=head1 DESCRIPTION

This module provides a perl interface to the Twitter APIs.  See
L<http://apiwiki.twitter.com/Twitter-API-Documentation> for a full description
of the Twitter APIs.

=head1 OMG! THE MOOSE!

Net::Twitter is L<Moose> based. Moose provides some advantages, including the
ability for the maintainer of this module to respond quickly to Twitter API
changes.

See L<Net::Twitter::Lite> if you need an alternative without Moose and its
dependencies.

Net::Twitter::Lite's API method definitions and documentation are generated
from Net::Twitter.  It is a related module, but does not depend on
Net::Twitter or Moose for installation.

=head1 METHODS AND ARGUMENTS

=over 4

=item new

This constructs a C<Net::Twitter> object.  It takes several named parameters,
all of them optional:

=over 4

=item traits

An ARRAY ref of traits used to control which APIs the constructed
C<Net::Twitter> object will support and how it handles errors.  Possible
values are:

=over 4

=item API::REST

Provides support for the Twitter REST API methods.

=item API::Search

Provides support for the Twitter Search API methods.

=item API::TwitterVision

Provides support for the TwitterVision API.  See
L<http://twittervision.com/api.html>.

=item WrapError

C<Net::Twitter> normally throws exceptions on error.  When this trait is
included, C<Net::Twitter> returns undef when a method fails and makes the
error available through method C<get_error>.  This is the way all errors were
handled in Net::Twitter versions prior to version 3.00.

=item OAuth

The C<OAuth> trait provides OAuth authentication rather than the default Basic
Authentication for Twitter API method calls.  See the L</Authentication>
section and L<Net::Twitter::Role::OAuth> for full documentation.

=item InflateObjects

When this optional trait is included, Net::Twitter inflates HASH refs returned
by Twitter into objects with read accessors for each element.  In addition, it
inflates dates to L<DateTime> objects and URLs to L<URI> objects.  Objects that
include a C<created_at> attribute also have a C<relative_created_at> method.

For example, with C<InflateObjects> applied, the <friends_timeline> method
returns an array of status objects:

    $r = $nt->friends_timeline;
    for my $status ( @$r ) {
        $r->user->screen_name; # same as $r->{user}{screen_name}

        # $created_at is a DateTime; $age is a DateTime::Duration
        my $age = DateTime->now - $r->created_at;

        # print an age in a similar style to the Twitter web site, e.g.:
        # less than a minute ago
        # about a minute ago
        # 6 minutes ago
        # 1 day ago
        # etc.
        print $r->relative_created_at;

=item Legacy

This trait provides backwards compatibility to C<Net::Twitter> versions prior
to 3.00.  It implies the traits C<API::REST>, C<API::Search>,
C<API::TwitterVision>, and C<API::WrapError>.  It also provides additional
functionality to ensure consistent behavior for applications written for use
with legacy versions of C<Net::Twitter>.

In the current version, this trait is automatically included if the C<traits>
option is not specified. This ensures backwards compatibility for existing
applications using C<Net::Twitter> versions prior to 3.00.  See section
L</LEGACY COMPATIBILITY> for more details.

=back

Some examples of using the C<traits> parameter in C<new>:

    # provide support for *only* the REST API; throw exceptions on error
    $nt = Net::Twitter->new(traits => ['API::REST']);

    # provide support for both the REST and Search APIs; wrap errors
    $nt = Net::Twitter->new(traits => [qw/API::REST API::Search WrapError/]);

    # ensure full legacy support
    $nt = Net::Twitter->new(traits => ['Legacy']);

    # currently, these 2 calls to new are equivalent:
    $nt = Net::Twitter->new();
    $nt = Net::Twitter->new(traits => ['Legacy']);

=item legacy

A boolean.  If set to 0, C<new> constructs a C<Net::Twitter> object
implementing the REST API and throws exceptions on API method errors.

    Net::Twitter->new(legacy => 0);

is a shortcut for:

    Net::Twitter->new(traits => ['API::REST']);

If set to 1, C<new> constructs a C<Net::Twitter> object with the C<Legacy> trait.

    Net::Twitter->new(legacy => 1);

is a shortcut for:

    Net::Twitter->new(traits => ['Legacy']);

=item username

This is the screen name or email used to authenticate with Twitter.

=item password

This is the password used to authenticate with Twitter.

=item clientname

The value for the C<X-Twitter-Client-Name> HTTP header. It defaults to "Perl
Net::Twitter".

