MetonaEditor/CHANGELOG.md

Changelog

All notable changes to MetonaEditor will be documented in this file.

[0.4.0] - 2026-08-11

Added

• Playwright 浏览器冒烟测试: e2e/ 目录（本地宿主页 + 真实 Chromium），22 项断言覆盖渲染 / 输入实时预览 / 工具栏命令 / 三模式切换 / 主题 / 搜索插件 / 状态栏 / 撤销 / 实例 API，并自动检测页面 console 错误。npm run test:e2e 一键运行，CI 新增 e2e job。
• sideEffects: false: 便于消费方打包器 tree-shaking。

Fixed

• 实例 locale 未作用于全部 UI 文案: 状态栏、工具栏 tooltip、右键菜单、大纲标题、插入链接/图片占位、模式切换播报此前混用全局 t；浏览器默认语言与实例 locale 不一致时显示错误语言。现 _i18nCtx 提前至 DOM 构建前创建，所有 UI 文案统一走实例 t()。

Changed

• MeEditor.destroy() 全面复位: 额外清理全局静态钩子（beforeCreate/afterCreate/beforeChange 等），并自动重建内部全局插件注入钩子，保证 destroy() 后 MeEditor.use() 依旧可用。

Added

• 回归测试 5 个（实例 locale 决定状态栏/按钮/右键菜单文案、destroy 钩子清理与重建、destroy 后全局插件仍可用），总数 821 → 826。

---

[0.3.1] - 2026-08-10

Performance

• 高亮规则缓存: highlight() 不再每次调用重建正则规则表，按语言缓存（registerLanguage 覆盖时自动失效）。
• 统计增量计算: getStats() / _updateWordCount() / _renderGutter() 基于共同前缀/后缀的差异区间增量计算（含单词边界扩展保证一致），击键时不再对全文做 O(n) 正则。
• 大纲线性构建: outline 树构建由递归 O(n²) 改为迭代栈 O(n)，长文档无延迟。

Changed

• 拖放图片大小限制: 拖入 >500KB 的图片时 toast 警告且不插入，与 imagePaste 插件行为一致。
• scrollToLine 真实行高: 使用 getComputedStyle().lineHeight 替代硬编码 22px。
• undo/redo 光标恢复: 撤销/重做后光标位置 clamp 恢复（不越界）。
• selectionChange / cursorMove 与浮动工具栏解耦: 事件现无条件触发（floatingToolbar: false 时仍可用）。
• unregisterShortcut 大小写归一: 注册 Ctrl+B 可用 ctrl+b 注销。
• toast 动画接入 ANIMATIONS: animation 参数真正应用 enter/leave 变换与时长缓动（slide/fade/scale/bounce/flip/rotate/zoom）。
• 实例主题订阅随销毁断开: getThemeContext() 新增 dispose()，destroy() 时自动断开外部跟随的 MutationObserver / 轮询订阅。

Added

• 回归测试 20 个（高亮缓存失效 / 增量统计一致性与边界 / outline 树结构配对与长文档 / undo 光标 / selectionChange 解耦 / 快捷键归一 / toast 动画 / 拖放限大小 / 主题 dispose），总数 801 → 821。

[0.3.0] - 2026-08-10

Fixed

• 脚注 XSS 属性注入: 脚注引用的 fnId（[^id] 中的 id）此前未转义直接拼入 href / id 属性，[^a" onclick="x] 可注入事件属性；现经属性级转义，行内引用与脚注区渲染均覆盖。
• 全局插件静默失效: MeEditor.use('searchReplace' | 'shortcutHelp' | 'imagePaste') 此前在 beforeCreate 钩子安装，但此时 DOM 尚未构建、editor.textarea 不存在，三个依赖 textarea 的插件静默跳过；现改为 afterCreate 注入，DOM 就绪后再安装。
• 引用链接跨文档串数据: 行内渲染缓存仅以文本为 key，不同文档中相同文本 + 不同 [ref]: url 定义会命中彼此缓存返回错误链接；现缓存 key 附加 refs 指纹（parseMarkdown 预计算，renderTokens 直接调用时兜底）。
• underline 预览不可见: Ctrl+U 生成的 <u> 此前被解析器转义为字面量 <u>；现解析器白名单透传裸 <u> / </u>（无属性，带属性的 <u onclick=...> 仍被转义，无注入面），代码块 / 行内代码内不受影响。
• getStatus().locale 与实例不一致: 此前返回全局 locale，实例 setLocale 后状态不跟随；现返回实例 locale，渲染 env 的 locale 字段同步改为实例级。
• replaceAll 替换串 $ 语义陷阱: replaceAll 的替换文本现按字面处理（$ 无特殊含义）；replaceAllRegex 保留正则捕获组语义（$1）不变。

