The question is, for example: "What drags in APR?"

locked_user sundialsvc4 has asked for the wisdom of the Perl Monks concerning the following question:

Let’s say that, among all of the modules listed in an autobundle, I want to know which ones directly or indirectly depend upon $module_name =~ /APR/i.

In other words, “if you see insert unwanted module-name here being dragged-in to your installation, here are the modules that are causing it.”

~~Is there a~~ Heh... Where is the module or command that will find this out for me?

See require about the hooks, and caller about who called you(r) hook. `BEGIN { unshift @INC, sub { my ($self, $file) = @_; if ($file =~ /\bAPR.pm$/) { print "$file was loaded via " . caller(1); }; }; };` [download]	[reply] [d/l]

I wound up giving up (fairly quickly ...) on the `autobundle` approach, because it appeared to be doomed to causing me to install whatever was there, as opposed to whatever was (still) needed. (It’s rather amazing how much “cruft” winds up in a `PERL5LIB` over time ... almost as bad as a typical Linux distribution.) Over in this thread, http://www.perlmonks.org/?node_id=909966, I took a different approach to the problem. I decided to try to find out what the installed code actually `use`d and to automagically install that. I even came up with (and contributed ...) a somewhat cleverly lazy (if I may say so myself) utility.
