feat: add video OCR/ASR, DOCX/PDF export, input block and risk config updates

- Video pipeline: video file OCR via VLM plus audio track ASR, integrated
  into job_handlers with progress emit per phase. New media_utils.py for
  audio extraction from video files.
- Document export: richExport.js replaces inline docx builder; DOCX and PDF
  export buttons are now enabled in MilkdownEditor. File size limit raised to
  100 MB.
- Input block: new InputBlockCrepe.vue component with inputBlockPlugin.ts
  and inputBlock.js for custom user-input nodes in the editor.
- Risk config: added Vite dev server ports (5173) to CORS allowlist and
  increased OCR max input from 10 MB to 100 MB.
- TTS/ASR refactor: simplified tts_asr.py model loading and warmup logic.
- Test coverage: updated tests for llm, main endpoints, pro completions and
  web search modules.

+# 前端代码简化与优化提示词
+
+## 目标
+深入分析并简化前端代码结构，提升执行效率、可维护性和类型安全性。
+
+## 优化原则
+
+### 1. 代码简化
+- **消除冗余**：识别并移除重复的逻辑、条件判断和错误处理模式
+- **函数拆分**：将大型函数拆分为职责单一的小函数（每个函数只做一件事）
+- **提取常量**：将魔法数字、字符串字面量提取为命名常量
+- **减少嵌套**：使用早期返回（early return）替代深层 if/else 嵌套
+
+### 2. 类型安全
+- **明确类型**：为所有函数参数和返回值添加 TypeScript 类型注解
+- **接口定义**：为复杂对象结构定义 interface，避免 `any` 类型
+- **联合类型**：使用 discriminated unions 替代运行时 typeof 检查
+
+### 3. 性能优化
+- **懒加载**：对非核心模块使用动态 import() 
+- **防抖节流**：对频繁触发的事件（输入、滚动）添加 debounce/throttle
+- **计算缓存**：对纯函数的重复计算结果进行 memoization
+- **条件渲染**：使用 v-if/v-show 控制不必要的 DOM 操作
+
+### 4. 错误处理
+- **统一错误边界**：集中处理 fetch/API 调用异常
+- **有意义错误信息**：避免空 catch，提供具体的失败原因
+- **降级策略**：关键功能失败时有优雅的 fallback
+
+### 5. 状态管理
+- **最小化状态**：只存储必要的响应式数据
+- **派生状态**：使用 computed 替代手动监听 + 条件赋值
+- **作用域限制**：将状态定义在尽可能小的组件范围内
+
+## 检查清单
+
+### api.js 优化点
+```typescript
+// ❌ 问题：过多的条件分支和嵌套
+function getCancelUrl(apiUrl) {
+  const normalized = String(apiUrl || '').replace(/\/+$/, '')
+  if (/\/v1\/pro\/completions$/i.test(normalized)) { /*...*/ }
+  if (/\/v1\/web-search$/i.test(normalized)) { /*...*/ }
+  // ...
+}
+
+// ✅ 优化：使用映射表替代条件链
+const CANCEL_PATH_MAP = {
+  '/v1/pro/completions': '/v1/pro/completions/cancel',
+  '/v1/web-search': '/v1/web-search/cancel',
+  '/v1/completions': '/v1/completions/cancel',
+}
+function getCancelUrl(apiUrl) {
+  const base = new URL(apiUrl).pathname.replace(/\/+$/, '')
+  return CANCEL_PATH_MAP[base] || `${base}/cancel`
+}
+```
+
+### 通用模式识别
+1. **重复的 fetch 包装**：提取统一的 `safeFetch()` 函数处理认证头、错误和超时
+2. **SSE 解析器重复**：将 `parseSseEvent` 抽象为可复用的 stream 处理器
+3. **设置状态访问**：避免在每次 API 调用时重新创建 settings store 实例
+4. **条件类型检查**：用 TypeScript discriminated union 替代运行时 `typeof x === 'string'`
+
+## 执行步骤
+
+### 第一步：分析
+1. 使用 `grep_search` 查找重复模式（相同的 if/else 块、try/catch）
+2. 使用 `semantic_search` 查找相似功能的不同实现
+3. 识别高频调用的函数（API 请求、事件处理器）
+
+### 第二步：重构
+1. **提取纯函数**：将副作用（fetch、DOM操作）与数据处理分离
+2. **创建工具库**：将通用逻辑移至 `src/utils/` 下的独立模块
+3. **添加类型定义**：在 `src/plugins/types.ts` 中集中管理接口
+4. **简化条件逻辑**：用策略模式或映射表替代 switch/if 链
+
+### 第三步：验证
+1. 运行 `npm run build` 确认无类型错误
+2. 检查 `get_errors` 确保没有引入新问题
+3. 手动测试关键路径（补全、OCR、上传）
+
+## 输出格式
+
+每次优化后提供：
+```markdown
+### 优化项: [函数名/文件名]
+
+**问题**: [简要描述当前代码的问题]
+
+**改动**:
+```diff
+- // 旧代码
++ // 新代码
+```
+
+**收益**: 
+- 行数减少: X%
+- 时间复杂度: O(n) → O(1)
+- 可读性提升: [具体说明]
+```
+
+## 示例调用
+
+```bash
+# 简化 api.js 中的 URL 处理逻辑
+"简化 src/utils/api.js 中 getCancelUrl() 函数的条件分支，使用映射表替代正则匹配"
+
+# 优化 copilotPlugin.ts 的类型定义  
+"为 src/plugins/copilotPlugin.ts 添加完整的 TypeScript 类型注解，消除所有 any 类型"
+
+# 提取重复的错误处理
+"将 src/utils/api.js 中分散的 try/catch 错误处理提取为统一的 errorBoundary() 高阶函数"
+```
+
+## 注意事项
+
+- ✅ 保持向后兼容：不破坏现有 API 接口和事件流
+- ✅ 小步快跑：每次只优化一个函数或模块，验证后再继续
+- ❌ 避免过度优化：不要为了炫技引入复杂的函数式编程模式
+- ⚠️ 测试覆盖：修改核心路径（补全、取消请求）前确保有对应测试
+- 📝 文档同步：更新 CLAUDE.md 和 AGENTS.md 中的架构描述

+
+## 功能块系统（核心概念）
+
+- **统一命名**：文档块、PRO 块、上传块统称为"功能块"。
+- **禁止嵌套**：所有功能块的 schema 均设 `atom: true, isolating: true`，ProseMirror 层面强制禁止互相嵌套。DocBlockCrepe.vue 的嵌套 Crepe 编辑器不注册任何功能块插件，从架构上杜绝深层嵌套。
+- **无数量限制**：一篇文档可包含任意数量的功能块，彼此独立存在。
+- **导入自动解析**：从 Markdown 文件导入后，各功能块语法必须通过对应的 Remark/parseMarkdown 解析器自动识别并还原为交互卡片。
+- **导出可复原**：通过 toMarkdown/leafText 序列化器将功能块还原为 Markdown 语法，确保导出后再次导入能完整复原。doc_block toMarkdown 输出 legacy HTML tag，`getExportMarkdown()` 中通过 `transformLegacyDocBlocksForExport()` 转换为 fenced code block。
+
+| 类型 | Node Type | Markdown 语法 | Plugin 文件 | Utility 文件 |
+|------|-----------|---------------|-------------|--------------|
+| 文档块 | `doc_block` | \`\`\`llm-file fenced code / `<doc_type=...>` legacy HTML tag | `plugins/docBlockPlugin.ts` | `utils/docBlock.js` |

 ## 稳定事实
 
-- 补全接口当前不是 SSE；前端用普通 POST 请求拿 JSON 响应。
+- **功能块禁止嵌套**：`doc_block`、`pro_block`、`upload_block` 的 schema 均设 `atom: true, isolating: true`，ProseMirror 层面强制禁止互相嵌套。DocBlockCrepe.vue 的嵌套 Crepe 编辑器仅注册 copilotPlugin + hiddenText*，不注册任何功能块插件。修改时不得移除 atom/isolating 属性或在嵌套编辑器中引入功能块插件。
+- **功能块导入解析**：各功能块的 Remark 插件（`docBlockRemark`, `proBlockRemark`, `uploadBlockRemark`）负责从 Markdown AST 识别对应语法并转换为节点。doc_block Remark 同时支持 fenced code (`llm-file`) 和 legacy HTML tag (`<doc_type=...>`)。解析链路必须保持完整，否则导入后无法自动复原。
+- **功能块导出序列化**：doc_block 的 `toMarkdown` runner 输出 legacy HTML tag，但 `getExportMarkdown()` 中通过 `transformLegacyDocBlocksForExport()` 转换为 fenced code block。pro_block/upload_block 的 toMarkdown/leafText 直接输出标准语法。修改时需验证导出后再次导入能完整复原。
+- **Web Search 块语法**：web_search_block 使用 fenced code ```llm-websearch date=... 语法，与 doc_block(llm-file)、pro_block([PRO])、upload_block({{{}}}) 并列。触发语法为 [WEBSEARCH]（不区分大小写），由 `webSearchBlockPlugin.ts` 处理。
+- **Store 同步格式**：`scheduleMarkdownSync()` emit markdown 不做转换（doc_block 为 legacy HTML tag），store 中始终是 legacy format。`syncInitialMarkdown()` / `getExportMarkdown()` 负责格式转换。
+- **上传块生命周期**：upload_block 是临时占位符，文件上传后被替换为 image node（图片）或 doc_block（文档），不会与 pro_block 共存。
+- **PRO block escape/unescape**：`escapeProBlockContent()` / `unescapeProBlockSyntax()` 处理 `\`, `]`, `}`, newline，确保指令 round-trip 正确。
+- **补全接口当前不是 SSE**；前端用普通 POST 请求拿 JSON 响应。
+- **任务队列架构（v0.2.0 新增）**：后端从同步端点转向 Redis Streams 异步队列。`job_system.py` 定义 JOB_TYPES（completion/pro_completion/web_search/compress/ocr/convert/tts/asr），`worker.py` 消费队列，`job_handlers.py` 注册各类型处理器。所有任务支持并发控制、速率限制和熔断器模式。
+- **会话追踪**：`session_store.py` 提供 InMemorySessionStore（开发）和 PostgresSessionStore（生产），通过 session_hash + ip_hash 追踪请求身份。
+- **风控系统**：`risk_config.py` + `risk_control.py` 实现速率限制（滑动窗口）、并发控制、熔断器模式和预算追踪，所有阈值通过环境变量配置。
 - 前端会生成 X-Request-Id，并在请求被中止时额外调用 /v1/completions/cancel。
 - 文档超过 32 KB 时，AI 补全会在前端和插件层被禁用。
 - OCR 文本和文档块内容会被注入补全上下文，但这些内容属于隐藏上下文，不应被直接当作用户可见文本重复输出。
 - /v1/convert 当前支持 txt、docx、pptx、pdf，非 txt 文件通过 MarkItDown 转成 Markdown，之后会清理图片标记。
-- 前端存在 /v1/export/pdf 调用点，但当前后端主路由中看不到同名端点；排查 PDF 导出问题前先确认服务端是否真正提供该接口。
-- 当前 tts_asr.py 主要提供 TTS 相关能力。不要直接沿用 README 或历史修复文档里关于 ASR、Whisper、MPS/offline 的描述。
+- **AI 开关是全局广播状态**：MilkdownEditor.vue 通过 `llm-in-text:copilot-toggle` 同步主编辑器、文档块嵌套编辑器、网页搜索块嵌套编辑器；修 ghost text 时要同时检查这三处。
+- **设置项已从 currency 改为 country**：前后端请求、prompt、store、设置面板统一使用 `country`；仅在读取旧 localStorage 时兼容 `currency` 作为迁移兜底。
+- **DOCX/PDF 导出改为纯前端**：不再依赖 `/v1/export/pdf`。当前策略是先展开所有功能块，再从编辑器 HTML 构建导出内容；`src/utils/richExport.js` 负责 HTML -> PDF / DOCX。
+- **上传单文件限制统一为 100MB**：前端校验和后端 OCR 风控上限都按 100MB 处理。
+- **视频解析策略**：上传视频时，后端 `/v1/ocr` 接收 `media_type=video`，视频画面走 OCR 模型，音轨通过 ffmpeg 抽取后走 ASR 模型，最终合并为“视频画面 OCR + 视频音频 ASR”文本。
+- **OCR 明确关闭思考**：backend/llm.py 的 OCR payload 显式下发 `options.think = False` 与 `temperature = 0`。
+- **TTS/ASR 当前真实实现**：backend/tts_asr.py 已切到 `Qwen3TTSModel + faster-whisper` 路线；不要继续按旧的 MLX-only 文档理解当前实现。

+- 本机部署目录固定在 `/Users/allenyuan/lit/` 下，不在仓库外再散落数据库或 Docker 持久化目录。
+- 当前推荐的部署工作目录是 `/Users/allenyuan/lit/llm-in-text/`；把仓库同步到该目录后，从该目录执行 `docker compose up -d --build`。
+- 不再使用 `/Volumes/New Volume/lit/` 部署本项目；迁移时可放弃旧 PostgreSQL 数据，从新部署目录初始化空数据库。
+- **docker-compose.yml 定义的服务**：api（FastAPI）、worker（任务消费者）、frontend（Nginx）、postgres（审计+会话存储）、redis（任务队列）、searxng（网页搜索后端）、firecrawl（网页内容抓取）。每次 `docker compose up --build` 后，必须验证所有目标服务（api/worker/frontend/postgres/redis）是否处于 Up 状态。
+- **前端网络硬约定**：前端 API 必须调用 `https://api.imageteach.tech:8002/` 反向代理，不要让前端调用 Docker 内 `api` 服务、本机 `localhost:8001`、`localhost:8081` 或同源 `/v1` 代理。网络和反向代理由外部配置处理，除非用户明确要求，不要新增或恢复前端到 Docker 后端的代理。
+- 每次修改会影响 Docker 运行效果的代码后，不能只停留在本地测试；必须同步更新当前 Docker 环境中的代码，并验证容器内代码已经变化。
+- 首选更新方式：
+	1. 在仓库根目录执行 `docker compose up -d --build`。
+	2. 执行 `docker compose ps` 确认 `api`、`worker`、`frontend` 等目标服务已重新创建并处于 Up。
+	3. 对关键修复点执行容器内验证，例如 `docker compose exec -T worker sh -lc "python - <<'PY'\nfrom pathlib import Path\nprint('_normalize_preferences' in Path('/app/backend/prompt.py').read_text())\nPY"`。
+- 如果 `docker compose build` 因 Docker Hub、镜像源、网络 token 超时等外部原因无法拉基础镜像，仍然必须更新正在运行的 Docker 环境。可用应急方式：
+	1. 先执行 `npm run build` 生成最新前端产物。
+	2. 用 `docker cp` 将改动后的后端文件复制到 `api` 和 `worker` 容器的 `/app/backend/`，必要时将 `dist/` 复制到 `frontend` 容器的 `/usr/share/nginx/html/`。
+	3. 执行 `docker compose restart api worker frontend` 重启受影响服务。
+	4. 执行 `docker commit llm-in-text-api-1 llm-in-text-api:latest`、`docker commit llm-in-text-worker-1 llm-in-text-worker:latest`；如果更新了前端，也执行 `docker commit llm-in-text-frontend-1 llm-in-text-frontend:latest`。
+	5. 执行 `docker compose up -d --no-build --force-recreate api worker frontend`，确保新容器来自已更新镜像。
+	6. 再次用 `docker compose exec -T ...` 验证容器内文件和行为，不能只看本地文件。
+- Docker 持久化数据统一落在部署目录内的 `docker-data/`，包括 PostgreSQL、Redis 和任务共享临时目录。
+- 容器内访问宿主机模型服务时，不要继续使用 `localhost`；应改成 `host.docker.internal` 之类的容器可达地址。
+- 当前 Docker 部署的 `backend/requirements.docker.txt` 已包含 OCR、转换、队列以及 `torch` / `qwen-tts` / `faster-whisper`，并在 `backend/Dockerfile` 中额外安装 `ffmpeg` 以支持视频拆音轨。
+- **Worker 容器**：worker.py 作为独立服务运行，通过 Redis Streams 消费任务队列。修改 job_handlers.py 或 worker.py 后需要验证 worker 容器内的代码已更新，可通过 `docker compose exec -T worker sh -lc "python -c 'from backend.job_handlers import get_handler; print(get_handler(\"completion\").__name__)'"` 验证。
+- **Redis Streams 架构**：任务队列使用 Redis Streams，支持并发控制、速率限制和熔断器。job_system.py 定义 JOB_TYPES 和队列配置，worker.py 注册处理器并运行事件循环。
+- 修改 Docker 相关文件时，除了代码本身，还要同步检查：
+	- `docker-compose.yml`
+	- `backend/Dockerfile`
+	- `backend/requirements.docker.txt`
+	- `Dockerfile.frontend`
+	- `docker/nginx.conf`
+	- `backend/.env.example` 与实际部署用 `backend/.env`

 ## Project Overview
 
-**LLM in Text** is an AI-powered Markdown editor built with Vue 3 + Vite (frontend) and FastAPI + Python + Ollama (backend). It provides real-time AI completion suggestions, OCR image recognition, document conversion (PDF/DOCX/PPTX to Markdown), and TTS text-to-speech.
+**LLM in Text** is an AI-powered Markdown editor built with Vue 3 + Vite (frontend) and FastAPI + Python + Ollama + Redis Streams (backend). It provides real-time AI completion suggestions, OCR image recognition, document conversion (PDF/DOCX/PPTX to Markdown), TTS text-to-speech, web search integration (via SearXNG + Firecrawl), CAPTCHA verification, and async job queue processing.
 
