Hello all,
I have a need to have an exception to my comment rule that I want to know the
best way to handle. Basically, I need to not treat something that starts with,
say, #ABCD as not a comment. (This is for backward compatibility.)
For example:
# This is a comment
Something = value;
#ABCD This = that
This needs to treat the third line as if the #ABCD didn't exist. So I'm trying
something like this:
fragment NONCOMMENT : '#ABCD' ;
COMMENT
: NONCOMMENT { $channel=HIDDEN; }
| '#' ~('\r' | '\n')* { $channel=HIDDEN; };
This seems to work fine, but when I check the grammar, I get a warning that
#ABCD can match multiple alternatives and so the second alternative is
disabled. This is the desired behavior, of course, but since it gives me a
warning, I wonder if there a better way to switch off treating this thing that
looks like a comment as a comment.
Thanks,
-JEEP
