gecko-dev/extensions/irc

JavaScript IRC library, bot (runs in xpcshell), and client (runs in Mozilla.)

Files You'll find...
**-------------------------------------------
irc/bslib

basic-socket library.  NSPR socket functions wrapped in an object oriented
C api.  Allows clients to connect to as many servers as desired, without
having to worry about the messy details.

**-------------------------------------------
irc/js/lib

JavaScript library files, including...

utils.js

Utility functions used throughout the other files.  Some are very useful,
some are only slightly useful.

events.js

Event and EventPump classes.  Defines a common way to create and route
events in JavaScript.  Used HEAVILY throughout the rest of the libs to
perform asychronous tasks.  Check the code for more details.

connection.js

JavaScript wrapper around the bsIConnection component, (CBSConnection).
This is intended to make it easier to port the library to other (read
non-XPCOM) JavaScript platforms, or to dump bsIConnection all-together
when the time is right.

http.js 

Retrieves documents using the HTTP protocol and a CBSConnection.  I've got
the protocol all wrong here, but it will still retrieve the root document
for a web site.  Needs more work.

irc.js

IRC Library.  Provides DOM like access to IRC.  This is what your looking
for.

dcc.js

DCC Library.  DCC is a protocol initiated over irc, and then carried out
over a Direct Client to Client (hence the name) connection.  Currently,
only DCC-Chat is supported.  Adding the rest should be straightforward.

**-------------------------------------------
irc/js/tests

Scripts to test the various libraries including...

test_matchobject.js

Tests the object pattern matching functionality of utils.js.  Also a good
reference while learning the rules for matching an object against a group of
pattern objects.  Object pattern matching is at the root of the hook
functionality provided by events.js, so look here if you need a clue.

ircbot.js

The sample bot I use to test the IRC library.  It's mostly functional,
with a few mods you could even use it to secure a channel (if that's what
you're into.)  This is a good place to look to get a feel for how the
whole thing fits together.

**-------------------------------------------
Misc. Notes...

Events By object:

The IRCServer object generates/ handles the following events.  It is generally
not advisable to override an event handler defined on the server, unless you
realize what your replacing.  Alternatley, You can hook any of these events
through the normal event hooking facilities.

onRawData:
	name			value
	set             "server"
	type            "parsedata"
	destMethod      "onParsedData"
	destObject      server (this)
	server          server (this)
	connection      CBSConnection (this.connection)
	source          the <prefix> of the message (if it exists)
	user            user object initialized with data from the message <prefix>
	params          array containing the <middle> parameters of the message
	code            the first <middle> parameter (most messages have this)
	meat            the <trailing> parameter of the message

onParsedData:
	type			<code>.toLowerCase();
	destMethod		"on" + <Code>

onTopic:
	channel			new channel (params[1])

on332: topic reply
	channel
	topic
	destObject		e.channel
	set				"channel"

on333: topic info
	channel
	topicBy
	topicDate
	destObject		e.channel
	set				"channel"

on353:	name reply (also occurs on join)  If this.usersStable == true; clear
		this.users, set usersStable = false.  Add all users in this message to
		server.channel.users (which also adds to server.users), setting isOp
		and isVoice, but not host information (because it isnt here.)
	set				"channel"
	destObject		e.channel
	channel

on366:	End of names.  set usersStable = true; so the next we see a name
		reply, we know it starts
a new list
	set				"channel"
	destObject		e.channel
	channel

on329:	/most likely/ the channel time stamp.  sent after a 366
	on some (all?) servers, not in the rev of the RFC I saw.
	set				"channel"
	destObject		e.channel
	channel
	timeStamp		Date

on324:	channel mode reply, happens in response to a /MODE <channel>.
	type			"chanmode"
	destMethod		"onChanMode"
	channel
	
onMode:	Some user issued a /MODE command relative to some channel the lib
		is active on, *OR* the client's user has changed modes.  This message
		is just an incremental update if it	relates to the channel.
	channel			IF this is in response to a USER mode change, ie, the user
					representing the bot get's set +i or such, this property
					will NOT be defined.
	type			"chanmode" or "usermode"
	destMethod		"onChanMode" or "onUserMode"
	
	
onUserMode:	 User 'me' has changed mode.  Currently ignored.

onChanMode:	User issued a MODE command in an active channel, or the client's
			user requested a mode update/ joined a new channel.
			When this event completes, the mode property of the channel in
			question will be updated with the information in the event.

			A channel.onBan event will be created for each ban that appears
			in the new mode.
	set				"channel"
	destObject		channel

onNick:	User in one of the active channels has changed their nickname.  <user>
		will be renamed on the <server> and all <channel>s in which
		they appear.
	channel
	user

onQuit: User in one of the active channels has quit IRC.  <user> will be 
		deleted from every <channel> they appear in.  <server>.<user>
		lastQuitDate and lastQuitMessage will be set.
	channel
	user		previous CIRCUser will be upgraded to a CIRCChanUser
