This module is a POE::Component::IRC plugin which uses POE::Component::IRC::Plugin for its base. It provides interface to read comics' transcriptions on IRC. It accepts input from public channel events, /notice messages as well as /msg (private messages); although that can be configured at will.



    # plain and simple
        'XKCD' => POE::Component::IRC::Plugin::WWW::XKCD::AsText->new

    # juicy flavor
        'XKCD' =>
                auto             => 1,
                response_event   => 'irc_xkcd',
                banned           => [ qr/aol\.com$/i ],
                addressed        => 1,
                trigger          => qr/^xkcd\s+(?=\S)/i,
                listen_for_input => [ qw(public notice privmsg) ],
                eat              => 1,
                debug            => 0,

The new() method constructs and returns a new POE::Component::IRC::Plugin::WWW::XKCD::AsText object suitable to be fed to POE::Component::IRC's plugin_add method. The constructor takes a few arguments, but all of them are optional. The possible arguments/values are as follows:


    ->new( auto => 0 );

Optional. Takes either true or false values, specifies whether or not the plugin should auto respond to requests. When the auto argument is set to a true value plugin will respond to the person requesting a comic with the results automatically. When the auto argument is set to a false value plugin will not respond and you will have to listen to the events emited by the plugin to retrieve the results (see EMITED EVENTS section and response_event argument for details). Defaults to: 1.


    ->new( response_event => 'event_name_to_recieve_results' );

Optional. Takes a scalar string specifying the name of the event to emit when the comic's text is retrieved. See EMITED EVENTS section for more information. Defaults to: irc_xkcd


    ->new( banned => [ qr/aol\.com$/i ] );

Optional. Takes an arrayref of regexes as a value. If the usermask of the person (or thing) requesting the comic matches any of the regexes listed in the banned arrayref, plugin will ignore the request. Defaults to: [] (no bans are set).


    ->new( trigger => qr/^xkcd\s+(?=\S)/i );

Optional. Takes a regex as an argument. Messages matching this regex will be considered as requests for a comic. See also addressed option below which is enabled by default. Note: the trigger will be removed from the message, therefore make sure your trigger doesn't match the actual data which is ment to be a comic ID number. Defaults to: qr/^xkcd\s+(?=\S)/i


    ->new( addressed => 1 );

Optional. Takes either true or false values. When set to a true value all the public messages must be addressed to the bot. In other words, if your bot's nickname is XKCDBot and your trigger is qr/^xkcd\s+/ you would request the comic by saying XKCDBot, xkcd 222. When addressed mode is turned on, the bot's nickname, including any whitespace and common punctuation character will be removed before matching the trigger (see above). When addressed argument it set to a false value, public messages will only have to match trigger regex in order to request the comic. Note: this argument has no effect on /notice and /msg requests. Defaults to: 1


    ->new( listen_for_input => [ qw(public  notice  privmsg) ] );

Optional. Takes an arrayref as a value which can contain any of the three elements, namely public, notice and privmsg which indicate which kind of input plugin should respond to. When the arrayref contains public element, plugin will respond to requests sent from messages in public channels (see addressed argument above for specifics). When the arrayref contains notice element plugin will respond to requests sent to it via /notice messages. When the arrayref contains privmsg element, the plugin will respond to requests sent to it via /msg (private messages). You can specify any of these. In other words, setting ( listen_for_input = [ qr(notice privmsg) ] )> will enable comics only via /notice and /msg messages. Defaults to: [ qw(public notice privmsg) ]


    ->new( eat => 0 );

Optional. If set to a false value plugin will return a PCI_EAT_NONE after responding. If eat is set to a true value, plugin will return a PCI_EAT_ALL after responding. See POE::Component::IRC::Plugin documentation for more information if you are interested. Defaults to: 1


    ->new( debug => 1 );

Optional. Takes either a true or false value. When debug argument is set to a true value some debugging information will be printed out. When debug argument is set to a false value no debug info will be printed. Defaults to: 0.



    $VAR1 = {
        'who' => 'Zoffix!n=Zoffix@unaffiliated/zoffix',
        'type' => 'public',
        'channel' => '#zofbot',
        'message' => 'XKCDBot, xkcd 333',
        'id' => '333',
        'text' => q|comic's text here|,

The event handler set up to handle the event, name of which you've specified in the response_event argument to the constructor (it defaults to irc_xkcd) will recieve input every time comic request is completed. The input will come in the form of a hashref in ARG0. The keys/values of that hashref are as follows:


    { 'who' => 'Zoffix!n=Zoffix@unaffiliated/zoffix' }

The who key will contain the usermask of the user who requested the comic.

    { 'type' => 'public' }

The type key will contain the "type" of the message sent by the requestor. The possible values are: public, notice and privmsg indicating that request was requested in public channel, via /notice and via /msg (private message) respectively.


    { 'channel' => '#zofbot' }

The channel key will contain the name of the channel from which the request came from. This will only make sense when type key (see above) contains public.


    { 'message' => 'XKCDBot, kxcd 333', }

The message key will contain the message which the user has sent to request the comic.


    { 'id' => '333' }

The term key will contain the ID of the comic being retrieved.


    { 'text' => 'comic text goes here' }

The text key will contain the text of the comic or an error message. You can differentiate the errors by checking if error key is set to a true value.


    { 'error' => '1' }

When error key is present it is an indication that an error occured during the retrieval of the comic (including non-existant comic IDs). The actual error message will be present in text key.
