in reply to varying length multi-dimensional hashes
Okay, here is one way to populate the hash:
#!/usr/bin/perl -w use strict; my %hash; while( <> ) { chomp $_; my @trib= grep { "" ne $_ } split /(...)/, $_; my $ref= \\%hash; while( @trib ) { $ref= \$$ref->{shift @trib}; } $$ref++; }
Note how I avoided having to save shift @trib to index into the next subhash by keeping a reference to the slot for the hash value instead of a reference to the hash.
If that code makes sense to you right away, then you are either sick, overlooking something, or do way too much work with Perl references. (:
P.S. I was seriously disappointed that
doesn't work because split doesn't set pos($_) the way /(?<=\G...)/g would. - tye (but my friends call me "Tye")my @trib= split /(?<=\G...)/, $_;
