# Phase 15 — Box Stacking Roadmap (Living)
|
||
|
||
This roadmap is a living checklist to advance Phase 15 with small, safe boxes. Update continuously as we progress.
|
||
|
||
## Now (ready/green)
|
||
|
||
- [x] v0 Ny parser (Ny→JSON IR v0) with wrappers (Unix/Windows)
|
||
- [x] Runner JSON v0 bridge (`--ny-parser-pipe`) → MIR → MIR-Interp
|
||
- [x] E2E + roundtrip practical recipes (Windows/Unix)
|
||
- [x] Docs path unify (phase-15 under roadmap tree)
|
||
- [x] Direct bridge (design + skeleton; feature-gated)
|
||
- [x] AOT P2 stubs (CraneliftAotBox/LinkerBox) + RUN smoke wiring
|
||
- [x] JIT‑only baseline stabilized (core smokes green; plugins optional)
|
||
- [x] Roundtrip (Case A/B) aligned; Case A re‑enabled via parser pipe
|
||
- [x] using/namespace (gated) + nyash.link minimal resolver
|
||
- [x] NyModules + ny_plugins regression suite (Windows path normalization/namespace derivation)
|
||
- [x] Standard Ny scripts scaffolds added (string/array/map P0) + examples + jit_smoke
|
||
- [x] Selfhost Parser accepts positional input file arg（EXE運用の前提）
|
||
- [x] **Phase 15.5-A: プラグインチェッカー拡張完成**（ChatGPT5 Pro⭐⭐⭐⭐⭐最高評価）
|
||
- ✅ 4つの安全性機能完全実装（ユニバーサルスロット衝突・StringBox問題・E_METHOD・TLV検証）
|
||
- ✅ 100%検出精度実証（手動発見問題を完全自動検出）
|
||
- ✅ 実用検証済み（実際のnyash.tomlで8問題自動検出・修正指示）
|
||
- [x] **Phase 15.5-B-1: slot_registry統一化完成**（StringBox問題根本修正）
|
||
- ✅ core box静的定義30行削除完了（3-tier→2-tier基盤確立）
|
||
- ✅ former core boxes（StringBox/IntegerBox/ArrayBox/MapBox）のplugin slots移行
|
||
- ✅ WebChatGPT環境との完全一致（同じnyash.toml設定で同じ動作）
|
||
|
||
## Next (small boxes)
|
||
|
||
1) Ny JSON ライブラリ（最小 DOM / JSON v0 対応）
|
||
- Nyash 製の parse/stringify（object/array/string/number/bool/null）。
|
||
- Env: `NYASH_JSON_PROVIDER=ny`（既定OFF）。
|
||
- Smokes: roundtrip/エラー位置検証（quick 任意; CI非ブロック）。
|
||
2) Ny Executor（最小命令セット）
|
||
- ops: const/binop/compare/branch/jump/ret/phi（Box 呼び出しは後段）。
|
||
- Env: `NYASH_SELFHOST_EXEC=1`（既定OFF）。
|
||
- Parity: PyVM/LLVM harness と stdout/exit の一致。
|
||
3) 呼び出し最小（Console/String/Array/Map P0）
|
||
- call/externcall/boxcall の最小を接続。未知 extern は STRICT で拒否。
|
||
4) Selfhost Parser の EXE 化（任意・後回し可）
|
||
- `tools/build_compiler_exe.sh` により JSON v0 emit の単体配布（開発者向け）。
|
||
5) PHI 自動化は Phase‑15 後（LoopForm = MIR18）
|
||
- Phase‑15: 現行の Bridge‑PHI を維持（規約は「incoming pred=実際の遷移元」）。
|
||
- MIR18: LoopForm 強化＋逆Loweringでの自動化に委譲（設計のみ先行）。
|
||
6) Plugins CI split（継続）
|
||
- Plugins は任意ジョブ（strict off）を維持。Core は軽量 quick を常時。
|
||
|
||
## Later (incremental)
|
||
|
||
- v1 Ny parser (let/if/call) behind `NYASH_JSON_IR_VERSION=1`
|
||
- JSON v1 bridge → MirBuilder (back-compat v0)
|
||
- 12.7 sugars normalized patterns in bridge (?. / ?? / range)
|
||
- E2E CI-lite matrix (no LLVM) for v0/v1/bridge roundtrip
|
||
- Ny script plugin examples under `apps/plugins-scripts/`
|
||
- Expand std Ny impl (String P1: trim/split/startsWith/endsWith; Array P1: map/each/filter; Map P1: values/entries/forEach)
|
||
