# PHI and SSA in Nyash
|
||||
# Moved: PHI and SSA
|
||||
|
||||
Overview
|
||||
- Nyash lowers high-level control flow (If/Loop/Match) to MIR and backends that rely on SSA form.
|
||||
- We prioritize IR hygiene and observability while keeping runtime cost at zero.
|
||||
このドキュメントは再編により移動しました。
|
||||
新しい場所: [../reference/architecture/phi-and-ssa.md](../reference/architecture/phi-and-ssa.md)
|
||||
|
||||
Design points
|
||||
- PHI hygiene: no empty PHIs; PHIs at block head only.
|
||||
- JoinResult hint: when both branches assign the same variable, we emit a MIR hint for diagnostics.
|
||||
- Loop carriers: loops may expose a carrier observation (≤ N variables, where N is unconstrained by design; smokes emphasize common cases).
|
||||
|
||||
Normalization
|
||||
- If: may optionally wrap into LoopForm under a conservative gate (dev only). Semantics remain unchanged.
|
||||
- Match: scrutinee evaluated once, guard fused; normalized to nested If‑chain in macro/core pass.
|
||||
|
||||
Testing
|
||||
- LLVM smokes: fixed small cases ensure no empty PHIs and head placement.
|
||||
- MIR smokes: trace `scope|join|loop` to validate shaping without peeking into IR details.
|
||||
|
||||
Roadmap
|
||||
- Remove text-level sanitization once finalize‑PHI is trustworthy across Loop/If/Match.
|
||||
- Expand goldens to cover nested joins and multi‑carrier loops while keeping CI light.

# Strings Blueprint — UTF‑8 First, Bytes Separate

# Moved: Strings Blueprint — UTF‑8 / Bytes
|
||||
|

Status: active (Feature‑Pause compatible)
|
||||
Updated: 2025-09-21
|
||||
このドキュメントは再編により移動しました。
|

新しい場所: [../development/design/blueprints/strings-utf8-byte.md](../development/design/blueprints/strings-utf8-byte.md)
|
||||
|
||||
Purpose
|
||||
- Unify string semantics by delegating StringBox public APIs to dedicated cursor boxes.
|
||||
- Keep behavior stable while making codepoint vs byte decisions explicit and testable.
|
||||
この stub は後方互換のために残しています。
|
||||
|
||||
Pillars
|
||||
- Utf8CursorBox (codepoint-oriented)
|
||||
- length/indexOf/substring operate on UTF‑8 codepoints.
|
||||
- Intended as the default delegate for StringBox public APIs.
|
||||
- ByteCursorBox (byte-oriented)
|
||||
- length/indexOf/substring operate on raw bytes.
|
||||
- Use explicitly for byte-level parsing or binary protocols.
|
||||
|
||||
Delegation Strategy
|
||||
- StringBox delegates to Utf8CursorBox for core methods: length/indexOf/substring.
|
||||
- Provide conversion helpers: toUtf8Cursor(), toByteCursor() (thin wrappers).
|
||||
- Prefer delegation over inheritance; keep “from” minimal to avoid API ambiguity.
|
||||
|
||||
API Semantics
|
||||
- indexOf: define two flavors via the box boundary.
|
||||
- StringBox.indexOf → Utf8CursorBox.indexOf (CP-based; canonical)
|
||||
- ByteCursorBox.indexOf → byte-based; opt‑in only
|
||||
- substring: follow the same split (CP vs Byte). Do not mix semantics.
|
||||
- Document preconditions for indices (out‑of‑range clamped/errored per guide).
|
||||
|
||||
Implementation Plan (staged, non‑breaking)
|
||||
1) Provide MVP cursor boxes (done)
|
||||
- apps/libs/utf8_cursor.nyash
|
||||
- apps/libs/byte_cursor.nyash
|
||||
2) Delegate StringBox public methods to Utf8CursorBox (internal only; behavior unchanged)
|
||||
- Start with length → indexOf → substring
|
||||
- Add targeted smokes for edge cases (multi‑byte CP, boundaries)
|
||||
3) Replace ad‑hoc scans in Nyash scripts with cursor usage (Mini‑VM/macros)
|
||||
- Migrate internal scanners (no external behavior change)
|
||||
4) Introduce ByteCursorBox only where byte‑level semantics are required
|
||||
- Keep call sites explicit to avoid ambiguity
|
||||
|
||||
Transition Gate (Rust dev only)
|
||||
- Env `NYASH_STR_CP=1` enables CP semantics for legacy byte-based paths in Rust runtime (e.g., StringBox.length/indexOf/lastIndexOf).
|
||||
- Default remains byte in Rust during the feature‑pause; PyVM follows CP semantics. CI smokes validate CP behavior via PyVM.

|
||||
|
||||
Testing Notes
|
||||
- Keep PyVM as the reference execution path.
|
||||
- Add smokes: CP boundaries, mixed ASCII/non‑ASCII, indexOf not found, substring slices.
|
||||
- Avoid perf work; focus on semantics + observability.

# Flow Blocks and Arrow Piping (Design Draft)
|
||||
# Moved: Flow Blocks (Design Draft)
|
||||
|
||||
Status: design-only during the feature‑pause (no implementation)
|
||||
このドキュメントは再編により移動しました。
|
||||
新しい場所: [../development/design/legacy/flow-blocks.md](../development/design/legacy/flow-blocks.md)
|
||||
|
||||
Goal
|
||||
- Make control/data flow visually obvious while keeping the core minimal.
|
||||
- Core = anonymous `{ ... }` blocks + `->` chaining with `_` or `|args|` as the input placeholder.
|
||||
- Always desugar to plain sequential let/if/call; zero new runtime constructs.
|
||||
|
||||
Core Syntax
|
||||
- Serial (value flow):
|
||||
```nyash
|
||||
{ readConfig() }
|
||||
-> { |cfg| validate(cfg) }
|
||||
-> { |cfg| normalize(cfg) }
|
||||
-> { |cfg| save(cfg) }
|
||||
```
|
||||
- Placeholder short form:
|
||||
```nyash
|
||||
{ fetch() } -> { process(_) } -> { output(_) }
|
||||
```
|
||||
- If/Else with horizontal flow:
|
||||
```nyash
|
||||
if cond -> { doA() } else -> { doB() }
|
||||
```
|
||||
|
||||
Semantics
|
||||
- `{ ... }` is an anonymous scope usable as expression or statement.
|
||||
- `->` passes the left result as the first parameter of the right block.
|
||||
- Left returns `Void` → right cannot use `_`/`|x|` (compile-time error in MVP spec).
|
||||
- `_` and `|x,...|` are exclusive; mixing is an error.
|
||||
|
||||
Lowering (always zero-cost sugar)
|
||||
- Chain desugars to temporaries and calls:

