SED on cygwin not working with Hex or Octal
balajesuri, yes of course, line-by-line. A bad example of overlooking the obvious!
The Perl provided doesn't work for me, however, that is another subject for another thread.
This question is, of course, answered. Thanks!

Hi,
Is there really a difference between these two, std::hex and ios::hex??
I stumbled upon reading a line, "std::ios::hex is a bitmask (8 on gcc) and works with setf(). std::hex is the operator". Is this true?
Thanks (0 Replies)

perl::critic::policy::errorhandling::requirecarping
Perl::Critic::Policy::ErrorHandling::RequireCarping(3) User Contributed Perl Documentation Perl::Critic::Policy::ErrorHandling::RequireCarping(3)
NAME
Perl::Critic::Policy::ErrorHandling::RequireCarping - Use functions from Carp instead of "warn" or "die".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
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 (! $dentist_appointment) {
warn "You have bad breath!
"; #ok
}
die "$clock not set.
" if $no_time; #ok
my $message = "$clock not set.
";
die $message if $no_time; #not ok, not obvious
CONFIGURATION
By default, this policy allows uses of "die" and "warn" ending in an explicit newline. If you give this policy an
"allow_messages_ending_with_newlines" option in your .perlcriticrc with a false value, then this policy will prohibit such uses.
[ErrorHandling::RequireCarping]
allow_messages_ending_with_newlines = 0
If you give this policy an "allow_in_main_unless_in_subroutine" option in your .perlcriticrc with a true value, then this policy will allow
"die" and "warn" in name space main:: unless they appear in a subroutine, even if they do not end in an explicit newline.
[ErrorHandling::RequireCarping]
allow_in_main_unless_in_subroutine = 1
BUGS
Should allow "die" when it is obvious that the "message" is a reference.
