Configuration Library

Usage

package main

import (
	"fmt"

	"github.com/libgolang/config"
)

func main() {
	config.AppName = "my-application"
	strFlag := config.String("flag-1", "default!", "Flag 1 usage")
	boolFlag := config.Bool("flag.2", false, "Flag 2 usage")
	config.Parse()

	fmt.Printf("flag-1: %s\n", *strFlag)
	fmt.Printf("flag.2: %t\n", *boolFlag)
}

The code will read configuration variables like in the following order:

• Command Line Argument
  • flag-1: -flag-1 value1 | -flag-1=value1 | --flag-1 value1 | --flag-1=value1
  • flag.2: -flag.2 value2 | -flag.2=value2 | --flag.2 value2 | --flag.2=value2
• Environment Variable
  • flag-1: FLAG_1=value1
  • flag.2: FLAG_2=value2
• Configuration File (my-application.properties)
  • flag-1: flag-1: value1
  • flag.2: flag.2: value2
• Default value provided in code
