将 AI CLI 响应与 Python PySide6 桌面应用程序进行并排比较
在只能一次测试一个AI编码助手的情况下，选择合适的工具并非易事。安装了Qwen Code、GitHub Copilot CLI、OpenCode和Gemini CLI的开发者需要一种快速的方法，将相同的提示信息同时发送给它们，并并行读取结果。本项目使用PySide6构建了一个Python桌面应用程序，它能够实现这一目标——输入一个提示信息，即可同时输出四个实时响应面板。
你将构建：一个 PySide6 桌面 GUI，它可以动态检测已安装的 AI CLI 工具，同时向所有这些工具发送一个提示，并将每个响应流式传输到它自己的面板中，并提供 Markdown/渲染 HTML 切换选项以便于阅读。
先决条件
- Python 3.10+
- PySide6（
pip install PySide6） - markdown (
pip install markdown) - 至少安装并验证了以下一种 AI CLI 工具：
| 命令行界面 | 安装命令 | 文档 |
|---|---|---|
| Qwen Code | npm install -g @qwen-code/qwen-code |
github.com/QwenLM/qwen-code |
| GitHub Copilot CLI | npm install -g @github/copilot |
docs.github.com |
| OpenCode | npm install -g opencode-ai |
opencode.ai |
| Gemini CLI | npm install -g @google/gemini-cli |
github.com/google-gemini/gemini-cli |
安装依赖项
创建requirements.txt包含两个 Python 依赖项的文件并安装它们：
<span style="color:#212529"><span style="color:#333333"><span style="background-color:#eaeaea"><code>PySide6>=6.6.0
markdown>=3.5
</code></span></span></span><span style="color:#212529"><span style="color:#333333"><span style="background-color:#eaeaea"><code>pip <span style="color:#336666">install</span> <span style="color:#330099"><strong>-r</strong></span> requirements.txt
</code></span></span></span>定义 CLI 工具注册表
每个 AI CLI 都有自己的二进制名称、非交互式调用标志和品牌颜色。应用程序将这些信息存储为字典列表，以便在启动时动态生成面板。

</code></span></span></span>关键设计决策：
stdin=subprocess.DEVNULL防止 CLI 工具在交互式提示符处阻塞。stderr=subprocess.STDOUT将错误输出合并到面板中，这样就不会悄无声息地丢失任何信息。- 逐行迭代（
readline）实现了实时流式传输，而无需等待进程完成。
使用 Markdown 渲染构建每个 CLI 的响应面板
每个元素CLIPanel都QFrame包含一个头部（命令行名称、切换按钮、状态指示器）和两个堆叠的内容区域——一个等宽纯文本视图和一个渲染后的 HTML 视图。切换按钮用于在两者之间切换：