 - Completion interface uses plain POST/JSON (not SSE). Frontend sends `X-Request-Id` and calls `/v1/completions/cancel` on abort.
 - AI completion is disabled when the document exceeds 32 KB (enforced both in UI and plugin layer).
 - OCR text and doc-block content are injected into completion context as hidden context — they should NOT be rendered as visible user text.
 - `/v1/convert` supports txt, docx, pptx, pdf via MarkItDown. Non-txt files go through Markdown sanitization (image removal, newline compression).
 - `/v1/export/pdf` is called from the frontend but may not be implemented on the backend — verify before debugging PDF export.
+- **Task queue architecture (v0.2.0 new)**: Backend shifted from synchronous endpoints to Redis Streams async queue. `job_system.py` defines JOB_TYPES (completion/pro_completion/web_search/compress/ocr/convert/tts/asr), `worker.py` consumes the queue, `job_handlers.py` registers handlers per type. All tasks support concurrency control, rate limiting, and circuit breakers.
+- **Session tracking**: `session_store.py` provides InMemorySessionStore (dev) and PostgresSessionStore (prod), tracking request identity via session_hash + ip_hash.
+- **Risk control system**: `risk_config.py` + `risk_control.py` implement rate limiting (sliding window), concurrency limits, circuit breaker pattern, and budget tracking — all thresholds via environment variables.

 - Python 使用 4 空格缩进。
 - 函数、变量使用 snake_case，类使用 PascalCase。
-- 新逻辑优先保留显式类型和明确的输入输出。
-- 异步边界要清晰；阻塞操作优先放进 asyncio.to_thread，而不是直接阻塞事件循环。
-- 异常要么转成 HTTPException，要么转成结构化 JSONResponse；不要静默吞掉后端错误。
-- 日志尽量带 request_id 或短 tag，便于把前后端一次请求串起来。

 ## 容易误判的点
 
-- 补全接口当前不是流式响应，不要按 SSE 方式改造周边代码。
-- ACTIVE_COMPLETIONS 在补全和取消路径里都被读写，任务生命周期要谨慎处理。
-- main.py 里虽然有 _convert_docx_to_pdf 辅助函数，但当前 /v1/convert 路径实际走的是 MarkItDown，不要误以为 DOCX 转 PDF 桥接脚本已接入主流程。
-- API_KEY 存在占位默认值，这更像本地开发兜底，不是推荐的安全模式。
-- 历史 TTS/ASR 文档和部分测试覆盖的是旧实现；代码与文档冲突时，先确认产品方向，再决定修代码还是修文档。
+- **任务队列架构（v0.2.0 新增）**：后端从同步端点转向 Redis Streams 异步队列。job_system.py 定义 JOB_TYPES，worker.py 消费队列，job_handlers.py 注册各类型处理器。
+- **会话追踪**：session_store.py 提供 InMemorySessionStore（开发）和 PostgresSessionStore（生产），通过 session_hash + ip_hash 追踪请求身份。
+- **风控系统**：risk_config.py + risk_control.py 实现速率限制（滑动窗口）、并发控制、熔断器模式和预算追踪，所有阈值通过环境变量配置。
+- **验证码路由**：captcha_api.py 提供 /captcha/generate 和 /captcha/verify 端点，用于前端验证用户输入。
+- **文档存储**：docs_store.py 提供 MIME 类型检测、文本/二进制分类和预览提取（8MB 限制）。
+- **LLM 策略解析**：llm_policy.py 按 job_type 解析模型配置（模型名、温度、最大 token、思考级别）。
+- **OCR 明确关闭思考**：llm.py 的 `call_vlm_ocr` 对 OCR 请求显式设置 `options.think = False` 和 `temperature = 0`。
+- **补全接口当前不是流式响应，不要按 SSE 方式改造周边代码。**
+- **ACTIVE_COMPLETIONS 在补全和取消路径里都被读写，任务生命周期要谨慎处理。**
+- **`/v1/export/pdf` 不是当前主链路**；DOCX/PDF 导出已经转到前端 `src/utils/richExport.js`。
+- **API_KEY 存在占位默认值，这更像本地开发兜底，不是推荐的安全模式。**
+- **历史 TTS/ASR 文档和部分测试覆盖的是旧实现；代码与文档冲突时，先确认产品方向，再决定修代码还是修文档。**
 
 ## 改动时的定位建议
 
-- 如果问题是补全结果不对，先查 prompt.py，再查 llm.py，不要只盯着 main.py。
-- 如果问题是取消不生效，先查 main.py 里的 request_id 生命周期，再对照前端的 X-Request-Id 和 cancel 调用。
-- 如果问题是 OCR 识别为空，先看 main.py 的 base64 解码，再看 llm.py 的 call_vlm_ocr。
-- 如果问题是转换结果脏，重点看 main.py 里的 _sanitize_converted_markdown。
-- 如果问题是 TTS 行为和文档不一致，以 tts_asr.py 为准，不要以 README 为准。

+- **如果问题是会话丢失，检查 session_store.py 的 InMemory/Postgres 后端切换逻辑。**
+- **如果问题是风控触发，检查 risk_config.py 的环境变量配置和风险阈值。**

-# Announcing Telemetry Inspector
-
-There's a lot of questions from community asking that how can they know what plugins are enabled.
-From Milkdown@7.2, we've added telemetries for milkdown, it can be available by inspectors.
-
-With this API, you can inspect editor inner status.
-You can even use visualizer to visualize the data. We create a simple example on [our playground](/playground).
-
-![Milkdown Inspector](/blogs/announcing-telemetry-inspector/milkdown-inspector.gif)
-
-## Get Started
-
-Inspector will be a top-level API in Milkdown. You can use it like this:
-
-```ts
-import { Editor } from "@milkdown/core";
-import { Telemetry } from "@milkdown/ctx";
-
-const editor = await Editor.make()
-  // Inspector is disabled by default considering performance. You need to enable it manually.
-  .enableInspector()
-  // ...
-  .create();
-
-const telemetry: Telemetry[] = editor.inspect();
-```
-
-The `Telemetry` interface will have the following fields:
-
-```ts
-interface Telemetry {
-  // User defined information for the plugin.
-  metadata: Meta;
-
-  // The slices and their current value defined by the plugin.
-  injectedSlices: { name: string; value: unknown }[];
-
-  // The slices and their current value consumed by the plugin.
-  consumedSlices: { name: string; value: unknown }[];
-
-  // The timers and their duration defined by the plugin.
-  recordedTimers: { name: string; duration: number; status: TimerStatus }[];
-
-  // The timers and their duration consumed by the plugin.
-  // Generally, the plugin will wait for them.
-  waitTimers: { name: string; duration: number; status: TimerStatus }[];
-}
-
-type TimerStatus = "pending" | "resolved" | "rejected";
-
-interface Meta {
-  displayName: string;
-  description?: string;
-  package: string;
-  group?: string;
-  additional?: Record<string, any>;
-}
-```
-
-For every plugin, it'll have a telemetry if it has metadata declared.
-With the data, you'll know the sequence of the plugins loaded, the slices and timers they defined and consumed.
-For example:
-
-```ts
-[
-  {
-    metadata: {
-      displayName: "Config",
-      package: "@milkdown/core",
-      group: "System",
-    },
-    injectedSlices: [],
-    consumedSlices: [
-      /* ... */
-    ],
-    recordedTimers: [
-      {
-        name: "ConfigReady",
-        duration: 3,
-        status: "resolved",
-      },
-    ],
-    waitTimers: [],
-  },
-  {
-    metadata: {
-      displayName: "Init",
-      package: "@milkdown/core",
-      group: "System",
-    },
-    injectedSlices: [],
-    consumedSlices: [
-      /* ... */
-    ],
-    recordedTimers: [
-      {
-        name: "InitReady",
-        duration: 5,
-        status: "resolved",
-      },
-    ],
-    waitTimers: [
-      {
-        name: "ConfigReady",
-        duration: 5,
-        status: "resolved",
-      },
-    ],
-  },
-];
-```
-
-From above information, we can know that the `Init` plugin wait for `Config` plugin to be ready.
-We can build a sequence diagram from the data.
-
-![Timer Sequence](/blogs/announcing-telemetry-inspector/timer-sequence.gif)
-
-## Add Metadata for Plugin
-
-For plugin maintainers, you can add metadata to your plugin to make it more friendly to the inspector.
-
-```ts
-import { MilkdownPlugin } from "@milkdown/ctx";
-
-const yourMilkdownPlugin: MilkdownPlugin = () => {
-  /* your implementation */
-};
-
-yourMilkdownPlugin.metadata = {
-  displayName: "Your Plugin",
-  package: "your-plugin-package",
-  description: "Your plugin description",
-  group: "If you have a lot of plugins in your package, you can group them.",
-  addtitional: {
-    /* You can add any additional information here. */
-    version: "1.0.0",
-    authror: "Mike",
-  },
-};
-```
-
-With metadata, your plugin will report telemetry correctly to the inspector.

-# Build Your Own Milkdown Copilot
-
-OpenAI introduced ChatGPT in 2020, which is a chatbot that can generate natural language responses to user input.
-Which brings us a new way to interact with devices and applications.
-Nowadays, there are more and more tools that are powered by AI. Such as Notion, GitHub and even Microsoft 365.
-
-Since OpenAI also released the [API](https://openai.com/blog/openai-api) of it. And Milkdown is composed by plugins.
-I think it's possible to build a Milkdown Copilot Plugin that can help you write documents. So I did it.
-Let's see the result.
-
-![Milkdown Copilot](/blogs/build-your-own-milkdown-copilot/milkdown-copilot.gif)
-
-Looks cool, right? But how does it work? I'll explain it in the following sections.
-
-## Prepare a Backend
-
-**Before we start, you need to have a OpenAI API Key.** You'll need to get one [here](https://platform.openai.com/account/api-keys).
-I'll not explain how to get it. You can find the details in their [official docs](https://platform.openai.com/).
-
-I'll use Node.js to build the backend. You can use any language you like.
-The backend is very simple. It just calls the OpenAI API and returns the result.
-
-```ts
-import { Configuration, OpenAIApi } from "openai";
-
-const configuration = new Configuration({
-  // Get your API key from env variable
-  apiKey: process.env.OPENAPI_KEY,
-});
-const openai = new OpenAIApi(configuration);
-
-export const handler = async (req, res, next) => {
-  if (req.path === "/api/copilot" && req.method === "POST") {
-    const buffers = [];
-
-    // Get the body of the request.
-    const body = JSON.parse(req.body);
-
-    // Get prompt from the body.
-    const { prompt } = body;
-    const completion = await openai.createCompletion({
-      // Pick a model you like
-      model: "text-davinci-003",
-      prompt,
-    });
-    const hint = completion.data.choices[0].text;
-    return res.end(JSON.stringify({ hint }));
-  }
-  next();
-  return;
-};
-```
-
-We watch the `/api/copilot` route and call the OpenAI API when we receive a POST request.
-The post request should contain a `prompt` field which is the text that we want to complete.
-
-To call our API, we just need one single helper in browser environment:
-
-```ts
-async function fetchAIHint(prompt: string) {
-  const data: Record<string, string> = { prompt };
-  const response = await fetch("/api/copilot", {
-    method: "POST",
-    body: JSON.stringify(data),
-  });
-  const res = (await response.json()) as { hint: string };
-  return res.hint;
-}
-```
-
-## Build a Milkdown Plugin
-
-Now let's focus on the Milkdown Copilot Plugin.
-
-Basically I want to implement two things:
-
-1. When the user types `<Enter>` or `<Space>`, they will get a hint from the copilot.
-2. When the user types `<Tab>`, they will apply the content from the hint to the editor.
-
-### Overview
-
-To build a bridge between the copilot and the editor,
-we can build a prosemirror plugin and use the `onKeyDown` hook to listen to the keydown event.
-
-```ts
-function keyDownHandler(ctx: Ctx, event: Event) {
-  if (event.key === "Enter" || event.code === "Space") {
-    getHint(ctx);
-    return;
-  }
-  if (event.key === "Tab") {
-    // prevent the browser from focusing on the next element.
-    event.preventDefault();
-
-    applyHint(ctx);
-    return;
-  }
-
-  hideHint(ctx);
-}
-```
-
-When the user types `<Enter>` or `<Space>`, we will call the `getHint` function to get a hint from the copilot.
-And when the user types `<Tab>`, we will call the `applyHint` function to apply the hint to the editor.
-If user types other keys, we will hide the hint.
-
-And we also need a component to render the hint. Here I choose to use a simple [widget decoration in prosemirror](https://prosemirror.net/docs/ref/#view.Decoration^widget).
-
-```ts
-function renderHint(message: string) {
-  const dom = document.createElement("pre");
-  dom.className = "copilot-hint";
-  dom.innerHTML = message;
-  return dom;
-}
-```
-
-So our component looks like:
-
-```ts
-import { Plugin, PluginKey } from "@milkdown/prose/state";
-import { Decoration, DecorationSet } from "@milkdown/prose/view";
-import { $prose } from "@milkdown/utils";
-
-const initialState = {
-  deco: DecorationSet.empty,
-  message: "",
-};
-
-export const copilotPluginKey = new PluginKey("milkdown-copilot");
-export const copilotPlugin = $prose(
-  (ctx) =>
-    new Plugin({
-      key: copilotPluginKey,
-      props: {
-        handleKeyDwon(view, event) {
-          keydownHandler(ctx, event);
-        },
-        decorations(state) {
-          return copilotPluginKey.getState(state).deco;
-        },
-      },
-      state: {
-        init() {
-          return { ...initialState };
-        },
-        apply(tr, value, _prevState, state) {
-          const message = tr.getMeta(copilotPluginKey);
-          if (typeof message !== "string") return value;
-
-          if (message.length === 0) {
-            return { ...initialState };
-          }
-
-          const { to } = tr.selection;
-          const widget = Decoration.widget(to + 1, () => renderHint(message));
-          return {
-            deco: DecorationSet.create(state.doc, [widget]),
-            message,
-          };
-        },
-      },
-    }),
-);
-```
-
-### Get Hint
-
-To get a hint from the copilot, we need to get the text before the cursor.
-
-```ts
-function getHint(ctx: Ctx) {
-  const view = ctx.get(editorViewCtx);
-  const { state } = view;
-  const { tr, schema } = state;
-  const { from } = tr.selection;
-
-  const slice = tr.doc.slice(0, from);
-  const serializer = ctx.get(serializerCtx);
-  const doc = schema.topNodeType.createAndFill(undefined, slice.content);
-  if (!doc) return;
-
-  const markdown = serializer(doc);
-  fetchAIHint(markdown).then((hint) => {
-    const tr = view.state.tr;
-    view.dispatch(tr.setMeta(copilotPluginKey, hint));
-  });
-}
-```
-
-1. First of all, we get the `selection` from the `state` of the editor.
-2. Then we get a `slice` of the document from the start to the cursor.
-3. Then we use the `serializer` to convert the slice to markdown.
-4. After that, we call the `fetchAIHint` function to get a hint from the copilot.
-5. Finally, we dispatch a transaction with the hint message we get to update the state of the editor.
-
-### Hide Hint
-
-To hide the hint, we just need to dispatch a transaction with an empty message.
-
-```ts
-function hideHint(ctx: Ctx) {
-  const view = ctx.get(editorViewCtx);
-  const { state } = view;
-  const { tr } = state;
-  view.dispatch(tr.setMeta(copilotPluginKey, ""));
-}
-```
-
-### Apply Hint
-
-Since we pass markdown to the OpenAI API. It may return a markdown snippet.
-
-So, before we apply the hint to the editor, we need to convert the markdown snippet to prosemirror node.
-
-```ts
-function applyHint(ctx: Ctx) {
-  const view = ctx.get(editorViewCtx);
-  const { state } = view;
-  const { tr, schema } = state;
-
-  const { message } = copilotPluginKey.getState(state);
-  const parser = ctx.get(parserCtx);
-  const slice = parser(message);
-  const dom = DOMSerializer.fromSchema(schema).serializeFragment(slice.content);
-  const node = DOMParser.fromSchema(schema).parseSlice(dom);
-
-  // Reset the hint since it's applied
-  tr.setMeta(copilotPluginKey, "")
-    // Replace the selection with the hint
-    .replaceSelection(node);
-
-  view.dispatch(tr);
-}
-```
-
-1. First of all, we get the hint message from the state of the editor.
-2. Then we use the `parser` to convert the markdown snippet to prosemirror node.
-3. Finally, we dispatch a transaction to replace the selection with the hint.
-
-## Conclusion
-
-In this article, we have built a really simple Copilot plugin for Milkdown.
-The plugin is not perfect, but it's a good start to help you build your own.
-
-The source code is available on [Milkdown/examples/vanilla-openapi](https://github.com/Milkdown/examples/tree/main/vanilla-openai).
-I hope it can give you some inspiration.

