Adjust the order of parameters during translation

[Wenjie Wu]

Take this block as an example: item _ of _

In Chinese, the order of parameters needs to be adjusted. I guess there are some other languages with similar requirement.

In Scratch 3.0, a parameter can be referenced in the translated text by its id (https://github.com/scratchfoundation/scratch-l10n/blob/master/editor/extensions/zh-cn.json#L17). How to do it at MicroBlocks?

We may eventually add support parameter reordering -- as we eventually did in Scratch -- but it's not a simple, localized change, so I'm afraid it won't happen in the near term. Meanwhile, translators will need to figure out wordings that make sense but preserve the parameter order.

translators will need to figure out wordings that make sense but preserve the parameter order.

Maybe we can use the backreference style of regular expressions: https://www.regular-expressions.info/backref.html

eg:

en: item _ of _
zh_cn:  _2 的第 _1 项

MicroBlocks already has a large number of translation files, compatibility is necessary for this. For translated paragraphs without backreference symbols, the default order is maintained.
