Mを直接サポートしていませんが、Spinel で Ruby→C に変換し、EmscriptenでそのCをW
ASMにコンパイルする方法が実現可能です。まず環境を確認します。

コンパイルパイプライン
blackjack.rb ──[Spinel AOT]──▶ blackjack.c ──[Emscripten]──▶
blackjack.wasm
(Ruby) (C, ~400行)
(WebAssembly, 36KB)
4段階の変換:
1. Ruby (src/blackjack.rb) — ゲームロジックをRubyで記述。標準的なRubyに見える
が、Spinelの型推論が効く範囲の構文に限定（Fiberなし、メタプログラミングなし）
2. Spinel AOT Compiler (matz/spinel) —
Ruby全体プログラム型推論を行い、C言語に変換。例えば hand_score(hand) →
sp_hand_score(sp_IntArray* lv_hand)
に変換。型安全なCコードを生成し、ネイティブバイナリより10〜80倍高速に動作する
3. Emscripten — 生成されたCコードを wasm32-unknown-emscripten
ターゲットでコンパイル。-sMODULARIZE=1 でJSファクトリ関数としてラップ
4. Browser (JS) — ボタンクリックごとに createBlackjack()
で新しいWASMインスタンスを生成。stdインターフェース経由でコマンドを渡し、標準
出力からゲーム状態を読む
通信プロトコル（stdin/stdout）
JS → WASM: "hit|1000|100|48291|9,45|32,35|38,40,12,..."
└──┘ └──┘ └──┘ └───┘ └──┘ └───┘ └─────┘
cmd chips bet seed player dealer 残デッキ
WASM → JS: "gameover|bust|900|100|Bust!|9,45,30|32,35|..."
カードは0〜51の整数で符号化（suit=card÷13, value=card%13）。Spinel生成CはRuby
のガベージコレクタ付きランタイムをそのままWASMに載せている。
Spinelとの互換性対応
- malloc_trim() がEmscriptenにないため -Dmalloc_trim(x)=((void)(x)) でno-op化
- 乱数は rand() の代わりに独自LCG（$rng * 1664525 + 1013904223 mod
2147483647）をRuby側で実装し、JSからシードを渡す
- 多値返却（r, chips, msg = func()）はSpinelの型推論でPolyArrayになりCの型エラ
ーが出るため、インライン展開して回避

流れを整理すると：

1. src/blackjack.rb — ゲームロジックをRubyで書く
2. ./spinel/spinel blackjack.rb -S —
Spinelがそれを読んで全体プログラム型推論し、Cコードを生成する
3. emcc generated/blackjack.c — EmscriptenがそのCをWASMにコンパイル
4. ブラウザ — WASMとして実行
たとえば hand_score(hand) というRubyの関数が、Spinelによって
sp_hand_score(sp_IntArray* lv_hand)
という型付きCに変換されています。Spinelが「このhandはInteger配列だ」と推論した
結果が型として現れています（sp_IntArray*）。
直接JavaScriptで書いたわけではなく、RubyコードをSpinelでCにAOTコンパイルし、そ
のCをWASMに載せています。

17 +### 必要なもの
18 +
19 +| ツール | 用途 | インストール |
20 +|--------|------|-------------|
21 +| Ruby 3.x | Spinel のビルドに必要 | `brew install ruby` |
22 +| Emscripten | C → WASM コンパイル | `brew install emscripten`
+ |
23 +| Python 3.10+ | Emscripten の依存 | `brew install python@3.13
+` |
24 +| GNU make | ビルド自動化 | macOS 標準搭載 |
25 +
26 +### ビルド
27 +
28 +```sh
29 +# Spinel のクローン＆ビルド → Ruby → C → WASM をすべて一発で
30 +make
31 +
32 +# 動作確認
33 +make check