-# Introducing Milkdown@7
-
-It's been almost one year since the release of [milkdown](https://milkdown.dev) V6.
-It helped a lot of users to build their own markdown based applications.
-It has 13k downloads per month and I feel so grateful that users like that.
-
-However, we noticed that there're some problems cannot be resolved if we don't make a new major version.
-What big changes did we made? I'll introduce them to you in this blog.
-
-## TL;DR
-
-- The editor becomes a first-class headless component.
-
-- Factory plugins are fully replaced by **composable plugins**.
-
-- Runtime plugin toggling is supported.
-
-- Universal widget plugins.
-
-- Better Vue and React support.
-
-- API documentation is provided.
-
-## Why Headless?
-
-In the past, milkdown had a lot of internal styles to make sure the editor can work out of box and the themes are easy to create.
-However, I found it limits the users to design their own editor.
-Even worse, if you have an well designed application,
-it is really hard to keep the style of the milkdown editor same with the rest of the application.
-You'll need to override lots of styles everywhere.
-It stops a log of users from using milkdown.
-
-If we think about why users need an editor,
-the most important thing is always the functionality of the editor.
-Users just want a component that can provide smooth editing experience.
-Style will always be the second thing.
-
-So, why not remove all the internal styles and make the editor a headless component?
-The users can easily integrate the editor into their own application.
-They can use their own styles and even use their own components to render the editor.
-We just care about the functionality of the editor. Make sure it works well.
-
-## Composable Plugins
-
-Although the composable plugins have been existed in milkdown for a long time,
-we use factory plugins to create most of the official plugins in V6.
-
-But, the problem is that factory plugins limit the possibility of the plugins.
-The factory plugins handle a bunch of complex logic and it is hard to extend.
-So for users who want to create a plugin in a easy way, they must follow the factory plugin's way.
-
-```ts
-const nodePlugin = createPlugin(() => ({
-    id: 'node',
-    schema: someSchema,
-    inputRules: someInputRules
-    commands: someCommands
-}))
-```
-
-See? You can define a lot of things inside the factory plugin.
-But if you want to use some part of them in another plugin, it's really hard to do that.
-
-However, the milkdown's plugin system is designed to be flexible and composable.
-We want to let users to control the data flow entirely.
-
-So, we decided to remove all the factory plugins and use composable plugins to replace them.
-The composable plugins can keep the atomicity of the plugins and make the plugin system more flexible.
-They also make the plugin system easier to maintain.
-
-```ts
-const nodeSchema = $node("node", someSchema);
-const nodeInputRules = $inputRules(someInputRules);
-const nodeCommands = $commands(someCommands);
-```
-
-If you want to reuse them, it also will be very easy.
-
-```ts
-const anotherCommand = $commands(() => {
-  return setBlockType(nodeSchema.type());
-});
-```
-
-## Runtime Plugin Toggling
-
-In the past, once you register a plugin, you cannot remove it.
-In V7, we support runtime plugin toggling by providing two new API: `editor.remove` and `editor.removeConfig`.
-They can let users remove the plugins and configs at runtime.
-
-```ts
-import { Editor } from "@milkdown/core";
-import { someMilkdownPlugin } from "some-milkdown-plugin";
-
-const editor = await Editor.config(configForPlugin)
-  .use(someMilkdownPlugin)
-  .create();
-
-// remove plugin
-await editor.remove(someMilkdownPlugin);
-
-// remove config
-editor.removeConfig(configForPlugin);
-
-// add another plugin
-editor.use(anotherMilkdownPlugin);
-
-// Recreate the editor to apply changes.
-await editor.create();
-```
-
-Also, if you call the `editor.create` method after the editor is created,
-it will recreate the editor and apply all the changes.
-
-## Universal Widget Plugins
-
-We have 4 official widget plugins in V6: _slash_, _tooltip_, _block_ and _menu_.
-
-They are all well designed and easy to use.
-But if you want to customize them, what you can do is really limited.
-Also, it's hard to reuse their logic even if you want to create something similar to them.
-For example, if you want to create a mention plugin which will show a list of users when you type `@`,
-you need to create a new plugin from scratch.
-
-So, in V7, we make _slash_, _tooltip_ and _block_ plugins universal.
-You can use them to build you features easily.
-For example, if you want to create a mention plugin, you can use the new slash plugin to do that.
-Another example is that you can also create tooltips for different types of nodes.
-Display a tooltip with input when you focus on an image node, or display a tooltip with buttons when you select some text.
-
-What about the _menu_ plugin? We removed it because we think it's easy to create a menu plugin by yourself.
-We've already done that in the [official playground](https://milkdown.dev/playground).
-And, trust me, [it won't need much code](https://github.com/milkdown/website/blob/main/src/component/Playground/Milkdown/index.tsx#L57).
-
-## Better Vue and React Support
-
-Thanks to the [Saul-Mirone/prosemirror-adapter project](https://github.com/Saul-Mirone/prosemirror-adapter).
-In milkdown V7. We allow users to use vue and react to render lots of parts of the editor.
-For example, you can use them to render your own code block, drag handle or even small icons.
-

-
-## API Documentation
-
-What's the hardest thing to do when maintaining an open source project?
-Keep the documentation up to date.
-Thanks to the [marijnh/builddocs project](https://github.com/marijnh/builddocs),
-we can generate the API documentation automatically from the source code.
-
-We also redesigned the documentation website, provide a more powerful playground and lots of examples.

-# Understanding Headless Slash Plugin
-
-In the old Milkdown versions. The slash plugin can be used to display a list of commands when users type `/` in the editor.
-It provides a way to insert nodes and commands into the editor, and it's really easy to use.
-
-![legacy slash plugin](/blogs/understanding-headless-slash-plugin/legacy-slash-plugin.png)
-
-However, it's hard to extend the slash plugin to support more commands, or if you want to change the UI of the slash plugin, you have to rewrite the whole plugin.
-But, write a new plugin is always a hard work. You have to understand a lot of context and APIs of both ProseMirror and Milkdown.
-
-## User Story
-
-So, why don't we provide the slash plugin as a headless plugin?
-In most cases, developers just want to make sure that when users type a special character, a dropdown menu will be displayed.
-But the trigger character and the UI of the dropdown menu are different in different cases.
-
-For example:
-
-- When user type `/`, the menu contains a list of **commands**.
-- When user type `:`, the menu contains a list of **emoji**.
-- When user type `@`, the menu contains a list of **users**.
-
-That's the story behind the headless slash plugin. We provide the plugin to solve a single problem: **display a dropdown menu when users input satisfy a condition**.
-
-## How to use
-
-In the new slash plugin, you'll need to control when to display the dropdown menu by yourself.
-And you'll also need to provide the UI of the dropdown menu.
-So, you'll need to create a `SlashProvider` instance.
-
-```ts
-import { slashPlugin, SlashProvider } from "@milkdown/plugin-slash";
-
-const slashProvider = new SlashProvider({
-  content: YourDropdownUI,
-  shouldShow(this: SlashProvider, view: EditorView) {
-    const currentText = this.getContent(view);
-
-    if (currentText === "") {
-      return false;
-    }
-
-    // Display the menu if the last character is `/`.
-    if (currentText.endsWith("/")) {
-      return true;
-    }
-
-    return false;
-  },
-});
-```
-
-Then, you can use the slash provider in your plugin view.
-
-```ts
-import { EditorState } from "@milkdown/prose/state";
-import { EditorView, PluginView } from "@milkdown/prose/view";
-
-function yourSlashView(): PluginView {
-  return {
-    update: (view: EditorView, prevState: EditorState) => {
-      slashProvider.update(view, prevState);
-    },
-    destroy: () => {
-      slashProvider.destroy();
-    },
-  };
-}
-```
-
-Last, you'll need to add the slash plugin to your editor.
-
-```ts
-import { Editor } from "@milkdown/core";
-import { slashFactory } from "@milkdown/plugin-slash";
-
-const slash = slashFactory("my-slash");
-
-Editor.make()
-  .config((ctx) => {
-    ctx.set(slash.key, {
-      view: slashPluginView,
-    });
-  })
-  .use(slash)
-  .create();
-```
-
-## Use with Prosemirror Adapter
-
-If you're using milkdown with UI frameworks like React,
-I recommend you to use the [Prosemirror Adapter](https://github.com/Saul-Mirone/prosemirror-adapter).
-It can help you build prosemirror UI components with your favorite UI framework.
-
-For example, if you're using React:
-
-```tsx
-import { SlashProvider } from "@milkdown/plugin-slash";
-import { useInstance } from "@milkdown/react";
-import { usePluginViewContext } from "@prosemirror-adapter/react";
-
-export const DropdownMenu = () => {
-  const { view, prevState } = usePluginViewContext();
-  const slashProvider = useRef<SlashProvider>();
-  const divRef = useRef<HTMLDivElement>(null);
-  const [loading] = useInstance();
-
-  useEffect(() => {
-    if (!ref.current || loading) return;
-
-    slashProvider.current ??= new SlashProvider({
-      content: divRef.current,
-      // ...
-    });
-
-    return () => {
-      slashProvider.current?.destroy();
-      slashProvider.current = undefined;
-    };
-  }, [loading, root, setOpened, setSearch, setSelected]);
-
-  useEffect(() => {
-    slashProvider.current?.update(view, prevState);
-  });
-
-  // Add a wrapper `div` to hide the dropdown menu when initializing.
-  return (
-    <div className="hidden">
-      <div role="tooltip" ref={divRef}>
-        <h1>Hi! I'm a dropdown menu.</h1>
-      </div>
-    </div>
-  );
-};
-```
-
-And in your editor component:
-
-```ts
-import { usePluginViewFactory } from "@prosemirror-adapter/react";
-
-export const YourEditor = () => {
-  const pluginViewFactory = usePluginViewFactory();
-
-  useEditor((editor) => {
-    return Editor.make()
-      .config((ctx) => {
-        ctx.set(slash.key, {
-          view: pluginViewFactory({
-            component: DopdownMenu,
-          }),
-        });
-      })
-      .use(slash);
-  });
-
-  // ...
-};
-```
-
-## Real World Example
-
-In [milkdown playground](/playground), you can type `/` to display a dropdown menu.
-
-![command dropdown](/blogs/understanding-headless-slash-plugin/command-dropdown.png)
-
-You can also type `:(\S)+` (for example: `:mil`) to display a list of emojis.
-
-![emoji dropdown](/blogs/understanding-headless-slash-plugin/emoji-dropdown.png)
-
-You can find the source code of them in [Milkdown website](https://github.com/Milkdown/website).
-I hope you enjoy the new slash plugin.

-# Architecture Overview
-
-Milkdown is built with a modular, layered architecture that provides flexibility and extensibility. This document explains the core architectural concepts and how they work together.
-
-![0.75](/guide/milkdown-architecture.png "Milkdown Architecture")
-
-## Core Architecture Layers
-
-Milkdown's architecture is built upon four distinct layers, each providing specific functionality and extensibility:
-
-### 🥛 Core Layer
-
-The foundation of Milkdown that provides:
-
-- Plugin loading and management system
-- Core editor concepts and interfaces
-- Base document model integration
-- Essential utilities and helpers
-
-### 🧇 Plugin Layer
-
-A comprehensive collection of modular plugins that extend the editor's functionality:
-
-- Syntax plugins (Markdown parsing, GFM, etc.)
-- UI plugins (toolbar, menu, etc.)
-- Feature plugins (image upload, table, etc.)
-- Utility plugins (history, clipboard, etc.)
-
-### 🍮 Component Layer
-
-Headless UI components that serve as building blocks:
-
-- Toolbar components
-- Slash menu components
-- Table components
-
-### 🍰 Editor Layer
-
-Ready-to-use, user-friendly editors:
-
-- Crepe editor
-- Custom editor implementations
-
-## Architecture Benefits
-
-This layered approach provides several key benefits:
-
-1. **Modularity**: Each layer can be used independently
-2. **Flexibility**: Mix and match components as needed
-3. **Extensibility**: Create custom implementations at any layer
-4. **Maintainability**: Clear separation of concerns
-5. **Reusability**: Components can be shared across implementations
-
-## Markdown Transformation
-
-![0.75](/guide/transformer.png "Transformer")
-
-Milkdown's transformation system handles the conversion between Markdown and the editor's internal document model:
-
-### Parsing Process
-
-1. Markdown text → Remark AST
-2. Remark AST → ProseMirror Schema
-3. Schema → ProseMirror Document
-
-### Serialization Process
-
-1. ProseMirror Document → ProseMirror Schema
-2. Schema → Remark AST
-3. Remark AST → Markdown text
-
-This transformation system ensures:
-
-- Accurate Markdown parsing
-- Consistent document structure
-- Reliable serialization
-- Extensible transformation pipeline
-
-## Context System
-
-The Context System is a powerful state management and dependency coordination system that enables plugins to work together seamlessly.
-
-![1.00](/guide/plugin-sequence.png "Plugin Sequence")
-
-### Core Concepts
-
-#### 1. Context (Ctx)
-
-The main interface for plugins to interact with the system:
-
-```typescript
-interface Ctx {
-  get: <T>(slice: Slice<T>) => T;
-  set: <T>(slice: Slice<T>, value: T) => void;
-  wait: (timer: Timer) => Promise<void>;
-  done: (timer: Timer) => void;
-  inject: <T>(slice: Slice<T>, value: T) => void;
-  remove: <T>(slice: Slice<T>) => void;
-}
-```
-
-#### 2. Slices
-
-State containers that can be shared between plugins:
-
-```typescript
-// Create a slice with initial value and name
-const themeSlice = createSlice("light", "theme");
-
-// Use in a plugin
-const themePlugin: MilkdownPlugin = (ctx) => {
-  return () => {
-    // Read current theme
-    const theme = ctx.get(themeSlice);
-
-    // Update theme
-    ctx.set(themeSlice, "dark");
-
-    // React to theme changes
-    ctx.watch(themeSlice, (newTheme) => {
-      // Handle theme change
-    });
-  };
-};
-```
-
-#### 3. Timers
-
-Dependency management system for plugin coordination:
-
-```typescript
-// Define a timer
-const dataReady = createTimer("DataReady");
-
-// Use in a plugin
-const dataPlugin: MilkdownPlugin = (ctx) => {
-  ctx.record(dataReady);
-
-  return async () => {
-    // Wait for dependencies
-    await ctx.wait(SchemaReady);
-
-    // Do work
-    // ...
-
-    // Mark as ready
-    ctx.done(dataReady);
-  };
-};
-```
-
-### Plugin Lifecycle
-
-Plugins follow a consistent lifecycle pattern:
-
-```typescript
-const examplePlugin: MilkdownPlugin = (ctx) => {
-  // 1. Setup Phase
-  ctx.inject(mySlice, defaultValue);
-  ctx.record(myTimer);
-
-  return async () => {
-    // 2. Initialization Phase
-    await ctx.wait(RequiredTimer);
-
-    // 3. Runtime Phase
-    const value = ctx.get(mySlice);
-    ctx.set(mySlice, newValue);
-
-    // 4. Cleanup Phase
-    return () => {
-      ctx.remove(mySlice);
-    };
-  };
-};
-```
-
-### Best Practices
-
-1. **State Management**
-   - Use slices for shared state
-   - Keep state minimal and focused
-   - Watch for state changes when needed
-
-2. **Dependency Management**
-   - Use timers for coordination
-   - Wait for required dependencies
-   - Mark completion appropriately
-
-3. **Plugin Organization**
-   - Follow the lifecycle pattern
-   - Clean up resources properly
-   - Document dependencies clearly

-# Code Highlighting
-
-Milkdown supports syntax highlighting for code blocks through the `@milkdown/plugin-highlight` plugin. This plugin provides several options for highlighting code with different syntax highlighters.
-
-## Installation
-
-```bash
-npm install @milkdown/plugin-highlight
-```
-
-## Basic Usage
-
-The highlight plugin requires a parser to be configured. Here's a basic example using the Shiki parser:
-
-```typescript
-import { Editor } from "@milkdown/core";
-import { commonmark } from "@milkdown/preset-commonmark";
-import { highlight, highlightPluginConfig } from "@milkdown/plugin-highlight";
-import { createParser } from "@milkdown/plugin-highlight/shiki";
-
-const editor = Editor.make()
-  .config(async (ctx) => {
-    const parser = await createParser({
-      theme: "github-light",
-      langs: ["javascript", "typescript", "python", "html", "css"],
-    });
-    ctx.set(highlightPluginConfig.key, { parser });
-  })
-  .use(commonmark)
-  .use(highlight)
-  .create();
-```
-
-## Available Parsers
-
-The plugin supports multiple syntax highlighting libraries:
-
-### Shiki
-
-Provides high-quality syntax highlighting with VS Code themes. Learn more at [Shiki](https://shiki.style/):
-
-```typescript
-import { createParser } from "@milkdown/plugin-highlight/shiki";
-
-const parser = await createParser({
-  theme: "github-light",
-  langs: ["javascript", "typescript", "python"],
-});
-ctx.set(highlightPluginConfig.key, { parser });
-```
-
-### Lowlight
-
-Based on [highlight.js](https://highlightjs.org/), supports many languages:
-
-```typescript
-import { createParser } from "@milkdown/plugin-highlight/lowlight";
-import { common } from "lowlight";
-
-const parser = createParser({ common });
-ctx.set(highlightPluginConfig.key, { parser });
-```
-
-Learn more about Lowlight at [lowlight](https://github.com/wooorm/lowlight).

