## Internationalization

The cube-ui component uses Chinese internally by default. If you want to use another language, you need to set it in multiple languages. Take English as an example in main.js:

```js

  // Full import
  import Vue from 'vue'
  import CubeUI from 'cube-ui'
  import enUSMessages from 'cube-ui/src/locale/lang/en-US' // Built-in in cube-ui
  import jaJPMessages from '../some/path/lang/ja-JP' // Import Japanese language by yourself
  const Locale = CubeUI.Locale
  Vue.use(CubeUI)
  Locale.use('en-US', enUSMessages)
  Locale.use('ja-JP', jaJPMessages)

```

Or, import by module

```js

  // Only import ActionSheet
  import Vue from 'vue'
  import { ActionSheet, Locale } from 'cube-ui'
  import enUSMessages from 'cube-ui/src/locale/lang/en-US'

  Vue.use(Locale)
  Locale.use('en-US', enUSMessages)

```

Cube-ui will watch the current language type, so it automatically renders once language type has changed, and caches the loaded translation. When the language type is switched and the language translation is already installed, cube-ui directly takes the cached copy. Similar pseudo code is as follows:

```js

  // Only import ActionSheet
  import Vue from 'vue'
  import { ActionSheet, Locale } from 'cube-ui'
  import enUSMessages from 'cube-ui/src/locale/lang/en-US'

  // Chinese translation by default
  Vue.use(Locale)

  // Click to switch English language translation
  one.click(() =>{
    Locale.use('en-US', enUSMessages)
  })

  // Switch back to default
  another.click(() => {
    // Take the translation from the cache
    Locale.use('zh-CN')
  })

```

The default messages is as follows

```js

  export default {
    cancel: '取消',
    confirm: '确认',
    ok: '确定',
    prev: '上一步',
    next: '下一步',
    selectText: '请选择',
    now: '现在',
    selectTime: '选择时间',
    today: '今日',
    formatDate: 'M月D日',
    hours: '点',
    minutes: '分',
    validator: {
      required: '此为必填项',
      type: {
        string: '请输入字符',
        number: '请输入数字',
        array: '数据类型应为数组',
        date: '请选择有效日期',
        email: '请输入有效邮箱',
        tel: '请输入有效的手机号码',
        url: '请输入有效网址'
      },
      min: {
        string: '至少输入 {{config}} 位字符',
        number: '不得小于 {{config}}',
        array: '请选择至少 {{config}} 项',
        date: '请选择 {{config | toLocaleDateString("yyyy年MM月dd日")}} 之后的时间',
        email: '至少输入 {{config}} 位字符',
        tel: '至少输入 {{config}} 位字符',
        url: '至少输入 {{config}} 位字符'
      },
      max: {
        string: '请勿超过 {{config}} 位字符',
        number: '请勿大于 {{config}}',
        array: '最多选择 {{config}} 项',
        date: '请选择 {{config | toLocaleDateString("yyyy年MM月dd日")}} 之前的时间',
        email: '请勿超过 {{config}} 位字符',
        tel: '请勿超过 {{config}} 位字符',
        url: '请勿超过 {{config}} 位字符'
      },
      len: {
        string: '请输入 {{config}} 位字符',
        number: '长度应等于 {{config}}',
        array: '请选择 {{config}} 项',
        date: '请选择 {{config | toLocaleDateString("yyyy年MM月dd日")}} 之前的时间',
        email: '请输入 {{config}} 位字符',
        tel: '请输入 {{config}} 位字符',
        url: '请输入 {{config}} 位字符'
      },
      pattern: '格式错误',
      custom: '未通过校验',
      notWhitespace: '空白内容无效'
    }
  }

```
