## 依赖
|
||||
DESCRIPTION
|
||||
-----------
|
||||
**tut** is a text-mode web browser designed for comfortable reading in the
|
||||
terminal. It extracts and displays the textual content of web pages with a
|
||||
clean, centered layout optimized for reading, while providing vim-style
|
||||
keyboard navigation.
|
||||
|
||||
- CMake ≥ 3.15
|
||||
- C++17 编译器（macOS 建议 clang，Linux 建议 g++）
|
||||
- `ncurses` 或 `ncursesw`（支持宽字符）
|
||||
- `libcurl`（支持HTTPS）
|
||||
The browser does not execute JavaScript or display images. It is designed
|
||||
for reading static HTML content, documentation, and text-heavy websites.

LIMITATIONS
|
||||
-----------
|
||||
**tut** does not execute JavaScript. Modern single-page applications (SPAs)
|
||||
built with React, Vue, Angular, or similar frameworks will not work correctly,
|
||||
as they require JavaScript to render content.
|
||||
|
||||
To determine if a site will work with **tut**, use:
|
||||
|
||||
curl https://example.com | less
|
||||
|
||||
If you can see the actual content in the HTML source, the site will work.
|
||||
If you only see JavaScript code or empty div elements, it will not.
|
||||
|
||||
Additionally:
|
||||
- No image display
|
||||
- No CSS layout support
|
||||
- No form submission
|
||||
- No cookie or session management
|
||||
- No AJAX or dynamic content loading

|
||||
PHILOSOPHY
|
||||
----------
|
||||
**tut** follows the Unix philosophy:
|
||||
|
||||
### 搜索
|
||||
1. Do one thing well: display and navigate text content from the web.
|
||||
2. Work with other programs: output can be piped, URLs can come from stdin.
|
||||
3. Simple and minimal: no configuration files, no persistent state.
|
||||
4. Text-focused: everything is text, processed and displayed cleanly.
|
||||
|
||||
| 按键 | 功能 |
|
||||
|------|------|
|
||||
| `/` | 开始搜索 |
|
||||
| `n` | 下一个匹配 |
|
||||
| `N` | 上一个匹配 |
|
||||
The design emphasizes keyboard efficiency, clean output, and staying out
|
||||
of your way.
|
||||
|
||||
### 命令模式

||||

|
||||
--------
|
||||

|
||||
- 按 `Enter` 打开链接
|
||||
- 按 `h` 返回上一页
|
||||
|
||||
### 阅读文档
|
||||
|
||||
```bash
|
||||
./tut https://en.wikipedia.org/wiki/Unix
|
||||
```
|
||||
|
||||
然后：
|
||||
- 使用 `gg` 跳转到顶部
|
||||
- 使用 `/` 搜索关键词（如 `/history`）
|
||||
- 使用 `n/N` 在搜索结果间跳转
|
||||
- 使用 `Space` 翻页阅读
|
||||
|
||||
### 快速查看多个网页
|
||||
|
||||
```bash
|
||||
./tut https://github.com
|
||||
```
|
||||
|
||||
在浏览器内：
|
||||
- 浏览页面并点击链接
|
||||
- 使用 `:o https://news.ycombinator.com` 打开新URL
|
||||
- 使用 `h/l` 在历史中前进后退
|
||||
|
||||
## 设计理念
|
||||
|
||||
TUT 的设计目标是提供最佳的终端阅读体验：
|
||||
|
||||
1. **极简主义** - 只关注文本内容，摒弃图片、广告等干扰元素
|
||||
2. **高效操作** - 完全键盘驱动，无需触摸鼠标
|
||||
3. **优雅排版** - 自适应宽度，居中显示，类似专业阅读器
|
||||
4. **快速响应** - 轻量级实现，即开即用
|
||||
|
||||
## 架构
|
||||
|
||||
```
|
||||
TUT
|
||||
├── http_client - HTTP/HTTPS 网页获取
|
||||
├── html_parser - HTML 解析和文本提取
|
||||
├── text_renderer - 文本渲染和排版引擎
|
||||
├── input_handler - Vim 风格输入处理
|
||||
└── browser - 浏览器主循环和状态管理
|
||||
```
|
||||
|
||||
## 限制
|
||||
|
||||
### JavaScript/SPA 网站
|
||||
**重要：** 这个浏览器**不支持JavaScript执行**。这意味着：
|
||||
|
||||
- ❌ **不支持**单页应用(SPA)：React、Vue、Angular、Astro等构建的现代网站
|
||||
- ❌ **不支持**动态内容加载
|
||||
- ❌ **不支持**AJAX请求
|
||||
- ❌ **不支持**客户端路由
|
||||
|
||||
**如何判断网站是否支持：**
|
||||
1. 用 `curl` 命令查看HTML内容：`curl https://example.com | less`
|
||||
2. 如果能看到实际的文章内容，则支持；如果只有JavaScript代码或空白div，则不支持
|
||||
|
||||
**你的网站示例：**
|
||||
- ✅ **thinker.m1ng.space** - 静态HTML，完全支持，可以浏览文章列表并点击进入具体文章
|
||||
- ❌ **blog.m1ng.space** - 使用Astro SPA构建，内容由JavaScript动态渲染，无法正常显示
|
||||
|
||||
**替代方案：**
|
||||
- 对于SPA网站，查找是否有RSS feed或API端点
|
||||
- 使用服务器端渲染(SSR)版本的URL（如果有）
|
||||
- 寻找使用传统HTML构建的同类网站
|
||||
|
||||
### 其他限制
|
||||
|
||||
- 不支持图片显示
|
||||
- 不支持复杂的CSS布局
|
||||
- 不支持表单提交
|
||||
- 不支持Cookie和会话管理
|
||||
- 专注于内容阅读，不适合需要交互的网页
|
||||
|
||||
## 开发指南
|
||||
|
||||
### 代码风格
|
||||
|
||||
- 遵循 C++17 标准
|
||||
- 使用 RAII 进行资源管理
|
||||
- 使用 Pimpl 模式隐藏实现细节
|
||||
|
||||
### 测试
|
||||
|
||||
```bash
|
||||
cd build
|
||||
./tut https://example.com
|
||||
```
|
||||
|
||||
### 贡献

|
||||
|
||||
1. 代码风格与现有代码一致

||||
2. 添加必要的注释
|
||||
3. 测试新功能

||||
4. 更新文档
|
||||
