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).
