<h1><a name="description">DESCRIPTION</a></h1>
<p>Everytime a terminal object gets created, extension scripts specified via
the <code>perl</code> resource are loaded and associated with it.</p>
<p>Scripts are compiled in a 'use strict' and 'use utf8' environment, and
thus must be encoded as UTF-8.</p>
<p>Each script will only ever be loaded once, even in rxvtd, where
scripts will be shared (but not enabled) for all terminals.</p>
<p>
</p>
<h2><a name="prepackaged_extensions">Prepackaged Extensions</a></h2>
<p>This section describes the extensiosn delivered with this version. You can
find them in <em>/opt/rxvt/lib/urxvt/perl/</em>.</p>
<p>You can activate them like this:</p>
<pre>
  rxvt -pe &lt;extensionname&gt;</pre>
<dl>
<dt><strong><a name="item_selection">selection (enabled by default)</a></strong><br />
</dt>
<dd>
Intelligent selection. This extension tries to be more intelligent when
the user extends selections (double-click). Right now, it tries to select
urls and complete shell-quoted arguments, which is very convenient, too,
if your <em>ls</em> supports <code>--quoting-style=shell</code>.
</dd>
<dd>
<p>It also offers the following bindable event:</p>
</dd>
<dl>
<dt><strong><a name="item_rot13">rot13</a></strong><br />
</dt>
<dd>
Rot-13 the selection when activated. Used via keyboard trigger:
</dd>
<dd>
<pre>
   URxvt.keysym.C-M-r: perl:selection:rot13</pre>
</dd>
<p></p></dl>
<dt><strong><a name="item_popup">option-popup (enabled by default)</a></strong><br />
</dt>
<dd>
Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
runtime.
</dd>
<p></p>
<dt><strong>selection-popup (enabled by default)</strong><br />
</dt>
<dd>
Binds a popup menu to Ctrl-Button3 that lets you convert the selection
text into various other formats/action.
</dd>
<p></p>
<dt><strong><a name="item_searchable_2dscrollback_3chotkey_3e__28enabled_by_">searchable-scrollback&lt;hotkey&gt; (enabled by default)</a></strong><br />
</dt>
<dd>
Adds regex search functionality to the scrollback buffer, triggered
by a hotkey (default: <code>M-s</code>). When in search mode, normal terminal
input/output is suspended.
</dd>
<dd>
<p><code>/</code> starts an incremental regex search, <code>n</code> searches further, <code>p</code> or
<code>N</code> jump to the previous match, <code>G</code> jumps to the bottom and clears the
history, <code>enter</code> leaves search mode at the current position and <code>escape</code>
returns to the original position.</p>
</dd>
<p></p>
<dt><strong><a name="item_digital_2dclock">digital-clock</a></strong><br />
</dt>
<dd>
Displays a digital clock using the built-in overlay.
</dd>
<p></p>
<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br />
</dt>
<dd>
Uses per-line display filtering (<code>on_line_update</code>) to underline urls.
</dd>
<p></p>
<dt><strong><a name="item_block_2dgraphics_2dto_2dascii">block-graphics-to-ascii</a></strong><br />
</dt>
<dd>
A not very useful example of filtering all text output to the terminal,
by replacing all line-drawing characters (U+2500 .. U+259F) by a
similar-looking ascii character.
</dd>
<p></p>
<dt><strong><a name="item_example_2drefresh_2dhooks">example-refresh-hooks</a></strong><br />
</dt>
<dd>
Displays a very simple digital clock in the upper right corner of the
window. Illustrates overwriting the refresh callbacks to create your own
overlays or changes.
</dd>
<p></p></dl>
<p>
</p>
<h2><a name="general_api_considerations">General API Considerations</a></h2>
<p>All objects (such as terminals, time watchers etc.) are typical
reference-to-hash objects. The hash can be used to store anything you
like. All members starting with an underscore (such as <code>_ptr</code> or
<code>_hook</code>) are reserved for internal uses and <strong>MUST NOT</strong> be accessed or
modified).</p>
<p>When objects are destroyed on the C++ side, the perl object hashes are
emptied, so its best to store related objects such as time watchers and
the like inside the terminal object so they get destroyed as soon as the
terminal is destroyed.</p>
<p>Argument names also often indicate the type of a parameter. Here are some
hints on what they mean:</p>
<dl>
<dt><strong><a name="item__24text">$text</a></strong><br />
</dt>
<dd>
Rxvt-unicodes special way of encoding text, where one ``unicode'' character
always represents one screen cell. See <em>row_t</em> for a discussion of this format.
</dd>
<p></p>
<dt><strong><a name="item__24string">$string</a></strong><br />
</dt>
<dd>
A perl text string, with an emphasis on <em>text</em>. It can store all unicode
