Introduction
This is the Perl interface for HexChat. If there are any problems, questions, comments or suggestions please email them to the address on the bottom of this page.
Constants
###Priorities
Xchat::PRI_HIGHESTXchat::PRI_HIGHXchat::PRI_NORMXchat::PRI_LOWXchat::PRI_LOWEST
Return values
Xchat::EAT_NONE- pass the event alongXchat::EAT_XCHAT- don't let HexChat see this eventXchat::EAT_PLUGIN- don't let other scripts and plugins see this event but xchat will still see itXchat::EAT_ALL- don't let anything else see this event
Timer and fd hooks
Xchat::KEEP- keep the timer going or hook watching the handleXchat::REMOVE- remove the timer or hook watching the handle
hook_fd flags
Xchat::FD_READ- invoke the callback when the handle is ready for readingXchat::FD_WRITE- invoke the callback when the handle is ready for writingXchat::FD_EXCEPTION- invoke the callback if an exception occursXchat::FD_NOTSOCKET- indicate that the handle being hooked is not a socket
Functions
Xchat::register( $name, $version, [$description,[$callback]] )
$name- The name of this script$version- This script's version$description- A description for this script$callback- This is a function that will be called when the is script unloaded. This can be either a reference to a function or an anonymous sub reference.
This is the first thing to call in every script.
Xchat::hook_server( $message, $callback, [\%options] )
Xchat::hook_command( $command, $callback, [\%options] )
Xchat::hook_print( $event,$callback, [\%options] )
Xchat::hook_timer( $timeout,$callback, [\%options | $data] )
Xchat::hook_fd( $handle, $callback, [ \%options ] )
These functions can be to intercept various events.
hook_server can be used to intercept any incoming message from the IRC server.
hook_command can be used to intercept any command, if the command doesn't currently exist then a new one is created.
hook_print can be used to intercept any of the events listed in Setttings -> Text Events.
hook_timer can be used to create a new timer
$message- server message to hook such as PRIVMSG$command- command to intercept, without the leading /$event- one of the events listed in Settings->Text Events$timeout- timeout in milliseconds$handle- the I/O handle you want to monitor with hook_fd. This must be something that has a fileno. See perldoc -f fileno or fileno$callback- callback function, this is called whenever the hooked event is trigged, the following are the conditions that will trigger the different hooks. This can be either a reference to a function or an anonymous sub reference.\%options- a hash reference containing addional options for the hooks
Valid keys for %options:
| data | Additional data that is to be associated with the hook. For timer hooks this value can be provided either as Xchat::hook_timer( $timeout, $cb,{data=>$data})or Xchat::hook_timer( $timeout, $cb, $data ).However, this means that hook_timer cannot be provided with a hash reference containing data as a key. example: my $options = { data => [@arrayOfStuff] }; Xchat::hook_timer( $timeout, $cb, $options ); In this example, the timer's data will be [@arrayOfStuff] and not { data => [@arrayOfStuff] } This key is valid for all of the hook functions. Default is undef. |
| priority | Sets the priority for the hook. It can be set to one of the Xchat::PRI_* constants.This key only applies to server, command and print hooks. Default is Xchat::PRI_NORM.
|
| help_text | Text displayed for /help $command. This key only applies to command hooks. Default is "". |
| flags | Specify the flags for a fd hook. See hook fd flags section for valid values. On Windows if the handle is a pipe you specify Xchat::FD_NOTSOCKET in addition to any other flags you might be using. This key only applies to fd hooks. Default is Xchat::FD_READ |
When callbacks are invoked
Each of the hooks will be triggered at different times depending on the type of hook.
| Hook Type | When the callback will be invoked |
| server hooks | a $message message is
received from the server
|
| command hooks | the $command command is
executed, either by the user or from a script
|
| print hooks | X-Chat is about to print the message for the
$event event
|
| timer hooks | called every $timeout milliseconds
(1000 millisecond is 1 second)the callback will be executed in the same context where the hook_timer was called, if the context no longer exists then it will execute in a random context |
| fd hooks | depends on the flags that were passed to hook_fd See hook_fd flags section. |
The value return from these hook functions can be passed to Xchat::unhook to remove the hook.
Callback Arguments
All callback functions will receive their arguments in @_ like every other Perl subroutine.
