## Definition
|
||
Language Server Protocol（LSP）是微软提出的标准化协议，为编辑器/IDE 提供编程语言特性支持（自动补全、跳转定义、悬停文档等），实现语言功能与编辑器的解耦。
|
||
|
||
## Core Features
|
||
- **文本文档同步**：textDocument/didOpen、textDocument/didChange
|
||
- **代码导航**：textDocument/definition、textDocument/references、textDocument/documentSymbol
|
||
- **代码补全**：textDocument/completion
|
||
- **悬停文档**：textDocument/hover
|
||
- **诊断信息**：textDocument/publishDiagnostics
|
||
|
||
## LSP 3.17 Key Capabilities
|
||
- 能力协商机制（initialize 阶段交换 serverCapabilities）
|
||
- 完整生命周期管理（initialize → initialized → shutdown → exit）
|
||
- Workspace symbols 和 文件 URI 标准化
|
||
|
||
