View Source (macro)

Creates a parser ~idn-hostname/1.

This function returns {:ok} if the passed string is a valid idn hostname, or {:error, reason} if it is not.

The function will only be created once per module, and it is safe to call the macro more than once.



this function generates code that requires the :idna library.



  • :name (atom): the name of the function to create. Defaults to :"~idn-hostname"
