Hi All.
I thought I would get my feet wet by writing a parser for Objective-C
type encodings. I thought it would be pretty easy for such a brief
"language", but it is turning out to be pretty difficult.
One of the problems lies in parsing something like this:
{vids=^vids}
which means a struct named "vids", which is composed of void * (^v),
int, double, and short.
After the "{", I need to interpret vids as a single token, and after
the "=", I need to interpret the characters as separate tokens.
One of the interesting things I found was that this is legal:
NUMBER : '0'..'9';
but this is not:
number : '0'..'9';
I bumped into this because I thought I'd "inline" the rule for the
name after the "{". Can someone explain this?
Is there a way I can say, "use tokenizer rule A after the "{", but use
tokenizer rule B after the "=".
AntlrWorks has been great for learning by playing. Thanks for any help!
