DESCRIPTION
This module is a POE::Component::IRC plugin which uses POE::Component::IRC::Plugin for its base. It provides means to lookup information pertaining to CSS properties (see log snippet in 'SYNOPSIS' above)
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(
'CSSPropertyInfo' =>
POE::Component::IRC::Plugin::CSS::PropertyInfo->new
);
# juicy flavor
$irc->plugin_add(
'CSSPropertyInfo' =>
POE::Component::IRC::Plugin::CSS::PropertyInfo->new(
auto => 1,
banned => [ qr/aol\.com$/i ],
root => [ qr/mah.net$/i ],
addressed => 1,
trigger => qr/^css\s+(?=\S+\s+\S+)/i,
command_triggers => {
exists => qr/^ e (?:xist s?)? \s+/xi,
initial => qr/^ i (?:nitial)? \s+/xi,
values => qr/^ v (?:alue s?)? \s+/xi,
inherited => qr/^ in (?:herit (?:ed)? )? \s+/xi,
percentages => qr/^ p (?:ercent (?:age s? )? )? \s+/xi,
applies_to => qr/^ a (?: ppl (?:y|ies))? \s* (?:to)? \s+/xi,
media => qr/^ m (?: edia)? \s* (?:type)? \s+/xi,
value_type => qr/^ v (?: alue )? \s* t (?: ypes?)? \s+/xi,
},
response_event => 'irc_css_property_info',
listen_for_input => [ qw(public notice privmsg) ],
eat => 1,
debug => 0,
)
);
The new()
method constructs and returns a new POE::Component::IRC::Plugin::CSS::PropertyInfo
object suitable to be fed to POE::Component::IRC's plugin_add
method. The constructor takes a few arguments, but all of them are optional. The possible arguments/values are as follows:
auto
->new( auto => 0 );
Optional. Takes either true or false values, specifies whether or not the plugin should auto respond to requests. When the auto
argument is set to a true value plugin will respond to the requesting person with the results automatically. When the auto
argument is set to a false value plugin will not respond and you will have to listen to the events emitted by the plugin to retrieve the results (see EMITTED EVENTS section and response_event
argument for details). Defaults to: 1
.
response_event
->new( response_event => 'event_name_to_receive_results' );
Optional. Takes a scalar string specifying the name of the event to emit when the results of the request are ready. See EMITTED EVENTS section for more information. Defaults to: irc_css_property_info
banned
->new( banned => [ qr/aol\.com$/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/^css\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 including sub triggers which are set by command_triggers
argument (see below). Defaults to: qr/^css\s+(?=\S+\s+\S+)/i
command_triggers
command_triggers => {
exists => qr/^ e (?:xist s?)? \s+/xi,
initial => qr/^ i (?:nitial)? \s+/xi,
values => qr/^ v (?:alue s?)? \s+/xi,
inherited => qr/^ in (?:herit (?:ed)? )? \s+/xi,
percentages => qr/^ p (?:ercent (?:age s? )? )? \s+/xi,
applies_to => qr/^ a (?: ppl (?:y|ies))? \s* (?:to)? \s+/xi,
media => qr/^ m (?: edia)? \s* (?:type)? \s+/xi,
value_type => qr/^ v (?: alue )? \s* t (?: ypes?)? \s+/xi,
},
Optional. After the trigger
(see above) is matched and removed a match for a particular "command" will be made. As the case is with trigger
the command_triggers
will be removed from the request string before proceeding thus make sure they don't match the data needed for the request. That data will be a name of the CSS property for all the commands except for value_type
command for which the data are CSS value types listed below. The command_triggers
argument takes a hashref with keys being command names and values being regexes. The default settings are presented in the snippet above. The commands (keys of the command_triggers
hashref) represent the following commands:
exists
exists => qr/^ e (?:xist s?)? \s+/xi,
<Zoffix> CSSInfoBot, css exists foo
<CSSInfoBot> Property 'foo' does not seem to exist
<Zoffix> CSSInfoBot, css exists float
<CSSInfoBot> Yes, property 'float' does exist
The exists
command checks whether or not CSS property exists.
initial
initial => qr/^ i (?:nitial)? \s+/xi,
<Zoffix> CSSInfoBot, css initial bar
<CSSInfoBot> Property 'bar' does not seem to exist
<Zoffix> CSSInfoBot, css initial float
<CSSInfoBot> Initial value for 'float' is none
The initial
command lists property's initial values.
