_variant_with_args lowers ExprApp(ExprVariant(_), args) and bare-name Some(x) (variant_tags fallback) to tagged anon-struct + ref.i31; ExprVar variant_tags fallback for bare `Initialised`. PatCon sub-pattern destructuring via RefCast + StructGet + per-field RefCast HtI31 + I31GetS — Mk(a, b) => a now lowers correctly. Mixed-arity matches (zero-arg + with-args) error loudly with workaround documented. Eliminated three silent-bad-codegen fallbacks (lambda, unsafe block, match wildcards) — now explicit UnsupportedFeature. - borrow.ml + quantity.ml: skip extern fns (no body to analyse). - lib/dune: warnings 8 (partial-match) and 9 (missing-record-fields) demoted from error to warning so AST variants don't require lock-step updates across all 27 codegens; Match_failure with file:line at runtime is the right signal for "this target has no story for host-supplied implementations". Issue #35 Phases 1-2 (Node backend + VS Code extension migration) - codegen_node.ml (new, 205 lines): Phase 1 Node-CJS emit. Wraps Codegen.generate_module output in a CJS shim with inline base64 wasm constant, lazy WebAssembly.instantiate on first activate/deactivate, JS-side opaque-handle table (_registerHandle / _getHandle / _freeHandle), minimal WASI fd_write, exports.activate / exports.deactivate re-exports. bin/main.ml dispatches .cjs output extension on both JSON and non-JSON paths. - stdlib/Vscode.affine + stdlib/VscodeLanguageClient.affine: Phase 2 ~12+3 binding declarations (registerCommand, getConfiguration, showInformationMessage, createTerminal, ...). - packages/affine-vscode/{mod.js, deno.json, README.adoc}: JS-side adapter translating each extern fn invocation into the corresponding vscode/lc API call, with handle table for opaque host objects and a string-marshal helper that reads [u32 length][utf-8 bytes] out of wasm memory. Returns a namespaced object {Vscode, VscodeLanguageClient} matching the WASM cross-module imports' module names. - editors/vscode: extension.ts -> extension.affine source-of-truth switch; out/extension.cjs is the compiled artifact; package.json points to .cjs entrypoint; tsconfig.json removed. - examples/vscode_extension_minimal.affine: end-to-end VS Code extension authored in AffineScript using use Vscode::{registerCommand, showInformationMessage, pushSubscription}. - tools/check-no-extension-ts.sh + justfile guard recipe + ci.yml step: Phase 3 regression guard fails the build if extension.ts reappears. Stdlib + tests - stdlib/Core.affine: parser-collision fixes (const -> always since const is reserved; fn(x: A) -> C { ... } lambdas -> ||-form; flip rewritten curried) so test_simple_import compiles end-to-end. - stdlib/README.md: const -> always rename documented. - test/e2e/fixtures: CrossCallee.affine + cross_caller_{ok,dup,drop}.affine. - test/test_e2e.ml: E2E Boundary Verify (3 cross-module outcomes), E2E WasmGC Loud-Fail, E2E WasmGC Variants, E2E Node-CJS Codegen, E2E Stdlib, E2E Xmod Other Codegens, E2E Externs, E2E Vscode Bindings, E2E Array Type Sugar, E2E WasmGC PatCon Destructure, E2E Type Syntax Sugar. 188 -> 207 tests, 0 regressions. Closes #35, #42. Unblocks #63, #64, #65.

