# 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
|
||
|
||
## Next (small boxes)
|
||
|
||
1) LLVM Native EXE Generation (Phase 15.2) 🚀
|
||
- Python/llvmlite implementation as primary path (2400 lines, 10x faster development)
|
||
- LLVM backend object → executable pipeline completion
|
||
- Separate `nyash-llvm-compiler` crate (reduce main build weight)
|
||
- Input: MIR (JSON/binary) → Output: native executable
|
||
- Link with nyrt runtime (static/dynamic options)
|
||
- Plugin all-direction build strategy (.so/.o/.a simultaneous generation)
|
||
- Integration: `nyash --backend llvm --emit exe program.nyash -o program.exe`
|
||
2) Standard Ny std impl (P0→実体化)
|
||
- Implement P0 methods for string/array/map in Nyash (keep NyRT primitives minimal)
|
||
- Enable via `nyash.toml` `[ny_plugins]` (opt‑in); extend `tools/jit_smoke.sh`
|
||
3) Ny compiler MVP (Ny→MIR on JIT path) (Phase 15.3) 🎯
|
||
- Ny tokenizer + recursive‑descent parser (current subset) in Ny; drive existing MIR builder
|
||
- Target: 800 lines parser + 2500 lines MIR builder = 3300 lines total
|
||
- No circular dependency: nyrt provides StringBox/ArrayBox via C ABI
|
||
- Flag path: `NYASH_USE_NY_COMPILER=1` to switch rust→ny compiler; rust parser as fallback
|
||
- Add apps/selfhost-compiler/ and minimal smokes
|
||
4) Bootstrap loop (c0→c1→c1')
|
||
- Use existing trace/hash harness to compare parity; add optional CI gate
|
||
- **This achieves self-hosting!** Nyash compiles Nyash
|
||
5) VM Layer in Nyash (Phase 15.4) ⚡
|
||
- Implement MIR interpreter in Nyash (13 core instructions)
|
||
- Dynamic dispatch via MapBox for instruction handlers
|
||
- BoxCall/ExternCall bridge to existing infrastructure
|
||
- Optional LLVM JIT acceleration for hot paths
|
||
- Enable instant execution without compilation
|
||
- Expected: 5000 lines for complete VM implementation
|
||
6) Plugins CI split (継続)
|
||
- Core always‑on (JIT, plugins disabled); Plugins as optional job (strict off by default)
|
||
|
||
## 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`
|
||
- 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`
|
||
|
||
## 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
|
||
- 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/`.
