If you're struggling to understand a complex app, a graph of the inheritance hierarchy can be very useful. Here's an example for TAP::Parser:
http://i82.photobucket.com/albums/j275/publius_ovidius/Geek%20Stuff/graph-5.png It's generated with this code: #!/usr/bin/env perl use strict; use warnings; use Class::Sniff 0.08; use TAP::Parser; my @sniffs = Class::Sniff->new_from_namespace({ namespace => 'TAP::Parser', universal => 1, }); my $graph = $sniffs[0]->combine_graphs( @sniffs[ 1 .. $#sniffs ] ); my $graphviz = $graph->as_graphviz(); open my $DOT, '|dot -Tpng -o graph.png' or die("Cannot open pipe to dot: $!"); print $DOT $graphviz; It should be on the CPAN soon. If you prefer, it's also on github: http://github.com/Ovid/class--sniff/tree/master Cheers, Ovid -- Buy the book - http://www.oreilly.com/catalog/perlhks/ Tech blog - http://use.perl.org/~Ovid/journal/ Twitter - http://twitter.com/OvidPerl Official Perl 6 Wiki - http://www.perlfoundation.org/perl6
