Hi -
I am trying to print the filename, line number, and the actual line that
has an error. Getting the filename and line number is relatively easy,
however I have not found a good way to get the actual line that caused
the error. The original implementation of displayRecognitionError(..)
does not print the line. TIA
Here is what I have:
.g file
----------
@parser::apifuncs
{
RECOGNIZER->displayRecognitionError = AntlrErrorHandler;
}
.c file
----------
void AntlrErrorHandler (pANTLR3_BASE_RECOGNIZER recognizer,
pANTLR3_UINT8 * tokenNames)
{
ANTLR3_FPRINTF(stderr, "File: %s\r\n",
recognizer->state->exception->streamName->chars);
ANTLR3_FPRINTF(stderr, "Line number: %s\r\n",
recognizer->state->exception->line);
// how do I get the actual line?
// ...
}
