feat(docs): add terminal introduction appendix with interactive components
Add a comprehensive terminal introduction guide with interactive Vue components demonstrating terminal concepts. Includes: - Terminal definition and architecture visualization - Character grid and cell inspector - ANSI escape sequences demo - Input visualization and signal mechanisms - Flow diagrams and TUI examples The components are registered in the VitePress theme and linked from the appendix section. Each component includes detailed documentation and interactive elements to help users understand terminal principles.

AdvancedTUIDemo.vue
|

高级 TUI 布局演示组件
|
||||
|
||||
用途：
|
||||
展示复杂的终端用户界面（Text User Interface）是如何构建的。
|
||||
说明如何利用备用缓冲区（Alternate Buffer）和全屏绘制技术来实现类似 vim/htop 的界面。
|
||||
|
||||
交互功能：
|
||||
- 布局展示：模拟一个包含侧边栏、主内容区和状态栏的 TUI 应用。
|
||||
- 动态更新：演示界面元素如何响应窗口大小变化或用户操作。

ArchitectureDemo.vue
|

终端架构演示组件
|
||||
|
||||
用途：
|
||||
可视化展示 Terminal（终端）、Shell（壳）和 Kernel（内核）之间的交互流程。
|
||||
通过模拟 "ls" 命令的执行过程，帮助用户理解输入传输、解析、系统调用、数据返回和渲染显示的完整链路。
|
||||
|
||||
交互功能：
|
||||
- 逐步演示 (Step-by-Step)：用户点击按钮一步步观察数据包流转。
|
||||
- 中英双语说明：适应不同语言背景的读者。
|
||||
- 状态反馈：实时显示各组件（终端/Shell/内核）的当前状态（空闲/忙碌）。

EscapeSequences.vue
|
||||
转义序列演示组件
|
||||
|
||||
用途：
|
||||
解释终端如何通过“不可见字符”来控制颜色、光标位置和清屏操作。
|
||||
揭示 ANSI 转义序列（如 `\033[31m`）的工作原理。
|
||||
|
||||
交互功能：
|
||||
- 颜色/样式按钮：点击后发送对应的转义序列。
|
||||
- 序列显示：实时显示当前发送的原始序列代码（如 `^[[31m`）。
|
||||
- 终端反馈：下方模拟终端根据接收到的序列改变文字颜色或清除内容。

输入输出流程图组件
|
||||
|
||||
用途：
|
||||
可视化展示一次按键从物理键盘到屏幕显示的完整“往返旅程” (Round Trip)。
|
||||
将复杂的系统流程（键盘 -> 操作系统 -> 终端 -> 程序 -> 终端 -> 屏幕）抽象为清晰的图表。
|
||||
|
||||
交互功能：
|
||||
- 静态展示：清晰的 SVG 或 CSS 流程图。
|
||||
- 节点说明：鼠标悬停可查看每个环节的具体解释。

