[antlr-interest] is this right

[Abhijit Nandkumar Ghonge]

Hi all,

Can we catch exceptions for the alternatives like this. If yes, then its
not working for me.



rule: a:A B C

| D E

exception // for alternate

catch [RecognitionException ex] {

reportError(ex.toString());

}

| F G

exception // for alternate

catch [RecognitionException ex] {

reportError(ex.toString());

}



;





This throws following error:



Error: Rule 'rule' already has an exception handler.



Regards,

Abhijit.
