<p>
</p>
<h2><a name="introduction" />Introduction</h2>
<p>This is the new Perl interface for X-Chat 2.  However, due to changes in
xchat's plugin code you will need xchat 2.0.8 or above to load this.  Scripts
written using the old interface will continue to work. If there are any
problems, questions, comments or suggestions please email them to the address
on the bottom of this page.</p>

<p>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-&gt;Advanced-&gt;Text Events
hook_timer can be used to create a new timer</p>
<ul>
<li><strong><code>$message</code>       -  server message to hook such as PRIVMSG</strong>
</li>
<li><strong><code>$command</code>       -  command to intercept, without the leading /</strong>
</li>
<li><strong><code>$event</code>      -  one of the events listed in Settings-&gt;Advanced-&gt;Text Events</strong>
</li>
<li><strong><code>$timeout</code>       -  timeout in milliseconds</strong>
</li>
<li><strong><code>$handle</code>     - the I/O handle you want to monitor with hook_fd. This must be something that has a fileno. See perldoc -f fileno or <a href="http://perldoc.perl.org/functions/fileno.html">fileno</a></strong>
</li>
<li><strong><code>$callback</code>   -  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.</strong>

<p>The first argument can either be a string or an array reference of strings.
Either or both of <code>$channel</code> and <code>$server</code> can be undef.</p>
<p>If called as <code>Xchat::command( $command )</code>, it will always return true.
If called with either the channel or the channel and the server

the same as <code>Xchat::find_context( $channel, undef )</code>.</p>
<p>If <code>$server</code> is undef, find any channel named $channel.

<h3><a name="xchat_user_info" /><code>Xchat::user_info( [$nick] )</code></h3>
<ul>
<li><strong><code>$nick</code> -  the nick to look for, if this is not given your own nick will be
            used as default</strong>
</li>
</ul>
<p>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 <a href="#xchat_get_list">get_list</a>.
If <code>$nick</code> is found a hash reference containing the same keys as those in the
&quot;users&quot; list of <a href="#xchat_get_list">get_list</a> is returned otherwise undef is returned.
Since it relies on <a href="#xchat_get_list">get_list</a> this function can only be used in a
channel context.</p>
<p>
</p>
<h3><a name="xchat_context_info" /><code>Xchat::context_info( [$context] )</code></h3>
<ul>
<li><strong><code>$context</code> -  context returned from <a href="#xchat_get_context">get_context</a>, <a href="#xchat_find_context">find_context</a> and <a href="#xchat_get_list">get_list</a>, this is the context that you want infomation about. If this is omitted, it will default to current context.</strong>
</li>
</ul>
<p>This function will return the information normally retrieved with <a href="#xchat_get_info">get_info</a>, except this is for the context that is passed in. The information will be returned in the form of a hash. The keys of the hash are the <code>$id</code> you would normally supply to <a href="#xchat_get_info">get_info</a> as well as all the keys that are valid for the items in the &quot;channels&quot; list from <a href="#xchat_get_list">get_list</a>. Use of this function is more efficient than calling get_list( &quot;channels&quot; ) and searching through the result.</p>

<h3><a name="xchat_strip_code" /><code>Xchat::strip_code( $string )</code></h3>
<ul>
<li><strong><code>$string</code>  -  string to remove codes from</strong>
</li>
</ul>
<p>This function will remove bold, color, beep, reset, reverse and underline codes from <code>$string</code>. It will also remove ANSI escape codes which might get used by certain terminal based clients. If it is called in void context <code>$string</code> will be modified otherwise a modified copy of <code>$string</code> is returned.</p>