Server and command callbacks
$_[0] - array reference containing the IRC message or command and arguments broken into words
example:
/command arg1 arg2 arg3
$_[0][0] - command
$_[0][1] - arg1
$_[0][2] - arg2
$_[0][3] - arg3
$_[1] - array reference containing the Nth word to the last word
example:
/command arg1 arg2 arg3
$_[1][0] - command arg1 arg2 arg3
$_[1][1] - arg1 arg2 arg3
$_[1][2] - arg2 arg3
$_[1][3] - arg3
$_[2] - the data that was passed to the hook function
Print callbacks
$_[0] - array reference containing the values for the text event, see Settings -> Text Events
$_[1] - the data that was passed to the hook function
Timer callbacks
$_[0] - the data that was passed to the hook function
fd callbacks
$_[0] - the handle that was passed to hook_fd
$_[1] - flags indicating why the callback was called
$_[2] - the data that was passed to the hook function
Callback return values
All server, command and print callbacks should return one of the Xchat::EAT_* constants.
Timer callbacks can return Xchat::REMOVE to remove the timer or Xchat::KEEP to keep it going.
Miscellaneous Hook Related Information
For server hooks, if $message is "RAW LINE" then $cb> will be called for every IRC message that HexChat receives.
For command hooks if $command is "" then $cb will be called for messages entered by the user that is not a command.
For print hooks besides those events listed in Settings -> Text Events, these additional events can be used.
| Event | Description |
| "Open Context" | a new context is created |
| "Close Context" | a context has been close |
| "Focus Tab" | when a tab is brought to the front |
| "Focus Window" | when a top level window is focused or the main tab window is focused by the window manager |
| "DCC Chat Text" | when text from a DCC Chat arrives.
$_[0] will have these values$_[0][0] - Address$_[0][1] - Port$_[0][2] - Nick$_[0][3] - Message |
| "Key Press" | used for intercepting key presses $_[0][0] - key value $_[0][1] - state bitfield, 1 - shift, 4 - control, 8 - alt $_[0][2] - string version of the key which might be empty for unprintable keys $_[0][3] - length of the string in $_[0][2] |
Xchat::unhook( $hook )
$hook- the hook that was previously returned by one of theXchat::hook_*functions
This function is used to removed a hook previously added with one of the Xchat::hook_* functions.
It returns the data that was passed to the Xchat::hook_* function when the hook was added.
Xchat::print( $text | \@lines, [$channel,[$server]] )
$text- the text to print\@lines- array reference containing lines of text to be printed all the elements will be joined together before printing$channel- channel or tab with the given name where$textwill be printed$server- specifies that the text will be printed in a channel or tab that is associated with$server
The first argument can either be a string or an array reference of strings.
Either or both of $channel and $server can be undef.
If called as Xchat::print( $text ), it will always return true.
If called with either the channel or the channel and the server
specified then it will return true if a context is found and
false otherwise. The text will not be printed if the context
is not found. The meaning of setting $channel or $server to
undef is the same as find_context.
Xchat::printf( $format, LIST )
$format- a format string, see "perldoc -f sprintf" for further detailsLIST- list of values for the format fields
Xchat::command( $command | \@commands, [$channel,[$server]] )
$command- the command to execute, without the leading /\@commands- array reference containing a list of commands to execute$channel- channel or tab with the given name where$commandwill be executed$server- specifies that the command will be executed in a channel or tab that is associated with$server
The first argument can either be a string or an array reference of strings.
Either or both of $channel and $server can be undef.
If called as Xchat::command( $command ), it will always return true.
If called with either the channel or the channel and the server
specified then it will return true if a context is found and false
otherwise. The command will not be executed if the context is not found.
The meaning of setting $channel or $server to undef is the same as find_context.
Xchat::commandf( $format, LIST )
$format- a format string, see "perldoc -f sprintf" for further detailsLIST- list of values for the format fields
Xchat::find_context( [$channel, [$server]] )
$channel- name of a channel$server- name of a server
Either or both of $channel and $server can be undef. Calling
Xchat::find_context() is the same as calling Xchat::find_context( undef, undef) and
Xchat::find_context( $channel ) is the same as Xchat::find_context( $channel, undef ).
If $server is undef, find any channel named $channel. If $channel is undef, find the front most window
or tab named $server.If both $channel and $server are undef, find the currently focused tab or window.
Return the context found for one of the above situations or undef if such a context cannot be found.
Xchat::get_context()
Returns the current context.
