🚀 feat: Multiple improvements for Nyash parser and LLVM backend
Parser improvements: - Added expression statement fallback in parse_statement() for flexible syntax - Fixed ternary operator to use PeekExpr instead of If AST (better lowering) - Added peek_token() check to avoid ?/?: operator conflicts LLVM Python improvements: - Added optional ESC_JSON_FIX environment flag for string concatenation - Improved PHI generation with better default handling - Enhanced substring tracking for esc_json pattern Documentation updates: - Updated language guide with peek expression examples - Added box theory diagrams to Phase 15 planning - Clarified peek vs when syntax differences These changes enable cleaner parser implementation for self-hosting, especially for handling digit conversion with peek expressions instead of 19-line if-else chains. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Summary
|
||||
- JIT/Cranelift は一時停止。Rust/inkwell LLVM は参照のみ。
|
||||
- 既定の実行/ビルド経路は Python/llvmlite ハーネス（MIR JSON→.o→NyRT link）。
|
||||
- 2本目の実行経路として PyVM（Python MIR VM）を導入し、llvmlite との機能同値で安定化する。
|
||||
- A6 受入（parity+verify）を達成済み。次は Nyash パーサMVP 着手。
|
||||
|
||||
Quick Status — 2025‑09‑13（post‑harness hardening）
|
||||
- llvmlite（ハーネス）で verify green → .o → link が代表ケースで成立（dep_tree_min_string）
|
||||
- Resolver‑only/Sealed SSA/文字列ハンドル不変を強化。PHIはBB先頭・pred終端でboxing/cast。
|
||||
- IRダンプ/PHIガード/deny-directチェックが利用可能（NYASH_LLVM_DUMP_IR, NYASH_LLVM_PHI_STRICT, tools/llvmlite_check_deny_direct.sh）。
|
||||
Quick Status — 2025‑09‑14（A6 Accepted）
|
||||
- esc_dirname_smoke: PyVM↔llvmlite パリティ一致（ゲートOFF）。
|
||||
- dep_tree_min_string: PyVM↔llvmlite パリティ一致。llvmlite 経路で `.ll verify → .o → EXE` 完走。
|
||||
- 一時救済ゲート `NYASH_LLVM_ESC_JSON_FIX` は受入では未使用（OFF）。
|
||||
- Resolver‑only/Sealed SSA/文字列ハンドル不変は継続運用。IRダンプ/PHIガード/deny-direct チェック利用可。
|
||||
|
||||
Focus Shift — llvmlite（既定）+ PyVM（新規）
|
||||
- Rust/inkwell は保守のみ。Python（llvmlite/PyVM）中心で開発。
|
||||
@ -33,12 +35,11 @@ Hot Update — 2025‑09‑13（Resolver‑only 統一 + Harness ON green）
|
||||
- `main` 衝突回避: MIR 由来 `main` は private にし、`ny_main()` ラッパを自動生成（NyRT `main` と整合）。
|
||||
- 代表ケース（dep_tree_min_string）: Harness ON で `.ll verify green → .o` を確認し、NyRT とリンクして EXE 生成成功。
|
||||
|
||||
Next（short — Py/llvmlite + PyVM）
|
||||
1) PyVM スキャフォールド: `tools/pyvm_runner.py` と `src/llvm_py/pyvm/` 追加（最小命令+boxcall）。
|
||||
2) ランナー統合: `NYASH_VM_USE_PY=1` → MIR(JSON) を PyVM に渡して実行。
|
||||
