CGI::Carp compilation errors

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

I'm fairly new to Perl and particularly new to it for CGI
I want to get the basic right for seeing debug output to my browser
so far I have


#!/usr/bin/perl -wT

BEGIN {
    $|=1;
    print "Content-type: text/html\n\n";
    use CGI::Carp('fatalsToBrowser');

}

use strict;
use CGI;

$var = 'hello world';
print $var;
[download]

This doesn't give me the compilation errors that it should(?).
Is there anything else I can add to make this more verbose.
I want to be able to see all the compilation warnings that use strict offers me

thanks in advance of any help

Cyril

There were several versions of CGI::Carp that failed to catch compile-time errors. Upgrade or downgrade. - tye	[reply]

if you like it more verbose try: `use CGI::Carp qw(fatalsToBrowser warningsToBrowser);` [download] and take a closer look to the Tutorials Section - CGI	[reply] [d/l]

I still get Global symbol "$var" requires explicit package name at /usr/local/apache/htdocs/cgi-bin/debug.cgi line 13. Global symbol "$var" requires explicit package name at /usr/local/apache/htdocs/cgi-bin/debug.cgi line 14. Execution of /usr/local/apache/htdocs/cgi-bin/debug.cgi aborted due to compilation errors. appearing in my apache error log rather than my browser my question is more out of curiosity than necessity.

If I run your script from the commandline I get: `Content-type: text/html <h1>Software error:</h1> <pre>Global symbol "$var" requires explicit package name at +/home/emile/tmp/aap.pl line 13. Global symbol "$var" requires explicit package name at /home +/emile/tmp/aap.pl line 14. Execution of /home/emile/tmp/aap.pl aborted due to compilation errors. </pre> <p> For help, please send mail to this site's webmaster, giving this error + message and the time and date of the error. </p>` [download] Which makes me pretty sure the fatals/warnings are processed as if they'd go to a browser. My guess is that you are using some form of cached web-environment (mod_perl-ish maybe?). What happens if you restart your webserver?	[reply] [d/l]

As a quick and dirty solution (I actually have this in a cgi): use warnings; use strict; sub pr { print @_, "\n" }; sub pp { print "<P>", @_, "\n" }; sub pb { print "<P><B>", @_, "</B> \n" }; sub pq { my $x= join "", @_; $x=~s!([^a-zA-Z0-9.,:;_\!?\-+*/="'`(){}\[\]\\\\@#\$^~ \n])! sprintf("&#x%x;",ord$1) !ge; $x=~s!^ \| (?= \|$)! !gm; $x=~s!\n!<BR>!g; print $x, "\n"; } BEGIN { print qq{Content-Type: text/html \nCache-Control: no-cache \n\n <HTML> +}; $SIG{__DIE__}= sub { pb "die "; pq $_[0]; pr "</HTML>"; die $_[0]; }; $SIG{__WARN__}= sub { pp "warn "; pq $_[0]; pr "</P>"; }; }; [download]	[reply] [d/l]
