Hello,
right now I trying to attack my comment problem with a predicate:
COMMENT
:
"--"
(
~('-'|'\n'|'\r'|'\u000b'|'\u000c') | {LA(2) != '-'}? '-'
)*
{
// consume "end-of-comment" characters
switch(LA(1)) {
..
case '\u000b' : { <== syntax error on '\u000b'
match('\u000b'); <== dito
break;
}
..
}
}
;
Please don't question the rule as such (pending: try posted
proposals).
The problem is rather that ANTLR complains about '\u000b' albeit it
appears to me that this is pretty much correct Java.
Smells like a bug?
Cheers,
Wolfgang.