-### Refractor
-
-Based on [Prism.js](https://prismjs.com/):
-
-```typescript
-import { createParser } from "@milkdown/plugin-highlight/refractor";
-import { refractor } from "refractor";
-
-const parser = createParser({ refractor });
-ctx.set(highlightPluginConfig.key, { parser });

-A lightweight and fast syntax highlighter. Learn more at [Sugar High](https://github.com/huozhi/sugar-high):
-
-```typescript
-import { createParser } from "@milkdown/plugin-highlight/sugar-high";
-
-const parser = createParser();
-ctx.set(highlightPluginConfig.key, { parser });
-```
-
-## Styling
-
-The highlighted code will have CSS classes applied based on the chosen parser. You'll need to include appropriate CSS to style the highlighted tokens.
-
-### Sugar High Classes
-
-Sugar High uses classes like:
-
-- `sh__token--identifier`
-- `sh__token--string`
-- `sh__token--keyword`
-- `sh__token--sign`
-- `sh__token--property`
-
-You can style these using CSS variables:
-
-```css
-.sh__token--identifier {
-  color: var(--sh-identifier);
-}
-.sh__token--string {
-  color: var(--sh-string);
-}
-.sh__token--keyword {
-  color: var(--sh-keyword);
-}
-```
-
-### Other Parsers
-
-For Lowlight, Refractor, and Shiki, refer to their respective documentation for styling information.
-
-## Example
-
-Here's a complete example with Shiki:
-
-```typescript
-import { Editor } from "@milkdown/core";
-import { commonmark } from "@milkdown/preset-commonmark";
-import { highlight, highlightPluginConfig } from "@milkdown/plugin-highlight";
-import { createParser } from "@milkdown/plugin-highlight/shiki";
-
-async function createHighlightedEditor() {
-  const parser = await createParser({
-    theme: "github-light",
-    langs: ["javascript", "typescript", "python", "html", "css", "json"],
-  });
-
-  const editor = Editor.make()
-    .config((ctx) => {
-      ctx.set(highlightPluginConfig.key, { parser });
-    })
-    .use(commonmark)
-    .use(highlight);
-
-  await editor.create();
-  return editor;
-}
-```
-
-With this setup, your code blocks will be automatically highlighted:
-
-````markdown
-```javascript
-console.log("Hello, world!");
-const greeting = (name) => `Hello, ${name}!`;
-```
-````
-
-The code above will render with syntax highlighting applied to keywords, strings, and other language constructs.

-# Collaborative Editing
-
-Milkdown supports collaborative editing powered by [Y.js](https://docs.yjs.dev/).
-We provide the [@milkdown/plugin-collab](/docs/api/plugin-collab) plugin to help you use milkdown with yjs easily.
-This plugin includes basic collaborative editing features like:
-
-- Sync between clients.
-- Remote cursor support.
-- Undo/Redo support.
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/vanilla-collab"}
-
-## Configure Plugin
-
-First you need to install the plugin and yjs through npm:
-
-```bash
-npm install @milkdown/plugin-collab
-
-npm install yjs y-protocols y-prosemirror
-```
-
-And you also need to choose a [provider for yjs](https://docs.yjs.dev/ecosystem/connection-provider), here we use [y-websocket](https://docs.yjs.dev/ecosystem/connection-provider/y-websocket) as an example.
-
-After the installation, you can configure your editor:
-
-```typescript
-// ...import other plugins
-import { collab, collabServiceCtx } from "@milkdown/plugin-collab";
-
-async function setup() {
-  const editor = await Editor.make()
-    .config(nord)
-    .use(commonmark)
-    .use(collab)
-    .create();
-
-  const doc = new Doc();
-  const wsProvider = new WebsocketProvider("<YOUR_WS_HOST>", "milkdown", doc);
-
-  editor.action((ctx) => {
-    const collabService = ctx.get(collabServiceCtx);
-
-    collabService
-      // bind doc and awareness
-      .bindDoc(doc)
-      .setAwareness(wsProvider.awareness)
-      // connect yjs with milkdown
-      .connect();
-  });
-}
-```
-
-Now your editor can support collaborative editing. Isn't it easy?
-
-## Connect and Disconnect
-
-You may want to control the connect status of the editor manually.
-
-```typescript
-editor.action((ctx) => {
-  const collabService = ctx.get(collabServiceCtx);
-  const doc = new Doc();
-  const wsProvider = new WebsocketProvider("<YOUR_WS_HOST>", "milkdown", doc);
-
-  collabService.bindDoc(doc).setAwareness(wsProvider.awareness);
-
-  document.getElementById("connect").onclick = () => {
-    wsProvider.connect();
-    collabService.connect();
-  };
-
-  document.getElementById("disconnect").onclick = () => {
-    wsProvider.disconnect();
-    collabService.disconnect();
-  };
-});
-```
-
-## Default Template
-
-By default, the editor will show a empty document. You may want to use a template to show a document.
-
-```typescript
-const template = `# Heading`;
-
-editor.action((ctx) => {
-  const collabService = ctx.get(collabServiceCtx);
-  const doc = new Doc();
-  const wsProvider = new WebsocketProvider("<YOUR_WS_HOST>", "milkdown", doc);
-
-  collabService.bindDoc(doc).setAwareness(wsProvider.awareness);
-
-  wsProvider.once("synced", async (isSynced: boolean) => {
-    if (isSynced) {
-      collabService
-        // apply your template
-        .applyTemplate(markdown)
-        // don't forget connect
-        .connect();
-    }
-  });
-});
-```
-
-Keep in mind that applying a template multiple times may cause some unexpected behavior, such as duplicate content.
-Because of this you need to make sure **the template is applied only once**.
-
-By default, the template will only be applied if _document get from remote server is empty_.
-You can control this behavior through passing second parameter to `applyTemplate`:
-
-```typescript
-collabService
-  .applyTemplate(markdown, (remoteNode, templateNode) => {
-    // return true to apply template
-  })
-  // don't forget connect
-  .connect();
-```
-
-Here the nodes we get are [prosemirror nodes](https://prosemirror.net/docs/ref/#model.Node).
-You should return `true` if the template should be applied, and `false` if not.

-# Commands
-
-Commands are a powerful way to programmatically modify editor content. The command system in Milkdown provides a flexible and type-safe way to create, manage, and execute commands.
-
-## Command Manager
-
----
-
-The command manager is the central place for handling all editor commands. It provides methods to:
-
-- Register new commands
-- Execute commands
-- Chain multiple commands together
-- Handle command arguments
-
-## Run a Command
-
----
-
-You can execute commands using the command manager through the editor's action system:
-
-```typescript
-import { Editor, commandsCtx } from "@milkdown/kit/core";
-import {
-  commonmark,
-  toggleEmphasisCommand,
-} from "@milkdown/kit/preset/commonmark";
-
-async function setup() {
-  const editor = await Editor.make().use(commonmark).create();
-
-  const toggleItalic = () =>
-    editor.action((ctx) => {
-      // get command manager
-      const commandManager = ctx.get(commandsCtx);
-
-      // call command
-      commandManager.call(toggleEmphasisCommand.key);
-    });
-
-  // get markdown string:
-  $button.onClick = toggleItalic;
-}
-```
-
-## Command Chaining
-
----
-
-You can chain multiple commands together using the command manager's `chain` method. Commands in the chain will be executed in order until one of them returns `true`:
-
-```typescript
-import { Editor, commandsCtx } from "@milkdown/kit/core";
-import {
-  commonmark,
-  toggleEmphasisCommand,
-  toggleStrongCommand,
-} from "@milkdown/kit/preset/commonmark";
-
-const editor = await Editor.make().use(commonmark).create();
-
-editor.action((ctx) => {
-  const commandManager = ctx.get(commandsCtx);
-
-  // Chain multiple commands
-  commandManager
-    .chain()
-    .pipe(toggleEmphasisCommand.key) // Try to toggle emphasis
-    .pipe(toggleStrongCommand.key) // If emphasis fails, try to toggle strong
-    .run();
-});
-```
-
-You can also mix inline commands with registered commands:
-
-```typescript
-import { chainCommands } from "@milkdown/prose/commands";
-
-editor.action((ctx) => {
-  const commandManager = ctx.get(commandsCtx);
-
-  commandManager
-    .chain()
-    .inline(someInlineCommand) // Add an inline command
-    .pipe(toggleEmphasisCommand.key) // Add a registered command
-    .run();
-});
-```
-
-## Create a Command
-
----
-
-To create a command, use the `$command` utility from `@milkdown/utils`. Commands should be [prosemirror commands](https://prosemirror.net/docs/guide/#commands).
-
-### Example: Command without argument
-
-```typescript
-import { Editor } from "@milkdown/kit/core";
-import { blockquoteSchema } from "@milkdown/kit/preset/commonmark";
-import { wrapIn } from "@milkdown/kit/prose/commands";
-import { $command, callCommand } from "@milkdown/kit/utils";
-
-const wrapInBlockquoteCommand = $command(
-  "WrapInBlockquote",
-  (ctx) => () => wrapIn(blockquoteSchema.type(ctx)),
-);
-
-// register the command when creating the editor
-const editor = Editor().make().use(wrapInBlockquoteCommand).create();
-
-// call command
-editor.action(callCommand(wrapInBlockquoteCommand.key));
-```
-
-### Example: Command with argument
-
-Commands can accept arguments of any type:
-
-```typescript
-import { headingSchema } from "@milkdown/kit/preset/commonmark";
-import { setBlockType } from "@milkdown/kit/prose/commands";
-import { $command, callCommand } from "@milkdown/kit/utils";
-
-// use number as the type of argument
-export const WrapInHeading = createCmdKey<number>();
-const wrapInHeadingCommand = $command(
-  "WrapInHeading",
-  (ctx) =>
-    (level = 1) =>
-      setBlockType(headingSchema.type(ctx), { level }),
-);
-
-// call command
-editor.action(callCommand(wrapInHeadingCommand.key)); // turn to h1 by default
-editor.action(callCommand(wrapInHeadingCommand.key, 2)); // turn to h2
-```
-
-### Example: Command with Multiple Arguments
-
-```typescript
-interface TableConfig {
-  rows: number;
-  cols: number;
-  withHeader: boolean;
-}
-
-const insertTableCommand = $command(
-  "InsertTable",
-  (ctx) => (config: TableConfig) => {
-    // Implementation for inserting a table
-    return (state, dispatch) => {
-      // ... table insertion logic
-      return true;
-    };
-  },
-);
-
-// Usage
-editor.action(
-  callCommand(insertTableCommand.key, {
-    rows: 3,
-    cols: 3,
-    withHeader: true,
-  }),
-);
-```
-
-## Best Practices
-
----
-
-1. **Command Naming**
-   - Use clear, descriptive names
-   - Follow the pattern: `[Action][Target]Command`
-   - Example: `toggleEmphasisCommand`, `insertTableCommand`
-
-2. **Command Organization**
-   - Group related commands together
-   - Use namespaces for command keys
-   - Keep commands focused and single-purpose
-
-3. **Error Handling**
-   - Always check if the command can be executed
-   - Return `false` if the command cannot be executed
-   - Handle edge cases gracefully
-
-4. **Performance**
-   - Keep commands lightweight
-   - Avoid unnecessary state updates
-   - Use command chaining for complex operations
-
-5. **Type Safety**
-   - Use TypeScript for command arguments
-   - Define clear interfaces for command payloads
-   - Use generics for type-safe command keys
-
-## Common Patterns
-
----
-
-### Toggle Commands
-
-```typescript
-const toggleCommand = $command(
-  "ToggleFeature",
-  (ctx) => () => (state, dispatch) => {
-    const isActive = checkIfActive(state);
-    return isActive
-      ? removeFeature(state, dispatch)
-      : addFeature(state, dispatch);
-  },
-);
-```
-
-### Insert Commands
-
-```typescript
-const insertCommand = $command(
-  "InsertContent",
-  (ctx) => (content: string) => (state, dispatch) => {
-    const { selection } = state;
-    if (!selection) return false;
-
-    const tr = state.tr.insertText(content, selection.from);
-    dispatch?.(tr);
-    return true;
-  },
-);
-```
-
-### Transform Commands
-
-```typescript
-const transformCommand = $command(
-  "TransformContent",
-  (ctx) => (transform: (node: ProseNode) => ProseNode) => (state, dispatch) => {
-    const { selection } = state;
-    if (!selection) return false;
-
-    const tr = state.tr.replaceWith(
-      selection.from,
-      selection.to,
-      transform(state.doc.nodeAt(selection.from)!),
-    );
-    dispatch?.(tr);
-    return true;
-  },
-);
-```

-- [Prosemirror](https://prosemirror.net/) - A toolkit for building rich-text editors on the web
-- [Remark](https://github.com/remarkjs/remark) - Markdown parser done right
-- [TypeScript](https://www.typescriptlang.org/) - For type safety and better developer experience
-
-## Creating Your First Editor
-
-Milkdown provides two distinct approaches to create an editor, each suited for different needs:
-
-### 1. 🍼 Using `@milkdown/kit` (Build from Scratch)
-
-This approach gives you complete control over your editor. Use this if you want to:
-
-- Build a custom editor from the ground up
-- Have full control over which features to include
-- Create a highly customized editing experience
-- Integrate with specific frameworks or requirements
-
-First, install the required packages:
-
-```bash
-npm install @milkdown/kit
-```
-
-Create a basic editor with commonmark syntax:
-
-```typescript
-import { Editor } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-// This is the must have css for prosemirror
-import "@milkdown/kit/prose/view/style/prosemirror.css";
-
-Editor.make().use(commonmark).create();
-```
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/vanilla-commonmark"}
-
-Add undo & redo support:
-
-```typescript
-import { Editor } from "@milkdown/kit/core";
-import { history } from "@milkdown/kit/plugin/history";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-import { nord } from "@milkdown/theme-nord";
-import "@milkdown/theme-nord/style.css";
-
-const milkdown = Editor.make()
-  .config(nord)
-  .use(commonmark)
-  .use(history)
-  .create()
-  .then(() => {
-    console.log("Editor created");
-  });
-
-// To destroy the editor
-milkdown.destroy();
-```
-
-> **Note**: `<Mod>` is `<Cmd>` for macOS and `<Ctrl>` for other platforms.
-
-### 2. 🥞 Using `@milkdown/crepe` (Ready to Use)
-
-This is the quickest way to get started with a fully-featured editor. Use this if you want to:
-
-- Get up and running quickly
-- Have a well-designed editor out of the box
-- Focus on content rather than configuration
-- Have a production-ready solution with minimal setup
-
-```bash
-npm install @milkdown/crepe
-```
-
-```typescript
-import { Crepe } from "@milkdown/crepe";
-import "@milkdown/crepe/theme/common/style.css";
-/**
- * Available themes:
- * frame, classic, nord
- * frame-dark, classic-dark, nord-dark
- */
-import "@milkdown/crepe/theme/frame.css";
-
-const crepe = new Crepe({
-  root: "#app",
-  defaultValue: "Hello, Milkdown!",
-});
-
-crepe.create().then(() => {
-  console.log("Editor created");
-});
-
-// To destroy the editor
-crepe.destroy();
-```

-# Interacting with Editor
-
-This guide covers the essential ways to interact with the Milkdown editor, including initialization, content management, and editor lifecycle.
-
-## Using Crepe Editor
-
----
-
-Crepe is a high-level wrapper around Milkdown that provides a simpler API for common editor operations. Here's how to use it:
-
-```typescript
-import { Crepe } from "@milkdown/crepe";
-
-// Create a new editor instance
-const editor = new Crepe({
-  // Optional: specify root element (DOM node or selector)
-  root: "#editor",
-
-  // Optional: set default content, supports markdown, json and dom.
-  defaultValue: "# Hello Crepe!",
-});
-
-// Create the editor
-await editor.create();
-
-// Get markdown content
-const markdown = editor.getMarkdown();
-
-// Set readonly mode
-editor.setReadonly(true);
-
-// Register event listeners
-editor.on((listener) => {
-  listener.markdownUpdated((ctx, markdown) => {
-    console.log("Content updated:", markdown);
-  });
-
-  listener.focus((ctx) => {
-    console.log("Editor focused");
-  });
-
-  listener.blur((ctx) => {
-    console.log("Editor blurred");
-  });
-
-  listener.selectionUpdated((ctx, selection, prevSelection) => {
-    console.log("Selection updated:", selection);
-  });
-
-  listener.updated((ctx, doc, prevDoc) => {
-    console.log("Document updated:", doc);
-  });
-});
-
-// Destroy the editor when done
-await editor.destroy();
-```
-
-## Register to DOM
-
----
-
-By default, milkdown will create editor on the `document.body`. Alternatively, you can also point out which dom node you want it to load into:
-
-```typescript
-import { rootCtx } from "@milkdown/kit/core";
-
-Editor.make().config((ctx) => {
-  ctx.set(rootCtx, document.querySelector("#editor"));
-});
-```
-
-It's also possible to just pass a selector to `rootCtx`:
-
-> The selector will be passed to `document.querySelector` to get the dom.
-
-```typescript
-import { rootCtx } from "@milkdown/kit/core";
-
-Editor.make().config((ctx) => {
-  ctx.set(rootCtx, "#editor");
-});
-```
-
-## Setting Default Value
-
----
-
-We support three types of default values:
-
-- Markdown strings
-- HTML DOM
-- Prosemirror documentation JSON
-
-### Markdown
-
-You can set a markdown string as the default value of the editor.
-
-```typescript
-import { defaultValueCtx } from "@milkdown/kit/core";
-
-const defaultValue = "# Hello milkdown";
-Editor.make().config((ctx) => {
-  ctx.set(defaultValueCtx, defaultValue);
-});
-```
-
-### Dom
-
-You can also use HTML as default value.
-
-Let's assume that we have the following html snippets:
-
-```html
-<div id="pre">
-  <h1>Hello milkdown!</h1>
-</div>
-```
-
-Then we can use it as a defaultValue with a `type` specification:
-
-```typescript
-import { defaultValueCtx } from "@milkdown/kit/core";
-
-const defaultValue = {
-  type: "html",
-  dom: document.querySelector("#pre"),
-};
-Editor.make().config((ctx) => {
-  ctx.set(defaultValueCtx, defaultValue);
-});
-```
-
-### JSON
-
-We can also use a JSON object as a default value.
-
-This JSON object can be obtained by a listener through the [listener-plugin](https://www.npmjs.com/package/@milkdown/plugin-listener), for example:
-
-```typescript
-import { listener, listenerCtx } from "@milkdown/kit/plugin/listener";
-
-let jsonOutput;
-
-Editor.make()
-  .config((ctx) => {
-    ctx.get(listenerCtx).updated((ctx, doc, prevDoc) => {
-      jsonOutput = doc.toJSON();
-    });
-  })
-  .use(listener);
-```
-
-Then we can use this `jsonOutput` as default Value:
-
-```typescript
-import { defaultValueCtx } from "@milkdown/kit/core";
-
-const defaultValue = {
-  type: "json",
-  value: jsonOutput,
-};
-Editor.make().config((ctx) => {
-  ctx.set(defaultValueCtx, defaultValue);
-});
-```
-
-## Inspecting Editor Status
-
----
-
-You can inspect the editor's status through the `status` property.
-
-```typescript
-import { Editor, EditorStatus } from "@milkdown/kit/core";
-
-const editor = Editor.make().use(/* some plugins */);
-
-assert(editor.status === EditorStatus.Idle);
-
-editor.create().then(() => {
-  assert(editor.status === EditorStatus.Created);
-});
-
-assert(editor.status === EditorStatus.OnCreate);
-
-editor.destroy().then(() => {
-  assert(editor.status === EditorStatus.Destroyed);
-});
-
-assert(editor.status === EditorStatus.OnDestroyed);
-```
-
-You can also listen to the status changes:
-
-```typescript
-import { Editor, EditorStatus } from "@milkdown/kit/core";
-
-const editor = Editor.make().use(/* some plugins */);
-
-editor.onStatusChange((status: EditorStatus) => {
-  console.log(status);
-});
-```
-
-### Status Lifecycle
-
-1. `Idle`: Initial state
-2. `OnCreate`: During creation
-3. `Created`: Successfully created
-4. `OnDestroyed`: During destruction
-5. `Destroyed`: Successfully destroyed
-

