  =head1 NAME

  MetaCPAN::API::Tiny - A Tiny API client for MetaCPAN

  =head1 VERSION

  version 1.131730

  =head1 DESCRIPTION

  This is the Tiny version of L<MetaCPAN::API>. It implements a compatible API
  with a few notable exceptions:

  =over 4

  =item Attributes are direct hash access

  The attributes defined using Mo(o|u)se are now accessed via the blessed hash
  directly. There are no accessors defined to access this elements.

  =item Exception handling

  Instead of using Try::Tiny, raw evals are used. This could potentially cause
  issues, so just be aware.

  =item Testing

  Test::Fatal was replaced with an eval implementation of exception().
  Test::TinyMocker usage is retained, but may be absorbed since it is pure perl

  =back

  =head1 CLASS_METHODS

  =head2 new

  new is the constructor for MetaCPAN::API::Tiny. In the non-tiny version of this
  module, this is provided via Any::Moose built from the attributes defined. In
  the tiny version, we define our own constructor. It takes the same arguments
  and provides similar checks to MetaCPAN::API with regards to arguments passed.

  =head1 PUBLIC_METHODS

  =head2 source

      my $source = $mcpan->source(
          author  => 'DOY',
          release => 'Moose-2.0201',
          path    => 'lib/Moose.pm',
      );

  Searches MetaCPAN for a module or a specific release and returns the plain source.

  =head2 release

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

      # or
      my $result = $mcpan->release( author => 'DOY', release => 'Moose-2.0001' );

  Searches MetaCPAN for a dist.

  You can do complex searches using 'search' parameter:

      # example lifted from MetaCPAN docs
      my $result = $mcpan->release(
          search => {
              author => "OALDERS AND ",
              filter => "status:latest",
              fields => "name",
              size   => 1,
          },
      );

  =head2 pod

      my $result = $mcpan->pod( module => 'Moose' );

      # or
      my $result = $mcpan->pod(
          author  => 'DOY',
          release => 'Moose-2.0201',
          path    => 'lib/Moose.pm',
      );

  Searches MetaCPAN for a module or a specific release and returns the POD.

  =head2 module

      my $result = $mcpan->module('MetaCPAN::API');

  Searches MetaCPAN and returns a module's ".pm" file.

  =head2 file

  A synonym of L</module>

  =head2 author

      my $result1 = $mcpan->author('XSAWYERX');
      my $result2 = $mcpan->author( pauseid => 'XSAWYERX' );

  Searches MetaCPAN for a specific author.

  You can do complex searches using 'search' parameter:

      # example lifted from MetaCPAN docs
      my $result = $mcpan->author(
          search => {
              q    => 'profile.name:twitter',
              size => 1,
          },
      );

  =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 "GET" 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 "fetch()" method. It gets the path and JSON request.

  =head1 THANKS

  Overall the tests and code were ripped directly from MetaCPAN::API and
  tiny-fied. A big thanks to Sawyer X for writing the original module.

=head1 DESCRIPTION

This script creates templates of the Buildroot package files for all the
Perl/CPAN distributions required by the specified distnames. The
dependencies and metadata are fetched from https://metacpan.org/.

After running this script, it is necessary to check the generated files.
You have to manually add the license files (PERL_FOO_LICENSE_FILES variable).
For distributions that link against a target library, you have to add the
buildroot package name for that library to the DEPENDENCIES variable.

See the Buildroot documentation for details on the usage of the Perl
infrastructure.

The major version of the host perl must be aligned on the target one,
in order to work with the right CoreList data.
