These are the interfaces for some of the objects you'll deal with if
you code for Supybot.
ircmsgs.IrcMsg:
This is the object that represents an IRC message. It has
several methods and attributes. The most important thing
about this class, however, is that it *is* hashable, and thus
*cannot* be modified. Do not change any attributes; any code
that modifies an IRC message is *broken* and should not
exist.
Interesting Methods:
__init__: One of the more complex initializers in
a class. It can be used in three different ways:
1) It can be given a string, as one received from
the server, which it will then parse into its
separate components and instantiate the class
with those components as attributes.
2) It can be given a command, some (optional)
arguments, and a (optional) prefix, and will
instantiate the class with those components as
attributes.
3) It can be given, in addition to any of the
above arguments, a 'msg' keyword argument that
will use the attributes of msg as defaults.
This exists to make it easier to copy
messages, since the class is immutable.
__str__: This returns the message in a string form
suitable for sending to a server.
__repr__: This returns the message in a form
suitable for eval(), assuming the name "IrcMsg" is
in your namespace and is bound to this class.
Interesting Attributes:
This is the meat of this class. These are
generally what you'll be looking at with IrcMsgs.
command: This is the command of the IrcMsg --
PRIVMSG, NOTICE, WHOIS, etc.
args: This is a tuple of the arguments to the
IrcMsg. Some messages have arguments, some don't,
depending on what command they are. You are, of
course, always assured that args exists and is a
tuple, though it might be empty.
prefix: This is the hostmask of the person/server
the message is from. In general, you won't be
setting this on your outgoing messages, but
incoming messages will always have one. This is
the whole hostmask; if the message was received
from a server, it'll be the server's hostmask; if
the message was received from a user, it'll be the
whole user hostmask. In that case, however, it's
also parsed out into the nick/user/host
attributes, which are probably more useful to
check for many purposes.
nick: If the message was sent by a user, this will
be the nick of the user. If it was sent by a
server, this will be the server's name (something
like calvino.freenode.net or similar).
user: If the message was sent by a user, this will
be the user string of the user -- what they put
into their IRC client for their "full name." If
it was sent by a server, it'll be the server's
name, again.
host: If the message was sent by a user, this will
be the host portion of their hostmask. If it was
sent by a server, it'll be the server's name (yet
again :))
irclib.Irc:
This is the object to handle everything about IRC except the
actual connection to the server itself. (*NOTE* that the
object actually received by commands in subclasses of
callbacks.Privmsg is an IrcObjectProxy, which is described
later. It augments the following interface with several
methods of its own to help plugin authors.)
Interesting Methods:
The two following messages (queueMsg and
sendMsg) are the methods by far most commonly
called by plugin authors. They're generally
the only methods you need to pay attention to
if you're writing plugins.
queueMsg: Queues a message for sending to the
server. The queue is generally FIFO, but it
does prioritize messages based on their command.
sendMsg: Queues a message for sending to the
server prior to any messages in the normal
queue. This is exactly a FIFO queue, no
reordering is done at all.
The following two methods are the most important
for people writing new IrcDrivers. Otherwise,
you really don't need to pay attention to them.
feedMsg: Feeds the Irc object a message for it
handle appropriately, as well as passing it on
to callbacks.
takeMsg: If the Irc object has a message it's
ready to send to the server, this will return
it. Otherwise, it will return None.
The next several methods are of far more marginal
utility. But someone may need them, so they're
documented here.
addCallback: Takes a callback to add to the list
of callbacks in the Irc object. See the
interface for IrcCallback for more information.
getCallback: Gets a callback by name, if it is
in the Irc object's list of callbacks. If it
it isn't, returns None.
removeCallback: Removes a callback by name.
Returns a list of the callbacks removed (since
it is technically possible to have multiple
callbacks with the same name. This list may
be empty.
__init__: Requires a nick. Optional arguments
include user and ident, which default to the
nick given, password, which defaults to the empty
password, and callbacks, a list of callbacks
(which defaults to nothing, an empty list).
reset: Resets the Irc object to its original
state, as well as sends a reset() to every
callbacks.
die: Kills the IRC object and all its callbacks.
Interesting attributes:
nick: The current nick of the bot.
prefix: The current prefix of the bot.
server: The current server the bot is connected to.
network: The current network name the bot is connected to.
afterConnect: False until the bot has received a
command sent after the connection is finished --
376, 377, or 422.
state: An IrcState object for this particular
connection. See the interface for the IrcState
object for more information.
irclib.IrcCallback:
Interesting Methods:
name: Returns the name of the callback. The
default implementation simply returns the name
of the class.
__call__: Called by the Irc object with itself
and the message whenever a message is fed to
the Irc object. Nothing is done with the return
value.
inFilter: Called by the Irc object with itself
and the message whenever a message is fed to
the Irc object. The return value should be an
IrcMsg object to be passed to the next callback
in the Irc's list of callbacks. If None is
returned, all processing stops. This gives
callbacks an oppurtunity to "filter" incoming
messages before general callbacks are given
them.
outFilter: Basically equivalent to inFilter,
except instead of being called on messages
as they enter the Irc object, it's called on
messages as they leave the Irc object.
die: Called when the parent Irc is told to
die. This gives callbacks an oppurtunity to
close open files, network connections, or
databases before they're deleted.
reset: Called when the parent Irc is told to
reset (which is generally when reconnecting
to the server). Most callbacks don't need
to define this.
Interesting attributes:
priority: Determines the priority of the
callback in the Irc object's list of
callbacks. Defaults to 99; the valid range
includes 0 through sys.maxint-1 (don't use
sys.maxint itself, that's reserved for the
Misc plugin). The lower the number, the
higher the priority. High priority
callbacks are called earlier in the
inFilter cycle, earlier in the __call__
cycle, and later in the outFilter cycle --
basically, they're given the first chances
on the way in and the last chances on the
way out.
callbacks.IrcObjectProxy:
IrcObjectProxy is a proxy for an irclib.Irc instance that
serves to provide a much fuller interface for handling
replies and errors as well as to handle the nesting of
commands. This is what you'll be dealing with almost all the
time when writing commands; when writing doCommand methods
(the kind you read about in the interface description of
irclib.IrcCallback) you'll be dealing with plain old
irclib.Irc objects.
Interesting methods:
reply: Called to reply to the current message
with a string that is to be the reply.
replySuccess, replyError: These reply with the
configured responses for success and generic
error, respectively. If an additional argument
is given, it's (intelligently) appended to the
generic message to be more specific.
error: Called to send an error reply to the
current message; not only does the response
indicate an error, but commands that error out
break the nested-command chain, which is
generally useful for not confusing the user :)
errorNoCapability: Like error, except it accepts
the capability that's missing and integrates it
into the configured error message for such
things. Also accepts an additional string for a
more descriptive message, if that's what you
want.
errorPossibleBug, errorNotRegistered,
errorNoUser, errorRequiresPrivacy: These methods
reply with the appropriate configured error
message for the conditions in their names; they
all take an additional arguments to be more
specific about the conditions they indicate, but
this argument is very rarely necessary.
getRealIrc: Returns the actual Irc object being
proxied for.
replies: Sends a collection of messages to a given
target, much like reply; except in this case, the user
can configure whether the messages will be sent
one-by-one or combined into a single message. Thus, the
method accepts a "prefixer" argument, which prefixes the
messages with a given string (or according to a given
function), a "joiner" string (or function) used to join
the messages into a single message if necessary, and an
onlyPrefixFirst argument which determines whether only
the first message will be prefixed when the messages are
sent separately (it defaults to False).
