Reading Config Files

Owl requires minimal configuration so it knows where to look for config files. Owl just supports YAML file.

Examples:

owl.SetConfName("test.yaml")
owl.AddConfPath("./mock/")
err := owl.ReadConf()
if err != nil { // Handle errors reading the config file
  panic(fmt.Errorf("Fatal error config file: %s \n", err))
}

In owl, there are a few ways to get a value depending on the value’s type. The following functions and methods exist:

• Get(key string) : interface{}
• GetBool(key string) : bool
• GetFloat64(key string) : float64
• GetInt(key string) : int
