NAME
vars::i - Perl pragma to declare and simultaneously initialize global variables.
SYNOPSIS
use Data::Dumper;
$Data::Dumper::Deparse = 1;
#
use vars::i '$VERSION' => 3.44;
use vars::i '@BORG' => 6 .. 6;
use vars::i '%BORD' => 1 .. 10;
use vars::i '&VERSION' => sub(){rand 20};
use vars::i '*SOUTH' => *STDOUT;
#
BEGIN {
print SOUTH Dumper [
$VERSION, \@BORG, \%BORD, \&VERSION
];
}
#
use vars::i [ # has the same affect as the 5 use statements above
'$VERSION' => 3.66,
'@BORG' => [6 .. 6],
'%BORD' => {1 .. 10},
'&VERSION' => sub(){rand 20},
'*SOUTH' => *STDOUT,
];
#
print SOUTH Dumper [ $VERSION, \@BORG, \%BORD, \&VERSION ];
#
__END__
DESCRIPTION
For whatever reason, I once had to write something like
BEGIN {
use vars '$VERSION';
$VERSION = 3;
}
and I really didn't like typing that much.
Also, I like being able to say
use vars::i '$VERSION' => sprintf("%d.%02d", q$Revision: 1.3 $ =~ /: (\d+)\.(\d+)/);
use vars::i [
'$VERSION' => sprintf("%d.%02d", q$Revision: 1.3 $ =~ /: (\d+)\.(\d+)/),
'$REVISION'=> '$Id: GENERIC.pm,v 1.3 2002/06/02 11:12:38 _ Exp $',
];
Like with use vars;
, there is no need to fully qualify the variable name.
