NAME

Path::Dispatcher::Rule::Tokens - predicate is a list of tokens

CONTENTS

SYNOPSIS



    my $rule = Path::Dispatcher::Rule::Tokens->new(
        tokens    => [ "comment", "show", qr/^\d+$/ ],
        delimiter => /,
        block     => sub { display_comment(shift->pos(3)) },
    );

    $rule->match("/comment/show/25");



DESCRIPTION

Rules of this class use a list of tokens to match the path.

ATTRIBUTES

    tokens

Each token can be a literal string, a regular expression, or a list of either (which are taken to mean alternations). For example, the tokens:



    [ ticket, [ show, display ], [ qr/^\d+$/, qr/^#\w{3}/ ] ]



first matches ticket. Then, the next token must be show or display. The final token must be a number or a pound sign followed by three word characters.

The results are the tokens in the original string, as they were matched. If you have three tokens, then match->pos(1) will be the string’s first token (ticket), match->pos(2) its second (display), and match->pos(3) its third (#AAA).

Capture groups inside a regex token are completely ignored.

    delimiter

A string that is used to tokenize the path. The delimiter must be a string because prefix matches use join on unmatched tokens to return the leftover path. In the future this may be extended to support having a regex delimiter.

The default is a space, but if you’re matching URLs you probably want to change this to a slash.

    case_sensitive

Decide whether the rule matching is case sensitive. Default is 1, case sensitive matching.
