DESCRIPTION

Perl documentation based on the doc/signals.txt documentation supplied with Irssi. This page documents only those signals which are directly accessible to the Perl scripting API (as provided by the generated file src/perl/perl-signals-list.h). This file is auto-generated by the script

get-signals.pl

Additional signals are available, but must be used with care, and will require the use of [[Irssi::signal_register()|Irssi#Registering_New_Signals]].

Details on how signals are actually implemented inside Irssi can be found in the Internals article.

GOALS

The goal of this document is to describe in detail, the following information:

  • FIX THE LINKS

  • What signals exist

  • What their arguments are

  • Under what circumstances they are emitted

  • What the (default) behaviour of Irssi is on reception of them

So far, work has been primarily on the signals themselves, and their arguments. Slowly, piece by piece, details are being added about when, where and how they are emitted.

The final task will be to track what effects they produce, which is an extremely difficult task, since they are so fundamental to Irssi's operation, and many signals have large numbers of listeners which interact in complex ways.

SIGNAL DEFINITIONS

The following signals are categorised as in the original documentation, but have been revised to note Perl variable types and class names.

Arguments are passed to signal handlers in the usual way, via @_.

Core

  • gui exit

    Arguments:


      Emitted by two Irssi commands, /UPGRADE, and /QUIT. Internally, it is used to exit the GLib mainloop and shut down Irssi completely.

      * None

    Emitted as the last operation of the /QUIT command, and also by the /UPGRADE command.


  • gui dialog

    • string $type

    • string $text


  • "send command"

    Arguments:


    Emitted when a command is entered via the GUI, or by scripts via Irssi::command.


chat-protocols.c

TODO: What are CHAT_PROTOCOL_REC types? -- defined in core/chat-protocols.c

  • "chat protocol created"

    • CHAT_PROTOCOL_REC $protocol

  • "chat protocol updated"

    • CHAT_PROTOCOL_REC $protocol

  • "chat protocol destroyed"

    • CHAT_PROTOCOL_REC $protocol

channels.c

chatnets.c

  • "chatnet created"

    • CHATNET_REC $chatnet

  • "chatnet destroyed"

    • CHATNET_REC $chatnet

commands.c

  • "commandlist new"

  • "commandlist remove"

  • "error command"

    Arguments:

    • int $err

    • string $cmd

    Notes: Emitted by default command at the end of the signal chain.

    $err is an enum stored in core/commands.h. These constants are not exported to perl, and are reproduced here:

      CMDERR_OPTION_UNKNOWN     = -3, /* unknown -option */
  CMDERR_OPTION_AMBIGUOUS   = -2, /* ambiguous -option */
  CMDERR_OPTION_ARG_MISSING = -1, /* argument missing for -option */

  CMDERR_UNKNOWN,           = 0   /* unknown command */
  CMDERR_AMBIGUOUS,         = 1   /* ambiguous command */

  CMDERR_ERRNO,             = 2   /* get the error from errno */
  CMDERR_NOT_ENOUGH_PARAMS, = 3   /* not enough parameters given */
  CMDERR_NOT_CONNECTED,     = 4   /* not connected to server */
  CMDERR_NOT_JOINED,        = 5   /* not joined to any channels in this window */
  CMDERR_CHAN_NOT_FOUND,    = 6   /* channel not found */
  CMDERR_CHAN_NOT_SYNCED,   = 7   /* channel not fully synchronized yet */
  CMDERR_ILLEGAL_PROTO,     = 8   /* requires different chat protocol than the active server */
  CMDERR_NOT_GOOD_IDEA,     = 9   /* not good idea to do, -yes overrides this */
  CMDERR_INVALID_TIME,      = 10  /* invalid time specification */
  CMDERR_INVALID_CHARSET,   = 11  /* invalid charset specification */
  CMDERR_EVAL_MAX_RECURSE,  = 12  /* eval hit recursion limit */
  CMDERR_PROGRAM_NOT_FOUND  = 13  /* program not found */

  • "send command"

    Arguments:


    Emitted when a line is submitted from the input field which begins with one of the characters in /SET cmdchars.

    It is emitted first in the command handling chain, before any subsequent command <cmd> signals. The $args parameter contains the full input string.


  • "send text"

    Arguments:


    Emitted when a line is submitted from the input field which does not begin with one of the characters in /SET cmdchars. The $line parameter contains the full input line.


  • "command <cmd>"

    Arguments:


    Emitted when a command matching <cmd> is entered. $args contains only the arguments to the command, having stripped the $cmdchar . $cmd.


  • "default command"

    Arguments:


    Emitted when a line is submitted from the input field which begins with a $cmdchar, but is not a recognised command.

    # Control Keys

# Note: Control-shift-key cannot be distinguished from Control-key.

C-SPC /C-@       0
C-a              1

^               94
_               95
`               96

# Lower Case Letters

a .. z          97 .. 122

~               126

# Backspace (DEL)

DEL             127

    meta-<key> sends a 27 (ESC) followed by key value.

    Arrow keys send usual meta-stuff (\e[ABCD).

    Note: Under some conditions (App-keyboard mode), arrow keys can send \e[OA .. D instead.

    A script for testing key code output interactively can be found at

    key_test.pl

gui-printtext.c

  • "beep"

    Arguments:


    • None

    Emitted by the /BEEP command, when an ASCII BEL (\007, \a) character is printed, or via one of the settings shown with /SET beep.

    Note: The setting bell_beeps only determines whether the BEL character produces a beep signal. Signals emitted from other sources are not affected.


Perl Scripting

  • "script error"

    Arguments:


    Emitted when a Perl script generates an error, during either compilation (load-time), or during execution when an unhandled die (or equivalent fatal Carp call) occurs.

POD ERRORS

Hey! The above document had some coding errors, which are explained below:
