Personal project.

You can automatically load your environment variable into specific struct by using the tag env:"" and calling the function env.Unmarshal().

Note: The package doesn't check the validity of the data.

➡ install

go get github.com/kovacou/go-env

➡ usage

APP_TITLE=Titre de mon application
APP_VERBOSE=true
APP_KEYS=facebook:key1,google:key2,twitter:key3
APP_SLICE_KEYS=key1,key2,key3

package main

import (
    "github.com/kovacou/go-env"
)

type Config   struct {
    Title     string            `env:"APP_TITLE"`
    Verbose   bool              `env:"APP_VERBOSE"`
    Keys      map[string]string `env:"APP_KEYS"`
    SliceKeys []string          `env:"APP_SLICE_KEYS"`
}

func main() {
    cfg := Config{}
    env.Unmarshal(&cfg)
    // Config{
    //     Title:     "My Application",
    //     Verbose:   true,
    //     Keys:      {"facebook":"key1", "google":"key2", "twitter":"key3"},
    //     SliceKeys: {"key1", "key2", "key3"}
