<title><classname>ircmsgs.IrcMsg</classname>
|
|
<para>
|
|
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 <emphasis>is</emphasis>
|
|
hashable, and thus <emphasis>cannot</emphasis> be modified.
|
|
Do not change any attributes; any code that modifies an IRC
|
|
message is <emphasis>broken</emphasis> and should not exist.

One of the more complex initializers in a class.

It can be used in three different ways:

<para>
|
|
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.

</para>

<listitem>

It can be given a command, some (optional)

arguments, and a (optional) prefix, and

components as attributes.

<para>
|

It can be given, in addition to any of the

|
above arguments, a <varname>msg</varname>
|
|
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.

This is the hostmask of the person/server the

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
|
|
<varname>nick</varname>/<varname>user</varname>/<varname>host</varname>

attributes, which are probably more useful to

check for many purposes.

Determines the priority of the callback in the

Defaults to <literal>99</literal>; the valid range

includes <literal>0</literal> through

<literal>sys.maxint-1</literal> (don't use

<literal>sys.maxint</literal> itself, that's

reserved for the <varname>Misc</varname> plugin).
|
|
The lower the number, the higher the priority.
|
|
High priority callbacks are called earlier in the
|
|
<varname>inFilter</varname> cycle, earlier in the
|
|
<varname>__call__</varname> cycle, and later in

the <varname>outFilter</varname> cycle –

basically, they're given the first chances on the

what you'll be dealing with almost all the time when writing

commands; when writing <function>doCommand</function> methods

(the kind you read about in the interface description of

with plain old <classname>irclib.Irc</classname> objects.

the capability that's missing and integrates it

into the configured error message for such things.

Also accepts an additional string for a more

These methods reply with the appropriate
|
|
configured error message for the conditions in
|
|
their names; they all take an additional arguments
|
|

|
|
indicate, but this argument is very rarely
|
|
necessary.
