MessageList

MessageList[n]

is a global object assigned to be a list of the names of messages generated during the processing of the n^(th) input line.

Details

  • Only messages that are actually output are included in the list MessageList[n].
  • The message names in the list are wrapped with HoldForm.
  • MessageList[n] includes messages generated both by built‐in functions and by explicit invocations of Message.

Examples

Basic Examples  (1)

Get any messages that were generated by the previous output:

Wolfram Language code: LinearSolve[{{0}}, {1}]
Wolfram Language code: MessageList[-1]

There were no messages produced in the previous command:

Wolfram Language code: MessageList[-1]

Now the command that gave the message is the third previous command:

Wolfram Language code: MessageList[-3]

Get a list of all the messages that were generated in a session:

Wolfram Language code: Map[MessageList, Range[$Line - 1]]