----
-
-As mentioned above, you can add a listener to the editor, in order to get its value when needed.
-You can add as many listeners as you want, all the listeners will be triggered at once.
-
-### Markdown Listener
-
-You can add markdown listener to get the editor's contents as a markdown string.
-
-> ⚠️ Markdown listener will influence the performance for large documents, please use it carefully.
-> If you have a large document, I suggest you to only `parse` and `serialize` the document when needed.
-
-```typescript
-import { listener, listenerCtx } from "@milkdown/kit/plugin/listener";
-
-let output = "";
-
-Editor.make()
-  .config((ctx) => {
-    ctx.get(listenerCtx).markdownUpdated((ctx, markdown, prevMarkdown) => {
-      output = markdown;
-    });
-  })
-  .use(listener);
-```
-
-### Doc Listener
-
-You can also listen to the [raw prosemirror document node](https://prosemirror.net/docs/ref/#model.Node), and do things you want from there.
-
-```typescript
-import { listener, listenerCtx } from "@milkdown/kit/plugin/listener";
-
-let jsonOutput;
-
-Editor.make()
-  .config((ctx) => {
-    ctx.get(listenerCtx).updated((ctx, doc, prevDoc) => {
-      jsonOutput = doc.toJSON();
-    });
-  })
-  .use(listener);
-```
-
-### Selection Listener
-
-You can track changes to the editor's selection using the `selectionUpdated` event. This is useful for implementing features like:
-
-- Custom toolbars that update based on selection
-- Context menus
-- Selection-based formatting controls
-
-```typescript
-import { listener, listenerCtx } from "@milkdown/kit/plugin/listener";
-import { Selection, TextSelection } from "@milkdown/prose/state";
-
-Editor.make()
-  .config((ctx) => {
-    ctx.get(listenerCtx).selectionUpdated((ctx, selection, prevSelection) => {
-      if (selection instanceof TextSelection) {
-        // Get selection range
-        const { from, to } = selection;
-
-        // Example: Update toolbar based on selection
-        updateToolbar({
-          hasSelection: from !== to,
-          selectionStart: from,
-          selectionEnd: to,
-        });
-      }
-    });
-  })
-  .use(listener);
-```
-
-The selection listener will be triggered when the selection is changed.
-So you don't need to compare them manually.
-
-For more details about listeners, please check [Using Listeners](/docs/api/plugin-listener).
-
-## Readonly Mode
-
----
-
-You can set the editor to readonly mode by setting the `editable` property.
-
-```typescript
-import { editorViewOptionsCtx } from "@milkdown/kit/core";
-
-let readonly = false;
-
-const editable = () => !readonly;
-
-Editor.make().config((ctx) => {
-  ctx.update(editorViewOptionsCtx, (prev) => ({
-    ...prev,
-    editable,
-  }));
-});
-
-// set to readonly after 5 secs.
-setTimeout(() => {
-  readonly = true;
-}, 5000);
-```
-
-### Use Cases for Readonly Mode
-
-- Preview mode
-- Document review
-- Print-friendly views
-- Mobile device optimization
-
-## Using Actions
-
----
-
-You can use an action to get the context value in a running editor on demand.
-
-For example, to get the markdown string by running an action:
-
-```typescript
-import { Editor, editorViewCtx, serializerCtx } from "@milkdown/kit/core";
-
-async function playWithEditor() {
-  const editor = await Editor.make().use(commonmark).create();
-
-  const getMarkdown = () =>
-    editor.action((ctx) => {
-      const editorView = ctx.get(editorViewCtx);
-      const serializer = ctx.get(serializerCtx);
-      return serializer(editorView.state.doc);
-    });
-
-  // get markdown string:
-  getMarkdown();
-}
-```
-
-We provide some macros out of the box, you can use them as actions:
-
-```typescript
-import { insert } from "@milkdown/kit/utils";
-
-editor.action(insert("# Hello milkdown"));
-```
-
-### Common Actions
-
-- Insert content
-- Get current selection
-- Apply formatting
-- Execute commands
-
-For more details about macros, please check [macros](/docs/guide/macros).
-
-## Destroying
-
----
-
-You can call `editor.destroy` to destroy an existing editor. You can create a new editor again with `editor.create`.
-
-```typescript
-await editor.destroy();
-
-// Then create again
-await editor.create();
-```
-
-If you just want to recreate the editor, you can use `editor.create`, it will **destroy the old editor and create a new one**.
-
-```typescript
-await editor.create();
-
-// This equals to call `editor.destroy` and `editor.create` again.
-await editor.create();
-```
-
-If you want to **clear the plugins and configs for the editor** when calling `editor.destroy`, you can pass `true` to `editor.destroy`.
-
-```typescript
-await editor.destroy(true);
-```

-# Keyboard Shortcuts
-
-Keyboard shortcuts are a crucial part of the editor's user experience. Milkdown provides a flexible system for configuring keyboard shortcuts through presets and plugins.
-
-## Default Shortcuts
-
----
-
-Milkdown comes with a set of default keyboard shortcuts from both presets and plugins. Here's a comprehensive list of all internal shortcuts:
-
-> #### 💡 Note
->
-> `Mod` represents the platform-specific modifier key:
->
-> - Windows/Linux: `Ctrl`
-> - macOS: `Command`
-
-### Commonmark Preset Shortcuts
-
-#### Headings
-
-| Shortcut             | Description             |

-| `Mod-Enter`/`Enter` | Exit table and break if possible |
-
-## Configuring Shortcuts
-
----
-
-You can customize keyboard shortcuts by configuring the keymap in the editor setup:
-
-```typescript
-import { blockquoteKeymap, commonmark } from "@milkdown/kit/preset/commonmark";
-
-Editor.make()
-  .config((ctx) => {
-    ctx.set(blockquoteKeymap.key, {
-      WrapInBlockquote: "Mod-Shift-b",
-      // or you may want to bind multiple keys:
-      WrapInBlockquote: ["Mod-Shift-b", "Mod-b"],
-    });
-  })
-  .use(commonmark);
-```
-
-## Defining Keymaps
-
----
-
-Keymaps in Milkdown are defined using the `$useKeymap` utility. Here's how to define keymaps for different features:
-
-### Heading Keymap Example
-
-```typescript
-import { $useKeymap } from "@milkdown/utils";
-import { commandsCtx } from "@milkdown/core";
-
-export const headingKeymap = $useKeymap("headingKeymap", {
-  TurnIntoH1: {
-    shortcuts: "Mod-Alt-1",
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => commands.call(wrapInHeadingCommand.key, 1);
-    },
-  },
-  TurnIntoH2: {
-    shortcuts: "Mod-Alt-2",
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => commands.call(wrapInHeadingCommand.key, 2);
-    },
-  },
-  // ... more heading levels
-  DowngradeHeading: {
-    shortcuts: ["Delete", "Backspace"],
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => commands.call(downgradeHeadingCommand.key);
-    },
-  },
-});
-```
-
-### Strong (Bold) Keymap Example
-
-```typescript
-import { $useKeymap } from "@milkdown/utils";
-import { commandsCtx } from "@milkdown/core";
-
-export const strongKeymap = $useKeymap("strongKeymap", {
-  ToggleBold: {
-    shortcuts: ["Mod-b"],
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => commands.call(toggleStrongCommand.key);
-    },
-  },
-});
-```
-
-### Keymap Structure
-
-Each keymap definition follows this structure:
-
-```typescript
-$useKeymap('keymapName', {
-  CommandName: {
-    shortcuts: string | string[],  // Single shortcut or array of shortcuts
-    priority?: number,             // (Optional) Priority of the shortcut
-    command: (ctx) => () => {      // Command to execute
-      const commands = ctx.get(commandsCtx);
-      return () => commands.call(commandKey, ...args);
-    },
-  },
-});
-```
-
-## Creating Custom Shortcuts
-
----
-
-If you need to add custom shortcuts, you can create a keymap plugin:
-
-```typescript
-import { $useKeymap } from "@milkdown/utils";
-import { commandsCtx } from "@milkdown/core";
-
-const customKeymap = $useKeymap("customKeymap", {
-  CustomCommand: {
-    shortcuts: "F1",
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => commands.call(someCommand.key);
-    },
-  },
-});
-
-// Usage
-Editor.make().use(customKeymap).use(commonmark);
-```
-
-### Example: Custom Command with Shortcut
-
-```typescript
-import { $command, $useKeymap } from "@milkdown/utils";
-import { commandsCtx } from "@milkdown/core";
-
-// Create a custom command
-const customCommand = $command("CustomCommand", (ctx) => () => {
-  return (state, dispatch) => {
-    // Command implementation
-    return true;
-  };
-});
-
-// Create a keymap
-const customKeymap = $useKeymap("customKeymap", {
-  CustomCommand: {
-    shortcuts: ["F1", "Mod-F1"], // Multiple shortcuts
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => commands.call(customCommand.key);
-    },
-  },
-});
-
-// Usage
-Editor.make().use(customCommand).use(customKeymap);
-```
-
-## Shortcut Priority
-
-You can control the order in which shortcuts are handled by specifying a `priority` property. Shortcuts with higher priority values are handled before those with lower values. This is useful if you want your custom shortcut to override or take precedence over other shortcuts that use the same key combination.
-
-When multiple shortcuts are registered for the same key, they are executed in order of priority. If a shortcut command returns `false`, the next shortcut with the same key will be tried. If it returns `true`, no further commands for that key will be run. This allows you to chain or override shortcut behaviors as needed.
-
-- The default priority is **50**.
-- Normal priority values should be between **1** and **100**.
-- Use higher numbers to ensure your shortcut is registered before others with the same key.
-
-#### Example: Using Priority
-
-```typescript
-import { $useKeymap } from "@milkdown/utils";
-import { commandsCtx } from "@milkdown/core";
-
-export const customKeymap = $useKeymap("customKeymap", {
-  CustomBold: {
-    shortcuts: "Mod-b",
-    priority: 100, // Highest in the normal range, so this runs first
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => {
-        // Custom bold logic
-        return true;
-      };
-    },
-  },
-  CustomAnotherBold: {
-    shortcuts: "Mod-b",
-    priority: 75, // Lower priority, will run only if CustomBold returns false
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => {
-        // Custom italic logic
-        return true;
-      };
-    },
-  },
-});
-```

-# Macros
-
-Macros are helper functions that provide a convenient way to interact with the editor. They take a payload (or nothing) as parameters and return a callback function that takes the `ctx` of milkdown as a parameter. When called with `ctx`, they apply the specified action to the editor.
-
-## Usage
-
-There are two main ways to use macros:
-
-```typescript
-import { insert } from "@milkdown/kit/utils";
-import { listenerCtx } from "@milkdown/plugin-listener";
-
-// Method 1: Using editor.action()
-editor.action(insert("# Hello Macro"));
-
-// Method 2: Using listener
-editor.config((ctx) => {
-  ctx.get(listenerCtx).mounted(insert("# Default Title"));
-});
-```
-
-## Available Macros
-
-### Content Manipulation
-
-#### `insert`
-
-Inserts content at the current cursor position. The macro accepts two parameters:
-
-- `markdown`: The markdown string to insert
-- `inline`: Optional boolean flag (default: false) that determines how the content is inserted
-
-```typescript
-import { insert } from "@milkdown/kit/utils";
-
-// Insert as block content (default)
-editor.action(insert("# Hello World"));
-
-// Insert as inline content
-editor.action(insert("inline text", true));
-```
-
-The behavior differs based on the `inline` parameter:
-
-- When `inline` is `false` (default):
-  - Replaces the current selection with the parsed markdown content
-  - Maintains the selection's open start/end positions
-  - Scrolls the view to show the inserted content
-- When `inline` is `true`:
-  - Attempts to insert the content as inline text
-  - If the content is text-only, replaces the selection with a text node
-  - Otherwise, replaces the selection with the parsed content
-
-#### `insertPos`
-
-Inserts markdown at a given position. The macro accepts two parameters:
-
-- `markdown`: The markdown string to insert
-- `pos`: The position to insert the content at
-
-```typescript
-import { insertPos } from "@milkdown/kit/utils";
-
-// Insert "Hello" at the beginning of the document
-editor.action(insertPos("Hello", 0));
-```
-
-#### `replaceAll`
-
-Replaces all content in the editor. The macro accepts two parameters:
-
-- `markdown`: The markdown string to replace the current content with
-- `flush`: Optional boolean flag (default: false) that determines how the replacement is performed
-
-```typescript
-import { replaceAll } from "@milkdown/kit/utils";
-
-// Replace content without flushing state
-editor.action(replaceAll("# New Content"));
-
-// Replace content and flush editor state
-editor.action(replaceAll("# New Content", true));
-```
-
-The behavior differs based on the `flush` parameter:
-
-- When `flush` is `false` (default):
-  - Replaces the entire document content with the new markdown
-  - Maintains the current editor state
-  - More efficient for simple content replacements
-- When `flush` is `true`:
-  - Creates a new editor state with the new content
-  - Reinitializes all plugins
-  - Useful when you need a completely fresh editor state
-
-#### `replaceRange`
-
-Replaces the content of the given range with a markdown string.
-
-```typescript
-import { replaceRange } from "@milkdown/kit/utils";
-
-// Replace content from position 0 to 5 with "Hello"
-editor.action(replaceRange("Hello", { from: 0, to: 5 }));
-```
-
-### Content Retrieval
-
-#### `getMarkdown`
-
-Gets the current content as markdown. If a range is provided, it will return the markdown for that range; otherwise, it will return the markdown for the entire document.
-
-```typescript
-import { getMarkdown } from "@milkdown/kit/utils";
-
-// Get markdown for the entire document
-const markdown = editor.action(getMarkdown());
-
-// Get markdown for a specific range
-const selectionMarkdown = editor.action(getMarkdown({ from: 0, to: 5 }));
-```
-
-#### `getHTML`
-
-Gets the current content as HTML.
-
-```typescript
-import { getHTML } from "@milkdown/kit/utils";
-
-const html = editor.action(getHTML());
-```
-
-### Editor State
-
-#### `forceUpdate`
-
-Forces the editor to update its state.
-
-```typescript
-import { forceUpdate } from "@milkdown/kit/utils";
-
-editor.action(forceUpdate());
-```
-
-#### `setAttr`
-
-Sets attributes for a node at a specific position. The macro accepts two parameters:
-
-- `pos`: The position of the node to update
-- `update`: A function that takes the previous attributes and returns the new attributes
-
-```typescript
-import { setAttr } from "@milkdown/kit/utils";
-
-// Update node attributes at position 10
-editor.action(
-  setAttr(10, (prevAttrs) => ({
-    ...prevAttrs,
-    class: "custom-class",
-  })),
-);
-
-// Example: Update heading level
-editor.action(
-  setAttr(10, (prevAttrs) => ({
-    ...prevAttrs,
-    level: 2,
-  })),
-);
-```
-
-The macro:
-
-- Takes a specific position in the document
-- Retrieves the node at that position
-- Applies the update function to modify the node's attributes
-- Dispatches the changes to update the editor state
-
-Note: The position must be valid and contain a node, otherwise the operation will be ignored.
-
-### Navigation
-
-#### `outline`
-
-Gets the outline of the document.
-
-```typescript
-import { outline } from "@milkdown/kit/utils";
-
-const docOutline = editor.action(outline());
-```
-
-### Command Execution
-
-#### `callCommand`
-
-Calls a registered command with optional payload. The macro has two overloads:
-
-Examples:
-
-```typescript
-import { callCommand } from "@milkdown/kit/utils";
-import { wrapInHeadingCommand } from "@milkdown/plugin-heading";
-
-// Using command key
-editor.action(callCommand(wrapInHeadingCommand.key, 1));
-
-// With complex payload
-editor.action(
-  callCommand("CustomCommand", {
-    type: "heading",
-    level: 1,
-    content: "New Heading",
-  }),
-);
-```
-
-The macro:
-
-- Takes a command key
-- Optionally accepts a payload parameter
-- Returns a boolean indicating whether the command was successful
-
-Note: The command must be registered in the editor's command context before it can be called.
-
-### Utility Macros
-
-#### `markdownToSlice`
-
-Converts a markdown string to a [slice](https://prosemirror.net/docs/ref/#model.Slice). This is useful when you need to manipulate the content before inserting it into the editor.
-
-```typescript
-import { markdownToSlice } from "@milkdown/kit/utils";
-
-const slice = editor.action(markdownToSlice("# Hello Slice"));
-```
-
-## Examples
-
-### Adding Content
-
-```typescript
-import { insert } from "@milkdown/kit/utils";
-import { listenerCtx } from "@milkdown/plugin-listener";
-
-editor.config((ctx) => {
-  ctx.get(listenerCtx).mounted(insert("# Welcome\nStart editing..."));
-});
-```
-
-### Saving Content
-
-```typescript
-import { getMarkdown } from "@milkdown/kit/utils";
-
-editor.config((ctx) => {
-  ctx.get(listenerCtx).updated(() => {
-    const content = getMarkdown()(ctx);
-    localStorage.setItem("editor-content", content);
-  });
-});
-```
-
-### Custom Command with Macro
-
-```typescript
-import { callCommand } from "@milkdown/kit/utils";
-
-editor.action(
-  callCommand("customCommand", {
-    type: "heading",
-    level: 1,
-    content: "New Heading",
-  }),
-);
-```

