NAME
MetaCPAN::API - A comprehensive, DWIM-featured API to MetaCPAN
VERSION
version 0.30
SYNOPSIS
my $mcpan = MetaCPAN::API->new();
my $author = $mcpan->author('XSAWYERX');
my $dist = $mcpan->release( distribution => 'MetaCPAN::API' );
DESCRIPTION
This is a hopefully-complete API-compliant interface to MetaCPAN
(http://search.metacpan.org) with DWIM capabilities, to make your life
easier.
This module has three purposes:
* Provide 100% of the beta 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 and
overall memory consumption.
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 generic methods, which will
explain how their DWIMish nature works, and what searches they run.
ATTRIBUTES
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: *http://beta.api.metacpan.org*.
This attribute is read-only (immutable), meaning that once it's set on
initialize (via "new()"), you cannot change it. If you need to, create a
new instance of MetaCPAN::API. Why is it immutable? Because it's better.
ua
This attribute is used to contain the user agent used for running the
REST request to the server. It is specifically set to HTTP::Tiny, 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 "new()"), you cannot change it. If you need to, create a
new instance of MetaCPAN::API. Why is it immutable? Because it's better.
ua_args
my $mcpan = MetaCPAN::API->new(
ua_args => [ agent => 'MyAgent' ],
);
The arguments that will be given to the HTTP::Tiny user agent.
This attribute is read-only (immutable), meaning that once it's set on
initialize (via "new()"), you cannot change it. If you need to, create a

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