NAME
    Net::Twitter - Perl interface to twitter.com

VERSION
    This document describes Net::Twitter version 1.07

SYNOPSIS
       #!/usr/bin/perl

       use Net::Twitter;

       my $twit = Net::Twitter->new(username=>"myuser", password=>"mypass" );

       $result = $twit->update("My current Status");

       $twit->credentials("otheruser", "otherpass");

       $result = $twit->update("Status for otheruser");

DESCRIPTION
    http://www.twitter.com provides a web 2.0 type of ubiquitous presence.
    This module allows you to set your status, as well as the statuses of
    your friends.

    You can view the latest status of Net::Twitter on it's own twitter
    timeline at http://twitter.com/net_twitter

INTERFACE
    "new(...)"
        You must supply a hash containing the configuration for the
        connection.

        Valid configuration items are:

        "username"
            Username of your account at twitter.com. This is usually your
            email address. REQUIRED.

        "password"
            Password of your account at twitter.com. REQUIRED.

        "useragent"
            OPTIONAL: Sets the User Agent header in the HTTP request. If
            omitted, this will default to
            "Net::Twitter/$Net::Twitter::Version (Perl)"

        "source"
            OPTIONAL: Sets the source name, so messages will appear as "from
            <source>" instead of "from web". Defaults to displaying "Perl
            Net::Twitter". Note: see Twitter FAQ, your client source needs
            to be included at twitter manually.

            This value will be a code which is assigned to you by Twitter.
            For example, the default value is "twitterpm", which causes
            Twitter to display the "from Perl Net::Twitter" in your
            timeline.

            Twitter claims that specifying a nonexistant code will cause the
            system to default to "from web". Some testing with invalid
            source codes has caused certain requests to fail, returning
            undef. If you don't have a code from twitter, don't set one.

        "clientname"
            OPTIONAL: Sets the X-Twitter-Client-Name: HTTP Header. If
            omitted, this defaults to "Perl Net::Twitter"

        "clientver"
            OPTIONAL: Sets the X-Twitter-Client-Version: HTTP Header. If
            omitted, this defaults to the current Net::Twitter version,
            $Net::Twitter::VERSION.

        "clienturl"
            OPTIONAL: Sets the X-Twitter-Client-URL: HTTP Header. If
            omitted, this defaults to "http://x4.net/Net-Twitter/meta.xml".
            By standard, this file should be in XML format, as at the
            default location.

        "apiurl"
            OPTIONAL. The URL of the API for twitter.com. This defaults to
            "http://twitter.com/" if not set.

        "apihost"
        "apirealm"
            OPTIONAL: If you do point to a different URL, you will also need
            to set "apihost" and "apirealm" so that the internal LWP can
            authenticate.

            "apihost" defaults to "www.twitter.com:80".

            "apirealm" defaults to "Twitter API".

        "twittervision"
            OPTIONAL: If the "twittervision" argument is passed with a true
            value, the module will enable use of the
            <http://www.twittervision.com> API. If enabled, the "show_user"
            method will include relevant location data in its response
            hashref. Also, the "update_twittervision" method will allow
            setting of the current location.

    "credentials($username, $password, $apihost, $apiurl)"
        Change the credentials for logging into twitter. This is helpful
        when managing multiple accounts.

        "apirealm" and "apihost" are optional and will default to the
        standard twitter versions if omitted.

    "http_code"
        Returns the HTTP response code of the most recent request.

    "http_message"
        Returns the HTTP response message of the most recent request.

    "update($status)"
        Set your current status. This returns a hashref containing your most
        recent status. Returns undef if an error occurs.

    "update_twittervision($location)"
        If the "twittervision" argument is passed to "new" when the object
        is created, this method will update your location setting at
        twittervision.com.

        If the "twittervision" arg is not set at object creation, this
        method will return an empty hashref, otherwise it will return a
        hashref containing the location data.

