Irssi's hierarchy is something like this:
|
|
|
|
|
|
sub1 sub2
|
|
\ /
|
|
xxx IRC COMMON ICQ yyy
|
|
|____|___________|____|____|
|
|
|
|
|
GUI (gtk/gnome, qt/kde, text, none)
|
|
|
|
|
sub1 sub2 |
|
|
\ / |
|
|
xxx IRC | COMMON ICQ yyy
|
|

CORE
|

lib-config
|
|
|
|
|
|
(IRC, ICQ, xxx and yyy are chat protocols ..)
|
|
(sub1 and sub2 are submodules of IRC module, like DCC and flood protect)
|
|
|
|
|
|
Chat protocols and frontends are kept in separate modules. Common UI
|
|
and GUI modules also have the common parts which don't know anything
|
|
about the chat protocols. This should allow implementing modules to
|
|
whatever chat protocols and with whatever frontends easily.
|
|
|
|
** Signals
|
|
|
|
Communication between different modules are done with "signals". They are
|
|
not related to UNIX signals in any way, you could more like think of them
|
|
as "events" - which might be a better name for them, but I don't really
|
|
want to change it anymore :)
|
|
|
|
So, you send signal with signal_emit() and it's sent to all modules that
|
|
have grabbed it by calling signal_add() in their init function. For
|
|
example:
|
|
|
|
signal_emit("mysignal", 1, "hello");
|
|
|
|
Sends a "mysignal" function with one argument "hello" - before that, you
|
|
should have grabbed the signal somewhere else with:
|
|
|
|
static void sig_mysignal(const char *arg1)
|
|
{
|
|
/* arg1 contains "hello" */
|
|
}
|
|
|
|
signal_add("mysignal", (SIGNAL_FUNC) sig_mysignal);
|
|
|
|
There are three different signal_add() functions which you can use to
|
|
specify if you want to grab the signal first, "normally" or last. You can
|
|
also stop the signal from going any further.
|
|
|
|
Emitting signal with it's name creates a small overhead since it has to
|
|
look up the signal's numeric ID first, after which it looks up the signal
|
|
structure. This is done because if you call a signal _really_ often,
|
|
it's faster to find it with it's numeric ID instead of the string. You
|
|
can use signal_get_uniq_id() macro to convert the signal name into ID -
|
|
you'll have to do this only once! - and use signal_emit_id() to emit the
|
|
signal. Don't bother to do this unless your signal is sent (or could be
|
|
sent) several times in a second.
|
|
|
|
See src/core/signals.h for definition of the signal function, and
|
|
signals.txt for a list of signals.
|
|
|

|
|
** lib-config
|
|
|
|
Irssi depends on this for reading and saving configuration.
|
|
(created by me for irssi)
|
|
|
|
|
|
** CORE module
|
|
|
|
Provides some functionality that all other modules can use:
|
|
- signal handling
|
|
- keeping list of settings
|
|
- keeping list of /commands
|
|
- keeping track of loaded modules
|
|
- networking functions (with nonblocking connects, IPv6 support)
|
|
- handles connecting to servers
|
|
- raw logging of server's input/output data
|
|
- /EVAL support
|
|
- fgets() like function line_split() without any maximum line limits
|
|
- command line parameter handling
|
|
- miscellaneous useful little functions
|
|
- handles logging
|
|
|
|
|
|
** COMMON UI module
|
|
|
|
- knows basics about windows and window items (=channels, queries, ..)
|
|
- printtext() - parsing texts and feeding it for GUI to print.
|
|
- themes
|
|
- translation tables
|
|
- text hilighting
|
|
- command history
|
|
- user interface (/commands) for CORE's functionality
|
|
|
|
|
|
** GUI modules
|
|
|
|
- all the rest of the functionality needed for a working client.
|
|
|
|
|
|
** IRC module
|
|
|
|
* CORE
|
|
|
|
- IRC specific /commands
|
|
- flood protecting commands sent to server
|
|
- creating IRC masks based on nick/address for bans, ignores, etc.
|
|
- keeps list of channels, nicks, channel modes, bans, etc.
|
|
- keeps list of servers, server settings, irc networks,
|
|
server reconnections and irc network splits
|
|
- redirection of commands' replies
|
|
- lag detection
|
|
- ctcp support and flood protection
|
|
- Handles ignoring people
|
|
|
|
* DCC
|
|
|
|
- DCC chat, send and get
|
|
|
|
* FLOOD
|
|
|
|
- detects private or channel flooding and sends "flood" signal
|
|
- automatic ignoring when flooding
|
|
|
|
* NOTIFYLIST
|
|
|
|
- handles notifylist
|
|
|
|
|
|
** IRC UI module
|
|
|
|
- placing channels and queries in windows
|
|
- nick completion
|
|
- printing infomation of some events
