# config
[](https://tldrlegal.com/license/mit-license)
config uses a struct as input and populates the fields of this struct with parameters from command line, environment variables and configuration file.
## Install
```
go get crg.eti.br/go/config
```
## Example
```go
package main
import "crg.eti.br/go/config"
/*
step 1: Declare your configuration struct,
it may or may not contain substructures.
*/
type mongoDB struct {
Host string `cfgDefault:"example.com" cfgRequired:"true"`
Port int `cfgDefault:"999"`
}
type configTest struct {
Domain string
DebugMode bool `json:"db" cfg:"db" cfgDefault:"false"`
MongoDB mongoDB
IgnoreMe string `cfg:"-"`
}
func main() {
// step 2: Instantiate your structure.
config := configTest{}
// step 3: Pass the instance pointer to the parser
err := config.Parse(&config)
if err != nil {
println(err)
return
}
/*
The parser populated your struct with the data
it took from environment variables and command
line and now you can use it.
*/
println("config.Domain......:", config.Domain)
println("config.DebugMode...:", config.DebugMode)
println("config.MongoDB.Host:", config.MongoDB.Host)
println("config.MongoDB.Port:", config.MongoDB.Port)
}
```
With the example above try environment variables like *$DOMAIN* or *$MONGODB_HOST* and run the example again to see what happens.
You can also try using parameters on the command line, try -h to see the help.
