DESCRIPTION
This module is a POE::Component::IRC plugin which uses POE::Component::IRC::Plugin for its base. It provides interface to see if some URI is present in Google's cache; if it is, plugin will give the URI pointing to that page. It accepts input from public channel events, /notice
messages as well as /msg
(private messages); although that can be configured at will.
CONSTRUCTOR
new
# plain and simple
$irc->plugin_add(
'google_cache' => POE::Component::IRC::Plugin::WWW::Cache::Google->new
);
# juicy flavor
$irc->plugin_add(
'google_cache' =>
POE::Component::IRC::Plugin::WWW::Cache::Google->new(
line_length => 350,
auto => 1,
response_event => 'irc_google_cache',
banned => [ qr/aol\.com$/i ],
addressed => 1,
root => [ qr/mah.net$/i ],
trigger => qr/^cache\s+(?=\S)/i,
triggers => {
public => qr/^EXAMPLE\s+(?=\S)/i,
notice => qr/^EXAMPLE\s+(?=\S)/i,
privmsg => qr/^EXAMPLE\s+(?=\S)/i,
},
listen_for_input => [ qw(public notice privmsg) ],
eat => 1,
debug => 0,
)
);
The new()
method constructs and returns a new POE::Component::IRC::Plugin::WWW::Cache::Google
object suitable to be fed to POE::Component::IRC's plugin_add
method. The constructor takes a few arguments, but all of them are optional. The possible arguments/values are as follows:
line_length
->new( line_length => 350, );
To prevent really "smart" people from giving the plugin utterly long URIs and thus spamming the channel you can set the line_length
argument which will cut off the output if it exceeds line_length
characters (this does not include the nick of the person). Defaults to: 350
auto
->new( auto => 0 );
Optional. Takes either true or false values, specifies whether or not the plugin should auto respond to requests. When the auto
argument is set to a true value plugin will respond to the requesting person with the results automatically. When the auto
argument is set to a false value plugin will not respond and you will have to listen to the events emitted by the plugin to retrieve the results (see EMITTED EVENTS section and response_event
argument for details). Defaults to: 1
.
response_event
->new( response_event => 'event_name_to_receive_results' );
Optional. Takes a scalar string specifying the name of the event to emit when the results of the request are ready. See EMITTED EVENTS section for more information. Defaults to: irc_google_cache
banned
->new( banned => [ qr/aol\.com$/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/^cache\s+(?=\S)/i );
Optional. Takes a regex as an argument. Messages matching this regex, irrelevant of the type of the message, will be considered as requests. See also addressed option below which is enabled by default as well as triggers option which is more specific. 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/^cache\s+(?=\S)/i
triggers
->new( triggers => {
public => qr/^EXAMPLE\s+(?=\S)/i,
notice => qr/^EXAMPLE\s+(?=\S)/i,
privmsg => qr/^EXAMPLE\s+(?=\S)/i,
}
);
Optional. Takes a hashref as an argument which may contain either one or all of keys public, notice and privmsg which indicates the type of messages: channel messages, notices and private messages respectively. The values of those keys are regexes of the same format and meaning as for the trigger
argument (see above). Messages matching this regex will be considered as requests. The difference is that only messages of type corresponding to the key of triggers
hashref are checked for the trigger. Note: the trigger
will be matched irrelevant of the setting in triggers
, thus you can have one global and specific "local" triggers. See also addressed option below which is enabled by default as well as triggers option which is more specific. 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. By default not set
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 EXAMPLE
. 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
.
EMITTED EVENTS
response_event
$VAR1 = {
'out' => 'Zoffix, http://www.google.com/search?q=cache:www.zoffix.com',
'what' => 'www.zoffix.com',
'who' => 'Zoffix!n=Zoffix@unaffiliated/zoffix',
'type' => 'public',
'channel' => '#zofbot',
'message' => 'CacheBot, cache www.zoffix.com',
'cache' => bless( do{\(my $o = 'http://www.google.com/search?q=cache:www.zoffix.com')}, 'URI::http' )
};
$VAR1 = {
'out' => 'Zoffix, No google cache found for http://non.existant.com',
'what' => 'non.existant.com',
'who' => 'Zoffix!n=Zoffix@unaffiliated/zoffix',
'error' => 'Doesn\'t look like cache exists',
'type' => 'public',
'channel' => '#zofbot',
'message' => 'CacheBot, cache non.existant.com',
'cache' => bless( do{\(my $o = 'http://www.google.com/search?q=cache:non.existant.com')}, 'URI::http' )
};
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_google_cache
) will receive input every time request is completed. The input will come in $_[ARG0]
on a form of a hashref. The possible keys/values of that hashrefs are as follows:
cache
{ 'cache' => bless( do{\(my $o = 'http://www.google.com/search?q=cache:non.existant.com')}, 'URI::http' ) }
The cache
key will contain an instance of URI object pointing to the requested page in Google's cache. Note that this will be the case even if the plugin was sure the cache doesn't point to the valid page.
error
{ 'error' => 'Doesn\'t look like cache exists', }
In case of some network error or if the page does not seem to be in google's cache, the error
key will be present and its value will be the error message.
out
{ 'out' => 'Zoffix, No google cache found for http://non.existant.com', }
The out
key will contain a string of whatever the plugin would normally spit into the IRC.
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' => 'non.existant.com', }
The what
key will contain user's message after stripping the trigger
(see CONSTRUCTOR).
message
{ 'message' => 'CacheBot, cache non.existant.com' }
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
.
