分析完一个featureCommands后，其他的22个都是类似的。它们的作用是将编辑器对源码的操作接口进行标准化，它的核心接口如下：‌

‌文本同步‌
textDocument/didOpen
、textDocument/didChange
、textDocument/didClose
‌代码补全‌
textDocument/completion
‌定义跳转‌
textDocument/definition
、textDocument/typeDefinition
‌引用查找‌
textDocument/references
‌符号搜索‌
textDocument/documentSymbol
、workspace/symbol
‌代码诊断‌
textDocument/publishDiagnostics
‌代码格式化‌
textDocument/formatting
、textDocument/rangeFormatting

gopls除了实现上述标准接口外还实现了Go 语言特有扩展接口‌

‌代码生成‌
textDocument/codeAction
（支持生成测试、实现接口等）
‌重构操作‌
textDocument/rename
、textDocument/prepareRename
‌语义令牌‌
textDocument/semanticTokens/full
（增强语法高亮）
‌工作区模块管理‌
workspace/executeCommand
（go.mod
依赖操作）

除此之外还实现了一系列其他能力：

‌ 内部核心接口（非 LSP 标准）‌

‌缓存管理‌
View
（文件快照）、Snapshot
（模块状态缓存）
‌类型检查‌
Package
（集成 go/types
和 x/tools/go/packages
）
‌代码分析‌
Analyzer
（静态检查规则，如 nilness
、unused
）

‌ 工具链集成接口‌

‌构建系统交互‌
解析 go/build
和 go list
输出
‌调试支持‌
Debug
端点（如 gopls/check_updates
）
server的接口定义位于internal/protocol/tsserver.go
