NAME

       DateTime::Format::Builder::Parser::Regex - Regex based date parsing

VERSION

       version 0.83

SYNOPSIS

           my $parser = DateTime::Format::Builder->create_parser(
               regex  => qr/^(\d\d\d\d)(\d\d)(\d\d)T(\d\d)(\d\d)(\d\d)$/,
               params => [qw( year month day hour minute second )],
           );

SPECIFICATION

       In addition to the common keys, "Regex" supports:

       •   regex

           regex is a regular expression that should capture elements of the datetime string.
           This is a required element. This is the key whose presence indicates it's a
           specification that belongs to this class.

       •   params

           params is an arrayref of key names. The captures from the regex are mapped to these
           ($1 to the first element, $2 to the second, and so on) and handed to "DateTime->new".
           This is a required element.

       •   extra

           extra is a hashref of extra arguments you wish to give to "DateTime->new". For
           example, you could set the "year" or "time_zone" to defaults:

               extra => { year => 2004, time_zone => "Australia/Sydney" },

       •   constructor is either an arrayref or a coderef. If an arrayref then the first element
           is a class name or object, and the second element is a method name (or coderef since
           Perl allows that sort of thing). The arguments to the call are anything in $p and
           anything given in the "extra" option above.

           If only a coderef is supplied, then it is called with arguments of $self, $p and
           "extra".

           In short:

               $self->$coderef( %{$p}, %{ $self->{extra} } );

           The method is expected to return a valid DateTime object, or "undef" in event of
           failure, but can conceivably return anything it likes. So long as it's 'true'.
