		72	Argument names also often indicate the type of a parameter. Here are some
		73	hints on what they mean:
		74
		75	=over 4
		76
		77	=item $text
		78
		79	Rxvt-unicode's special way of encoding text, where one "unicode" character
		80	always represents one screen cell. See L<ROW_t> for a discussion of this format.
		81
		82	=item $string
		83
		84	A perl text string, with an emphasis on I<text>. It can store all unicode
		85	characters and is to be distinguished with text encoded in a specific
		86	encoding (often locale-specific) and binary data.
		87
		88	=item $octets
		89
		90	Either binary data or - more common - a text string encoded in a
		91	locale-specific way.
		92
		93	=item $keysym
		94
		95	an integer that is a valid X11 keysym code. You can convert a string
		96	into a keysym and viceversa by using C<XStringToKeysym> and
		97	C<XKeysymToString>.
		98
		99	=back
		100
		101	=head2 Extension Objects
		102
		103	Every perl extension is a perl class. A separate perl object is created
		104	for each terminal, and each terminal has its own set of extension objects,
		105	which are passed as the first parameter to hooks. So extensions can use
		106	their C<$self> object without having to think about clashes with other
		107	extensions or other terminals, with the exception of methods and members
		108	that begin with an underscore character C<_>: these are reserved for
		109	internal use.
		110
		111	Although it isn't a C<urxvt::term> object, you can call all methods of the
		112	C<urxvt::term> class on this object.
		113
		114	Additional methods only supported for extension objects are described in
		115	the C<urxvt::extension> section below.
		116
		117	=head2 META comments
		118
		119	Rxvt-unicode recognizes special meta comments in extensions that define
		120	different types of metadata. These comments are scanned whenever a
		121	terminal is created and are typically used to autoload extensions when
		122	their resources or command line parameters are used.
		123
		124	Currently, it recognises only one such comment:
		125
		126	=over 4
		127
		128	=item #:META:RESOURCE:name:type:desc
		129
		130	The RESOURCE comment defines a resource used by the extension, where
		131	C<name> is the resource name, C<type> is the resource type, C<boolean>
		132	or C<string>, and C<desc> is the resource description.
		133
		134	The extension will be autoloaded when this resource is specified or used
		135	as a command line parameter.

171	=item on_tty_activity $term *NYI*	233	=item on_osc_seq $term, $op, $args, $resp
172		234
173	Called whenever the program(s) running in the urxvt window send output.	235	Called on every OSC sequence and can be used to suppress it or modify its
		236	behaviour. The default should be to return an empty list. A true value
		237	suppresses execution of the request completely. Make sure you don't get
		238	confused by recursive invocations when you output an OSC sequence within
		239	this callback.
		240
		241	C<on_osc_seq_perl> should be used for new behaviour.
		242
		243	=item on_osc_seq_perl $term, $args, $resp
		244
		245	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		246	operating system command) is processed. Cursor position and other state
		247	information is up-to-date when this happens. For interoperability, the
		248	string should start with the extension name (sans -osc) and a semicolon,
		249	to distinguish it from commands for other extensions, and this might be
		250	enforced in the future.
		251
		252	For example, C<overlay-osc> uses this:
		253
		254	sub on_osc_seq_perl {
		255	my ($self, $osc, $resp) = @_;
		256
		257	return unless $osc =~ s/^overlay;//;
		258
		259	... process remaining $osc string
		260	}
		261
		262	Be careful not ever to trust (in a security sense) the data you receive,
		263	as its source can not easily be controlled (e-mail content, messages from
		264	other users on the same system etc.).
		265
		266	For responses, C<$resp> contains the end-of-args separator used by the
		267	sender.
		268
		269	=item on_add_lines $term, $string
		270
		271	Called whenever text is about to be output, with the text as argument. You
		272	can filter/change and output the text yourself by returning a true value
		273	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		274	might be very slow, however, as your hook is called for B<all> text being
		275	output.
		276
		277	=item on_tt_write $term, $octets
		278
		279	Called whenever some data is written to the tty/pty and can be used to
		280	suppress or filter tty input.
		281
		282	=item on_tt_paste $term, $octets
		283
		284	Called whenever text is about to be pasted, with the text as argument. You
		285	can filter/change and paste the text yourself by returning a true value
		286	and calling C<< $term->tt_paste >> yourself. C<$octets> is
		287	locale-encoded.
		288
		289	=item on_line_update $term, $row
		290
		291	Called whenever a line was updated or changed. Can be used to filter
		292	screen output (e.g. underline urls or other useless stuff). Only lines
		293	that are being shown will be filtered, and, due to performance reasons,
		294	not always immediately.
		295
		296	The row number is always the topmost row of the line if the line spans
		297	multiple rows.
		298
		299	Please note that, if you change the line, then the hook might get called
		300	later with the already-modified line (e.g. if unrelated parts change), so
		301	you cannot just toggle rendition bits, but only set them.
174		302

185		313
		314	=item on_action $term, $string
		315
		316	Called whenever an action is invoked for the corresponding extension
		317	(e.g. via a C<extension:string> builtin action bound to a key, see
		318	description of the B<keysym> resource in the urxvt(1) manpage). The
		319	event is simply the action string. Note that an action event is always
		320	associated to a single extension.

		328	The event is simply the action string. This interface is going away in

		330
		331	=item on_resize_all_windows $term, $new_width, $new_height
		332
		333	Called just after the new window size has been calculated, but before
		334	windows are actually being resized or hints are being set. If this hook
		335	returns a true value, setting of the window hints is being skipped.
		336
		337	=item on_x_event $term, $event
		338
		339	Called on every X event received on the vt window (and possibly other
		340	windows). Should only be used as a last resort. Most event structure
		341	members are not passed.
		342
		343	=item on_root_event $term, $event
		344
		345	Like C<on_x_event>, but is called for events on the root window.
		346
		347	=item on_focus_in $term
		348
		349	Called whenever the window gets the keyboard focus, before rxvt-unicode
		350	does focus in processing.
		351
		352	=item on_focus_out $term
		353
		354	Called whenever the window loses keyboard focus, before rxvt-unicode does

		371	=item on_map_notify $term, $event
		372
		373	=item on_unmap_notify $term, $event
		374
		375	Called whenever the corresponding X event is received for the terminal. If
		376	the hook returns true, then the event will be ignored by rxvt-unicode.
		377
		378	The event is a hash with most values as named by Xlib (see the XEvent
		379	manpage), with the additional members C<row> and C<col>, which are the
		380	(real, not screen-based) row and column under the mouse cursor.
		381
		382	C<on_key_press> additionally receives the string rxvt-unicode would

		393

		1341
		1342	Extensions that define extra resources also need to call this method
		1343	to access their values.
		1344
		1345	If the method is called on an extension object (basically, from an
		1346	extension), then the special prefix C<%.> will be replaced by the name of
		1347	the extension and a dot, and the lone string C<%> will be replaced by the
		1348	extension name itself. This makes it possible to code extensions so you
		1349	can rename them and get a new set of resources without having to change
		1350	the actual code.
		1351
		1352	This method should only be called during the C<on_start> hook, as there is
		1353	only one resource database per display, and later invocations might return

		1381
		1382	To add default bindings for actions, an extension should call C<<

		1384	in the C<init> hook allows users to override or remove the binding