Changed

• use() 同名防重: 同名插件重复安装时 warn 并跳过（unuse 后可重新安装），消除全局插件与 config.plugins 重复安装问题。

Added

• 回归测试 19 个（脚注注入 / 全局插件 / 缓存指纹 / underline / getStatus locale / replaceAll $ / use 防重），总数 782 → 801。

---

[0.2.5] - 2026-08-09

Fixed

• npm 发布配置: module / exports.import 不再指向 TS 源码，产物改用标准 .mjs / .cjs 扩展名（此前 "type": "module" 导致 Node 将 .js 产物按 ESM 解析，require() 拿不到任何导出）。
• XSS 属性注入: 链接/图片的 href/src/alt/title 及代码块 language-* 类与标题属性现经属性级转义（escapeHTML 在浏览器环境不转义双引号，此前的属性拼接存在注入面）。
• 本地存储串扰: 分隔条比例键改为 metona-editor-divider-${id}，多实例互不覆盖。

Added

• maxLength 生效: 之前仅有类型与默认值，现绑定 textarea maxlength 并对 setValue / insert / replaceAll / replaceAllRegex 截断。
• zenMode 初始状态: 配置 zenMode: true 启动即进入专注模式（此前仅 toggleZen() 可进入）。
• 搜索面板大小写 / 全字匹配: matchCase / wholeWord 翻译键此前存在但未实现，现补齐 UI 开关与匹配逻辑（普通与正则模式均支持，中文全字边界感知）。
• 内置轻量语法高亮: 新模块 src/highlight.ts，零依赖 tokenizer，13 种语言，MeEditor.highlight 即插即用，输出 me-hl-* 类。
• exportPDF: exportTool 新增 editor.exportPDF()（隐藏 iframe + window.print）。
• imagePaste 尺寸限制: editor.use('imagePaste', { maxSizeKB: 500 })，超限 toast 警告。
• 性能基准: npm run bench（parseMarkdown 1MB ≈ 51ms，highlight 200 函数 ≈ 1.2ms）。

Changed

• core.ts 拆分: 命令、浮动工具栏、右键菜单、大纲 4 组方法拆至独立模块（commands.ts / floating-toolbar.ts / context-menu.ts / outline.ts），core 从 1162 行降至 865 行，API 完全兼容。
• 插件状态类型收紧: 6 个预设插件的实例状态改用 Symbol 键存储（EditorLike 接口 + pluginState 助手），消灭 (editor as any).__xxx 魔法属性。
• eslint type-aware: 启用 parserOptions.project 与 consistent-type-imports / no-unnecessary-type-assertion 规则，0 errors。
• CI 并行化: 测试拆分为 parser / core / rest 三个并行 job，另设跨 Node 18/20/24 的 verify job（typecheck + lint + build）。
• docs.html / README 补齐: 光标选区 API、浮动工具栏、replaceAll、新事件、内置高亮文档。
• 版本同步 0.2.4 → 0.2.5，测试 725 → 768。

---

---

• Floating format toolbar: Auto-shows bold/italic/code/link/strikethrough buttons above text selection.
• Cursor/selection APIs: getSelectedText(), getCursorPosition(), setCursorPosition(), scrollToLine(), selectLine(), selectAll().
• Content manipulation APIs: replaceAll(), replaceAllRegex(), lineCount(), getLine().
• New events: selectionChange and cursorMove emitted for cursor/selection tracking.
• floatingToolbar config option: Enable/disable floating toolbar (default true).

Changed

• floatingToolbar added to DEFAULTS and EditorOptions type.

• Table auto-format: exec('formatTable') aligns column widths in Markdown tables.
• Code block title: ```js title=hello.js renders a styled title bar above code blocks.
• Escaped pipe in tables: \| in table cells no longer splits columns.
• Custom block token fallback render: Unknown token types now render as <div class="me-block-{type}"> instead of empty string.
• Gutter incremental update: Line number gutter uses DOM diff instead of full innerHTML replacement.

Changed

• All 6 plugins now use closure-based state — searchReplace, imagePaste, shortcutHelp, fileSystem, autoSave refactored for thread safety.
• shortcutHelp plugin is now i18n-aware — shortcut descriptions follow the active locale.

• 684 tests (up from 610), 9 test suites (up from 7).

Changed

• autoSave plugin refactored: Uses closure-based state per instance instead of this context, preventing state conflicts when the same plugin object is shared across multiple editors.
• Plugin install() now receives options as second argument for cleaner API.
• RTL locale detection improved: Now detects RTL by language prefix (e.g., ar-SA → RTL).

Fixed

• Reference link syntax [text][ref] now correctly resolves to links instead of raw text.