||||
```nyash
|
||||
# {A} -> { |x| B(x) } -> { |y| C(y) }
|
||||
t0 = A();
|
||||
t1 = B(t0);
|
||||
t2 = C(t1);
|
||||
```
|
||||
- If/Else chain desugars to standard if/else blocks; merges follow normal PHI wiring rules.
|
||||
|
||||
Match normalization via guard chains
|
||||
- Prefer a single readable form:
|
||||
```nyash
|
||||
guard cond1 -> { A }
|
||||
guard cond2 -> { B }
|
||||
else -> { C }
|
||||
```
|
||||
- Lowers to first-match if/else chain. No new pattern engine is introduced.
|
||||
|
||||
Range and CharClass guards (design)
|
||||
- Range: `guard ch in '0'..'9' -> { ... }` → `('0' <= ch && ch <= '9')`.
|
||||
- CharClass: `guard ch in Digit -> { ... }` → expands to ranges (e.g., '0'..'9').
|
||||
- Multiple ranges combine with OR.
|
||||
|
||||
Formatting (nyfmt guidance)
|
||||
- Align arrows vertically; one step per line:
|
||||
```
|
||||
{ fetch() }
|
||||
-> { validate(_) }
|
||||
-> { save(_) }
|
||||
```
|
||||
- Suggest factoring when chains exceed N steps; prefer naming a scope helper.
|
||||
|
||||
Observability (design only)
|
||||
- `NYASH_FLOW_TRACE=1` prints the desugared steps (`t0=...; t1=...;`).
|
||||
|
||||
Constraints (MVP)
|
||||
- No new closures; anonymous blocks inline when capture-free.
|
||||
- Recursion not required; focus on linear/branching chains.
|
||||
- ASI: treat `->` as a low-precedence line-continue operator.
|
||||
|
||||
Tests (syntax-only smokes; design)
|
||||
- flow_linear: `read→validate→save` matches expected value.
|
||||
- flow_placeholder: `{f()} -> { process(_) } -> { out(_) }`.
|
||||
- flow_if: `if cond -> {A} else -> {B}` behaves like standard if.
|
||||
|
||||
Pause note
|
||||
- Documentation and design intent only. Implementation is deferred until after the feature‑pause (post‑bootstrap).

# Moved: Using → Loader Integration (Minimal)
|
||||
|
||||
Goal
|
||||
- Keep `using` simple: strip lines and resolve names to paths/aliases.
|
||||
- Add the minimal integration so userland boxes referenced via `using` are actually available at compile/run time.
|
||||
このドキュメントは再編により移動しました。
|
||||
新しい場所: [../development/design/legacy/using-loader-integration.md](../development/design/legacy/using-loader-integration.md)
|
||||
|
||||
Scope (pause‑safe)
|
||||
- Parser stays Phase‑0: keep `nyashstd` restriction; do not widen grammar.
|
||||
- Integration is a runner step (pre‑parse): resolve and register modules; do not change language semantics.
|
||||
|
||||
Design
|
||||
- Strip `using` lines when `NYASH_ENABLE_USING=1` (already implemented).
|
||||
- For each `using ns [as alias]?`:
|
||||
- Resolve `ns` → path via: [modules] → aliases → using.paths (apps/lib/.) → context dir.
|
||||
- Register mapping in `modules_registry` as `alias_or_ns -> path` (already implemented).
|
||||
- Minimal loader hook (defer heavy linking):
|
||||
- Compile/execute entry file as today.
|
||||
- Userland boxes are accessed via tools/runners that read from `modules_registry` where needed (e.g., PyVM harness/tests).
|
||||
|
||||
Notes
|
||||
- Entry thin‑ization (Mini‑VM) waits until loader reads userland boxes on demand.
|
||||
- Keep docs small: this note serves as the canonical link; avoid duplicating details in other pages.
|
||||
|
||||
Preprocessing invariants (runner)
|
||||
- `using` lines are stripped and resolved prior to parse; dependencies are inlined before `Main` so names are available without changing language semantics.
|
||||
- Line‑head `@name[:T] = expr` is normalized to `local name[:T] = expr` as a purely textual pre‑expand (no semantic change). Inline `@` is not recognized; keep `@` at line head.
|
||||
- These steps are pause‑safe: they do not alter AST semantics; they only simplify authoring and module wiring.

# ADR-001: No CoreBox, Everything is Plugin — Provider/Type 分離方針
|
||||
|
||||
Status: Accepted (Phase 15.5 設計)
|
||||
Last updated: 2025-09-26
|
||||
|
||||
## 決定
|
||||
|
||||
- CoreBox（言語ランタイム内の特別な箱実装）は復活させない。
|
||||
- 最小カーネル（NyKernel）は GC/Handle/TLV/Extern/PluginRegistry/ABI だけを提供し、箱の実装は一切持たない。
|
||||
- 機能はすべて Plugin（TypeBox v2）で提供する（Everything is Plugin）。
|
||||
- 型名（Stable Type Name: STN）と実装提供者（Provider ID: PVN）を分離する。
|
||||
- 例: STN = `StringBox`、PVN = `kernel:string@1.0` / `acme:string@2.1`。
|
||||
- コードは常に STN に依存し、どの PVN を使うかは `nyash.toml` で選択する。
|
||||
- 起動シーケンスは「Kernel init → plugins.bootstrap（静的束）+ plugins.dynamic（任意）登録 → Verify（必須メソッド等）→ 実行」。
|
||||
- 呼び出しは VM/LLVM 共通で `ny_new_box` / `ny_call_method` に一本化（MIR Callee 確定から統一）する。
|
||||
|
||||
## 背景 / 文脈
|
||||
|
||||
- using の SSOT（唯一の真実）を `nyash.toml` に置き、実体結合は AST マージに一本化した。これにより宣言≻式の曖昧性を排除し、依存は設定で一元管理できる。
|
||||
- CoreBox を残すと特別経路や例外が増え、Everything is Plugin と相反する。Kernel/Plugin の責務分離が維持性と置換性を高める。
|
||||
|
||||
## 設計詳細
|
||||
|
||||
### NyKernel の責務
|
||||
- GC / Roots / Safepoint / Write barrier
|
||||
- Handle / TLV
|
||||
- Extern registry（`env.console.*` 最小）
|
||||
- Plugin registry（登録・検索・呼び出し）
|
||||
- C ABI: `ny_new_box(type_id, args)`, `ny_call_method(recv, type_id, method_id, args, out)`, `ny_gc_*`
|
||||
|
||||
### Bootstrap Pack（静的リンクの基本プラグイン束）
|
||||
- String/Integer/Array/Map/Console などの最小実用セット。
|
||||
- 静的リンクして起動時に一括登録（特権経路は作らない）。
|
||||
- 動的プラグインで override 可能（ポリシーで制御）。
|
||||
|
||||
### Provider/Type 分離（TOML スキーマ案・既定OFF）
|
||||
```toml
|
||||
[types.StringBox]
|
||||
provider = "kernel:string@1.0"
|
||||
allow_override = true
|
||||
|
||||
[providers."kernel:string@1.0"]
|
||||
crate = "nyash-plugin-base-string"
|
||||
|
||||
[providers."acme:string@2.1"]
|
||||
path = "./plugins/libacme_string.so"
|
||||
override = true
|
||||
|
||||
[policy]
|
||||
factory = "plugin-first" # compat_plugin_first | static_only
|
||||
```
|
||||
|
||||
### Verify（必須）
|
||||
- plugin-tester で Lifecycle/TLV/必須メソッドを検証。欠落時は即エラー。
|
||||
|
||||
## 代替案の却下（kernelString 等）
|
||||
|
||||
- 型名に provider を織り込む（例: `kernelString`）案は、差し替え不能化・特権化・型ID安定性の破壊リスクが高く不採用。区別は provider 名で行い、型名（STN）は常に不変とする。
|
||||
|
||||
## ロードマップ（小さく段階的・既定OFF）
|
||||
- K0: ADR/Docs 追加（本書）。
|
||||
- K1: TOML スキーマの雛形（types/providers/policy）を docs と設定ローダに受け口だけ追加（挙動不変）。
|
||||
- K2: 起動時に provider 解決の受け口をログ出力のみで導入（挙動不変）。
|
||||
- K3: Verify フックを preflight_plugins に統合（既定OFF）。
|
||||
- K4: Bootstrap Pack の登録導線（prod 限定フラグ・既定OFF）。
|
||||
|
||||
## 移行 / 互換
|
||||
- 既存コードは型名（STN）のまま変更不要。provider 置換は TOML で完結。
|
||||
- VM fallback の暫定個別救済はフラグ付き/短期で撤去。最終形は `ny_call_method` に集約。

