# HexChat Perl Interface ## 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_HIGHEST`** * **`Xchat::PRI_HIGH`** * **`Xchat::PRI_NORM`** * **`Xchat::PRI_LOW`** * **`Xchat::PRI_LOWEST`** ### Return values * **`Xchat::EAT_NONE`** - pass the event along * **`Xchat::EAT_XCHAT`** - don't let HexChat see this event * **`Xchat::EAT_PLUGIN`** - don't let other scripts and plugins see this event but xchat will still see it * **`Xchat::EAT_ALL`** - don't let anything else see this event #### Timer and fd hooks * **`Xchat::KEEP`** - keep the timer going or hook watching the handle * **`Xchat::REMOVE`** - remove the timer or hook watching the handle ### hook\_fd flags * **`Xchat::FD_READ`** - invoke the callback when the handle is ready for reading * **`Xchat::FD_WRITE`** - invoke the callback when the handle is ready for writing * **`Xchat::FD_EXCEPTION`** - invoke the callback if an exception occurs * **`Xchat::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](http://perldoc.perl.org/functions/fileno.html) * **`$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.

f 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](http://perldoc.perl.org/functions/sprintf.html)" for further details** * **`LIST` - 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] )` * **`$context` - context value as returned from `get_context`, `find_context` or one of the fields in the list of hashrefs returned by `list_get`** * **`$channel` - name of a channel you want to switch context to** * **`$server` - name of a server you want to switch context to** See `find_context` for more details on `$channel` and `$server`. Returns true on success, false on failure. ### `Xchat::get_info( $id )` * **`$id` - one of the following case sensitive values**
ID Return value Associated Command(s)
away away reason or undef if you are not away AWAY, BACK
channel current channel name SETTAB
charset character-set used in the current context CHARSET
configdir HexChat config directory encoded in UTF-8. Examples:
/home/user/.config/hexchat
C:\Users\user\Appdata\Roaming\HexChat
event_text <Event Name> text event format string for <Event name>
Example:
1
my $channel_msg_format = Xchat::get_info( "event_text Channel Message" );
host real hostname of the current server
id connection id
inputbox contents of the inputbox SETTEXT
libdirfs the system wide directory where xchat will look for plugins. this string is in the same encoding as the local file system
modes the current channels modes or undef if not known MODE
network current network name or undef, this value is taken from the Network List
nick current nick NICK
nickserv nickserv password for this network or undef, this value is taken from the Network List
server current server name
(what the server claims to be) undef if not connected
state\_cursor current inputbox cursor position in characters SETCURSOR
topic current channel topic TOPIC
version xchat version number
win_status status of the xchat window, possible values are "active", "hidden" and "normal" GUI
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 *
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 Events_** * **`LIST` - 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. Returns true on success, false on failure. ### `Xchat::send_modes( $target | \@targets, $sign, $mode, [ $modes_per_line ] )` * **`$target` - a single nick to set the mode on** * **`\@targets` - an array reference of the nicks to set the mode on** * **`$sign` - the mode sign, either '+' or '-'** * **`$mode` - the mode character such as 'o' and 'v', this can only be one character long** * **`$modes_per_line` - an optional argument maximum number of modes to send per at once, pass 0 use the current server's maximum (default)** 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 ) {
      send_modes( \@targets, $sign, $mode, 1 );
   } else {
      send_modes( $who, $sign, $mode );
   }
   return EAT_XCHAT;
});
### `Xchat::nickcmp( $nick1, $nick2 )` * **`$nick1, $nick2` - the two nicks or channel names that are to be compared** The comparsion is based on the current server. Either an [RFC1459](http://www.ietf.org/rfc/rfc1459.txt) compliant string compare or plain ascii will be using depending on the server. The comparison is case insensitive. Returns a number less than, equal to or greater than zero if `$nick1` is found respectively, to be less than, to match, or be greater than `$nick2`. ### `Xchat::get_list( $name )` * **`$name` - name of the list, one of the following: "channels", "dcc", "ignore", "notify", "users"** This function will return a list of hash references. The hash references will have different keys depend on the list. An empty list is returned if there is no such list. "channels" - list of channels, querys and their server

### `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] )` * **`$context` - context returned from `get_context`, `find_context` and `get_list`, this is the context that you want infomation about. If this is omitted, it will default to current context.** This function will return the information normally retrieved with `get_info`, except this is for the context that is passed in. The information will be returned in the form of a hash. The keys of the hash are the `$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;
});
