| 7 | Package mergo merges same-type structs and maps by setting default values in zero-value fields. |
| 8 | |
| 9 | Mergo won't merge unexported (private) fields but will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection). |
| 10 | |
| 11 | Usage |
| 12 | |
| 13 | From my own work-in-progress project: |
| 14 | |
| 15 | type networkConfig struct { |
| 16 | Protocol string |
| 17 | Address string |
| 18 | ServerType string `json: "server_type"` |
| 19 | Port uint16 |
| 20 | } |
| 21 | |
| 22 | type FssnConfig struct { |
| 23 | Network networkConfig |
| 24 | } |
| 25 | |
| 26 | var fssnDefault = FssnConfig { |
| 27 | networkConfig { |
| 28 | "tcp", |
| 29 | "127.0.0.1", |
| 30 | "http", |
| 31 | 31560, |
| 32 | }, |
| 33 | } |
| 34 | |
| 35 | // Inside a function [...] |
| 36 | |
| 37 | if err := mergo.Merge(&config, fssnDefault); err != nil { |
| 38 | log.Fatal(err) |
| 39 | } |
| 40 | |
| 41 | // More code [...] |
| 42 | |
