Perl is dead..

game

oneliners

perl idioms
  • stolen from busunsl's homenode
  • slurp a file:  my $contents = do { local (@ARGV, $/) = $filename; <> };
  • set even elements of @list to 'bla':  $_ % 2 or $list[$_] = 'bla' for 0..$#list;
  • getting indices sorted by value: my @indices = sort { $a[$a] <=> $a[$b] } 0..$#a;
  • initialize hash elements: @hash{@array} = (1) x @array
  • assign empty string defaults: $_ = '' for grep ! defined ( $foo, $bar, $baz );
  • blank padding: $str = pack('A40',$str);

some cool use of Perl

music and sounds

other useful homenodes

THIS IS THE LAST LINE
