# Code Understanding Inspect symbols without reading source files. ## runectl lsp hover Get hover info for a symbol — type signature and doc comments. ``` Usage: runectl lsp hover (<file> <line> <col> | <symbol>) [flags] Flags: -F, --format string Output format: table, json, or Go template ``` Use to understand what a symbol is without finding and reading its definition. Example — inspect the `workspaceapi.Cmd` type: ```bash $ runectl lsp hover workspaceapi.Cmd ```go type Cmd struct { // size=152 (0x98), class=160 (0xa0) Path string Dir string Args []string Env []string Stdin io.Reader Stdout io.Writer Stderr io.Writer Watcher ProcessWatcher // SysProcAttr is ignored if passed from a extension. SysProcAttr *syscall.SysProcAttr } ``` --- Cmd represents an external command being prepared to run... ``` Returns the full type signature and doc comment rendered as markdown. This gives you the complete struct layout without reading the source file. ## runectl lsp signature-help Get signature help at a position — parameter names and types. ``` Usage: runectl lsp signature-help <file> <line> <col> [flags] Flags: -F, --format string Output format: table, json, or Go template ``` Position must be inside a function call's argument list. Use to know a function's parameters without reading its definition. ## runectl lsp completion Get completion suggestions at a position. ``` Usage: runectl lsp completion <file> <line> <col> [flags] Flags: -F, --format string Output format: table, json, or Go template ``` Returns label, kind, and detail for each completion item. Use to discover available methods and fields on a type.
