		26	Prepackaged Extensions
		27	This section describes the extensiosn delivered with this version. You
		28	can find them in /opt/rxvt/lib/urxvt/perl/.
		29
		30	You can activate them like this:
		31
		32	rxvt -pe <extensionname>
		33
		34	selection (enabled by default)
		35	Intelligent selection. This extension tries to be more intelligent
		36	when the user extends selections (double-click). Right now, it tries
		37	to select urls and complete shell-quoted arguments, which is very
		38	convenient, too, if your ls supports "--quoting-style=shell".
		39
		40	It also offers the following bindable event:
		41
		42	rot13
		43	Rot-13 the selection when activated. Used via keyboard trigger:
		44
		45	URxvt.keysym.C-M-r: perl:selection:rot13
		46
		47	option-popup (enabled by default)
		48	Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
		49	options at runtime.
		50
		51	selection-popup (enabled by default)
		52	Binds a popup menu to Ctrl-Button3 that lets you convert the
		53	selection text into various other formats/action.
		54
		55	digital-clock
		56	Displays a digital clock using the built-in overlay.
		57
		58	mark-urls
		59	Uses per-line display filtering ("on_line_update") to underline
		60	urls.
		61
		62	block-graphics-to-ascii
		63	A not very useful example of filtering all text output to the
		64	terminal, by replacing all line-drawing characters (U+2500 ..
		65	U+259F) by a similar-looking ascii character.
		66
		67	example-refresh-hooks
		68	Displays a very simple digital clock in the upper right corner of
		69	the window. Illustrates overwriting the refresh callbacks to create
		70	your own overlays or changes.

36		83
		84	Argument names also often indicate the type of a parameter. Here are
		85	some hints on what they mean:
		86
		87	$text
		88	Rxvt-unicodes special way of encoding text, where one "unicode"
		89	character always represents one screen cell. See row_t for a
		90	discussion of this format.
		91
		92	$string
		93	A perl text string, with an emphasis on text. It can store all
		94	unicode characters and is to be distinguished with text encoded in a
		95	specific encoding (often locale-specific) and binary data.
		96
		97	$octets
		98	Either binary data or - more common - a text string encoded in a
		99	locale-specific way.
		100

		104
		105	The first argument passed to them is an object private to each terminal
		106	and extension package. You can call all "urxvt::term" methods on it, but
		107	its not a real "urxvt::term" object. Instead, the real "urxvt::term"
		108	object that is shared between all packages is stored in the "term"
		109	member. It is, however, blessed intot he package of the extension
		110	script, so for all practical purposes you can treat an extension script
		111	as a class.

100	on_tty_activity $term NYI	175	on_osc_seq $term, $string
101	Called whenever the program(s) running in the urxvt window send	176	Called whenever the ESC ] 777 ; string ST command sequence (OSC =
102	output.	177	operating system command) is processed. Cursor position and other
		178	state information is up-to-date when this happens. For
		179	interoperability, the string should start with the extension name
		180	and a colon, to distinguish it from commands for other extensions,
		181	and this might be enforced in the future.
		182
		183	Be careful not ever to trust (in a security sense) the data you
		184	receive, as its source can not easily be controleld (e-mail content,
		185	messages from other users on the same system etc.).
		186
		187	on_add_lines $term, $string
		188	Called whenever text is about to be output, with the text as
		189	argument. You can filter/change and output the text yourself by
		190	returning a true value and calling "$term->scr_add_lines" yourself.
		191	Please note that this might be very slow, however, as your hook is
		192	called for all text being output.
		193
		194	on_line_update $term, $row
		195	Called whenever a line was updated or changed. Can be used to filter
		196	screen output (e.g. underline urls or other useless stuff). Only
		197	lines that are being shown will be filtered, and, due to performance
		198	reasons, not always immediately.
		199
		200	The row number is always the topmost row of the line if the line
		201	spans multiple rows.
		202
		203	Please note that, if you change the line, then the hook might get
		204	called later with the already-modified line (e.g. if unrelated parts
		205	change), so you cannot just toggle rendition bits, but only set
		206	them.

