=head1 NAME

Facebook::Graph::Publish::Post - Publish to a user's wall.

=head1 VERSION

version 1.1203

=head1 SYNOPSIS

 my $fb = Facebook::Graph->new;

 $fb->add_post
    ->set_message('I like beer.')
    ->publish;

 my $response = $fb->add_post
    ->set_message('I like Perl.')
    ->set_picture_uri('http://www.perl.org/i/camel_head.png')
    ->set_link_uri('http://www.perl.org/')
    ->set_link_name('Perl.org')
    ->set_link_caption('Perl is a programming language.')
    ->set_link_description('A link to the Perl web site.')
    ->publish;


=head1 DESCRIPTION

This module gives you quick and easy access to publish to a user's Facebook feed.

B<ATTENTION:> You must have the C<publish_stream> privilege to use this module.

B<TIP:> Facebook seems to use these terms interchangeably: Feed, Post, News, Wall. So if you want to publish to a user's wall, this is the mechanism you use to do that.

=head1 METHODS

=head2 to ( id )

Specify a profile id to post to. Defaults to 'me', which is the currently logged in user.


=head2 set_message ( message )

Sets the text to post to the wall.

=head3 message

A string of text.


=head2 set_picture_uri ( uri )

Sets the URI of a picture to be displayed in the message.

=head3 uri

A URI to a picture.


=head2 set_link_uri ( uri )

Sets the URI of a link that viewers can click on for more information about whatever you posted in C<set_message>.

=head3 uri

A URI to a site.


=head2 set_link_name ( name )

If you want to give the link you set in C<set_link_uri> a human friendly name, use this method.

=head2 name

A text string to be used as the name of the link.


=head2 set_link_caption ( caption )

Sets a short blurb to be displayed below the link/picture.

=head3 caption

A text string.


=head2 set_link_description ( description )

Sets a longer description of the site you're linking to. Can also be a portion of the article you're linking to.

=head3 description

A text string.


=head2 set_source ( uri )

Sets a source URI for a flash or video file.

=head3 uri

The URI you wish to set. For example if you wanted to include a YouTube video:

 $post->set_source('http://www.youtube.com/watch?v=efsJRdJ6dog');


=head2 set_actions ( actions )

Sets a list of actions (or links) that should go in the post as things people can do with the post. This allows for integration of the post with third party sites.

=head3 actions

An array reference of hash references containing C<name> / C<link> pairs.

 $post->actions([
    {
        name    => 'Click Me!',
        link    => 'http://www.somesite.com/click',
    },
    ...
 ]);

=head2 add_action ( name, link )

Adds an action to the list of actions set either by previously calling C<add_action> or by calling C<set_actions>.

=head3 name

The name of the action (the clickable label).

=head3 link

The URI of the action.



=head2 set_privacy ( setting, options )

A completely optional privacy setting.

=head2 set_properties ( properties )

"property" values assigned when the post is published. This is typically rendered as a list of links.

=head3 setting

=head3 options

A hash reference of options to tweak the privacy setting. Some options are required depending on what privacy setting you chose. See L<http://developers.facebook.com/docs/reference/api/post> for details.

 $post->set_privacy('CUSTOM', { friends => 'SOME_FRIENDS', allow => [qw( 119393 993322 )] });
