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:
$ 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 [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 [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.