-# Prosemirror API
-
-Milkdown is built on top of prosemirror. Which means you can use the entire prosemirror API in Milkdown.
-To access the prosemirror API, you can use the `@milkdown/prose` package. It re-exports all of the prosemirror API.
-Using this package you can make sure that you are using the same version of prosemirror as Milkdown.
-
-## Installation
-
-To access a certain API in the `prosemirror-x` package, you need to import them from `@milkdown/kit/prose/x`.
-
-For example:
-
-```ts
-// Originally in prosemirror-state
-import { EditorState } from "@milkdown/kit/prose/state";
-// Originally in prosemirror-view
-import { EditorView } from "@milkdown/kit/prose/view";
-```
-
-## List of packages
-
-The following is a list of all the re-exported prosemirror API.
-
-- `@milkdown/kit/prose/changeset`
-- `@milkdown/kit/prose/commands`
-- `@milkdown/kit/prose/dropcursor`
-- `@milkdown/kit/prose/gapcursor`

-# Styling Guide
-
-Milkdown is a headless editor, which means it doesn't come with any default styles. This gives you complete control over the appearance of your editor. You can either use existing themes or create your own custom styling solution.
-
-# Styling Crepe Theme
-
----
-
-Crepe is a collection of themes for Milkdown that provides both light and dark variants. The theme structure is organized as follows:
-
-```
-theme/
-├── common/         # Shared styles and utilities
-├── crepe/          # Light theme variant
-├── crepe-dark/     # Dark theme variant
-├── frame/          # Frame theme (light)
-├── frame-dark/     # Frame theme (dark)
-├── nord/           # Nord theme (light)
-└── nord-dark/      # Nord theme (dark)
-```
-
-## Using Crepe Theme
-
-To use the Crepe theme in your project:
-
-```ts
-// Import base styles first
-import "@milkdown/crepe/theme/common/style.css";
-
-// Choose the theme you want to use
-import "@milkdown/crepe/theme/crepe.css";
-```
-
-## Theme Variables
-
-Crepe theme uses CSS variables for consistent styling. Here are all the available variables:
-
-### Colors
-
-```css
-.milkdown {
-  /* Background Colors */
-  --crepe-color-background: #fffdfb; /* Main background color */
-  --crepe-color-surface: #fff8f4; /* Surface color for cards/panels */
-  --crepe-color-surface-low: #fff1e5; /* Lower surface color for depth */

-
-## Customizing Crepe Theme

-You can customize the Crepe theme by overriding its variables:
-
-```css
-/* custom-overrides.css */
-.crepe .milkdown {
-  /* Override colors */
-  --crepe-color-primary: #your-primary-color;
-  --crepe-color-background: #your-background-color;
-
-  /* Override typography */
-  --crepe-font-default: "Your Font", sans-serif;
-
-  /* Override shadows */
-  --crepe-shadow-1: your-shadow-value;
-}
-```
-
-# Styling Milkdown
-
----
-
-## Basic Styling
-
-The editor is rendered within a container that has the class `.milkdown`, and the editable content area is wrapped in a container with the class `.editor`. You can use these classes to scope your styles:
-
-```css
-/* Basic styling example */
-.milkdown .editor {
-  max-width: 800px;
-  margin: 0 auto;
-  padding: 1rem;
-}
-
-.milkdown .editor p {
-  margin: 1rem 0;
-  line-height: 1.6;
-}
-```
-
-## Node and Mark Classes
-
-Milkdown provides default class names for each node and mark. Here are some common examples:
-
-```css
-/* Paragraph styling */
-.milkdown .editor .paragraph {
-  margin: 1rem 0;
-}
-
-/* Heading styling */
-.milkdown .editor .heading {
-  font-weight: 600;
-  margin: 1.5rem 0 1rem;
-}
-
-/* List styling */
-.milkdown .editor .bullet-list {
-  padding-left: 1.5rem;
-}
-
-.milkdown .editor .ordered-list {
-  padding-left: 1.5rem;
-}
-```
-
-## Custom Attributes
-
-You can add custom attributes to nodes and marks, which is particularly useful when working with CSS frameworks like Tailwind CSS.
-
-```typescript
-import { Editor, editorViewOptionsCtx } from "@milkdown/kit/core";
-import {
-  commonmark,
-  headingAttr,
-  paragraphAttr,
-} from "@milkdown/kit/preset/commonmark";
-
-Editor.make()
-  .config((ctx) => {
-    // Add attributes to the editor container
-    ctx.update(editorViewOptionsCtx, (prev) => ({
-      ...prev,
-      attributes: {
-        class: "milkdown-editor mx-auto outline-hidden",
-        spellcheck: "false",
-      },
-    }));
-
-    // Add attributes to nodes and marks
-    ctx.set(headingAttr.key, (node) => {
-      const level = node.attrs.level;
-      return {
-        class: `heading-${level} font-bold`,
-        "data-level": level,
-      };
-    });
-
-    ctx.set(paragraphAttr.key, () => ({
-      class: "text-base leading-relaxed",
-    }));
-  })
-  .use(commonmark);
-```
-
-# Best Practices
-
----
-
-1. **Use CSS Variables**: Define your theme's colors and spacing using CSS variables for easy customization.
-2. **Responsive Design**: Ensure your editor styles work well on different screen sizes.
-3. **Dark Mode Support**: Consider adding dark mode support using CSS variables and media queries.
-4. **Accessibility**: Maintain good contrast ratios and readable font sizes.
-5. **Performance**: Keep your CSS selectors specific and avoid overly complex rules.

-# Why Milkdown
-
-There are different kinds of markdown editors, such as [Typora](https://typora.io/), [tui](https://github.com/nhn/tui.editor) and [Bear](https://bear.app/).
-They work pretty well for writing notes in markdown on different platforms. So why bother making Milkdown?
-
-Milkdown aims to provide an **open source solution** for developers to make their editors more powerful, and attractive, it also ensures it runs everywhere.
-
----
-
-## Open Source & Easy to Integrate
-
-Different from industrial apps such as [Notion](https://notion.so) and [Typora](https://typora.io/),
-Milkdown is open source and fully free. You can integrate it everywhere legally.
-
-> If you like milkdown, please consider to fund me in order to help with the maintenance.
-
-## Plugin Driven
-
-Milkdown treats every feature as a plugin.
-With this pattern, developers can choose what they need in an editor instead of bundling all features even they won't need.
-Developers can extend their plugins to satisfy their habits such as defining a vim keymap via a custom plugin.
-
-## Reliable
-
-Milkdown is powered by [Prosemirror](https://prosemirror.net/) and [Remark](https://github.com/remarkjs/remark), which has a large community and stands the test of the industry.
-What's more, plugins from the prosemirror and remark community can be easily reused in order to build a Milkdown plugin.
-
-## Themable & Hackable
-
-Themes and plugins for Milkdown can be shared and installed using npm packages. Milkdown is a headless component, which means you can fully control its style.

-
-- [x] 🥛 Core: The core of Milkdown, which provides the plugin loading system with the editor concepts.
-- [x] 🧇 Plugins: A set of plugins that can be used to extend the functionalities of the editor.
-- [x] 🍮 Components: Some headless components that can be used to build your own editor.
-
-At the start, you may find it hard to understand all these concepts.
-But don't worry, we have this `@milkdown/crepe` editor for you to get started quickly.

-# Composable Plugins
-
-In the previous section, we showed you how to create a plugin from scratch. Luckily, you don't need to do that in most cases. Milkdown provides a lot of helpers in [@milkdown/utils](/docs/api/utils) to make it easier to create plugins. The **composable** here means that you can use the plugin in other plugins. For example, you can use a command plugin in a keymap plugin. This is a very common pattern in Milkdown.
-
-I'll show you some examples of how to use composable plugins. But I won't go into detail about the options and the usage of each plugin. You can find the details in the [API reference](/docs/api/utils#composable).
-
-## Schema
-
-The schema plugin is the most important plugin in Milkdown. It defines the structure of the document. A schema plugin in milkdown is a super set of the [node schema spec](https://prosemirror.net/docs/ref/#model.NodeSpec) or [mark schema spec](https://prosemirror.net/docs/ref/#model.MarkSpec) in ProseMirror.
-
-Let's create a simple blockquote node plugin as an example:
-
-```typescript
-import { $node } from "@milkdown/kit/utils";
-
-const blockquote = $node("blockquote", () => ({
-  content: "block+",
-  group: "block",
-  defining: true,
-  parseDOM: [{ tag: "blockquote" }],
-  toDOM: (node) => ["blockquote", ctx.get(blockquoteAttr.key)(node), 0],
-  parseMarkdown: {
-    match: ({ type }) => type === "blockquote",
-    runner: (state, node, type) => {
-      state.openNode(type).next(node.children).closeNode();
-    },
-  },
-  toMarkdown: {
-    match: (node) => node.type.name === "blockquote",
-    runner: (state, node) => {
-      state.openNode("blockquote").next(node.content).closeNode();
-    },
-  },
-}));
-```
-
-## Input Rule
-
-Since we have a blockquote node, we can create an input rule plugin to make it easier to create a blockquote node.
-We expect that when we type `> ` at the beginning of a line, the blockquote node will be created.
-
-```typescript
-import { wrappingInputRule } from "@milkdown/kit/prose/inputrules";
-import { $inputRule } from "@milkdown/kit/utils";
-
-export const wrapInBlockquoteInputRule = $inputRule(() =>
-  wrappingInputRule(/^\s*>\s$/, blockquoteSchema.type()),
-);
-```
-
-## Command
-
-We can also create a command plugin to create a blockquote node.
-The command is useful when we want to create a button to create a blockquote node.
-
-```typescript
-import { wrapIn } from "@milkdown/kit/prose/commands";

-
-export const wrapInBlockquoteCommand = $command(
-  "WrapInBlockquote",
-  () => () => wrapIn(blockquoteSchema.type()),
-);
-```
-
-## Shortcut
-
-We can also create a shortcut plugin for blockquote.
-Here we use `Ctrl + Shift + B` as the shortcut. When we press this shortcut, the blockquote node will be created.
-And we can also use the command we created in the previous section.
-
-```typescript
-import { commandsCtx } from "@milkdown/kit/core";
-import { $useKeymap } from "@milkdown/kit/utils";
-
-export const blockquoteKeymap = $useKeymap("blockquoteKeymap", {
-  WrapInBlockquote: {
-    shortcuts: "Mod-Shift-b",
-    command: (ctx) => {
-      const commands = ctx.get(commandsCtx);
-      return () => commands.call(wrapInBlockquoteCommand.key);
-    },
-  },
-});

-# Example: Block Plugin
-
-The **block plugin** adds a positional hook next to every top-level node (paragraphs, headings, lists, etc.).
-It is the foundation for features such as drag handles, quick-insert buttons or block toolbars.
-
-In Milkdown this functionality lives in `@milkdown/plugin-block` and – consistent with tooltip & slash – consists of:
-
-- a **BlockProvider** that deals with DOM positioning/lifecycle
-- a **blockFactory** – _implemented internally_ – exposed as two ctx slices: `blockSpec`, `blockPlugin`
-
-This guide covers:
-
-- Understanding the provider/service architecture.
-- Writing a **vanilla TypeScript** drag handle that lets you reorder blocks.
-- Mounting custom UIs in **React** and **Vue**.
-- Studying the production-ready _Block Handle_ feature inside Crepe.
-
----
-
-## 1. Anatomy of a Block Plugin
-
-Unlike tooltip/slash, `@milkdown/plugin-block` ships its factory slices directly:
-
-```ts
-import { blockSpec, blockPlugin } from "@milkdown/plugin-block";
-```
-
-You normally interact with **BlockProvider** which talks to an internal _BlockService_: the service listens to mouse / drag events, figures out which node is **active** and sends `show` / `hide` messages to the provider.
-Your job is to decide how to render a UI for that active node.
-
-Key APIs:
-
-- `new BlockProvider({ ctx, content, ... })` – similar to Tooltip/Slash.
-- `provider.active` – info about the currently focused block (`node`, `pos`, `el`).
-- Optional callbacks: `getOffset`, `getPlacement`, `getPosition` for fine-grained positioning.
-
----
-
-## 2. Minimal Vanilla Drag Handle
-
-Below we build a small **drag handle** that appears on hover and lets you drag-n-drop any block.
-
-```ts
-import { block, blockPlugin } from "@milkdown/plugin-block";
-import { BlockProvider } from "@milkdown/plugin-block/block-provider"; // path depending on bundler
-import { Editor } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-
-// 1️⃣ Create DOM element for the handle
-const handle = document.createElement("div");
-handle.className = "drag-handle";
-handle.innerHTML = "≡";
-handle.style.cssText = `
-  width:20px;height:20px;display:flex;align-items:center;justify-content:center;
-  cursor:grab;border-radius:4px;background:#f2f3f5;color:#555;user-select:none;
-`;
-
-// 2️⃣ Build provider – show only when mouse is over a block
-const provider = (ctx: Ctx) => {
-  const provider = new BlockProvider({
-    ctx,
-    content: handle,
-    getOffset: () => 8,
-  });
-
-  return {
-    update: provider.update,
-    destroy: provider.destroy,
-  };
-};
-
-// 3️⃣ Wire provider to Milkdown
-const blockConfig = (ctx: Ctx) => {
-  ctx.set(blockSpec.key, {
-    view: provider(ctx),
-  });
-};
-
-Editor.make().config(blockConfig).use(commonmark).use(block).create();
-```
-
-Drag & Drop:
-
-The HTML element has `cursor:grab`. The internal `BlockService` automatically sets `draggable` and wires ProseMirror's drag-events so you can reorder blocks without extra code 👉 nice!
-
----
-
-## 3. Framework Examples
-
-### React
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/react-block"}
-
-The React demo renders a `<BlockHandle/>` component, keeps drag state in hooks and feeds the root element to `BlockProvider`.
-
-### Vue
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/vue-block"}
-
-Vue's `<BlockHandle>` uses `Teleport` and reactive refs exactly like the tooltip/slash examples.
-
----
-
-## 4. Real-world Feature – Crepe Block Handle
-
-Crepe brings all the pieces together to create a **block edit** experience that combines a drag handle **and** a plus-button to open the slash menu:
-
-```text
-packages/crepe/src/feature/block-edit/handle/
-```
-
-Things worth exploring:
-
-1. **Dynamic placement** via `getPlacement` (centred vs top-aligned depending on node height).
-2. Filtering nodes with `blockConfig.filterNodes` so handles do not appear inside tables / math / blockquotes.
-3. Programmatically showing the _slash menu_ after pressing the "+" button.
-
----
-
-## 5. Summary & Next Steps
-
-`@milkdown/plugin-block` is the Swiss-army knife for any block-level UI: drag handles, add-buttons, side toolbars…
-Combine it with tooltip/slash to build sophisticated editors.
-
-Hack on the examples, tweak positioning callbacks, and ship your own block goodies 🚀.

