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'.
