[antlr-interest] Architectural Suggestion: Pluggable Error Reporting

[Marc-André Laverdière]

Hello,

In the Java implementation, I'm seeing BaseRecognizer.emitErrorMessage, 
that prints to stderr by default. I was thinking of this, and the 
related functions, and saw that I could recommend something.

Maybe the error reporting logic could be delegated to an overridable 
BaseErrorDisplayer class. The BaseRecognizer would have a set/get pair 
to deal with it. It would not have much performance overhead and would 
give us some customization for people like me who would like to report 
directly to a GUI.

What do you think of this idea?

Regards,