=item clientver

The value for the C<X-Twitter-Client-Version> HTTP header. It defaults to
current version of the C<Net::Twitter> module.

=item clienturl

The value for the C<X-Twitter-Client-URL> HTTP header. It defaults to the
search.cpan.org page for the C<Net::Twitter> distribution.

=item useragent_class

The C<LWP::UserAgent> compatible class used internally by C<Net::Twitter>.  It
defaults to "LWP::UserAgent".  For L<POE> based applications, consider using
"LWP::UserAgent::POE".

=item useragent_args

An HASH ref of arguments to pass to constructor of the class specified with
C<useragent_class>, above.  It defaults to {} (an empty HASH ref).

=item useragent

The value for C<User-Agent> HTTP header.  It defaults to
"Net::Twitter/$VERSION (Perl)", where C<$VERSION> is the current version of
C<Net::Twitter>.

=item source

The value used in the C<source> parameter of API method calls. It is currently
only used in the C<update> method in the REST API.  It defaults to
"twitterpm".  This results in the text "from Net::Twitter" rather than "from
web" for status messages posted from C<Net::Twitter> when displayed via the
Twitter web interface.

Twitter is no longer registering source parameters.  New applications should
implement OAuth and register via L<http://twitter.com/oauth_clients>.

Only use the C<source> parameter if you have an existing, registered source
parameter from Twitter.

=item apiurl

The URL for the Twitter API. This defaults to "http://api.twitter.com/1". This
option is available when the C<API::REST> trait is included.

=item apihost

DEPRECATED - Setting the C<apiurl> is sufficient.

=item apirealm

A string containing the Twitter API realm used for Basic Authentication. It
defaults to "Twitter API".  This option is available when the C<API::REST>
trait is included.

=item identica

If set to 1, C<Net::Twitter> overrides the defaults for C<apiurl>, C<apihost>,
and C<apirealm> to "http://identi.ca/api", "identi.ca:80", and "Laconica API"
respectively.  It defaults to 0.  This option is available when the
C<API::REST> trait is included.

=item consumer_key

A string containing the OAuth consumer key provided by Twitter when an application
is registered.  This option is available when the C<OAuth> trait is included.

=item consumer_secret

A string containing the OAuth consumer secret.  This option is available when
the C<OAuth> trait is included.

=item ssl

If set to 1, an SSL connection will be used for all API calls. Defaults to 0.

=item netrc

(Optional) Sets the I<machine> key to look up in C<.netrc> to obtain
credentials. If set to 1, Net::Twitter will use the host portion of the
C<apiurl>.

   # in .netrc
   machine api.twitter.com
     login YOUR_TWITTER_USER_NAME
     password YOUR_TWITTER_PASSWORD
   machine semifor.twitter.com
     login semifor
     password SUPERSECRET

   # in your perl program
   $nt = Net::Twitter->new(netrc => 1);
   $nt = Net::Twitter->new(netrc => 'semifor.twitter.com');

=item decode_html_entities

Twitter encodes HTML entities in the C<text> field of statuses.  Set this
option to 1 to have them automatically decoded.  Default 0.

=back

=item credentials($username, $password)

Set the credentials for Basic Authentication.  This is helpful for managing
multiple accounts.

=item ua

Provides access to the constructed user agent object used internally by
C<Net::Twitter>.  Use it with caution.

=back

=head1 AUTHENTICATION

Twitter currently provides two authentication strategies: Basic Authentication and
OAuth.  OAuth is officially in beta, however, Twitter has expressed a desire to
deprecate Basic Authentication in the future, so consider using OAuth in your
applications.

To set up Basic Authentication in C<Net::Twitter>, provide the C<username> and
C<password> options to L</new> or call the L</credentials> method.

To set up OAuth, include the C<OAuth> trait and include the C<consumer_key> and
C<consumer_secret> options to L</new>.  See L<Net::Twitter::Role::OAuth> for
more information on using OAuth, including examples.

In addition to the arguments specified for each API method described below, an
additional C<authenticate> parameter can be passed.  To request an
C<Authorization> header, pass C<< authenticated => 1 >>; to suppress an
authentication header, pass C<< authentication => 0 >>.  Even if requested, an
Authorization header will not be added if there are no user credentials
(username and password for Basic Authentication; access tokens for OAuth).

This is probably only useful for the L</rate_limit_status> method in the REST
API, since it returns different values for an authenticated and a
non-authenticated call.

