68<p>Everytime a terminal object gets created, extension scripts specified via
69the <code>perl</code> resource are loaded and associated with it.</p>
70<p>Scripts are compiled in a 'use strict' and 'use utf8' environment, and

72<p>Each script will only ever be loaded once, even in rxvtd, where

76<h2><a name="prepackaged_extensions">Prepackaged Extensions</a></h2>
77<p>This section describes the extensiosn delivered with this version. You can
78find them in <em>/opt/rxvt/lib/urxvt/perl/</em>.</p>
79<p>You can activate them like this:</p>
80<pre>
81 rxvt -pe &lt;extensionname&gt;</pre>
82<dl>
83<dt><strong><a name="item_selection">selection (enabled by default)</a></strong><br />
84</dt>
85<dd>
86Intelligent selection. This extension tries to be more intelligent when
87the user extends selections (double-click). Right now, it tries to select
88urls and complete shell-quoted arguments, which is very convenient, too,
89if your <em>ls</em> supports <code>--quoting-style=shell</code>.
90</dd>
91<dd>
92<p>It also offers the following bindable event:</p>

128by replacing all line-drawing characters (U+2500 .. U+259F) by a

142<h2><a name="general_api_considerations">General API Considerations</a></h2>
143<p>All objects (such as terminals, time watchers etc.) are typical
144reference-to-hash objects. The hash can be used to store anything you
145like. All members starting with an underscore (such as <code>_ptr</code> or
146<code>_hook</code>) are reserved for internal uses and <strong>MUST NOT</strong> be accessed or
147modified).</p>
148<p>When objects are destroyed on the C++ side, the perl object hashes are
149emptied, so its best to store related objects such as time watchers and
150the like inside the terminal object so they get destroyed as soon as the
151terminal is destroyed.</p>
152<p>Argument names also often indicate the type of a parameter. Here are some
153hints on what they mean:</p>
154<dl>
155<dt><strong><a name="item__24text">$text</a></strong><br />
156</dt>
157<dd>
158Rxvt-unicodes special way of encoding text, where one ``unicode'' character
159always represents one screen cell. See <em>row_t</em> for a discussion of this format.
160</dd>
161<p></p>
162<dt><strong><a name="item__24string">$string</a></strong><br />
163</dt>
164<dd>
165A perl text string, with an emphasis on <em>text</em>. It can store all unicode
166characters and is to be distinguished with text encoded in a specific
167encoding (often locale-specific) and binary data.
168</dd>
169<p></p>
170<dt><strong><a name="item__24octets">$octets</a></strong><br />
171</dt>

283Called whenever the <strong>ESC ] 777 ; string ST</strong> command sequence (OSC =
284operating system command) is processed. Cursor position and other state
285information is up-to-date when this happens. For interoperability, the
286string should start with the extension name and a colon, to distinguish
287it from commands for other extensions, and this might be enforced in the
288future.

300can filter/change and output the text yourself by returning a true value
301and calling <a href="#item_scr_add_lines"><code>$term-&gt;scr_add_lines</code></a> yourself. Please note that this

309Called whenever a line was updated or changed. Can be used to filter
310screen output (e.g. underline urls or other useless stuff). Only lines
311that are being shown will be filtered, and, due to performance reasons,
312not always immediately.

319<p>Please note that, if you change the line, then the hook might get called
320later with the already-modified line (e.g. if unrelated parts change), so
