Envirotron

Ever wanted to easily allow users to override configuration values in a Go program via environment variables, but didn't want to deal with the tedium of checking that variables are set, and the harrowing existential crisis of determing what is true?

Want no more!

package thing

import (
  "fmt"
  env "github.com/jhunt/go-envirotron"
)

type Config struct {
  URL      string `env:"THING_URL"`
  Username string `env:"THING_USERNAME"`
  Password string `env:"THING_PASSWORD"`
}

func main() {
  c := Config{}
  env.Override(&c)

  fmt.Printf("connecting to %s, as %s\n", c.URL, c.Username)
}

Happy Hacking!
