DateTime::Format::Builder::Parser::Regex

version 0.81

   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 ) ],
   );

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'.
