A small configuration library for Go that parses environment variables, JSON files, and reloads automatically on SIGHUP.

func main() {
	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		var value string
		config.Get("config.json", "value", &value)
		fmt.Fprintf(w, "Value: %s", value)
	})

	http.ListenAndServe(":3000", nil)
}

func Get(file, key string, v interface{}) error

Takes the path to a JSON file, the name of the configuration option, and a pointer to the variable where the config value will be stored. v can be a pointer to a string, bool, or float64.

func Reload()

Reloads the config. Happens automatically on SIGHUP.