- using/nyash.link E2E samples under `apps/` (small project template)
|
||
- Tighten Plugins job: migrate samples to Core‑13; re‑enable strict diagnostics
|
||
|
||
## Operational switches
|
||
|
||
- Parser path: `--parser {rust|ny}` or `NYASH_USE_NY_PARSER=1`
|
||
- JSON dump: `NYASH_DUMP_JSON_IR=1`
|
||
- （予告）LoopForm: MIR18 で仕様化予定
|
||
- Selfhost compiler: `NYASH_USE_NY_COMPILER=1`, child quiet: `NYASH_JSON_ONLY=1`
|
||
- JSON provider: `NYASH_JSON_PROVIDER=ny`（Ny JSON; 既定OFF）
|
||
- Ny executor: `NYASH_SELFHOST_EXEC=1`（既定OFF）
|
||
- EXE-first bundle: `tools/build_compiler_exe.sh` → `dist/nyash_compiler/`
|
||
- Load Ny plugins: `NYASH_LOAD_NY_PLUGINS=1` / `--load-ny-plugins`
|
||
- AOT smoke: `CLIF_SMOKE_RUN=1`
|
||
|
||
## Recipes / Smokes
|
||
|
||
- JSON v0 bridge: `tools/ny_parser_bridge_smoke.sh` / `tools/ny_parser_bridge_smoke.ps1`
|
||
- E2E roundtrip: `tools/ny_roundtrip_smoke.sh` / `tools/ny_roundtrip_smoke.ps1`
|
||
- EXE-first smoke: `tools/build_compiler_exe.sh && (cd dist/nyash_compiler && ./nyash_compiler tmp/sample.hako > sample.json)`
|
||
|
||
## Implementation Dependencies
|
||
|
||
- Phase 15.2 (LLVM EXE) → Phase 15.3 (Nyash Compiler) → Phase 15.4 (VM in Nyash)
|
||
- Python llvmlite serves as rapid prototyping path while Rust/inkwell continues
|
||
- Plugin all-direction build enables static executable generation
|
||
- Total expected Nyash code: ~20,000 lines (75% reduction from 80k Rust)
|
||
|
||
## Stop criteria (Phase 15)
|
||
|
||
- v0 E2E green (parser pipe + direct bridge) including Ny compiler MVP switch
|
||
- v1 minimal samples pass via JSON bridge
|
||
- AOT P2: emit→link→run stable for constant/arith
|
||
- Phase‑15 STOP には PHI 切替を含めない（PHI は LoopForm/MIR18 で扱う）
|
||
- 15.3: Stage‑1 代表サンプル緑 + Bootstrap smoke（フォールバック許容）+ 文分離ポリシー公開
|
||
- Docs/recipes usable on Windows/Unix
|
||
|
||
## Notes
|
||
|
||
- JSON is a temporary, safe boundary. We will keep it for observability even after the in-proc bridge is default.
|
||
- Favor smallest viable steps; do not couple large refactors with new features.
|
||
|
||
## Ny Plugins → Namespace (Plan)
|
||
|
||
- Phase A (minimal): Add a shared `NyModules` registry (env.modules.{set,get}).
|
||
- Map file path → namespace (project‑relative, separators → `.`, trim extension).
|
||
- R5 hook: if a Ny plugin returns an exports map/static box, register it under the derived namespace.
|
||
- Guard: reject reserved prefixes (e.g., `nyashstd.*`, `system.*`).
|
||
- Phase B (scope): Optionally run `[ny_plugins]` in a shared Interpreter to share static definitions.
|
||
- Flag: `NYASH_NY_PLUGINS_SHARED=0` to keep isolated execution.
|
||
- Logs: `[ny_plugins] <ns>: REGISTERED | FAIL(reason)`.
|
||
- Phase C (language bridge): Resolve `using foo.bar` via `NyModules`, then fallback to file/package resolver (nyash.link).
|
||
- Keep IDE‑friendly fully qualified access; integrate with future `nyash_modules/`.
