27	terminals created with that specific option value.	27	This section describes the extensions delivered with this release. You
		28	can find them in /opt/rxvt/lib/urxvt/perl/.
28		29
		30	You can activate them like this:
		31
		32	rxvt -pe <extensionname>
		33
		34	Or by adding them to the resource for extensions loaded by default:
		35
		36	URxvt.perl-ext-common: default,automove-background,selection-autotransform
		37
		38	selection (enabled by default)
		39	(More) intelligent selection. This extension tries to be more
		40	intelligent when the user extends selections (double-click and
		41	further clicks). Right now, it tries to select words, urls and
		42	complete shell-quoted arguments, which is very convenient, too, if
		43	your ls supports "--quoting-style=shell".
		44
		45	A double-click usually selects the word under the cursor, further
		46	clicks will enlarge the selection.
		47
		48	The selection works by trying to match a number of regexes and
		49	displaying them in increasing order of length. You can add your own
		50	regexes by specifying resources of the form:
		51
		52	URxvt.selection.pattern-0: perl-regex
		53	URxvt.selection.pattern-1: perl-regex
		54	...
		55
		56	The index number (0, 1...) must not have any holes, and each regex
		57	must contain at least one pair of capturing parentheses, which will
		58	be used for the match. For example, the followign adds a regex that
		59	matches everything between two vertical bars:
		60
		61	URxvt.selection.pattern-0: \\\|([^\|]+)\\\|
		62
		63	Another example: Programs I use often output "absolute path: " at
		64	the beginning of a line when they process multiple files. The
		65	following pattern matches the filename (note, there is a single
		66	space at the very end):
		67
		68	URxvt.selection.pattern-0: ^(/[^:]+):\
		69
		70	You can look at the source of the selection extension to see more
		71	interesting uses, such as parsing a line from beginning to end.
		72
		73	This extension also offers following bindable keyboard commands:
		74
		75	rot13
		76	Rot-13 the selection when activated. Used via keyboard trigger:
		77
		78	URxvt.keysym.C-M-r: perl:selection:rot13
		79
		80	option-popup (enabled by default)
		81	Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
		82	options at runtime.
		83
		84	selection-popup (enabled by default)
		85	Binds a popup menu to Ctrl-Button3 that lets you convert the
		86	selection text into various other formats/action (such as uri
		87	unescaping, perl evaluation, web-browser starting etc.), depending
		88	on content.
		89
		90	Other extensions can extend this popup menu by pushing a code
		91	reference onto "@{ $term-"{selection_popup_hook} }>, that is called
		92	whenever the popup is displayed.
		93
		94	It's sole argument is the popup menu, which can be modified. The
		95	selection is in $_, which can be used to decide wether to add
		96	something or not. It should either return nothing or a string and a
		97	code reference. The string will be used as button text and the code
		98	reference will be called when the button gets activated and should
		99	transform $_.
		100
		101	The following will add an entry "a to b" that transforms all "a"s in
		102	the selection to "b"s, but only if the selection currently contains
		103	any "a"s:
		104
		105	push @{ $self->{term}{selection_popup_hook} }, sub {
		106	/a/ ? ("a to be" => sub { s/a/b/g }
		107	: ()
		108	};
		109
		110	searchable-scrollback<hotkey> (enabled by default)
		111	Adds regex search functionality to the scrollback buffer, triggered
		112	by a hotkey (default: "M-s"). While in search mode, normal terminal
		113	input/output is suspended and a regex is displayed at the bottom of
		114	the screen.
		115
		116	Inputting characters appends them to the regex and continues
		117	incremental search. "BackSpace" removes a character from the regex,
		118	"Up" and "Down" search upwards/downwards in the scrollback buffer,
		119	"End" jumps to the bottom. "Escape" leaves search mode and returns
		120	to the point where search was started, while "Enter" or "Return"
		121	stay at the current position and additionally stores the first match
		122	in the current line into the primary selection.
		123
		124	readline (enabled by default)
		125	A support package that tries to make editing with readline easier.
		126	At the moment, it reacts to clicking with the left mouse button by
		127	trying to move the text cursor to this position. It does so by
		128	generating as many cursor-left or cursor-right keypresses as
		129	required (the this only works for programs that correctly support
		130	wide characters).
		131
		132	To avoid too many false positives, this is only done when:
		133
		134	- the tty is in ICANON state.
		135	- the text cursor is visible.
		136	- the primary screen is currently being displayed.
