CPAN::Unpack - Unpack CPAN distributions


  use CPAN::Unpack;
  my $u = CPAN::Unpack->new;


The Comprehensive Perl Archive Network (CPAN) is a very useful collection of Perl code. It has a whole lot of module distributions. This module unpacks the latest version of each distribution. It places it in a directory of your choice with directories being the name of the distribution.

It requires a local CPAN mirror to run. You can construct one using something similar to:

  /usr/bin/rsync -av --delete /Users/acme/cpan/CPAN/

Note that a CPAN mirror can take up about 1.5G of space (and will take a while to rsync initially). Additionally, unpacking will use up about another 1.6G.

This can be handy for code metrics, searching CPAN, or just being very nosy indeed.

This uses Parse::CPAN::Packages::Fast's latest_distributions method for finding the latest distribution.
