if file parse err no config read at all

[nevian427]

Hi,

If file doesn't exists or corrupted - nothing got at all. TOML/ENV can be empty (null) to be ok all others - fail.
Expected to get params from env and/or default env

package main

import (
	"github.com/ilyakaznacheev/cleanenv"
	"github.com/spf13/pflag"
	"github.com/davecgh/go-spew/spew"
)

type Config struct {
	BindAddr   string `toml:"bindaddr" env:"YAACC_BINDADDR" env-default:":5013"`
	DBPort     int    `toml:"dbport" env:"YAACC_DBPORT" env-default:"5432"`
	DBHost     string `toml:"dbhost" env:"YAACC_DBHOST" env-default:"localhost"`
	DBName     string `toml:"dbname" env:"YAACC_DBNAME" env-default:"postgres"`
	DBUser     string `toml:"dbuser" env:"YAACC_DBUSER" env-default:"cdr"`
	DBPassword string `toml:"dbpassword" env:"YAACC_DBPASSWORD"`
	Logfile    string `toml:"logfile"`
}

func main() {
	cfgfile := pflag.StringP("config", "c", "./yaacc.toml", "File to read config params from")
	logfile := pflag.StringP("logfile", "l", "", "File to write exec time messages.")
	pflag.Lookup("logfile").NoOptDefVal = "./yaacc.log"
	pflag.Parse()

	jww.SetPrefix("yaacc")
	jww.SetLogThreshold(jww.LevelTrace)
	jww.SetStdoutThreshold(jww.LevelInfo)

	err := cleanenv.ReadConfig(*cfgfile, &cfg)
	if err != nil {
		jww.WARN.Printf("Error loading config (%s): %q", *cfgfile, err)
	}
	spew.Dump(cfg)
}

Agree. Would be great to get this working even in absence of a yaml file!

I have that problem. I thought when there is no yaml config file it would get values from env or env-default, but it is not.
