Perl module to get warn or die to render as HTML

jira0004 has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

Here is the thing, I am working on a Perl CGI that some one else wrote. The thing that I want is a Perl module, either in the standard distribution, or from CPAN that causes a die or a warn to render as nice HTML in a web-browser for debugging purposes.

I realize I could put the CGI code in an eval block, catch the exception generated by die and then create the HTML myself, but I was wondering if there was any nice Perl module that happened to do such a thing for me. Does any one have any ideas about such a Perl module?

Thanks

Take a look at the standard CGI::Carp module and its fatalsToBrowser / warningsToBrowser options. "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

And don't forget to configure things so it is turned on in development and off in production. Else you'll provide an ideal tool to help attackers debug their attacks against any flaws that they find in your site.	[reply]

Great point. At my org we have a web server error log and the number of scripts that 'use warnings' that are in production is outrageous. So also turn off warnings and debugging in general in production so that other web programmers don't have to sift through 100+ lines of Net::FTP debug output to find the line in the error log from their own script.

causes a die or a warn to render as nice HTML in a web-browser for debugging purposes Check this out: `#!/usr/bin/perl -w use strict; use CGI qw/ :all /; $SIG{__DIE__} = \&htmldie; open FIN,"< some_stupid_nonexistant_file.or.other" or die $!; my $line=<FIN>; exit(0); sub htmldie { my @args=@_; print header,start_html,pre(join("\n",@args)),end_html; exit(0); }` [download] I found this by doing a quick check of perldoc -f die which shows this pattern.
