|
||
=head1 DESCRIPTION | ||
|
||
This is a hopefully-complete API-compliant interface to MetaCPAN | ||
(L<https://metacpan.org>) with DWIM capabilities, to make your life easier. | ||
|
||
This module has three purposes: | ||
|
||
=over 4 | ||
|
||
=item * 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. | ||
|
||
=item * 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. | ||
|
||
=item * 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 I<"Dave">, you want to find both I<Dave Cross> and I<Dave Rolsky> (and any | ||
other I<Dave>), but you also want to search for a PAUSE ID of I<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. | ||

||
=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: I<http://api.metacpan.org/v0>. | ||
|
||
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<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 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 $mcpan = MetaCPAN::API->new( | ||
ua_args => [ agent => 'MyAgent' ], | ||
); | ||
|
||
The arguments that will be given to the L<HTTP::Tiny> user agent. | ||
|
||
This attribute is read-only (immutable), meaning that once it's set on | ||
initialize (via C<new()>), you cannot change it. If you need to, create a | ||
new instance of MetaCPAN::API. Why is it immutable? Because it's better. | ||
|
||
The default is a user agent string: B<MetaCPAN::API/$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<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 C<fetch()> method. It gets the path and JSON request. | ||