用途：

展示键盘输入在底层是如何被转换为字节流发送给终端的。

交互功能：

- 数据展示：同时显示按键名、16进制字节码和转义序列（如方向键）。
|

# Terminal Intro Components
|
||||
|
||||
此目录包含 `docs/zh-cn/appendix/terminal-intro.md`（终端原理附录）页面使用的所有交互式 Vue 组件。
|
||||
|
||||
这些组件旨在通过可视化和互动的方式，帮助读者理解终端的工作原理、ANSI 转义序列、Shell 交互等概念。
|
||||
|
||||
## 组件列表
|
||||
|
||||
| 组件名 | 描述 | 对应文档章节 |
|
||||
| :--- | :--- | :--- |
|
||||
| **TerminalDefinition.vue** | 可视化终端作为“字符流输入/输出环境”的定义。展示键盘输入 -> 字符流 -> 屏幕输出的过程。 | 1. 概念界定 |
|
||||
| **ArchitectureDemo.vue** | 演示终端（前端）与 Shell（后端）的分离架构。模拟点餐流程类比。 | 2. 核心架构 |
|
||||
| **TerminalGrid.vue** | 展示终端的字符网格系统，演示行、列和单元格的概念。 | 3. 视觉模型 |
|
||||
| **CellInspector.vue** | 单元格检查器，展示每个字符单元格背后的属性（字符、前景色、背景色等）。 | 3.2 样式检查 |
|
||||
| **EscapeSequences.vue** | 演示 ANSI 转义序列如何控制颜色、样式、光标移动和清屏。 | 4. 通信协议 |
|
||||
| **InputVisualizer.vue** | 可视化键盘按键如何转换为字节序列发送给 Shell。 | 5. 输入机制 |
|
||||
| **WebTerminal.vue** | 一个功能较完整的模拟终端，支持 `ls`, `cd`, `cat`, `apt` 等命令，包含虚拟文件系统。 | 附录/综合演示 |
|
||||
| **SignalsDemo.vue** | 演示终端信号（如 Ctrl+C SIGINT）的工作机制。 | (文档中可能引用) |
|
||||
| **FlowDiagram.vue** | 展示标准输入/输出/错误流 (stdin/stdout/stderr) 的流向图。 | (文档中可能引用) |
|
||||
| **AdvancedTUIDemo.vue** | 展示基于文本的用户界面 (TUI) 的高级布局能力（如面板、进度条）。 | (文档中可能引用) |
|
||||
|
||||
## 开发指南
|
||||
|
||||
### 技术栈
|
||||
- **Vue 3**: 使用 `<script setup>` 语法。
|
||||
- **Styling**: Scoped CSS，主要使用 Flexbox 和 Grid 布局。
|
||||
- **Theme**: 统一使用黑色系背景 (`#09090b`, `#18181b`) 和 JetBrains Mono 字体，保持类似终端的视觉风格。
|
||||
|
||||
### 维护注意事项
|
||||
1. **双语支持**: 组件内部文本尽量支持中英双语，或通过 Props 传入文本。目前部分组件已硬编码双语标签。
|
||||
2. **自包含**: 组件应尽量自包含，不依赖外部复杂的 Store 或 Context，以便于在 Markdown 中直接使用。
|
||||
3. **响应式**: 考虑移动端适配，通常使用 `@media (max-width: 768px)` 进行布局调整。
|
||||
|
||||
### 常用颜色变量 (参考)
|
||||
- 背景: `#09090b` (Main), `#18181b` (Panel)
|
||||
- 边框: `#27272a`
|
||||
- 文本: `#e4e4e7` (Primary), `#a1a1aa` (Secondary)
|
||||
- 强调色: `#22c55e` (Green/Success), `#facc15` (Yellow/Warning), `#22d3ee` (Cyan/Info)
|
||||
|
||||
## 目录结构
|
||||
所有组件均位于 `docs/.vitepress/theme/components/appendix/terminal-intro/` 下。
|
||||
注册逻辑位于 `docs/.vitepress/theme/index.js`。

SignalsDemo.vue
|
||||
信号机制演示组件
|
||||
|
||||
用途：
|
||||
演示进程控制信号（Signals）如何工作，特别是 `Ctrl+C` 和 `Ctrl+Z`。
|
||||
说明这些组合键不是发送字符，而是触发操作系统级别的中断信号。
|
||||
|
||||
交互功能：
|
||||
- 模拟运行：点击按钮启动一个模拟进程（如 `sleep 100`）。
|
||||
- 发送信号：点击按钮或快捷键发送 SIGINT/SIGTSTP。
|
||||
- 状态反馈：展示进程状态的变化（运行中 -> 被杀死/被挂起）。

TerminalGrid.vue
|
||||
终端网格模型演示组件
|
||||
|
||||
用途：
|
||||
展示终端屏幕本质上是由“字符网格”构成的。
|
||||
帮助用户理解终端不是像素画板，而是由一个个固定大小的单元格（Cell）组成的矩阵。
|
||||
|
||||
交互功能：
|
||||
- 点击/拖拽：可以在网格上“画”出字符。
|
||||
- 键盘输入：可以直接在网格中打字，观察光标移动和字符填充。
|
||||
- 响应式布局：支持横向滚动，适应不同屏幕宽度。
