DESCRIPTION
    This module provides a perl interface to the Twitter APIs. It uses the
    same API definitions as Net::Twitter, but without the extra bells and
    whistles and without the additional dependencies. Same great taste, less
    filling.

    This module is related to, but is not part of the "Net::Twitter"
    distribution. It's API methods and API method documentation are
    generated from "Net::Twitter"'s internals. It exists for those who
    cannot, or prefer not to install Moose and its dependencies.

    You should consider upgrading to "Net::Twitter" for additional
    functionality, finer grained control over features, full backwards
    compatibility with older versions of "Net::Twitter", and additional
    error handling options.

MIGRATING FROM NET::TWITTER 2.x
    If you are migrating from Net::Twitter 2.12 (or an earlier version), you
    may need to make some minor changes to your application code in order to
    user Net::Twitter::Lite successfully.

    The primary difference is in error handling. Net::Twitter::Lite throws
    exceptions on error. It does not support the "get_error", "http_code",
    and "http_message" methods used in Net::Twitter 2.12 and prior versions.

    Instead of

      # DON'T!
      my $friends = $nt->friends();
      if ( $friends ) {
          # process $friends
      }

    wrap the API call in an eval block:

      # DO!
      my $friends = eval { $nt->friends() };
      if ( $friends ) {
          # process $friends
      }

    Here's a much more complex example taken from application code using
    Net::Twitter 2.12:

      # DON'T!
      my $friends = $nt->friends();
      if ( $friends ) {
          # process $friends
      }
      else {
          my $error = $nt->get_error;
          if ( ref $error ) {
              if ( ref($error) eq 'HASH' && exists $error->{error} ) {
                      $error = $error->{error};
              }
              else {
                      $error = 'Unexpected error type ' . ref($error);
              }
          }
          else {
              $error = $nt->http_code() . ": " . $nt->http_message;
          }
          warn "$error\n";
      }

    The Net::Twitter::Lite equivalent is:

      # DO!
      eval {
          my $friends = $nt->friends();
          # process $friends
      };
      warn "$@\n" if $@;
      return;

    In Net::Twitter::Lite, an error can always be treated as a string. See
    Net::Twitter::Lite::Error. The HTTP Status Code and HTTP Message are
    both available. Rather than accessing them via the Net::Twitter::Lite
    instance, you access them via the Net::Twitter::Lite::Error instance
    thrown as an error.

    For example:

      # DO!
      eval {
         my $friends = $nt->friends();
         # process $friends
      };
      if ( my $error = $@ ) {
          if ( blessed $error && $error->isa("Net::Twitter::Lite::Error)
               && $error->code() == 502 ) {
              $error = "Fail Whale!";
          }
          warn "$error\n";
      }

  Unsupported Net::Twitter 2.12 options to "new"
    Net::Twitter::Lite does not support the following Net::Twitter 2.12
    options to "new". It silently ignores them:

    no_fallback
        If Net::Twitter::Lite is unable to create an instance of the class
        specified in the "useragent_class" option to "new", it dies, rather
        than falling back to an LWP::UserAgent object. You really don't want
        a failure to create the "useragent_class" you specified to go
        unnoticed.

    twittervision
        Net::Twitter::Lite does not support the TwitterVision API. Use
        Net::Twitter, instead, if you need it.

    skip_arg_validation
        Net::Twitter::Lite does not API parameter validation. This is a
        feature. If Twitter adds a new option to an API method, you can use
        it immediately by passing it in the HASH ref to the API call.

        Net::Twitter::Lite relies on Twitter to validate its own parameters.
        An appropriate exception will be thrown if Twitter reports a
        parameter error.

    die_on_validation
        See "skip_arg_validation". If Twitter returns an bad parameter
        error, an appropriate exception will be thrown.

    arrayref_on_error
        This option allowed the following idiom in Net::Twitter 2.12:

          # DON'T!
          for my $friend ( @{ $nt->friends() } ) {
             # process $friend
          }

        The equivalent Net::Twitter::Lite code is:

          # DO!
          eval {
              for my $friend ( @{ $nt->friends() } ) {
                  # process $friend
              }
          };

  Unsupported Net::Twitter 2.12 methods
    clone
        The "clone" method was added to Net::Twitter 2.x to allow safe error
        handling in an environment where concurrent requests are handled,
        for example, when using LWP::UserAgent::POE as the
        "useragent_class". Since Net::Twitter::Lite throws exceptions
        instead of stashing them in the Net::Twitter::Lite instance, it is
        safe in a current request environment, obviating the need for
        "clone".

    get_error
    http_code
    http_message
        These methods are replaced by Net::Twitter::Lite::Error. An instance
        of that class is thrown errors are encountered.