		137	- the mouse is on the same (multi-row-) line as the text cursor.
		138
		139	The normal selection mechanism isn't disabled, so quick successive
		140	clicks might interfere with selection creation in harmless ways.
		141
		142	selection-autotransform
		143	This selection allows you to do automatic transforms on a selection
		144	whenever a selection is made.
		145
		146	It works by specifying perl snippets (most useful is a single "s///"
		147	operator) that modify $_ as resources:
		148
		149	URxvt.selection-autotransform.0: transform
		150	URxvt.selection-autotransform.1: transform
		151	...
		152
		153	For example, the following will transform selections of the form
		154	"filename:number", often seen in compiler messages, into "vi
		155	+$filename $word":
		156
		157	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		158
		159	And this example matches the same,but replaces it with vi-commands
		160	you can paste directly into your (vi :) editor:
		161
		162	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		163
		164	Of course, this can be modified to suit your needs and your editor
		165	:)
		166
		167	To expand the example above to typical perl error messages ("XXX at
		168	FILENAME line YYY."), you need a slightly more elaborate solution:
		169
		170	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		171	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		172
		173	The first line tells the selection code to treat the unchanging part
		174	of every error message as a selection pattern, and the second line
		175	transforms the message into vi commands to load the file.
		176
		177	tabbed
		178	This transforms the terminal into a tabbar with additional
		179	terminals, that is, it implements what is commonly refered to as
		180	"tabbed terminal". The topmost line displays a "[NEW]" button,
		181	which, when clicked, will add a new tab, followed by one button per
		182	tab.
		183
		184	Clicking a button will activate that tab. Pressing Shift-Left and
		185	Shift-Right will switch to the tab left or right of the current one,
		186	while Shift-Down creates a new tab.
		187
		188	mark-urls
		189	Uses per-line display filtering ("on_line_update") to underline urls
		190	and make them clickable. When middle-clicked, the program specified
		191	in the resource "urlLauncher" (default "x-www-browser") will be
		192	started with the URL as first argument.
		193
		194	xim-onthespot
		195	This (experimental) perl extension implements OnTheSpot editing. It
		196	does not work perfectly, and some input methods don't seem to work
		197	well with OnTheSpot editing in general, but it seems to work at
		198	leats for SCIM and kinput2.
		199
		200	You enable it by specifying this extension and a preedit style of
		201	"OnTheSpot", i.e.:
		202
		203	rxvt -pt OnTheSpot -pe xim-onthespot
		204
		205	automove-background
		206	This is basically a one-line extension that dynamically changes the
		207	background pixmap offset to the window position, in effect creating
		208	the same effect as pseudo transparency with a custom pixmap. No
		209	scaling is supported in this mode. Exmaple:
		210
		211	rxvt -pixmap background.xpm -pe automove-background
		212
		213	block-graphics-to-ascii
		214	A not very useful example of filtering all text output to the
		215	terminal, by replacing all line-drawing characters (U+2500 ..
		216	U+259F) by a similar-looking ascii character.
		217
		218	digital-clock
		219	Displays a digital clock using the built-in overlay.
		220
		221	example-refresh-hooks
		222	Displays a very simple digital clock in the upper right corner of
		223	the window. Illustrates overwriting the refresh callbacks to create
		224	your own overlays or changes.
		225
		226	selection-pastebin
		227	This is a little rarely useful extension that Uploads the selection
		228	as textfile to a remote site (or does other things). (The
		229	implementation is not currently secure for use in a multiuser
		230	environment as it writes to /tmp directly.).
		231
		232	It listens to the "selection-pastebin:remote-pastebin" keyboard
		233	command, i.e.
		234
		235	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		236
		237	Pressing this combination runs a command with "%" replaced by the
		238	name of the textfile. This command can be set via a resource:
		239
		240	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		241
		242	And the default is likely not useful to anybody but the few people
		243	around here :)
		244
		245	The name of the textfile is the hex encoded md5 sum of the
		246	selection, so the same content should lead to the same filename.
		247
		248	After a successful upload the selection will be replaced by the text
		249	given in the "selection-pastebin-url" resource (again, the % is the
		250	placeholder for the filename):
		251
		252	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

