NAME ^

MetaCPAN::Client - A comprehensive, DWIM-featured client to the MetaCPAN API

VERSION ^

version 1.011000

SYNOPSIS ^

    # simple usage
    my $mcpan  = MetaCPAN::Client->new();
    my $author = $mcpan->author('XSAWYERX');
    my $dist   = $mcpan->distribution('MetaCPAN-Client');

    # advanced usage with cache (contributed by Kent Fredric)
    use CHI;
    use WWW::Mechanize::Cached;
    use HTTP::Tiny::Mech;
    use MetaCPAN::Client;

    my $mcpan = MetaCPAN::Client->new(
      ua => HTTP::Tiny::Mech->new(
        mechua => WWW::Mechanize::Cached->new(
          cache => CHI->new(
            driver   => 'File',
            root_dir => '/tmp/metacpan-cache',
          ),
        ),
      ),
    );

    # now $mcpan caches results

DESCRIPTION ^

This is a hopefully-complete API-compliant client to MetaCPAN (https://metacpan.org) with DWIM capabilities, to make your life easier.

ATTRIBUTES ^

request

Internal attribute representing the request object making the request to MetaCPAN and analyzing the results. You probably don't want to set this, nor should you have any usage of it.

ua

If provided, MetaCPAN::Client::Request will use the user agent object instead of the default, which is HTTP::Tiny.

Then it can be used to fetch the user agent object used by MetaCPAN::Client::Request.

METHODS ^

author

    my $author = $mcpan->author('XSAWYERX');
    my $author = $mcpan->author($search_spec);

Finds an author by either its PAUSE ID or by a search spec defined by a hash reference. Since it is common to many other searches, it is explained below under SEARCH SPEC.

Return a MetaCPAN::Client::Author object on a simple search (PAUSE ID), or a MetaCPAN::Client::ResultSet object propagated with MetaCPAN::Client::Author objects on a complex (search spec based) search.

module

    my $module = $mcpan->module('MetaCPAN::Client');
    my $module = $mcpan->module($search_spec);

Finds a module by either its module name or by a search spec defined by a hash reference. Since it is common to many other searches, it is explained below under SEARCH SPEC.

Return a MetaCPAN::Client::Module object on a simple search (module name), or a MetaCPAN::Client::ResultSet object propagated with MetaCPAN::Client::Module objects on a complex (search spec based) search.

distribution

    my $dist = $mcpan->distribution('MetaCPAN-Client');
    my $dist = $mcpan->distribution($search_spec);

Finds a distribution by either its distribution name or by a search spec defined by a hash reference. Since it is common to many other searches, it is explained below under SEARCH SPEC.

Return a MetaCPAN::Client::Distribution object on a simple search (distribution name), or a MetaCPAN::Client::ResultSet object propagated with MetaCPAN::Client::Distribution objects on a complex (search spec based) search.

file

Return a MetaCPAN::Client::File object.

favorite

Return a MetaCPAN::Client::Favorite object.

rating

Return a MetaCPAN::Client::Rating object.

release

    my $release = $mcpan->release('MetaCPAN-Client');
    my $release = $mcpan->release($search_spec);

Finds a release by either its distribution name or by a search spec defined by a hash reference. Since it is common to many other searches, it is explained below under SEARCH SPEC.

Return a MetaCPAN::Client::Release object on a simple search (release name), or a MetaCPAN::Client::ResultSet object propagated with MetaCPAN::Client::Release objects on a complex (search spec based) search.

reverse_dependencies

    my $deps = $mcpan->reverse_dependencies('ElasticSearch');

all MetaCPAN::Client::Release objects of releases that are dependent on a given module, returned as MetaCPAN::Client::ResultSet.

rev_deps

Alias to reverse_dependencies described above.

recent

    my $recent = $mcpan->recent(10);
    my $recent = $mcpan->recent('today');

return the latest N releases, or all releases from today.

returns a MetaCPAN::Client::ResultSet of MetaCPAN::Client::Release.

pod

Get POD for given file/module name. returns a MetaCPAN::Client::Pod object, which supports various output formats (html, plain, x_pod & x_markdown).

    my $pod = $mcpan->pod('Moo')->html;

all

Retrieve all matches for authors/modules/distributions/favorites or releases.

    my $all_releases = $mcpan->all('releases')

When called with a second parameter containing a hash ref, will support the following keys:

fields

See SEARCH PARAMS.

   my $all_releases = $mcpan->all('releases', { fields => [...] })

es_filter

Pass a raw ElasticSearch filter structure to reduce the number of elements returned by the query.

    my $some_releases = $mcpan->all('releases', { es_filter => {...} })

BUILDARGS

Internal construction wrapper. Do not use.

SEARCH PARAMS ^

Most searches take params as an optional hash-ref argument. these params will be passed to the search action.

In non-scrolled searches, 'fields' filter is the only supported parameter ATM.

fields

Filter the fields to reduce the amount of data pulled from MetaCPAN. can be passed as a csv list or an array ref.

    my $module = $mcpan->module('Moose', { fields => "version,author" });
    my $module = $mcpan->module('Moose', { fields => [qw/version author/] });

SEARCH SPEC ^

The hash-based search spec is common to many searches. It is quite feature-rich and allows to disambiguate different types of searches.

Basic search specs just contain a hash of keys and values:

    my $author = $mcpan->author( { name => 'Micha Nasriachi' } );

    # the following is the same as ->author('MICKEY')
    my $author = $mcpan->author( { pauseid => 'MICKEY' } );

    # find all people named Dave, not covering Davids
    # will return a resultset
    my $daves = $mcpan->author( { name => 'Dave *' } );

OR

If you want to do a more complicated query that has an OR condition, such as "this or that", you can use the following syntax with the either key:

    # any author named "Dave" or "David"
    my $daves = $mcpan->author( {
        either => [
            { name => 'Dave *'  },
            { name => 'David *' },
        ]
    } );

AND

If you want to do a more complicated query that has an AND condition, such as "this and that", you can use the following syntax with the all key:

    # any users named 'John' with a Gmail account
    my $johns = $mcpan->author( {
        all => [
            { name  => 'John *'     },
            { email => '*gmail.com' },
        ]
    } );

If you want to do something even more complicated, You can also nest your queries, e.g.:

    my $gmail_daves_or_cpan_sams = $mcpan->author( {
        either => [
            { all => [ { name => 'Dave *'  },
                       { email => '*gmail.com' } ]
            },
            { all => [ { name => 'Sam *' },
                       { email => '*cpan.org' } ]
            },
        ],
    } );

NOT

If you want to filter out some of the results of an either/all query adding a NOT filter condition, such as "not these", you can use the following syntax with the not key:

    # any author named "Dave" or "David"
    my $daves = $mcpan->author( {
        either => [
            { name => 'Dave *'  },
            { name => 'David *' },
        ],
        not => [
            { email => '*gmail.com' },
        ],
    } );
