How do I get a list of installed CPAN modules?

Question

Aside from trying

perldoc <module name>

individually for any CPAN module that takes my fancy or going through the file system and looking at the directories I have no idea what modules we have installed.

What's the easiest way to just get a big list of every CPAN module installed? From the command line or otherwise.

Answer 1

perldoc -q installed

claims that cpan -l will do the trick, however it's not working for me. The other option:

cpan -a

does spit out a nice list of installed packages and has the nice side effect of writing them to a file.

Answer 2

Here a script which would do the trick:

 use ExtUtils::Installed;

 my $inst = ExtUtils::Installed->new();
 my @modules = $inst->modules();
 foreach $module (@modules){
        print $module ." - ". $inst->version($module). "\n";
 }

=head1 ABOUT

This scripts lists installed cpan modules using the ExtUtils modules

=head1 FORMAT

Prints each module in the following format
<name> - <version>

=cut

Answer 3

the Perl cookbook contains several iterations of a script "pmdesc" that does what you want. Google-search for "Perl Cookbook pmdesc" and you'll find articles on other Q&A Sites, several code listings on the net, a discussion of the solution, and even some refinements.
