you'd just need multiple multi-line rules that look something like this (not sure if there is an escape char):
new MultiLineRule("q(", ")\n", token, (char) 0, true);
new MultiLineRule("q{", "}\n", token, (char) 0, true);
no?
Actually, there's another bug here, and it's a tricky one, so heads up in case you might run to into in similar code on own work: If you use different rules to match the same token, the partitioner can at some times (especially for multi-line rules) try to resume scanning (look only for the end of the partition starting from the middle of it) using a rule different from the one that started the partition. So code like this:
q(
blah
}
might be scanned correctly as a partition of that token type, because one rule would start it, but another rule might end the scanning successfully. I mentioned this in more detail in this Eclipse bug:
