Path::Dispatcher::Rule::CodeRef - predicate is any subroutine
version 1.08
my $rule = Path::Dispatcher::Rule::CodeRef->new(
matcher => sub { time % 2 },
block => sub { warn "Odd time!" },
);
my $undef = $rule->match("foo"); # even time; no match :)
my $match = $rule->match("foo"); # odd time; creates a Path::Dispatcher::Match
$rule->run; # warns "Odd time!"
Rules of this class can match arbitrarily complex values. This should be used only when there is no other recourse, because there's no way we can inspect how things match.
You're much better off creating a custom subclass of Path::Dispatcher::Rule if at all possible.
A coderef that returns "undef" if there's no match, otherwise a list of strings (the results).
The coderef receives the path object as its argument, and the path string as $_.
