NAME
MetaCPAN::Clients - Some useful stand-alone scripts to access MetaCPAN
SYNOPSIS
Command-line tools:
metacpan_meta.pl N [PAUSEID]
metacpan_namespace.pl --module Module::Name
metacpan_namespace.pl --distro Distro-Name (or partial name)
metacpan_impact.pl --distro Distribution-Name
metacpan_reverse_dependencies.pl --distro Distro-Name
metacpan_favorite.pl <token> <file>
metacpan_old.pl
metacpan_full_dependency_list.pl Module::Name [more Module::Names]
metacpan_dependency_tree.pl Module::Name... or read the articles and check out MetaCPAN::API.
DESCRIPTION
For an explanation of the metacpan_meta.pl script see Fetching META data from Meta CPAN.
For the metacpan_namespace.pl see List all the Perl modules and distributions in a name-space using Meta CPAN.
The metacpan_reverse_dependencies.pl show the list of distributions that use the given distribution. Code taken from Test::DependentModules of Dave Rolsky.
The metacpan_favorite.pl was created by David Golden and it is explained in How to mass-favorite modules on MetaCPAN
The token is taken from https://api.metacpan.org/user (assuming you are logged in) from the key access_token, token. The input file contains lines of "Distro-Name AUTHOR release" but it can work with "Distro-Name" alone too.
metacpan_dependency_tree.pl was originally described in How to fetch the CPAN dependency tree of a Perl module?
RESULTS
Some results using these scripts show:
On December 28, 2012 we found that 17.4% of CPAN uploads have no license in the META files
On January 3, 2013 we found that 50% of the new CPAN uploads have a repository link
On February 5, 2013 we found that still about 16.6% of the recent CPAN uploads have no license and 50% no repository link in their META files.
