Naturally nodes with a width greater than 2 chars breaks it :)
Thank you anonymonk. That handles everything I've thrown at it -- which it a darn sight more than I can say for my attempts so far.
It occasionally produces an oddity -- see the 'wxyz' nodes in the second example and the '1' node in the last two examples -- but they are still clear enough for my purposes.

I'm going to try and adapt it to produce a slightly different style of output that I think results in nicer -- cleaner, more easily read -- output. Eg. Instead of: _____/\_____
___________/\_ ___/\
_______________/\_ /\_ /\_ z
___/\_____ /\_____ t /\ w /\
_/\_ _/\___ n _/\_ u v x y
_/\ /\ _/\ _/\_ _/\ /\
/\ c d e /\ h /\ /\_ /\ q r s
a b f g i j k /\ o p
l m
This: _______
___________/ \___
___________/ \_ _/ \
_______/ \_____ / \_ / \_ z
_/ \___ / \_ t / \ w / \
_/ \_ _/ \__ n _/ \_ u v x y
_/ \ / \ _/ \ _/ \ _/ \ / \
/ \ c d e / \ h / \ /\_ / \ q r s
a b f g i j k / \ o p
l m
Also, one possibility for handling node 'names' of more than 1 or 2 chars; though I'm not sure it really works as is?: _______
___________/ \___
___________/ \_ _/ \
_______/ \_____ / \_ / \_ z
_/ \___ / \_ t / \ w / \ u
_/ \_ _/ \__ n _/ \_ a u v h x y l
_/ \ / \ _/ \ _/ \ o _/ \ / \ n n i i r a u

I also finally succeeded neat :) it really is much easier on the eyes
Upon further testing, the anomalies
Hmm, weird. Using your tree generator from genBiaryTree my $root = do {
our $S //= 0;
srand $S if $S;
my $r;
my @a =(
'a'..'z',
1..9,
'A'..'Z',
);
$r = int( rand $#a ), splice @a, $r, 2, [ @a[ $r, $r+1 ]] while @a
+ > 1;
@a = @{ $a[0] };
\@a;
};

I was not able to reproduce the anomalies,
Okay.
- First problem: Your version of the generator is not -- for the same setting of srand-- producing the same randomly generated tree.
At first, I assumed this must be because you were using a different rand to me. I guessed you might be running on some flavour of *nix -- but then I noticed your use of notepad above -- which squashed that idea.
Then I thought you might be running some other flavour of windows perl -- perhaps Strawberry. So, I thought I'd re-generate the failing test cases using my version of the generator and supply you with the generated trees.
- Second problem: my version of the generator is no longer producing the same trees for a given value of -S=nnn!
Did I change the generator between posting and now? I don't remember, but I can only assume that something in the original code I used, that used rand has changed.
Never mind: I'll reverse engineer the output I posted back to a raw tree structure and give you that.
- Third problem: Reverse engineering this pretty form of output is extremely painstaking, laborious and painful!
But I did it!
my $root =
[
[
['a','b'],
[
[[['c','d'],[['e','f'],'g']],[['h',['i',['j','k']]],'l']],
[['m',['n',['o','p']]],'q']
]
],
[
[
[
[[[['r',[['s','t'],'u']],'v'],['w','x']],[['y','z'],]],
[
['1',[['2','3'],[['4','5'],[['6',['7',['8','9']]],['A','B']]]]],
[[['C','D'],['E','F']],'G']
]
],
[
[
[['H',[['I',['J','K']],'L']],[['M','N'],'O']],
['P',[[[['Q','R'],['S','T']],'U'],['V','W']]]
],
['X','Y']
]
],'Z'
]
]
;
Which fed to your dumper produces the same (malformed) dump that I originally posted: C:\test>anonBinTreeDumper.pl

8 9
But that raises another problem...
- Fourth problem: if you look at the raw tree above, you'll see it is malformed: [['y','z'],]; the x,y node is paired with a null node.
And that raises the final problem.
- Fifth problem: Given that the raw tree is reproduced from the pretty-printer output, there is no way to determine if the tree my generator fed your dumper was malformed; or if the malformation is a result of occlusion in the dumper output?
I don't think that it is possible for the generator to produce bad trees -- but I haven't proven that.
Looking at the spacing between the 'z' and the '1' nodes, the gap is too big, which makes me think it is a artifact of the dumper.
At that point, I manually made the simplest correction to the raw tree that (I thought) would make it valid: my $root =
[
[
['a','b'],
[
[[['c','d'],[['e','f'],'g']],[['h',['i',['j','k']]],'l']],
[['m',['n',['o','p']]],'q']
]
],
[
[
[
[[[['r',[['s','t'],'u']],'v'],['w','x']],[['y','z']]],
[
['1',[['2','3'],[['4','5'],[['6',['7',['8','9']]],['A','B']]]]],
[[['C','D'],['E','F']],'G']
]
],
[
[
[['H',[['I',['J','K']],'L']],[['M','N'],'O']],
['P',[[[['Q','R'],['S','T']],'U'],['V','W']]]
],
['X','Y']
]
],'Z'
]
]
;
and re-ran the dumper. As you can see, it still produces the identical, malformed dump:
C:\test>anonBinTreeDumper.pl

So then I fed that corrected tree to my dumper: C:\test>perl \perl64\site\lib\Tree\Dump.pm
