NAME

Module::CheckDep::Version - List prereqs that need a version bump for an author's distributions

SYNOPSIS

    use Module::CheckDep::Version qw(check_deps);

    # list only the author's own prereqs that are behind

    check_deps('STEVEB');
    
    # list all prereqs that are behind by all authors

    check_deps('STEVEB', all => 1);

    # check only a single distribution

    check_deps('STEVEB', module => 'RPi::WiringPi');

    # return the data within a hash reference instead of printing

    check_deps('STEVEB', return => 1);

    # send in your own custom function to manage the data

    check_deps('STEVEB', handler => \&my_handler);

    sub my_handler {
        # this is the actual code from the default
        # handler

        my $dists = shift;
        
        for my $dist (keys %$dists){
            print "$dist:\n";
            for my $dep (keys %{ $dists->{$dist} }){
                print "\t$_:\n" .
                      "\t\t$dists->{$dist}{$dep}{dep_ver} -> " .
                      "$dists->{$dist}{$dep}{cur_ver}\n";
            }
            print "\n";
        }
    }

DESCRIPTION

This module retrieves all [http://cpan.org|CPAN] distributions for a single author, extracts out all of the dependencies for each distribution, then lists all dependencies that have updated versions so you're aware which prerequisite distributions are behind in version than what is currently being required.

Can list only the prerequisites that are written by the same author, or optionally all prerequisite distributions by all authors.

EXPORT_OK

We export only a single function upon request: check_deps().

FUNCTIONS

check_deps($author, [%args])

Fetches a list of a CPAN author's distributions using MetaCPAN::Client, extracts out the list of each distribution's prerequisite distributions, compares the required version listed against the currently available version and either returns or prints to the screen a list of each dependency that requires a version bump.

Parameters:

    $author

Mandatory, String: A valid CPAN author's user name.

    module => 'Some::Module'

Optional, String. The name of a valid CPAN distribution by the author specified. We'll only look up the results for this single distribution if this param is sent in.

    all => 1

Optional, Bool. By default, we'll only list prerequisites by the same $author. Setting this to true will list prereq version bumps required for all listed prerequisite distributions. Defaults to off/false.

    return => 1

Optional, Bool. By default we print results to STDOUT. Set this to true to have the data in hash reference form returned to you instead. Default is off/false.

    handler => \&function

Optional, code reference. You can send in a reference to a function you create to handle the data. See "SYNOPSIS" for an example of the format of the single hash reference we pass into your function.
