Angular 2+本地化(i18n)RTL支持 [英] Angular 2+ localization (i18n) rtl support
问题描述
在本地化的Angular 2+应用程序中添加从右到左(rtl)支持的最佳做法是什么(例如希伯来语和阿拉伯语)?我浏览了一些教程，包括国际化(i18n)，但似乎没有一个涵盖这方面.我希望例如在应用程序的构建步骤中将html direction属性(例如<html dir="rtl">)与在18n属性中定义的翻译一起添加.
What is the best practice for adding right to left (rtl) support into a localized Angular 2+ app (e.g. for Hebrew and Arabic languages)? I looked through several tutorials including Internationalization (i18n) but none seem to be covering that. I would expect, for example, the html direction property (e.g. <html dir="rtl">) to be added along with translations defined in 18n attributes at the build step of the app.
推荐答案
可以将i18n-dir添加为 .因此，到目前为止，我发现的最佳方法是将i18n-dir dir="ltr"(其中ltr是默认方向)添加到根组件模板(例如app.component.html)的根元素中，如下所示:
It is possible to add i18n-dir as described in the docs. So, the best approach I found so far is to add i18n-dir dir="ltr" (where ltr is a default direction) to the root element in the the root component template (e.g. app.component.html) like so:
<div i18n-dir dir="ltr">
<!-- The rest of the content -->
</div>
一旦生成翻译文件，对应的trans-unit就会出现在每个文件中，其中source包含默认方向，在这种情况下为ltr.因此，您只需要将相应语言的单位target设置为rtl.
Once you generate translation files a corresponding trans-unit will appear in each of them with source containing default direction, which is ltr in this case. So, you just need to set the target of the unit to rtl for corresponding languages.
