goConfig

goConfig uses a struct as input and populates the fields of this struct with parameters fom command line, environment variables and configuration file.

Install

go get github.com/crgimenes/goConfig

Example

package main

import "fmt"
import "github.com/crgimenes/goConfig"

type mongoDB struct {
	Host string `cfgDefault:"example.com"`
	Port int    `cfgDefault:"999"`
}

type configTest struct {
	Domain  string
	MongoDB mongoDB
}

func main() {
	config := configTest{}
	err := goConfig.Parse(&config)
	if err != nil {
		fmt.Println(err)
		return
	}

	fmt.Printf("\n\n%#v\n\n", config)
}

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.