		267	Argument names also often indicate the type of a parameter. Here are
		268	some hints on what they mean:
		269
		270	$text
		271	Rxvt-unicodes special way of encoding text, where one "unicode"
		272	character always represents one screen cell. See ROW_t for a
		273	discussion of this format.
		274
		275	$string
		276	A perl text string, with an emphasis on text. It can store all
		277	unicode characters and is to be distinguished with text encoded in a
		278	specific encoding (often locale-specific) and binary data.
		279
		280	$octets
		281	Either binary data or - more common - a text string encoded in a
		282	locale-specific way.
		283
		284	Extension Objects
		285	Very perl extension is a perl class. A separate perl object is created
		286	for each terminal and each extension and passed as the first parameter
		287	to hooks. So extensions can use their $self object without having to
		288	think about other extensions, with the exception of methods and members
		289	that begin with an underscore character "_": these are reserved for
		290	internal use.
		291
		292	Although it isn't a "urxvt::term" object, you can call all methods of
		293	the "urxvt::term" class on this object.
		294
		295	It has the following methods and data members:
		296
		297	$urxvt_term = $self->{term}
		298	Returns the "urxvt::term" object associated with this instance of
		299	the extension. This member must not be changed in any way.
		300
		301	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		302	Dynamically enable the given hooks (named without the "on_" prefix)
		303	for this extension, replacing any previous hook. This is useful when
		304	you want to overwrite time-critical hooks only temporarily.
		305
		306	$self->disable ($hook_name[, $hook_name..])
		307	Dynamically disable the given hooks.

