in reply to Parsing a Tree to a Table.

Why is the question on hold at SO? Looks like someones homework alright, but to reverse tree visualisation is a valid problem and potentially useful to someone. Anyway, I hoped there would be some extra neat solution, then spent ten minutes correcting one silly mistake after another. Almost a one-liner:

#! /usr/bin/perl -ln /\|\s*$/ or /.*?--(-?)|/, splice(@a,$+[0]/3), $1 ? print join "\t", @a +[0..2], $' : push @a, $';

    If I understand it correctly, it only works for the trees of depth 4, right?

      Well, it prints as it goes, so prior knowledge of max depth is needed. (Adding this as option is trivial.)

      Note that the problem description shows four output columns, and mentions large data.