characters and is to be distinguished with text encoded in a specific
encoding (often locale-specific) and binary data.
</dd>
<p></p>
<dt><strong><a name="item__24octets">$octets</a></strong><br />
</dt>
<dd>
Either binary data or - more common - a text string encoded in a
locale-specific way.
</dd>
<p></p></dl>
<p>
</p>
<h2><a name="extension_objects">Extension Objects</a></h2>
<p>Very perl extension is a perl class. A separate perl object is created
for each terminal and each extension and passed as the first parameter to
hooks. So extensions can use their <code>$self</code> object without having to think
about other extensions, with the exception of methods and members that
begin with an underscore character <code>_</code>: these are reserved for internal
use.</p>
<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
<code>urxvt::term</code> class on this object.</p>
<p>It has the following methods and data members:</p>
<dl>
<dt><strong><a name="item__24urxvt_term__3d__24self_2d_3e_7bterm_7d">$urxvt_term = $self-&gt;{term}</a></strong><br />
</dt>
<dd>
Returns the <code>urxvt::term</code> object associated with this instance of the
extension. This member <em>must not</em> be changed in any way.
</dd>
<p></p>
<dt><strong><a name="item_enable">$self-&gt;enable ($hook_name =&gt; $cb, [$hook_name =&gt; $cb..])</a></strong><br />
</dt>
<dd>
Dynamically enable the given hooks (named without the <code>on_</code> prefix) for
this extension, replacing any previous hook. This is useful when you want
to overwrite time-critical hooks only temporarily.
</dd>
<p></p>
<dt><strong><a name="item_disable">$self-&gt;disable ($hook_name[, $hook_name..])</a></strong><br />
</dt>
<dd>
Dynamically disable the given hooks.
</dd>
<p></p></dl>
<p>
</p>
<h2><a name="hooks">Hooks</a></h2>
<p>The following subroutines can be declared in extension files, and will be
called whenever the relevant event happens.</p>
<p>The first argument passed to them is an extension oject as described in
the in the <code>Extension Objects</code> section.</p>
<p><strong>All</strong> of these hooks must return a boolean value. If it is true, then the
event counts as being <em>consumed</em>, and the invocation of other hooks is
skipped, and the relevant action might not be carried out by the C++ code.</p>
<p><em>When in doubt, return a false value (preferably <code>()</code>). </em>&gt;</p>
<dl>
<dt><strong><a name="item_on_init__24term">on_init $term</a></strong><br />
</dt>
<dd>
Called after a new terminal object has been initialized, but before
windows are created or the command gets run. Most methods are unsafe to
call or deliver senseless data, as terminal size and other characteristics
have not yet been determined. You can safely query and change resources,
though.
</dd>
<p></p>
<dt><strong><a name="item_on_reset__24term">on_reset $term</a></strong><br />
</dt>
<dd>
Called after the screen is ``reset'' for any reason, such as resizing or
control sequences. Here is where you can react on changes to size-related
variables.
</dd>
<p></p>
<dt><strong><a name="item_on_start__24term">on_start $term</a></strong><br />
</dt>
<dd>
Called at the very end of initialisation of a new terminal, just before
returning to the mainloop.
</dd>
<p></p>
<dt><strong><a name="item_on_sel_make__24term_2c__24eventtime">on_sel_make $term, $eventtime</a></strong><br />
</dt>
<dd>
Called whenever a selection has been made by the user, but before the
selection text is copied, so changes to the beginning, end or type of the
selection will be honored.
</dd>
<dd>
<p>Returning a true value aborts selection making by urxvt, in which case you
have to make a selection yourself by calling <a href="#item_selection_grab"><code>$term-&gt;selection_grab</code></a>.</p>
</dd>
<p></p>
<dt><strong><a name="item_on_sel_grab__24term_2c__24eventtime">on_sel_grab $term, $eventtime</a></strong><br />
</dt>
<dd>
Called whenever a selection has been copied, but before the selection is
requested from the server.  The selection text can be queried and changed
by calling <a href="#item_selection"><code>$term-&gt;selection</code></a>.
</dd>
<dd>
<p>Returning a true value aborts selection grabbing. It will still be hilighted.</p>
</dd>
<p></p>
<dt><strong><a name="item_on_sel_extend__24term">on_sel_extend $term</a></strong><br />
</dt>
<dd>
Called whenever the user tries to extend the selection (e.g. with a double
click) and is either supposed to return false (normal operation), or
