NAME

Path::Dispatcher::Rule::CodeRef - predicate is any subroutine

CONTENTS

SYNOPSIS



    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!"



DESCRIPTION

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.

ATTRIBUTES

    matcher

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 $_.