3) パリティ基盤: 汎用パリティスクリプト `tools/parity.sh` を追加（stdout+exit code 比較、pyvm/vm/llvmlite 任意ペア）。
|
||||
4) 型メタ導入（MIR v0.5 互換）: JSON MIR に String の handle/ptr 種別を明示し、llvmlite/PyVM で推測を排除。
|
||||
5) スモーク拡充: esc_dirname_smoke / dep_tree_min_string の両経路一致（終了コード+JSON）。
|
||||
Next（short — Parser MVP kick‑off）
|
||||
1) Ny→JSON v0 パイプを Nyash で実装（整数/文字列/四則/括弧/return）。
|
||||
2) `--ny-parser-pipe`/`--json-file` と互換の JSON v0 を出力し、既存ブリッジで実行。
|
||||
3) スモーク: `tools/ny_roundtrip_smoke.sh` 緑、`esc_dirname_smoke`/`dep_tree_min_string` を Ny パーサ経路で PyVM/llvmlite とパリティ一致。
|
||||
4) （続）Ny AST→MIR JSON 直接降下の設計（箱構造/型メタ連携）。
|
||||
|
||||
Hot Update — MIR v0.5 Type Metadata（2025‑09‑14 着手）
|
||||
- 背景: 文字列を i64 として曖昧に扱っており、llvmlite で handle/ptr の推測が必要→不安定の温床。
|
||||
@ -55,6 +56,30 @@ Hot Update — MIR v0.5 Type Metadata（2025‑09‑14 着手）
|
||||
- Python 側で `dst_type` により string ハンドルのタグ付けが行われること
|
||||
- `tools/parity.sh` が esc_dirname_smoke で実行できること（完全一致は第二段で目標）
|
||||
|
||||
Hot Update — 2025‑09‑14（Option A: A6 受入完了）
|
||||
- 方針: mem2reg は採らず、MIR→JSON→llvmlite で収束。
|
||||
- 実施: if/loop の MIR 補強（then/else 再代入のPhi化、latch→header seal の堅牢化）。
|
||||
- 結果: esc_dirname_smoke / min_str_cat_loop / dep_tree_min_string が PyVM↔llvmlite で一致。LLVM verifier green → .o 成立。
|
||||
|
||||
Tasks（短期・優先順 — ParserMVP）
|
||||
1) Parser v0（Ny→JSON v0）
|
||||
- `apps/selfhost/parser/` に LexerBox/ParserBox を配置し、整数/文字列/四則/括弧/return をJSON v0に吐く。
|
||||
2) CLI/ブリッジ動線
|
||||
- `nyash --ny-parser-pipe` と同等フォーマットで出力→既存 `json_v0_bridge` で実行。
|
||||
3) スモーク整備
|
||||
- `tools/ny_roundtrip_smoke.sh`/`tools/ny_parser_bridge_smoke.sh` を Ny パーサ経路でも緑に。
|
||||
4) 設計
|
||||
- Ny AST→MIR JSON 直接降下の箱設計（型メタ/Resolverフック）。
|
||||
|
||||
Notes（ゲート/保護）
|
||||
- 進行中のみの一時救済ゲート: `NYASH_LLVM_ESC_JSON_FIX=1`
|
||||
- finalize_phis で esc_json のデフォルト枝に `out = concat(out, substring)` を pred末端に合成（dominance-safe）
|
||||
- 本命の MIR 修正が入ったため、受け入れには使用しない（OFF）。
|
||||
|
||||
Back‑up Plan（実験レーン・必要時）
|
||||
- Python MIR Builder（AST→MIR を Python で生成）を `NYASH_MIR_PYBUILDER=1` のフラグで限定導入し、smoke 2本（min_str/esc_dirname）で PyVM/llvmlite 一致を先に確保。
|
||||
- 良好なら段階移行。ダメなら即OFF（現行MIRを維持）。
|
||||
|
||||
Hot Update — 2025‑09‑14（typed binop/compare/phi + PHI on‑demand）
|
||||
- 目的: LLVM層での型推測を廃止し、MIR→JSONの型メタにもとづく機械的降下へ移行。
|
||||
- JSONエミッタ（src/runner/mir_json_emit.rs）

**最終更新: 2025年8月12日 - Phase 1完了, P2P実装準備完了**
|
||||
Start here to learn Nyash language basics and find deeper references.
