Re: Unbelievably Obvious Debugging Tip

[Abigail-II]

Man, those Windows users are such lazy bastards. Too damn lazy to install a decent Unix toolkit, and too damn lazy to write a trivial Perl program. All they can do is whine that a solution is too Unix specific (never mind the fact that an open source solution for any Unix toolkit is available, not something we can say about Windows tools, can we?) Djees, you give them Perl - the portable Unix - and they still aren't satisfied.

no warnings qw /syntax/;

use Getopt::Long;

my ($show_ends, $show_tabs, $show_nonprinting);

GetOptions ("A|show-all"         =>  sub {$show_ends        = 1;
                                          $show_tabs        = 1;
                                          $show_nonprinting = 1},
            "e"                  =>  sub {$show_ends        = 1;

Took less than 15 minutes to write and test.
