# Monorepo 骨架与工具链 Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 搭建 Cocos Creator 子游戏 monorepo 的目录骨架与工具链脚本，做到「一键 `new-game` 生成挂好 framework junction、共享框架真源的子游戏工程」，消灭旧架构「拷贝整份模板」的痛点。

**Architecture:** 框架真源唯一存放于 `cocoscreator_projects/YouleNexus/assets/framework`；各子游戏工程在 `cocoscreator_projects/games/<name>/` 下，通过 Windows junction 把 `assets/framework` 链接到真源实现即时共享。工具链是一组纯 Node ESM 脚本（`setup-links`/`new-game`/`check-cocos-version`/`bump-cocos`），核心逻辑抽到可单测的 `lib/` 纯函数，CLI 入口仅做参数解析与输出。

**Tech Stack:** Node.js 20（ESM `.mjs`）、`node:test` + `node:assert` 内置测试、`node:fs`/`node:crypto`/`node:url` 标准库；无第三方依赖。

> 本计划遵循 spec `docs/superpowers/specs/2026-06-28-cocos-framework-design.md` 的 §2、§7、§8 与 §0.1（协议 SSOT：脚手架产物只引用 `docs/protocol`，不内联协议细节）。

### Task 1: monorepo 工具层脚手架

**Files:**
- Create: `cocoscreator_projects/package.json`
- Create: `cocoscreator_projects/games/.gitkeep`
- Create: `cocoscreator_projects/YouleNexus/assets/framework/README.md`
- Create: `cocoscreator_projects/YouleNexus/assets/framework/{core,net,protocol,platform,ui,sdk}/.gitkeep`
- Modify: `.gitignore`（仓库根，修正 games 路径前缀）

- [ ] **Step 1: 建立工具层 package.json**

创建 `cocoscreator_projects/package.json`：

```json
{
  "name": "youle-monorepo-tools",
  "private": true,
  "type": "module",
  "version": "0.1.0",
  "scripts": {
    "test": "node --test scripts/test/",
    "setup-links": "node scripts/setup-links.mjs",
    "new-game": "node scripts/new-game.mjs",
    "check-cocos": "node scripts/check-cocos-version.mjs",
    "bump-cocos": "node scripts/bump-cocos.mjs"
  }
}
```

- [ ] **Step 2: 建立框架真源占位结构**

创建 `cocoscreator_projects/YouleNexus/assets/framework/README.md`：

```markdown
# framework — 框架真源（唯一权威副本）

各子游戏工程的 `assets/framework` 是指向**本目录**的 junction（见 `scripts/setup-links.mjs`）。
六层结构（依赖严格单向，详见 spec §3）：core / net / protocol / platform / ui / sdk。

协议相关实现一律以 `docs/protocol/` 为唯一信息源（spec §0.1），不在代码或注释中内联复制协议字段。
```

为六层各建一个 `.gitkeep` 空文件占位：
`core/.gitkeep`、`net/.gitkeep`、`protocol/.gitkeep`、`platform/.gitkeep`、`ui/.gitkeep`、`sdk/.gitkeep`。

创建 `cocoscreator_projects/games/.gitkeep`（空文件，使空目录可入库）。

- [ ] **Step 3: 修正仓库根 .gitignore 的 games 路径**

`games/` 实际位于 `cocoscreator_projects/games/`，修正 `.gitignore` 中的链接忽略规则。

将 `.gitignore` 中这两行：

```
games/*/assets/framework
games/*/assets/framework.meta
```

替换为：

```
cocoscreator_projects/games/*/assets/framework
cocoscreator_projects/games/*/assets/framework.meta
```

- [ ] **Step 4: 验证 .gitignore 行为**

Run: `cd G:/Works/YouleGamesCocosCreator && git check-ignore cocoscreator_projects/games/demo/assets/framework`
Expected: 输出 `cocoscreator_projects/games/demo/assets/framework`（命中规则即正确）

- [ ] **Step 5: Commit**

```bash
cd G:/Works/YouleGamesCocosCreator
git add cocoscreator_projects/package.json cocoscreator_projects/games/.gitkeep cocoscreator_projects/YouleNexus/assets/framework .gitignore
git commit -m "chore(monorepo): 工具层脚手架 + 框架真源占位结构

    assert.equal(readCreatorVersion(dir), null);
  } finally {

  try {
    makeGameProject(mono.games, 'doudizhu');
    makeGameProject(mono.games, 'niuniu');
    mkdirSync(join(mono.games, 'not-a-project')); // 无 package.json，应被忽略
    const found = listGameProjects(mono.games).map((p) => p.split(/[\\/]/).pop()).sort();
    assert.deepEqual(found, ['doudizhu', 'niuniu']);
  } finally {

### Task 6: `new-game.mjs` — 一键新建子游戏工程

**Files:**
- Create: `cocoscreator_projects/scripts/test/new-game.test.mjs`
- Create: `cocoscreator_projects/scripts/new-game.mjs`

- [ ] **Step 1: 写失败测试**

创建 `scripts/test/new-game.test.mjs`：

import { test } from 'node:test';
import assert from 'node:assert/strict';
import { join } from 'node:path';

### Task 7: 建立真实种子工程 `templates/game-seed`

> 数据准备任务（非 TDD）：从 YouleNexus 派生一个最小可用的空 Cocos 工程作为种子。new-game 的逻辑已在 Task 6 用 fixture 种子验证；本任务产出运行时使用的真实种子。

**Files:**
- Create: `cocoscreator_projects/templates/game-seed/`（从 YouleNexus 派生）

- [ ] **Step 1: 从 YouleNexus 复制工程级文件（排除业务与缓存）**

Run（在 monorepo 根执行；只复制工程配置，排除 assets 业务内容、缓存、扩展、framework）:

