=head1 NAME

Path::Dispatcher::Rule::Regex - predicate is a regular expression

=head1 VERSION

version 1.08


    my $rule = Path::Dispatcher::Rule::Regex->new(
        regex => qr{^/comment(s?)/(\d+)$},
        block => sub { display_comment(shift->pos(2)) },


Rules of this class use a regular expression to match against the path.


=head2 regex

The regular expression to match against the path. It works just as you'd expect!

The capture variables (C<$1>, C<$2>, etc) will be available in the match
object as C<< ->pos(1) >> etc. C<$`>, C<$&>, and C<$'> are not restored.

=head1 SUPPORT

Bugs may be submitted through L<the RT bug tracker|>
(or L<|>).
