NAME MetaCPAN::Client - A comprehensive, DWIM-featured client to the MetaCPAN API VERSION version 1.003000 SYNOPSIS # simple usage my $mcpan = MetaCPAN::Client->new(); my $author = $mcpan->author('XSAWYERX'); my $dist = $mcpan->distribuion('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 () 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->dist('MetaCPAN-Client'); my $dist = $mcpan->dist($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'); Return an array (ref) of MetaCPAN::Client::Release matching all releases that are dependent on a given module. rev_deps Alias to "reverse_dependencies" described above. pod Not implemented yet. BUILDARGS Internal construction wrapper. Do not use. 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. Simple Simple searches just contain 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' }, ] } ); 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' }, ], } ); DESIGN This module has three purposes: * Provide 100% of the MetaCPAN API This module will be updated regularly on every MetaCPAN API change, and intends to provide the user with as much of the API as possible, no shortcuts. If it's documented in the API, you should be able to do it. Because of this design decision, this module has an official MetaCPAN namespace with the blessing of the MetaCPAN developers. Notice this module currently only provides the beta API, not the old soon-to-be-deprecated API. * Be lightweight, to allow flexible usage While many modules would help make writing easier, it's important to take into account how they affect your compile-time, run-time, overall memory consumption, and CPU usage. By providing a slim interface implementation, more users are able to use this module, such as long-running processes (like daemons), CLI or GUI applications, cron jobs, and more. * DWIM While it's possible to access the methods defined by the API spec, there's still a matter of what you're really trying to achieve. For example, when searching for *"Dave"*, you want to find both *Dave Cross* and *Dave Rolsky* (and any other *Dave*), but you also want to search for a PAUSE ID of *DAVE*, if one exists. This is where DWIM comes in. This module provides you with additional generic methods which will try to do what they think you want. Of course, this does not prevent you from manually using the API methods. You still have full control over that, if that's what you wish. You can (and should) read up on the general methods, which will explain how their DWIMish nature works, and what searches they run.