-# Example: Iframe Plugin
-
-This guide demonstrates how to create a custom iframe syntax plugin for Milkdown. This plugin allows you to embed iframes directly in your markdown content using a simple directive syntax.
-
-## Overview
-
----
-
-The iframe plugin enables you to embed external web content using the following syntax:
-
-```markdown
-::iframe{src="https://example.com"}
-```
-
-This will render as an embedded iframe in your document.
-
-## Implementation Steps
-
----
-
-To create a custom syntax plugin in Milkdown, we need to implement five key components:
-
-1. **Remark Plugin**: Parse the custom syntax
-2. **Schema Definition**: Define the node structure
-3. **Parser**: Convert markdown to ProseMirror nodes
-4. **Serializer**: Convert ProseMirror nodes back to markdown
-5. **Input Rules**: Handle user input
-
-Let's implement each component:
-
-## 1. Remark Plugin
-
----
-
-First, we use the `remark-directive` plugin to support our custom syntax. This plugin allows us to define custom directives in markdown.
-
-```typescript
-import directive from "remark-directive";
-import { $remark } from "@milkdown/kit/utils";
-
-const remarkDirective = $remark("remarkDirective", () => directive);
-```
-
-## 2. Schema Definition
-
----
-
-Next, we define the schema for our iframe node. The schema specifies how the node behaves and appears in the editor.
-
-```typescript
-import { $node } from "@milkdown/kit/utils";
-import { Node } from "@milkdown/kit/prose/model";
-
-const iframeNode = $node("iframe", () => ({
-  group: "block", // Block-level node
-  atom: true, // Cannot be split
-  isolating: true, // Cannot be merged with adjacent nodes
-  marks: "", // No marks allowed
-  attrs: {
-    src: { default: null }, // URL attribute
-  },
-  parseDOM: [
-    {
-      tag: "iframe",
-      getAttrs: (dom) => ({
-        src: (dom as HTMLElement).getAttribute("src"),
-      }),
-    },
-  ],
-  toDOM: (node: Node) => [
-    "iframe",
-    { ...node.attrs, contenteditable: false }, // Prevent editing iframe content
-    0,
-  ],
-}));
-```
-
-## 3. Parser
-
----
-
-The parser converts our markdown syntax into ProseMirror nodes. It looks for the `leafDirective` type with the name "iframe".
-
-```typescript
-parseMarkdown: {
-  match: (node) => node.type === 'leafDirective' && node.name === 'iframe',
-  runner: (state, node, type) => {
-    state.addNode(type, { src: (node.attributes as { src: string }).src });
-  },
-},
-```
-
-## 4. Serializer
-
----
-
-The serializer converts ProseMirror nodes back to markdown format.
-
-```typescript
-toMarkdown: {
-  match: (node) => node.type.name === 'iframe',
-  runner: (state, node) => {
-    state.addNode('leafDirective', undefined, undefined, {
-      name: 'iframe',
-      attributes: { src: node.attrs.src },
-    });
-  },
-},
-```
-
-## 5. Input Rules
-
----
-
-Input rules handle user typing and convert the syntax into an iframe node.
-
-```typescript
-import { InputRule } from "@milkdown/kit/prose";
-import { $inputRule } from "@milkdown/kit/utils";
-
-const iframeInputRule = $inputRule(
-  () =>
-    new InputRule(
-      /::iframe\{src\="(?<src>[^"]+)?"?\}/,
-      (state, match, start, end) => {
-        const [okay, src = ""] = match;
-        const { tr } = state;
-        if (okay) {
-          tr.replaceWith(start - 1, end, iframeNode.type().create({ src }));
-        }
-        return tr;
-      },
-    ),
-);
-```
-
-## Usage
-
----
-
-To use the iframe plugin, add it to your Milkdown editor configuration:
-
-```typescript
-import { Editor } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-
-Editor.make()
-  .use([remarkDirective, iframeNode, iframeInputRule])
-  .use(commonmark)
-  .create();
-```
-

-# Example: Marker Plugin
-
-This guide demonstrates how to create a custom marker syntax plugin for Milkdown. This plugin allows you to mark text with custom colors using a simple markdown syntax.
-
-## Overview
-
----
-
-The marker plugin enables you to mark text using the following syntax:
-
-```markdown
-==marked text==
-=={#EE4B2B}marked text with color==
-```
-
-This will render as marked text in your document, with the option to specify custom colors.
-
-## Implementation Steps
-
----
-
-To create a custom marker syntax plugin in Milkdown, we need to implement several components:
-
-1. **Remark Plugin**: Parse the custom syntax
-2. **Schema Definition**: Define the mark structure
-3. **Parser**: Convert markdown to ProseMirror marks
-4. **Serializer**: Convert ProseMirror marks back to markdown
-5. **Input Rules**: Handle user input
-6. **Color Picker**: Add UI for color selection
-
-Let's implement each component:
-
-## 1. Remark Plugin
-
----
-
-First, we create a remark plugin to handle our custom marker syntax:
-
-> ⚠️ The real implementation is more complex, but we simplify it for the sake of the example.
-> Under the hood, you'll need to write a [micromark extension](https://github.com/micromark/micromark) to make it works correctly.
-
-```typescript
-import { $remark } from "@milkdown/kit/utils";
-
-const remarkMarkColor = () => {
-  return (tree: any) => {
-    visit(tree, "text", (node: any, index: number, parent: any) => {
-      const match = node.value.match(/==(?:{#([^}]+)})?([^=]+)==/);
-      if (match) {
-        const [_, color, text] = match;
-        const mark = {
-          type: "mark",
-          data: { color },
-          children: [{ type: "text", value: text }],
-        };
-        parent.children.splice(index, 1, mark);
-      }
-    });
-  };
-};
-
-const milkdownMarkColorPlugin = $remark("markColor", () => remarkMarkColor);
-```
-
-## 2. Schema Definition
-
----
-
-Next, we define the schema for our marker:
-
-```typescript
-import { $markSchema } from "@milkdown/kit/utils";
-import { Mark } from "mdast";
-
-export const DEFAULT_COLOR = "#ffff00";
-
-export const markSchema = $markSchema("mark", () => ({
-  attrs: {
-    color: {
-      default: DEFAULT_COLOR,
-      validate: "string",
-    },
-  },
-  parseDOM: [
-    {
-      tag: "mark",
-      getAttrs: (node: HTMLElement) => ({
-        color: node.style.backgroundColor,
-      }),
-    },
-  ],
-  toDOM: (mark) => ["mark", { style: `background-color: ${mark.attrs.color}` }],
-  parseMarkdown: {
-    match: (node) => node.type === "mark",
-    runner: (state, node, markType) => {
-      const color = (node as Mark).data?.color;
-      state.openMark(markType, { color });
-      state.next(node.children);
-      state.closeMark(markType);
-    },
-  },
-  toMarkdown: {
-    match: (node) => node.type.name === "mark",
-    runner: (state, mark) => {
-      let color = mark.attrs.color;
-      if (color?.toLowerCase() === DEFAULT_COLOR.toLowerCase()) {
-        color = undefined;
-      }
-      state.withMark(mark, "mark", undefined, {
-        data: { color },
-      });
-    },
-  },
-}));
-```
-
-## 3. Input Rules
-
----
-
-We add input rules to handle user typing:
-
-```typescript
-import { $inputRule } from "@milkdown/kit/utils";
-import { InputRule } from "@milkdown/kit/prose";
-
-const markInputRule = $inputRule(
-  () =>
-    new InputRule(/==(?:{#([^}]+)})?([^=]+)==/, (state, match, start, end) => {
-      const [okay, color, text] = match;
-      const { tr } = state;
-      if (okay) {
-        tr.addMark(
-          start,
-          end,
-          markSchema.type().create({ color: color || DEFAULT_COLOR }),
-        );
-      }
-      return tr;
-    }),
-);
-```
-
-## 4. Color Picker Tooltip
-
----
-
-To enhance the user experience, we add a color picker tooltip:
-
-```typescript
-export const colorPickerTooltip = tooltipFactory("color-picker");
-
-class TooltipPluginView {
-  // ... implementation
-}
-
-export const colorPickerTooltipConfig = (ctx: Ctx) => {
-  ctx.set(colorPickerTooltip.key, {
-    view: () => new TooltipPluginView(ctx),
-  });
-};
-```
-
-## Usage
-
----
-
-To use the marker plugin, add it to your Milkdown editor configuration:
-
-```typescript
-import { Editor } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-
-Editor.make()
-  .use(milkdownMarkColorPlugin)
-  .use(markSchema)
-  .use(markInputRule)
-  .use(colorPickerTooltip)
-  .use(commonmark)
-  .create();

-# Example: Slash Plugin
-
-After reading the tooltip guide you already know how Milkdown separates **positioning logic** (provider) from **editor wiring** (ctx slices produced by a factory).
-The `@milkdown/plugin-slash` package applies exactly the same idea but focuses on _command palettes_ triggered by a character – familiar to `/` menus in modern editors.
-
-This document shows you how to:
-
-- Understand what the slash plugin gives you out-of-the-box.
-- Build a **vanilla TypeScript** implementation of a basic `/` menu.
-- Use the slash provider with **React** and **Vue**.
-- Explore a full-blown menu feature that ships inside Milkdown's Crepe UI.
-
----
-
-## 1. Anatomy of a Slash Plugin
-
-`@milkdown/plugin-slash` exports two utilities:
-
-1. **`SlashProvider`** – Measures the caret position and manages show / hide of your menu.
-2. **`slashFactory(id)`** – Generates a ctx slice & ProseMirror plugin pair that plugs the provider into the editor.
-
-```ts
-import { slashFactory } from "@milkdown/plugin-slash";
-
-export const [mySlashSpec, mySlashPlugin] = slashFactory("my");
-```
-
-Just like the tooltip factory:
-
-- `mySlashSpec` is where you put a `PluginSpec` (what ProseMirror needs).
-- `mySlashPlugin` turns that spec into a runtime plugin.
-
----
-
-## 2. A Minimal Vanilla `/` Menu
-
-Below we create a small menu that suggests two commands whenever the user types `/`.
-
-```ts
-import { SlashProvider, slashFactory } from "@milkdown/plugin-slash";
-import { Editor } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-
-// DOM content of the menu – plain HTML for the demo
-const menu = document.createElement("div");
-menu.className = "slash-menu";
-menu.style.cssText = `
-  position:absolute;padding:4px 0;background:white;border:1px solid #eee;
-  box-shadow:0 2px 8px rgba(0,0,0,.15);border-radius:6px;font-size:14px;
-`;
-menu.innerHTML = `<ul style="margin:0;padding:0;list-style:none">
-  <li data-cmd="h1" style="padding:4px 12px;cursor:pointer">Heading 1</li>
-  <li data-cmd="bullet" style="padding:4px 12px;cursor:pointer">Bullet List</li>
-</ul>`;
-
-// Click handler – replace with real commands
-menu.addEventListener("click", (e) => {
-  const target = e.target as HTMLElement;
-  const cmd = target.dataset.cmd;
-  alert(`Run command: ${cmd}`);
-});
-
-// Provider positions & shows above DOM element
-const provider = new SlashProvider({
-  content: menu,
-  // show the menu when the last character before caret is '/'
-  shouldShow(view) {
-    return provider.getContent(view)?.endsWith("/") ?? false;
-  },
-  offset: 8,
-});
-
-const slash = slashFactory("demo");
-const slashConfig = (ctx: Ctx) => {
-  ctx.set(slash.key, {
-    view: () => ({
-      update: provider.update,
-      destroy: provider.destroy,
-    }),
-  });
-};
-
-Editor.make().config(slashConfig).use(commonmark).use(slash).create();
-```
-
-Key takeaways:
-
-- `SlashProvider` has a helper `getContent(view)` to fetch text before the caret – handy for filtering.
-- You decide **when to show** the menu via the `shouldShow` callback (default: when last char is `/`).
-- The provider only manipulates **position + visibility**; rendering & commands are completely yours.

-
-## 3. Framework Examples
-
-### React
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/react-slash"}
-
-Highlights:
-
-1. A `<SlashMenu/>` React component renders the list.
-2. The component root is passed to `SlashProvider` (just like the tooltip demo).
-3. React hooks manage internal focus & keyboard navigation.
-
-### Vue
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/vue-slash"}
-
-The Vue version uses `Teleport` to append the menu to `document.body` and `ref` / `watch` for reactivity.
-
----
-
-## 4. Real-world Feature – Crepe Block Menu
-
-Milkdown's **Crepe** UI implements an extensible block-level menu on top of the slash plugin. You'll find the source code at:
-
-```text
-packages/crepe/src/feature/block-edit/menu/
-```
-
-Notable patterns to look for:
-
-- **Context slices** (`menu` / `menuAPI`) to expose imperative `show` & `hide` methods.
-- Filtering commands based on the current text after `/`.
-- Preventing the menu inside `code` blocks or lists.
-
-Studying this folder is a great next step once you master the basics.
-
----
-
-## 5. Summary & Next Steps
-
-- `@milkdown/plugin-slash` gives you caret detection + positioning – nothing else.
-- UI, behaviour, and commands are fully customisable.
-
-Fork one of the examples above, add your own commands, and you'll have a modern `/` command palette in minutes ✨.

-# Example: Tooltip Plugin
-
-This guide walks you through creating and using **tooltip-based plugins** in Milkdown.
-You will learn how the low-level `@milkdown/plugin-tooltip` works and how to build richer experiences on top of it in **vanilla TypeScript**, **React**, and **Vue**.
-
-> **TL;DR** – A tooltip in Milkdown is nothing more than a ProseMirror plugin created by `tooltipFactory(id)`.
-> It receives position information from the editor and renders any DOM of your choice.
-> Everything else (buttons, inputs, styling, framework bindings) can be composed on top of that.
-
-## 1. Anatomy of a Tooltip
-
----
-
-At its core the tooltip plugin exported from `@milkdown/plugin-tooltip` contains two helpers:
-
-1. **`TooltipProvider`** – An utility class powered by [floating-ui](https://floating-ui.com/) to calculate the tooltip position.
-2. **`tooltipFactory(id)`** – A factory that returns a pair of Milkdown plugin slices which wire the provider into the editor.
-
-The factory is extremely small (≈40 lines):
-
-```ts
-import { tooltipFactory } from "@milkdown/plugin-tooltip";
-
-// Create a tooltip identified by the string "my".
-export const [myTooltipSpec, myTooltipPlugin] = tooltipFactory("my");
-```
-
-The first element (`myTooltipSpec`) is a **ctx slice** that stores a `PluginSpec`, while the second one (`myTooltipPlugin`) is the real ProseMirror plugin which consumes that spec.
-
-## 2. A Minimal Vanilla Tooltip
-
----
-
-Below is the complete code for a tooltip that shows the **length of the current selection**.
-
-```ts
-import { Editor } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-import { TooltipProvider, tooltipFactory } from "@milkdown/plugin-tooltip";
-
-// 1) Prepare DOM that we will mount into the page.
-const el = document.createElement("div");
-el.className = "selection-length";
-el.style.cssText = `
-  pointer-events:none;
-  background:#333;color:#fff;padding:2px 6px;border-radius:4px;font-size:12px;
-`;
-
-// 2) Build a provider which updates the content.
-const provider = new TooltipProvider({
-  content: el,
-  shouldShow: (view) => !!view.state.selection.content().size,
-});
-
-// 3) Bridge provider & editor.
-const tooltip = tooltipFactory("sel-length");
-const tooltipConfig = (ctx: Ctx) => {
-  ctx.set(selectionTooltipSpec.key, {
-    view: () => ({
-      update: provider.update,
-      destroy: provider.destroy,
-    }),
-  });
-};
-
-Editor.make().config(tooltipConfig).use(commonmark).use(tooltip).create();
-```
-
-Key points:
-
-- We **create** any DOM element we like (`el`).
-- `TooltipProvider` tracks the editor position and moves the element.
-- `tooltipFactory` wraps the provider into a pluggable slice.
-
-## 3. Framework Examples
-
----
-
-Sometimes building UI is easier in your favourite framework.
-Because the tooltip provider only deals with **DOM elements**, you can freely render React, Vue or Svelte components and pass their root node to the provider.
-
-### React
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/react-tooltip"}
-
-The React example shows how to:
-
-1. Create a React component (`<SelectionTooltip/>`).
-2. Render it into a portal and give the root HTML element to `TooltipProvider`.
-3. Re-use React state/hooks while Milkdown takes care of positioning.
-
-### Vue
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/vue-tooltip"}
-
-The Vue example follows the same pattern with `defineComponent` and `teleport`.
-
-## 4. Real-world Examples
-
----
-
-### 4-1. Link Tooltip (_@milkdown/component/link-tooltip_)
-
-The [link tooltip](https://github.com/Milkdown/milkdown/tree/main/packages/components/src/link-tooltip) demonstrates how to:
-
-- Maintain UI **state** (`preview` vs `edit`) in ctx slices.
-- Communicate with the editor through an **API slice** (add / edit / remove links).
-- Render framework-agnostic UI inside a tooltip provider.
-
-Have a look at the files below to see those techniques in action:
-
-```text

-### 4-2. Toolbar Feature (_@milkdown/crepe/feature/toolbar_)
-
-The toolbar in the [crepe](https://github.com/Milkdown/milkdown/tree/main/packages/crepe) package pushes the idea further by:
-
-- Using multiple tooltip instances (one per button group).
-- Rendering the UI with Vue _inside_ the provider.
-- Sharing configuration via ctx slices so that every button is extensible by third-party plugins.
-
-You can browse the implementation starting from
-

-
-## 5. Summary & Next Steps
-
----
-
-- `@milkdown/plugin-tooltip` offers **just enough** abstraction: positioning & lifecycle.
-- Everything else – **state, styling, framework integration** – is totally up to you.
-
-Try to customise one of the examples above, then ship your own tooltip-powered features 🤟.