		372	suppress the built-in processing. This can happen multiple times, as
		373	long as the callback returns true, it will be called on every
		374	further click by the user and is supposed to enlarge the selection

		396	state information is up-to-date when this happens. For
		397	interoperability, the string should start with the extension name
		398	and a colon, to distinguish it from commands for other extensions,
		399	and this might be enforced in the future.
		400
		401	Be careful not ever to trust (in a security sense) the data you

		403	messages from other users on the same system etc.).
		404
		405	on_add_lines $term, $string
		406	Called whenever text is about to be output, with the text as
		407	argument. You can filter/change and output the text yourself by
		408	returning a true value and calling "$term->scr_add_lines" yourself.
		409	Please note that this might be very slow, however, as your hook is
		410	called for all text being output.
		411
		412	on_tt_write $term, $octets
		413	Called whenever some data is written to the tty/pty and can be used
		414	to suppress or filter tty input.
		415
		416	on_line_update $term, $row
		417	Called whenever a line was updated or changed. Can be used to filter
		418	screen output (e.g. underline urls or other useless stuff). Only
		419	lines that are being shown will be filtered, and, due to performance
		420	reasons, not always immediately.
		421
		422	The row number is always the topmost row of the line if the line
		423	spans multiple rows.
		424
		425	Please note that, if you change the line, then the hook might get
		426	called later with the already-modified line (e.g. if unrelated parts
		427	change), so you cannot just toggle rendition bits, but only set
		428	them.

