querying modules dependency tree on CPAN Xavier Noria 11-19-2004

 In order to prepare a talk about source filters for Barcelona.pm I
wonder whether I could query CPAN somehow to know which modules use
Filter::Simple.

Do you know whether that's possible?

Unless somebody's already pre-prepared such a tree, I think you'd have to
grab the tarballs and look.

Possibly some trickery with google and site:cpan.org would help you ...

Filter::Simple appears to be a core module -- which for this purpose is
not lucky. If it were *not* core and you had a program to walk the
tree, you could simply parse the Makefile.PLs rather than grabbing
entire tarballs.

The Kwalitee project is doing something to grab that data. You can
check out what they are doiing.

Alternately, you can just install every module and grep the
directory for Filter::Simple :)
