English | 日本語

This is a package for getting environment variables with arbitrary types.

example

import (
	"fmt"
	"github.com/ieee0824/getenv"
	"time"
	"os"
)


fmt.Println(getenv.Duration("ANY_ENV"))
fmt.Println(getenv.Duration("ANY_ENV", 60))
fmt.Println(getenv.Duration("ANY_ENV","120s"))
fmt.Println(getenv.Duration("ANY_ENV", 60 * time.Second))
fmt.Println(getenv.Duration("ANY_ENV", "1h30m20s"))

os.Setenv("ANY_ENV", "60h")
fmt.Println(getenv.Duration("ANY_ENV"))
fmt.Println(getenv.Duration("ANY_ENV", 60))
fmt.Println(getenv.Duration("ANY_ENV","120s"))
fmt.Println(getenv.Duration("ANY_ENV", 60 * time.Second))
fmt.Println(getenv.Duration("ANY_ENV", "1h30m20s"))

os.Setenv("ANY_ENV", "60h")
fmt.Println(getenv.Duration("ANY_ENV"))
fmt.Println(getenv.Duration("ANY_ENV", 60))
fmt.Println(getenv.Duration("ANY_ENV","120s"))
fmt.Println(getenv.Duration("ANY_ENV", 60 * time.Second))
fmt.Println(getenv.Duration("ANY_ENV", "1h30m20s"))
