# S1 核心内核实施方案（Mindmap 内核对标 KMind）
|
||||||
|
|
||||||
|
目标：在不改变现有 Next.js + BlockNote + Yjs + Supabase 架构的前提下，完成 Stage S1 中的 5 个核心能力，形成可落地的代码骨架与开发清单。
|
||||||
|
|

## 1. MindmapCanvas（画布容器 / 多根模式 / 懒渲染）
|
||||||
|
|
||||||
|
| 对标 | MNOTE 方案 |
|
||||||
|
|------|-----------|
|
||||||
|
| `design/Kmind/js/0.js:719-1160` 的 `MindMap` 类，负责容器初始化、SVG 分层、大小检测、延迟渲染、多根导图 | 在 `src/components/mindmap/canvas/MindmapCanvas.tsx`（新建）中封装一个 React 组件，内部通过 `@xyflow/react` 的 `ReactFlowProvider` + `useReactFlow` 控制视图。|
|
||||||
|
|
||||||
|
### 关键设计
|
||||||
|
1. **多根模式**：允许 `props.roots` 为数组；在 BlockNote ↔ mindmap 同步时，若一个文档存在多个 mindmap，即 `mindmap_meta` 行 >1，则对每个根节点创建独立的 React Flow `Node` 子树，并在 `MindmapCanvas` 中渲染多个 root。
|
||||||
|
2. **容器重试/懒加载**：借鉴 KMind 的 `containerSizeRetryConfig`，封装 `useElementRect` hook，支持 `IntersectionObserver` 判断是否进入视窗，在进入前仅挂起渲染。
|
||||||
|
3. **SVG 分层**：React Flow 默认使用单一 `svg`；需要添加自定义背景（连线）、节点容器及“其他层”（如选框、直觉按钮）。做法：通过 `ReactFlow` 的 `nodeTypes` + `edgeTypes` + 自定义 `Background`/`Controls` 组件来模拟 `lineDraw`/`nodeDraw`/`otherDraw`。
|
||||||
|
4. **画布状态管理**：使用 Zustand（`src/store/useMindmapStore.ts` 新建）保存 `scale`, `translate`, `activeNodes`, `multiRootMode` 等状态，方便其他模块（快捷键、TextEdit）订阅。
|
||||||
|
|
||||||

