DESCRIPTION

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

The plugin has two "modes" of functionality. First mode is displaying information about specified module (this will be the first module found on http://search.cpan.org/ matching the input). The second mode, which is referred to as search command throughout this documentation will list the names of modules from http://search.cpan.org/ which match your input. The search command is triggered by starting your search query with 'search ' word (which must be separated from the query itself by white-space).

See the end of SYNOPSYS section above for usage examples.

CONSTRUCTOR

`new`

# plain and simple
$irc->plugin_add(
    'cpan' => POE::Component::IRC::Plugin::WWW::CPAN->new
);

# juicy flavor
$irc->plugin_add(
    'cpan' =>
        POE::Component::IRC::Plugin::WWW::CPAN->new(
            mode             => 'all',
            n                => 10,
            s                => 1,
            line_length      => 350,
            auto             => 1,
            response_event   => 'irc_cpan_result',
            banned           => [ qr/aol\.com$/i ],
            addressed        => 1,
            root             => [ qr/mah.net$/i ],
            trigger          => qr/^cpan\s+(?=\S+\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::CPAN 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:

`mode`

->new( mode => 'all' );

Optional. Specifies the mode on which the plugin's search will operate. Possible values are all, module, dist and author. The same as on http://search.cpan.org/. Defaults to: all.

`n`

->new( n => 10 );

Optional. Specifies how many results to retrieve when the 'search' command is issued. As a value takes a positive integer between 1 and 100 (inclusive). Defaults to: 10

`s`

->new( s => 1 );

Optional. Applies only to the 'search' command. Specifies from which page of results on http://search.cpan.org/ to retrive the results. You definitely would want to leave it at its default value. Defaults to: 1

`line_length`

line_length => 350,

Optional. Applies only to the 'search' command. Specifies after how many characters to break up the lines (as for them not to get cut off). The actual number of characters may be less than the number specified as the plugin will not split up the names of modules on several lines. Defaults to: 350

`auto`

->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 requesting person 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.

`response_event`

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

Optional. Takes a scalar string specifying the name of the event to emit when the results of the request are ready. See EMITED EVENTS section for more information. Defaults to: irc_cpan_result

`banned`

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

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

`root`

->new( root => [ qr/\Qjust.me.and.my.friend.net\E$/i ] );

Optional. As opposed to banned argument, the root argument allows access only to people whose usermasks match any of the regexen you specify in the arrayref the argument takes as a value. By default: it is not specified. Note: as opposed to banned specifying an empty arrayref to root argument will restrict access to everyone.

`trigger`

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

Optional. Takes a regex as an argument. Messages matching this regex will be considered as requests. 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 that needs to be processed. Defaults to: qr/^cpan\s+(?=\S+\s+\S+)/i. Note: the optional 'search' command that changed plugin's output follows the trigger and is not specifiable.

`addressed`

->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 Nick and your trigger is qr/^trig\s+/ you would make the request by saying Nick, trig WWW::CPAN. 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 make a request. Note: this argument has no effect on /notice and /msg requests. Defaults to: 1

`listen_for_input`

->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 functionality only via /notice and /msg messages. Defaults to: [ qw(public notice privmsg) ]

`eat`

->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

`debug`

->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.

EMITED EVENTS

response_event - `irc_cpan_result`

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_cpan_result) will recieve input every time request is completed. The input will come in a form of a hashref. The keys/values of that hashref are as follows:

$VAR1 = {
    'who' => 'Zoffix!n=Zoffix@unaffiliated/zoffix',
    'type' => 'public',
    'channel' => '#zofbot',
    'message' => 'cpan_bot, cpan WWW::CPAN',
    'results' => [
        'WWW::CPAN v0.011 by FERREIRA "CPAN as a web service" [ http://search.cpan.org/perldoc?WWW::CPAN ]'
    ]
};

`results`

{
    'results' => [
        'WWW::CPAN v0.011 by FERREIRA "CPAN as a web service" [ http://search.cpan.org/perldoc?WWW::CPAN ]'
    ]
}

The result key will contain an arrayref of messages which are spoken to the channel/user when auto mode is turned on. If you turn off the auto mode (see CONSTRUCTOR), this is from where you would fetch the results of query.

`who`

{ 'who' => 'Zoffix!Zoffix@i.love.debian.org', }

The who key will contain the user mask of the user who sent the request.

`what`

{ 'what' => 'WWW::CPAN', }

{ 'what' => 'search WWW::CPAN', }

The what key will contain user's message after stripping the trigger (see CONSTRUCTOR).

`message`

{ 'message' => 'cpan_bot, cpan WWW::CPAN' }

The message key will contain the actual message which the user sent; that is before the trigger is stripped.

`type`

{ 'type' => 'public', }

The type key will contain the "type" of the message the user have sent. This will be either public, privmsg or notice.

`channel`

{ 'channel' => '#zofbot', }

The channel key will contain the name of the channel where the message originated. This will only make sense if type key contains public.
