Path::Dispatcher::Rule::Tokens - predicate is a list of tokens
version 1.08
my $rule = Path::Dispatcher::Rule::Tokens->new(
tokens => [ "comment", "show", qr/^\d+$/ ],
delimiter => '/',
block => sub { display_comment(shift->pos(3)) },
);
$rule->match("/comment/show/25");
Rules of this class use a list of tokens to match the path.
Each token can be a literal string, a regular expression, or a list of either (which are taken to mean alternations). For example, the tokens:
[ 'ticket', [ 'show', 'display' ], [ qr/^\d+$/, 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.
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.
Decide whether the rule matching is case sensitive. Default is 1, case sensitive matching.