### 输出物

||||||

- `src/components/mindmap/canvas/MindmapCanvas.tsx`
|
||||||

## 2. MindLayoutEngine（渲染管线与多布局）
|
||||||
|
|
||||||
|
| 对标 | MNOTE 方案 |
|
||||||
|
|------|-----------|
|
||||||
|
| `Render` 类（`design/Kmind/js/0.js:11753-15120`）整合布局、懒渲染、节点缓存和命令 | 拆成 `MindLayoutEngine`（纯 TS，负责布局计算）和 `MindmapRenderer`（React hook，负责 diff & 渲染）两部分。|
|
||||||
|
|
||||||
|
### 关键设计
|
||||||
|
1. **数据模型**：使用 `MindmapNode`（包含 `id`, `parentId`, `children`, `data`, `layout`）与 `MindmapTree`（单根/多根）。使用 `zod` 校验。
|
||||||
|
2. **布局策略**：引入 elkjs（cjs 版本）或自己实现逻辑结构布局。第一阶段至少实现 `LOGICAL_STRUCTURE` 与 `MIND_MAP`，接口定义：
|
||||||
|
```ts
|
||||||
|
interface LayoutEngine {
|
||||||
|
name: 'logical' | 'mind' | ...;
|
||||||
|
compute(tree: MindmapTree, options: LayoutOptions): LayoutResult;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
3. **节点缓存**：维护 `nodeCache: Map<string, LayoutResultNode>`，当节点数据未变化时复用位置。通过 `useMemo` + `JSON.stringify` diff 或者基于 `hash`.
|
||||||
|
4. **命令注册**：结合 `MindmapCommandBus`（Zustand store + typed events），将 `INSERT_NODE` / `SET_NODE_STYLE` 等命令映射到 `MindLayoutEngine` -> `MindmapRenderer`.
|
||||||
|
5. **Generalization & multi-root**：沿用 KMind 的 `generalization` 数据结构：每个节点 `data.generalization?: { range: [start,end]; text: string }[]`，在布局时对“概要节点”作为独立 branch 处理。
|

|
## 3. MindmapShortcutController（快捷键与命令路由）
|
||||||
|
|
||||||
|
| 对标 | MNOTE 方案 |
|
||||||
|
|------|-----------|
|
||||||
|
| `KeyCommand` （`design/Kmind/js/0.js:11709-11890`） | 创建 `src/components/mindmap/shortcut/MindmapShortcutController.ts`，Hook 化 `keydown` 捕获、实例隔离、编辑模式白名单。|
|
||||||
|
|
||||||
|
### 关键设计
|
||||||
|
1. **多实例隔离**：用一个全域 `activeInstanceId`（ref） + `MindmapCanvas` `useEffect` 控制，仅当前 canvas 响应快捷键。
|
||||||
|
2. **捕获阶段阻断**：在 `document` capture 阶段阻止 `Ctrl+Z`, `Ctrl+V` 等冒泡，若不在 mindmap 内部则放行。
|
||||||
|
3. **映射**：提供 `registerShortcut(keyCombo, handler, options)` API，内部用 `Map<string, ShortcutEntry[]>`，默认注册：新增节点、删除、展开、直觉按钮等。
|
||||||
|
4. **自定义检查**：暴露 `shouldHandleEvent(e)` 回调，允许 BlockNote/其它面板禁用快捷键。
|
||||||
|
|
||||||
|
### 输出物
|
||||||
|
- `src/components/mindmap/shortcut/MindmapShortcutController.ts`
|
||||||
|
- `src/types/mindmap/shortcuts.ts`

## 4. TextEdit 内嵌富文本
|
||||||
|
|
||||||
|
| 对标 | MNOTE 方案 |
|
||||||
|
|------|-----------|
|
||||||
|
| Quill `history/input/keyboard` + `render/TextEdit` | 在 `src/components/mindmap/text` 下实现 `MindmapTextEditor`（挂载于节点上方）与 `useMindmapTextEdit` Hook。|
|
||||||
|
|
||||||
|
### 关键设计
|
||||||
|
1. **编辑器选择**：为了兼容 BlockNote，可采用 `@blocknote/core` 的 `InlineContent` 或 mini TipTap 实例。若沿用 Quill，需要自定义 bubble toolbar + history 模块。
|
||||||
|
2. **实时测量**：使用 `ResizeObserver` 或 canvas measure，模拟 KMind 的 `node.createTextNode` -> `getNodeRect`，在编辑时更新 `width/height` 并触发布局。
|
||||||
|
3. **粘贴清洗**：复用 KMind 的 `handleInputPasteText`、`defenseXSS`（位置 `design/Kmind/js/0.js` utils 部分），转成 TypeScript。
|
||||||
|
4. **撤销栈**：复刻 `history` 模块逻辑，处理 `undo/redo` 按键，保持与 `MindmapShortcutController` 协调。
|
||||||
|
|
||||||
|
### 输出物
|
||||||
|
- `src/components/mindmap/text/MindmapTextEditor.tsx`
|
||||||
|
- `src/components/mindmap/text/useMindmapTextEdit.ts`
|
||||||
|
- `src/lib/mindmap/text/pasteSanitizer.ts`

## 5. Link / Attachment 解析层
|
||||||
|
|
||||||
|
| 对标 | MNOTE 方案 |
|
||||||
|
|------|-----------|
|
||||||
|
| `checkSiyuanLinkFormatData` / `checkSiyuanPdfUrlFormatData` (`design/Kmind/js/0.js:12040-12380`) | 在 `src/lib/mindmap/parser/linkParser.ts` 中封装同功能模块，输出标准化 `MindmapLink`.|
|
||||||
|
|
||||||
|
### 关键设计
|
||||||
|
1. **类型定义**：
|
||||||
|
```ts
|
||||||
|
type MindmapLink =
|
||||||
|
| { type: 'block'; blockId: string; title?: string }
|
||||||
|
| { type: 'document'; documentId: string; title?: string }
