I18n

Management and use of multilingual data using INI files.

中文说明

Features

• Easy to use, supports loading multiple languages, multiple files
• Two data loading modes: single file FileMode(default), folder DirMode
• Support to set the default language and fallback language
  • when the default language data is not found, it will automatically try to find the fallback language
• Support parameter replacement, there are two modes
  • SprintfMode replaces parameters via fmt.Sprintf
  • ReplaceMode uses func strings.Replacer

Install

go get github.com/gookit/i18n

Godoc

• go doc

Usage

Structs on use single FileMode mode:

lang/
    en.ini
    ru.ini
    zh-CN.ini
    zh-TW.ini
    ... ...

Structs on use folder DirMode mode:

lang/
    en/
        default.ini
        ... ...
    zh-CN/
        default.ini
        ... ...
    zh-TW/
        default.ini
        ... ...

Init i18n

import "github/gookit/i18n"

languages := map[string]string{
    "en": "English",
    "zh-CN": "简体中文",
    // "zh-TW": "繁体中文",
}

// The default instance initialized directly here
i18n.Init("conf/lang", "en", languages)

// Create a custom new instance
// i18n.New(langDir string, defLang string, languages)
// i18n.NewEmpty()

Translate message

// Translate from default language
msg = i18n.Dt("key")
// with arguments. 
msg = i18n.DefTr("key1", "arg1", "arg2")

// Translate from the specified language
msg := i18n.Tr("en", "key")

Function list:

// Translate from default language
func Dt(key string, args ...interface{}) string
func Dtr(key string, args ...interface{}) string
func DefTr(key string, args ...interface{}) string

// Translate from the specified language
func T(lang, key string, args ...interface{}) string
func Tr(lang, key string, args ...interface{}) string

Parameters replacement mode

Use sprintf mode

TIP: default mode is SprintfMode

# en.ini
desc = I am %s, age is %d

Usage with parameters like sprintf:

msg := i18n.Tr("en", "desc", "tom", 22)
// Output: "I am tom, age is 22"

Use replace mode

Enable replace mode:

// set mode
i18n.Std().TransMode = i18n.ReplaceMode

// OR
i18n.Config(func(l *i18n.I18n) {
    l.TransMode = i18n.ReplaceMode
})

Examples for language data:

# en.ini
desc = I am {name}, age is {age}

Usage with parameters:

// args is {"name": "tom", "age": 22}
msg := i18n.Tr("en", "desc", "name", "tom", "age", 22)
// Output: "I am tom, age is 22"

Usage with kv-map parameters:

msg := i18n.Tr("en", "desc", map[string]interface{}{
    "name": "tom",
    "age": 22,
})
// Output: "I am tom, age is 22"