should extend the selection itelf and return true to suppress the built-in
processing.
</dd>
<dd>
<p>See the <em>selection</em> example extension.</p>
</dd>
<p></p>
<dt><strong><a name="item_on_view_change__24term_2c__24offset">on_view_change $term, $offset</a></strong><br />
</dt>
<dd>
Called whenever the view offset changes, i..e the user or program
scrolls. Offset <code>0</code> means display the normal terminal, positive values
show this many lines of scrollback.
</dd>
<p></p>
<dt><strong><a name="item_on_scroll_back__24term_2c__24lines_2c__24saved">on_scroll_back $term, $lines, $saved</a></strong><br />
</dt>
<dd>
Called whenever lines scroll out of the terminal area into the scrollback
buffer. <code>$lines</code> is the number of lines scrolled out and may be larger
than the scroll back buffer or the terminal.
</dd>
<dd>
<p>It is called before lines are scrolled out (so rows 0 .. min ($lines - 1,
$nrow - 1) represent the lines to be scrolled out). <code>$saved</code> is the total
number of lines that will be in the scrollback buffer.</p>
</dd>
<p></p>
<dt><strong><a name="item_on_osc_seq__24term_2c__24string">on_osc_seq $term, $string</a></strong><br />
</dt>
<dd>
Called whenever the <strong>ESC ] 777 ; string ST</strong> command sequence (OSC =
operating system command) is processed. Cursor position and other state
information is up-to-date when this happens. For interoperability, the
string should start with the extension name and a colon, to distinguish
it from commands for other extensions, and this might be enforced in the
future.
</dd>
<dd>
<p>Be careful not ever to trust (in a security sense) the data you receive,
as its source can not easily be controleld (e-mail content, messages from
other users on the same system etc.).</p>
</dd>
<p></p>
<dt><strong><a name="item_on_add_lines__24term_2c__24string">on_add_lines $term, $string</a></strong><br />
</dt>
<dd>
Called whenever text is about to be output, with the text as argument. You
can filter/change and output the text yourself by returning a true value
and calling <a href="#item_scr_add_lines"><code>$term-&gt;scr_add_lines</code></a> yourself. Please note that this
might be very slow, however, as your hook is called for <strong>all</strong> text being
output.
</dd>
<p></p>
<dt><strong><a name="item_on_tt_write__24term_2c__24octets">on_tt_write $term, $octets</a></strong><br />
</dt>
<dd>
Called whenever some data is written to the tty/pty and can be used to
suppress or filter tty input.
</dd>
<p></p>
<dt><strong><a name="item_on_line_update__24term_2c__24row">on_line_update $term, $row</a></strong><br />
</dt>
<dd>
Called whenever a line was updated or changed. Can be used to filter
screen output (e.g. underline urls or other useless stuff). Only lines
that are being shown will be filtered, and, due to performance reasons,
not always immediately.
</dd>
<dd>
<p>The row number is always the topmost row of the line if the line spans
multiple rows.</p>
</dd>
<dd>
<p>Please note that, if you change the line, then the hook might get called
later with the already-modified line (e.g. if unrelated parts change), so
you cannot just toggle rendition bits, but only set them.</p>
</dd>
<p></p>
<dt><strong><a name="item_on_refresh_begin__24term">on_refresh_begin $term</a></strong><br />
</dt>
<dd>
Called just before the screen gets redrawn. Can be used for overlay
or similar effects by modify terminal contents in refresh_begin, and
restoring them in refresh_end. The built-in overlay and selection display
code is run after this hook, and takes precedence.
</dd>
<p></p>
<dt><strong><a name="item_on_refresh_end__24term">on_refresh_end $term</a></strong><br />
</dt>
<dd>
Called just after the screen gets redrawn. See <code>on_refresh_begin</code>.
</dd>
<p></p>
<dt><strong><a name="item_on_keyboard_command__24term_2c__24string">on_keyboard_command $term, $string</a></strong><br />
</dt>
<dd>
Called whenever the user presses a key combination that has a
<code>perl:string</code> action bound to it (see description of the <strong>keysym</strong>
resource in the <code>rxvt(1)</code> manpage).
</dd>
<p></p>
<dt><strong><a name="item_on_focus_in__24term">on_focus_in $term</a></strong><br />
</dt>
<dd>
Called whenever the window gets the keyboard focus, before rxvt-unicode
does focus in processing.
</dd>
<p></p>
<dt><strong><a name="item_on_focus_out__24term">on_focus_out $term</a></strong><br />
</dt>
<dd>
Called wheneever the window loses keyboard focus, before rxvt-unicode does
focus out processing.