|
||||||
|
| { type: 'mindmap-node'; mindmapId: string; nodeId: string }
|
||||||
|
| { type: 'pdf'; path: string; id: string; imageUrl?: string; title?: string }
|
||||||
|
| { type: 'url'; url: string; title?: string };
|
||||||
|
```
|
||||||
|
2. **粘贴入口**：`MindmapTextEditor` 在 `onPaste` 中调用 parser，将结果写入 `node.data.link` 并触发 Command `SET_NODE_HYPERLINK`。
|
||||||
|
3. **附件扩展**：在 parser 中同时识别 `siyuan://plugins/kmind-plugin?data=...`、`siyuan://blocks/`、`((id 'title'))`、PDF 标注、普通 URL。
|
||||||
|
|
||||||
|
### 输出物
|
||||||
|
- `src/lib/mindmap/parser/linkParser.ts`
|
||||||
|
- `src/types/mindmap/link.ts`
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 6. 调试与验证
|
||||||
|
|
||||||
|
- 单元测试：使用 Vitest 对 `MindLayoutEngine`, `linkParser`, `MindmapCommandBus` 编写测试用例（位于 `src/lib/mindmap/__tests__`）。
|
||||||
|
- Storybook/Playground：创建 `src/components/mindmap/dev/MindmapPlayground.tsx`，用于手动测试多根、快捷键、TextEdit。
|
||||||
|
- 集成测试：待 P4 同步控制器完成后，在 Playwright 场景中验证：新增节点 -> 更新 BlockNote -> 重新渲染。
|
||||||
|

-## S1. 核心内核
|
||||||
|
-
|
||||||
|
- [x] **画布容器 / 多根模式 / 懒渲染**
|
||||||
|
参考 `design/Kmind/js/0.js:719-1160` 的 `MindMap` 构造、`_initializeContainer`、`initContainer`、`reRender`、`resize`、`View`，复刻 SVG 分层、容器重试与多根导图的渲染机制，映射到我们的 `MindmapCanvas` / `MindLayoutEngine`。
|
||||||
|
- [x] **渲染管线与布局注册**
|
||||||
|
对齐 `Render` 类（`design/Kmind/js/0.js:11753-15120`）的节点缓存、布局切换、命令注册、懒渲染、generalization 处理；把 LogicalStructure/MindMap/Fishbone 等布局映射成我们自研引擎的 layout API。
|
||||||
|
- [x] **快捷键与命令路由**
|
||||||
|
移植 `KeyCommand` + `keyMap`（`design/Kmind/js/0.js:11709-11890`、`11721-11740`）的多实例冲突、防冒泡捕获、编辑快捷键白名单，落地到 `MindmapShortcutController`。
|
||||||
|
- [x] **富文本输入 / 撤销栈 / 实时测量**
|
||||||
|
复用 `design/Kmind/js/0.js:11114-11290` 的 Quill `history`、`input`、`keyboard` 模块与 `render/TextEdit`，实现节点富文本编辑、粘贴清洗、撤销重做，并与 BlockNote 文档保持同步。
|
||||||
|
- [x] **节点链接 / 附件 / 思源解析**
|
||||||
|
将 `checkSiyuanLinkFormatData`、`checkSiyuanPdfUrlFormatData`、`setNodeSiyuanHyperlink` 等逻辑（`design/Kmind/js/0.js:12040-12380`）改写成我们的 `link`/`attachment` 数据模型，实现块链接、PDF 标注、镜像粘贴解析。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## S2. 交互与 UI
|
||||||
|
|
||||||
|
- [ ] **浮动工具条 / 节点属性面板**
|
||||||
|
按 `design/Kmind/app.js:468-1150` 的 i18n 配置复刻附件、图标、外框、公式、链接、节点属性面板等按钮布局与交互。
|
||||||
|
- [ ] **直觉按钮 & 拖拽建节点**
|
||||||
|
依据 README（`design/kmind-plugin/README.md:103-125`）中“直觉按钮”/禅模式描述，落地相同的拖动建节点体验和提示文案。
|
||||||
|
- [ ] **导航工具栏 / 只读 / 禅模式 / MiniMap**
|
||||||
|
参考 `navigatorToolbar`（`design/Kmind/js/0.js` 内相关实现）及 README 中的 Fullscreen / Zen / Readonly 说明，实现视图控制、全屏、回到根节点、MiniMap。
|
||||||
|
- [ ] **MOC 模式与文档树导图**
|
||||||
|
对照 README（`design/kmind-plugin/README.md:17-37`）与文档树创建导图流程（同文件 365 行附近），完成 BlockNote Outline ↔ Mindmap 的实时映射、增删节点限制、全局配置项。
|
||||||
|
- [ ] **镜像块 / 跨文档嵌入**
|
||||||
|
参考 `design/kmind-plugin/README.md:139-199` 的操作流程，设计 MindmapEmbedWidget：镜像块 copy/paste、跳回源导图、蒙版提示。
|
||||||
|
- [ ] **PDF 标注 & 思源链接处理**
|
||||||
|
结合 README (`design/kmind-plugin/README.md:89-125`) 和核心代码中的 PDF 解析函数，支持粘贴思源 PDF 标注/块引用后自动生成节点链接、缩略图/跳转。

||||||
|
- [ ] **主题 JSON / 主题编辑器**
|
||||||
|
引入 `../simple-mind-map-plugin-themes`（`design/Kmind/js/0.js:3-400`）的 50+ 主题配置，整合 `themeConfig` 机制，支持导入/导出/预览以及 MindManager 风格主题。
|
||||||
|
- [ ] **图标 / 贴纸 / 字体资源**
|
||||||
|
整理 `design/Kmind/img/*.svg` 与 `design/Kmind/fonts/*` 资产，生成 React 可用的图标组件和字体声明，为附件、标签、状态、贴纸 UI 提供素材。
|
||||||
|
- [ ] **导出 / 嵌入 / 全屏 / 小地图等工具**
|
||||||
|
借鉴 `design/Kmind/js/0.js:11114-11580` 与 README 对导出、禅模式、只读、全屏、MiniMap 的描述，实现 PNG/SVG/OPML 导出、嵌入视图与全屏展示。
|
||||||
|
- [ ] **插件/挂件包装**
|
||||||
|
参考 `design/kmind-plugin/plugin.json` 与 `design/kmind-plugin/app/widget.json` 定义的入口、权限和资源结构，规划我们的桌面壳/挂件打包流程。
