NAME

Dist::Surveyor - Survey installed modules and determine the specific distribution versions they came from

SYNOPSIS

my $options = {
    opt_match => $opt_match,
    opt_perlver => $opt_perlver,
    opt_remnants => $opt_remnants,
    distro_key_mod_names => $distro_key_mod_names,
};
my @installed_releases = determine_installed_releases($options, \@libdirs);

DESCRIPTION

Surveys your huge ball of Perl modules, jammed together inside a directory, and tells you exactly which module is installed there.

For quick start, and a fine example of this module usage, see dist_surveyor.

This module have one exported function - determine_installed_releases

determine_installed_releases($options, $search_dirs)

$options includes:

opt_match

A regex qr//. If exists, will ignore modules that doesn't match this regex

opt_perlver

Skip modules that are included as core in this Perl version

opt_remnants

If true, output will include old distribution versions that have left old modules behind

distro_key_mod_names

A hash-ref, with a list of irregular named releases. i.e. 'libwww-perl' => 'LWP'.

$search_dirs is an array-ref containing the list of directories to survey.

Returns a list, where each element is a hashref representing one installed distibution. This hashref is what MetaCPAN returns for https://fastapi.metacpan.org/v1/release/$author/$release, with two additional keys:

• 'url' - that same as 'download_url', but without the hostname. can be used to download the file for your favorite mirror

• 'dist_data' - Hashref containing info about the release, i.e. percent_installed. (fully installed releases will have '100.00')

OTHERS

This module checks $::DEBUG and $::VERBOSE for obvious proposes.

This module uses Dist::Surveyor::Inquiry to communicate with MetaCPAN. Check that module's documentation for options and caching.

You can use Dist::Surveyor::MakeCpan to take the list of releases and create a mini-cpan containing them.
