I would like to use hugo new to create content because it could generate date in the format I want. However, I don’t really know how to set language for the generated post as I wish. See image below:
The languages format of my site is in dir structure, which is content/language-code/section/post.md. Is there a way to archive this?
It does not appear that Hugo is able to do that. You will need to run the command once per language. If thought over properly this might be a great feature request for the hugo new command.
I answered that issue before I read your reply… a good place to add some thoughts about the way hugo new works in general, not only translations I think.
