EnvSet

Tiny package to populate your structs from environment variables.

Usage

Install it:

go get github.com/dmytro-vovk/envset

Import it:

import "github.com/dmytro-vovk/envset"

Use it:

1. Define your structure, e.g:

type MyConfig struct {
	Webserver struct {
		Listen string `env:"LISTEN" default:":8080"`
	}
	Logfile string `env:"LOG_FILE"`
}

2. Create a variable of your type:

var config &MyConfig 

3. Call the package to populate the variable:

if err := envset.Set(&config); err != nil {
	log.Fatalf("Error setting config from environment: %s", err)
}

4. Set environment variables and run your app:

LISTEN="localhost:8088" LOG_FILE="/tmp/my_app.log" go run main.go
