Types

type LanguageFinder

type LanguageFinder func(*Translator, buffalo.Context) []string

LanguageFinder can be implemented for custom finding of search languages. This can be useful if you want to load a user's language from something like a database. See Middleware() for more information on how the default implementation searches for languages.

type Translator

type Translator struct {
	// Box - where are the files?
	Box packr.Box
	// DefaultLanguage - default is passed as a parameter on New.
	DefaultLanguage string
	// CookieName - name of the cookie to find the desired language.
	// default is "lang"
	CookieName string
	// SessionName - name of the session to find the desired language.
	// default is "lang"
	SessionName string
	// HelperName - name of the view helper. default is "t"
	HelperName     string
	LanguageFinder LanguageFinder
}

Translator for handling all your i18n needs.

func New

func New(box packr.Box, language string) (*Translator, error)

New Translator. Requires a packr.Box that points to the location of the translation files, as well as a default language. This will also call t.Load() and load the translations from disk.

func (*Translator) AddTranslation

func (t *Translator) AddTranslation(lang *language.Language, translations ...translation.Translation)

AddTranslation directly, without using a file. This is useful if you wish to load translations from a database, instead of disk.

func (*Translator) AvailableLanguages added in v0.11.0

func (t *Translator) AvailableLanguages() []string

AvailableLanguages gets the list of languages provided by the app

func (*Translator) Load

func (t *Translator) Load() error

Load translations from the t.Box.

func (*Translator) Middleware

func (t *Translator) Middleware() buffalo.MiddlewareFunc

Middleware for loading the translations for the language(s) selected. By default languages are loaded in the following order:

Cookie - "lang" Session - "lang" Header - "Accept-Language" Default - "en-US"

These values can be changed on the Translator itself. In development model the translation files will be reloaded on each request.

func (*Translator) Translate

func (t *Translator) Translate(c buffalo.Context, translationID string, args ...interface{}) string

Translate returns the translation of the string identified by translationID.

See https://github.com/nicksnyder/go-i18n

If there is no translation for translationID, then the translationID itself is returned. This makes it easy to identify missing translations in your app.

If translationID is a non-plural form, then the first variadic argument may be a map[string]interface{} or struct that contains template data.

If translationID is a plural form, the function accepts two parameter signatures 1. T(count int, data struct{}) The first variadic argument must be an integer type (int, int8, int16, int32, int64) or a float formatted as a string (e.g. "123.45"). The second variadic argument may be a map[string]interface{} or struct{} that contains template data. 2. T(data struct{}) data must be a struct{} or map[string]interface{} that contains a Count field and the template data, Count field must be an integer type (int, int8, int16, int32, int64) or a float formatted as a string (e.g. "123.45").
