NAME

6       DateTime::Format::Builder::Parser::Regex - Regex based date parsing
7

SYNOPSIS

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

SPECIFICATION

15       In addition to the common keys, "Regex" supports:
16
17       ·   regex is a regular expression that should capture elements of the
18           datetime string.  This is a required element. This is the key whose
19           presence indicates it's a specification that belongs to this class.
20
21       ·   params is an arrayref of key names. The captures from the regex are
22           mapped to these ($1 to the first element, $2 to the second, and so
23           on) and handed to "DateTime->new()".  This is a required element.
24
25       ·   extra is a hashref of extra arguments you wish to give to
26           "DateTime->new()". For example, you could set the "year" or
27           "time_zone" to defaults:
28
29               extra => { year => 2004, time_zone => "Australia/Sydney" },
30
31       ·   constructor is either an arrayref or a coderef. If an arrayref then
32           the first element is a class name or object, and the second element
33           is a method name (or coderef since Perl allows that sort of thing).
34           The arguments to the call are anything in $p and anything given in
35           the "extra" option above.
36
37           If only a coderef is supplied, then it is called with arguments of
38           $self, $p and "extra".
39
40           In short:
41
42                       $self->$coderef( %$p, %{ $self->{extra} } );
43
44           The method is expected to return a valid DateTime object, or undef
45           in event of failure, but can conceivably return anything it likes.
46           So long as it's 'true'.
