NAME

VERSION

SYNOPSIS

12           my $parser = DateTime::Format::Builder->create_parser(
13               regex  => qr/^(\d\d\d\d)(\d\d)(\d\d)T(\d\d)(\d\d)(\d\d)$/,
14               params => [qw( year month day hour minute second )],
15           );
16

SPECIFICATION

18       In addition to the common keys, "Regex" supports:
19
20       •   regex
21
22           regex is a regular expression that should capture elements of the
23           datetime string. This is a required element. This is the key whose
24           presence indicates it's a specification that belongs to this class.
25
26       •   params
27
28           params is an arrayref of key names. The captures from the regex are
29           mapped to these ($1 to the first element, $2 to the second, and so
30           on) and handed to "DateTime->new". This is a required element.
31
32       •   extra
33
34           extra is a hashref of extra arguments you wish to give to
35           "DateTime->new". For example, you could set the "year" or
36           "time_zone" to defaults:
37
38               extra => { year => 2004, time_zone => "Australia/Sydney" },
39
40       •   constructor is either an arrayref or a coderef. If an arrayref then
41           the first element is a class name or object, and the second element
42           is a method name (or coderef since Perl allows that sort of thing).
43           The arguments to the call are anything in $p and anything given in
44           the "extra" option above.
45
46           If only a coderef is supplied, then it is called with arguments of
47           $self, $p and "extra".
48
49           In short:
50
51               $self->$coderef( %{$p}, %{ $self->{extra} } );
52
53           The method is expected to return a valid DateTime object, or
54           "undef" in event of failure, but can conceivably return anything it
55           likes. So long as it's 'true'.
