Hello,
I’m trying to parse a C expression from an input stream. I’d like the
parser to stop as soon as a valid expression is read (or an error is
encountered).
However, the default behavior is to stop whenever a valid expression
/followed by the end-of-file marker/ is encountered. Thus, if the input
stream contains a sequence of 2 or more expressions, the parser will
report an error because it’s expecting $end after the first expression.
Any idea how to achieve what I want?
Thanks,
Ludo’.