METHODS AND ARGUMENTS
    new This constructs a "Net::Twitter::Lite" object. It takes several
        named parameters, all of them optional:

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

        password
            This is the password used to authenticate with Twitter.

        clientname
            The value for the "X-Twitter-Client-Name" HTTP header. It
            defaults to "Perl Net::Twitter::Lite".

        clientver
            The value for the "X-Twitter-Client-Version" HTTP header. It
            defaults to current version of the "Net::Twitter::Lite" module.

        clienturl
            The value for the "X-Twitter-Client-URL" HTTP header. It
            defaults to the search.cpan.org page for the
            "Net::Twitter::Lite" distribution.

        useragent_class
            The "LWP::UserAgent" compatible class used internally by
            "Net::Twitter::Lite". It defaults to "LWP::UserAgent". For POE
            based applications, consider using "LWP::UserAgent::POE".

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

        useragent
            The value for "User-Agent" HTTP header. It defaults to
            "Net::Twitter::Lite/0.01000 (Perl)".

        source
            The value used in the "source" parameter of API method calls. It
            is currently only used in the "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 "Net::Twitter::Lite" when displayed via the Twitter web
            interface. The value for this parameter is provided by Twitter
            when a Twitter application is registered. See
            <http://apiwiki.twitter.com/FAQ#HowdoIget%E2%80%9CfromMyApp%E2%8
            0%9DappendedtoupdatessentfrommyAPIapplication>.

        apiurl
            The URL for the Twitter API. This defaults to
            "http://twitter.com".

        identica
            If set to 1 (or any value that evaluates to true), apiurl
            defaults to "http://identi.ca/api".

    credentials($username, $password)
        Set the credentials for Basic Authentication. This is helpful for
        managing multiple accounts.

API METHODS AND ARGUMENTS
    Most Twitter API methods take parameters. All Net::Twitter::Lite API
    methods will accept a HASH ref of named parameters as specified in the
    Twitter API documentation. For convenience, many Net::Twitter::Lite
    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 "update" has one required parameter,
    "status". You can call "update" with a HASH ref argument:

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

    Or, you can use the convenient form:

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

    The "update" method also has an optional parameter,
    "in_reply_to_status_id". To use it, you 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 "page" parameter expect page numbers > 0.
    Twitter silently ignores invalid "page" values. So "{ page => 0 }"
    produces the same result as "{ page => 1 }".

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

    For example, These calls are equivalent:

        $nt->create_friend('net_twitter'); # screen name
        $nt->create_friend(1564061);       # numeric ID
        $nt->create_friend({ id => 'net_twitter' });
        $nt->create_friend({ screen_name => 'net_twitter' });
        $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 "id" parameter is required and "user_id" and "screen_name"
    are also parameters, using any one of them satisfies the requirement.

        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.

        Returns: ArrayRef[Status]

    rate_limit_status

        Parameters: *none*
        Required: *none*

        Returns the remaining number of API requests available to the
        requesting user before the API limit is reached for the current
        hour. Calls to rate_limit_status do not count against the rate
        limit. If authentication credentials are provided, the rate limit
        status for the authenticating user is returned. Otherwise, the rate
        limit status for the requester's IP address is returned.

        Returns: RateLimitStatus

        Parameters: id
        Required: id

        Returns extended information of a given user, specified by ID or
        screen name as per the required id parameter. This information
        includes design settings, so third party developers can theme their
        widgets according to a given user's preferences. You must be
        properly authenticated to request the page of a protected user.

        Returns: ExtendedUser

    test

        Parameters: *none*
        Required: *none*

        Returns the string "ok" status code.

        Returns: Str

    update
    update(status)

        Parameters: status, in_reply_to_status_id
        Required: status

        Updates the authenticating user's status. Requires the status
        parameter specified. A status update with text identical to the
        authenticating user's current status will be ignored.

        Returns: Status

    update_delivery_device
    update_delivery_device(device)

        Parameters: device
        Required: device

        Sets which device Twitter delivers updates to for the authenticating
        user. Sending none as the device parameter will disable IM or SMS
        updates.

        Returns: BasicUser

    update_profile

ERROR HANDLING
    When "Net::Twitter::Lite" encounters a Twitter API error or a network
    error, it throws a "Net::Twitter::Lite::Error" object. You can catch and
    process these exceptions by using "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::Lite::Error' ) {
                #... use the thrown error obj
                warn $@->error;
            }
            else {
                # something bad happened!
                die $@;
            }
        }

    "Net::Twitter::Lite::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";
        }
