Re: Pass the value from perl script to html page

Make a template file with distinctive tags to mark where data should be inserted. Load the file, replace the tags with variables. The following should explain what I mean, minus the loading of the template from a file.

use strict;
use warnings;

my ($text, %var);

$var{VAR1} = 'hawg';
$var{VAR2} = 'mansion';
$var{VAR3} = 'flagpole';

read(DATA, $text, 8192);
$text =~ s/<\?(\w+?)\?>/$var{$1}/g;
print $text;

__DATA__
Once upon a time there was a <?VAR1?> that lived in a
<?VAR2?> on top of a <?VAR3?>.

Note that VAR1, VAR2, VAR3, etc. can be any variable names you want.

I realize you're just trying to be helpful, but I can't help but think code handouts like this harm a programmer learning perl in the medium term. What is a new programmer more likely to do: Copy and paste this minimally functional templatting system that kinda works, or Do the ultimately more productive thing and learn how to install and use modules from CPAN. Most newer programmers will probably choose the first, lesser productive route (but you know what they say about assumptions). Just saying. A nudge to use something like HTML::Template with some sample code would probably be more helpful over the long term. Here's something I whipped up to demonstrate some of what HTML::Template can do.
