一个跨平台的ChatGPT悬浮窗工具
使用avalonia实现的ChatGPT的工具，设计成悬浮窗，并且支持插件。
如何实现悬浮窗？
在使用avalonia实现悬浮窗也是非常的简单的。
实现我们需要将窗体设置成无边框
在Window根节点添加一下属性，想要在Linux下生效请务必添加SystemDecorations属性
ExtendClientAreaToDecorationsHint="True"
ExtendClientAreaChromeHints="NoChrome"
ExtendClientAreaTitleBarHeightHint="-1"
SystemDecorations="None"
这样我们的窗口就设置成了无边框。
然后我们还需要将窗体的大小固定，
Height="50"
MaxHeight="50"
Width="{Binding Width}"
MaxWidth="{Binding Width}"
高度固定，宽度绑定到ViewModel的Width属性中，默认270，
接下来给出所有代码，

只需要设置无边框并且固定大小。悬浮窗的效果就达到了。
我们看看执行效果
就这样简单的悬浮窗写好了，我们使用一下悬浮窗的搜索功能
这个就是简单的使用效果，对比其他的工具，这个悬浮窗更简洁，并且跨平台和开源。
目前的项目结构。
plugin下面的项目是默认的插件，用于搜索系统文件（未完善）
Gotrays.Suspension.Client则是实际的客户端。
Gotrays.Suspension.PlugIn则是插件定义的接口规范。
Gotrays.Update则是检查更新程序，用于更新主程序。
实现插件
plug-in
插件模块，用于扩展功能。
插件开发
1. 创建插件项目
在解决方案中创建一个类库项目，项目名称以Gotrays.Suspension.PlugIn.开头，例如Gotrays.Suspension.PlugIn.Test。
然后在项目中依赖Gotrays.Suspension.PlugIn类库。
2. 创建插件类
在项目中创建一个类，继承Gotrays.Suspension.PlugIn.PlugInBase类，例如：
using Gotrays.Suspension.PlugIn;
public class SystemTools : PlugInBase
{
public SystemTools()
{
Name = "系统搜索";
// 获取system.png嵌入资源的Stream
var stream = GetType().Assembly.GetManifestResourceStream("SystemTools.system.png");
if (stream == null) return;
// 读取Stream到byte数组
var bytes = new byte[stream.Length];
var read = stream.Read(bytes, 0, bytes.Length);
Icon = bytes;
}
// 搜索触发
public override async Task SearchAsync(string value)
{
// 打开系统搜索
Process.Start("explorer.exe", "search://" + value);
await Task.CompletedTask;
}
protected override async Task InitAsync(IServiceCollection services){
// 插件首次加载时执行
}
public override async Task BuilderServiceAsync(IServiceProvider provider)
{
// 这里可以得到服务提供者，可以通过服务提供者获取其他服务
}
protected override void Selection()
{
// 当插件被选中时执行
}
protected override void UnSelection()
{
// 当插件被取消选中时执行
}
protected override async Task UnloadAsync()
{
// 当插件被卸载插件发生
}
}
工具服务会进行自动发现，无需手动注册。
只需要将程序集放置在./plug-in目录下即可。
服务会在一个程序集中发现所有的插件类，并且进行注册。
按照上面的方式非常的简单就集成了插件。
