# config/scan
Return a map of all registry entries whose key starts with the given prefix. Used to read one app's slice of the registry at once.
## Syntax
[config/scan "prefix"]
## Parameters
- `"prefix"` — key prefix to match (e.g. `"log/"`, `"editor."`). Pass `""` to scan every entry.
## Examples
[config/scan "log/"] [config/scan "editor."] [config/scan ""] # everything
## Returns
Map of `keyword → value`. Keys come back as keywords (canonical map-key form); values are parsed from their stringified form.
