DateTime::Format::Builder::Parser::Regex - Regex based date parsing
version 0.83
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
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 C<year> or C<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'.