|
||||
|
||||
## 📖 概要
|
||||
- Syntax Cheat Sheet: quick-reference/syntax-cheatsheet.md
|
||||
- Full Language Reference (2025): reference/language/LANGUAGE_REFERENCE_2025.md
|
||||
- Phase 12.7 Grammar (peek / ternary / sugar):
|
||||
- Overview: development/roadmap/phases/phase-12.7/grammar-specs/README.md
|
||||
- Tokens & Grammar: development/roadmap/phases/phase-12.7/ancp-specs/ANCP-Token-Specification-v1.md

|
||||
|
||||
Nyashは「Everything is Box」哲学に基づく革新的なプログラミング言語です。
|
||||
Rust製インタープリターによる高性能実行と、直感的な構文により、学習しやすく実用的な言語として完成しました。
|
||||
Common Constructs
|
||||
- Ternary operator: `cond ? then : else` (Phase 12.7); lowered to If-expression
|
||||
- Peek expression: `peek value { lit => expr, else => expr }`
|
||||
- Null-coalesce: `x ?? y` → `peek x { null => y, else => x }`
|
||||
- Safe access: `a?.b` → `peek a { null => null, else => a.b }`
|
||||
|
||||
## 🎯 核心哲学: "Everything is Box"
|
||||
|
||||
```nyash
|
||||
# すべてのデータがBoxとして統一的に表現される
|
||||
number = 42 # IntegerBox
|
||||
text = "hello" # StringBox
|
||||
flag = true # BoolBox
|
||||
array = new ArrayBox() # ArrayBox
|
||||
debug = new DebugBox() # DebugBox
|
||||
```
|
||||
|
||||
**重要な利点:**
|
||||
- **統一性**: すべてのデータが共通インターフェース
|
||||
- **メモリ安全性**: Arc<Mutex>パターンで完全スレッドセーフ
|
||||
- **拡張性**: 新しいBox型を容易に追加可能

## 🔤 言語構文リファレンス
|
||||
|
||||
### 🏷️ **変数宣言・スコープ**
|
||||
|
||||
```nyash
|
||||
// ローカル変数宣言
|
||||
local x, y
|
||||
local name = "Alice"
|
||||
|
||||
// 所有権移転変数（関数戻り値用）
|
||||
outbox result = compute()
|
||||
|
||||
// グローバル変数
|
||||
global CONFIG = "dev"
|
||||
```
|
||||
|
||||
### 🧮 **演算子**
|
||||
|
||||
```nyash
|
||||
// 算術演算子
|
||||
a + b, a - b, a * b, a / b
|
||||
|
||||
// 比較演算子
|
||||
a == b, a != b, a < b, a > b, a <= b, a >= b
|
||||
|
||||
// 論理演算子
|
||||
not condition, a and b, a or b
|
||||
|
||||
// ビット演算子（整数限定）
|
||||
a & b, a | b, a ^ b
|
||||
a << n, a >> n # 注意: 旧来の >>（ARROW）は廃止。パイプラインは |>
|
||||
|
||||
// Cross-type演算 (Phase 1で完全実装)
|
||||
10 + 3.14 // → 13.14 (型変換)
|
||||
"Value: " + 42 // → "Value: 42" (文字列連結)
|
||||
```
|
||||
|
||||
### 🏗️ **Box定義・デリゲーション**
|
||||
|
||||
#### 基本Box定義
|
||||
```nyash
|
||||
box User {
|
||||
init { name, email } // フィールド宣言
|
||||
|
||||
birth(userName, userEmail) { // 🌟 生命をBoxに与える！
|
||||
me.name = userName
|
||||
me.email = userEmail
|
||||
print("🌟 " + userName + " が誕生しました！")
|
||||
}
|
||||
|
||||
greet() {
|
||||
print("Hello, " + me.name)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### デリゲーション (2025-08 革命)
|
||||
```nyash
|
||||
box AdminUser from User { // 🔥 from構文でデリゲーション
|
||||
init { permissions }
|
||||
|
||||
birth(adminName, adminEmail, perms) {
|
||||
from User.birth(adminName, adminEmail) // 親のbirth呼び出し
|
||||
me.permissions = perms
|
||||
}
|
||||
|
||||
override greet() { // 明示的オーバーライド
|
||||
from User.greet() // 親メソッド呼び出し
|
||||
print("Admin privileges: " + me.permissions)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### ビルトインBox継承（pack専用）
|
||||
```nyash
|
||||
// ⚠️ pack構文はビルトインBox継承専用
|
||||
box EnhancedP2P from P2PBox {
|
||||
init { features }
|
||||
|
||||
pack(nodeId, transport) {
|
||||
from P2PBox.pack(nodeId, transport) // ビルトイン初期化
|
||||
me.features = new ArrayBox()
|
||||
print("🌐 Enhanced P2P Node created: " + nodeId)
|
||||
}
|
||||
|
||||
override send(intent, data, target) {
|
||||
me.features.push("send:" + intent)
|
||||
return from P2PBox.send(intent, data, target)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Static Box Main パターン
|
||||
```nyash
|
||||
static box Main {
|
||||
init { console, result }
|
||||
|
||||
main() {
|
||||
me.console = new ConsoleBox()
|
||||
me.console.log("🎉 Everything is Box!")