# Strings Blueprint — UTF‑8 First, Bytes Separate
|
||||
|
||||
Status: active (Feature‑Pause compatible)
|
||||
Updated: 2025-09-21
|
||||
|
||||
Purpose
|
||||
- Unify string semantics by delegating StringBox public APIs to dedicated cursor boxes.
|
||||
- Keep behavior stable while making codepoint vs byte decisions explicit and testable.
|
||||
|
||||
Pillars
|
||||
- Utf8CursorBox (codepoint-oriented)
|
||||
- length/indexOf/substring operate on UTF‑8 codepoints.
|
||||
- Intended as the default delegate for StringBox public APIs.
|
||||
- ByteCursorBox (byte-oriented)
|
||||
- length/indexOf/substring operate on raw bytes.
|
||||
- Use explicitly for byte-level parsing or binary protocols.
|
||||
|
||||
Delegation Strategy
|
||||
- StringBox delegates to Utf8CursorBox for core methods: length/indexOf/substring.
|
||||
- Provide conversion helpers: toUtf8Cursor(), toByteCursor() (thin wrappers).
|
||||
- Prefer delegation over inheritance; keep “from” minimal to avoid API ambiguity.
|
||||
|
||||
API Semantics
|
||||
- indexOf: define two flavors via the box boundary.
|
||||
- StringBox.indexOf → Utf8CursorBox.indexOf (CP-based; canonical)
|
||||
- ByteCursorBox.indexOf → byte-based; opt‑in only
|
||||
- substring: follow the same split (CP vs Byte). Do not mix semantics.
|
||||
- Document preconditions for indices (out‑of‑range clamped/errored per guide).
|
||||
|
||||
Implementation Plan (staged, non‑breaking)
|
||||
1) Provide MVP cursor boxes (done)
|
||||
- apps/libs/utf8_cursor.nyash
|
||||
- apps/libs/byte_cursor.nyash
|
||||
2) Delegate StringBox public methods to Utf8CursorBox (internal only; behavior unchanged)
|
||||
- Start with length → indexOf → substring
|
||||
- Add targeted smokes for edge cases (multi‑byte CP, boundaries)
|
||||
3) Replace ad‑hoc scans in Nyash scripts with cursor usage (Mini‑VM/macros)
|
||||
- Migrate internal scanners (no external behavior change)
|
||||
4) Introduce ByteCursorBox only where byte‑level semantics are required
|
||||
- Keep call sites explicit to avoid ambiguity
|
||||
|
||||
Transition Gate (Rust dev only)
|
||||
- Env `NYASH_STR_CP=1` enables CP semantics for legacy byte-based paths in Rust runtime (e.g., StringBox.length/indexOf/lastIndexOf).
|
||||
- Default remains byte in Rust during the feature‑pause; PyVM follows CP semantics. CI smokes validate CP behavior via PyVM.

Box Foundations (string-related)
|
||||
- Utf8CursorBox, ByteCursorBox
|
||||
- StringExtBox (trim/startsWith/endsWith/replace/split)
|
||||
- StringBuilderBox (append/toString)
|
||||
- JsonCursorBox (lightweight JSON scanning helpers)
|
||||
|
||||
Testing Notes
|
||||
- Keep PyVM as the reference execution path.
|
||||
- Add smokes: CP boundaries, mixed ASCII/non‑ASCII, indexOf not found, substring slices.
|
||||
- Avoid perf work; focus on semantics + observability.

# Flow Blocks and Arrow Piping (Design Draft)
|
||||
|
||||
Status: design-only during the feature‑pause (no implementation)
|
||||
|
||||
Goal
|
||||
- Make control/data flow visually obvious while keeping the core minimal.
|
||||
- Core = anonymous `{ ... }` blocks + `->` chaining with `_` or `|args|` as the input placeholder.
|
||||
- Always desugar to plain sequential let/if/call; zero new runtime constructs.
|
||||
|
||||
Core Syntax
|
||||
- Serial (value flow):
|
||||
```nyash
|
||||
{ readConfig() }
|
||||
-> { |cfg| validate(cfg) }
|
||||
-> { |cfg| normalize(cfg) }
|
||||
-> { |cfg| save(cfg) }
|
||||
```
|
||||
- Placeholder short form:
|
||||
```nyash
|
||||
{ fetch() } -> { process(_) } -> { output(_) }
|
||||
```
|
||||
- If/Else with horizontal flow:
|
||||
```nyash
|
||||
if cond -> { doA() } else -> { doB() }
|
||||
```
|
||||
|
||||
Semantics
|
||||
- `{ ... }` is an anonymous scope usable as expression or statement.
|
||||
- `->` passes the left result as the first parameter of the right block.
|
||||
- Left returns `Void` → right cannot use `_`/`|x|` (compile-time error in MVP spec).
|
||||
- `_` and `|x,...|` are exclusive; mixing is an error.
|
||||
|
||||
Lowering (always zero-cost sugar)
|
||||
- Chain desugars to temporaries and calls:
|
||||
```nyash
|
||||
# {A} -> { |x| B(x) } -> { |y| C(y) }
|
||||
t0 = A();
|
||||
t1 = B(t0);
|
||||
t2 = C(t1);
|
||||
```
|
||||
- If/Else chain desugars to standard if/else blocks; merges follow normal PHI wiring rules.
|
||||
|
||||
Match normalization via guard chains
|
||||
- Prefer a single readable form:
|
||||
```nyash
|
||||
guard cond1 -> { A }
|
||||
guard cond2 -> { B }
|
||||
else -> { C }
|
||||
```
|
||||
- Lowers to first-match if/else chain. No new pattern engine is introduced.
|
||||
|
||||
Range and CharClass guards (design)
|
||||
- Range: `guard ch in '0'..'9' -> { ... }` → `('0' <= ch && ch <= '9')`.
|
||||
- CharClass: `guard ch in Digit -> { ... }` → expands to ranges (e.g., '0'..'9').
|
||||
- Multiple ranges combine with OR.
|
||||
|
||||
Formatting (nyfmt guidance)
|
||||
- Align arrows vertically; one step per line:
|
||||
```
|
||||
{ fetch() }
|
||||
-> { validate(_) }
|
||||
-> { save(_) }
|
||||
```
|
||||
- Suggest factoring when chains exceed N steps; prefer naming a scope helper.
|
||||
|
||||
Observability (design only)
|
||||
- `NYASH_FLOW_TRACE=1` prints the desugared steps (`t0=...; t1=...;`).
|
||||
|
||||
Constraints (MVP)
|
||||
- No new closures; anonymous blocks inline when capture-free.
|
||||
- Recursion not required; focus on linear/branching chains.
|
||||
- ASI: treat `->` as a low-precedence line-continue operator.
|
||||

||||

- flow_linear: `read→validate→save` matches expected value.
|
||||
- flow_placeholder: `{f()} -> { process(_) } -> { out(_) }`.

- flow_if: `if cond -> {A} else -> {B}` behaves like standard if.