</dt>
<dd>
Called whenever the corresponding X event is received for the terminal If
the hook returns true, then the even will be ignored by rxvt-unicode.
</dd>
<dd>
<p>The event is a hash with most values as named by Xlib (see the XEvent
manpage), with the additional members <code>row</code> and <code>col</code>, which are the row
and column under the mouse cursor.</p>

<h2><a name="the_urxvt__anyevent_class">The <code>urxvt::anyevent</code> Class</a></h2>
<p>The sole purpose of this class is to deliver an interface to the
<code>AnyEvent</code> module - any module using it will work inside urxvt without
further work. The only exception is that you cannot wait on condition
variables, but non-blocking condvar use is ok. What this means is that you
cannot use blocking APIs, but the non-blocking variant should work.</p>

<dt><strong><a name="item_strwidth">$cellwidth = $term-&gt;strwidth ($string)</a></strong><br />
</dt>
<dd>
Returns the number of screen-cells this string would need. Correctly
accounts for wide and combining characters.
</dd>
<p></p>
<dt><strong><a name="item_locale_encode">$octets = $term-&gt;locale_encode ($string)</a></strong><br />

</dt>
<dd>
Write the given text string to the screen, as if output by the application
running inside the terminal. It may not contain command sequences (escape
codes), but is free to use line feeds, carriage returns and tabs. The
string is a normal text string, not in locale-dependent encoding.
</dd>
<dd>
<p>Normally its not a good idea to use this function, as programs might be
confused by changes in cursor position or scrolling. Its useful inside a

<dt><strong><a name="item_cmd_parse">$term-&gt;cmd_parse ($octets)</a></strong><br />
</dt>
<dd>
Similar to <a href="#item_scr_add_lines"><code>scr_add_lines</code></a>, but the argument must be in the

</dd>
<p></p>
<dt><strong><a name="item_tt_write">$term-&gt;tt_write ($octets)</a></strong><br />
</dt>
<dd>
Write the octets given in <code>$data</code> to the tty (i.e. as program input). To
pass characters instead of octets, you should convert your strings first
to the locale-specific encoding using <a href="#item_locale_encode"><code>$term-&gt;locale_encode</code></a>.

<dt><strong><a name="item_view_start">$view_start = $term-&gt;view_start ([$newvalue])</a></strong><br />
</dt>
<dd>
Returns the negative row number of the topmost line. Minimum value is

<p></p>
<dt><strong><a name="item_want_refresh">$term-&gt;want_refresh</a></strong><br />
</dt>
<dd>
Requests a screen refresh. At the next opportunity, rxvt-unicode will
compare the on-screen display with its stored representation. If they

</dt>
<dd>
Returns the text of the entire row with number <code>$row_number</code>. Row <code>0</code>

terminal line. The scrollback buffer starts at line <code>-1</code> and extends to
line <a href="#item_nsaved"><code>-$term-&gt;nsaved</code></a>. Nothing will be returned if a nonexistent line
is requested.
</dd>
<dd>
<p>If <code>$new_text</code> is specified, it will replace characters in the current
line, starting at column <code>$start_col</code> (default <code>0</code>), which is useful
to replace only parts of a line. The font index in the rendition will
automatically be updated.</p>
</dd>
<dd>
<p><a href="#item__24text"><code>$text</code></a> is in a special encoding: tabs and wide characters that use more