```bash
cd G:/Works/YouleGamesCocosCreator/cocoscreator_projects
mkdir -p templates/game-seed
cp -r YouleNexus/.creator templates/game-seed/ 2>/dev/null || true
cp -r YouleNexus/settings templates/game-seed/ 2>/dev/null || true
cp YouleNexus/package.json templates/game-seed/package.json
mkdir -p templates/game-seed/assets
```

- [ ] **Step 2: 把种子 package.json 的 name 改为 game-seed**

编辑 `templates/game-seed/package.json`，将 `"name": "YouleNexus"` 改为 `"name": "game-seed"`，保留 `creator.version`（`3.8.8`）。`uuid` 字段保持原值即可（new-game 会重新分配）。

- [ ] **Step 3: 校验种子是空且不含 framework/extensions/缓存**

Run:

```bash
cd G:/Works/YouleGamesCocosCreator/cocoscreator_projects
ls templates/game-seed && echo "--- 不应出现 framework/extensions/library/temp ---" && \
( [ ! -e templates/game-seed/assets/framework ] && [ ! -e templates/game-seed/extensions ] && \
  [ ! -e templates/game-seed/library ] && echo "OK: 种子干净" || echo "ERROR: 种子含不应有的内容" )
```

Expected: 打印 `OK: 种子干净`

- [ ] **Step 4: 用真实种子做一次 new-game 冒烟（随后删除产物）**

Run:

```bash
cd G:/Works/YouleGamesCocosCreator/cocoscreator_projects
node scripts/new-game.mjs smoke-demo && \
test -f games/smoke-demo/assets/game/GameModule.ts && \
node -e "const fs=require('fs');const t=fs.lstatSync('games/smoke-demo/assets/framework');console.log('framework isSymlink:', t.isSymbolicLink())" && \
rm -rf games/smoke-demo
```

Expected: 打印 `framework isSymlink: true`，无错误；产物已删除

- [ ] **Step 5: Commit**

```bash
cd G:/Works/YouleGamesCocosCreator
git add cocoscreator_projects/templates/game-seed
git commit -m "chore(tools): 建立真实种子工程 templates/game-seed

### Task 10: 全量测试、端到端冒烟与工具链 README

**Files:**
- Create: `cocoscreator_projects/scripts/README.md`

- [ ] **Step 1: 运行全部单测**

Run: `cd G:/Works/YouleGamesCocosCreator/cocoscreator_projects && node --test scripts/test/`
Expected: PASS — 全部测试通过（7 个测试文件，21 个用例）

- [ ] **Step 2: 端到端冒烟（真实种子 → new-game → check-version → 清理）**

Run:

```bash
cd G:/Works/YouleGamesCocosCreator/cocoscreator_projects
node scripts/new-game.mjs e2e-demo && \
node scripts/check-cocos-version.mjs && \
node scripts/setup-links.mjs && \
rm -rf games/e2e-demo && \
echo "E2E OK"
```

Expected: 依次打印新建工程路径、`OK: 所有子游戏工程版本一致。`、junction 状态、`E2E OK`

- [ ] **Step 3: 编写工具链 README**

创建 `scripts/README.md`：

```markdown
# Monorepo 工具链

所有命令在 `cocoscreator_projects/` 下用 `npm run <script>` 执行。

| 命令 | 作用 |
|------|------|
| `npm run new-game <name>` | 从 `templates/game-seed` 克隆一个子游戏工程到 `games/<name>`，重置身份、铺 `game/` 骨架、挂 framework junction |
| `npm run setup-links` | 为 `games/*` 重建 `assets/framework` junction（clone 仓库后必跑一次） |
| `npm run check-cocos` | 校验所有子游戏工程的 `creator.version` 与宿主 `YouleNexus` 一致（不一致退出码 1） |
| `npm run bump-cocos <version>` | 批量改宿主+所有子游戏的 `creator.version`（之后仍需逐个用编辑器打开迁移） |
| `npm test` | 运行工具链全部单元测试 |

## 关键约束
- **framework 真源**唯一存放于 `YouleNexus/assets/framework`；各子游戏的 `assets/framework` 是指向它的 junction（不入库，见根 `.gitignore`）。clone 后跑 `setup-links` 重建。
- **Cocos 版本必须全 monorepo 统一**（junction 共享同一份资源，跨版本不兼容）。升级走 `bump-cocos` + 逐工程编辑器迁移，详见 spec §8。
- 子游戏私有内容只放 `games/<name>/assets/game/`；协议一律引用 `docs/protocol/`（spec §0.1）。
```

- [ ] **Step 4: Commit**

```bash
cd G:/Works/YouleGamesCocosCreator
git add cocoscreator_projects/scripts/README.md
git commit -m "docs(tools): 工具链 README 与端到端冒烟通过

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>"
```

## 验收标准（Plan 1 完成定义）

1. `node --test scripts/test/` 全绿（7 文件、21 用例）。
2. `npm run new-game <name>` 能生成一个：身份独立（新 uuid）、挂好 framework junction、含 `assets/game/` 骨架的子游戏工程。
3. `npm run setup-links` 幂等重建 junction；`npm run check-cocos` 在版本一致时退出码 0、不一致时为 1。
4. 根 `.gitignore` 正确忽略 `cocoscreator_projects/games/*/assets/framework`。
5. 框架真源 `YouleNexus/assets/framework` 六层占位结构入库；junction 与缓存不入库。

## 后续计划衔接
- **Plan 2（框架内核 net+protocol+core）** 开工前需先：依 `docs/protocol/01、04` 落 `protocol/` 的 TS 类型、确定响应式 Store 选型（spec §9）。
- 框架真源开始有实质代码后，本计划建立的 junction 共享与版本校验即为其提供工程底座。
