This module is a POE::Component::IRC plugin which uses POE::Component::IRC::Plugin for its base. It provides interface to to lookup information regarding HTML element attributes. It accepts input from public channel events, /notice messages as well as /msg (private messages); although that can be configured at will.
/notice
/msg
The functionality and arguments for each of plugin's command is described in section about cmdtriggers constructor's argument.
cmdtriggers
new
# plain and simple $irc->plugin_add( 'HTMLAttributeInfo' => POE::Component::IRC::Plugin::HTML::AttributeInfo->new ); # juicy flavor $irc->plugin_add( 'HTMLAttributeInfo' => POE::Component::IRC::Plugin::HTML::AttributeInfo->new( auto => 1, response_event => 'irc_html_attribute', banned => [ qr/aol\.com$/i ], root => [ qr/mah.net$/i ], addressed => 1, line_length => 350, trigger => qr/^attr\s+(?=\S+)/i, cmdtriggers => { list_attr => qr/^ l (?:ist)? \s* a (?:ttr (?:ibute s? )? )? \s+ (?=\S+) /xi, list_el => qr/^ l (?:ist)? \s* e (?:l (?:ements?)? )? \s+ (?=\S+) /xi, type => qr/^ t (?: ype )? \s+ (?=\S+) /xi, default => qr/^ d (?: efault )? (?: \s+ values? )? \s+ (?=\S+) /xi, deprecated => qr/^ de (?: precated )? \s+ (?=\S+) /xi, dtd => qr/^ dtd \s+ (?=\S+) /xi, comment => qr/^ c (?:omment s?)? \s+ (?=\S+) /xi, total => qr/^ to (?:tal)? /xi, }, listen_for_input => [ qw(public notice privmsg) ], eat => 1, debug => 0, ) );
The new() method constructs and returns a new POE::Component::IRC::Plugin::HTML::AttributeInfo 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. Note: you can change all these arguments dynamically by accessing your plugin object as a hashref; in other words, if you want to ban a user on the fly you can do: push @{ $your_plugin_object->{banned} }, qr/\Quser!mask@foos.com/; . The possible arguments/values are as follows:
new()
POE::Component::IRC::Plugin::HTML::AttributeInfo
plugin_add
push @{ $your_plugin_object->{banned} }, qr/\Quser!mask@foos.com/;
auto
->new( auto => 0 );
Optional. Takes either true or false values, specifies whether or not the plugin should auto respond to requests. When the auto argument is set to a true value plugin will respond to the requesting person with the results automatically. When the auto argument is set to a false value plugin will not respond and you will have to listen to the events emitted by the plugin to retrieve the results (see EMITTED EVENTS section and response_event argument for details). Defaults to: 1.
response_event
1
->new( response_event => 'event_name_to_receive_results' );
Optional. Takes a scalar string specifying the name of the event to emit when the results of the request are ready. See EMITTED EVENTS section for more information. Defaults to: irc_html_attribute
irc_html_attribute
banned
->new( banned => [ qr/aol\.com$/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.
line_length
->new( line_length => 350, );
Optional. Some commands emit quite a lot of output. The plugin will split the output into several messages if the length of the output is more than line_length characters. Defaults to: 350
350
trigger
->new( trigger => qr/^attr\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/^attr\s+(?=\S+)/i
qr/^attr\s+(?=\S+)/i
cmdtriggers => { list_attr => qr/^ l (?:ist)? \s* a (?:ttr (?:ibute s? )? )? \s+ (?=\S+) /xi, list_el => qr/^ l (?:ist)? \s* e (?:l (?:ement s?)? )? \s+ (?=\S+) /xi, type => qr/^ t (?: ype )? \s+ (?=\S+) /xi, default => qr/^ d (?: efault )? (?: \s+ value s? )? \s+ (?=\S+) /xi, deprecated => qr/^ de (?: precated )? \s+ (?=\S+) /xi, dtd => qr/^ dtd \s+ (?=\S+) /xi, comment => qr/^ c (?:omment s?)? \s+ (?=\S+) /xi, total => qr/^ to (?:tal)? /xi, },
Optional. After the trigger (see above) is stripped the plugin will match the input on command regexes specified via cmdtriggers (note the plural form) argument; if none match the user will be informed about using an invalid command to the plugin. The cmdtriggers argument takes a hashref as a value; keys of that hashref are command names and values are regexes (qr//) which trigger the command. Note: anything matching the regex will be stripped from the input so make sure it doesn't match actual data. Note 2: if you are redefining the cmdtriggers you must specify entire hashref. The possible keys/values are as follows:
qr//
list_attr
{ list_attr => qr/^ l (?:ist)? \s* a (?:ttr (?:ibute s? )? )? \s+ (?=\S+) /xi, } <Zoffix> HTMLAttrBot, attr list attributes table <HTMLAttrBot> Element TABLE has the following attributes: align, bgcolor, border, cellpadding, cellspacing, class, dir, frame, id, lang, onclick, ondblclick, onkeydown, onkeypress, onkeyup, onmousedown, onmousemove, onmouseout, onmouseover, onmouseup, rules, style, summary, title, width
The list_attr command lists all the attributes which the given element may have. Trigger defaults to: qr/^ l (?:ist)? \s* a (?:ttr (?:ibute s? )? )? \s+ (?=\S+) /xi
qr/^ l (?:ist)? \s* a (?:ttr (?:ibute s? )? )? \s+ (?=\S+) /xi

