confy is a lightweight configuration module for your app. It's quite simple and easy to use.
// confy supports 6 kinds of type as following:
confy.Define("http.host", "127.0.0.1") // Text
confy.Define("http.port", 3389) // Integer
confy.Define("http.max.memory.rate", 66.6) // Float
confy.Define("http.auth.enabled", true) // Boolean
confy.Define("app.terminal.date", time.Now()) // time.Time
confy.Define("app.refresh.interval", time.Second*12) // time.Duration
// load configuration from local file or remote site.
// meanwhile, start a deamon for auto refreshing.
confy.Ready()
// print confy value
fmt.Printf("http.host:[%s]", confy.Text("http.host"))
fmt.Printf("http.port:[%d]", confy.Int("http.port"))
fmt.Printf("max.memory.rate:[%f]", confy.Float("http.max.memory.rate"))
fmt.Printf("auth.enabled:[%v]", confy.Bool("http.auth.enabled"))
fmt.Printf("terminal.date:[%v]", confy.Time("app.terminal.date"))