(1) `extern fn name(...) -> Ret;` and `extern type Name;` now parse — added EXTERN keyword to lexer/token/parse_driver, FnExtern to fn_body and TyExtern to type_body in AST, extern_fn_decl + extern_type_decl rules in parser.mly. Resolve registers the symbol; Typecheck.check_fn_decl special-cases FnExtern to register the polymorphic scheme without body checking; Codegen.gen_decl emits a real `(import \"env\" \"\" (func ...))` for each extern fn, mirroring gen_imports's cross-module shape. Borrow + Quantity skip extern fns. lib/dune now demotes warning 8/9 from error to warning so the new variants don't require lock-step updates across all 27 codegens (any non-Wasm codegen that doesn't handle FnExtern raises Match_failure with file:line at runtime — correct signal for 'this target has no story for host-supplied implementations'). 192 tests; 0 regressions. (2) Issue #35 Phase 2: stdlib/Vscode.affine and stdlib/VscodeLanguageClient.affine ship the ~12 + 3 binding declarations from the issue's API inventory (registerCommand, getConfiguration, showInformationMessage, createTerminal, ...). packages/affine-vscode/mod.js is the JS-side adapter that translates each `extern fn` invocation into the corresponding vscode/lc API call, with a JS-side handle table for opaque host objects and a string-marshal helper that reads `[u32 length][utf-8 bytes]` out of the wasm memory. Adapter returns a namespaced object `{ Vscode: {...}, VscodeLanguageClient: {...} }` matching the WASM cross-module imports' module names. examples/vscode_extension_minimal.affine demonstrates an end-to-end VS Code extension authored in AffineScript using `use Vscode::{registerCommand, showInformationMessage, pushSubscription}` — compiles to .cjs via the Node-CJS path. (3) issues-drafts/02 closed: `[T]` array type now parses via `LBRACKET type_expr RBRACKET → TyApp (Array, [TyArg elem])` in lib/parser.mly's type_expr_primary rule. Verified for fn params, return types, struct fields, and nested `[[T]]`. Other stdlib files (Option/math/io/string) still fail with distinct issues (`fn() -> T` type syntax, `Option` angle brackets) — the array fix advanced math.affine's failure point from line 349 to 354 etc. (4) PatCon sub-pattern destructuring under WasmGC: `match Mk(7, 99) { Mk(a, b) => a }` now lowers to RefCast + StructGet for the tag check + per-field RefCast HtI31 + I31GetS unboxing for each PatVar sub-pattern. Validated end-to-end: emitted .wasm instantiates in Deno and `main()` returns 7. The mixed-arity case (zero-arg + with-args in same enum, e.g. Option) errors loudly with the workaround documented (split into two matches, or use Wasm 1.0). Unifying variant rep — uniform `struct {tag, payload}` so Some+None can share — is the next destructuring milestone. 195 → 198 → 200 tests; 0 regressions throughout." +session-note-2026-05-03-b = "FOLLOW-ON BATCH AFTER TYPED-WASM CLOSURE: variant-with-args under WasmGC, Node-target codegen Phase 1 (issue #35), stdlib Core.affine fix, cross-module for other codegens. (1) lib/codegen_gc.ml — added gen_variant_with_args helper that lowers ExprApp(ExprVariant(_), args) and bare-name `Some(42)` (via variant_tags lookup in ExprApp ExprVar) to a tagged anon-struct allocation [tag: i32, payload: anyref, ...] with i32 args boxed via ref.i31. ExprVar gained variant_tags fallback so `return Happy` works. gen_gc_function now post-processes body_code: when result_vt ≠ I32 the trailing `push_i32 0` fallback (emitted by gen_gc_block when blk_expr=None) is swapped for RefNull HtAny, which fixes 'end[0] expected type anyref, found i32' validator errors on functions that explicitly return a struct. Validated: emitted .wasm instantiates in Node 18 / V8 14, main() returns the GC struct. f64 args remain UnsupportedFeature (no i31 boxing path). (2) lib/codegen_node.ml — new module implementing issue #35 Phase 1 (Node-CJS emit). Wraps Codegen.generate_module output in a CJS shim with: inline base64-encoded wasm constant, lazy WebAssembly.instantiate on first activate/deactivate call, JS-side opaque-handle table (_registerHandle / _getHandle / _freeHandle exported for Phase 2 vscode bindings), minimal WASI fd_write so println-style codegen works, exports.activate/exports.deactivate re-exports of the wasm module's same-named exports. .cjs output extension dispatches in bin/main.ml (both JSON and non-JSON paths). Smoke-tested: real Node 18 require()s a generated .cjs and successfully calls activate(fakeContext) → 