# Nyash Concurrency — Box Model (Proposal, docs-only)
|
||||
|
||||
Status: design-only during the feature‑pause. No runtime or spec changes. Implement after Mini‑VM baseline is stable.
|
||||
|
||||
Intent
|
||||
- Bring Go-like CSP (goroutine/channels/select) into Nyash via “Everything is Box”.
|
||||
- Keep semantics explicit, lifecycle safe (birth/fini), and observable. Phase-in from userland → runtime.
|
||||
|
||||
Scope (Phase‑0: userland MVP)
|
||||
- RoutineBox: lightweight task wrapper over `nowait` (state, join/cancel, status).
|
||||
- ChannelBox: bounded/unbounded queue + blocking/non-blocking ops + close semantics.
|
||||
- SelectBox: multi-channel wait (first-ready) with simple fairness.
|
||||
- RoutineScopeBox: structured concurrency; children are canceled on scope fini.
|
||||
- Observability: JSONL trace toggled by `NYASH_CONC_TRACE=1`.
|
||||
|
||||
Non‑Goals (Phase‑0)
|
||||
- M:N scheduler, OS-level park/unpark, net poller integration (deferred to Phase‑2 runtime work).
|
||||
|
||||
API Sketch (userland)
|
||||
- RoutineBox
|
||||
- birth(fn)
|
||||
- start(): Void
|
||||
- join(timeout_ms?: Int) -> Bool // true if joined; false on timeout
|
||||
- cancel(): Void
|
||||
- status() -> String // ready|running|done|canceled|error
|
||||
- ChannelBox(capacity: Int=0)
|
||||
- send(v): Void // blocks if full (Phase‑0: simulated park)
|
||||
- try_send(v) -> Bool
|
||||
- receive() -> Any // blocks if empty (Phase‑0: simulated park)
|
||||
- try_receive() -> (Bool, Any?)
|
||||
- receive_timeout(ms: Int) -> (Bool, Any?)
|
||||
- close(): Void // further send fails; recv drains until empty then End
|
||||
- SelectBox
|
||||
- birth()
|
||||
- when(ch: ChannelBox, handler: Fn): Void
|
||||
- await() -> Bool // returns after one handler runs; false if none ready and no wait policy
|
||||
- await_timeout(ms: Int) -> Bool
|
||||
- RoutineScopeBox
|
||||
- birth()
|
||||
- spawn(fn) -> RoutineBox
|
||||
- fini() // cancels pending routines and waits boundedly
|
||||
|
||||
Semantics
|
||||
- Capacity:
|
||||
- 0: rendezvous channel (send/recv rendezvous).
|
||||
- N>0: bounded ring buffer.
|
||||
- Close:
|
||||
- close() marks channel as closed. send() after close -> error. receive() returns buffered items; when empty -> (false, End) style result; exact return shape defined per API.
|
||||
- Blocking:
|
||||
- Phase‑0 userland uses cooperative wait queues; no busy loops. try_* and timeout variants provided.
|
||||
- Select fairness:
|
||||
- If multiple ready, choose random/round‑robin. Starvation avoidance is a design requirement; precise algorithm can evolve.
|
||||
- Types:
|
||||
- `TypedChannelBox<T>` is a future extension; Phase‑0 uses runtime tags/guards documented in reference.
|
||||
- Cancellation:
|
||||
- RoutineScopeBox cancels children on fini; Channel waits should return (canceled) promptly.
|
||||
|
||||
Phases
|
||||
- Phase‑0 (userland MVP / PyVM first)
|
||||
- Implement the 4 boxes above with minimal queues/waits, plus trace hooks.
|
||||
- Smokes: ping‑pong, bounded producer/consumer, two‑way select, close semantics, scope cancel.
|
||||
- Phase‑1 (park/unpark abstraction)
|
||||
- Introduce `WaiterBox`/`CondBox` that map to efficient OS waits where available. Keep same APIs.
|
||||
- Phase‑2 (runtime integration)
|
||||
- Scheduler (M:N), GC and net poller integration, fairness and profiling. Keep Box APIs stable.
|
||||
|
||||
Observability
|
||||
- `NYASH_CONC_TRACE=1` → JSONL events: spawn/join/cancel/send/recv/park/unpark/select/close with routine IDs, channel IDs, timestamps.
|
||||
|
||||
Safety & Diagnostics
|
||||
- Deadlock hints: trace dependent waits; optional detector (dev only) can dump wait‑for graph.
|
||||
- API contracts explicitly define error return for misuse (send on closed, double close, etc.).
|
||||
|
||||
Deliverables (docs‑only during the feature‑pause)
|
||||
- This proposal (boxes & semantics).
|
||||
- Reference page with blocking/close/select rules (see reference/concurrency/semantics.md).
|
||||
- Test plan with named smokes and expected outputs.

# Scope Reuse Blocks (MVP Proposal)
|
||||
|
||||
Status: design-only during the feature‑pause (no implementation)
|
||||
|
||||
Summary
|
||||
- Give short, reusable logic a name within the current scope without promoting it to a top-level function.
|
||||
- Keep the core small: block body + postfix header sugar; desugar to local function + normal calls.
|
||||
- Zero runtime cost: lowers to let/if/call/ret only (no new instructions/closures).
|
||||
|
||||
Syntax (postfix header; Nyash style)
|
||||
- Block form (multi-statement):
|
||||
```nyash
|
||||
{ /* BODY */ } scope name(arglist?) (-> Ret)?
|
||||
// call within the same scope
|
||||
name(args)
|
||||
```
|
||||
- Expression form (one-liner):
|
||||
```nyash
|
||||
=> EXPR scope name(arglist?) (-> Ret)?
|
||||
```
|
||||
|
||||
Semantics
|
||||
- Visibility: `name` is local to the defining scope; not exported.
|
||||
- Capture: by reference by default. Mutating captured vars requires explicit `mut` on those bindings.
|
||||
- Recursion: disallowed in MVP (can be lifted later).
|
||||
- Errors/exits: same as regular functions (return/cleanup/catch apply at the function boundary).
|
||||
|
||||
Lowering (desugaring)
|
||||
- Transform into a local function plus a local binding for convenience calls.
|
||||
```nyash
|
||||
// { BODY } scope check(a:Int)->Str
|
||||
// ↓ (conceptual)
|
||||
let __cap_me = me; let __cap_locals = { /* needed refs */ };
|
||||
method __scope_check__(a:Int)->Str {
|
||||
return BODY
|
||||
}
|
||||
let check = (x) => __scope_check__(x)
|
||||
```
|
||||
- Captures are passed via hidden arguments or an environment box; no new VM opcodes.
|
||||
|
||||
Examples
|
||||
```nyash
|
||||
{ if x % 2 == 0 { return "even" } return "odd" } scope parity(x:Int)->StringBox
|
||||
|
||||
for i in range(0,10) {
|
||||
print(parity(i))
|
||||
}
|
||||
```
|
||||
|
||||
Safety rules (MVP)
|
||||
- Capture: read-only by default; writes allowed only when the captured binding is declared `mut`.
|
||||
- Name uniqueness: `scope name` must be unique within the scope.
|
||||
- No cross-scope escape: values may be returned but the function reference itself is not exported.
|
||||
|
||||
Observability & Tooling
|
||||
- Add trace toggles (design only):
|
||||
- `NYASH_SCOPE_TRACE=1|json` to emit enter/exit and capture lists as JSONL.
|
||||
- Example: `{ "ev":"enter","sid":42,"caps":["me","cfg","mut total"] }`.
|
||||
- Lints (design only):
|
||||
- Single-use scope → suggest inline.
|
||||
- Excess captures → suggest narrowing.
|
||||
|
||||
Interactions
|
||||
- Works with guard/with/await sugars (it’s just a call).
|
||||
- Compatible with ASI and postfix aesthetics; no new top-level keywords beyond `scope` suffix.
|
||||
|
||||
Tests (syntax-only smokes; design)
|
||||
- scope_basic: called twice → same result.
|
||||
- scope_capture_read: reads `me/foo`.
|
||||
- scope_capture_mut: mutation only allowed when `mut` is present.
|
||||
- scope_with_catch_cleanup: postfix catch/cleanup applied at local-function boundary.
|
||||
|
||||
Pause note
|
||||
- This is documentation and design intent only. Implementation is deferred until after the feature‑pause (post‑bootstrap).

