A converter between struct and other data.
## Installation
```shell
go get -u github.com/twihike/go-structconv
```
## Usage
`structconv.DecodeMap`
```go
package main
import (
"fmt"
"github.com/twihike/go-structconv/structconv"
)
type example1 struct {
A int `map:"AA,required"`
B []example2
}
type example2 struct {
C int
D string
E string `map:"-"` // Omitted.
}
func main() {
var e example1
structconv.DecodeMap(map[string]interface{}{
"AA": 1,
"B": []map[string]interface{}{
{
"C": 2,
"D": "foo",
"E": "FOO",
},
{
"C": 3,
"D": "bar",
"E": "BAR",
},
},
}, &e, nil)
fmt.Println(e) // {1 [{2 foo } {3 bar }]}
}
```
`structconv.DecodeStringMap`
```go
package main
import (
"fmt"
"github.com/twihike/go-structconv/structconv"
)
type config struct {
AppName string `strmap:",required"`
AppPort int
DB db
}
type db struct {
Host string `strmap:"DBHost,required"`
Username int `strmap:"DBUsername,required"`
Password string `strmap:"-"` // Omitted.
}
func main() {
m := map[string]string{
"AppName": "myapp",
"AppPort": "8080",
"DBHost": "mydb",
"DBUsername": "1234",
"DBPassword": "mypw",
}
var conf config
conf.AppPort = 80 // Default value.
err := structconv.DecodeStringMap(m, &conf, nil)
if err != nil {
fmt.Println(err)
}
fmt.Println(conf) //{myapp 8080 {mydb 1234 }}
}
```
`structconv.DecodeEnv`
```shell
export APP_NAME=awesomeapp
export PORT=8080
export DB_HOST=mydb
export DB_USERNAME=1234
export DB_PASSWORD=mypw
```
```go
package main
import (
"fmt"
"github.com/twihike/go-structconv/structconv"
)
type config struct {
AppName string `env:",required"`
AppPort int `env:"PORT"`
DB db
}
type db struct {
Host string `env:"DB_HOST,required"`
Username int `env:"DB_USERNAME,required"`
Password string `env:"-"` // Omitted.
}
func main() {
var conf config
conf.AppPort = 80 // Default value.
err := structconv.DecodeEnv(&conf, nil)
if err != nil {
fmt.Println(err)
}
fmt.Println(conf) // {awesomeapp 8080 {mydb 1234 }}
}
```
