Hi,
This email I also sent to bug-bi...@gnu.org. But It's really a question, I
don't know Bison how to deal with it.
The following is my description.
Thanks,
Best regards,
Andy

Hi,
Flex/Bison is powerful. As a developer, I love them.
Now, I meet with a problem and can't find a good way to resolve it.
when Flex read "\n", I add my line number, then ignore it. Flex will read
another word, then return to bison as a token. Bison will start to reduce and
action my function. But in my function, I will use the line number which is
wrong obviously.
I have a way to resolve it. When Flex read "\n", I think it can return some
special character(key word) to make Bison to reduce the statement, then Bison
can ignore the special character.
I think Bison should support this way.
welcome to comment,
Thanks,
Best regards,
Andy
