This is a good time to make a module to use from each script. As an example consider these two files...
testPage.pl
#!/usr/local/bin/perl
use strict;
use Page;
print &Header ('test of Page.pm'), "Some content would be here", &Footer ();
#!/usr/local/bin/perl
package Page;
use strict;
BEGIN{
use Exporter ();
use vars qw ($VERSION @ISA @EXPORT);
$VERSION = 0.10;
@ISA = qw (Exporter);
@EXPORT = qw (&Header &Footer);
}
################################################ subroutine header begin ##
################################################## subroutine header end ##
sub Header
{
my ($title) = @_;
$title = qq(<title>$title</title>) if ($title);
#///////////////////////////message
my $string = <<EOF;
Content-type: text/html
<html>
<head>
$title
</head>
<body marginheight="0" marginwidth="0" topmargin="0"
leftmargin="0" rightmargin="0" bottommargin="0">
EOF
#///////////////////////////message
return ($string);
}
################################################ subroutine header begin ##
################################################## subroutine header end ##
sub Footer
{
#///////////////////////////message
my $string = <<EOF;
<hr>
<center>Copyright © 2001 by me</center>
</body></html>
EOF
#///////////////////////////message
return ($string);
}
###########################################################################
###########################################################################
1; #this line is important, without it your module may not work correctly
on the command line or at a DOS prompt. The last section of stuff you get will be the contents of the @INC.
And now for a bit of shameless advertising. I will be presenting a talk on "Making a Module" at YAPC::America::North in Montreal next week. After the talk I will return to this thread and include a link to the slides, but I don't want to spoil the surprise by making them public yet. The original title was "Making a Module: And All the Crap that CPAN Wants Too", but I have to send my slides through the lawyers at work so I have simplified the title.