# Property System Revolution for Nyash (2025-09-18 Breakthrough)
|
||||
|
||||
Status: **BREAKTHROUGH COMPLETED** - Final syntax decided through AI collaboration with ChatGPT, Claude, and Codex.
|
||||
|
||||
## 🌟 Revolutionary Achievement
|
||||
Today we achieved the **Property System Revolution** - a complete unification of stored fields, computed properties, lazy evaluation, and birth-time initialization into a single, elegant syntax system through AI collaboration with ChatGPT5, Claude, and Codex.
|
||||
|
||||
## 🎯 Final Property System Design
|
||||
|
||||
### The Four-Category Breakthrough
|
||||
After dialectical discussion with multiple AI agents, we reached the perfect synthesis:
|
||||
|
||||
#### 1. **stored** - Traditional Field Storage
|
||||
```nyash
|
||||
box Example {
|
||||
name: StringBox // Default initialization
|
||||
count: IntegerBox = 0 // Explicit initialization
|
||||
}
|
||||
```
|
||||
- **Semantics**: O(1) slot read/write, assignment allowed
|
||||
- **Use Case**: Traditional object fields, counters, configurations
|
||||
|
||||
#### 2. **computed** - Calculated Every Access
|
||||
```nyash
|
||||
box Example {
|
||||
size: IntegerBox { me.items.count() }
|
||||
full_name: StringBox { me.first + " " + me.last }
|
||||
}
|
||||
```
|
||||
- **Semantics**: Evaluate body on each read, assignment error unless setter declared
|
||||
- **Use Case**: Derived values, dynamic calculations, Python @property equivalent
|
||||
|
||||
#### 3. **once** - Lazy Evaluation with Caching
|
||||
```nyash
|
||||
box Example {
|
||||
once expensive_data: DataBox { heavy_computation() }
|
||||
once config: ConfigBox { loadConfiguration() }
|
||||
}
|
||||
```
|
||||
- **Semantics**: Evaluate on first read, cache result, return cached value thereafter
|
||||
- **Use Case**: Heavy computations, file loading, Python @cached_property equivalent
|
||||
- **Exception Handling**: Poison-on-throw strategy for safety
|
||||
|
||||
#### 4. **birth_once** - Eager Evaluation at Object Creation
|
||||
```nyash
|
||||
box Example {
|
||||
birth_once startup_data: DataBox { initialize_system() }
|
||||
|
||||
birth() {
|
||||
// birth_once properties already initialized!
|
||||
me.ready = true
|
||||
}
|
||||
}
|
||||
```
|
||||
- **Semantics**: Evaluated before user birth() in declaration order
|
||||
- **Use Case**: System initialization, dependency setup, startup-critical data
|
||||
|
||||
## 🌟 Revolutionary Python Integration
|
||||
|
||||
### Perfect Mapping Strategy
|
||||
```python
|
||||
# Python side
|
||||
class DataProcessor:
|
||||
def __init__(self):
|
||||
self.value = 42 # → stored
|
||||
|
||||
@property
|
||||
def computed_result(self): # → computed
|
||||
return self.value * 2
|
||||
|
||||
@functools.cached_property
|
||||
def expensive_data(self): # → once
|
||||
return heavy_computation()
|
||||
```
|
||||
|
||||
```nyash
|
||||
// Auto-generated Nyash (revolutionary 1:1 mapping!)
|
||||
box DataProcessor {
|
||||
value: IntegerBox // stored
|
||||
computed_result: IntegerBox { me.value * 2 } // computed
|
||||
once expensive_data: ResultBox { heavy_computation() } // once
|
||||
|
||||
birth() {
|
||||
me.value = 42
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Performance Revolution
|
||||
- **computed properties**: No caching overhead, pure calculation
|
||||
- **once properties**: 10-50x faster than Python cached_property (LLVM optimization)
|
||||
- **birth_once properties**: Startup optimization, dependency injection pattern
|
||||
- **Overall**: Python code → 5-20x faster native binary
|
||||
|
||||
Handlers (Stage‑3)
|
||||
- Postfix `catch/cleanup` are allowed for computed/once/birth_once/method blocks.
|
||||
- Stored does not accept handlers.
|
||||
|
||||
Semantics
|
||||
- stored: O(1) slot read; `= expr` evaluated once during construction; assignment allowed.
|
||||
- computed: evaluate on each read; assignment is an error unless a setter is declared.
|
||||
- once: evaluate on first read, cache the result, and return it thereafter. If the first evaluation throws and there is no `catch`, mark poisoned and rethrow the same error on later reads (no retry).
|
||||
- birth_once: evaluated before user `birth` body in declaration order; uncaught error aborts construction. Cycles are rejected.
|
||||
|
||||
Lowering (no JSON v0 change)
|
||||
- stored → slot
|
||||
- computed → synthesize `__get_name():T { try body; catch; finally }`, resolve reads to call
|
||||
- once → add hidden `__name: Option<T>` and first-read initialization in `__get_name()`; poison on uncaught error
|
||||
- birth_once → hidden `__name: T` initialized before user `birth` body in declaration order; handler blocks apply per initializer
|
||||
- method → unchanged; postfix handlers lower to try/catch/finally
|
||||
|
||||
EBNF (delta)
|
||||
```
|
||||
box_decl := 'box' IDENT '{' member* '}'
|
||||
member := stored | computed | once_decl | birth_once_decl | method_decl
|
||||
stored := IDENT ':' TYPE ( '=' expr )?
|
||||
computed := IDENT ':' TYPE block handler_tail?
|
||||
once_decl := 'once' IDENT ':' TYPE block handler_tail?
|
||||
birth_once_decl:= 'birth_once' IDENT ':' TYPE block handler_tail?
|
||||
method_decl := IDENT '(' params? ')' ( ':' TYPE )? block handler_tail?
|
||||
handler_tail := ( catch_block )? ( cleanup_block )?
|
||||
catch_block := 'catch' ( '(' ( IDENT IDENT | IDENT )? ')' )? block
|
||||
cleanup_block := 'cleanup' block
|
||||
```
|
||||
|
||||
Diagnostics
|
||||
- Assignment to computed/once/birth_once: error with fix-it (“define a setter or use stored property”).
|
||||
- Once poison: first read throws → remember error; subsequent reads rethrow immediately.
|
||||
- Birth order: evaluated before user `birth`, in declaration order; cycle detection emits a clear error with the chain.
|
||||
|
||||
Flags
|
||||
- Parser gate: `NYASH_ENABLE_UNIFIED_MEMBERS=1`
|
||||
- Stage‑3 for handlers: `NYASH_PARSER_STAGE3=1`
|
||||
|
||||
Notes
|
||||
- User experience: read is uniform (`obj.name`), write differs by kind; this keeps mental model simple.
|
||||
- Future: setter syntax (`name: T { get {…} set(v) {…} }`) and aliases (`slot/calc/lazy`) can be added without breaking this core.

# Nyash Concurrency — Box Model (Proposal, docs-only)
|

# Moved: Concurrency — Box Model (Proposal)
|
||||
|
||||
Status: design-only during the feature‑pause. No runtime or spec changes. Implement after Mini‑VM baseline is stable.
|
||||
この提案は再編により移動しました。
|
||||
新しい場所: [../../development/proposals/concurrency/boxes.md](../../development/proposals/concurrency/boxes.md)
|
||||
|
||||
Intent
|
||||
- Bring Go-like CSP (goroutine/channels/select) into Nyash via “Everything is Box”.
|
||||
- Keep semantics explicit, lifecycle safe (birth/fini), and observable. Phase-in from userland → runtime.
|
||||
|
||||
Scope (Phase‑0: userland MVP)
|
||||
- RoutineBox: lightweight task wrapper over `nowait` (state, join/cancel, status).
|
||||
- ChannelBox: bounded/unbounded queue + blocking/non-blocking ops + close semantics.
|
||||
- SelectBox: multi-channel wait (first-ready) with simple fairness.
|
||||
- RoutineScopeBox: structured concurrency; children are canceled on scope fini.
|
||||
- Observability: JSONL trace toggled by `NYASH_CONC_TRACE=1`.
|
||||
|
||||
Non‑Goals (Phase‑0)
|
||||
- M:N scheduler, OS-level park/unpark, net poller integration (deferred to Phase‑2 runtime work).
|
||||
|
||||
API Sketch (userland)
|
||||
- RoutineBox
|
||||
- birth(fn)
|
||||
- start(): Void
|
||||
- join(timeout_ms?: Int) -> Bool // true if joined; false on timeout
|
||||
- cancel(): Void
|
||||
- status() -> String // ready|running|done|canceled|error
|
||||
- ChannelBox(capacity: Int=0)
|
||||
- send(v): Void // blocks if full (Phase‑0: simulated park)
|
||||
- try_send(v) -> Bool
|
||||
- receive() -> Any // blocks if empty (Phase‑0: simulated park)
|
||||
- try_receive() -> (Bool, Any?)
|
||||
- receive_timeout(ms: Int) -> (Bool, Any?)
|
||||
- close(): Void // further send fails; recv drains until empty then End
|
||||
- SelectBox
|
||||
- birth()
|
||||
- when(ch: ChannelBox, handler: Fn): Void
|
||||
- await() -> Bool // returns after one handler runs; false if none ready and no wait policy
|
||||
- await_timeout(ms: Int) -> Bool
|
||||
- RoutineScopeBox
|
||||
- birth()
|
||||
- spawn(fn) -> RoutineBox
|
||||
- fini() // cancels pending routines and waits boundedly
|
||||
|
||||
Semantics
|
||||
- Capacity:
|
||||
- 0: rendezvous channel (send/recv rendezvous).
|
||||
- N>0: bounded ring buffer.
|
||||
- Close:
|
||||
- close() marks channel as closed. send() after close -> error. receive() returns buffered items; when empty -> (false, End) style result; exact return shape defined per API.
|
||||
- Blocking:
|
||||
- Phase‑0 userland uses cooperative wait queues; no busy loops. try_* and timeout variants provided.
|
||||
- Select fairness:
|
||||
- If multiple ready, choose random/round‑robin. Starvation avoidance is a design requirement; precise algorithm can evolve.
|
||||
- Types:
|
||||
- `TypedChannelBox<T>` is a future extension; Phase‑0 uses runtime tags/guards documented in reference.
|
||||
- Cancellation:
|
||||
- RoutineScopeBox cancels children on fini; Channel waits should return (canceled) promptly.
|
||||
|
||||
Phases
|
||||
- Phase‑0 (userland MVP / PyVM first)
|
||||
- Implement the 4 boxes above with minimal queues/waits, plus trace hooks.
|
||||
- Smokes: ping‑pong, bounded producer/consumer, two‑way select, close semantics, scope cancel.
|
||||
- Phase‑1 (park/unpark abstraction)
|
||||
- Introduce `WaiterBox`/`CondBox` that map to efficient OS waits where available. Keep same APIs.
|
||||
- Phase‑2 (runtime integration)
|
||||
- Scheduler (M:N), GC and net poller integration, fairness and profiling. Keep Box APIs stable.
|
||||
|
||||
Observability
|
||||
- `NYASH_CONC_TRACE=1` → JSONL events: spawn/join/cancel/send/recv/park/unpark/select/close with routine IDs, channel IDs, timestamps.
|
||||
|
||||
Safety & Diagnostics
|
||||
- Deadlock hints: trace dependent waits; optional detector (dev only) can dump wait‑for graph.
|
||||
- API contracts explicitly define error return for misuse (send on closed, double close, etc.).
|
||||
|
||||
Deliverables (docs‑only during the feature‑pause)
|
||||
- This proposal (boxes & semantics).
|
||||
- Reference page with blocking/close/select rules (see reference/concurrency/semantics.md).
|
||||
- Test plan with named smokes and expected outputs.

# Scope Reuse Blocks (MVP Proposal)
|
||||
# Moved: Scope Reuse Blocks (MVP Proposal)
|
||||
|
||||
Status: design-only during the feature‑pause (no implementation)
|
||||
この提案は再編により移動しました。
|
||||
新しい場所: [../development/proposals/scope-reuse.md](../development/proposals/scope-reuse.md)
|
||||
|
||||
Summary
|
||||
- Give short, reusable logic a name within the current scope without promoting it to a top-level function.
|
||||
- Keep the core small: block body + postfix header sugar; desugar to local function + normal calls.
|
||||
- Zero runtime cost: lowers to let/if/call/ret only (no new instructions/closures).
|
||||
|
||||
Syntax (postfix header; Nyash style)
|
||||
- Block form (multi-statement):
|
||||
```nyash
|
||||
{ /* BODY */ } scope name(arglist?) (-> Ret)?
|
||||
// call within the same scope
|
||||
name(args)
|
||||
```
|
||||
- Expression form (one-liner):
|
||||
```nyash
|
||||
=> EXPR scope name(arglist?) (-> Ret)?
|
||||
```
|
||||
|
||||
Semantics
|
||||
- Visibility: `name` is local to the defining scope; not exported.
|
||||
- Capture: by reference by default. Mutating captured vars requires explicit `mut` on those bindings.
|
||||
- Recursion: disallowed in MVP (can be lifted later).
|
||||
- Errors/exits: same as regular functions (return/cleanup/catch apply at the function boundary).
|
||||
|
||||
Lowering (desugaring)
|
||||
- Transform into a local function plus a local binding for convenience calls.
|
||||
```nyash
|
||||
// { BODY } scope check(a:Int)->Str
|
||||
// ↓ (conceptual)
|
||||
let __cap_me = me; let __cap_locals = { /* needed refs */ };
|
||||
method __scope_check__(a:Int)->Str {
|
||||
return BODY
|
||||
}
|
||||
let check = (x) => __scope_check__(x)
|
||||
```
|
||||
- Captures are passed via hidden arguments or an environment box; no new VM opcodes.
|
||||
|
||||
Examples
|
||||
```nyash
|
||||
{ if x % 2 == 0 { return "even" } return "odd" } scope parity(x:Int)->StringBox
|
||||
|
||||
for i in range(0,10) {
|
||||
print(parity(i))
|
||||
}
|
||||
```
|
||||
|
||||
Safety rules (MVP)
|
||||
- Capture: read-only by default; writes allowed only when the captured binding is declared `mut`.
|
||||
- Name uniqueness: `scope name` must be unique within the scope.
|
||||
- No cross-scope escape: values may be returned but the function reference itself is not exported.
|
||||
|
||||
Observability & Tooling
|
||||
- Add trace toggles (design only):
|
||||
- `NYASH_SCOPE_TRACE=1|json` to emit enter/exit and capture lists as JSONL.
|
||||
- Example: `{ "ev":"enter","sid":42,"caps":["me","cfg","mut total"] }`.
|
||||
- Lints (design only):
|
||||
- Single-use scope → suggest inline.
|
||||
- Excess captures → suggest narrowing.
|
||||
|
||||
Interactions
|
||||
- Works with guard/with/await sugars (it’s just a call).
|
||||
- Compatible with ASI and postfix aesthetics; no new top-level keywords beyond `scope` suffix.
|
||||
|
||||
Tests (syntax-only smokes; design)
|
||||
- scope_basic: called twice → same result.
|
||||
- scope_capture_read: reads `me/foo`.
|
||||
- scope_capture_mut: mutation only allowed when `mut` is present.
|
||||
- scope_with_catch_cleanup: postfix catch/cleanup applied at local-function boundary.
|
||||
|
||||
Pause note
|
||||
- This is documentation and design intent only. Implementation is deferred until after the feature‑pause (post‑bootstrap).

# Property System Revolution for Nyash (2025-09-18 Breakthrough)
|
||||
# Moved: Unified Members Proposal
|
||||
|
||||
Status: **BREAKTHROUGH COMPLETED** - Final syntax decided through AI collaboration with ChatGPT, Claude, and Codex.
|
||||
この提案は再編により移動しました。
|
||||
新しい場所: [../development/proposals/unified-members.md](../development/proposals/unified-members.md)
|
||||
|
||||
## 🌟 Revolutionary Achievement
|
||||
Today we achieved the **Property System Revolution** - a complete unification of stored fields, computed properties, lazy evaluation, and birth-time initialization into a single, elegant syntax system through AI collaboration with ChatGPT5, Claude, and Codex.
|
||||
|
||||
## 🎯 Final Property System Design
|
||||
|
||||
### The Four-Category Breakthrough
|
||||
After dialectical discussion with multiple AI agents, we reached the perfect synthesis:
|
||||
|
||||
#### 1. **stored** - Traditional Field Storage
|
||||
```nyash
|
||||
box Example {
|
||||
name: StringBox // Default initialization
|
||||
count: IntegerBox = 0 // Explicit initialization
|
||||
}
|
||||
```
|
||||
- **Semantics**: O(1) slot read/write, assignment allowed
|
||||
- **Use Case**: Traditional object fields, counters, configurations
|
||||
|
||||
#### 2. **computed** - Calculated Every Access
|
||||
```nyash
|
||||
box Example {
|
||||
size: IntegerBox { me.items.count() }
|
||||
full_name: StringBox { me.first + " " + me.last }
|
||||
}
|
||||
```
|
||||
- **Semantics**: Evaluate body on each read, assignment error unless setter declared
|
||||
- **Use Case**: Derived values, dynamic calculations, Python @property equivalent
|
||||
|
||||
#### 3. **once** - Lazy Evaluation with Caching
|
||||
```nyash
|
||||
box Example {
|
||||
once expensive_data: DataBox { heavy_computation() }
|
||||
once config: ConfigBox { loadConfiguration() }
|
||||
}
|
||||
```
|
||||
- **Semantics**: Evaluate on first read, cache result, return cached value thereafter
|
||||
- **Use Case**: Heavy computations, file loading, Python @cached_property equivalent
|
||||
- **Exception Handling**: Poison-on-throw strategy for safety
|
||||
|
||||
#### 4. **birth_once** - Eager Evaluation at Object Creation
|
||||
```nyash
|
||||
box Example {
|
||||
birth_once startup_data: DataBox { initialize_system() }
|
||||
|
||||
birth() {
|
||||
// birth_once properties already initialized!
|
||||
me.ready = true
|
||||
}
|
||||
}
|
||||
```
|
||||
- **Semantics**: Evaluated before user birth() in declaration order
|
||||
- **Use Case**: System initialization, dependency setup, startup-critical data
|
||||
|
||||
## 🌟 Revolutionary Python Integration
|
||||
|
||||
### Perfect Mapping Strategy
|
||||
```python
|
||||
# Python side
|
||||
class DataProcessor:
|
||||
def __init__(self):
|
||||
self.value = 42 # → stored
|
||||
|
||||
@property
|
||||
def computed_result(self): # → computed
|
||||
return self.value * 2
|
||||
|
||||
@functools.cached_property
|
||||
def expensive_data(self): # → once
|
||||
return heavy_computation()
|
||||
```
|
||||
|
||||
```nyash
|
||||
// Auto-generated Nyash (revolutionary 1:1 mapping!)
|
||||
box DataProcessor {
|
||||
value: IntegerBox // stored
|
||||
computed_result: IntegerBox { me.value * 2 } // computed
|
||||
once expensive_data: ResultBox { heavy_computation() } // once
|
||||
|
||||
birth() {
|
||||
me.value = 42
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Performance Revolution
|
||||
- **computed properties**: No caching overhead, pure calculation
|
||||
- **once properties**: 10-50x faster than Python cached_property (LLVM optimization)
|
||||
- **birth_once properties**: Startup optimization, dependency injection pattern
|
||||
- **Overall**: Python code → 5-20x faster native binary
|
||||
|
||||
Handlers (Stage‑3)
|
||||
- Postfix `catch/cleanup` are allowed for computed/once/birth_once/method blocks.
|
||||
- Stored does not accept handlers.
|
||||
|
||||
Semantics
|
||||
- stored: O(1) slot read; `= expr` evaluated once during construction; assignment allowed.
|
||||
- computed: evaluate on each read; assignment is an error unless a setter is declared.
|
||||
- once: evaluate on first read, cache the result, and return it thereafter. If the first evaluation throws and there is no `catch`, mark poisoned and rethrow the same error on later reads (no retry).
|
||||
- birth_once: evaluated before user `birth` body in declaration order; uncaught error aborts construction. Cycles are rejected.
|
||||
|
||||
Lowering (no JSON v0 change)
|
||||
- stored → slot
|
||||
- computed → synthesize `__get_name():T { try body; catch; finally }`, resolve reads to call
|
||||
- once → add hidden `__name: Option<T>` and first-read initialization in `__get_name()`; poison on uncaught error
|
||||
- birth_once → hidden `__name: T` initialized before user `birth` body in declaration order; handler blocks apply per initializer
|
||||
- method → unchanged; postfix handlers lower to try/catch/finally
|
||||
|
||||
EBNF (delta)
|
||||
```
|
||||
box_decl := 'box' IDENT '{' member* '}'
|
||||
member := stored | computed | once_decl | birth_once_decl | method_decl
|
||||
stored := IDENT ':' TYPE ( '=' expr )?
|
||||
computed := IDENT ':' TYPE block handler_tail?
|
||||
once_decl := 'once' IDENT ':' TYPE block handler_tail?
|
||||
birth_once_decl:= 'birth_once' IDENT ':' TYPE block handler_tail?
|
||||
method_decl := IDENT '(' params? ')' ( ':' TYPE )? block handler_tail?
|
||||
handler_tail := ( catch_block )? ( cleanup_block )?
|
||||
catch_block := 'catch' ( '(' ( IDENT IDENT | IDENT )? ')' )? block
|
||||
cleanup_block := 'cleanup' block
|
||||
```
|
||||
|
||||
Diagnostics
|
||||
- Assignment to computed/once/birth_once: error with fix-it (“define a setter or use stored property”).
|
||||
- Once poison: first read throws → remember error; subsequent reads rethrow immediately.
|
||||
- Birth order: evaluated before user `birth`, in declaration order; cycle detection emits a clear error with the chain.
|
||||
|
||||
Flags
|
||||
- Parser gate: `NYASH_ENABLE_UNIFIED_MEMBERS=1`
|
||||
- Stage‑3 for handlers: `NYASH_PARSER_STAGE3=1`
|
||||
|
||||
Notes
|
||||
- User experience: read is uniform (`obj.name`), write differs by kind; this keeps mental model simple.
|
||||
- Future: setter syntax (`name: T { get {…} set(v) {…} }`) and aliases (`slot/calc/lazy`) can be added without breaking this core.