112		216
		217	on_keyboard_command $term, $string
		218	Called whenever the user presses a key combination that has a
		219	"perl:string" action bound to it (see description of the keysym
		220	resource in the rxvt(1) manpage).
		221
		222	on_focus_in $term
		223	Called whenever the window gets the keyboard focus, before
		224	rxvt-unicode does focus in processing.
		225
		226	on_focus_out $term
		227	Called wheneever the window loses keyboard focus, before

		237	Called whenever the corresponding X event is received for the
		238	terminal If the hook returns true, then the even will be ignored by
		239	rxvt-unicode.
		240
		241	The event is a hash with most values as named by Xlib (see the
		242	XEvent manpage), with the additional members "row" and "col", which
		243	are the row and column under the mouse cursor.
		244

		259	message) if the new instance couldn't be created. Returns "undef" if
		260	the new instance didn't initialise perl, and the terminal object

		284	Various constants for use in X calls and event processing.
		285
		286	RENDITION
		287	Rendition bitsets contain information about colour, font, font styles
		288	and similar information for each screen cell.
		289
		290	The following "macros" deal with changes in rendition sets. You should
		291	never just create a bitset, you should always modify an existing one, as
		292	they contain important information required for correct operation of
		293	rxvt-unicode.
		294
		295	$rend = urxvt::DEFAULT_RSTYLE
		296	Returns the default rendition, as used when the terminal is starting
		297	up or being reset. Useful as a base to start when creating
		298	renditions.
		299
		300	$rend = urxvt::OVERLAY_RSTYLE
		301	Return the rendition mask used for overlays by default.
		302
		303	$rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
		304	Return the bit that enabled bold, italic, blink, reverse-video and
		305	underline, respectively. To enable such a style, just logically OR
		306	it into the bitset.
		307
		308	$foreground = urxvt::GET_BASEFG $rend
		309	$background = urxvt::GET_BASEBG $rend
		310	Return the foreground/background colour index, respectively.
		311
		312	$rend = urxvt::SET_FGCOLOR ($rend, $new_colour)
		313	$rend = urxvt::SET_BGCOLOR ($rend, $new_colour)
		314	Replace the foreground/background colour in the rendition mask with
		315	the specified one.
		316
		317	$value = urxvt::GET_CUSTOM ($rend)
		318	Return the "custom" value: Every rendition has 5 bits for use by
		319	extensions. They can be set and changed as you like and are
		320	initially zero.
		321
		322	$rend = urxvt::SET_CUSTOM ($rend, $new_value)
		323	Change the custom value.
		324
		325	The "urxvt::anyevent" Class
		326	The sole purpose of this class is to deliver an interface to the
		327	"AnyEvent" module - any module using it will work inside urxvt without
		328	further work. The only exception is that you cannot wait on condition
		329	variables, but non-blocking condvar use is ok. What this means is that
		330	you cannot use blocking APIs, but the non-blocking variant should work.
		331

		335
		336	$isset = $term->option ($optval[, $set])
		337	Returns true if the option specified by $optval is enabled, and
		338	optionally change it. All option values are stored by name in the
		339	hash %urxvt::OPTION. Options not enabled in this binary are not in
		340	the hash.

		438	$overlay->hide
		439	If visible, hide the overlay, but do not destroy it.

		441	$overlay->show
		442	If hidden, display the overlay again.
		443
		444	$popup = $term->popup ($event)
		445	Creates a new "urxvt::popup" object that implements a popup menu.

		459
		460	$term->scr_add_lines ($string)
		461	Write the given text string to the screen, as if output by the
		462	application running inside the terminal. It may not contain command
		463	sequences (escape codes), but is free to use line feeds, carriage
		464	returns and tabs. The string is a normal text string, not in
		465	locale-dependent encoding.
		466
		467	Normally its not a good idea to use this function, as programs might
		468	be confused by changes in cursor position or scrolling. Its useful
		469	inside a "on_add_lines" hook, though.
		470
		471	$term->cmd_parse ($octets)
		472	Similar to "scr_add_lines", but the argument must be in the

