|
||||
|
||||
Go library for deep merging YAML or JSON files.
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
### YAML
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/TwiN/deepmerge"
|
||||
)
|
||||
|
||||
func main() {
|
||||
dst := `
|
||||
debug: true
|
||||
client:
|
||||
insecure: true
|
||||
users:
|
||||
- id: 1
|
||||
firstName: John
|
||||
lastName: Doe
|
||||
- id: 2
|
||||
firstName: Jane
|
||||
lastName: Doe`
|
||||
src := `
|
||||
client:
|
||||
timeout: 5s
|
||||
users:
|
||||
- id: 3
|
||||
firstName: Bob
|
||||
lastName: Smith`
|
||||
output, err := deepmerge.YAML([]byte(dst), []byte(src))
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
println(string(output))
|
||||
}
|
||||
```
|
||||
|
||||
Output:
|
||||
```yaml
|
||||
client:
|
||||
insecure: true
|
||||
timeout: 5s
|
||||
debug: true
|
||||
users:
|
||||
- firstName: John
|
||||
id: 1
|
||||
lastName: Doe
|
||||
- firstName: Jane
|
||||
id: 2
|
||||
lastName: Doe
|
||||
- firstName: Bob
|
||||
id: 3
|
||||
lastName: Smith
|
||||
```
|
||||
|
||||
### JSON
|
||||
```go
|
||||
package main
|
||||
|
||||

|
||||

|

|

|

|

if err != nil {
|

panic(err)
|
||||
}
|
||||
println(string(output))
|
||||

|

```
|

Output:
