DateTime::Format::Builder::Parser::Regex(3)

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

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 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 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 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'.

SUPPORT
Support for this module is provided via the datetime@perl.org email list. See http://lists.perl.org/ for more details.

Alternatively, log them via the CPAN RT system via the web or email:

    bug-datetime-format-builder@rt.cpan.org

This makes it much easier for me to track things and thus means your problem is less likely to be neglected.
