Hi. Consider this example: https://play.golang.org/p/q7oEp40ZCIL
Unmarshal replaces the existing map entry with key "Postgres". The documentation says: To unmarshal a JSON object into a map, Unmarshal first establishes a map to use. If the map is nil, Unmarshal allocates a new map. Otherwise Unmarshal reuses the existing map, keeping existing entries. Unmarshal then stores key-value pairs from the JSON object into the map. The map's key type must either be a string, an integer, or implement encoding.TextUnmarshaler. Does the reported behavior conform to the documentation? Personally, I would have expected the program to not panic. Thanks Manlio Perillo -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