-# Plugins 101
-
-In this section we will show you the basic information of the plugin.
-In most cases, you will not need to write plugins without helpers.
-But it can help you understand the plugin system and what happens under the hood.
-
-## Structure Overview
-
-Generally speaking, a plugin will have following structure:
-
-```typescript
-import { MilkdownPlugin } from "@milkdown/kit/ctx";
-
-const myPlugin: MilkdownPlugin = (ctx) => {
-  // #1 prepare plugin
-  return async () => {
-    // #2 run plugin
-    return async () => {
-      // #3 clean up plugin
-    };
-  };
-};
-```
-
-Each plugin is composed by three parts:
-
-1. _Prepare_: this part will be executed when plugin is registered in milkdown by `.use` method.
-2. _Run_: this part will be executed when plugin is actually loaded.
-3. _Post_: this part will be executed when plugin is removed by `.remove` method or editor is destroyed.
-
-## Timer
-
-Timer can be used to decide when to load the current plugin and how current plugin can influence other plugin's loading status.
-
-You can use `ctx.wait` to wait a timer to finish.
-
-```typescript
-import { MilkdownPlugin, Complete } from "@milkdown/kit/core";
-
-const myPlugin: MilkdownPlugin = (ctx) => {
-  return async () => {
-    const start = Date.now();
-
-    await ctx.wait(Complete);
-
-    const end = Date.now();
-
-    console.log("Milkdown load duration: ", end - start);
-  };
-};
-```
-
-You can also create your own timer and influence other plugins load time.
-For example, let's create a plugin that will fetch markdown content from remote server as editor's default value.
-
-```typescript
-import {
-  MilkdownPlugin,
-  editorStateTimerCtx,
-  defaultValueCtx,
-  createTimer,
-} from "@milkdown/kit/core";
-
-const RemoteTimer = createTimer("RemoteTimer");
-
-const remotePlugin: MilkdownPlugin = (ctx) => {
-  // register timer
-  ctx.record(RemoteTimer);
-
-  return async () => {
-    // the editorState plugin will wait for this timer to finish before initialize editor state.
-    ctx.update(editorStateTimerCtx, (timers) => timers.concat(RemoteTimer));
-
-    const defaultMarkdown = await fetchMarkdownAPI();
-    ctx.set(defaultValueCtx, defaultMarkdown);
-
-    // mark timer as complete
-    ctx.done(RemoteTimer);
-
-    return async () => {
-      await SomeAPI();
-
-      // remove timer when plugin is removed
-      ctx.clearTimer(RemoteTimer);
-    };
-  };
-};
-```
-
-It has following steps:
-
-1. We use `createTimer` to create a timer, and use `pre.record` to register it into milkdown.
-2. We update `editorStateTimerCtx` to tell the internal `editorState` plugin that before initialize editor state, it should wait our remote fetch process finished.
-3. After we get value from `fetchMarkdownAPI`, we set it as `defaultValue` and use `ctx.done` to mark a timer as complete.
-
-## Ctx
-
-We have used `ctx` several times in the above example, now we can try to understand what it is.
-
-Ctx is a data container which is shared in the entire editor instance. It's composed by a lot of slices. Every `slice` has a unique key and a value. You can change the value of a slice by `ctx.set` and `ctx.update`. And you can get the value of a slice by `ctx.get` with the slice key or name. Last but not least, you can remove a slice by `post.remove`.
-
-```typescript
-import { MilkdownPlugin, createSlice } from "@milkdown/kit/ctx";
-
-const counterCtx = createSlice(0, "counter");
-
-const counterPlugin: MilkdownPlugin = (ctx) => {
-  ctx.inject(counterCtx);
-
-  return () => {
-    // count is 0
-    const count0 = ctx.get(counterCtx);
-
-    // set count to 1
-    ctx.set(counterCtx, 1);
-
-    // now count is 1
-    const count1 = ctx.get(counterCtx);
-
-    // set count to n + 2
-    ctx.update(counterCtx, (prev) => prev + 2);
-
-    // now count is 3
-    const count2 = ctx.get(counterCtx);
-    // we can also get value by the slice name
-    const count3 = ctx.get("counter");
-
-    return () => {
-      // remove the slice
-      ctx.remove(counterCtx);
-    };
-  };
-};
-```
-
-We can use `createSlice` to create a ctx, and use `pre.inject` to inject the ctx into the editor.
-
-And when plugin processing, `ctx.get` can get the value of a ctx, `ctx.set` can set the value of a ctx, and `ctx.update` can update a ctx using callback function.
-
-So, we can use `ctx` combine with `timer` to decide when should a plugin be processed.
-
-```typescript
-import {
-  MilkdownPlugin,
-  SchemaReady,
-  Timer,
-  createSlice,
-} from "@milkdown/kit/core";
-
-const examplePluginTimersCtx = createSlice<Timer[]>([], "example-timer");
-
-const examplePlugin: MilkdownPlugin = (ctx) => {
-  ctx.inject(examplePluginTimersCtx, [SchemaReady]);
-  return async () => {
-    await Promise.all(
-      ctx.get(examplePluginTimersCtx).map((timer) => ctx.wait(timer)),
-    );
-    // or we can use a simplified syntax sugar
-    await ctx.waitTimers(examplePluginTimersCtx);
-
-    // do something
-  };
-};
-```
-
-With this pattern, if other plugins want to delay the process of `examplePlugin`, all they need to do is just add a timer into `examplePluginTimersCtx` with `ctx.update`.
-
-## Summary
-
-Now let's go back to the plugin structure. Since we have the knowledge of `timer` and `ctx`, we can understand what we should do in each part of a plugin.
-
-1. In `prepare` stage of the plugin, we can use `ctx.record` to register a timer, and use `ctx.inject` to inject a slice.
-2. In `run` stage of the plugin, we can use `ctx.wait` to wait a timer to finish, and use `ctx.get` to get the value of a slice. We can also change values of slices by `ctx.set` and `ctx.update`. And we can use `ctx.done` to mark a timer as complete.
-3. In `post` stage of the plugin, we can use `ctx.clearTimer` to clear a timer, and use `ctx.remove` to remove a slice.

-# Using Components
-
-Components are features work out of the box that built on top of plugins.
-Each component is a separate module. You can use them by importing them from `@milkdown/kit/component/*`.
-All components can be used just like plugins.
-
-```ts
-import { imageBlock } from "@milkdown/kit/component/image-block";
-import { Editor } from "@milkdown/kit/core";
-
-Editor.make().use(/* some other plugins */).use(imageBlock).create();
-```
-
-Components are designed to be headless, which means they are not opinionated about the UI.
-You can use them to build your own editor UI. Components are built by web components and can be used in any framework.

-# React Integration
-
-Milkdown provides first-class React support with dedicated packages and hooks for seamless integration. You can choose between Crepe, our feature-rich WYSIWYG editor, or the core Milkdown editor for more customization options.
-
-## Using Crepe
-
----
-
-Crepe is a powerful, feature-rich Markdown editor built on top of Milkdown that provides a more user-friendly editing experience.
-
-### Installation
-
-```bash
-npm install @milkdown/crepe @milkdown/react @milkdown/kit
-```
-
-### Implementation
-
-```tsx
-import { Crepe } from "@milkdown/crepe";
-import { Milkdown, MilkdownProvider, useEditor } from "@milkdown/react";
-
-const CrepeEditor: React.FC = () => {
-  const { get } = useEditor((root) => {
-    return new Crepe({ root });

-    </MilkdownProvider>
-  );
-};
-```

-
-## Using Milkdown
-
----
-
-For more advanced use cases or when you need full control over the editor's configuration, you can use the core Milkdown editor directly.
-
-### Install Dependencies
-
-```bash
-npm install @milkdown/react @milkdown/kit
-```
-
-### Basic Usage
-
-Here's a minimal example to get started:
-
-```tsx
-import { Editor, rootCtx } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-import { Milkdown, MilkdownProvider, useEditor } from "@milkdown/react";
-import { nord } from "@milkdown/theme-nord";
-
-const MilkdownEditor: React.FC = () => {
-  const { get } = useEditor((root) =>
-    Editor.make()
-      .config(nord)
-      .config((ctx) => {
-        ctx.set(rootCtx, root);
-      })
-      .use(commonmark),
-  );
-
-  return <Milkdown />;
-};
-
-export const MilkdownEditorWrapper: React.FC = () => {
-  return (
-    <MilkdownProvider>
-      <MilkdownEditor />
-    </MilkdownProvider>
-  );
-};
-```
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/react-commonmark"}
-
-## Advanced Usage
-
----
-
-### Accessing Editor Instance
-
-The `useInstance()` hook can only be used within components that are children of `MilkdownProvider`. It returns a tuple containing a loading state and a getter function to access the editor instance.
-
-```tsx
-import { useInstance } from "@milkdown/react";
-import { getMarkdown } from "@milkdown/utils";
-
-// ❌ This won't work - ParentComponent is outside MilkdownProvider
-const ParentComponent: React.FC = () => {
-  const [isLoading, getInstance] = useInstance(); // This will be [true, () => undefined]
-  return <MilkdownEditorWrapper />;
-};
-
-// ✅ This is the correct way - EditorControls is inside MilkdownProvider
-const EditorControls: React.FC = () => {
-  const [isLoading, getInstance] = useInstance();
-
-  const handleSave = () => {
-    if (isLoading) return;
-
-    const editor = getInstance();
-    if (!editor) return;
-
-    const content = editor.action(getMarkdown());
-    // Do something with the content
-  };
-
-  return (
-    <button onClick={handleSave} disabled={isLoading}>
-      Save
-    </button>
-  );
-};
-
-// ✅ Proper component structure
-const EditorWithControls: React.FC = () => {
-  return (
-    <MilkdownProvider>
-      <MilkdownEditorWrapper />
-      <EditorControls />
-    </MilkdownProvider>
-  );
-};
-```
-
-### Best Practices
-
-1. **Component Structure**
-   - Keep the editor component separate from business logic
-   - Wrap the editor with `MilkdownProvider` at the highest necessary level
-   - Use TypeScript for better type safety
-
-2. **Performance**
-   - Memoize the editor configuration if it's complex
-   - Use React.memo for the editor component if needed
-   - Avoid unnecessary re-renders of the editor
-
-### Common Use Cases
-
-**Form Integration**
-
-```tsx
-const FormWithEditor: React.FC = () => {
-  const [isLoading, getInstance] = useInstance();
-
-  const handleSubmit = (e: React.FormEvent) => {
-    e.preventDefault();
-    if (isLoading) return;
-
-    const editor = getInstance();
-    if (!editor) return;
-
-    const content = editor.action(getMarkdown());
-    // Submit form with content
-  };
-
-  return (
-    <form onSubmit={handleSubmit}>
-      <MilkdownEditorWrapper />
-      <button type="submit" disabled={isLoading}>
-        Submit
-      </button>
-    </form>
-  );
-};
-```
-
-**Auto-save**
-
-```tsx

-# Vue Integration
-
-Milkdown provides first-class Vue support with dedicated packages and hooks for seamless integration. You can choose between Crepe, our feature-rich WYSIWYG editor, or the core Milkdown editor for more customization options.
-
-> Vue version should be 3.x
-
-## Using Crepe
-
----
-
-Crepe is a powerful, feature-rich Markdown editor built on top of Milkdown that provides a more user-friendly editing experience.
-
-### Installation
-
-```bash
-npm install @milkdown/crepe @milkdown/vue @milkdown/kit
-```
-
-### Implementation
-
-```vue
-<!-- MilkdownEditor.vue -->
-<template>
-  <Milkdown />
-</template>
-
-<script>
-import { Crepe } from "@milkdown/crepe";
-import { Milkdown, MilkdownProvider, useEditor } from "@milkdown/vue";
-import { defineComponent } from "vue";
-
-export default defineComponent({
-  name: "MilkdownEditor",
-  components: {
-    Milkdown,
-  },
-  setup: () => {
-    const { get } = useEditor((root) => {
-      return new Crepe({ root });
-    });
-  },
-});
-</script>
-
-<!-- MilkdownEditorWrapper.vue -->
-<template>
-  <MilkdownProvider>
-    <MilkdownEditor />
-  </MilkdownProvider>
-</template>
-
-<script>
-import { MilkdownProvider } from "@milkdown/vue";
-import { defineComponent } from "vue";
-
-export default defineComponent({
-  name: "MilkdownEditorWrapper",
-  components: {
-    MilkdownProvider,
-  },
-});
-</script>
-```
-
-### Online Demo
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/vue-crepe"}
-
-## Using Milkdown
-
----
-
-For more advanced use cases or when you need full control over the editor's configuration, you can use the core Milkdown editor directly.
-
-### Install Dependencies
-
-```bash
-npm install @milkdown/vue @milkdown/kit @milkdown/theme-nord
-```
-
-### Basic Usage
-
-Here's a minimal example to get started:
-
-```vue
-<!-- MilkdownEditor.vue -->
-<template>
-  <Milkdown />
-</template>
-
-<script>
-import { Editor, rootCtx } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-import { nord } from "@milkdown/theme-nord";
-import { Milkdown, useEditor } from "@milkdown/vue";
-import { defineComponent } from "vue";
-
-export default defineComponent({
-  name: "MilkdownEditor",
-  components: {
-    Milkdown,
-  },
-  setup: () => {
-    const { get } = useEditor((root) =>
-      Editor.make()
-        .config(nord)
-        .config((ctx) => {
-          ctx.set(rootCtx, root);
-        })
-        .use(commonmark),
-    );
-  },
-});
-</script>
-
-<!-- MilkdownEditorWrapper.vue -->
-<template>
-  <MilkdownProvider>
-    <MilkdownEditor />
-  </MilkdownProvider>
-</template>
-
-<script>
-import { MilkdownProvider } from "@milkdown/vue";
-import { defineComponent } from "vue";
-
-export default defineComponent({
-  name: "MilkdownEditorWrapper",
-  components: {
-    MilkdownProvider,
-  },
-});
-</script>
-```
-
-::iframe{src="https://stackblitz.com/github/Milkdown/examples/tree/main/vue-commonmark"}
-
-## Advanced Usage
-
----
-
-### Accessing Editor Instance
-
-The `useInstance()` hook can only be used within components that are children of `MilkdownProvider`. It returns a tuple containing a loading state and a getter function to access the editor instance.
-
-```vue
-<!-- EditorControls.vue -->
-<template>
-  <button @click="handleSave" :disabled="isLoading">Save</button>
-</template>
-
-<script>
-import { useInstance } from "@milkdown/vue";
-import { defineComponent } from "vue";
-
-export default defineComponent({
-  name: "EditorControls",
-  setup: () => {
-    const [isLoading, getInstance] = useInstance();
-
-    const handleSave = () => {
-      if (isLoading.value) return;
-
-      const editor = getInstance();
-      if (!editor) return;
-
-      const content = editor.getMarkdown();
-      // Do something with the content
-    };
-
-    return {
-      isLoading,
-      handleSave,
-    };
-  },
-});
-</script>
-
-<!-- EditorWithControls.vue -->
-<template>
-  <MilkdownProvider>
-    <MilkdownEditor />
-    <EditorControls />
-  </MilkdownProvider>
-</template>
-
-<script>
-import { MilkdownProvider } from "@milkdown/vue";
-import { defineComponent } from "vue";
-
-export default defineComponent({
-  name: "EditorWithControls",
-  components: {
-    MilkdownProvider,
-  },
-});
-</script>
-```
-
-### Best Practices
-
-1. **Component Structure**
-   - Keep the editor component separate from business logic
-   - Wrap the editor with `MilkdownProvider` at the highest necessary level
-   - Use TypeScript for better type safety
-
-2. **Performance**
-   - Memoize the editor configuration if it's complex
-   - Use Vue's `shallowRef` for editor instance if needed
-   - Avoid unnecessary re-renders of the editor
-
-### Common Use Cases
-
-**Form Integration**
-
-```vue
-<template>
-  <form @submit.prevent="handleSubmit">
-    <MilkdownEditorWrapper />
-    <button type="submit" :disabled="isLoading">Submit</button>
-  </form>
-</template>
-
-<script>
-import { useInstance } from "@milkdown/vue";
-import { defineComponent } from "vue";
-
-export default defineComponent({
-  name: "FormWithEditor",
-  setup: () => {
-    const [isLoading, getInstance] = useInstance();
-
-    const handleSubmit = () => {
-      if (isLoading.value) return;
-
-      const editor = getInstance();
-      if (!editor) return;
-
-      const content = editor.getMarkdown();
-      // Submit form with content
-    };
-
-    return {
-      isLoading,
-      handleSubmit,
-    };
-  },
-});
-</script>
-```
-
-**Auto-save**
-
-```vue
-<template>
-  <Milkdown />
-</template>
-
-<script>
-import { Editor, rootCtx } from "@milkdown/kit/core";
-import { commonmark } from "@milkdown/kit/preset/commonmark";
-import { listener, listenerCtx } from "@milkdown/kit/plugin/listener";
-import { Milkdown, useEditor } from "@milkdown/vue";
-import { defineComponent } from "vue";
-
-export default defineComponent({
-  name: "AutoSaveEditor",
-  components: {
-    Milkdown,
-  },
-  setup: () => {
-    const { get } = useEditor((root) =>
-      Editor.make()
-        .config((ctx) => {
-          ctx.set(rootCtx, root);
-          // Add markdown listener for auto-save
-          ctx.get(listenerCtx).markdownUpdated((ctx, markdown) => {
-            // Save content to your backend or storage
-            saveToBackend(markdown);
-          });
-        })
-        .use(commonmark)
-        .use(listener),
-    );
-  },
-});
-</script>
-```