|
||||
return "Success!"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 🔄 **制御構造**
|
||||
|
||||
```nyash
|
||||
// 条件分岐
|
||||
if condition {
|
||||
// 処理
|
||||
} else {
|
||||
// 別処理
|
||||
}
|
||||
|
||||
// ループ（唯一の正しい形式）
|
||||
loop(condition) {
|
||||
// 処理
|
||||
if breakCondition {
|
||||
break
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📦 ビルトインBox型
|
||||
|
||||
### 基本型
|
||||
- **StringBox**: 文字列 (`"hello"`)
|
||||
- **IntegerBox**: 整数 (`42`)
|
||||
- **FloatBox**: 浮動小数点数 (`new FloatBox(3.14)`) ✅ Phase 1完了
|
||||
- **BoolBox**: 真偽値 (`true`, `false`)
|
||||
- **NullBox**: NULL値 (`null`)
|
||||
|
||||
### データ構造
|
||||
- **ArrayBox**: 配列 (`new ArrayBox()`) ✅ Phase 1で sort/reverse/indexOf/slice 実装
|
||||
- **MapBox**: 連想配列 (`new MapBox()`)
|
||||
|
||||
### ユーティリティ
|
||||
- **ConsoleBox**: コンソール出力 (`new ConsoleBox()`)
|
||||
- **DebugBox**: デバッグ機能 (`new DebugBox()`)
|
||||
- **MathBox**: 数学関数 (`new MathBox()`)
|
||||
- **TimeBox**: 時刻処理 (`new TimeBox()`)
|
||||
- **DateTimeBox**: 日時処理 (`new DateTimeBox()`) ✅ Phase 1で完全動作
|
||||
|
||||
### 高度機能
|
||||
- **RandomBox**: 乱数生成
|
||||
- **BufferBox**: バッファ操作
|
||||
- **RegexBox**: 正規表現
|
||||
- **JSONBox**: JSON処理
|
||||
- **StreamBox**: ストリーム処理
|
||||
|
||||
### P2P通信 (Phase 2実装中)
|
||||
- **IntentBox**: 構造化メッセージ (実装予定)
|
||||
- **P2PBox**: P2P通信ノード (実装予定)
|
||||
|
||||
---
|
||||
|
||||
## 🚀 実用例
|
||||
|
||||
### データ処理例
|
||||
```nyash
|
||||
// 配列操作
|
||||
local numbers = new ArrayBox()
|
||||
numbers.push(3)
|
||||
numbers.push(1)
|
||||
numbers.push(2)
|
||||
numbers.sort() // [1, 2, 3]
|
||||
|
||||
// 型変換・演算
|
||||
local result = 10 + new FloatBox(3.14) // 13.14
|
||||
print("Result: " + result.toString())
|
||||
```
|
||||
|
||||
### P2P通信例 (将来実装)
|
||||
```nyash
|
||||
// P2Pノード作成
|
||||
local node_a = new P2PBox("alice", transport: "inprocess")
|
||||
local node_b = new P2PBox("bob", transport: "inprocess")
|
||||
|
||||
// メッセージ受信ハンドラ
|
||||
node_b.on("chat.message", function(intent, from) {
|
||||
print("From " + from + ": " + intent.payload.text)
|
||||
})
|
||||
|
||||
// 構造化メッセージ送信
|
||||
local msg = new IntentBox("chat.message", { text: "Hello P2P!" })
|
||||
node_a.send("bob", msg) // → "From alice: Hello P2P!"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ 重要な注意点
|
||||
|
||||
### 必須のコンマ
|
||||
```nyash
|
||||
// ✅ 正しい
|
||||
init { field1, field2 }
|
||||
|
||||
// ❌ 間違い（CPU暴走の原因）
|
||||
init { field1 field2 }
|
||||
```
|
||||
|
||||
### 変数宣言厳密化
|
||||
```nyash
|
||||
// ✅ 明示宣言必須
|
||||
local x
|
||||
x = 42
|
||||
|
||||
// ❌ 未宣言変数への代入はエラー
|
||||
y = 42 // Runtime Error + 修正提案
|
||||
```
|
||||
|
||||
### ループ構文統一
|
||||
```nyash
|
||||
// ✅ 唯一の正しい形式
|
||||
loop(condition) { }
|
||||
|
||||
// ❌ 削除済み構文
|
||||
while condition { } // 使用不可
|
||||
```
|
||||
|
||||

|
||||
|
||||
