Complement pattern match problem about dk.brics.automaton HOT 4 CLOSED

In this library I don't believe \d has any special meaning, so [0-9] should be used instead.
I think ~(201[0-8])[0-9]{4} is looking for the complement of an automaton that matches certain 8 digits strings that start with 201 i.e. any 4 digit string would ba match.

I think an expression that gives what you're describing is:
[0-9]{4}&~(201[0-8])

& is the intersection operator, and requires the patterns on both sides to match.
i.e. it must be 4 digits and must not be 201[0-8]

Thanks, Daniel. (Note that the complement operator ~ has higher precedence than concatenation.)

@RuralHunter, please see the javadoc, and please don't use GitHub issue tracking for general support questions about how to use the package.

Whoops you're right, the operator precedence means that ~(201[0-8])[0-9]{4} matches any string that's not 201[0-8], followed by any 4 digits.

ok, thanks guys.
@amoeller, got it. I have read the javadoc but still there are something confusing. I suggest add some examples for patterns supported by automaton in the doc/javadoc, especially those are different with normal regular expression.
