Re^5: Converting hash structure into a special tree

The code which I tried to run:


local $_ = join '', sort map "$_\n", map {
    join ',', reverse split /,/
    }
  map s/\.\/|\n//gr, <DATA>;

sub transpose
  {
  my $tmp = '';
  $tmp .= "\n" while s/^./ $tmp .= $&; '' /gem;
  $_ = $tmp;
  }

my @p = map quotemeta, /[^,\s]+/g;
my $lead = do { local $" = '|'; qr/(@p)/ };
1 while s/^[-| ]*\K$lead,/|-- /m;
my $line = '';
$line |= $_ for /.+/g;
my $length = length $line;
s/.+/ sprintf "%-${length}s", $& /ge;
transpose;
s/\|*\K\|/`/g;
transpose;
s/ +$//gm;
s/--(?= [|`])/  /g;
s/^/    /gm;
s/    /`-- /;
print;

It's before I tried to simplified. Speaking about simplifying. I really have no I idea what those operators do. Do you have a link where I can view them?

The code you just posted runs fine on my linux machine. Are you running it in a standard terminal? Are you trying to run it in a browser? You don't need a link, just use perldoc. Start with "perldoc perl" on your command line.	[reply]

Yes I know that it runs fine. But it does not quite do what I needed It uses a real directory data (uses fine). There is a function and it gets an array and I'm not sure how the array format should look like	[reply]
