## 主な変更点 ### 🎯 戦略の転換と明確化 - PyVMを開発ツールとして位置づけ（本番経路ではない） - EXE-first戦略を明確に優先（build_compiler_exe.sh実装済み） - Phase順序の整理: 15.2(LLVM)→15.3(コンパイラ)→15.4(VM) ### 🚀 セルフホスティング基盤の実装 - apps/selfhost-compiler/にNyashコンパイラMVP実装 - compiler.nyash: メインエントリー（位置引数対応） - boxes/: parser_box, emitter_box, debug_box分離 - tools/build_compiler_exe.sh: ネイティブEXEビルド＋dist配布 - Python MVPパーサーStage-2完成（local/if/loop/call/method/new） ### 📝 ドキュメント整備 - Phase 15 README/ROADMAP更新（Self-Hosting優先明記） - docs/guides/exe-first-wsl.md: WSLクイックスタート追加 - docs/private/papers/: 論文G～L、爆速事件簿41事例収録 ### 🔧 技術的改善 - JSON v0 Bridge: If/Loop PHI生成実装（ChatGPT協力） - PyVM/llvmliteパリティ検証スイート追加 - using/namespace機能（gated実装、Phase 15では非解決） ## 次のステップ 1. パーサー無限ループ修正（未実装関数の実装） 2. EXEビルドとセルフホスティング実証 3. c0→c1→c1'ブートストラップループ確立 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# using — Imports and Namespaces (Phase 15)
|
||
|
||
Status: Accepted (Runner‑side resolution). Selfhost parser accepts using as no‑op and attaches `meta.usings` for future use.
|
||
|
||
Policy
|
||
- Accept `using` lines at the top of the file to declare module namespaces or file imports.
|
||
- Resolution is performed by the Rust Runner when `NYASH_ENABLE_USING=1`.
|
||
- Runner strips `using` lines from the source before parsing/execution.
|
||
- Registers modules into an internal registry for path/namespace hints.
|
||
- Selfhost compiler (Ny→JSON v0) collects using lines and emits `meta.usings` when present. The bridge currently ignores this meta field.
|
||
|
||
Syntax
|
||
- Namespace: `using core.std` or `using core.std as Std`
|
||
- File path: `using "apps/examples/string_p0.nyash" as Strings`
|
||
- Relative path is allowed; absolute paths are discouraged.
|
||
|
||
Style
|
||
- Place all `using` lines at the top of the file, before any code.
|
||
- One using per line; avoid trailing semicolons. Newline separation is preferred.
|
||
- Order: sort alphabetically by target. Group namespaces before file paths.
|
||
- Prefer an explicit alias (`as ...`) when the target is long. Suggested alias style is `PascalCase` (e.g., `Std`, `Json`, `UI`).
|
||
|
||
Examples
|
||
```nyash
|
||
using core.std as Std
|
||
using "apps/examples/string_p0.nyash" as Strings
|
||
|
||
static box Main {
|
||
main(args) {
|
||
local console = new ConsoleBox()
|
||
console.println("hello")
|
||
return 0
|
||
}
|
||
}
|
||
```
|
||
|
||
Runner Configuration
|
||
- Enable using pre‑processing: `NYASH_ENABLE_USING=1`
|
||
- Selfhost pipeline keeps child stdout quiet and extracts JSON only: `NYASH_JSON_ONLY=1` (set by Runner automatically for child)
|
||
- Selfhost emits `meta.usings` automatically when present; no additional flags required.
|
||
|
||
Notes
|
||
- Phase 15 keeps resolution in the Runner to minimize parser complexity. Future phases may leverage `meta.usings` for compiler decisions.
|
||
- Unknown fields in the top‑level JSON (like `meta`) are ignored by the current bridge.