Xchat::set_context( $context | $channel,[$server] )
$context- context value as returned fromget_context,find_contextor one of the fields in the list of hashrefs returned bylist_get$channel- name of a channel you want to switch context to$server- name of a server you want to switch context to

| win\_ptr | native window pointer, GtkWindow * on Unix, HWND on Win32. On Unix if you have the Glib module installed you can use my $window = Glib::Object->new\_from\_pointer( Xchat::get_info( "win\_ptr" ) ); to get a Gtk2::Window object. Additionally when you have detached tabs, each of the windows will return a different win\_ptr for the different Gtk2::Window objects. See char\_count.pl for a longer example of a script that uses this to show how many characters you currently have in your input box. |
|
| gtkwin_ptr | similar to win_ptr except it will always be a GtkWindow * | |
| hexchatdir | HexChat config directory encoded in UTF-8 examples: /home/user/.config/hexchat C:\Users\user\Appdata\Roaming\HexChat |
|
| hexchatdirfs | same as hexchatdir except encoded in the locale file system encoding |
This function is used to retrieve certain information about the current context. If there is an associated command then that command can be used to change the value for a particular ID.
Xchat::get_prefs( $name )
$name- name of a HexChat setting (available through the /set command)
This function provides a way to retrieve HexChat's setting information.
Returns undef if there is no setting called called $name.
Xchat::emit_print( $event, LIST )
$event- name from the Event column in Settings->Text EventsLIST- this depends on the Description column on the bottom of Settings->Text Events
This functions is used to generate one of the events listed under Settings -> Text Events.
Note: when using this function you must return Xchat::EAT_ALL otherwise you will end up with duplicate events.
One is the original and the second is the one you emit.

Send multiple mode changes for the current channel. It may send multiple MODE lines if the request doesn't fit on one.
Example:
use strict;
use warning;
use Xchat qw(:all);
hook_command( "MODES", sub {
my (undef, $who, $sign, $mode) = @{$_[0]};
my @targets = split /,/, $who;
if( @targets > 1 ) {

}
return EAT_XCHAT;
});
Xchat::nickcmp( $nick1, $nick2 )

| Key | Value |
Xchat::user_info( [$nick] )
$nick- the nick to look for, if this is not given your own nick will be used as default
This function is mainly intended to be used as a shortcut for when you need
to retrieve some information about only one user in a channel. Otherwise it
is better to use get_list. If $nick is found a hash reference containing
the same keys as those in the "users" list of get_list is returned otherwise
undef is returned. Since it relies on get_list this function can only be used in a
channel context.
Xchat::context_info( [$context] )
$context- context returned fromget_context,find_contextandget_list, this is the context that you want infomation about. If this is omitted, it will default to current context.
This function will return the information normally retrieved with get_info, except this
is for the context that is passed in. The information will be returned in the form of a
hash. The keys of the hash are the $id you would normally supply to get_info as well
as all the keys that are valid for the items in the "channels" list from get_list. Use
of this function is more efficient than calling get_list( "channels" ) and
searching through the result.
Example:
use strict;
use warnings;
use Xchat qw(:all); # imports all the functions documented on this page
register( "User Count", "0.1",
"Print out the number of users on the current channel" );
hook_command( "UCOUNT", \&display_count );
sub display_count {
prnt "There are " . context_info()->{users} . " users in this channel.";
return EAT_XCHAT;
}
Xchat::strip_code( $string )
$string- string to remove codes from
This function will remove bold, color, beep, reset, reverse and underline codes from $string.
It will also remove ANSI escape codes which might get used by certain terminal based clients.
If it is called in void context $string will be modified otherwise a modified copy of $string is returned.
Examples
Asynchronous DNS resolution with hook_fd
use strict;
use warnings;
use Xchat qw(:all);
use Net::DNS;
hook_command( "BGDNS", sub {
my $host = $_[0][1];
my $resolver = Net::DNS::Resolver->new;
my $sock = $resolver->bgsend( $host );
hook_fd( $sock, sub {
my $ready_sock = $_[0];
my $packet = $resolver->bgread( $ready_sock );
if( $packet->authority && (my @answers = $packet->answer ) ) {
if( @answers ) {
prnt "$host:";
my $padding = " " x (length( $host ) + 2);
for my $answer ( @answers ) {
prnt $padding . $answer->rdatastr . ' ' . $answer->type;
}
}
} else {
prnt "Unable to resolve $host";
}
return REMOVE;
},
{
flags => FD_READ,
});
return EAT_XCHAT;
});
