[an error occurred while processing this directive] $NewMessage

  • $NewMessage is a global variable which, if set, is applied to the symbol name and tag of messages that are requested but have not yet been defined.
  • $NewMessage is applied to the symbol name, tag and language of a message if an explicit language is specified.
  • Mathematica looks for the value of name :: tag or name :: tag :: lang after $NewMessage has been applied.
  • You can set up $NewMessage to read the text of messages from files when they are first needed.
  • A typical value for $NewMessage might be Function[ToExpression[FindList[ files , ToString[MessageName[#1, #2]]]]].
  • See the Mathematica book: Section 2.8.21.