0, deactivate() → 0. Issue #35 Phases 2-4 (stdlib/Vscode.affine bindings, extension.ts → extension.affine migration, rattlescript-face sweep) remain as separate work. (3) stdlib/Core.affine — three parser-collision fixes: `pub fn const[A,B]` → `always` (const is a reserved keyword for compile-time bindings); `fn(x: A) -> C { ... }` lambdas → `|x: A|` form (the parser's actual lambda syntax); `flip` rewritten from `(A, B) -> C` to curried `A -> B -> C` to dodge tuple-arrow ambiguity. The originally-blocked tests/modules/test_simple_import.affine (use Core::{min}; min(10,20)) now compiles end-to-end. Other stdlib files (Option/math/io/string/...) still don't parse — each has distinct issues (fn() type syntax, `[T]` array type per issues-drafts/02, `Option` angle brackets) that need their own passes or compiler-level fixes. (4) lib/module_loader.ml — new flatten_imports : t -> program -> program that prepends imported public TopFns into the importer's prog_decls (deduplicating against local fn names). bin/main.ml now binds [let flat_prog = Module_loader.flatten_imports loader prog in] in both compile_file paths and threads flat_prog through all 22 non-Wasm codegens (Julia, JS, C, WGSL, Faust, ONNX, OCaml, Lua, Bash, Nickel, ReScript, Rust, LLVM, Verilog, Gleam, CUDA, Metal, OpenCL, MLIR, Why3, Lean, SPIR-V) — Wasm and Wasm-GC keep the original prog because Codegen.gen_imports handles their cross-module needs natively. Smoke-tested: caller_ok.affine (use CrossCallee::{consume}) now compiles to JS / Julia / Rust / Lua with consume's body inlined. The non-JSON compile_file path also gained ~loader on its previously-loaderless Codegen.generate_module call (latent bug for cross-module wasm via this path). 188 → 190 tests; 0 regressions." +session-note-2026-05-03 = "TYPED-WASM CROSS-MODULE CLOSURE + MCP CARTRIDGE REWIRE + WASMGC LOUD-FAIL HARDENING. (1) lib/codegen.ml — generate_module gained ?loader and a new gen_imports pass that walks prog.prog_imports, loads each referenced module via Module_loader, and emits one (import \"\" \"\" (func ...)) entry per imported function plus a (local_alias_name → import_func_idx) entry in func_indices. ImportSimple is namespace-only (no emit), ImportList emits per item, ImportGlob enumerates public TopFns. Closes the cross-module WASM import emission gap called out in session-note-2026-04-19-a — `verify-boundary CALLEE.affine CALLER.affine` now works on user-authored AffineScript pairs, not just hand-assembled bridges. (2) lib/resolve.ml — import_resolved_symbols / import_specific_items / ImportGlob inline path now also write to dest type_ctx.name_types (not just var_types), with a new lookup_source_scheme helper that falls back from sym_id-keyed source_types to name-keyed source_name_types because resolve_and_typecheck_module's per-decl Typecheck.check_decl populates name_types but never var_types. lib/typecheck.ml — Typecheck.check_program gained ?import_types : (string, scheme) Hashtbl.t that seeds name_types after register_builtins, supplied by the resolver. bin/main.ml compile_file (JSON + non-JSON paths), compile_to_wasm_module, verify_file all updated to thread import_type_ctx.name_types through and pass ~loader to Codegen.generate_module. (3) test/e2e/fixtures/ — CrossCallee.affine + cross_caller_{ok,dup,drop}.affine, plus 3 new alcotest cases under E2E Boundary Verify exercising the full pipeline (parse → resolve_with_loader → typecheck-with-import-types → codegen-with-loader → Tw_interface.verify_cross_module). All three boundary outcomes (clean / LinearImportCalledMultiple / LinearImportDroppedOnSomePath) confirmed end-to-end. (4) boj-server/cartridges/typed-wasm-mcp — mod.js rewritten to call `affinescript` (was: nonexistent `typed-wasm` binary), with cwd set to the source's directory so Module_loader resolves relative imports correctly. cartridge.json bumped to v0.2.0 with corrected input descriptions (.affine source paths) and a new typed_wasm_verify_boundary tool exposing the cross-module verifier. README.adoc updated to match. (5) lib/codegen_gc.ml — eliminated three silent-bad-codegen fallbacks (same class as BUG-005): wildcard ExprLambda/ExprUnsafe → RefNull replaced with explicit UnsupportedFeature errors; match-arm wildcard PatTuple/PatRecord → fall-to-default replaced with UnsupportedFeature; PatLit fallback for LitFloat/LitString replaced with explicit errors. test/test_e2e.ml gained E2E WasmGC Loud-Fail suite with 2 regression markers.

