Types

type Locale

type Locale interface {
	// Tr translates a given key and arguments for a language
	Tr(trKey string, trArgs ...interface{}) string
	// Has reports if a locale has a translation for a given key
	Has(trKey string) bool
}

func GetLocale

func GetLocale(lang string) (Locale, bool)

GetLocales returns the locale from the default locales

type LocaleStore

type LocaleStore interface {
	io.Closer

	// Tr translates a given key and arguments for a language
	Tr(lang, trKey string, trArgs ...interface{}) string
	// Has reports if a locale has a translation for a given key
	Has(lang, trKey string) bool
	// SetDefaultLang sets the default language to fall back to
	SetDefaultLang(lang string)
	// ListLangNameDesc provides paired slices of language names to descriptors
	ListLangNameDesc() (names, desc []string)
	// Locale return the locale for the provided language or the default language if not found
	Locale(langName string) (Locale, bool)
	// HasLang returns whether a given language is present in the store
	HasLang(langName string) bool
	// AddLocaleByIni adds a new language to the store
	AddLocaleByIni(langName, langDesc string, source, moreSource []byte) error
}

LocaleStore provides the functions common to all locale stores

func NewLocaleStore

func NewLocaleStore() LocaleStore