=head1 API METHODS AND ARGUMENTS

Most Twitter API methods take parameters.  All Net::Twitter API
methods will accept a HASH ref of named parameters as specified in the Twitter
API documentation.  For convenience, many Net::Twitter methods accept
simple positional arguments as documented, below.  The positional parameter
passing style is optional; you can always use the named parameters in a hash
ref if you prefer.

For example, the REST API method C<update> has one required parameter,
C<status>.  You can call C<update> with a HASH ref argument:

    $nt->update({ status => 'Hello world!' });

Or, you can use the convenient form:

    $nt->update('Hello world!');

The C<update> method also has an optional parameter, C<in_reply_to_status_id>.
To use it, you B<must> use the HASH ref form:

    $nt->update({ status => 'Hello world!', in_reply_to_status_id => $reply_to });

Convenience form is provided for the required parameters of all API methods.
So, these two calls are equivalent:

    $nt->friendship_exists({ user_a => $fred, user_b => $barney });
    $nt->friendship_exists($fred, $barney);

Many API methods have aliases.  You can use the API method name, or any of its
aliases, as you prefer.  For example, these calls are all equivalent:

    $nt->friendship_exists($fred, $barney);
    $nt->relationship_exists($fred, $barney);
    $nt->follows($fred, $barney);

Aliases support both the HASH ref and convenient forms:

    $nt->follows({ user_a => $fred, user_b => $barney });

Methods that support the C<page> parameter expect page numbers E<gt> 0.  Twitter silently
ignores invalid C<page> values.  So C<< { page => 0 } >> produces the same result
as C<< { page => 1 } >>.

=head2 Synthetic Arguments

In addition to the arguments described in the Twitter API Documentation for
each API method, Net::Twitter supports additional I<synthetic> arguments.

=over 4

=item authenticate

When set to 1, Net::Twitter will provide an Authorization header for the API
call; when set to 0, it will suppress the Authentication header.  This argument
overrides the defined authentication behavior for the API method.  It is
probably only useful for the C<rate_limit_satus> method which returns different
values for authenticated and unauthenticated calls.  See L</AUTHENTICATION> for
more details.

=item since

API methods that accept the C<since_id> argument will also accept the synthetic
C<since> argument, instead.  C<since> may be a C<Date::Time> object, an epoch
time (the number of seconds since the system epoch), or a string in the same
format returned by Twitter for the C<created_at> attribute.  Only status with a
C<created_at> time greater than C<since> will be returned by the API call.

=back

=head1 REST API Methods

These methods are provided when trait C<API::REST> is included in the C<traits>
option to C<new>.

Several of these methods accept a user ID as the C<id> parameter.  The user ID
can be either a screen name, or the users numeric ID.  To disambiguate, use
the C<screen_name> or C<user_id> parameters, instead.

For example, These calls are equivalent:

    $nt->create_friend('perl_api');    # screen name
    $nt->create_friend(1564061);       # numeric ID
    $nt->create_friend({ id => 'perl_api' });
    $nt->create_friend({ screen_name => 'perl_api' });
    $nt->create_friend({ user_id     => 1564061 });

However user_id 911 and screen_name 911 are separate Twitter accounts.  These
calls are NOT equivalent:

    $nt->create_friend(911); # interpreted as screen name
    $nt->create_friend({ user_id => 911 }); # screen name: richellis

Whenever the C<id> parameter is required and C<user_id> and C<screen_name> are
also parameters, using any one of them satisfies the requirement.

=item Parameters: since_id, max_id, count, page

=item Required: I<none>

=back

Returns the 20 most recent statuses, including retweets, posted by the
authenticating user and that user's friends. This is the equivalent of
/timeline/home on the Web.


Returns: ArrayRef[Status]

=item B<mentions>


=item alias: replies


=over 4

=item Parameters: since_id, max_id, count, page

=item Required: I<none>

=item B<new_direct_message>

=item B<new_direct_message(user, text)>



=over 4

=item Parameters: user, text, screen_name, user_id

=item Required: user, text

=back

Sends a new direct message to the specified user from the authenticating user.
Requires both the user and text parameters.  Returns the sent message when
successful.  In order to support numeric screen names, the C<screen_name> or
C<user_id> parameters may be used instead of C<user>.


Returns: DirectMessage

=item B<public_timeline>



=over 4

=item Parameters: I<none>

=item Required: I<none>

=back

Returns the 20 most recent statuses from non-protected users who have
set a custom user icon.  Does not require authentication.  Note that
the public timeline is cached for 60 seconds so requesting it more
often than that is a waste of resources.

