I18n 生命周期

插件用这些生命周期来加载国际化 (i18n) 相关的数据。

getTranslationFiles({content})

插件需要声明它们想要使用的 JSON 翻译文件。

Returns translation files {path: string, content: ChromeI18nJSON}:

• path: relative to the plugin localized folder i18n/[locale]/[pluginName]. Extension .json should be omitted to remain generic.
• content: using the Chrome i18n JSON format.

These files will be written by the write-translations CLI to the plugin i18n subfolder, and will be read in the appropriate locale before calling translateContent() and translateThemeConfig()

示例：

my-plugin.js

export default function (context, options) {
  return {
    name: 'my-plugin',
    async getTranslationFiles({content}) {
      return [
        {
          path: 'sidebar-labels',
          content: {
            someSidebarLabel: {
              message: 'Some Sidebar Label',
              description: 'A label used in my plugin in the sidebar',
            },
            someLabelFromContent: content.myLabel,
          },
        },
      ];
    },
  };
}

translateContent({content,translationFiles})

使用本地化完毕的翻译文件翻译插件内容。

返回本地化的插件内容。

The contentLoaded() lifecycle will be called with the localized plugin content returned by translateContent().

示例：

my-plugin.js

export default function (context, options) {
  return {
    name: 'my-plugin',
    translateContent({content, translationFiles}) {
      const myTranslationFile = translationFiles.find(
        (f) => f.path === 'myTranslationFile',
      );
      return {
        ...content,
        someContentLabel: myTranslationFile.someContentLabel.message,
      };
    },
  };
}

translateThemeConfig({themeConfig,translationFiles})

Translate the site themeConfig labels, using the localized translation files.

Returns the localized themeConfig.

示例：

my-plugin.js

export default function (context, options) {
  return {
    name: 'my-theme',
    translateThemeConfig({themeConfig, translationFiles}) {
      const myTranslationFile = translationFiles.find(
        (f) => f.path === 'myTranslationFile',
      );
      return {
        ...themeConfig,
        someThemeConfigLabel: myTranslationFile.someThemeConfigLabel.message,
      };
    },
  };
}

async getDefaultCodeTranslationMessages()

Themes using the <Translate> API can provide default code translation messages.

It should return messages in Record<string, string>, where keys are translation IDs and values are messages (without the description) localized using the site's current locale.

示例：

my-plugin.js

export default function (context, options) {
  return {
    name: 'my-theme',
    async getDefaultCodeTranslationMessages() {
      return readJsonFile(`${context.i18n.currentLocale}.json`);
    },
  };
}