values
values => qr/^ v (?:alue s?)? \s+/xi,
<Zoffix> CSSInfoBot, css values position
<CSSInfoBot> Property 'position' accepts: static | relative | absolute | fixed | inherit
The values
command lists valid values accepted by CSS property. Those will be either literal values or "value types". The link describing certain value type can be obtained by inquiring the plugin's value_type
command (see below).
inherited
inherited => qr/^ in (?:herit (?:ed)? )? \s+/xi,
<Zoffix> CSSInfoBot, css inherited color
<CSSInfoBot> Yes, 'color' is inherited
<Zoffix> CSSInfoBot, css inherited display
<CSSInfoBot> No, 'display' is not inherited
The inherited
command tells one whether or not a certain CSS property's values are inherited or not.
percentages
percentages => qr/^ p (?:ercent (?:age s? )? )? \s+/xi,
<Zoffix> CSSInfoBot, css percentages width
<CSSInfoBot> Percentages for 'width' refer to refer to width of containing block
<Zoffix> CSSInfoBot, css percentages display
<CSSInfoBot> Percetages do not apply to 'display'
The percentages
command tells one to what do the percentage values for the property refer to.
applies_to
applies_to => qr/^ a (?: ppl (?:y|ies))? \s* (?:to)? \s+/xi,
<Zoffix> CSSInfoBot, css applies to display
<CSSInfoBot> Property 'display' applies to: all elements
<Zoffix> CSSInfoBot, css applies to width
<CSSInfoBot> Property 'width' applies to: all elements but non-replaced inline elements, table rows, and row groups
The applies_to
command tells one to which elements the specified property applies.
media
media => qr/^ m (?: edia)? \s* (?:type)? \s+/xi,
<Zoffix> CSSInfoBot, css media color
<CSSInfoBot> Property 'color' belongs to visual media type(s)
<Zoffix> CSSInfoBot, css media azimut
<CSSInfoBot> Property 'azimut' belongs to aural media type(s)
The media
command tells one to which media type a certain property belongs.
value_type
value_type => qr/^ v (?: alue )? \s* t (?: ypes?)? \s+/xi,
<Zoffix> CSSInfoBot, css value type margin-width
<CSSInfoBot> Value type 'margin-width' is described on http://www.w3.org/TR/CSS21/box.html#value-def-margin-width
<Zoffix> CSSInfoBot, css value type counter
<CSSInfoBot> Value type 'counter' is described on http://www.w3.org/TR/CSS21/syndata.html#value-def-counter
Lastly, the value_type
command. It takes "value types" as an argument as opposed to CSS properties and simply returns a URI pointing to the documentation describing the value type. Possible value types are these:
margin-width
absolute-size
number
time
string
border-width
border-style
frequency
identifier
color
integer
specific-voice
relative-size
generic-voice
padding-width
angle
percentage
family-name
uri
length
generic-family
shape
counter
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 a float
. 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' => 'Property \'float\' applies to: all, but see http://www.w3.org/TR/CSS21/visuren.html#dis-pos-flo',
'who' => 'Zoffix!n=Zoffix@unaffiliated/zoffix',
'what' => 'a float',
'type' => 'public',
'channel' => '#zofbot',
'message' => 'CSSInfoBot_, css a float'
};
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_css_property_info
) will receive input every time request is completed. The input will come in a form of a hashref in $_[ARG0]
. The keys/values of that hashref are as follows:
out
{ 'out' => 'Property \'float\' applies to: all, but see http://www.w3.org/TR/CSS21/visuren.html#dis-pos-flo', }
The out
key will contain the "information message", this will be the response string containing the response to the particular command and this will be what will be sent to IRC if auto
argument to constructor is set to a true value.
what
{ 'what' => 'a float' }
The what
key will contain the command and the data associated with it. In other words what the user requested after the trigger
was stripped off, in the sample above the command is applies_to
and the property is float
.
who
{ 'who' => 'Zoffix!n=Zoffix@unaffiliated/zoffix' }
The who
key will contain the usermask of the user who sent the request.
type
{ '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 from. This will only make sense when type
key (see above) contains public
.
message
{ 'message' => 'CSSInfoBot_, css a float' }
The message
key will contain the message which the user has sent to request.
