## 🎉 Phase 134-B: StringBox bridge 分離（完了）✅ 2025-12-04
|
||||
|
||||
### 📋 実装内容
|
||||
|
||||
**目的**: StringBox メソッド処理を boxcall.py から分離し、専用モジュールに集約
|
||||
|
||||
**背景**:
|
||||
- Phase 133 で ConsoleBox 箱化パターン確立
|
||||
- Phase 134-A で mir_call.py unified 設計完成
|
||||
- Phase 134-B で StringBox 箱化により **37.8% 削減達成**
|
||||
|
||||
### 🔧 修正ファイル
|
||||
|
||||
| ファイル | 修正内容 | 重要度 | 行数 |
|
||||
|---------|---------|-------|------|
|
||||
| `src/llvm_py/instructions/stringbox.py` | StringBoxBridge 箱（新規） | ⭐⭐⭐ | +466行 |
|
||||
| `src/llvm_py/instructions/boxcall.py` | StringBox 処理を箱に委譲 | ⭐⭐⭐ | 481→299行 (-182行) |
|
||||
| `docs/development/current/main/phase134b_stringbox_bridge.md` | 実装ドキュメント更新 | ⭐⭐ | +97行 |
|
||||
|
||||
### 💡 技術的解決策
|
||||
|
||||
**StringBox メソッド処理の統合**:
|
||||
- length/len (90行), substring (51行), lastIndexOf (39行) を stringbox.py に集約
|
||||
- NYASH_LLVM_FAST 最適化パス: literal folding, length_cache, string_ptrs
|
||||
- NYASH_STR_CP モード: Code point vs UTF-8 byte 切り替え
|
||||
- Handle-based / Pointer-based 両パス対応
|
||||
|
||||
**Phase 133 パターン継承**:
|
||||
- ConsoleLlvmBridge と同じ箱化モジュール設計
|
||||
- emit_stringbox_call() による統一エントリーポイント
|
||||
- Diagnostic helpers: get_stringbox_method_info()
|
||||
|
||||
### 🎯 成果
|
||||
- **boxcall.py 削減**: 481 → 299行 (**37.8% 削減**)
|
||||
- **StringBox 処理一元化**: 全メソッド処理を stringbox.py に集約
|
||||
- **拡張性向上**: Phase 134-C CollectionBox 分離の準備完了
|
||||
|
||||
### 📌 次のステップ
|
||||
**Phase 134-C: CollectionBox bridge 分離**
|
||||
- Array/Map メソッド処理 (get, push, set, has) を分離
|
||||
- Phase 133/134-B パターンを継承

|

|

### 実装日時
|
||||
2025-12-04 (Claude Code 実装)
|
||||
|
||||
### 修正ファイル
|
||||
1. **新規作成**: `src/llvm_py/instructions/stringbox.py` (466行)
|
||||
- StringBoxBridge 箱化モジュール
|
||||
- length/len, substring, lastIndexOf メソッド lowering 実装
|
||||
- 最適化パス統合 (NYASH_LLVM_FAST, NYASH_STR_CP)
|
||||
- literal folding, length_cache 等の高度な最適化実装
|
||||
|
||||
2. **修正**: `src/llvm_py/instructions/boxcall.py` (481 → 299行)
|
||||
- StringBox メソッド処理 (lines 130-323, ~180行) を削除
|
||||
- 1行の委譲呼び出しに置き換え: `emit_stringbox_call()`
|
||||
- import 追加: `from instructions.stringbox import emit_stringbox_call`
|
||||
|
||||
### 実装内容詳細
|
||||
|
||||
#### StringBoxBridge モジュール構造
|
||||
```python
|
||||
class StringBoxBridge:
|
||||
STRINGBOX_METHODS = {
|
||||
"length": 410,
|
||||
"len": 410, # Alias
|
||||
"substring": 411,
|
||||
"lastIndexOf": 412,
|
||||
}
|
||||
|
||||
# Main dispatcher
|
||||
emit_stringbox_call() # 全 StringBox メソッドの entry point
|
||||
|
||||
# Method-specific handlers
|
||||
_emit_length() # length/len 処理 (literal folding, cache, fast path)
|
||||
_emit_substring() # substring 処理 (NYASH_STR_CP mode)
|
||||
_emit_lastindexof() # lastIndexOf 処理
|
||||
|
||||
# Helper functions
|
||||
_literal_fold_length() # Compile-time length 計算
|
||||
_fast_strlen() # NYASH_LLVM_FAST 最適化パス
|
||||
_codepoint_mode() # NYASH_STR_CP フラグ判定
|
||||
get_stringbox_method_info() # Diagnostic helper
|
||||
```
|
||||
|
||||
#### 最適化パス統合
|
||||
1. **NYASH_LLVM_FAST パス**:
|
||||
- literal folding: `"hello".length()` → `5` (compile-time)
|
||||
- length_cache: 計算済み長さをキャッシュ
|
||||
- string_ptrs: ポインター直接アクセスで高速化
|
||||
- newbox_string_args: StringBox 生成時の引数追跡
|
||||
|
||||
2. **NYASH_STR_CP パス**:
|
||||
- Code point mode vs UTF-8 byte mode 切り替え
|
||||
- substring, length 計算でモード考慮
|
||||
|
||||
3. **Handle-based vs Pointer-based パス**:
|
||||
- i64 handle: nyash.string.*_hii 系関数
|
||||
- i8* pointer: nyash.string.*_sii 系関数
|
||||
|
||||
### テスト結果
|
||||
- ✅ Python import テスト: PASS
|
||||
- `from instructions.stringbox import emit_stringbox_call` 成功
|
||||
- `from instructions.boxcall import lower_boxcall` 成功
|
||||
- ✅ 既存テスト: 変更前と同じ結果 (47 failed は pre-existing, VM関連)
|
||||
- ✅ LLVM backend: インポートエラーなし、構文エラーなし
|
||||
|
||||
### 成果
|
||||
- **boxcall.py 削減**: 481 → 299行 (**37.8% 削減, 182行減**)
|
||||
- **StringBox 処理の一元化**: 全メソッド処理が stringbox.py に集約
|
||||
- **Phase 133 パターン継承**: ConsoleLlvmBridge と同じ設計
|
||||
- **拡張性向上**: Phase 134-C CollectionBox 分離の準備完了
|
||||
|
||||
### 設計原則の踏襲
|
||||
- ✅ Phase 133 ConsoleLlvmBridge パターンを完全継承
|
||||
- ✅ 箱化モジュール化: 1 Box type = 1 dedicated module
|
||||
- ✅ 最適化パスの統合: 環境変数フラグを module 内で管理
|
||||
- ✅ Diagnostic helpers: get_stringbox_method_info() 実装
|
||||
|
||||
### 次のステップ
|
||||
**Phase 134-C: CollectionBox bridge 分離**
|
||||
- boxcall.py:143-193 の Array/Map メソッド処理を分離
|
||||
- get, push, set, has メソッドを collectionbox.py に集約
|
||||
- Phase 133/134-B パターンを継承