		439	on_keyboard_command $term, $string
		440	Called whenever the user presses a key combination that has a
		441	"perl:string" action bound to it (see description of the keysym
		442	resource in the rxvt(1) manpage).
		443
		444	on_x_event $term, $event
		445	Called on every X event received on the vt window (and possibly
		446	other windows). Should only be used as a last resort. Most event
		447	structure members are not passed.
		448
		449	on_focus_in $term
		450	Called whenever the window gets the keyboard focus, before
		451	rxvt-unicode does focus in processing.
		452
		453	on_focus_out $term
		454	Called wheneever the window loses keyboard focus, before
		455	rxvt-unicode does focus out processing.
		456
		457	on_configure_notify $term, $event

		466	Called whenever the corresponding X event is received for the
		467	terminal If the hook returns true, then the even will be ignored by
		468	rxvt-unicode.
		469
		470	The event is a hash with most values as named by Xlib (see the
		471	XEvent manpage), with the additional members "row" and "col", which
		472	are the (real, not screen-based) row and column under the mouse
		473	cursor.
		474
		475	"on_key_press" additionally receives the string rxvt-unicode would

		486	Variables in the "urxvt" Package
		487	$urxvt::LIBDIR
		488	The rxvt-unicode library directory, where, among other things, the
		489	perl modules and scripts are stored.
		490
		491	$urxvt::RESCLASS, $urxvt::RESCLASS
		492	The resource class and name rxvt-unicode uses to look up X

		500	object, whenever a callback/hook is executing.
		501
		502	@urxvt::TERM_INIT
		503	All coderefs in this array will be called as methods of the next
		504	newly created "urxvt::term" object (during the "on_init" phase). The
		505	array gets cleared before the codereferences that were in it are
		506	being executed, so coderefs can push themselves onto it again if
		507	they so desire.
		508
		509	This complements to the perl-eval commandline option, but gets
		510	executed first.
		511
		512	@urxvt::TERM_EXT
		513	Works similar to @TERM_INIT, but contains perl package/class names,
		514	which get registered as normal extensions after calling the hooks in

		557
		558	RENDITION
		559	Rendition bitsets contain information about colour, font, font styles
		560	and similar information for each screen cell.
		561
		562	The following "macros" deal with changes in rendition sets. You should
		563	never just create a bitset, you should always modify an existing one, as
		564	they contain important information required for correct operation of
		565	rxvt-unicode.
		566
		567	$rend = urxvt::DEFAULT_RSTYLE
		568	Returns the default rendition, as used when the terminal is starting
		569	up or being reset. Useful as a base to start when creating
		570	renditions.
		571
		572	$rend = urxvt::OVERLAY_RSTYLE
		573	Return the rendition mask used for overlays by default.
		574
		575	$rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
		576	Return the bit that enabled bold, italic, blink, reverse-video and
		577	underline, respectively. To enable such a style, just logically OR
		578	it into the bitset.
		579
		580	$foreground = urxvt::GET_BASEFG $rend
		581	$background = urxvt::GET_BASEBG $rend
		582	Return the foreground/background colour index, respectively.
		583
		584	$rend = urxvt::SET_FGCOLOR $rend, $new_colour
		585	$rend = urxvt::SET_BGCOLOR $rend, $new_colour
		586	Replace the foreground/background colour in the rendition mask with
		587	the specified one.
		588
		589	$value = urxvt::GET_CUSTOM $rend
		590	Return the "custom" value: Every rendition has 5 bits for use by
		591	extensions. They can be set and changed as you like and are
		592	initially zero.
		593
		594	$rend = urxvt::SET_CUSTOM $rend, $new_value
		595	Change the custom value.
		596
		597	The "urxvt::anyevent" Class
		598	The sole purpose of this class is to deliver an interface to the
		599	"AnyEvent" module - any module using it will work inside urxvt without
		600	further programming. The only exception is that you cannot wait on
		601	condition variables, but non-blocking condvar use is ok. What this means
		602	is that you cannot use blocking APIs, but the non-blocking variant
		603	should work.
		604
134	The "urxvt::term" Class	605	The "urxvt::term" Class
		606	$term = new urxvt::term $envhashref, $rxvtname, [arg...]
		607	Creates a new terminal, very similar as if you had started it with
		608	system "$rxvtname, arg...". $envhashref must be a reference to a
		609	%ENV-like hash which defines the environment of the new terminal.
		610
		611	Croaks (and probably outputs an error message) if the new instance
		612	couldn't be created. Returns "undef" if the new instance didn't
		613	initialise perl, and the terminal object otherwise. The "init" and
		614	"start" hooks will be called during this call.
		615
		616	$term->destroy
		617	Destroy the terminal object (close the window, free resources etc.).
		618	Please note that rxvt will not exit as long as any event watchers
		619	(timers, io watchers) are still active.
		620
		621	$term->exec_async ($cmd[, @args])
		622	Works like the combination of the "fork"/"exec" builtins, which
		623	executes ("starts") programs in the background. This function takes
		624	care of setting the user environment before exec'ing the command
		625	(e.g. "PATH") and should be preferred over explicit calls to "exec"
		626	or "system".
		627
		628	Returns the pid of the subprocess or "undef" on error.
		629
		630	$isset = $term->option ($optval[, $set])
		631	Returns true if the option specified by $optval is enabled, and
		632	optionally change it. All option values are stored by name in the
		633	hash %urxvt::OPTION. Options not enabled in this binary are not in
		634	the hash.