    "replies([$page])"
        Returns the 20 most recent replies (status updates prefixed with
        @username posted by users who are friends with the user being
        replied to) to the authenticating user.

    "featured()"
        This returns a hashref containing a list of the users currently
        featured on the site with their current statuses inline. Returns
        undef if an error occurs.

    "friends()" DEPRECATED
        This returns a hashref containing the most recent status of those
        you have marked as friends in twitter. Returns undef if an error

            authenticated user, in order to retrieve that user's friends.

        "page"
            Gets the 100 next most recent friends, eg "page=3".

        Net::Twitter uses LWP internally. Any environment variables that LWP
        supports should be supported by Net::Twitter. I hope.

DEPENDENCIES
        LWP::UserAgent
        JSON::Any
            Starting with version 1.04, Net::Twitter requires JSON::Any
            instead of a specific JSON handler module. Net::Twitter
            currently accepts JSON::Any's default order for loading
            handlers.

HTTP RESPONSE CODES
        The Twitter API attempts to return appropriate HTTP status codes for
        every request.

        200 OK: everything went awesome.
        304 Not Modified: there was no new data to return.
        400 Bad Request: your request is invalid, and we'll return an error
        message that tells you why. This is the status code returned if
        you've exceeded the rate limit (see below).
        401 Not Authorized: either you need to provide authentication
        credentials, or the credentials provided aren't valid.
        403 Forbidden: we understand your request, but are refusing to
        fulfill it. An accompanying error message should explain why.
        404 Not Found: either you're requesting an invalid URI or the
        resource in question doesn't exist (ex: no such user).
        500 Internal Server Error: we did something wrong. Please post to
        the group about it and the Twitter team will investigate.
        502 Bad Gateway: returned if Twitter is down or being upgraded.
        503 Service Unavailable: the Twitter servers are up, but are
        overloaded with requests. Try again later.

        You can view the HTTP code and message returned after each request
        with the "http_code" and "http_message" functions.

TWITTER SOURCES
        All tweets are set with a source, so that setting your status from
        the web interface would display as "from web", and through an
        instant messenger would show "from im".

        It is possible to request a source entry from Twitter which will
        allow your tweets to show as "from YourWidget".

        Beginning in Net::Twitter 1.07 you may set this source by passing
        the "source" parameter to the "new" constructor. See above.

        Because of this, all statuses set through Net::Twitter 1.07 and
        above will now show as "from Perl Net::Twitter" instead of "from
        web".

        For more information, see "How do I get "from [my_application]"
        appended to updates sent from my API application?" at:

        <http://groups.google.com/group/twitter-development-talk/web/api-doc
        umentation>

TWITTER TERMINOLOGY CHANGES
        As of July 19th, 2007, the Twitter team has implemented a change in
        the terminology used for friends and followers to alleviate
        confusion.

        Details of the change are at:

        <http://twitter.com/blog/2007/07/friends-followers-and-notifications
        .html>

        As there are probable changes to the Twitter API in the future, the
        Net::Twitter API has been enhanced to use the new terminology.

        People who follow you are still "followers". People you follow are
        now "following".

        It is HIGHLY recommended that you use the newer terminology in the
        Net::Twitter API as indicated. The friends terminology is
        DEPRECATED, and will begin throwing warnings to that effect in a
        future revision. It is also possible that it will be removed
        entirely in a future revision.

INCOMPATIBILITIES
        The X-Twitter-Client-Name, X-Twitter-Client-Version, and
        X-Twitter-Client-URL, headers (See: "new") are currently a de facto
        standard that have not been fully codified and accepted by Twitter.

        Though they are expected to be accepted as valid (And optional),
        they could possibly change in the future.

BUGS AND LIMITATIONS
        No bugs have been reported.

        Please report any bugs or feature requests to
        "bug-net-twitter@rt.cpan.org", or through the web interface at
        <http://rt.cpan.org>.
