[antlr-interest] Synchronizing error messages from filter

[Monty Zukowski]

No, there is not a standard way to queue up that message.

You might make a custom token object that had a field for an error 
message.  Then override consume() in the parser to print your error 
before actually consuming the token passed it.

I'd need more details on how you want to handle that message to give 
you more specifics.
