DateTime::Format::Builder::Parser::Regex(3pm) User Contributed Perl Documentation DateTime::Format::Builder::Parser::Regex(3pm)
NAME
DateTime::Format::Builder::Parser::Regex - Regex based date parsing
SYNOPSIS
my $parser = DateTime::Format::Builder->create_parser(
regex => qr/^(dddd)(dd)(dd)T(dd)(dd)(dd)$/,
params => [ qw( year month day hour minute second ) ],
);
SPECIFICATION
In addition to the common keys, "Regex" supports:
o 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.
o 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.
o 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" },
o 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'.
