代码编辑器:代码补全、悬停提示、参数提示、边写边检查
- 运行器新增 language-server 模式:常驻语言服务,和编译服务分开;用 Roslyn 的
CompletionService、QuickInfoService(和 VS 的 IntelliSense 同一套引擎),参数提示用语义模型实现;
每个浏览器标签页一份工程,只更新有变化的文件;去掉仿真类库的可空注解(string? → string)
- 编译和语言服务共用同一套编译选项和引用;检查结果带上禁止 API 的报错和中文提示
- 服务端 POST /api/language 转发请求(按用户区分会话,10 秒超时)
- 编辑器:补全("." 触发,选中时取说明)、悬停、参数提示("(" "," 触发);停止输入 1 秒后检查整个工程,
和"运行"时的编译结果以较新的为准
- 实测(2 核):50 个标签页同时检查 1.2 秒内完成,同时补全 0.7 秒;内存约 260 MB
