[antlr-interest] Re: Get the line number in my deprecated messages

[pwolleba]

Thanks for your response Monty, it got me one step further!! :o)

As far I can see the getLine method is inside the CharScanner class, 
I can however not see any solution for reaching this class from my 
parser class. 

If there is someone, reading this newsgroup, that has implemented a 
deprecated message in their parsers I would be really happy if you 
could send me an example on how you did it. 
I have so far not found 1 single example that demonstrates this 
problem.

Best regards,
Per