		686
		687	This method should only be called during the "on_start" hook, as

		848	Return various integers describing terminal characteristics.
		849
		850	$x_display = $term->display_id
		851	Return the DISPLAY used by rxvt-unicode.
		852
		853	$lc_ctype = $term->locale
		854	Returns the LC_CTYPE category string used by this rxvt-unicode.
		855
		856	$env = $term->env
		857	Returns a copy of the environment in effect for the terminal as a
		858	hashref similar to "\%ENV".
		859
		860	$modifiermask = $term->ModLevel3Mask
		861	$modifiermask = $term->ModMetaMask
		862	$modifiermask = $term->ModNumLockMask
		863	Return the modifier masks corresponding to the "ISO Level 3 Shift"
		864	(often AltGr), the meta key (often Alt) and the num lock key, if
		865	applicable.
		866
		867	$screen = $term->current_screen
		868	Returns the currently displayed screen (0 primary, 1 secondary).
		869
		870	$cursor_is_hidden = $term->hidden_cursor
		871	Returns wether the cursor is currently hidden or not.
		872
		873	$view_start = $term->view_start ([$newvalue])
		874	Returns the row number of the topmost displayed line. Maximum value
		875	is 0, which displays the normal terminal contents. Lower values
		876	scroll this many lines into the scrollback buffer.
		877
		878	$term->want_refresh
		879	Requests a screen refresh. At the next opportunity, rxvt-unicode
		880	will compare the on-screen display with its stored representation.
		881	If they differ, it redraws the differences.
		882
		883	Used after changing terminal contents to display them.
		884
		885	$text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		886	Returns the text of the entire row with number $row_number. Row 0 is
		887	the topmost terminal line, row "$term->$ncol-1" is the bottommost
		888	terminal line. The scrollback buffer starts at line -1 and extends
		889	to line "-$term->nsaved". Nothing will be returned if a nonexistent
		890	line is requested.
		891
		892	If $new_text is specified, it will replace characters in the current
		893	line, starting at column $start_col (default 0), which is useful to
		894	replace only parts of a line. The font index in the rendition will
		895	automatically be updated.
		896
		897	$text is in a special encoding: tabs and wide characters that use
		898	more than one cell when displayed are padded with $urxvt::NOCHAR
		899	(chr 65535) characters. Characters with combining characters and
		900	other characters that do not fit into the normal tetx encoding will
		901	be replaced with characters in the private use area.
		902
		903	You have to obey this encoding when changing text. The advantage is
		904	that "substr" and similar functions work on screen cells and not on
		905	characters.
		906
		907	The methods "$term->special_encode" and "$term->special_decode" can
		908	be used to convert normal strings into this encoding and vice versa.
		909
		910	$rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		911	Like "$term->ROW_t", but returns an arrayref with rendition bitsets.
		912	Rendition bitsets contain information about colour, font, font
		913	styles and similar information. See also "$term->ROW_t".
		914
		915	When setting rendition, the font mask will be ignored.
		916
		917	See the section on RENDITION, above.
		918
		919	$length = $term->ROW_l ($row_number[, $new_length])
		920	Returns the number of screen cells that are in use ("the line
		921	length"). Unlike the urxvt core, this returns "$term->ncol" if the
		922	line is joined with the following one.
		923
		924	$bool = $term->is_longer ($row_number)
		925	Returns true if the row is part of a multiple-row logical "line"
		926	(i.e. joined with the following row), which means all characters are
		927	in use and it is continued on the next row (and possibly a
		928	continuation of the previous row(s)).
		929
		930	$line = $term->line ($row_number)
		931	Create and return a new "urxvt::line" object that stores information
		932	about the logical line that row $row_number is part of. It supports
		933	the following methods:
		934
		935	$text = $line->t ([$new_text])
		936	Returns or replaces the full text of the line, similar to
		937	"ROW_t"
		938
		939	$rend = $line->r ([$new_rend])
		940	Returns or replaces the full rendition array of the line,
		941	similar to "ROW_r"
		942
		943	$length = $line->l
		944	Returns the length of the line in cells, similar to "ROW_l".
		945
		946	$rownum = $line->beg
		947	$rownum = $line->end
		948	Return the row number of the first/last row of the line,
		949	respectively.
		950
		951	$offset = $line->offset_of ($row, $col)
		952	Returns the character offset of the given row\|col pair within
		953	the logical line. Works for rows outside the line, too, and
		954	returns corresponding offsets outside the string.
		955
		956	($row, $col) = $line->coord_of ($offset)
		957	Translates a string offset into terminal coordinates again.
		958
		959	$text = $term->special_encode $string
		960	Converts a perl string into the special encoding used by
		961	rxvt-unicode, where one character corresponds to one screen cell.
		962	See "$term->ROW_t" for details.
		963
		964	$string = $term->special_decode $text
		965	Converts rxvt-unicodes text reprsentation into a perl string. See
		966	"$term->ROW_t" for details.
		967
		968	$success = $term->grab_button ($button, $modifiermask)
		969	Registers a synchronous button grab. See the XGrabButton manpage.
		970
		971	$success = $term->grab ($eventtime[, $sync])
		972	Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
		973	synchronous ($sync is true). Also remembers the grab timestampe.
		974
		975	$term->allow_events_async
		976	Calls XAllowEvents with AsyncBoth for the most recent grab.
		977
		978	$term->allow_events_sync
		979	Calls XAllowEvents with SyncBoth for the most recent grab.
		980
		981	$term->allow_events_replay
		982	Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for
		983	the most recent grab.
		984
		985	$term->ungrab
		986	Calls XUngrab for the most recent grab. Is called automatically on
		987	evaluation errors, as it is better to lose the grab in the error
		988	case as the session.
		989
		990	$atom = $term->XInternAtom ($atom_name[, $only_if_exists])
		991	$atom_name = $term->XGetAtomName ($atom)
		992	@atoms = $term->XListProperties ($window)
		993	($type,$format,$octets) = $term->XGetWindowProperty ($window, $property)
		994	$term->XChangeWindowProperty ($window, $property, $type, $format,

		1003	$y)
		1004	$term->XChangeInput ($window, $add_events[, $del_events])
		1005	Various X or X-related functions. The $term object only serves as
		1006	the source of the display, otherwise those functions map
		1007	more-or-less directory onto the X functions of the same name.
		1008
		1009	The "urxvt::popup" Class
		1010	$popup->add_title ($title)
		1011	Adds a non-clickable title to the popup.
		1012
		1013	$popup->add_separator ([$sepchr])
