Re^2: How to Debug the CGI Codes

[strat]

For development, I even use:

use CGI::Carp qw/fatalsToBrowser warningsToBrowser/;

because it also handles warnings

Update: is wrong, see the posting from reneeb below

[reneeb]

To handle warnings, you have to call the warningsToBrowser subroutine with a true argument. See documentation of CGI::Carp.

Just a note:
warningsToBrowser(1) must be explicitly called after printing the page header, and will output all warnings as HTML comments. It's its difference from fatalsToBrowser, which catches all fatal errors (even compile-time!) without any additional actions. The CGI::Carp documentation contains additional info.

UPD: i haven't seen the previous reply while writing this :)