75 +## Spinel とは
76 +
77 +[Spinel](https://github.com/matz/spinel) は **Ruby の AOT（Ahe
+ad-of-Time）コンパイラ**。
78 +Ruby ソースに全体プログラム型推論をかけて最適化された C コード
+を生成し、
79 +ネイティブバイナリにコンパイルする。作者は Ruby の作者・まつも
+とゆきひろ（matz）。
80 +
81 +- CRuby 比で **幾何平均 11.6 倍高速**（計算集約的な処理では最
+大 86 倍）
82 +- コンパイラ自身も Ruby で書かれており、**セルフホスト**を達成
+している
83 +- 生成物はスタンドアロンバイナリ（ランタイム不要）
84 +
85 +このプロジェクトでは Spinel の **`-S` フラグ**（C コードを std
+out に出力）を使い、
86 +生成された C を Emscripten に渡すことで WASM として動作させて
+いる。
87 +
88 +---
89 +
90 +## コンパイルパイプラインの詳細
91 +
92 +### ステップ 1: Ruby → C（Spinel）
93 +
94 +```sh
95 +./spinel/spinel src/blackjack.rb -S > generated/blackjack.c
96 +```
97 +
98 +Spinel は Ruby を解析して**全体プログラム型推論**を行い、型付
+きの C コードを生成する。
99 +たとえば `hand_score(hand)` という Ruby の関数は：
100 +
101 +```ruby
102 +# Ruby (src/blackjack.rb)
103 +def hand_score(hand)
104 + total = 0
105 + aces = 0
106 + i = 0
107 + while i < hand.length
108 + p = card_points(hand[i])
109 + if p == 11
110 + aces += 1
111 + end
112 + total += p
113 + i += 1
114 + end
115 + while total > 21 && aces > 0
116 + total -= 10
117 + aces -= 1
118 + end
119 + total
120 +end
121 +```
122 +
123 +`hand` が Integer の配列だと推論され、以下の C に変換される：
124 +
125 +```c
126 +// C (generated/blackjack.c) — Spinel が自動生成
127 +static mrb_int sp_hand_score(sp_IntArray * lv_hand) {
128 + mrb_int lv_total = 0;
129 + mrb_int lv_aces = 0;
130 + mrb_int lv_i = 0;
131 + mrb_int lv_p = 0;
132 + SP_GC_SAVE();
133 + SP_GC_ROOT(lv_hand);
134 + lv_total = 0; lv_aces = 0; lv_i = 0;
135 + mrb_int _t1 = sp_IntArray_length(lv_hand);
136 + while ((lv_i < _t1)) {
137 + lv_p = sp_card_points(sp_IntArray_get(lv_hand, lv_i));
138 + if ((lv_p == 11)) { lv_aces += 1; }
139 + lv_total += lv_p;
140 + lv_i += 1;
141 + }
142 + while (((lv_total > 21) && (lv_aces > 0))) {
143 + lv_total -= 10;
144 + lv_aces -= 1;
145 + }
146 + return lv_total;
147 +}
148 +```
149 +
150 +引数型（`sp_IntArray*`）、変数型（`mrb_int`）、GC ルートの登録
+（`SP_GC_ROOT`）まで
151 +すべて Spinel が推論・生成する。
152 +
153 +### ステップ 2: C → WASM（Emscripten）
154 +
155 +```sh
156 +emcc generated/blackjack.c \
157 + -I spinel/lib \
158 + -O2 \
159 + -Dmalloc_trim(x)=((void)(x)) \ # Emscripten にない関数を n
+o-op 化
160 + -sMODULARIZE=1 \ # JS ファクトリ関数としてラ
+ップ
161 + -sEXPORT_NAME=createBlackjack \
162 + -sEXIT_RUNTIME=1 \
163 + -sFORCE_FILESYSTEM=1 \
164 + -sINVOKE_RUN=0 \ # main() を自動実行しない
165 + "-sEXPORTED_RUNTIME_METHODS=['callMain','FS']" \
166 + -lm \
167 + -o web/blackjack.js
168 +```
169 +
170 +Spinel のランタイム（`sp_runtime.h`）には GC、文字列管理、配列
+実装が含まれており、
171 +これをまるごと WASM に載せている。
172 +
173 +### ステップ 3: WASM ↔ JavaScript（stdin/stdout ブリッジ）
174 +
175 +ゲームロジック（Spinel 生成 WASM）と UI（JavaScript）は **stdi
+n/stdout** で通信する。
176 +ボタンを押すたびに新しい WASM インスタンスを生成し（プリコンパ
+イル済みバイナリを再利用）、
177 +コマンドを stdin として渡し、出力を stdout から受け取る。
178 +
179 +```
180 +JS WASM (Spinel 生成)
181 +─────────────────────────────────────────────────────
182 +stdin ──▶ "hit|1000|100|48291|9,45|32,35|38,40,…"

