Env var is not unmarshalled

[vasily-kirichenko]

I guess I'm missing something. Why EXE_PATH field is not assigned during unmarshalling?

package main

import (
	"fmt"
	"github.com/spf13/viper"
	"log"
	"os"
)

type Config struct {
	EXE_PATH string
}

func main() {
	if err := os.Setenv("EXE_PATH", "exe path from env"); err != nil {
		log.Fatal(err)
	}
	viper.AutomaticEnv()
	var cfg Config
	if err := viper.Unmarshal(&cfg); err != nil {
		log.Fatal(err)
	}
	fmt.Printf("EXE_PATH: %v\n", viper.Get("EXE_PATH"))
	fmt.Printf("%#v\n", cfg)
}

EXE_PATH: exe path from env
main.Config{EXE_PATH:""}
