Environment variable loader

Why use this over os.Getenv("FOO")? Read below to find out!

This package will load an environment variable file (usually a .env file placed in the root) and have these variables globally available using env.Get("FOO"). You can optionally allow 'real' environment variables to override the variables in the .env file allowing for some nice defaults to be set in the case of a missing environment variable.

What's more, unlike other env loaders, the variables contained in your .env file do not actually get set in the real environment and are only available to the running Go application making them more secure to malicious code that may be running on the same server.

Using env.Get("XXX") can completly replace os.Getenv("XXX") if there is no variable in the file then next check will be the 'real' environment.

Usage

go get github.com/SamuelBanksTech/Go-Environment

Basic Example

package main

import (
	"fmt"
    "log"
	"github.com/SamuelBanksTech/Go-Environment"
)

func main() {

	//Init env vars
	envinit := env.Environment{
		EnvPath:             ".env",
		EnableOsEnvOverride: true,
		HideOutput:          false,
	}

	err := envinit.LoadEnv()
	if err != nil {
		log.Fatalln(err)
	}
	
	fmt.Println(env.Get("FOO"))
	
}

Example .env

FOO=bar
BAR=donk
#IGNOREDVAR=foobar