+,35|…"
187 + └──────┘ └──┘ └──┘ └──┘ └───────────┘
188 + phase result chips bet message
189 +```
190 +
191 +カードは 0〜51 の整数で符号化（`suit = card / 13`、`value = ca
+rd % 13`）。
192 +
193 +```js
194 +// game.js の核心部分
195 +async function wasmRun(inputStr) {
196 + const bytes = new TextEncoder().encode(inputStr + '\n');
197 + let pos = 0, output = '';
198 +
199 + const M = await createBlackjack({
200 + noInitialRun: true,
201 + stdin: () => pos < bytes.length ? bytes[pos++] : null,
202 + print: (line) => { output = line; },
203 + printErr: () => {},
204 + });
205 +
206 + try { M.callMain([]); }
207 + catch (e) { /* ExitStatus は正常終了 */ }
208 +
209 + return output;
210 +}
211 +```
212 +
213 +---
214 +
215 +## Spinel 方言について
216 +
217 +Spinel は Ruby の全機能をサポートしているわけではない。
218 +このプロジェクトで**避けた**Ruby の機能と、その理由：
219 +
220 +| 避けた機能 | 理由 |
221 +|-----------|------|
222 +| `Fiber` | `ucontext.h` を使うため WASM 非対応 |
223 +| `rand` | Spinel から Ruby の `rand` を呼べないため、LCG を自
+前実装 |
224 +| 多値返却 `a, b = func()` | 混合型配列（`PolyArray`）が生成さ
+れ Emscripten で型エラー |
225 +| `eval` / メタプログラミング | Spinel 非対応 |
226 +
227 +乱数は次の LCG（線形合同法）をRubyで実装し、JS から seed を渡
+している：
228 +
229 +```ruby
230 +$rng = seed
231 +def rng_next(max)
232 + $rng = ($rng * 1664525 + 1013904223) % 2147483647
233 + $rng % max
234 +end
235 +```
236 +
237 +---
238 +
239 +## ゲームルール
240 +
241 +- 初期チップ **$1,000**、最低ベット **$10**
242 +- ブラックジャック（最初の2枚で 21）は **1.5倍**払い
243 +- ディーラーは **17 以上**になるまで必ずヒット（ソフト 17 も含
+む）
244 +- ベット変更は各ゲームの開始前のみ可能
245 +
246 +---
247 +
248 +## 開発メモ
249 +
250 +### Emscripten で `malloc_trim` がないエラー
251 +
252 +Spinel のランタイムヘッダ（`sp_runtime.h`）は非 Apple / 非 Win
+dows 環境で
253 +`malloc_trim(0)` を呼ぶが、Emscripten の libc に宣言がない。
254 +コンパイル時に `-Dmalloc_trim(x)=((void)(x))` で no-op に置き
+換えている。
255 +
256 +### 毎回 WASM インスタンスを作り直す理由
257 +
258 +Spinel が生成する C コードの `main()` は1回限りの実行を前提と
+しており、
259 +グローバル変数の初期化が再実行に対応していない。
260 +そのため `callMain()` を複数回呼ぶと GC 状態が壊れる可能性があ
+る。
261 +対策として毎回新しいインスタンスを生成しているが、WASM バイナ
+リは
262 +`ArrayBuffer` としてキャッシュするため再取得は発生しない。
263 +カードゲーム程度のデータ量では体感できるパフォーマンス差はない
+。

⏺ web/ 以下のファイルはすでにコミット済みなので、GitHub Pages の「Source: main
ブランチの /docs フォルダ」か「/ (root)」を使うか、または GitHub Actions
で自動デプロイする方法があります。
一番簡単なのは web/ を docs/ にリネームしてプッシュし、Pages の Source を main
/ docs に設定する方法です。やりますか？
それとも GitHub Actions でビルドからデプロイまで自動化する形（src/blackjack.rb
を push するたびに Spinel + Emscripten でビルドして公開）にしますか？
