# config

- Support to load the configurations

- Support to merge the environment variables to the configurations

- Support to override the configurations based on the environment (For example: SIT environment, UAT environment)

## Installation

Please make sure to initialize a Go module before installing core-go/config:

```shell

go get -u github.com/core-go/config

```

Import:

```go

import "github.com/core-go/config"

```

## Example

We have 2 config files, which are put into "configs" directory

- the default config file: config.yaml

- for SIT environment: config-sit.yaml

#### config.yaml

```yaml

ldap:

  server: localhost:389

  binding_format: uid=%s,ou=users,dc=sample,dc=com,dc=vn

redis_url: redis://localhost:6379

```

In the SIT environment, we just override the configuration of ldap server and redis server:

#### config-sit.yaml

```yaml

ldap:

  server: sit-server:389

redis_url: redis://redis-sit:6379

```

```go

type LDAPConfig struct {

	Server        string `mapstructure:"server"`

	BindingFormat string `mapstructure:"binding_format"`

}

type RootConfig struct {

	Server      app.ServerConfig `mapstructure:"server"`

	Ldap        LDAPConfig       `mapstructure:"ldap"`

	RedisClient string           `mapstructure:"redis_client"`

}

func main() {

	env := os.Getenv("ENV")

	var cfg RootConfig

	// "authentication" is the directory, which contains source code

	// "configs" is the directory, which contains config.yaml and config-sit.yaml 

	config.LoadConfigWithEnv("authentication", "configs", env, &cfg, "config")

	log.Println("config ", cfg)

	var conf2 RootConfig

	config.Load(&conf2, "configs/config")

	log.Println("config2 ", conf2)

}

```
