Re: Regex Substitution in sub

[Aristotle]

Just wanted to note that you shouldn't use /o. it does nothing in the examples you showed, so I suspect you don't know what exactly its effects are; in that case it can get you in big trouble. If you are using it because you read that it is about efficiency, read up about the qr// "operator" whose introduction in Perl 5.005 (almost) obsoleted /o.

I read today in everyone's favourite module:

         $toencode =~ s{&}{&}gso;
         $toencode =~ s{<}{&lt;}gso;
         $toencode =~ s{>}{&gt;}gso;
         $toencode =~ s{"}{&quot;}gso;
         my $latin = uc $self->{'.charset'} eq 'ISO-8859-1' ||
                     uc $self->{'.charset'} eq 'WINDOWS-1252';
         if ($latin) {  # bug in some browsers
                $toencode =~ s{'}{&#39;}gso;
                $toencode =~ s{\x8b}{&#8249;}gso;
                $toencode =~ s{\x9b}{&#8250;}gso;
                if (defined $newlinestoo && $newlinestoo) {
                     $toencode =~ s{\012}{&#10;}gso;
                     $toencode =~ s{\015}{&#13;}gso;
                }
         }
         return $toencode;

This is the heavy strictless module that everyone still recommends. /o? /s? WHY?!

Can we please stop using and recommending CGI.pm now? Please?

Quoting myself from Re^3: Handy dandy CPAN pollution:

I've poured over CGI myself. Basically, that module is a horrible mess. That's ok for someone who wants to use it, as it's not only one of the few messes that work, but one of the even fewer than work well in practice.

I don't really like the module, but we need a good replacement. I was switching to CGI::Simple for a while (as I wrote there), but have now actually found CGI's HTML generation useful in combination with Template Toolkit, so I'm reluctantly back to it. We need a full replacement for all of the functionality of that mess before we can stop recommending it.. :-/

CGI stuff (Form parsing, header sending, uploads, etc...)

CGI::Simple

Tag generation

HTML::EasyTags

Am I forgetting something?
