in thread Looking for ideas: Converting a binary 'flags' field into something human readable

I'd like to see the code that determines how to compress those together :)

    Not optimal and missing the "icycles" on the first line, but seems to work:
    لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ

      Touché!

      (Removed the "Almost :)" which was added in the light of Monk::Thomas' post; before he added the bit about downloading it wrong.)

      % perl flag_compress.pl sideways |ompressed up |lse | deleted down | bar | | that
      Hmm. Looks quite strange. But I like the idea to try to keep all annotations on the same line and if that is not possible create a new line:
          flags1 => 0b0100110000100000101000000000100000000000000101000000000000001111;
      #                | compressed   | other     | and another  |foo             | up
      #                   | deleted                                | bar           | down 
      #                    | this       | something else                            | charm
      #                         | that                                               | strange
      
      Thanks!

      Update

      Downloaded the code via wget using the download link. Output looks a lot better after converting from DOS to UNIX file format.

    use strict; use warnings; my @labels = ({label=>'compressed',start=>3}, {label=>'deleted',start= +>6}, {label=>'this',start=>7}, {label=>'that',start=>12}, {label=>'other',start=>18}, {label=>'something else',sta +rt=>20}, {label=>'and another',start=>30}, {label=>'foo',start=>4 +5}, {label=>'bar',start=>47}, {label=>'up',start=>63}, {label=>'down',start=>64}, {label=>'sideways',start=>65} +); print "0b0x00xx0000x00000x0x000000000x00000000000000x0x000000000000000 +xxx\n"; my (@lines); # for each label LOOP: foreach my $lab (@labels) { # look thru the available lines foreach my $line (@lines) { my $delta = $lab->{start} - length($line); # for a line shorter than start if ($delta >= 0) { # and tack the label on there $line .= ' ' x $delta . '|' . $lab->{label}; next LOOP; } # or fit into empty space on existing line my $len = length($lab->{label}) + 1; if (substr($line, $lab->{start}, $len) eq ' ' x $len) { substr($line, $lab->{start}, $len,'|' . $lab->{label}); next LOOP; } } # or create a new line if needed push @lines, ' ' x $lab->{start} . '|' . $lab->{label}; } print "$_\n" for @lines;

    UPDATE: added comments, added fitting new label into blank space, improved flow
