Functions

func ParseBool

func ParseBool(val interface{}) (value bool, err error)

ParseBool returns the boolean value represented by the string.

It accepts 1, 1.0, t, T, TRUE, true, True, YES, yes, Yes,Y, y, ON, on, On, 0, 0.0, f, F, FALSE, false, False, NO, no, No, N,n, OFF, off, Off. Any other value returns an error.

func Register

func Register(name string, adapter Config)

Register makes a config adapter available by the adapter name. If Register is called twice with the same name or if driver is nil, it panics.

Types

type Config

type Config interface {
	Parse(key string) (Configer, error)
	ParseData(data []byte) (Configer, error)
}

Config is the adapter interface for parsing config file to get raw data to Configer.

type Configer

type Configer interface {
	Set(key, val string) error   //support section::key type in given key when using ini type.
	String(key string) string    //support section::key type in key string when using ini and json type; Int,Int64,Bool,Float,DIY are same.
	Strings(key string) []string //get string slice
	Int(key string) (int, error)
	Int64(key string) (int64, error)
	Bool(key string) (bool, error)
	Float(key string) (float64, error)
	DefaultString(key string, defaultVal string) string      // support section::key type in key string when using ini and json type; Int,Int64,Bool,Float,DIY are same.
	DefaultStrings(key string, defaultVal []string) []string //get string slice
	DefaultInt(key string, defaultVal int) int
	DefaultInt64(key string, defaultVal int64) int64
	DefaultBool(key string, defaultVal bool) bool
	DefaultFloat(key string, defaultVal float64) float64
	DIY(key string) (interface{}, error)
	GetSection(section string) (map[string]string, error)
	SaveConfigFile(filename string) error
}