(1) lib/codegen.ml commit 35c476d — three fixes: (a) PatCon-with-args stack imbalance in gen_pattern: was LocalTee match_result + LocalGet match_result around stack-neutral bind_fields; removed save/restore, I32Eq sits on stack directly. Fixes 'expected 1 elements on the stack for fallthru, found 2' on match-in-enum returning distinct zero-arity or arg constructors across arms. (b) ExprVar falls back to ctx.variant_tags when lookup_local misses, so bare `Initialised` (parens omitted) resolves as the variant tag — parser accepts the form, codegen previously failed with UnboundVariable. (c) ctx.struct_layouts + ctx.fn_ret_structs: struct layouts registered globally from TopType(TyStruct), propagated to function parameters via p_ty, call-result lets via fn_ret_structs, let-bindings with sl_ty annotation, let-from-let passthroughs. Fixes the .field_1_or_later=0 bug on struct function parameters. struct_name_of_ty handles TyCon / TyApp / TyOwn / TyRef / TyMut wrappers. (2) bin/main.ml commit f6089a2 — new verify-boundary CALLEE CALLER subcommand: compiles two .affine source files, extracts callee's ownership-annotated export interface, runs Tw_interface.verify_cross_module on the caller, exits 0/1 correctly. Shared compile_to_wasm_module helper factored out of verify_file. Fixed verify_boundary_fn exit-code bug (verify-bridge handler): was always returning Ok () even on violations; now tracks violation count and maps to Error so CI catches boundary drift. Level 10 cross-module boundary verifier now has public CLI surface. Evidence: 177/177 tests green unchanged; affinescript-deno-test smoke suite 7/7 (up from 4/4) with new codegen_regression_test.affine; double-track-browser extension_lifecycle_test.affine pilot 10/10 without tagged-struct workaround. Scope note: AffineScript use A.B imports inline at AST layer, so caller from AffineScript source today produces no cross-module WASM imports — new CLI immediately useful for hand-assembled / bridge-pattern callers (IDApTIK bridges, composition tools).

(1) `fn(A, B, ...) -> T` lowers to the curried arrow chain `A -> B -> ... -> T`. Zero-arg `fn() -> T` lowers to `Unit -> T` (TyTuple [] -> T). Required by stdlib/Option.affine's `unwrap_or_else[T](opt: Option[T], f: fn() -> T) -> T` and similar higher-order signatures. (2) Angle-bracket aliases for type application AND type parameters: `Option` ≡ `Option[T]`, `fn f(x: T)` ≡ `fn f[T](x: T)`, `type Option = ...` ≡ `type Option[T] = ...`. The `<` / `>` are unambiguous in type position because comparison operators don't appear there. (3) `(A, B) -> C` now lowers to the curried arrow `A -> B -> C` instead of being parsed as a single tuple-arg arrow. Disambiguated from plain tuple types by the trailing ARROW; bare `(A, B)` (no arrow) still parses as a TyTuple. Stdlib/Core.affine's `flip` reverted from the earlier curried workaround to its natural `(A, B) -> C` form.

(2) packages/affine-vscode/mod.js refactored to take the host shim as 3rd arg and share its handle table — fixes a bug where the wasm-side ExtensionContext handle wasn't visible to adapter functions. lib/codegen_node.ml's shim now exposes exports._instance + exports._memory after init so adapters can read string args out of wasm linear memory; replaces the constant `_extraImports()` with a mutable exports.extraImports hook.