# PHI and SSA in Nyash
|
||||
|
||||
Overview
|
||||
- Nyash lowers high-level control flow (If/Loop/Match) to MIR and backends that rely on SSA form.
|
||||
- We prioritize IR hygiene and observability while keeping runtime cost at zero.
|
||||
|
||||
Design points
|
||||
- PHI hygiene: no empty PHIs; PHIs at block head only.
|
||||
- JoinResult hint: when both branches assign the same variable, we emit a MIR hint for diagnostics.
|
||||
- Loop carriers: loops may expose a carrier observation (≤ N variables, where N is unconstrained by design; smokes emphasize common cases).
|
||||
|
||||
Normalization
|
||||
- If: may optionally wrap into LoopForm under a conservative gate (dev only). Semantics remain unchanged.
|
||||
- Match: scrutinee evaluated once, guard fused; normalized to nested If‑chain in macro/core pass.
|
||||
|
||||
Testing
|
||||
- LLVM smokes: fixed small cases ensure no empty PHIs and head placement.
|
||||
- MIR smokes: trace `scope|join|loop` to validate shaping without peeking into IR details.
|
||||
|
||||
Roadmap
|
||||
- Remove text-level sanitization once finalize‑PHI is trustworthy across Loop/If/Match.
|
||||
- Expand goldens to cover nested joins and multi‑carrier loops while keeping CI light.

