glass-easel-i18n

glass-easel 非侵入式国际化支持

使用指南

快速开始

添加同名 locale 目录,例如 pages/index 下新增 index.locale ,添加翻译文件 en-us.po(文件名即为 locale

  - src/pages
    - index
      - index.locale //新增
        - zh-hk.po
        - en-us.po
        - ja.po
        - .....
      - index.wxml
      - index.ts
      - index.wxss
      - index.json

index.wxml中使用 <!I18N> 声明启用 i18n

<!I18N>  <!-- 启用 i18n 的声明 -->
<view>一些文本</view>

配置翻译文件 index.locale/en-us.po

msgid "一些文字"
msgstr "Some words"

index.ts 中增加 locale

Page({
  data: {
    locale: 'en-us',
  },
  // 可配置 methods 去更改 locale
  changeLocale() {}
})

webpack.config.js 中新增 GlassEaselMiniprogramWxmlI18nLoader

pnpm install --save-dev glass-easel-miniprogram-i18n-webpack-loader
rules: [
  {
    // wxml should be explicit handled with a loader
    test: /\.wxml$/,
    use: [
      GlassEaselMiniprogramWxmlLoader,
      // configPath is exposed to loader
      {
        loader: GlassEaselMiniprogramWxmlI18nLoader,  // 新增
        options: {
          configPath: __dirname,
        },
      },
    ],
    exclude: /node_modules/,
  },
]

原理说明

通过翻译词条配置将原先的模板预编译成支持 i18n ,例如:

<!I18N>  <!-- 启用 i18n 的声明 -->
<view>一些文本</view>

经过 i18n 预编译器后,可以得到:

<block wx:if="{{ locale === "en-us" }}">
  <view>Some words</view>
</block>
<block wx:else>
  <view>一些文本</view>
</block>

进阶用法

可参考 glass-easel-i18n/glass-easel-miniprogram-i18n-template

属性翻译

属性翻译需要在配置文件中添加属性白名单

<div class="item" title="说明" exclued-attribute="说明">含属性的节点</div>

翻译文件:

msgid "含属性的节点"
msgstr "Node with attributes"

msgid "说明"
msgstr "explanation"

数据绑定

需要翻译的文本块中有数据绑定,这种情况下需要用到占位符:

<view>{{ a }} 加 {{ b }} 得到 {{ a+b }}</view>

翻译文件如下,注意占位符需要大写且按字母序列依次递增

msgid "{{A}} 加 {{B}} 得到 {{C}}"
msgstr "Add {{A}} to {{B}} to get {{C}}"

整体翻译

一系列子节点需要被当做一个整体来翻译,在模板中添加声明 <!I18N translate-children>

<div>
  <!I18N translate-children><span style="color: red"></span></div>

翻译文件:

msgid "我{{A}}你"
msgstr "I {{A}} You"

msgid "爱"
msgstr "Love"

或者整体翻译:

msgid "我{{A}}你"
msgstr "愛してます"

全局翻译

src/locale 目录中配置全局翻译,文件名即为 locale

可以不配置当前 page 的翻译文件,默认会先寻找全局翻译,且全局翻译优先级较低

src/locale/en-us.po:

msgid "一些文字"
msgstr "Some words"

src/pages/index/index.locale/en-us.po:

msgid "一些文字"
msgstr "[Global] Some words"

msgid "全局的翻译"
msgstr "Global translation"

模板引用

如果使用模板引用语法,需要在模板中传入 locale

<template name="shared-template-slice">
  <div class="item"> {{ a }} + {{ b }} = {{ a+b }} </div>
  <div class="item">template里的一些文字</div>
</template>
<template is="shared-template-slice" data="{{ a: 3, b: 4, locale}}"></template>

配置文件

项目根目录下新增 i18nconfig.json,写入需要被翻译的属性名:

{
  "attributes": ["title"]
}

收集待翻译词条

命令行配置

package.json 中新增脚本

  "scripts": {
    "search":"glass-easel-i18n search"
  },

命令行参数

【必选】使用-f 或者 --file 制定需要收集的文件路径

【可选】使用 -p 或者 --placeholder 来指定输出文件中 msgstr 的值,默认为 “尚未翻译”

pnpm run search -f ./src/pages/index/index.wxml
pnpm run search -f ./src/pages/index/index.wxml -p "未翻译"

如果使用 npm 作为包管理工具需要添加 --

npm run search -- -f ./src/pages/index/index.wxml
npm run search -- -f ./src/pages/index/index.wxml -p "未翻译"

-f 指定的 wxml 文件的同级目录下会输出 untranslated.po