If user credentials are provided, C<public_timeline> calls are authenticated,
so they count against the authenticated user's rate limit.  Use C<<
->public_timeline({ authenticate => 0 }) >> to make an unauthenticated call
which will count against the calling IP address' rate limit, instead.


Returns: ArrayRef[Status]

=item B<rate_limit_status>



=over 4

=item Parameters: I<none>

=item Required: I<none>

=back

Returns the remaining number of API requests available to the
authenticated user before the API limit is reached for the current hour.

Use C<< ->rate_limit_status({ authenticate => 0 }) >> to force an
unauthenticated call, which will return the status for the IP address rather
than the authenticated user. (Note: for a web application, this is the server's
IP address.)


Returns: RateLimitStatus

=item B<report_spam>

=item B<report_spam(id)>



=over 4

=item Parameters: id, user_id, screen_name

=item Required: id

=back

The user specified in the id is blocked by the authenticated user and reported as a spammer.


Returns: User

=head1 Lists API

For Lists API support, add trait C<API::Lists> to the C<traits> option in
C<new>.  The Lists API is still in beta and not finalized, so the API will
change.  Follow the Twitter API Announcement list for details:
L<http://groups.google.com/group/twitter-api-announce/>.

For full documentation of the Lists API, see L<Net::Twitter::Role::API::Lists>.

=head1 LEGACY COMPATIBILITY

This version of C<Net::Twitter> automatically includes the C<Legacy> trait if
no C<traits> option is provided to C<new>.  Therefore, these 2 calls are
currently equivalent:

    $nt = Net::Twitter->new(username => $user, password => $passwd);
    $nt = Net::Twitter->new(
        username => $user,
        password => $passwd,
        traits   => ['Legacy'],
    );

Thus, existing applications written for a prior version of C<Net::Twitter>
should continue to run, without modification, with this version.

In a future release, the default traits may change.  Prior to that change,
however, a nearer future version will add a warning if no C<traits> option is
provided to C<new>.  To avoid this warning, add an appropriate C<traits>
option to your existing application code.

=head1 ERROR HANDLING

There are currently two strategies for handling errors: throwing exceptions and
wrapping errors.  Exception handling is the newer, recommended strategy.

=head2 Wrapping Errors

When trait C<WrapError> is specified (or C<Legacy>, which includes trait
C<WrapError>), C<Net::Twitter> returns undef on error.  To retrieve information
about the error, use methods C<http_code>, C<http_message>, and C<get_error>.
These methods are described in the L<Net::Twitter::Role::WrapError>.

    if ( my $followers = $nt->followers ) {
        for my $follower ( @$followers ) {
            #...
        }
    }
    else {
        warn "HTTP message: ", $nt->http_message, "\n";
    }

Since an error is stored in the object instance, this error handling strategy
is problematic when using a user agent like C<LWP::UserAgent::POE> that
provides concurrent requests.  The error for one request can be overwritten by
a concurrent request before you have an opportunity to access it.

=head2 Exception Handling

When C<Net::Twitter> encounters a Twitter API error or a network error, it
throws a C<Net::Twitter::Error> object.  You can catch and process these
exceptions by using C<eval> blocks and testing $@:

    eval {
        my $statuses = $nt->friends_timeline(); # this might die!

        for my $status ( @$statuses ) {
            #...
        }
    };
    if ( $@ ) {
        # friends_timeline encountered an error

        if ( blessed $@ && $@->isa('Net::Twitter::Error') ) {
            #... use the thrown error obj
            warn $@->error;
        }
        else {
            # something bad happened!
            die $@;
        }
    }

C<Net::Twitter::Error> stringifies to something reasonable, so if you don't need
detailed error information, you can simply treat $@ as a string:

    eval { $nt->update($status) };
    if ( $@ ) {
        warn "update failed because: $@\n";
    }

=head1 FAQ

=over 4

=item Why does C<< ->followers({ screen_name => $friend }) >> return I<my> followers instead of C<$friends>'s?

First, check carefully to make sure you've spelled "screen_name" correctly.
Twitter sometimes discards parameters it doesn't recognize.  In this case,
the result is a list of your own followers---the same thing that would happen
if you called C<followers> without the C<screen_name> parameter.

=item How do I use the C<geocode> parameter in the Search API?

The C<geocode> parameter value includes a latitude, longitude, and radius
separated with commas.

    $r = $nt->search({ geocode => "45.511795,-122.675629,25mi" });
