NAME
Perl::Critic::Policy::ErrorHandling::RequireCarpingDESCRIPTION
The "die" and "warn" functions both report the file and line number where the exception occurred. But if someone else is using your subroutine, they usually don't care where your code blew up. Instead, they want to know where their code invoked the subroutine. The Carp module provides alternative methods that report the exception from the caller's file and line number.By default, this policy will not complain about "die" or "warn", if it can determine that the message will always result in a terminal newline. Since perl suppresses file names and line numbers in this situation, it is assumed that no stack traces are desired either and none of the Carp functions are necessary.
die "oops" if $explosion; #not ok warn "Where? Where?!" if $tiger; #not ok open my $mouth, '<', 'food' or die 'of starvation'; #not ok if (! $dentist_appointment) { warn "You have bad breath!\n"; #ok } die "$clock not set.\n" if $no_time; #ok my $message = "$clock not set.\n"; die $message if $no_time; #not ok, not obvious
If you give this policy an "allow_messages_ending_with_newlines" option in your .perlcriticrc with a false value, then this policy will disallow all uses of "die" and "warn".
[ErrorHandling::RequireCarping] allow_messages_ending_with_newlines = 0