The list_el command lists all the elements to which given attribute applies. Trigger defaults to: qr/^ l (?:ist)? \s* e (?:l (?:ement s?)? )? \s+ (?=\S+) /xi
qr/^ l (?:ist)? \s* e (?:l (?:ement s?)? )? \s+ (?=\S+) /xi
type
{ type => qr/^ t (?: ype )? \s+ (?=\S+) /xi, } <Zoffix> HTMLAttrBot, attr type class <HTMLAttrBot> Attribute class's value is of type: CDATA

qr/^ t (?: ype )? \s+ (?=\S+) /xi
default
{ default => qr/^ d (?: efault )? (?: \s+ value s? )? \s+ (?=\S+) /xi, } <Zoffix> HTMLAttrBot, attr default width <HTMLAttrBot> Attribute width's default values are: #IMPLIED [ HR, IFRAME, IMG, OBJECT, TABLE, TD, TH, COL, COLGROUP, PRE ]; #REQUIRED [ APPLET ]
The default command list possible default values for the given attribute. Trigger defaults to: qr/^ d (?: efault )? (?: \s+ value s? )? \s+ (?=\S+) /xi
qr/^ d (?: efault )? (?: \s+ value s? )? \s+ (?=\S+) /xi
deprecated
{ deprecated => qr/^ de (?: precated )? \s+ (?=\S+) /xi, } <Zoffix> HTMLAttrBot, attr deprecated width <HTMLAttrBot> Attribute width is deprecated on element(s): APPLET, HR, PRE, TD, TH and NOT deprecated on element(s): COL, COLGROUP, IFRAME, IMG, OBJECT, TABLE
The deprecated command tells whether or not the given attribute is deprecated. Trigger defaults to: qr/^ de (?: precated )? \s+ (?=\S+) /xi
qr/^ de (?: precated )? \s+ (?=\S+) /xi
dtd
{ dtd => qr/^ dtd \s+ (?=\S+) /xi, } <Zoffix> HTMLAttrBot, attr dtd style <HTMLAttrBot> Attribute style appears in DTD: HTML 4.01 Strict
The dtd command lists the DTDs (Document Type Definitions) under which the given attribute is defined. Trigger defaults to: qr/^ dtd \s+ (?=\S+) /xi
qr/^ dtd \s+ (?=\S+) /xi
comment
{ comment => qr/^ c (?:omment s?)? \s+ (?=\S+) /xi, } <Zoffix> HTMLAttrBot, attr comment style <HTMLAttrBot> Comment for style is: associated style info <Zoffix> HTMLAttrBot, attr comment name <HTMLAttrBot> Attribute name has the following comments: N/A: [ BUTTON, TEXTAREA ]; allows applets to find each other: [ APPLET ]; field name: [ SELECT ]; for reference by usemap: [ MAP ]; metainformation name: [ META ]; name of form for scripting: [ FORM ]; name of frame for targetting: [ FRAME, IFRAME ]; name of image for scripting: [ IMG ]; named link end: [ <HTMLAttrBot> A ]; property name: [ PARAM ]; submit as part of form: [ INPUT, OBJECT ]
The comment command lists the "comments" for the given attribute. Trigger defaults to: qr/^ c (?:omment s?)? \s+ (?=\S+) /xi
qr/^ c (?:omment s?)? \s+ (?=\S+) /xi
total
{ total => qr/^ to (?:tal)? /xi, } <Zoffix> HTMLAttrBot, attr total <HTMLAttrBot> I know of 119 attributes in total
The total command doesn't do much; it does not take any input and only lists the number of attributes which are known to the plugin. Trigger defaults to: qr/^ to (?:tal)? /xi
qr/^ to (?:tal)? /xi
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 dtd title. 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
Nick
qr/^trig\s+/
Nick, trig dtd title
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) ]
public
notice
privmsg
( listen_for_input =
[ 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
PCI_EAT_NONE
PCI_EAT_ALL
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.
0
$VAR1 = { 'out' => [ 'Attribute width is deprecated on element(s): APPLET, HR, PRE, TD, TH and NOT deprecated on element(s): COL, COLGROUP, IFRAME, IMG, OBJECT, TABLE' ], 'who' => 'Zoffix!Zoffix@irc.zoffix.com', 'what' => 'de width', 'type' => 'public', 'channel' => '#zofbot', 'message' => 'HTMLAttrBot, attr de width' };
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_html_attribute) will receive input every time request is completed. The input will come in $_[ARG0] in a form of a hashref. The possible keys/values of that hashref are as follows:
$_[ARG0]
out
{ 'out' => [ 'Attribute width is deprecated on element(s): APPLET, HR, PRE, TD, TH and NOT deprecated on element(s): COL, COLGROUP, IFRAME, IMG, OBJECT, TABLE' ], }
The out key will contain an arrayref which represents plugin's response (this is what you'd see as a message when auto option in constructor is on). This arrayref will contain several elements if the length of output is longer than line_length characters (see CONSTRUCTOR section).
who
{ 'who' => 'Zoffix!Zoffix@irc.zoffix.com', }
The who key will contain the usermask of the user who made the request.
what
{ 'what' => 'de width', }
The what key will contain user's message after trigger was stripped but before any of the cmdtriggers are stripped (see CONSTRUCTOR for description of trigger and cmdtriggers arguments)
message
{ 'message' => 'HTMLAttrBot, attr de width' }
The message key will contain user's full message (before any cmdtriggers are stripped).
{ 'type' => 'public', }
The type key will contain the "type" of the message sent by the requester. 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
{ 'channel' => '#zofbot', }
The channel key will contain the name of the channel from which the request came. This will only make sense when type key (see above) contains public.
