=head1 VERSION

version 0.51

=head1 SYNOPSIS

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

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

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

=head1 DESCRIPTION

This was the original hopefully-complete API-compliant interface to MetaCPAN (Lhttps://metacpan.org). It has now been superseded by L.

=head1 DEPRECATED

B<THIS MODULE IS DEPRECATED, DO NOT USE!>

This module has been completely rewritten to address a multitude of problems, and is now available under the new official name: L.

Please do not use this module.

=head1 ATTRIBUTES

=head2 base_url

my $mcpan = MetaCPAN::API->new(
    base_url => 'http://localhost:9999',
);

This attribute is used for REST requests. You should set it to where the MetaCPAN is accessible. By default it's already set correctly, but if you're running a local instance of MetaCPAN, or use a local mirror, or tunnel it through a local port, or any of those stuff, you would want to change this.

Default: Ihttps://fastapi.metacpan.org/v1.

This attribute is read-only (immutable), meaning that once it's set on initialize (via C<new()>), you cannot change it. If you need to, create a new instance of MetaCPAN::API. Why is it immutable? Because it's better.

=head2 ua

This attribute is used to contain the user agent used for running the REST request to the server. It is specifically set to L, so if you want to set it manually, make sure it's of HTTP::Tiny.

HTTP::Tiny is used as part of the philosophy of keeping it tiny.

This attribute is read-only (immutable), meaning that once it's set on initialize (via C<new()>), you cannot change it. If you need to, create a new instance of MetaCPAN::API. Why is it immutable? Because it's better.

=head2 ua_args

my $mcpan = MetaCPAN::API->new(
    ua_args => [ agent => 'MyAgent' ],
);

The arguments that will be given to the L user agent.

This attribute is read-only (immutable), meaning that once it's set on initialize (via C<new()>), you cannot change it. If you need to, create a new instance of MetaCPAN::API. Why is it immutable? Because it's better.

The default is a user agent string: B<MetaCPAN::API/$version>.

=head1 METHODS

=head2 fetch

my $result = $mcpan->fetch('/release/distribution/Moose');

# with parameters
my $more = $mcpan->fetch(
    '/release/distribution/Moose',
    param => 'value',
);

This is a helper method for API implementations. It fetches a path from MetaCPAN, decodes the JSON from the content variable and returns it.

You don't really need to use it, but you can in case you want to write your own extension implementation to MetaCPAN::API.

It accepts an additional hash as C parameters.

=head2 post

# /release&content={"query":{"match_all":{}},"filter":{"prefix":{"archive":"Cache-Cache-1.06"}}}
my $result = $mcpan->post(
    'release',
    {
        query  => { match_all => {} },
        filter => { prefix => { archive => 'Cache-Cache-1.06' } },
    },
);

The POST equivalent of the C<fetch()> method. It gets the path and JSON request.
