Grabs environmental variables & maps them to your config type via struct tags
go get -u github.com/joegasewicz/env-conf
If an environment variable returns an empty string then the default config struct member will not be overridden.
os.Setenv("ENV_ONE", "apples")
os.Setenv("ENV_TWO", "bananas")
type Config struct {
EnvOne string `env_conf:"ENV_ONE"`
EnvTwo string `env_conf:"ENV_TWO"`
}
c := Config{}
err := env_conf.Update(&c)
fmt.Println("ENV_ONE: ", c.EnvOne) // applesUsing a : colon to set defaults,
the environment variable is on the left side & the default is on the right side.
type Config struct {
EnvOne string `env_conf:"ENV_ONE:http://127.0.0.1:8080"`
}
// If `ENV_ONE` does not exist then `EnvOne` will equal http://127.0.0.1:8080