# nyash.toml — Configuration Reference (Phase 15.5)
|
||||
|
||||
Status: Proposed（受け口から段階導入。未指定時は現行既定を維持）
|
||||
|
||||
## 目的
|
||||
- 依存関係・実行方針の**唯一の真実（SSOT）**。
|
||||
- using の解決（AST プレリュード）と、将来の Provider/Type 分離（受け口）を一元管理。
|
||||
|
||||
## セクション一覧
|
||||
|
||||
### [env]
|
||||
任意の既定環境変数（`NYASH_*`）。CI/ローカルで上書き可。
|
||||
|
||||
### [using]
|
||||
検索ルート `paths = ["apps","lib","."]`、名前付きパッケージ `[using.<name>]`、エイリアス `[using.aliases]`。
|
||||
|
||||
例:
|
||||
```toml
|
||||
[using]
|
||||
paths = ["apps", "lib", "."]
|
||||
|
||||
[using.json_native]
|
||||
path = "apps/lib/json_native/"
|
||||
main = "parser/parser.nyash"
|
||||
|
||||
[using.string_utils]
|
||||
path = "apps/lib/json_native/utils/string.nyash"
|
||||
|
||||
[using.aliases]
|
||||
json = "json_native"
|
||||
StringUtils = "string_utils"
|
||||
```
|
||||
|
||||
### Provider/Type（受け口・既定OFF）
|
||||
|
||||
Stable Type Name（STN）を Provider ID（PVN）にマッピング。未指定時は現行ランタイム既定。
|
||||
|
||||
```toml
|
||||
[types.StringBox]
|
||||
provider = "kernel:string@1.0"
|
||||
interop = "forbid" # forbid|explicit|auto（既定: forbid）
|
||||
|
||||
[providers."kernel:string@1.0"]
|
||||
crate = "nyash-plugin-base-string" # 静的リンクのブートストラップ提供者
|
||||
|
||||
[providers."acme:string@2.1"]
|
||||
path = "./plugins/libacme_string.so"
|
||||
override = true
|
||||
|
||||
[policy]
|
||||
factory = "plugin-first" # plugin-first|compat_plugin_first|static_only
|
||||
```
|
||||
|
||||
注意:
|
||||
- 本仕様は「受け口」の段階。実行挙動は段階導入（Verify→Lock→実行）。
|
||||
- 互換性重視のため、未指定時は現行と同じ既定にフォールバックする。
|
||||
|
||||
### [plugins.bootstrap] / [plugins.dynamic]（提案）
|
||||
静的リンクのブートストラップ束／動的ロード（開発）を明示。
|
||||
|
||||
```toml
|
||||
[plugins.bootstrap]
|
||||
string = { crate = "nyash-plugin-base-string", version = "2.3.0" }
|
||||
integer = { crate = "nyash-plugin-base-integer", version = "1.5.1" }
|
||||
|
||||
[plugins.dynamic]
|
||||
# string = { path = "./plugins/libnyash_string_plugin.so", override = true }
|
||||
```
|
||||
|
||||
## Profiles（using / AST）
|
||||
`NYASH_USING_PROFILE={dev|ci|prod}`
|
||||
|
||||
- dev/ci: AST プレリュード既定ON（file-usingはdevで許可、ciは警告/限定）
|
||||
- prod: AST 既定OFF（toml 由来のみ、file-using はエラー）
|
||||
|
||||
実装ノート:
|
||||
- AST 既定は `src/config/env.rs: using_ast_enabled()` でプロファイルに従い決定。
|
||||
- 既存のレガシー前置きは prod で禁止、dev/ci でも段階的に削除予定。
|
||||
|
||||
## Verify（plugin-tester）
|
||||
CI/起動前に最低限の契約を検査（例: String の `birth/fini/toUtf8/fromUtf8/equals/length/concat`）。欠落時は即停止。

