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.

#!/usr/bin/perl use warnings; use strict; use HTML::Template; use CGI qw/:standard/; print header(); my $template=HTML::Template->new(filehandle=>*DATA,die_on_bad_params=> +1); my @count; foreach(1..10){ my %hash; $hash{NUMBER}=$_; push @count,\%hash; } $template->param( HEAD_TITLE=>'Test HTML::Template Page', PAGE_TITLE=>'This is a test HTML page.', CONTENT=>'Here is some sample content', COUNT=>\@count ); print $template->output; __DATA__ <html> <title><!-- TMPL_VAR HEAD_TITLE ESCAPE=HTML --></title> </html> <body> <h1><!-- TMPL_VAR PAGE_TITLE ESCAPE=HTML --></h1> <p><!-- TMPL_VAR CONTENT ESCAPE=HTML --></p> <p>I can count!</p> <ul> <!-- TMPL_LOOP COUNT --> <li><!-- TMPL_VAR NUMBER --></li> <!-- /TMPL_LOOP --> </ul> </body> </html>

indistinguishable from doubletalk.

[Corion]: Yay. Traditional finance situation averted. Bonds can be quoted in amounts (1_000_000 EUR) or per unit (1 unit). And a traditional error is to trade 2_000_000 piece when you meant to trade 2_000_000 EUR.
[Corion]: (one of my scripts simply catches high amounts and I phone people making that trade, ideally before the payment is due)
[Corion]: The sad thing is that my script sits at the end of the pipeline and can only look at the payments due today or tomorrow basically, while there are many more systems further up in the pipeline