		501
		502	$modifiermask = $term->ModLevel3Mask
		503	$modifiermask = $term->ModMetaMask
		504	$modifiermask = $term->ModNumLockMask
		505	Return the modifier masks corresponding to the "ISO Level 3 Shift"
		506	(often AltGr), the meta key (often Alt) and the num lock key, if
		507	applicable.
		508
		509	$view_start = $term->view_start ([$newvalue])
		510	Returns the negative row number of the topmost line. Minimum value
		511	is 0, which displays the normal terminal contents. Larger values
		512	scroll this many lines into the scrollback buffer.
		513
		514	$term->want_refresh
		515	Requests a screen refresh. At the next opportunity, rxvt-unicode
		516	will compare the on-screen display with its stored representation.
		517	If they differ, it redraws the differences.
		518
		519	Used after changing terminal contents to display them.
		520
		521	$text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		522	Returns the text of the entire row with number $row_number. Row 0 is
		523	the topmost terminal line, row "$term->$ncol-1" is the bottommost
		524	terminal line. The scrollback buffer starts at line -1 and extends
		525	to line "-$term->nsaved". Nothing will be returned if a nonexistent
		526	line is requested.
		527
		528	If $new_text is specified, it will replace characters in the current
		529	line, starting at column $start_col (default 0), which is useful to
		530	replace only parts of a line. The font index in the rendition will
		531	automatically be updated.
		532
		533	$text is in a special encoding: tabs and wide characters that use
		534	more than one cell when displayed are padded with urxvt::NOCHAR
		535	characters ("chr 65535"). Characters with combining characters and
		536	other characters that do not fit into the normal tetx encoding will
		537	be replaced with characters in the private use area.
		538
		539	You have to obey this encoding when changing text. The advantage is
		540	that "substr" and similar functions work on screen cells and not on
		541	characters.
		542
		543	The methods "$term->special_encode" and "$term->special_decode" can
		544	be used to convert normal strings into this encoding and vice versa.
		545
		546	$rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		547	Like "$term->ROW_t", but returns an arrayref with rendition bitsets.
		548	Rendition bitsets contain information about colour, font, font
		549	styles and similar information. See also "$term->ROW_t".
		550
		551	When setting rendition, the font mask will be ignored.
		552
		553	See the section on RENDITION, above.
		554
		555	$length = $term->ROW_l ($row_number[, $new_length])
		556	Returns the number of screen cells that are in use ("the line
		557	length"). Unlike the urxvt core, this returns "$term->ncol" if the
		558	line is joined with the following one.
		559
		560	$bool = $term->is_longer ($row_number)
		561	Returns true if the row is part of a multiple-row logical "line"
		562	(i.e. joined with the following row), which means all characters are
		563	in use and it is continued on the next row (and possibly a
		564	continuation of the previous row(s)).
		565
		566	$line = $term->line ($row_number)
		567	Create and return a new "urxvt::line" object that stores information
		568	about the logical line that row $row_number is part of. It supports
		569	the following methods:
		570
		571	$text = $line->t ([$new_text])
		572	Returns or replaces the full text of the line, similar to
		573	"ROW_t"
		574
		575	$rend = $line->r ([$new_rend])
		576	Returns or replaces the full rendition array of the line,
		577	similar to "ROW_r"
		578
		579	$length = $line->l
		580	Returns the length of the line in cells, similar to "ROW_l".
		581
		582	$rownum = $line->beg
		583	$rownum = $line->end
		584	Return the row number of the first/last row of the line,
		585	respectively.
		586
		587	$offset = $line->offset_of ($row, $col)
		588	Returns the character offset of the given row\|col pair within
		589	the logical line.
		590
		591	($row, $col) = $line->coord_of ($offset)
		592	Translates a string offset into terminal coordinates again.
		593
		594	$text = $term->special_encode $string
		595	Converts a perl string into the special encoding used by
		596	rxvt-unicode, where one character corresponds to one screen cell.
		597	See "$term->ROW_t" for details.
		598
		599	$string = $term->special_decode $text
		600	Converts rxvt-unicodes text reprsentation into a perl string. See
		601	"$term->ROW_t" for details.
		602
		603	$success = $term->grab_button ($button, $modifiermask)
		604	Registers a synchronous button grab. See XGrabButton.
		605
		606	$success = $term->grab ($eventtime[, $sync])
		607	Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
		608	synchronous ($sync is true). Also remembers the grab timestampe.
		609
		610	$term->allow_events_async
		611	Calls XAllowEvents with AsyncBoth for the most recent grab.
		612
		613	$term->allow_events_sync
		614	Calls XAllowEvents with SyncBoth for the most recent grab.
		615
		616	$term->allow_events_replay
		617	Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for
		618	the most recent grab.
		619
		620	$term->ungrab
		621	Calls XUngrab for the most recent grab. Is called automatically on
		622	evaluation errors, as it is better to lose the grab in the error
		623	case as the session.