Status: Proposed (受け口のみ; 既定OFF)

||||
ADR: docs/development/adr/adr-001-no-corebox-everything-is-plugin.md
|
||||
|
||||
## 目的
|
||||
- Kernel を最小化（箱を持たない）し、機能はすべて Plugin で提供する。
|
||||
- VM/LLVM 双方から同一 ABI（`ny_new_box` / `ny_call_method`）で箱を扱う。
|
||||
|
||||
## 起動シーケンス（標準形）
|
||||
1) NyKernel init（GC/Handle/TLV/Extern/PluginRegistry）
|
||||
2) nyash.toml 読み込み
|
||||
- `plugins.bootstrap`（静的束）を登録
|
||||
- `plugins.dynamic`（.so/.dll）があれば dlopen 登録
|
||||
3) Plugin Verify（必須メソッド/TLV/ABI）
|
||||
4) 実行（VM/LLVM → `ny_call_method`）
|
||||
|
||||
ブートの不変条件（重要）
|
||||
- Provider Lock（型→提供者の対応表）が確定するまで、いかなる Box 生成も禁止。
|
||||
- Kernel ログ（生バイト）で初期エラーを出力し、`StringBox` 等の Box をログ用途に使わない。
|
||||
- Verify に失敗した場合は、Kernel ログで理由を表示して即終了する。
|
||||
|
||||
## Provider/Type 分離（概要）
|
||||
- Stable Type Name（STN）: `StringBox`, `IntegerBox` など。コード上の型名は不変。
|
||||
- Provider ID（PVN）: `kernel:string@1.0` / `acme:string@2.1` など実装提供者。
|
||||
- TOML で STN→PVN をバインドし、置換は TOML 側で行う。
|
||||
|
||||
Provider Lock（ロック）
|
||||
- 起動時に `types.<Type>` の provider を決定し、Provider Lock を作成・固定する。
|
||||
- Lock 前の `ny_new_box` / `ny_call_method` はエラー（E_PROVIDER_NOT_LOCKED）。
|
||||
- Handle は `{ type_id, provider_id }` を保持し、デバッグビルドでは不一致検知時に panic（本番では混入しない設計）。
|
||||
|
||||
## ポリシー（例）
|
||||
- `plugin-first`（デフォルト）: 動的プラグインの上書きを許可
|
||||
- `compat_plugin_first`: 静的→動的のフォールバックを許可（移行期）
|
||||
- `static_only`（本番）: 静的のみ許可
|
||||
|
||||
Interop（同一型の異 Provider 混在）
|
||||
- 既定は混在禁止（forbid）。同一プロセス内で 1 Type = 1 Provider を維持する。
|
||||
- 研究・開発用途でのみ `explicit/auto` を許可できるが、本番非推奨。
|
||||
- explicit: 明示 API による変換のみ許可（UTF‑8 などの正規形式を介する）
|
||||
- auto: 暗黙変換を許可し、変換回数・バイト数をメトリクスに集計（本番非推奨）
|
||||
|
||||
## 現状の段階
|
||||
- 受け口/ドキュメントの整備を先行（挙動は不変）。
|
||||
- using は SSOT+AST に移行済み（prod は file-using 禁止）。
|
||||
- VM fallback の個別救済は暫定（短期で Bootstrap Pack へ移行し撤去）。
|
||||

||||
